Decentralized cooling device for flue gas pipeline of bag type dust collector and implementation method of device

Abstract

The invention discloses a decentralized cooling device for a flue gas pipeline of a bag type dust collector and an implementation method of the device. The device comprises a connecting port, a flue gas conveying assembly and a cooling unit, a gas pipe connecting sleeve of the connecting port is installed at a flue gas exhaust port of a bag type dust collector, a sucking pump in the flue gas conveying assembly is started for sucking gas, hot flue gas in the bag type dust collector enters a gas conveying pipe in the flue gas conveying assembly through the connecting port and is conveyed upwards to a dispersing pipe, the flue gas enters a gas guide pipe in the cooling unit through the dispersing pipe, external circulating cooling water is introduced into a threaded pipe opening, the gas guide pipe is cooled through a cooling spiral pipe, the cooled flue gas enters the exhaust pipe and is filtered by a filter cavity and a filter screen of the exhaust pipe, and finally the cooled flue gas is discharged from an outer pipe connector, so that the flue gas of the bag type dust collector is quickly cooled, and the situation that the flue gas is directly discharged to scald workers or damage other equipment is prevented.

Description

technical field [0001] The invention relates to the technical field of bag type dust collectors, in particular to a decentralized cooling device for flue gas pipelines of bag type dust collectors and an implementation method thereof. Background technique [0002] The bag filter is a dry dust filter device, which is suitable for collecting 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 The action settles down and falls into the ash hopper. When the gas containing fine dust passes through the filter material, the dust is blocked and the gas is purified, and the temperature of the flue gas filtered by the bag filter is relatively high. If it is directly discharged after treatment, the external operator may be scalded, or the external equipment may be dama...

Problems solved by technology

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 The action settles down and falls into the ash hopper. When the gas containing fine dust passes through the filter material, the dust is blocked and the gas is purified, and the temperature of the flue gas filtered by the bag filter is relatively high. If it is directly discharged after treatment, it may burn the external operator or damage the external equipment. At present, there is no fast and effective flue gas cooling equipment for the bag filter.
