Industrial energy-saving and environment-friendly flue gas cleaning device

Abstract

The invention relates to the technical field of flue gas cleaning equipment and discloses an industrial energy-saving and environment-friendly flue gas cleaning device. The industrial energy-saving and environment-friendly flue gas cleaning device comprises a flue gas feeding pipe; a guide plate is fixedly arranged on one side of the top of an inner chamber of the flue gas feeding pipe; a purifying tank is arranged on one side of the flue gas feeding pipe; a connecting pipe is fixedly sleeved on one side of the bottom of the flue gas feeding pipe; a filter screen is fixedly sleeved on the topof the inner chamber of the connecting pipe; a scraper blade located above the filter screen is moveably sleeved on one side of the inner chamber of the connecting pipe. In the industrial energy-saving and environment-friendly flue gas cleaning device, a gas concentration detection device is arranged on a flue gas discharging pipe and is used for detecting content of toxic and harmful gases in thepurified flue gas. When the effect of purifying flue gas is unsatisfactory, a second solenoid valve is opened and a fan is started to extract purified flue gas and convey into the flue gas discharging pipe, and then the purified flue gas passes by a first purifying chamber and a second purifying chamber for circular purifying treatment, so that the purifying effect of the glue gas is promoted andthe environment protection is benefited.

Description

technical field [0001] The invention relates to the technical field of flue gas purification equipment, in particular to an industrial energy-saving and environment-friendly flue gas purification device. Background technique [0002] Industrial smoke refers to the dust containing pollutants that is discharged into the atmosphere during the fuel combustion production process in the factory area, often containing various metals, non-metallic fine particles, and harmful gases of sulfur dioxide, nitrogen oxides, and hydrocarbons. The diameter of dust particles < 0.19mm is often produced by the combustion process, called "suspended particles", which are in an irregular Brownian motion state, but the particles can be enlarged through collision and condensation, which seriously pollutes the environment, affects air quality, and endangers Human health, so certain measures must be taken to control it. Commonly used dust removal devices include mechanical, filter, washing, and elec...

Problems solved by technology

[0004] The invention provides an industrial energy-saving and environment-friendly flue gas purification device, which has the advantages of good dust filtering effect and good flue gas purification effect, and solves the problem that the existing industrial flue gas purification device usually filters the dust in the flue gas by setting a filter net , the way of filtering with filter screen is not only easy to block during use and affect the filtering effect, but also the filter screen is not easy to clean and replace, and at the same time, the dust in the flue gas is filtered through the filter screen, the filtering effect is poor, and The existing industrial flue gas purification devices cannot detect the purified flue gas, it is difficult to ensure the purification effect of the flue gas, and at the same time, it is impossible to circulate and purify the unsatisfactory flue gas, which is easy to cause pollution to the environment
