The outer end of the condensing cylinder is provided with an angled tube, the outer end of the angled tube is provided with a liquid inlet pipe, a filter screen is fixed in the angled tube, the outer surface of the lower end of the angled tube is connected with a round cover by a thread, the heating cylinder is provided with a heater, the condensing cylinder is provided with a spiral condensing tube, the water suction pipe on the chemical pump is fixed to the inner surface of the lower end of the condensing cylinder, the end face of the water guide pipe on the chemical pump is fixedly connected to the heating cylinder, and the urine can be directly discharged through the reverse flow guide mechanism. The urea liquid is used to condense the gas after evaporation. There is no need to use circulating water and no waste of water resources. At the same time, a filter screen is set at the inlet and outlet to filter out internal residue particles. There are still some problems in the treatment of the exhaust gas treatment liquid by this device, that is, the exhaust gas treatment liquid flows directly into the heating cylinder.
