Introduction to the knowledge of cartridge filter

I. JWST series cartridge filter mainly has the following characteristics:

1. It adopts a vertical cartridge structure, which is convenient for dust adsorption and cleaning; Moreover, due to the small shaking of the filter material during ash removal, the service life of the filter cartridge is much longer than that of the filter bag, and the maintenance cost is low

2. The internationally advanced off-line three state (filtration, ash removal, static) ash removal method is adopted to avoid the phenomenon of "re adsorption" during ash removal and make the ash removal completely and reliably

3. It is designed with a pre dust collection mechanism, which is not 0731 ⑵) but it overcomes the shortcoming that the filter cartridge is easy to be worn out by the direct erosion of dust, and can greatly improve the dust concentration at the inlet of the dust collector

4. The key components that affect the main performance (such as pulse valve) are imported parts, and the service life of the vulnerable part diaphragm is more than 1million times

5. Using the separate injection and dust removal technology, one pulse valve can inject one row at the same time (the maximum number of filter cartridges in each row is 12), which can greatly reduce the number of pulse valves

6. The three state ash cleaning mechanism of pulse valve adopts PLC automatic control, and has two control modes: timing or manual

7. Any combination of filter cartridges with different columns and rows can be used according to the needs of installing empty 7. Clamping the sample between the ends of sensor 1 first; The three-dimensional space occupied by the unit filter area is small, which can save a lot of space resources for users and indirectly reduce the one-time investment cost of users

8. Long service life. The service life of the filter cartridge can reach 2 ~ 3 years, which greatly reduces the times of replacing the filter element of the dust collector (the filter element of the traditional bag filter is replaced every 6 months on average). The maintenance is simple, which greatly reduces the maintenance cost of users in the process of use

9. This product is widely applicable to the purification and treatment of industrial dust in iron and steel metallurgy, non-ferrous smelting, construction cement, mechanical casting, grain light industry, daily chemical industry, tobacco, storage dock, industrial power station boiler, heat supply boiler, urban waste incineration and other industries

II. Equipment structure and working principle:

1. Structure: this dust collector is composed of six parts: upper box, ash hopper, ladder platform, support, pulse ash removal and ash discharge device

2. Working principle: under the action of the main fan of the system, the dusty gas flows from the dust collector. Therefore, it must be ensured that the oil pump is under the condition of no vibration. The lower air inlet enters the air box at the bottom of the dust collector for the pretreatment of the dusty gas, and then enters the dust removal rooms of the upper box from the bottom; The dust is adsorbed on the outer surface of the filter cartridge, and the filtered clean gas enters the clean gas chamber of the upper box through the filter cartridge and is collected to the air outlet for discharge. As the filtration condition continues, the dust accumulated on the outer surface of the filter cartridge will accumulate more and more, which will correspondingly increase the operating resistance of the equipment. In order to ensure the normal operation of the system, the upper limit of the resistance of the dust collector should be maintained within the range of 1400 ~ 1600pa. When this limit is exceeded, the PLC pulse automatic controller should send instructions through constant resistance or timing to remove the dust in three states. The dust cleaning process of the cartridge filter is to first cut off the net gas outlet channel of a room to make the room in a static state of air flow, and then carry out compressed air pulse back blowing for dust cleaning. After several seconds of natural sedimentation, open the net gas outlet channel of the room, which not only cleans the dust thoroughly, but also avoids the secondary adsorption of dust generated by blowing and cleaning, so as to clean the dust circularly room by room
