The invention discloses a reducing agent spraying and metering device, which comprises a reducing agent storing box, a supply pump, a metering valve, a mixing cavity, an atomizing nozzle, a controller, a switching valve and a low-pressure air pump, wherein a reducing agent of the reducing agent storing box is mixed in the mixing cavity through the supply pump and the metering valve, is then atomized through the atomizing nozzle, is sprayed into an exhaust pipe, is mixed with waste gas, and is reduced and purified; the low-pressure air pump is used for supplying pressure air to the mixing cavity during working of an engine, and sweeping the reducing agent in the supply pump and a pipeline behind the supply pump back into the reducing agent storing box when the engine stops working; and the switching valve is used for controlling and switching the reducing agent storing box to supply the reducing agent and pressure gas of the low-pressure air pump to sweep the supply pump and the pipeline behind the supply pump. An independent air source is adopted, so that the pressure is stable and does not fluctuate along with the change of the working condition of the engine, automobile compressed air is not consumed, and the potential safety hazard of compressed air leakage is eliminated. A cleaning method of the spraying and metering device is simple, and a complete effect is achieved.

The invention discloses a desulfurization wastewater zero discharge system for cascade utilization of flue gas waste heat and a working method thereof, belonging to the technical field of desulfurization wastewater treatment. Including the first air intake device, the second air intake device, the first air heat exchanger, the second air heat exchanger, the first flue gas heat exchanger, the second flue gas heat exchanger, spray drying tower, dust collector, Evaporation and concentration tower and desulfurization wastewater pool. Use the high-temperature flue gas at the tail of the boiler to increase the air temperature. Through the cascade utilization of the temperature, the high-temperature air evaporates and dries the desulfurization wastewater. The air after cooling is used for the concentration and reduction of the desulfurization wastewater. The dust collector is used to recover the dried salt in the wastewater. , The air heat exchanger is used to recover the heat in the outlet air of the system for air preheating. Compared with the traditional zero-discharge method of desulfurization wastewater, the waste heat in the flue gas is fully utilized, the concentration and drying of the wastewater are realized simultaneously, and the water balance and material balance of the gas in the original flue are less affected, so it has a good application prospect.
