Description

Bipolar filter bag

Technical Field

The utility model relates to an industrial dust removal technical field especially relates to a bipolar filter bag.

Background

The filter bag has excellent chemical property stability and heat resistance, is a representative of the highest performance in the filter material industry, is also a variety with the highest performance in all common filter materials, and achieves higher levels in the aspects of filter efficiency, filter precision and the like, and the common filter materials comprise PE, PP, PTFE, PM IA, NMO and the like.

The bag type dust collector is a dry type dust filtering device. It is suitable for trapping fine, dry, non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt, the dust-containing gas is filtered by the filtering action of the fiber fabric, when the dust-containing gas enters the bag type dust collector, dust with large particles and large specific gravity falls into the dust hopper due to the sedimentation of the gravity, and when the gas containing fine dust passes through the filter material, the dust is blocked, so that the gas is purified.

In the existing dust collector, a bag type filter generally adopts a non-polar filter bag or a unipolar filter bag, so that the filter effect is poor and the dust removing time is long.

An object of the present invention is to provide a bipolar filter bag to solve the above technical problems.

The utility model discloses a solve above-mentioned technical problem, adopt following technical scheme to realize:

the utility model provides a bipolar filter bag, including the bag body, the filter cloth of the bag body comprises one deck long fiber layer and two-layer short fiber layer, and the short fiber layer sets up respectively in the both sides on long fiber layer, and the warp and the woof on short fiber layer are made by cathode fiber material and the mixing of anode fiber material.

Preferably, the diameter of the cathode fiber material and the anode fiber material in the short fiber layer is 0.8-1.2D, and the length is 38-50 mm.

Preferably, the long fiber layer is made of long fiber of PTFE.

Preferably, the filter cloth of the bag body is made of a long fiber layer and a short fiber layer by a spinning device.

Preferably, the bag body is made of filter cloth through high-temperature bonding.

The utility model discloses in, made the short-staple layer through the mixture of cathode fiber material and anode fiber material, realized taking the effect of different charges at the different positions of same filter bag, realized adjusting the absorption of negative charge dust well to realize the adsorption filtration of fine particle. In the working process, the positive electrode and the negative electrode are adopted under the voltage of 10kV and generate a corona area, dust is charged after the dust collides with charges, the dust with negative electricity is adsorbed on the anode under the action of an electric field, and the dust with positive electricity is adsorbed on the cathode, so that electrostatic dust removal is realized. Therefore, when the dust is removed by the method, the method has the advantages of high filtering effect, shorter dust removal time and the like. The long fiber layer has the advantages of easy ash removal, oxidation resistance, high strength, acid and alkali resistance and high temperature resistance due to the material characteristics of the long fiber layer. The utility model discloses in accord with short-staple layer and long fiber layer and form the filter cloth to the filter bag is made in the processing, consequently makes the performance of filter bag more optimize.

The utility model has the advantages that: the utility model provides a bipolar filter bag can realize the effect of taking different charges at the different positions of same filter bag, realizes adjusting the absorption of negative electric charge dust, consequently effectual reinforcing filter effect to possess easy deashing, anti-oxidant, intensity height, acid and alkali-resistance with advantages such as high temperature resistant.
