Description

An integral workshop air purification device with a retractable suction and air supply structure

technical field

The invention relates to the technical field of air purification, in particular to an integral workshop air purification device with a retractable suction and air supply structure, which is suitable for indoor interference in workshops and requires local environmental control.

Background technique

Industrial environmental gas pollution is one of the most prominent environmental problems of occupational health in the current industrial production process in my country. A large number of industrial production processes such as welding, grinding, casting, etc. pollute the ambient gas, which reduces the indoor environmental quality of industrial plants, brings serious harm to human health, and causes huge losses to the national economy.

With the rapid development of my country's national economy and the rapid development of industrial manufacturing, the impact on the production environment is increasing. A large amount of harmful fumes will be generated during welding on site. These fumes contain iron oxide, manganese oxide, and fluoride. And other toxic metal oxides, it is very easy to harm the human respiratory system, skin, eyes, blood, etc. Welding fume is formed by the condensation of metal and metallurgical reactant vapors evaporated from the welding area away from the welding area, and exists in the form of aerosol. The steam condenses into primary particles near the welding area, and the primary particles condense into secondary particles as the temperature decreases, and then diffuse out in a certain way. On-site grinding, especially in the production workshop of related processes such as grinding and polishing of FRP products, will produce a large amount of dust particles and harmful substances. These harmful substances are suspended in the room under the action of the thermal plume, which seriously affects the health and work of the staff. Emotions must be managed according to national labor protection regulations and relevant health standards. The governance of the operating environment has always been the goal and direction of our efforts.

At present, there are two main types of air treatment methods for harmful substances in industrial workshops: one is point-to-point local treatment, which uses a single dust collector for each pollution source such as welding points, grinding stations, and stations that generate dust and exhaust gas, or Connect all work stations and treat them with a large dust collector. The local dust removal method is directly aimed at the high-concentration discharge area of welding fume, which has remarkable effect and saves investment. Disadvantages: limited by the site layout, operator habits and mobile station space, the capture effect of waste gas is not good and the treatment effect cannot be achieved. The second type is the overall plant management. The air containing smoke and dust enters the smoke and dust purification equipment through the return air pipeline through the layered air supply air flow organization. The poor air density results in a bottom-up ventilation airflow in the room. The treated air flows out from the air distributor at a very low flow rate, and is slowly raised by the updraft of the heat source, the push of the subsequent fresh air and the suction of the exhaust port, forming an upward unidirectional flow similar to a piston flow. Therefore, the hot and stagnant indoor air is lifted to the top of the workshop by the subsequent fresh air and exhausted by the air outlet arranged in the upper part.

In terms of method, the overall treatment effect is good, but the investment is large and the operating cost is high, and some factories are not suitable for closing, and some are air pollution in sub-regional areas. Therefore, to solve the problems that cannot be solved by point-to-point local governance, as well as the difficulties encountered in overall plant governance, an innovative technology is needed to achieve the goal.
