[0047] The working principle of the utility model is as follows:

[0048] The tail gas enters the cloth bag dust removal device 4 through the tail gas pipeline 1, and after cloth bag dust removal, enters the spray tank 6 upward through the pipeline, when the cloth bag dust removal device 4 runs for a period of time, the dust on the dust cloth bag 24 increases and needs to be cleaned in time to ensure the dust removal efficiency, the operator can control the bypass air pipe 13 to be opened, so that the tail gas is divided into a section and then flows into the cloth bag dust removal device 4 through the bypass air pipe 13, in the process, the tail gas drives the wind wheel 15 to rotate in the wind cavity 14, so that the transmission wheel a16 drives the transmission wheel b17 to rotate to provide power for the vibration mechanism 3;

[0050] After the exhaust gas enters the spray tank 6, it first goes down to the mixing chamber 28 of the spray tank 6. Since the spray agent sprayed from the spray mechanism above accumulates in the spray chamber 29, and the pipeline entering the spray chamber 29 is below the liquid level, the exhaust gas containing harmful gas first enters the liquid for the first step of treatment, and then is mixed and discharged upward through the hole of the mixing plate 27 into the spray chamber 29. In the process, the liquid sprayed by the spray chamber 29 is mixed downward with the upward gas for the second step of treatment. Finally, the exhaust gas is treated in the spray chamber 29. The cylinder 31 is rotated on the mounting seat 33 driven by the driving motor 30 to spray the agent, and the spray pipe 34 in the cylinder 31 is added with the agent sprayed by the nozzle 32 to remove the harmful gas in the exhaust gas for the third step of treatment.

In the process, the treatment water generated is controlled and adjusted by the liquid level meter 5 and the blowdown pipe 7 to ensure that the water level is located between the mixing plate 27 and the outlet of the pipeline of the spray tank 6. In this way, the harmful gas in the exhaust gas is removed through the three-step treatment steps to ensure the safety of the exhaust gas in the waste heat recycling equipment and reduce the risk of safety accidents caused by exhaust gas leakage.

[0051] The exhaust gas after dust removal and removal of harmful substances is discharged through the exhaust pipe 8, the outlet flow is monitored by the flow meter a9, and the flow is distributed to different heat-using equipment through the flow dividing air valve 12. Here, it can be respectively introduced into the solid waste drying device and the preheater to recycle the waste heat, or one of the pipelines can be connected to the heat exchanger to heat the agent at the front end of the spray pipe 34 to reduce the temperature difference between the spray agent and the exhaust gas and reduce the heat loss of the agent in the spray treatment process. The flow meters b10 and c11 are used to monitor the air pipe flow in the pipeline after the flow dividing air valve 12 divides the flow. After the flow data is fed back to the workshop control cabinet, the control cabinet controls the electric actuator 36 on the flow dividing air valve 12 to control the rotation of the valve body 37, which changes the inlet cross-sectional area of the pipelines at both ends to automatically control the air flow introduced into different heat-using equipment, thereby increasing the use range of the device.
