Description

Technical Field

[0001] The utility model relates to the technical field of flue gas environmental protection treatment equipment, in particular to a flue gas environmental protection treatment device which can prevent particles from sticking. Background Art

[0002] Flue gas is a mixture of gas and smoke, and is the main cause of air pollution in residential areas. The composition of flue gas is very complex. Gases include water vapor, sulfur dioxide, nitrogen, oxygen, carbon monoxide, carbon dioxide, hydrocarbons, and nitrogen oxides, and smoke includes fuel ash, coal particles, oil droplets, and high-temperature cracking products. Therefore, flue gas pollution to the environment is a complex pollution of multiple poisons. The harm of smoke to the human body is related to the size of the particles. Most of the harm to the human body is caused by floating dust with a diameter of less than 10um, especially 1-2.5um floating dust, which is the most harmful. However, spray towers are often used in flue gas treatment.

[0003] However, the current spray tower has a single function and a relatively poor flue gas purification effect. It is also impossible to remove the adhesives on the inner wall of the spray tower, which affects the purification effect of the equipment. In addition, the replacement of the filter is troublesome, time-consuming and labor-intensive, affecting work efficiency, and is not worthy of widespread promotion and application.

[0004] For example, a flue gas environmental protection treatment device disclosed in Chinese patent CN212915137U, through the purification component set up, the purification liquid in the circulating water tank is brought into the annular tube through the circulating pump and sprayed out from the atomizing nozzle. It has a simple structure and is easy to operate. It has a good purification effect on the flue gas and prevents toxic gases from damaging the environment. The rotating component set up drives the stirring rod to rotate through the rotating motor, thereby driving the scraper to clean the inner wall of the spray tower body to prevent particles from sticking to it and affecting the normal operation of the equipment. The filter component set up has a simple structure and fixes the installation frame through the plug-in rod, which makes the installation and disassembly of the filter screen more convenient, saving time and effort, and worthy of wide promotion and application.

[0005] However, when the filter screen of the device filters the smoke, impurities in the smoke may clog the filter screen, thereby affecting the smoke filtering efficiency.

[0006] For this reason, we urgently need to provide a flue gas environmental protection treatment device that prevents particulate matter from sticking. Utility Model Content
