A plasma asphalt flue gas purification device

Abstract

The invention discloses a plasma asphalt flue gas purification device, which comprises a purification body, a centrifugal separation chamber, a plasma purification chamber, a corona rod adsorption chamber and a fabric adsorption device. By installing the fabric adsorption device inside the adsorption chamber, the first fabric filter The net is made of acrylic needle-punched felt material, which can absorb the particles in the flue gas. At the same time, the second fabric filter is made of polytetrafluoroethylene glass cloth material, which can absorb the chemical substances in the flue gas. The third fabric filter The use of ultra-fine fiber needle-punched non-woven fabric materials can separate fine particles of 0.1 to 10 microns, and filter the flue gas step by step through three layers of different filters, so that the flue gas can be purified more thoroughly, which solves the problem of existing purification devices , the problem of incomplete purification of particulate matter in the flue gas, and the sealing structure designed on the rear end of the drawing plate, the first sealing strip and the second sealing strip are respectively embedded inside and outside the sealing ring body, reducing the gap between the drawing plate and the adsorption chamber. The gap increases the sealing.

Description

technical field [0001] The invention relates to the related field of asphalt fume purification, in particular to a plasma asphalt fume purification device. Background technique [0002] In the production process of the asphalt mixing plant, it is necessary to heat and mix the asphalt raw materials. During this process, a large amount of asphalt fume will be generated. The flue gas contains a variety of organic substances, including carbocyclic hydrocarbons and cyclic hydrocarbon derivatives. Many of them are harmful to human health. Therefore, it is very necessary to purify the asphalt fume so that the discharge meets the atmospheric environmental standards. , high-energy electron radiation, ultraviolet light decomposition and other technologies work together to break the macromolecules in the asphalt fume into small molecules, and then decompose them, which can effectively purify the asphalt fume. [0003] However, the existing purification devices have the following probl...

Problems solved by technology

[0008] The present invention provides a plasma asphalt flue gas purification device through improvement. By installing a fabric adsorption device inside the adsorption chamber, the first fabric filter screen is made of acrylic needle-punched felt material, which can adsorb the particulate matter in the flue gas. At the same time, the second The second fabric filter is made of polytetrafluoroethylene glass cloth material, which can absorb radioactive particles and chemical substances in the smoke, and the third fabric filter is made of ultrafine fiber needle-punched non-woven fabric material, which can separate 0.1 to 10 microns The fine particles in the flue gas are filtered step by step through three different filter screens, so that the flue gas can be purified more thoroughly, which solves the problem of incomplete purification of the particulate matter in the flue gas by the existing purification device. The sealing structure designed on the end face is embedded inside and outside the sealing ring through the first sealing strip and the second sealing strip, which reduces the gap between the drawing plate and the adsorption chamber and increases the sealing performance; by installing a sliding member at the bottom of the bottom plate, its The slide bar is installed at the bottom of the base plate. By sliding on the inside of the slide rail, the base plate drives the three filter screens to be pulled out. Purification device, the filter parts will adhere to a lot of dirt after a long time of filtering work, it is not easy to disassemble when it needs to be replaced, and it is troublesome to replace
