Improve the cleaning effect of pulse dust collector and work process

(1) to determine the way the pulse dust cleaning, first of all to determine the amount of combustion flue gas. The size of the filter area determines the size of the dust collector, if the estimate is large, the initial investment in equipment, there will be no problem running. However, if the flue gas is estimated to be small, the actual filtration speed is large, resulting in equipment resistance, poor cleaning, difficult to long-term continuous operation.

(2) and then pay attention to the dust filter bag material. If the filter is not appropriate, the machine's life will be greatly affected, if you consider replacing the filter, then the cost is relatively high. We used Ryton filter in the acid resistance, hydrolysis resistance, wear and other aspects of the performance are good, the price is not too expensive, in addition to these, Ryton's advantage is also expressed in the flue gas oxygen content is lower than its ability by the degree, you can achieve good results. Of course, there are many other materials, in short, all kinds of materials have its advantages and disadvantages, but only with the overall fit is the most important.

(3) The third is to pay attention to the acid dew point of the flue gas. When the flue gas temperature is lower than the acid dew point, the condensation of the acid produced by the corrosion device and the formation of dust on the filter material bonding. So the bag filter to take some measures, such as ash bucket heating, hot air circulation, pipe bypass, equipment insulation, flue gas heating and so on.

(4) the last point is to pay attention to the choice of equipment selection. In this regard, especially the components of the pulse injection system components, components, the inspection door, ash, ash storage device, dust filter bag and flower board, dust skeleton design and processing quality (finish and vertical, etc.) are Should be good, otherwise it will affect the long-term good operation of the device.

The components of the pulse bag filter and the work process：See the above picture.

Inlet duct, ash bucket and body are the main components of pulse bag filter, pulse bag filter is currently the most widely used dust removal equipment.

Often, the dust in the industry is first introduced into the pulsed bag filter through the air duct, and some of the larger dust particles fall to the bottom of the dust hopper and the smaller dust will follow the air the direction of the machine into the box and the lower box, the dust will stick to the top of the dust bag, filter dust after the dust from the top of the box has been into the net exhaust pipe duct, the last exhaust Put these dusty gases out.

In the process of cleaning the pulse bag dust collector, in order to be able to make the sub-room without air flow, to achieve the air shut down, the dust collector will block the sub-room clean air outlet duct; after the dust collector's pulse valve will open, by compression of the air cleaning, that is, pulse jet cleaning method. After the shut-off valve is closed, the pulse jet cleaning method will cause the dust particles on the dust bag to fall into the hopper. Cleaning process, the dust will not leave the bag followed by the air with the other filter bag to the outer layer, to achieve the purpose of cleaning thoroughly, while the pulse bag filter exhaust, unloading ash and pulse valves can be controlled by the program.
