The main polluting components of the acid-base waste gas are nitric acid mist, hydrogen chloride, sulfuric acid mist, cyanide, chromic acid mist, alkali mist, etc. In order to protect the environment and human health, it is necessary to treat the acid-base gas. The principles of acid-base gas treatment include: eliminating the pollution source, reducing pollution emissions, treating the waste gas, etc. Among them, the waste gas treatment needs to use a purification tower.

[0021] Embodiment: An exhaust gas purification tower for chemical production, please refer to Figures 1 to 5 , which includes a tower body 1, a ladder 4, an arc-shaped observation window 5, a spray pipe 6, a pipeline 61, a first ball valve 7, a second ball valve 71, a water pump 8, a water tank 9, a filter screen 10, a grid plate 11, a connecting block 111, a pin 112, a connecting plate 12, a motor 13, a small pulley 14, a flat belt 15, and a large pulley 16. There are three tower bodies 1, and the three tower bodies 1 are designed in a stacked manner from top to bottom, and the interiors of the three tower bodies 1 are all hollow. An air inlet hole 2 is opened on the right side of the lowermost tower body 1, and an air outlet 3 is opened at the top of the uppermost tower body 1. Flanges are provided at both the air inlet hole 2 and the air outlet 3, making the connection between the external pipeline 61 and the air inlet hole 2 and the air outlet 3 tighter. A ladder 4 is vertically installed between the outer sides of the three tower bodies 1, and arc-shaped observation windows 5 are installed on the sides of the upper two tower bodies 1 for observing the purification process. Spray pipes 6 are horizontally installed inside the upper two tower bodies 1, and the water outlet ports of the spray pipes 6 are distributed in a circumferential manner, making the spraying of the spray pipes 6 more uniform. The left ends of the two spray pipes 6 penetrate through the left side of the tower body 1, and a pipeline 61 is connected between the left ends of the two spray pipes 6. The pipeline 61 is fixed on the outer side of the three tower bodies 1, and a first ball valve 7 is installed in the middle of the pipeline 61. The rear side of the lowermost tower body 1 is communicated with a water tank 9. The water tank 9 is designed with a transparent material. A filter screen 10 is connected to the middle part of the interior of the water tank 9. There are two water outlet ports on the left side of the water tank 9, and a second ball valve 71 is provided at the water outlet port, and a water pump 8 is installed at the other water outlet port. The water outlet of the water pump 8 is communicated with the pipeline 61. Grid plates 11 are placed at the lower inner parts of the upper two tower bodies 1, and each grid plate 11 is located below the adjacent spray pipe 6. Plug pins 112 are connected between the outer sides of each grid plate 11 and the outer side of the adjacent tower body 1. A connecting plate 12 is connected to the right side of the uppermost tower body 1, a motor 13 is installed on the right side of the connecting plate 12, the output shaft of the motor 13 is connected with a small pulley 14, a large pulley 16 is rotatably connected to the left inner part of the connecting plate 12, a flat belt 15 is wound between the large pulley 16 and the small pulley 14, a rotating rod is connected to the bottom of the large pulley 16, connecting blocks 111 are connected to both the upper and lower ends of the rotating rod, and the connecting blocks 111 are all connected to the adjacent grid plates 11.

[0022] When the exhaust gas purification tower is needed, first connect the matching external pipe 61 at the position of the air inlet 2 and the air outlet 3, then add an appropriate amount of sodium hydroxide absorption liquid and filler to the water tank 9 and the grid plate 11, and add the sodium hydroxide absorption liquid through the water injection port on the water tank 9. After the injection is completed. Pull out the latch 112 so that the grille plate 11 is not fixed, and drive the small pulley 14 to rotate by starting the motor 13, thereby driving the large pulley 16 to rotate, and then driving the flat belt 15, the rotating rod and the connecting block 111 to rotate, and finally driving the grille plate 11 to rotate outward, so that the grille plate 11 is opened, and then the staff can climb to the position of the grille plate 11 through the escalator 4 and fill the grille plate 11 with a proper amount of filler. After filling, the staff comes down from the escalator 4 and controls the motor 13 to reverse, drive the small pulley 14 to reverse, drive the large pulley 16 and the flat belt 15 to transmit in the opposite direction, thereby driving the rotating rod, the connecting block 111 and the grille plate 11 to reset, and insert the latch 112 back to the original position to fix the grille plate 11. Then the staff began to discharge the waste gas into the purification tower, and started the water pump 8 and the first ball valve 7 at the same time. The water pump 8 will suck the sodium hydroxide absorption liquid in the water tank 9, and then transport it to the spray pipe 6 through the pipeline 61. The sodium hydroxide absorption liquid will be evenly sprinkled through the spray pipe 6. The waste gas will pass through two layers of packing layers, and the waste gas and the sodium hydroxide absorption liquid will fully contact and absorb and neutralize in gas-liquid two-phase. After purification, the waste gas is discharged through the air outlet 3. Through the setting of the arc-shaped inspection window 5, it is convenient to observe the purification process of the waste gas. The sodium hydroxide absorption liquid sprayed from the spray pipe 6 will eventually flow into the lowermost tower body 1. Since the water tank 9 is connected to the tower body 1, the sodium hydroxide absorption liquid in the tower body 1 will flow back into the water tank 9. In this way, the entire purification process of the waste gas can be realized. When purification is not needed, the discharge of waste gas into the tower body 1 can be stopped. When it is necessary to clean the waste filler, the filler inside the grid plate 11 can be easily cleaned by simply repeating the above operation of opening the grid plate 11, without the need to use professional equipment to assist in the cleaning.
