METHOD AND DEVICE FOR REDUCTION OF TOXICITY OF EXHAUST GASES OF POWER PLANT Russian patent published in 1995 - IPC

FIELD: power plants. SUBSTANCE: method consists in wet cleaning by means of neutralizing liquid in cyclone foam apparatus; used neutralizing liquid is discharged to settler and cleaned liquid is delivered to cyclone foam apparatus. To enhance efficiency of cleaning the exhaust gases and to reduce carrying away heat and moisture, exhaust gas heat is removed for recovery and cleaned exhaust gases are partially directed to power plant inlet; flow rate of recirculated gas and content of moisture in it are regulated. To realize this method, use is made of device provided with power plant with intake manifold and exhaust branch pipe, settler with pump at the outlet branch pipe, manifold for feeding the neutralizing liquid to contact apparatus, liquid flow rate regulators and temperature regulators and recirculating cleaned exhaust gas regulators and built-in heat exchanger. EFFECT: enhanced efficiency. 2 cl, 1 dwg
