Mounting seats are installed above and below one side inner wall of the evaporator body. A steam delivery pipe A is installed above one side outer wall of the evaporator body. One end of the steam delivery pipe A is installed with a steam tank. Since there are gases generated during wastewater evaporation inside this kind of evaporator for treating high-salt and high-ammonia-nitrogen wastewater, when the evaporator is opened for maintenance, the gases evaporated from the wastewater remaining inside the evaporator are likely to diffuse into the treatment workshop, affecting the workshop environment.

The blower assembly includes a connecting pipe. A flange plate is integrally arranged in the middle of the connecting pipe. One end of the connecting pipe is flange-connected to an inner air delivery pipe. The other end of the connecting pipe is flange-connected to a valve. An outer air delivery pipe is installed between the valve and the air outlet of the blower.
[0006] Preferably, heat medium connecting pipes are integrally arranged on both the upper and lower sides of one side of the jacket.

[0017] The present utility model will be specifically described below with reference to the accompanying drawings. As shown in the attached Figure 1 and the attached Figure 2 figures, an evaporator for treating high-salt and high-ammonia-nitrogen wastewater includes an evaporator tank 1. A jacket 2 is integrally provided on the outside of the evaporator tank 1. Heat medium connecting pipes 3 are integrally provided on both the upper and lower sides of one side of the jacket 2. A discharge valve 4 is flange-connected to the lower discharge port of the evaporator tank 1. A feed valve 5 is flange-connected to the upper feed port of the evaporator tank 1. A three-way exhaust pipe 6 is flange-connected to the opening for discharging steam provided on the upper part of the evaporator tank 1. The three-way exhaust pipe 6 is connected to a blower assembly 7.
[0018] In this embodiment, as shown in the attached Figure 3 figures, the blower assembly 7 includes a connecting pipe 71. A flange plate is integrally provided in the middle of the connecting pipe 71. One end of the connecting pipe 71 is flange-connected to an inner air supply pipe 72. The other end of the connecting pipe 71 is flange-connected to a valve 73. An outer air supply pipe 74 is installed between the valve 73 and the air outlet of the blower 75.
[0019] In this embodiment, specifically, the inner air supply pipe 72 is arranged inside the evaporator tank 1.
[0020] In this embodiment, specifically, the flange of the connecting pipe 71 is fixedly installed in a sealed manner at one end of the three-way exhaust pipe 6.
[0021] In this embodiment, specifically, the air outlet of the inner air supply pipe 72 is opened at the lower end of the inner air supply pipe 72.
[0022] Working principle
[0023] In the present utility model, during use, the heat medium connecting pipe 3 is connected to a heat exchanger or other heating equipment that generates heat medium externally. The heat medium enters the jacket 2 and heats the high-salt and high-ammonia-nitrogen wastewater in the evaporator tank body 1 through the evaporator tank body 1, enabling the high-salt and high-ammonia-nitrogen wastewater to be evaporated. The feed valve 5 is used to put the high-salt and high-ammonia-nitrogen wastewater into the evaporator tank body 1, and the discharge valve 4 is used to discharge the evaporated high-salt and high-ammonia-nitrogen wastewater. The upper end of the three-way exhaust pipe 6 is used to discharge the evaporation gas. When it is necessary to open the evaporator tank body 1 for maintenance, since there is evaporation gas of wastewater in the evaporator tank body 1, the fan 75 is connected to an external power source. The fan 75 blows air into the evaporator tank body 1 through the external air supply pipe 74, the valve 73, the connecting pipe 71, and the inner air supply pipe 72. The blown air is mixed with the wastewater evaporation gas and discharged from the three-way exhaust pipe 6, thereby reducing the concentration of the wastewater evaporation gas in the evaporator tank body 1 and reducing the overflow of the wastewater evaporation gas after opening the evaporator tank body 1.
