Maintain common sense: A, if we want to avoid cement rotary kiln open parking during rapid warming and urgent cold damage of alkaline brick, except need applicable burning device outside, more important is to should conscientiously carry out the ignition heat and cold kiln system, cement rotary kiln temperature ℃ D30 per hour, insulation control ℃ above 300. Due to the cement rotary kiln alkaline brick thermal expansion coefficient of big, 1000 ℃ inflation approximately 1-1.2%, in the kiln temperature process, especially in bricky surface temperature 300-1000 ℃ area, the rate of temperature must be less than 60 ℃ / h. This in theory is very clear, in the course of execution have certain difficulty. And cement rotary kiln equipment long-term security operation is strictly enforce the ignition system and stop kiln cold kiln system foundation, if every cement rotary kiln ignition temperature can normal operation more than one month even months time, then used for cement rotary kiln ignition temperature the time and expense involved will be insignificant, but if the cement rotary kiln equipment state is bad, every month a few times even ten-tupling times, it is impossible to stop kiln ignition executed strictly heat and parking cold kiln system, because of frequent stop kiln every time use 20 hours to the kiln, from the time, the expense spend not, and rapid heat and cold kiln inevitably leads to rapid cement rotary kiln brick damage, so accident frequently, cement rotary kiln alkaline brick using life will not be too long, therefore, in use alkaline brick on the question of equipment also at the basic status. Second, cement rotary kiln skin of rotary kiln is barrier: to alkaline brick kiln skin protective effect is obvious to keep skin brick kiln extend the service life of alkaline, and protect vital kiln skin is the premise of pyrology system stability, because every time the stove temperature fluctuations of large skin will create a different degree of kiln damage. Cement rotary kiln maintenance work is vital, and therefore rotary kiln user friend must specially-designated person to operate the rotary kiln, and in the operator mount guard the systematic training before had better, and thus more can ensure our rotary kiln equipment running in production and prolong the service life of equipment!

Pressure Drop: Pressure drop, or differential pressure, is the amount of static resistance experienced when operating a positive or negative pressure baghouse. This pressure drop is typically measured across the filter bags in inches of water column (in. w.c.). Examples of some standard gauges used for this monitoring are a Magnehelic¨ gauge, Photohelic¨ switch/gauge and manometer. Pressure drop is a good indicator regarding the amount of dust that has collected on the filter media, and if continually monitored and logged, the condition of the bags themselves. New filter bags have the lowest pressure drop because of the inherent permeability of the media. As the bags develop a dust cake, some particulate embed themselves into the interstices of the filter media, and the pressure drop will increase accordingly. It is the filtering of the airstream through this accumulated dust cake that provides high efficiency collection of fine particulate. In fact, the highest efficiency a dust collector can offer is just before the cleaning mechanism is initiated. However, high differential pressures can cause bleed thru or blinding of the filter media. Therefore, it is suggested not to exceed the manufacturer's recommended operating pressure drop. Keeping a daily log of a baghouse's differential pressure, from the time the filter media is new, will provide the opportunity to diagnose problems that may occur (i.e., an increase in dust emissions, reduced ventilation air at the dust source, shortened bag life, etc.). Following an initial seasoning or conditioning period of filter bags, the pressure drop should stabilize into a consistent operating range relative to the cleaning cycle, application and style of equipment. Therefore, at subsequent bag changes, this operating range can be predicted. Deviation from this historical level will alert an operator to investigate the cause of such an occurrence. Cleaning System: Any method used by the equipment to dislodge accumulated dust cake from the filter media is its cleaning system. This may be reverse air, shaker or pulse clean. Regardless of the style of cleaning, it is imperative that this system function properly at all times. Without an effective cleaning system, dust will continue to build on the bags. The resultant will be an increased pressure drop and reduced volume of ventilation air at the pick-up points. Further, airstream velocities within the ductwork will decrease and cause drop-out of dust in the ducts. This may choke the entire system and render it ineffective. As indicated on our Inspection Logs, cleaning systems require more than just periodic monitoring. It is suggested that all components of the system be regularly inspected, and corrections made in a timely manner. Besides the items noted on the attached logs, refer to your OEM's Installation & Maintenance Manual to include other items specific to their equipment. Hopper Discharge: The hopper on a baghouse is not to be used for storage of the collected product, unless originally designed to do so. Storing material in a hopper can lead to bridging of the dust, or it may set up as a solid mass requiring considerable labor and down time to correct. Material build up, if not discovered in time, can fill a hopper to its inlet and plug the unit. Further, with low density materials, the airstream may sweep the dust into the bag section, ruining filter bags and clogging the dust collector. It is strongly recommended that whatever method is used for material discharge (rotary valve, screw conveyor/pneumatic conveyor, etc.) it should be inspected frequently. This inspection should also be followed at shut down and bag changes. Visible Emissions: Any particulate that can be seen discharging from the exhaust stack is considered visible emissions. These emissions are an indication that there is a breach in a seal or a broken (torn) filter bag. In either case, the leak must be found and corrected immediately. Not only will the emission cause a health concern and damage to property outside the plant, monetary fines imposed by the local EPA may also result. In addition, a fan located downstream of the collector can be damaged from abrasion or become imbalanced if this condition is not corrected quickly. The exhaust from a dust collector should be continually monitored and checked off in the Inspection Log. Besides visual inspections, one may consider incorporating a "Broken Bag Detector" into the clean air ductwork. Should a bag begin to fail or there be a leak in a bag seal, the particles that bypass the media will be detected. Typically, these detectors use triboelectric or scattered light technologies. These devices can be wired to an alarm horn, siren or flashing light for an immediate acknowledgement of an upset condition. Exhaust Fan: In a dust collection system, an exhaust fan is needed to accelerate ventilation air from the point of pick-up, through the ductwork and baghouse filter media, and out the exhaust stack. A fan is selected to accommodate each application with respect to volume (ACFM) and pressure drop throughout the system. This pressure drop is calculated by evaluating the static resistance of the baghouse, all ductwork and pickup points/hoods. (See page 16 for assistance.) Should an exhaust fan experience loose or worn belts or an imbalanced impeller, it will not exhaust the volume of air it was originally designed to handle. Without adequate ventilation air, a dust collection system will not operate effectively. Thorough fan inspections are to be performed on a semi-annual basis. However, any time unusual vibration, squealing, or other obvious variances from standard operation is observed, the original manufacturer is to be contacted for their evaluation and comment. Filter Media: The most important item in a baghouse is the filter media because it allows for the accumulation and support of a dust cake. This dust cake is what provides high filtering efficiencies during operation. Periodic inspections of the filter bags is mandatory. Inspect the clean air side of the baghouse for leaks, and the bags for tears. Should the pressure drop within a dust collector become extremely high, relative to historical data, it may be caused by excessive dust cake or blinding of the filter bags. Excessive dust cake is evident when visually inspecting the filter bags (when the dust collector is presumed to be clean) and finding them covered with a layer of the collected dust. Should this occur, one could suspect that the cleaning system is not functioning properly. However, if the dust cake has hardened to the bags and will not dislodge easily, the most probable cause is moisture in the baghouse. Moisture in a dust collector may have resulted from dew point excursions, high moisture content in the process gas, in the compressed air supply, or a leak in the collector or ductwork that allowed water to enter the dust collector. The other obvious cause of high differential pressure may have been caused by blinding of the filter bags. Blinding can occur from improper start-up conditioning of the filter bags following the previous bag change. See "Start-Up Procedures" for suggestions on how to minimize the possibility of blinding. Structural Integrity: The structural integrity of equipment can not only affect its performance, but cause health and housekeeping concerns, and reduced equipment life. An overall inspection should be done annually. It is suggested that the welds, joints and flange seals be inspected. Any leaks in the collector must be sealed either mechanically or by using silicone caulking. In a negative pressure system, a breach in a seal or weld will introduce ambient air into the collector. With this air, moisture and contaminants can find their way into the collector. In a positive pressure system, dust will blow out of the collector causing housekeeping problems and a potential health hazard to employees exposed to the dust. Look for the obvious. Check the structural support members for signs of fatigue and excessive corrosion. Be certain that all fasteners are in place and tightly secured, especially on the ladder and access platform. Replace any missing bolts, clean and re-weld any cross bracing or gussets that may have cracked welds. Look closely at the filter's external walls for corrosion or signs of bowing. Clean and repaint where necessary. Repair any holes that may have developed in the dust collector walls or hopper(s). Auxiliary Equipment: Aside from the baghouse itself, a thorough inspection of any system will include a check of all miscellaneous complimentary equipment. Some of these items may include the exhaust fan, rotary airlock valve, screw conveyor, inlet and/or outlet dampers, etc. It is very important that any ancillary equipment be added to the Inspection Log. Ductwork: Another important component in a ventilation system is the ductwork. If the particulate does not have an opportunity to reach the baghouse, the dust collector will not be able to perform its function. Standard practices suggest a minimum airstream velocity within any duct of 3500 feet per minute (fpm), and between 4000 and 4500 fpm for heavier dusts, such as sand. Should the dust travel at lower than adequate velocities, it will tend to settle and accumulate in the ducts choking the system. This restriction of flow will increase the pressure drop in the system, and the energy required to induce the air to move. The resultant will be reduced ventilation air at the pick up points. It is advisable to periodically inspect the entire length of ductwork for dust accumulation. (See page 17 for a list of dusts and recommended duct velocities.) Start-Up Procedures: Proper start-up procedures will help to extend the life of new filter media in a dust collector. What is generally accepted as "Start-Up" procedures is the process designed to intentionally develop a dust cake on the bags. This we refer to as seasoning or conditioning of the filter media. Seasoning of a collector's filter bags is one of the most important procedures a company can perform. In a fabric filter dust collector, the filter media is used to support a dust cake. A dust cake is the porous layer of collected particulate that develops during the conditioning period of new collector bags, and following each cleaning cycle. The process can be accelerated in many installations by introducing a precoat material such as agricultural lime into the system. Commercial precoats are also available. Following installation of the filter bags and inspection of the related auxiliary equipment, the exhaust fan can be started. However, it is extremely important that the new filter bags are not exposed to the full volume (ACFM) of the fan. A reduced volume is recommended during the seasoning process. Close the fan damper (or inlet dampers) to one half open until the monitoring gauge reads approximately 50 to 65% of the manufacturer's recommended maximum flange to flange differential pressure. Once at this level, fully open the damper and continue to monitor the pressure drop. At roughly 75% of the manufacturer's recommended differential pressure, the cleaning system can be initiated. Normal operation and periodic cleaning will bring the pressure drop to a calculable and historically stable level. Depending upon the application, development of this differential pressure may take a number of hours to a number of days. This is necessary to ensure that the new filter media is exposed to low filtering velocities of dust laden air. Reducing the volume decreases the airstream's velocity (air-to-cloth ratio) protecting the virgin bags from high velocity impingement of dust. Should the bags be exposed to the fan's full volume, fine particles may embed themselves into these inner fibers of the bags and begin a "blinding" condition. This can also damage the fibers of the media which will reduce the life of the bags.
