Flue gas filtering and purifying device for vacuum filter

Abstract

The invention discloses a flue gas filtering and purifying device for a vacuum filter, and particularly relates to the field of vacuum filters. The device comprises a filter cavity, a control motor, a driving shaft, a circulation hole and a sealing sleeve, wherein the top end of the filter cavity is provided with a mounting hole and an air inlet, and the bottom end of the air inlet is attached to a sealing ring. According to the invention, through the cooperation of filtering discs and filtering strips, the problems that the flue gas filtering and purifying effect is poor and the requirement of comprehensive purification cannot be met in the prior art are avoided, the filtering discs are driven to rotate at a high speed in the filter cavity, and the filtering discs are arranged in the filter cavity in batches, so that the contact area with flue gas is enlarged, the flue gas is filtered and purified more effectively, filtrate on the surfaces of the multiple filter strips interacts with the flue gas, the flue gas in the filter cavity is comprehensively purified, the purification effect is guaranteed, and the practicability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of vacuum filters, more specifically, the invention relates to a flue gas filtering and purifying device for a vacuum filter. Background technique [0002] Vacuum filter is a large-scale filtering equipment capable of continuous operation. It has the outstanding characteristics of large flow, high-precision filtration, and easy automatic control. Its filtering capacity can be used for a single machine or for a certain area. It is widely used. In the fields of metallurgy, coal, sewage treatment, metal cutting, bearing manufacturing, automobile manufacturing and other fields, the current filtering equipment ranges from simple top-mounted core filters to large multi-pole filtering stations. The filtering situations are various, but there are The common problem is that it can only be used in a narrow range of small volume, small flow, and incapable of continuous work. For the emulsion circulation filtration of t...

[0002] Vacuum filter is a large-scale filtering equipment capable of continuous operation. It has the outstanding characteristics of large flow, high-precision filtration, and easy automatic control. Its filtering capacity can be used for a single machine or for a certain area. It is widely used. In the fields of metallurgy, coal, sewage treatment, metal cutting, bearing manufacturing, automobile manufacturing and other fields, the current filtering equipment ranges from simple top-mounted core filters to large multi-pole filtering stations. The filtering situations are various, but there are The common problem is that it can only be used in a narrow range of small volume, small flow, and incapable of continuous work. For the emulsion circulation filtration of the rolling mill system used by large metallurgical enterprises, the cutting fluid circulation filtration of machinery manufacturing plants, etc., these conventional filters are dwarfed by

[0003] However, when the existing technology vacuum filter is in use, the effect of filtering and purifying the flue gas is poor, and it cannot meet the requirements of comprehensive purification. It is not easy to replace the filter device, which reduces the practicability of the device, and The heat generated by the waste heat of the flue gas is also wasted
