Features of high-quality filter cartridge dust collector

The high-quality filter cartridge dust collector has the characteristics of dust removal effect, large processing air volume, automatic dust removal technology, small pressure loss, good adaptability and flexibility. These characteristics make the filter cartridge dust collector widely used in the industrial field, which provides reliable technical support for protecting the environment and ensuring production.

Industrial process of bag filter

In the industrial dust collector, the industrial process of the bag filter is that when the dust-containing gas passes through the filter cloth, the voids between the filter cloth fibers or the voids adsorbed on the surface of the filter cloth are separated by dust larger than the diameter of the voids, which is called the sieving effect. For the new filter cloth, due to the large gap between the fibers, this effect is not obvious, and the dust removal efficiency is also low. Only after a certain period of use, a certain thickness of dust layer is established on the surface of the filter bag, and the screening effect is also significant. After cleaning, due to the surface of the filter bag and a certain amount of dust remains inside, it can still maintain a good dust removal efficiency. For needle felt or fleece itself constitutes a thick porous filter layer, can be more fully play the role of screening, do not rely entirely on the dust layer to maintain a high dust removal efficiency. When the dust-containing gas passes through the filter cloth fiber, the dust larger than 1um will still maintain a linear motion due to the effect of inertia and hit the fiber and be trapped. The larger the diameter of the dust particles, the greater the inertial effect. The higher the filtering air speed, the greater the inertial effect, but the air speed is too high, the amount of air passing through the filter cloth also increases, and the air flow will break through the weak part of the filter cloth, resulting in low dust removal efficiency. The higher the gas velocity, the more serious the penetration phenomenon.

When starting up, first turn on the compressed air to the storage pipe, turn on, control the power supply, and start the ash discharge device. If there are other equipment in the system, the interlock control should be controlled according to the process requirements. When the bag dust collector is working 2. When the dust collector is working normally, the ash discharge device cannot stop working.

What equipment does the bag filter belong

Bag dust collector is a kind of dust filtering equipment, its function is to use the filter cloth to keep the large dust particles on the filter cloth, and the small particles stay on the initial layer of the filter cloth. On the bag dust collector, the dust collector and the filter material act as a sieve, which is simply what it means. Equivalent to a dry dust collector, is specifically for dust removal equipment does not contain moisture, divided into vibration, air ring blowback, pulse and other types. His role is very wide, for mining, cement, building materials, food and other projects is a very ideal environmental protection equipment. Bag filter is a kind of dry filter equipment, dust removal efficiency is high, and the dust removal efficiency can reach more than 99% by the dust filter, while the dust concentration is low, widely praised by industrial manufacturers.

Description of cartridge dust collector

Overview of filter cartridge dust collector: 1. The filter cartridge dust collector adopts the filter cartridge structure, which is convenient for dust adsorption and dust removal; at the same time, the dust removal is convenient, the service life of the filter cartridge is much higher than that of the filter bag, and the maintenance cost is also low. 2. The filter cartridge dust collector not only overcomes the dust direct erosion easy to wear the filter cartridge, but also can greatly improve the dust collector treatment concentration. 3. The key components that affect the main performance of the soil are imported components, and their easy-to-use life exceeds 1 million times. 4. The use of separate injection cleaning technology, a pulse valve can be blown at the same time, can greatly reduce the number of pulse valve. 5. Pulse valve three-state ash removal mechanism using PLC automatic control, and both timing or manual two kinds of control mode optional. 6. According to the needs of the installation space, the number of different columns, the number of rows of filter cartridges can be used in any combination; the three-dimensional space occupied by the unit filter area is small, which can save a lot of space resources and reduce the one-time investment cost of the user.

Specifications and models of various materials of dust collector bags

Commonly used dust collector bag: Bag size range of bag filter. Generally, the specifications of filter bags used in bag filter are as follows: diameter: 120mm, 130mm, 133mm, etc. The lengths are: 1000mm, 1500mm, 2000mm, etc. Generally used circular bag specifications include φ 133*1000, φ 133*1500, φ 133*2000, etc. φ 133*2000 is used more. There are many factors to consider in determining the size of the dust collector bag. The length of the dust collector bag, in the case of the same amount of flue gas, filtration speed and dust collector bag diameter, increasing the length of the dust collector bag can reduce the number, thereby reducing the area occupied, reducing the solenoid valve of the dust removal system, pulse valve, blowpipe and other components, saving investment, but also can shorten the dust removal cycle. The shape of the dust collector bag is mainly divided into round, flat and special-shaped. According to the filtering method, it is mainly divided into: internal filter type and external filter type, which can also be selected according to the nature of dust.

Characteristics of bag filter

1 The design is novel, the air intake structure is adopted, and the coarser high temperature particles fall directly into the ash hopper, which effectively protects the filter bag. The use of long filter bag, in the same processing capacity when the equipment covers an area of less, more convenient for the transformation of the old plant. 2 The use of sub-chamber separation line cleaning, high efficiency, less secondary adsorption of dust, while effectively reducing the energy consumption of the equipment, the fatigue degree of the filter bag and the pulse valve is also reduced accordingly, doubling the life of the filter bag and the valve plate, greatly reducing the cost of equipment operation and maintenance. 3 Maintenance and bag replacement can be carried out in different chambers under the condition of non-stop system fan and normal operation of the system. 4 The filter bag mouth adopts a spring tension structure, which is convenient for disassembly and assembly and has good sealing performance. 5 The box body is designed for air tightness, and kerosene is used to check for leaks, and Z greatly reduces air leakage. 6 The whole equipment is controlled by PLC machine to realize automatic ash cleaning, ash unloading, automatic temperature control and over-temperature alarm.

In the workshop, what kind of dust removal equipment do we use better?

Most of the grinding workshops are made of color steel plates and semi-enclosed grinding rooms. Workers operate in the room. Due to the effect of the exhaust fan of the ventilation and dust removal system, the room is in a negative pressure state. The dust generated during polishing is effectively restricted in the polishing room, collected by the dust removal unit, and discharged after being treated by the filter cartridge dust collector. It can effectively control dust leakage, protect the production environment, and discharge to meet relevant standards. The filter cartridge filter element is used in the design of dust removal in the polishing workshop. It should be considered that the polishing table is generally used indoors, with a small floor area but a large dust removal area. The key is to facilitate dust removal. In the design, it should be considered to reduce the dust removal time and times of manual disassembly and assembly of the filter cartridge by workers. If cloth bags are used in the design of dust removal equipment in the polishing workshop, it must be considered that the polishing table is in a closed room, the size of the indoor area and the height of the workshop must be considered, and then the dust removal area must be large, and it must be convenient to remove dust at critical moments, and it can automatically remove dust. The installation position of the cloth bag dust collector must also consider the safe position for workers to replace the cloth bags and skeleton, therefore, this pulse bag filter is installed in the grinding workshop, which requires a lot of space.
