Energy-saving flue gas continuous dedusting device

Abstract

The invention discloses an energy-saving flue gas continuous dedusting device. The energy-saving flue gas continuous dedusting device comprises a shell and a cloth bag, wherein the lower end of the left side of the shell is communicated with a flue gas inlet pipe; a conical barrel is arranged in the shell; baffle plates are uniformly distributed on the inner wall of the conical barrel; a first cross plate is located above the conical barrel in the shell; a central ventilating hole is formed in the central position of the first cross plate; the upper end of the conical barrel is communicated with the central ventilating hole; the upper part of the central ventilating hole is communicated with a dedusting cloth bag. According to the energy-saving flue gas continuous dedusting device disclosed by the invention, dust on the inner wall of the cloth bag can be cleaned through a scraping disc provided with a screw rod for driving and through up-and-down reciprocating movement of the scrapingdisc, and a filter effect of the cloth bag is ensured; compared with a traditional back pulse jet cleaning device, reduction of the treatment ability due to shut down can be avoided, and continuous operation can be realized; through the arrangement of a heat exchange pipe, heat of flue gas can be efficiently recycled, and energy saving and high efficiency are realized; through the arrangement of the conical barrel provided with the baffle plates, large-sized dust in the flue gas can be efficiently removed, small-sized dust can be conveniently removed by the cloth bag later, and the treatment efficiency is increased.

Description

technical field [0001] The invention relates to the field of energy-saving equipment, in particular to an energy-saving flue gas continuous dust removal device. Background technique [0002] The bag filter is a dry dust filter device. It is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-woven felt, and uses the filter function 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] When the traditional bag filter is cleaning the bag, it is necessary to close the operation of the bag in the area to be cleaned, and then use pulse back blowing. , which reduces the processing capacity of the dust collector, except that the general industrial waste gas contains a lot of heat, which is directly di...
