Precautions for use of filter bag dust collector: The type of filter bag dust collector should be determined according to the conditions of use and flue gas temperature, etc., and the filtering wind speed of the filter bag used should be determined.
If an air box pulse bag filter is used, a bag filter with 64 filter bags in a single room and 6 rooms is selected, that is, PPC 64-6. The total number of filter bags is 384, and the total filter area is:
384 square meters. Therefore, the filtering wind speed is 26000/60/384 = 1. 13m / min, which meets the requirements and the selection is reasonable. If the filter wind speed is 1. If the air volume is processed at a speed of 2m / min, 26000 m3 / h can be selected.
The filter bag to be filtered is: 26000/60 / 1.2 = 362 square meters. 过滤袋. If you choose a 130 * 2450 filter bag, the filter area of each filter bag is 1 m2, about 362 filter bags.
如果体温低于露点，滤袋会受潮，导致灰尘不散而是粘在滤袋上，堵塞织物孔眼，导致除灰失败，造成除尘器压力下降. 太大无法继续运行，产生的一些膏体袋无法除尘. During use, especially when using a filter bag filter under negative pressure, the gas must be prevented from cooling below the dew point of the room. As air often leaks into the housing, if the air temperature is below the dew point, the filter bag will be damp and cause dust Instead of scattered, it sticks to the filter bag, clogging the holes of the fabric, leading to the failure of ash removal, which causes the pressure of the dust collector to fall. It is too large to continue running, and some of the paste bags cannot be dusted.
Precautions for use of filter bag dust collector: The application technology of bag dust collectors has also made great progress. (高温、高湿度、高粉尘浓度、细粉尘、吸湿粉尘、腐蚀、易燃、运行条件波动大等). )预防、合理操作和维护制度建设 等人. 更加可靠和完善，这是其应用领域不断扩大的重要原因. Faced with changing production processes and dust properties, equipment selection, parameter determination, various adverse factors (high temperature, high humidity, high dust concentration, fine dust, hygroscopic dust, corrosion, flammability, large fluctuations in operating conditions, etc.) ) Prevention, reasonable operation and maintenance system construction, etc .. More reliable and perfect, which is an important reason for its expanding application field.
It is worth mentioning that in China's long-term electrostatic precipitator-based coal-fired power plant boiler flue gas dust removal field, filter bag dust collectors have been used.
Precautions for use of filter bag dust collector: Filter bag dust collectors should pay special attention to measures to prevent combustion, explosion and fire accidents. 火星、燃烧和爆炸性气体进入系统. 有些灰尘具有自燃或带电的性质. 同时，大多数过滤材料都很容易制成. When dealing with combustion gas or high temperature gas, there is usually incomplete combustion of dust, Mars, combustion and explosive gases enter the system. Some dusts have spontaneous combustion or charged properties. At the same time, most filter materials are easy to make.
Combustion and friction are prone to static electricity accumulation. Under such operating conditions, there is a danger of combustion and explosion accidents. The consequences of such accidents are often very serious.
The research on the dust removal mechanism of filter bag dust removal equipment is getting deeper. Practice has proved that the decisive factor affecting the dust removal effect of the filter bag is not the air volume and duration, but the dust removal effect.
研究结果对袋式除尘设备的研制、选型和检验起到了非常积极的指导作用. When the pressure in the filter bag reaches the peak value, the pressure rise speed and the amount of reverse acceleration that can be obtained from the bag wall; The dust removal strength of several bag dust collectors was tested. Inspection has played a very active guiding role.
