Welding fume purifier workshop dust elimination manufacturer detailed parameters

Research on purification methods for smoke and dust In order to improve the welding working environment and prevent atmospheric pollution, it is necessary to collect the smoke and dust generated during the welding process to prevent it from spreading in the workshop, and then use high-efficiency purification equipment to remove it.
Collection of welding fume. There are two ways to collect welding smoke and dust. Local exhaust. Set up a smoke exhaust hood on the side or top of the fixed welding operation point. Use the power of the fan to extract the smoke and dust on the spot to achieve the purpose of improving the indoor environment. This method saves air volume. The effect is good and energy is saved. The commonly used purification equipment is the mobile welding smoke purifier for comprehensive ventilation. In most cases, the workstation is moved and the workpiece does not move, and the smoke generation points are constantly changing, so the smoke cannot be collected with a local exhaust hood. At this time, in order to maintain a certain degree of cleanliness in the workshop, it is necessary to adopt a comprehensive air exchange method. The number of air exchanges in the workshop shall be carried out in accordance with relevant regulations. Generally, at a certain height of the workshop, which is considered to be the area with the densest smoke, a comprehensive ventilation hood is installed, and some use a method of blowing and sucking at the same time, so that an air curtain is formed at a certain height in the upper part of the workshop to absorb the rising smoke. Lock it and push it to the exhaust hood to eliminate smoke. Compared with the local exhaust method, the comprehensive ventilation method has large air volume, poor smoke exhaust effect, and high energy consumption. Especially in winter heating areas, a large amount of energy needs to be consumed to supplement the heat loss of the exhaust air. For example, if a machinery manufacturing factory calculates based on the consumption of welding rods, the exhaust air volume reaches ten sixth cubic meters per hour, and it needs to supplement ten fifth cubic calories of heat per hour. If purification equipment is used to process these exhaust gases, It is conceivable that the equipment is huge, so comprehensive ventilation should be reasonably adopted after analysis according to the specific situation. The commonly used equipment is the central welding fume purifier.
Development of welding flue gas purification equipment. The particle size of welding fume is very fine. According to Japanese data, the particle size of manual arc welding fume is usually between 1 and 2. The particle size of low-hydrogen welding rods occupies about 10%. According to the United States, the average particle size of carbon dioxide gas shielded welding fume is 1.5%, according to French data.
Shao, the particle size of welding fume is, therefore, the effect of using general dust removal method to deal with welding fume is very poor. In the past, due to technical, economic and other reasons in our country, the collected welding fumes were generally discharged directly into the atmosphere without purification, which had a certain impact on the surrounding environment. In recent years, due to my country's emphasis on environmental protection and labor protection, it has strengthened foreign technical exchanges and technology introduction. By digesting and absorbing foreign advanced technology, it has promoted the development and development of my country's welding fume control technology and achieved good results.
