An industrial boiler waste gas dedusting device

Abstract

The invention belongs to the technical field of de-dusting of boiler exhaust gas and particularly relates to a de-dusting device for industrial boiler exhaust gas. The de-dusting device comprises a de-dusting tank and a controller, wherein the de-dusting tank comprises a tank bottom of which the bottom is hollow; a water inlet and a gas outlet are formed in the upper end of the de-dusting tank; awater drainage pipe is arranged at the lower end of the de-dusting tank; an exhaust gas inlet penetrating through the tank bottom is formed in one end of the tank bottom and is communicated with the inner of the hollow tank bottom; the other end of the tank bottom is provided with an air vent; a reset spring and a sliding block are arranged in the tank bottom; an electromagnet is arranged in the sliding block; a spring tube and a sliding plate are arranged in the de-dusting tank; a magnet is arranged in the sliding plate; the magnet is adsorbed or disconnected by the electromagnet intermittently; the upper end of the spring tube is connected to the water inlet of the de-dusting tank; a plurality of sprayers are sequentially arranged on the pipe wall of the spring tube at intervals. The de-dusting device disclosed by the invention can cool the exhaust gas in the de-dusting process and can prevent dust in the exhaust gas from blocking other exhaust gas treatment equipment; meanwhile, damage of the exhaust gas with excessively high temperature to other equipment is avoided.

Description

technical field [0001] The invention belongs to the technical field of boiler waste gas dedusting, in particular to an industrial boiler waste gas dedusting device. Background technique [0002] Steel is a general term for iron-carbon alloys with a carbon content between 0.02% and 2.11% by mass. Humans have a long history of application and research on steel, but until the invention of the Bainite steelmaking method in the 19th century, the Production is a high-cost and low-efficiency work. Today, steel has become one of the most used materials in the world due to its low price and reliable performance. It is indispensable in the construction industry, manufacturing industry and people's daily life. By putting the pig iron for steelmaking into the steelmaking furnace and smelting it according to a certain process, the steel is obtained. At present, most of the steelmaking furnaces on the market are not equipped with dust treatment devices, but in the process of steelmaking, ...

Problems solved by technology

[0004] This technical solution humidifies the air entering the exhaust gas treatment box through the cooperation of water pipes, nozzles, and water tanks, so that the dust in the exhaust gas will increase in weight due to humidification, and has a dust removal effect. The upper end sprays downwards, which cannot cover the entire treatment box well and remove the dust in the exhaust gas, and the dust removal effect is not good
