The dust removal equipment must be cleaned frequently during use. The advantage of dust removal is to avoid excessive dust causing clogging and increased pressure inside the dust removal bag to cause bursting. How can the dust removal equipment be effectively cleaned? This is the topic for everyone today. The dust removal method introduced below is ideal for the equipment.
1.Rock cleaning
With the help of mechanical vibration and percussion, or by mechanically shaking the frame of the hanging filter bag, the cloth bag of the dust collector equipment generates vibration to remove dust. This method is usually called vibrating ash cleaning, and its auxiliary machinery has a simple structure and stable and reliable operation. It is generally suitable for bag filter equipment such as textile cloth.
2.Back blowing dust removal
It adopts the working mode of separate chambers and automatically adjusts through the pulse valve, so that the blowing airflow passes through each compartment one by one to generate the airflow opposite to the filtered airflow. Compared with the vibratory ashing, the ashing effect of the reverse blow type ashing method has less damage to the filter bag. Generally, it is mainly aimed at the ash cleaning operation of the glass fiber filter bag.
3.Back-blow vibration combined dust removal
As the name suggests, back blow vibration combined with dust cleaning is a method of cleaning by combining vibration cleaning and back blowing cleaning. It is mainly used in the dust removal and dust removal operations of high-temperature glass fiber filter bags under the conditions of high dust removal requirements and unfavorable dust removal.
4, pulse spray cleaning
On the upper plate of the box of the dust collector equipment, there is a spray pipe above each row of fixed filter bags. Each spray pipe corresponds to a filter bag. The other end is connected to the pulse valve, the controller and the compressed air storage tank. Form a pulse control system, and control the spraying effect of the discharge pipe by controlling the pulse valve to realize the automatic dust cleaning operation. Because pulse spraying uses air compression, dew condensation and freezing are likely to occur in cold areas or outdoor use, which affects the cleaning effect. Therefore, this cleaning method is usually used indoors.
5.Pulse back blowing dust removal
It is similar to the pulse cleaning method described above, except that it uses the reverse air flow with pulse injection. The advantage of this method is that the cleaning effect is stronger. When we sequentially clean the part of the filter bag, it does not require a compartment structure. Form, so this method is favored by many users.
6.Air ring blowback dust removal
Since this cleaning method needs to be close to the surface of the filter bag through some hollow rings with seams, and the cleaning of the dust is performed by high-speed airflow, the design structure is more complicated, and the filter bag is easily damaged, so it will not be described in detail.
7.Pulse dust cleaning method of air box
In popular terms, it is the forced pulse cleaning method. The filter bag is mainly divided into several dust removal compartments. A partition is separated by a partition in the air purification box above the filter bag. There is no venturi tube on the filter bag. When cleaning the dust, proceed in order from room to room, close the exhaust valve, spray a pulse of air on the side of the cabin dust removal chamber, enter the dust removal filter bag through the sub-chamber, and use its impact and expansion to clean the dust.
