the generated condensed sewage enters a water collector, but a part of mixed tail gas exists and is connected to a radiator; and a part of the mixed tail gas is also sent to the radiator; when the radiator is treated, cold air flows through the radiator for treatment under the action of the fan and exchanges heat with mixed tail gas flowing through the radiator, so that the mixed tail gas is further cooled, and water vapor in the mixed tail gas is completely condensed; the radiator discharges gas, the discharged residual tail gas is only organic waste gas, and the organic waste gas enters the exhaust pipe and finally enters the subsequent organic waste gas burning furnace through the exhaust port discharging equipment. The condensed water generated at the heat recoverer can be connected into the radiator through the water collector and utilized, and is cooled by cold air together with the mixed tail gas entering the radiator, and then is converged with the condensed water generated at the radiator and flows into the condensed water tank.
Through the treatment, the water vapor in the mixed tail gas is fully cooled and condensed at the heat recoverer and the radiator, so that only a small amount of organic waste gas is left through the exhaust port to be discharged out of the equipment, and the operation load and the failure rate of the subsequent organic waste gas burning furnace can be reduced; meanwhile, the waste heat contained in the mixed tail gas is recycled in the heat recoverer and used for heating the heating circulating water, and the heating circulating water is used for other heating, equipment heating and the like, so that the economic value generated by heat energy waste is reduced, and the heat pollution to the environment is reduced. All condensed sewage is collected, temperature-judged and cooled by the air cooling radiating component to reach a lower temperature, so that the condensed sewage can be discharged through the sewage pipe group, and the requirement on subsequent sewage treatment equipment is reduced. Furthermore, when the organic matter-water vapor mixed tail gas entering the equipment fluctuates, the intelligent control cabinet can perform intelligent judgment based on each temperature and pressure measuring point so as to control the variable frequency operation of the fan and the circulating water pump, so that the dual functions of heat recovery and water vapor condensation are ensured, the water vapor in the mixed tail gas can still be completely cooled, and the heat recovery efficiency is ensured; the whole heat recovery efficiency of the equipment is high, and the effect of removing and treating the organic matter-water vapor mixed tail gas is good.
