In the era when the welding smoke treatment equipment has not yet solved the problem of food and clothing, people even envy the kitchen masters who have the condition of smelling the vegetable fragrance every time they contact the oily. Oil fume purification equipment is naturally unnecessary.
The welding smoke processing equipment industry is in the primary stage of rapid development and maturity. From the perspective of environmental protection technology, if the cost is not counted, the current technology can completely control the oil fume exhaust gas to the indoor air emission standard, but the "no cost" statement is in violation of environmental protection principles. Affordable and affordable catering companies are the basic criteria for judging the practicality of the technology for fume purification equipment. Fume purification technology without a more efficient cost-effective ratio is not market viable.
The negative pressure ventilation and cooling project includes the meaning of ventilation and cooling, and the problems of ventilation and cooling are solved at the same time. Negative pressure fan is also used in the fields of positive pressure water curtain environmental air-conditioning, positive pressure air supply, and positive pressure blower. Negative pressure fan has the characteristics of large volume, large air duct, large wind blade diameter, large air exhaust volume, ultra low energy consumption, low speed, low noise and so on. Negative pressure fans are mainly divided into galvanized sheet square negative pressure fans and FRP horn negative pressure fans from the structural material.
