Welding fume and how to control the damage

There are two ways to control the welding fumes and harmful gases in the way of transmission: overall ventilation and local exhaust. The overall ventilation, also known as dilution ventilation, is to dilute the concentration of harmful substances in the indoor air with clean air so that the concentration of harmful substances in the indoor air does not exceed the allowable concentration specified by the sanitary standard, and continuously discharge the polluted air to the outside or collect and purify. Overall ventilation includes two modes: natural ventilation and mechanical ventilation. In foreign countries, natural ventilation is generally used for outdoor welding operations or open space welding, and mechanical ventilation is usually used for indoor work. Through the axial flow fan installed on the wall or ceiling, the welding fumes in the workshop are discharged to the outside, or purified by the purifier and recycled in the workshop to reduce the concentration of soot in the workshop. The cycle of purified air solves the energy loss in the workshop, which is widely used abroad.
1. It can be flexibly moved to any position of the factory building, and is not subject to the constraint that the dusting point is not fixed.
2. The equipment is equipped with universal casters to facilitate the positioning of the equipment.
3. Satisfactory treatment efficiency, under the rated treatment air volume, the dust purification rate is ≥99%, and the clean air discharged after treatment can be directly discharged in the workshop.
4, using filter-type purification method, Germany imported (PTFE) membrane filter material, high purification efficiency, low cost of consumables, no need to change frequently, saving environmental protection.
5, the device built-in automatic pulse cleaning device, to maintain a constant suction volume of the device, and a constant purification capacity. (can be selected according to requirements)
6. The control system of the equipment design is stable and equipped with high voltage leakage protection.
7. Use the universal suction arm to hover anywhere in the three-dimensional space and reach the dust point in any direction at 360 degrees.
8. Different working conditions can be selected according to the corresponding dust cover.
9. After shock absorption and noise reduction treatment, the noise and environmental protection of the equipment are guaranteed.
10. The equipment is easy to operate and easy to clean and maintain.
11. The pollution source can be processed by mobile single machine or multi-station centralized processing.
12, can be customized according to customer requirements. m.jl2e9.cn
