The invention provides a purifying system for a welding fume and relates to an environment-friendly de-dusting technique. The technical problem that the welding fume generated in the present welding process is harmful to human body and pollutes the environment can be solved. The purifying system comprises a plurality of moveable arm hoses, an air exhausting main pipeline, an adsorbing tower, a connecting pipe, a centrifugal fan and a vertical exhausting pipe, wherein the moveable arm hoses are hung in a welding chamber; the air exhausting main pipeline is arranged on the upper part of the welding chamber; the adsorbing tower, the connecting pipe, the centrifugal fan and the vertical exhausting pipe are arranged on the outer side of the welding chamber; exhaust ports of the moveable arm hoses are connected with the air exhausting main pipeline; the air exhausting main pipeline is connected with the adsorbing tower through the connecting pipe; the adsorbing tower is connected with the centrifugal fan; an air outlet of the centrifugal fan is connected with the vertical exhausting pipe; the air outlet of the vertical exhausting pipe is connected with the atmosphere; electric valves arearranged on the moveable arm hoses close to the air outlet. The purifying system is used for purifying the fume in the welding chamber and has the advantages of simple structure, economic and applicable effects, capability of effectively reducing the direct harm of the welding fume to the worker and capability of reducing the atmospheric pollution.
Description
technical field [0001] The invention belongs to the technical field of environmental protection and dust removal, and in particular relates to a welding fume purification system. Background technique [0002] Welding is an essential and important process in the manufacturing process of steel structure parts. A large amount of fume will be produced during the welding process, and the welding fume contains Fe 2 o 3 , SiO 2 , MnO, HF (hafnium), CO, CO 2 , O 3 ,NOX,CH 4 Welders can easily cause occupational diseases such as pneumoconiosis and manganese poisoning, and the discharge of welding fume into the atmosphere will cause air pollution. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the prior art, provide a welding fume purification system, and solve the technical problems that the welding fume generated in the existing welding process will harm the human body and pollute the environment. [0004] The pre...
