Multi-stage dust, waste gas and solid particulate matter purification device

Abstract

The invention discloses a multi-stage dust, waste gas and solid particulate matter purification device, which comprises a gas inlet pipe, a first-stage filtering system, a gas feeding pipe, a second-stage filtering system, a second gas feeding pipe and a third-stage filtering system, and has the beneficial effects that dust and waste gas are effectively filtered and adsorbed so as to ensure the purification effect, multi-stage adsorption purification is performed so as to prolong the service life and improve the purification efficiency, and multiple groups work simultaneously so as to effectively prevent unstable internal air pressure caused by blockage and ensure the operation safety.

Description

technical field [0001] The invention relates to the related technical field of waste gas treatment, in particular to a multi-stage dust waste gas solid particle purification device. Background technique [0002] Air pollution, also known as air pollution, according to the definition of the International Organization for Standardization (ISO), air pollution usually refers to: due to human activities or natural processes, some substances enter the atmosphere, present a sufficient concentration, and reach a sufficient time. Phenomena that are thereby detrimental to the comfort, health and welfare of humans or the environment. [0003] In other words, as long as the quantity, nature and time of existence of a certain substance are sufficient to affect human beings or other organisms and property, we can call it an air pollutant; and the phenomenon caused by its existence is air pollution. [0004] Generally, there are many solid particles in the dust-type exhaust gas, and when ...

AI Technical Summary

Problems solved by technology

[0008] In order to overcome the general dust-type exhaust gas in which there are many solid particles, when the aperture of the orifice of the purification device is large, the purification effect will be deteriorated, and when the aperture of the orifice is small, the phenomenon of clogging will occur in a short period of time. Inconvenient, at the same time, adsorption-type purification devices also need to frequently replace the adsorption plate, which is extremely inconvenient to use. The present invention provides the following technical solutions: including air intake pipe, primary filter system, air supply pipe, secondary filter system, the second Two-stage air supply pipe, three-stage filter system;
