Improved bag-type dust remover

Abstract

The invention discloses an improved bag-type dust remover. The improved bag-type dust remover comprises a dust removal chamber; a plurality of dust removal textile cloth bags are arranged in the dustremoval chamber; a heat exchange chamber is arranged under the dust removal chamber; a heat insulation partition plate is arranged between the heat exchange chamber and the dust removal chamber; the bottom end of the side wall of the heat exchange chamber is provided with a high-temperature waste gas inlet and a circulating waste gas inlet; the top end of the side wall of the heat exchange chamberis provided with a low-temperature waste gas outlet; the bottom end of the side wall of the dust removal chamber is provided with a low-temperature waste gas inlet and a dust removal waste gas outlet; a sealed fan box is arranged outside the dust removal chamber; and the fan box is provided with an air inlet connected with the low-temperature waste gas outlet, a first air outlet connected with the low-temperature waste gas inlet, a second air outlet connected with the circulating waste gas inlet, and the like. The improved bag-type dust remover has a compact structure, heat collection and heat exchange functions are integrated, high-temperature waste gas can be rapidly cooled to a preset temperature, and then the high-temperature waste gas is fed into a bag-type dust collector, so that the use range of the bag type dust collector is expanded, waste gas heat energy is fully utilized, economic benefits of enterprises are improved, environment is protected better, and more energy is saved.

Description

technical field [0001] The invention relates to the technical field of industrial dust removal equipment, in particular to an improved bag filter with novel design and wide application range. Background technique [0002] The bag filter is a dry dust filter device, which is suitable for collecting fine, dry, non-fibrous dust, and is widely used in chemical technology fields such as industrial boiler exhaust gas dust removal, domestic or medical waste incineration, and metallurgy. The filter bag is generally made of textile filter cloth or non-woven felt, and uses the filtering effect of the fiber fabric to filter the dusty gas. When the dusty gas enters the bag filter, the dust with large particles and large specific gravity will When the air containing fine dust passes through the filter material, the dust will be blocked and the air will be purified. [0003] However, when the filter bag of the bag filter is made of textile cloth, it cannot be used to filter high-temperat...

AI Technical Summary

Problems solved by technology

[0003] However, when the filter bag of the bag filter is made of textile cloth, it cannot be used to filter high-temperature exhaust gas, so it greatly limits the scope of use and needs to be improved.
