Safety protection device for dust removal system

Abstract

The invention relates to the technical field of dust removal, and discloses a safety protection device for a dust removal system. The safety protection device comprises an inner cylinder, wherein the side surface of the upper part of the inner cylinder is provided with an air inlet, the periphery of the inner cylinder is provided with an outer cylinder, and the inner cylinder and the outer cylinder are coaxially assembled. According to the invention, inert cooling gas is used for cooling the inner cavity of the inner cylinder, heat in the inert cooling gas is absorbed by heat absorption liquid under fixed duration, and the temperature of the inner cylinder is measured according to the expansion size of the volume of the heat absorption liquid; and the pushing effect of a push rod on a gas distribution plug and the shielding effect of the gas distribution plug on a dusty gas outlet and a inert cooling gas outlet are matched, so the gas inlet amount of dusty gas and the gas inlet amount of inert cooling gas are kept balanced, the purpose of ensuring that the temperature of the inner cavity of the inner cylinder is within a safe range is achieved, the possibility of explosion is reduced, and safety protection effect in a dust removal process is improved.

Description

technical field [0001] The invention relates to the technical field of dust removal, in particular to a safety protection device for a dust removal system. Background technique [0002] With the progress and development of industry, the production and manufacturing of metal products is often accompanied by the generation of metal dust. Metal dust permeates in the air and is easy to cause harm to the human body. Therefore, it is necessary to use a dust collector to collect the dust. For some metal dust such as aluminum, magnesium powder, etc., the reaction with water will make the combustion more intense, so wet dust collectors cannot be used, only dry dust collectors can be used, and cyclone dust collectors are commonly used. The principle of the cyclone dust collector is to make the dust-laden air flow rotate, and the dust particles are separated from the air flow by centrifugal force and collected on the wall of the device, and then the dust particles fall into the dust co...

Problems solved by technology

[0005] Aiming at the deficiencies in the use of the existing safety protection device proposed in the background technology, the present invention provides a safety protection device for dust removal system, which has the functions of reducing dust cloud, dynamically balancing the intake air volume of gas and dynamically controlling the dust collector. The advantage of the temperature in the middle solves the problems of low safety protection effect and easy failure of the protection device proposed in the above background technology.
