Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and the detailed description. It should be understood that the detailed description and specific examples, while indicating the scope of the utility model, are intended for purposes of illustration only and are not intended to limit the scope of the utility model.

The cathode is made of metal wires with different cross-section shapes and is called a discharge module. The positive pole is made of metal plates with different geometric shapes, called dust collecting module.

The gas filter, also called air filter screen or air filter, is a component for collecting dust from gas-solid two-phase flow and purifying gas by the action of porous filter material. Generally, the higher the grade of the gas filter, the greater the wind resistance. The filtering levels can be classified according to different criteria, such as a classification table of one of the division criteria shown in fig. 1.
