Blowing and inhaling type welding fume dust removal system

Abstract

The invention relates to a welding fume dust removal system and especially relates to a blowing and inhaling type welding fume dust removal system. For solving the problems that the welding fume is small in particle size, welding work stations are large in number, welding work pieces are large in size, and the welding fume is difficult to capture, the invention provides the blowing and inhaling type welding fume dust removal system, which utilizes jet flow as power and transports harmful substances, such as the welding fume, to an air suction port; and then the welding fume is filtered and discharged through an electrostatic dust remover. In addition, diffusion of the harmful substances, such as the welding fume, is inhibited and controlled by the jet flow. The system integrates both air flow blowing and inhalation, wherein the air blowing port is arranged opposite to the air suction port to form blowing and inhaling air flow, which is used for inducing, controlling and filtering the air flow of the harmful substances, such as the welding fume.

Description

technical field [0001] The invention relates to a welding fume dedusting system, in particular to a blowing and suction type welding fume dedusting system. Background technique [0002] The treatment of welding fume is a comprehensive problem. The difficulty lies in: 1. The particle size of welding fume is small, and its particle size is 0.01-10um, so it is difficult to filter and purify; 2. The variability of welding stations, many welding stations, welding The large workpiece makes it difficult to capture welding fume; 3. The welding workpiece has large dimensions and large welding area, making it difficult to capture welding fume; 4. There is a maximum concentration zone of fume in the welding workshop, and it is difficult to remove dust with common ventilation technology; 5. Welding with oil fume It is very difficult to purify smoke and dust; 6. Auxiliary equipment takes up a lot of space, and various pipelines are full of workshops; 7. The loading and unloading of workp...
