Description
Technical Field
The invention relates to the field of welding fume treatment, in particular to a distributed plasma corona welding fume treatment system for a welding training center in colleges and universities.
Background
The fact that welding fume is not effectively treated by a welding workshop of a training center of colleges and universities is used as a heuristic, and the fact that welding fume is not effectively treated by a plurality of welding workshops of the training center of colleges and universities is investigated. The welding fume is solid particles which are formed in the production process and can float in the air for a long time, thereby affecting normal operation and seriously harming physical and psychological health of people.
With regard to prevention and control of welding smoke dust in a workshop, good working environment is created at home and abroad mainly from the aspects of ventilation and dust removal, welding process innovation, production equipment innovation and personal protection. The ventilation and dust exhaust is the most common measure for treating welding smoke dust and ensuring physical and psychological health of operators in a welding workshop, and is basically divided into two steps of capturing and purifying the welding smoke dust. The current measures of ventilation and smoke exhaust are mainly methods of point smoke exhaust, local ventilation, comprehensive ventilation and the like. Because the welding workshop is densely distributed, welding stations are variable, site workpiece transfer, traveling operation and other factors are limited in practical application. For a production workshop with large area and few operators, it is difficult and uneconomical to improve the ambient air of the whole workshop by local ventilation. The ventilation range of the overall ventilation is larger, and the required ventilation volume is larger. The existing three methods cannot give consideration to economy and environmental protection.
Therefore, a welding fume particle pollutant treatment device which can be used rapidly, efficiently and at low cost is needed to meet the requirement.
