Exhaust gas absorption tower energy recovery and environmental protection equipment are widely used in electric power, chemical industry, electrical and electronic, metallurgy, brewing and other fields of equipment. The exhaust gas dry absorption tower that has been used in the past can only neutralize and purify, and has not changed recycling for a long time. A good method makes a lot of energy wasted. Therefore, our company has successfully developed a method for absorbing and recycling exhaust gas.
