Embodiment 1

[0013] A portable smoke and dust water bath treatment machine, which consists of: a vacuum cleaner 1, characterized in that: the front end of the vacuum cleaner has a connecting pipe 2, the connecting pipe has a polymer filter cotton 3, and one end of the connecting pipe is connected to a water container 4, The water container is filled with an active aqueous solution 5, and the bottom end of the water container is connected with a U-shaped pipe 6 with an upward opening.

Embodiment 2

[0015] According to claim 1, the portable smoke and dust water bath processing machine is characterized in that: the connecting pipe 2 is provided with a polymer filter cotton 3, and the bottom of the connecting pipe is the described water container 4; There is an active aqueous solution 5; the bottom end of the container is connected with a U-shaped tube 6 with an upward opening.

Embodiment 3

[0017] A purification method using the portable welding fume water bath processing machine described in claim 1 or 2, characterized in that: the smoke generated during the welding process is collected by the opening section of the U-shaped pipe in the front section of the processing machine during use, and the collected The flue gas is pumped into the water container containing the active aqueous solution by the negative pressure generated by the vacuum cleaner. Before the welding fume is pumped into the water container, the flue gas fully contacts with the active aqueous solution in the U-shaped tube, so that the welding fume Toxic particles and gases are fully dissolved in the aqueous solution, and the polymer filter cotton can block the splashing water in the water container, thereby preventing the aqueous solution from entering the motor, and can achieve secondary filtration of the welding fume, greatly improving the filtration efficiency.

Abstract

The invention discloses a portable water bath purification device for welding flue gas and a purification method. General prior purification methods for waste gas generated by welding comprise an electrostatic method, a spray dust removal method and a cloth bag dust removal method, and the purification efficiency of the methods is low, and the cost is high. The purification device provided by theinvention comprises a dust collector (1), and is characterized in that the front end of the dust collector is provided with a connecting pipe (2), a high-molecular filtration cotton (3) is arranged inthe connecting pipe; one end of the connecting pipe is connected with a water container (4); the water container contains an active aqueous solution (5), and the bottom end of the water container isconnected with an U-shaped pipe (6) with upside open. The purification device and purification method provided by the invention are used for flue gas purification.

Description

technical field [0001] The invention relates to a portable welding fume water bath processing machine and a purification method. Background technique [0002] At present, most of the waste gas generated by welding is directly discharged into the atmosphere, which has caused a huge irreversible impact on our living environment and health. The composition of the flue gas generated by welding is complex. The more common purification methods at this stage are electrostatic method, spray dust removal method and bag dust removal method. These methods have certain adsorption and purification effects on the fume generated by welding, but the purification efficiency is low. , and the cost is also very high. Contents of the invention [0003] The object of the present invention is to provide a portable welding fume water bath processing machine and purification method. [0004] Above-mentioned purpose realizes by following technical scheme: [0005] A portable smoke and dust wate...
