The operating temperature of the application of central dust collector should be considered according to the long-term operating temperature. In order to avoid condensation, the flue gas temperature of the application of central dust collector should be kept 15 ~ 20℃ higher than the dew point. When purifying the high temperature gas whose temperature is close to the dew point, the relative humidity of the gas should be reduced by indirect heating or by mixing the high temperature gas.

When running the application of central dust collector, you should observe the state of the differential pressure system for faults. Record the pressure difference value of the pressure difference system in the application of central dust collector accurately. If sudden pressure difference is found in the recording process, it is necessary to check the filter bag to see whether there is blockage or dust compaction. At the same time, the ash cleaning system should be accurately checked to avoid excessive ash accumulation in the ash hopper. If there is a sharp drop during the recording process, it may be that the filter bag is damaged or is falling off.

application of central dust collector has the advantages of simple structure, low investment cost, simple operation, low technical requirements for management and maintenance. When the flue gas containing dust enters the middle and lower box by the inlet of the dust collector, the dust is adsorbed on the dust filter bag, and the gas enters the upper box through the Venturi tube through the filter bag, and is discharged from the outlet. With the accumulation of dust on the filter bag, the pressure loss of the filter bag gradually increases, and the pressure loss is fed back to the controller by the pressure gauge. The controller receives and issues instructions to trigger each pulse solenoid valve in sequence, so that the gas in the air bag is sprayed instantaneously from the holes of the spray pipe, and the pipe is sprayed into the corresponding filter bag. The filter bag does not expand slowly under the instantaneous reaction of the air flow, so that the dust accumulated on the surface of the filter bag falls off, and the filter bag can be recycled and reused. Field observation of a large number of damaged filter bags shows that the damaged parts of the filter bags are almost circular holes and long cracks. The test also showed that the undamaged part of the damaged filter bag and other filter bags in the filter unit were not significantly deformed, and the good residue rate was basically normal. This shows that the polymer fiber filter material does not have significant cracking during use.

application of central dust collector What are the design requirements? Here is a detailed introduction for you:

1. After the box, bag room, inlet and outlet, ash hopper and other equipment, all the joints should be airtight, requiring welding and sealing, implementing airtight welding, connecting with fasteners, with sealing gaskets, and tightening all fasteners. For part of the air leakage, silicone or epoxy resin is applied to stop the leakage rain. The sealing quality of the dust collector is an important factor affecting the normal operation and life, and the application of central dust collector requires that the air leakage rate is less than 3%.

Second, when assembling the gas route part, the main gas pipe has been made in the factory, and the site only needs to be assembled. The control gas pipe (connecting the lifting valve cylinder) should be unloaded, cased and other equipment on the site, requiring all pipelines to be organized and clean, without any debris, all joints should be filled with sealing materials, and the pressure test does not leak.

Third, the equipment bag cage and filter bag is a careful and careful operation in all equipment, so it should be placed in the final equipment, the filter bag must not bump with sharp objects, hook and scratch, even small scratches, will shorten the life of the dust filter bag. The method of filter bag is to first put the dust bag into the bag room by the box flower plate hole, and then pinch the spring ring at the top of the bag mouth into a concave shape, put it into the box flower hole plate, and then restore the spring ring, so that it is tightly pressed on the circle of the flower hole, and finally the bag cage is gently pierced from the bag mouth until the upper cover of the bag cage is indeed pressed on the box inside the flower plate hole to stop. In order to avoid damage to the filter bag, it is required to install a dust removal skeleton for each filter bag. Filter bag, dust bag cage and flower hole plate equipment.

Fourth, after the bag cage on the application of central dust collector for coal grinding is installed, the equipment should also be pressed so that the ground wire, bag cage and flower plate on the filter bag can be tightly touched. The door on the air box pulse bag dust collector for coal mill does not need to be adjusted when the equipment has been adjusted before leaving the factory.

5, the application of central dust collector lifting should pay attention to avoid deformation, in the equipment factory, the key components are welded with lifting ears, please use lifting ears for lifting.
