Dedusting method and device for high-temperature smoke

Abstract

The invention discloses a dedusting method for high-temperature smoke. The method comprises the steps that a dust collection cover is used for collecting the smoke, the smoke is conveyed to a purification dedusting system through a pipe for dedusting, and the concentration of combustible substances in the pipe is detected in real time; when the concentration exceeds a preset concentration range, first protective gas is supplemented for the interior of the pipe at a preset spraying angle, so that the concentration is restored to the preset concentration range; the temperature in the pipe is detected in real time, and when the temperature exceeds the preset temperature range, second protective gas is supplemented for the interior of the pipe, so that the temperature is restored to a preset temperature range; an expansion assembly is arranged on the pipe for compensating for deformation of the pipe. The invention further discloses a dedusting device for the high-temperature smoke. The device corresponds to the method. According to the method and device, the pipe can be effectively prevented from being damaged, smoke escape is avoided, and the device is safe to use.

Description

technical field [0001] The invention relates to the technical field of dust removal equipment, more specifically, it relates to a method and device for removing dust from high-temperature smoke and dust. Background technique [0002] High-temperature smoke and dust will be generated in metal smelting, chemical, pharmaceutical, casting or petroleum industry processing, which will seriously pollute the atmosphere and have a great impact on the occupational health of the working environment. In environmental protection requirements, employees' health and safety awareness will be improved. Under the premise, it is necessary to collect the dust generated by these industries to reduce pollution. [0003] The traditional method uses a hood to collect smoke and dust, and transports it to the purification and dust removal system through pipelines. During the transportation process, high-temperature smoke and dust have a great impact on the shape and structure of the pipeline, which m...

Problems solved by technology

[0003] The traditional method uses a hood to collect smoke and dust, and transports it to the purification and dust removal system through pipelines. During the transportation process, high-temperature smoke and dust have a great impact on the shape and structure of the pipeline, which may lead to desoldering and cracking of the middle welding part of the pipeline, serious deformation of the pipeline, and dust outside the pipeline. If there is CO in the pipeline, when the concentration of CO is greater than the safe range, an explosion may occur, resulting in a safety accident, resulting in material loss and personal injury
