1、 Working principle of pulse filter cartridge dust collector Pulse filter cartridge dust collector; For negative pressure operation, the dusty airflow enters the box from the air inlet located at the upper part of the dust collector. The guide plate inside the box forces the airflow to pass through the filter cartridge downwards. Due to the sudden expansion of the airflow section, some coarse dust particles in the airflow settle under the action of gravity and inertia. Fine and low-density dust particles enter the filter chamber and deposit on the surface of the filter material through a combination of Brownian diffusion and screening effects. The purified air enters the clean room through the filter material and is discharged from the air outlet. When the dust accumulates more and more on the surface of the filter material and the resistance reaches the set value, the pulse valve opens, and compressed air is directly sprayed into the center of the filter cartridge to sequentially pulse clean the filter cartridge, shake off the accumulated dust, and restore its low resistance operation. The dust collected in the ash hopper is continuously discharged through the ash discharge valve. When repairing, simply manually unscrew the handwheel on the maintenance cover to easily remove the filter cartridge. 2、 Which design form is better for a pulse filter cartridge dust collector? There are three types of pulse filter cartridge dust collectors: horizontal, vertical, and diagonal. At first, pulse filter cartridge dust collectors were usually designed horizontally or diagonally, and the equipment looked very beautiful. Beautiful is beautiful, but there are always reasons for its imperfections. Nowadays, most pulse filter cartridge dust collectors are designed with vertically installed filter cartridges. The appearance of vertically installed pulse filter cartridge dust collector is similar to that of bag filter equipment, but compared with bag filter equipment, the purification effect of filter cartridge dust collector equipment is suitable for handling particularly fine dust, and the purification effect is also very good. It can be said that the purification effect is comparable to that of a bag filter. Why choose a vertically installed pulse filter cartridge dust collector? It is obvious that vertically installing a pulse filter cartridge dust collector still has advantages. When installing pulse filter cartridges horizontally or diagonally for dust removal, it is easy to accumulate dust and result in poor cleaning efficiency. The vertically installed pulse filter cartridge dust collector is more efficient in cleaning dust without any difficulty, which is also the reason why vertically installed pulse filter cartridge dust collectors became more popular later on. 3、 Introduction to Pulse Filter Cartridge Dust Collector When operating industrial equipment in factories, it is inevitable to form a lot of dust, which can cause harm to workers' bodies. Therefore, corresponding dust removal equipment is needed to solve this problem. Pulse filter cartridge dust collectors are used to facilitate dust adsorption and cleaning, and due to the small shaking of the filter material during cleaning, the maintenance cost of the filter cartridge and filter bag is low. The design includes a pre dust collection mechanism, which not only overcomes the disadvantage of direct dust flushing and easy wear of the filter cartridge, but also increases the dust concentration at the inlet of the filter. Filter cartridges with different numbers of columns and rows can be combined according to the installation space requirements; The unit filtering area occupies a small three-dimensional space, which can save users a lot of space resources and indirectly reduce their one-time investment costs. Long service life, the service life of the filter cartridge can reach 2-3 years, which reduces the number of times the dust collector needs to replace the filter element. Easy maintenance reduces maintenance costs for users during use. The characteristics of the dust removal filter cartridge are: a star shaped filter cartridge formed by folding the filter material into pleats with a straight length, and bonding the ends together. The filter cartridge has no cage bone and is easy to install. 1. Improved filtration area. 2. A low and stable pressure difference increases the flow of air. 3. The filter element is compact and easy to install. 4、 The fixing problem of the filter element in the pulse filter cartridge dust collector. The general design methods for pulse filter cartridge dust collectors are horizontal insertion and vertical insertion. The vertically mounted pulse filter cartridge dust collector is more convenient and clean in cleaning dust. The horizontally inserted pulse filter cartridge dust collector is more prone to dust accumulation in terms of cleaning. The vertical pulse filter cartridge dust collector is now recognized by customers and friends. Generally, pulse filter cartridges with filter cartridges installed from above, also known as vertical pulse filter cartridges, are equipped with filter cartridges made of different materials. Some are fixed with screws, while others are fixed with compression plates. The fixing method of the horizontal filter cartridge dust collector equipment is also generally similar. 5、 The maintenance of pulse filter cartridge dust collector is easy to break down after prolonged use, so regular maintenance is needed. So how to maintain it well? A large amount of investigation and statistical materials indicate that if operational management is not taken seriously in daily life, even the best pulse filter cartridge dust collector cannot fully exert its performance, and may even encounter various malfunctions, making it difficult to operate normally. If the maintenance and operation personnel are experienced and responsible, even if there are some shortcomings in the design and manufacturing of the equipment, under normal operating and maintenance conditions, the pulse filter cartridge dust collector can operate for a long time with lower operating costs. From this, it can be seen that the maintenance and management of pulse filter cartridge dust collectors is an optional issue, but a very important and important one. Below, we will introduce the maintenance and management issues related to pulse filter cartridge dust collectors. 1. The filter cartridge should be cleaned regularly, requiring oil-water separation, and the air bag should be drained in a timely manner. Regularly check the opening and closing of the air ducts inside the dust collector, and control the air used for cleaning. Check the degree of blockage, if mild blockage is found, it should be promptly removed, dried, and cleaned by tapping. Maintain normal ventilation capacity to avoid blockage and continue to operate in a vicious cycle. 2. Regularly check for air leaks in the exhaust gas treatment system, implement leak prevention measures, and provide external insulation for the exhaust gas system after grinding. 3. Pay attention to controlling the feeding speed; The circular flow mill can increase the amount of powder return and improve the air temperature inside the mill. Before stopping the grinding, try to extend the stopping time as much as possible, stop the mixing of materials with high moisture content as early as possible, extend the exhaust time inside the grinding appropriately after stopping the grinding, and at the same time, do a good job of rotating the grinding body.
