Device used for tin soldering flue gas purification

Abstract

The invention discloses a device used for tin soldering flue gas purification. The device comprises a purification box (1), a gas inlet pipe (2) penetrating through a top plate of the purification box (1)to extend into the purification box (1), and at least one gas outlet pipe (3) communicated with the purification box (1), wherein the outer wall of the gas inlet pipe (2) is hermetically connected with the top plate of the purification box (1); the end surface of the gas outlet end of the gas outlet pipe (2) is inwards recessed to form a recessed cavity (2.1); the outer wall of the gas inlet pipe (2) surrounds the cavity wall of the recessed cavity (2.1) to form a cavity (2.2); and a plurality of gas outlets are formed in the cavity wall of the recessed cavity (2.1). The device has the advantages that the device can be miniaturized, the purification efficiency is high, the device is maintained conveniently, the use is simple, and the device is environment-friendly and energy-saving.

Description

technical field [0001] The invention relates to the technical field of environmental protection purification equipment, in particular to equipment for purifying solder fume. Background technique [0002] The smoke generated by the solder wire during welding is due to the gasification of the flux in the solder wire when it meets the high-temperature electric soldering iron. These suspended smoke and odorous gases not only directly affect the health of the staff, but also seriously affect the air quality. , destroying the ecological environment, and at present, the mechanical equipment used in the treatment of solder fume is relatively lacking, or the work performance is relatively simple, generally the principle of directly using the fan to absorb the solder fume through the filter, this is not only because The limited adsorption capacity of the filter makes it troublesome to replace the filter frequently, and because the air permeability of the filter is poor, the filter tha...

[0002] The smoke generated by the solder wire during welding is due to the gasification of the flux in the solder wire when it meets the high-temperature electric soldering iron. These suspended smoke and odorous gases not only directly affect the health of the staff, but also seriously affect the air quality. , destroying the ecological environment, and at present, the mechanical equipment used in the treatment of solder fume is relatively lacking, or the work performance is relatively simple, generally the principle of directly using the fan to absorb the solder fume through the filter, this is not only because The limited adsorption capacity of the filter makes it troublesome to replace the filter frequently, and because the air permeability of the filter is poor, the filter that is too thick will seriously affect the purification efficiency of the equipment, and the filter that is too thin will greatly reduce the adsorption effect, and At present, this type of equipment cannot maintain high purification efficiency and miniaturized equipment for home amateurs. Therefore, a miniaturized, high purification efficiency, easy maintenance, easy to use, environmentally friendly, and energy-saving equipment for soldering fume is designed. Purification equipment has become an urgent problem to be solved in industrial production and sustainable development
