[0017] Refer to Figures 1-4, Wastewater explosion elimination treatment device, including sedimentation tank 1 and evaporation tank 2. There is a mounting frame 3 fixed at the top pool opening of sedimentation tank 1. On the surface of mounting frame 3, there are a stirring mechanism 4, a first liquid level gauge 5 and a pH tester 6. There is a second liquid level gauge 7 at the top pool opening of evaporation tank 2. The pH tester 6 determines whether to supplement NaOH solution according to the pH value of the solution in the tank. The first liquid level gauge 5 is used to detect the waste liquid volume in sedimentation tank 1, and the second liquid level gauge 7 is used to detect the solution volume in evaporation tank 2. Inside evaporation tank 2, there is also configured an electric heating system and a hot water circulation heating system, which is a conventional evaporation system and will not be explained in detail here;

[0018] The stirring mechanism 4 includes a support plate 41 installed on the surface of mounting frame 3. On the upper surface of support plate 41, there is a motor support 42 fixed. On the upper surface of motor support 42, there is a driving motor 43 fixed. The output end of driving motor 43 penetrates through motor support 42 and extends below motor support 42. On the surface of support plate 41 and directly below driving motor 43, there is a stirring rod 44 movably installed through. At the bottom of stirring rod 44, there is a stirring blade 45 fixed. Between the top of stirring rod 44 and the output end of driving motor 43, there is a fixation. On the surface of support plate 41 and parallel to stirring rod 44, there is an air duct 46 fixed. Between the compressed gas interface at the top of air duct 46 and the output end of the air compressor, there is an air duct 46 fixed. When stirring the waste liquid, compressed gas is introduced to improve the mixing efficiency.

[0019] On both sides of the filter press 8, there are respectively placed a feeding pump 9 and a discharging pump 10. Between the input end of feeding pump 9 and the bottom side wall of sedimentation tank 1, there is a first feeding pipe connected and fixed. Between the output end of feeding pump 9 and the feeding interface of filter press 8, there is a second feeding pipe connected and fixed. Between the input end of discharging pump 10 and the discharging interface of filter press 8, there is a first discharging pipe connected and fixed. At the output end of discharging pump 10, there is a second discharging pipe fixed. The end of the second discharging pipe is introduced from the top of evaporation tank 2.

[0020] Below the filter press 8, there is a waste collection box placed, which is used to collect the waste after filter pressing treatment.

[0021] At the top pool opening of mounting frame 3, there is a first mounting plate fixed for fixing and installing the first liquid level gauge 5. On the surface of the first mounting plate, there is a fixing frame fixed for sleeving and fixing the pH tester 6. The bottom detection end of the pH tester 6 extends into sedimentation tank 1.

[0022] At the top pool opening of evaporation tank 2, there is a second mounting plate fixed for fixing and installing the second liquid level gauge 7.

[0023] The air duct 46 penetrates through the support plate 41, and one end of the air duct 46 extending above the support plate 41 is fixed with a compressed gas interface. Compressed air is compressed by an air compressor, and the air outlet end of the air compressor is connected and fixed to the compressed gas interface at the top of the air duct 46 through a pipeline. During the stirring operation, compressed gas is introduced into the sedimentation tank 1 to accelerate the solution reaction efficiency.

[0024] When the device is in use, the waste liquid after detonation is discharged into the sedimentation tank 1 through a pipeline. The pH tester 6 determines whether to supplement the NaOH solution according to the pH value of the solution in the tank. After the NaOH solution is supplemented, the drive motor 43 of the stirring mechanism 4 operates to drive the stirring rod 44 and the stirring blades 45 to rotate, performing the mixing operation of the NaOH solution and the waste liquid, and compressed air is switched on to improve the stirring and mixing effect of the solution in the sedimentation tank 1 by using the compressed air. After stirring and mixing for a set time, the first liquid level gauge 5 is used to monitor the liquid level in the sedimentation tank 1. If the set depth value is reached, the waste liquid in the sedimentation tank 1 is automatically pumped out and fed into the filter press 8. The filter press 8 is used to filter the waste liquid in the sedimentation tank, and the filtered clear water is sent to the evaporation tank 2;

[0025] The amount of clear water in the evaporation tank 2 is detected by the second liquid level gauge 7. If the set depth value is reached, the electric heating system and the hot water circulation heating system are automatically started to evaporate the waste water. If it is detected that the liquid level in the evaporation tank 2 reaches the set lower limit, the evaporation is automatically stopped. Thus, the detonation treatment of the waste water is completed;

[0026] The parameters of the sedimentation tank 1 and the evaporation tank 2 are transmitted to the master control room in real time, and the action states of the actuators such as the valve cylinders are also displayed on the operation interface of the master control room, and manual intervention and adjustment can be performed.
