2. The utility model discloses the heat exchanger that sets up in circulating pipe department, effectual unnecessary heat in the tail gas of having utilized.
3. The utility model discloses the grid that sets up in spraying the jar and establish the polypropylene clean shot on the grid, further improvement the device to the processing degree of industry tail gas.
Drawings
Fig. 1 is a schematic diagram of the present invention.
In the figure, 1 is a first liquid caustic soda tank, 2 is a diffusion umbrella, 3 is a heat exchanger, 4 is a first-stage spraying tank, 5 is a circulating pump, 6 is a second liquid caustic soda tank, 7 is a third-stage spraying tank, 8 is a conductivity meter, and 9 is a second-stage spraying tank.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, the utility model relates to an industrial tail gas processing apparatus, including the one-level of UNICOM in proper order spray jar 4, the second grade sprays jar 9 and tertiary jar 7 that sprays, the bottom that the one-level sprayed jar 4 is equipped with the intake pipe that lets in tail gas and the circulating pipe that is used for the heat transfer, and the circulating pipe is put through with the diffusion umbrella 2 that sets up at the one-level and spray tank deck portion, still is equipped with heat exchanger 3 on the circulating pipe.
The top of the first-stage spraying tank 4 is also provided with an air pipeline, and the other end of the air pipeline is connected to the bottom of the second-stage spraying tank; the top of the second-stage spraying tank is also provided with a diffusion umbrella which is communicated with a circulating pump 5 arranged in the first liquid caustic soda tank; the bottom of the second-stage spraying tank is also provided with a conductivity meter 8 for controlling the discharge of spraying water in the tank.
The top of the second-stage spraying tank is also provided with a gas pipeline, and the other end of the gas pipeline is connected to the bottom of the third-stage spraying tank; the top of the third-stage spraying tank is also provided with a diffusion umbrella which is communicated with a water pump arranged in the second liquid caustic soda tank; the bottom of the second-level spraying tank is also provided with a conductivity meter 8 for controlling the discharge of spraying water in the tank.
The top of the third-stage spraying tank is also provided with an opening for discharging tail gas. A centrifugal fan is arranged in the air pipeline. The bottom of the first-stage spraying tank is provided with a water pump which is communicated with a circulating pipe at the bottom of the first-stage spraying tank. Tail gas enters a first-stage spraying tank and is in reverse contact with spraying water uniformly diffused by a diffusion umbrella in the tank; the inside of each spraying tank is provided with three layers of grids, and the top layer of each grid is provided with a polypropylene hollow ball with the model number of 50.
The spray water in the first-level spray tank is conveyed to the heat exchanger through the water pump for the circulating pipe, the heat is exchanged for the material, and meanwhile, the heat exchanger is used for cooling treatment. After treatment, the spray water enters the primary spray tank again, and the tail gas enters the secondary spray tank from the top of the primary spray tank along an air pipeline.
Tail gas is conveyed to a secondary spraying tank through a centrifugal fan in an air pipeline and is in reverse contact with alkaline water uniformly diffused by a diffusion umbrella in the tank; the pH value of the alkaline water is 8-11 so as to neutralize the acidity in the tail gas and further reduce the temperature. And an online conductivity meter is arranged at the bottom of the secondary spraying tank, and when the conductivity of the spraying water exceeds 20us/cm, the liquid in the spraying tank is discharged.
Tail gas enters the three-stage spraying tank from the two-stage spraying tank, the acidity in the tail gas is neutralized again, the temperature is reduced for three times, gas meeting the environmental protection requirement is obtained, and the gas is discharged into the air through a gas discharge pipe of the three-stage spraying tank. Similarly, an online conductivity meter is arranged at the bottom of the spray tank, and the liquid in the spray tank is discharged when the conductivity of the spray water exceeds 20 us/cm.
