Problems solved by technology

[0004] At present, when dealing with particulate matter in industrial waste gas, it is usually filtered by a filter to reduce the possibility of particulate matter being discharged into the air, but in the actual purification process, the possibility of the filter screen being blocked is prone to occur, thus hinder the purification of exhaust gas

Abstract

The invention discloses a pneumatic typethermal blockage dredging filter screen based on waste gas and dust purification, and belongs to the technical field of waste gas purification. According to thescheme, when a first filter screen is blocked, the air pressure on the left side of the first filter screen can be gradually increased, so that part of waste gas is promoted to fully react with reductive iron powder, and therefore, the temperature of a memory alloy spring increases, metal blockage dredging fiber ropes are pushed to move rightward to break granular materials accumulated on the left side of the first filter screen; when the waste gas enters an air impact balloon, a pneumatic rotating plate can be promoted to rotate, so that a built-in air bag ball is driven to rotate; along with the rotation of the built-in air bag ball, ferric ferrous oxide obtained after reacting reductive iron powder and oxygen is adsorbed, the reaction between oxygen in the waste gas and the reductive iron powder can be promoted by means of swing of thepneumatic rotating plate, so that the heat production efficiency is improved; and after the temperature is reduced, the memory alloy spring is promoted to recover to the low-temperature phase state thereof, so that the metal blockage dredging fiber ropes are dragged to reset.

Description

technical field [0001] The invention relates to the technical field of exhaust gas purification, and more specifically relates to a pneumatic heat flow resistance filter screen based on exhaust gas dust purification. Background technique [0002] Exhaust gas refers to the toxic and harmful gases emitted by human beings in the process of production and life, especially the production and emission of domestic waste gas from chemical plants, steel plants, pharmaceutical factories, coking plants and oil refineries, and human life. Strong odor, serious environmental pollution and impact on human health Exhaust gas contains many types of pollutants, its physical and chemical properties are very complex, toxicity is not the same, fuel combustion exhaust gas contains sulfur dioxide, nitrogen oxides (NOx), hydrocarbons Compounds, etc.; due to the different raw materials and processes used in industrial production, various harmful gases and solid wastes are discharged, containing vari...
