Polyester Filter Bag

 1. Introduction of polyester filter bag

 

In recent years, countries around the world have made many efforts in the treatment of environmental pollution and achieved great results. In the treatment of air pollution and material recovery, bag dust removal has achieved good results. The technical core of bag dust removal is the filter material. Bag dust removal is using polyester filter felt to filter the dust in the gas.

 

2. Performance requirements of polyester filter bag

 

People have many requirements for the performance of filter media of polyester filter bag. The main performance requirements are: large air handling capacity, low resistance, long life, and low price.

 

The filter cloth used for dust filtration mainly consists of organic woven filter cloth and needle punched filter cloth.

 

Woven filter cloth is made of twisted warp and weft yarns interlaced on a plane, with a two-dimensional structure. The woven filter material requires a great degree of tightness when weaving the cloth, and the density of the yarn itself and the interweaving part of the filter material is also higher. The actual total opening rate is about 30%, and the resistance of the filter material is greater. The air handling capacity is small, and most of the dust-containing gas can only pass through the pores between the warp and weft threads. Because the pores are large and the direct dust is easily penetrated, it can only be better after the dust layer is formed on the woven fabric. The collection efficiency is low at the beginning of use and a period of time after cleaning. In addition, dust removal is a working procedure that constantly occurs in bag dust removal, which determines the low efficiency of woven filter cloth in bag dust removal.

 

3. Application of polyester filter bag

 

Polyester filter bags are used for air pollution control and material recovery, and are suitable for working at a temperature of 125°C-140°C.

The Electromagnetic Valve 2019

Electromagnetic pulse valves (also known as diaphragm valves) are compressed air "switches" for pulse bag filter dust cleaning systems. By the control of the output signal of the pulse jet control instrument, the filter bag is cleaned by one row (chamber), so that the resistance of the filter is kept within the set range, so as to ensure the processing capacity and dust collection efficiency of the filter. DMF-Z electromagnetic pulse valve  is a right-angle valve, and the angle between the inlet and outlet is 90 degrees, which is suitable for the installation connection between the airbag and the dust blower tube. The air flow is unobstructed and it can provide the required clear air pulse. DMF-ZM electromagnetic pulse valve is the same as the "Z" series of the right-angle valve, suitable for airbag and dust collector spray pipe installation connection, the import and export of the two ends with a fixed nut for installation so that installation and us...

Ash Discharge Valve

The opening and closing part of the ash discharge valve  electric plug valve is a gate plate, and the direction of movement of the gate plate is perpendicular to the direction of the fluid. The electric plug valve can only be fully opened and fully closed and cannot be adjusted or throttled. The gate has two sealing surfaces. The two sealing surfaces of the most commonly used mode gate valves form a wedge, and the wedge angle varies with the valve parameters. Principle: There is a round opening of a diameter on the gate, and the opening and closing of the gate makes the round opening on the gate to completely separate from and match with the diameter. Electric three-way valves are used for air conditioning, thermal ventilation, heat treatment in heat treatment plants, and industrial fluid control. Air-conditioning, heating, ventilation, domestic hot water and other civil systems and chemical, petroleum and metallurgical and fluid automation. Our dust collection s...
