Gasoline odor adsorption and purification apparatus

Abstract

The invention provides a gasoline odor adsorption and purification apparatus. The gasoline odor adsorption and purification apparatus comprises an air bellow filter screen, positioning plug boards, aplug bush, an air draft tube, a fan downward sliding track, a fan and a fan downward sliding support, wherein four fan cover positioning plug boards are circularly welded on the oblique circumferential outer wall of an exhaust hood in a penetrating manner, and the top ends of the four fan cover positioning plug boards extend upwardly in a supporting manner and are provided with one downward sliding limiting board; a top-end active carbon filter screen is circularly arranged, four filter screen supporting plug boards are circularly welded on the circumferential outer wall of an annular supporting framework of the top-end active carbon filter screen in an array manner, a rectangular plug hole is formed on each filter screen supporting plug board in a penetrating manner, and the top-end active carbon filter screen is arranged on the four fan cover positioning plug boards by virtue of the four filter screen supporting plug boards and urges the top ends of the four downward sliding limitingboards. By arranging the four fan cover positioning plug boards, the four fan cover positioning plug boards not only have a downward sliding positioning function when the exhaust hood is assembled ina plugging manner, and also have a function for pressing and positioning the fan.

Description

technical field [0001] The invention belongs to the technical field of gasoline adsorption equipment, and more specifically relates to a gasoline odor adsorption and purification device. Background technique [0002] Gasoline is mainly used as a power fuel for transportation vehicles. Rubber, paint, dye, printing, pharmaceutical, adhesive and other industries use gasoline as a solvent. The cleaning and decontamination of machine parts and clothing and the pretreatment of electroplating products use gasoline as a degreasing agent. Due to different origins and production methods, the composition and toxicity of gasoline vary. Gasoline is highly volatile and easily soluble in fat. In the production environment, it is mainly inhaled into the human body through the respiratory tract in the form of vapor, and then circulates through the blood to the human brain, causing anesthesia. It also has toxic effects on the central nervous system and peripheral nerves, and also has adve...

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a gasoline odor adsorption and purification device to solve the inconvenience of pushing and transferring the existing gasoline adsorption device, and the suction position is relatively single, which causes the suction and filtration efficiency of the surrounding air to be too low to be relatively fast. The air in a certain part of the working area inside the factory building is purified, and the cleaning operation process of the ventilation channel is relatively cumbersome. In addition, it is inconvenient to disassemble and take out the fan, which makes it difficult to clean the fan blades.
