In order to solve the above-mentioned problems, the technical solution adopted by the utility model is: a numerical control plasma cutting machine random linkage wet smoke removal purification device, including a gantry support and a liquid pool, a venturi tube and a filter box arranged on the gantry support, the venturi The upper part of the inner tube is the suction port, which is connected to the shroud through the telescopic tube. The shroud is set at the cutting nozzle and linked with the cutting nozzle; There is a drain valve at the bottom of the pool, and a circulating pump is installed outside the pool. The liquid inlet pipe of the circulating pump is connected with the liquid pool. A liquid outlet pipe extends into the inside of the Venturi tube, and a first nozzle is arranged at the end thereof, a second liquid outlet pipe extends into the inside of the filter box, and a second nozzle is arranged at the end, and a fan is arranged on the upper part of the filter box, An air outlet is arranged on the filter box, and a filler separator is arranged in the filter box below the second nozzle.

As a preferred solution, a demister is arranged above the second spray head in the filter box.

As a preferred solution, a filter is arranged above the demister in the filter box.

The beneficial effects of the utility model are: the random linkage wet smoke removal and purification device of the above-mentioned numerical control plasma cutting machine has a simple structure, convenient installation, modular design and assembly, and a beautiful appearance. The telescopic tube is connected to the suction port of the equipment, so that it can be randomly linked to collect the smoke generated by the cutting nozzle during cutting. In addition, through the double treatment of the Venturi tube and the filter box, the sedimentation and separation efficiency of the smoke and dust is greatly improved, and the filter unit is not blocked.
