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.

[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 workpieces requires special hoisting equipment, and the logistics is complicated

[0003] The treatment methods for dealing with welding fumes in the existing industry include: 1. Local ventilation and dust removal methods, which are greatly restricted by site layout, operator habits and equipment movement space; the protection objects are limited to welding workers, and the entire workshop environment cannot be improved; space requirements The laying of pipelines is limited by the conditions of the factory building. If the existing pipelines are in charge, it is difficult to realize the installation of this system; the workload of the workers is increased. When the position of the welding point changes, the workers need to move the suction hood to be effective; 2 1. Replacement ventilation method, this method requires that the indoor wind speed cannot be arbitrarily small, and it increases with the increase of air volume and cooling load; due to the limitation of thermal comfort conditions, it is actually impossible to produce a squeeze similar to plug flow indoors flow; plug flow and squeeze flow similar to plug flow will only appear in the field of purification air conditioning; the overall ventilation is large and the energy consumption is large

Dust is easy to stay, and the problem of dust removal cannot be completely solved; the essence of the system is to dilute the smoke concentration in the room through supplementary fresh air, and it cannot be treated from the source; 3. Replacement ventilation method, which requires continuous supply of high-pressure fresh air, energy consumption Large, high operating costs, high one-time investment; large-area blowing and air supply, inconvenient to control, high airflow organization requirements in the plant
