What is the treatment method for industrial waste gas recovery? 

Industrial waste gas usually carries a lot of heat, direct emission wastes a lot of energy, and it is not energy-saving and environmentally friendly, so how to deal with industrial waste gas?

1. Exhaust gas recovery  (heating air)

   

2. Industrial waste gas heat recovery (heating water, cooling waste gas)

   

Through the principle of heat exchange, the heat carried by the high-temperature gas is partially recovered to reduce the gas temperature, and at the same time, part of the recovered waste heat is used for industrial production purposes and domestic purposes.

Hot air can be used for: workshop heating / preheat drying

Hot water can be used for: boiler make-up water / bath water / dye vat hot water
