Integral welded-type vertical multi-filter drum dust remover

Abstract

The invention discloses an integral welded-type vertical multi-filter drum dust remover. The dust remover comprises a rack and a dust removing box, wherein the dust removing box is disposed on the rack and is provided with a dust inlet and an air outlet. A back flushing control device which acts on filter drums to blow off dust accumulated on the surfaces of the filter drums is disposed in the dust removing box. The back flushing control device comprises a gas storing bag disposed outside the dust removing box, a high-pressure air injection pipe extending into the filter drums, and a magnetic valve controlling gas fluid on-off. The high-pressure air injection pipe is connected to the air storing bag through the magnetic valve. The filter drums are arranged from the center of the smoke and dust filtration area to the outside in a radiation shape. The central axes of the filter drums are parallel to the axis of rotation of the smoke and dust filtration area. The plurality of the filter drums are disposed vertically in a multi-layer manner, thus enhancing the filtration and dust removing effects largely.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an integral welded vertical multi-cartridge dust collector which can be widely used in chemical industry, electronics, metal processing, pharmaceutical, food processing, automobile and other industries at the same time. Background technique [0002] Welding fume is a very complex substance. More than 20 elements have been found in the fume, among which Fe, Ca, Na, etc. are the most abundant, followed by Si, Al, Mn, Ti, Cu, etc. The main harmful substances in welding fume are Fe2O3, SiO2, MnO, HF, etc. Among them, Fe2O3 is the most abundant, generally accounting for 35.56% of the total amount of fume, followed by SiO2, whose content accounts for 10-20%, and MnO accounts for 5-20%. %about. [0003] During metal welding, a large amount of smoke and dust is suspended in the working environment. These smoke and dust are inhaled into the human lungs, which will seriously affe...

AI Technical Summary

Problems solved by technology

In order to eliminate the particles in the smoke and dust, a filter device can usually be added before the adsorbent. Although this composite device can purify the smoke and dust, the filter has a large resistance and needs to be driven by a high-pressure fan. The efficiency is low, and the adsorbent is no longer troublesome.
