DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0020] A harmful gas treatment device for environmental protection engineering, such as Figure 1-Figure 3 As shown, it includes a box body 1, an air intake pipe 2, an activated carbon filter plate 3, a partition 9, a spray assembly, an exhaust pipe 10, a gas sensor 11, a second electric valve 12, an air delivery pipe 13, an air pump 14, a controller 17 and a liquid inlet pipe 19. The upper side of the box body 1 is provided with an air intake pipe 2, and the inside of the box body 1 is provided with an activated carbon filter plate 3, a partition 9 and a spray assembly. The partition 9 is L-shaped, and the activated carbon filter plate 3 is located on the upper side of the partition 9 and the spray assembly. The lower side of the box body 1 is filled with a neutralizing liquid, and the level of the neutralizing liquid is not high. An exhaust pipe 10 is provided on the right side of the box body 1 at the lower side of the partition 9. The exhaust pipe 10 is located on the lower side of the right end of the partition 9. A gas sensor 11 and a second electric valve 12 are provided on the exhaust pipe 10. The second electric valve 12 is connected to the upper side of the box body 1 through an air supply pipe 13. An air pump 14 is provided on the air supply pipe 13. A controller 17 is provided on the front side of the box body 1. The spray assembly, the gas sensor 11, the second electric valve 12 and the air pump 14 are all electrically connected to the controller 17. A liquid inlet pipe 19 is provided on the lower side of the box body 1.

[0021] During use, harmful gases enter the box body 1 from the air inlet pipe 2, come into contact with the harmful gases through the activated carbon filter plate 3, and can be filtered. At the same time, the spray component sprays neutralizing liquid on the filtered harmful gases. The neutralizing liquid fully reacts with the harmful substances inside the harmful gases to treat the harmful gases. The treated gas passes through the exhaust pipe 10, and the gas sensor 11 detects the treated gas. When the treated gas does not meet the standards, the air pump 14 re-transports the gas to the upper side of the box body 1 for re-processing, and then discharges it after meeting the standards.

[0022] like Figure 2 and Figure 4As shown, the spray assembly includes a first electric valve 4, a liquid infusion pipe 5, a water pump 6, a spray rack 7 and a spray head 8. A liquid outlet pipe is provided at the left lower side of the box body 1, and the first electric valve 4 is provided on the liquid outlet pipe. A liquid infusion pipe 5 is connected between the first electric valve 4 and the middle of the inner side of the box body 1, and the liquid infusion pipe 5 is provided with a water pump 6. A spray rack 7 is provided inside the box body 1. The liquid infusion pipe 5 extends into the interior of the box body 1 and is connected to the spray rack 7. A plurality of spray heads 8 are provided on the spray rack 7. The heads 8 are evenly distributed on the spray rack 7 from top to bottom. When spraying the neutralizing liquid, the water pump 6 transports the neutralizing liquid stored at the bottom of the box 1 to the spray rack 7 through the infusion pipe 5, and sprays it out through the spray head 8. After the neutralizing liquid is fully in contact with the harmful gas, the neutralizing liquid falls back to the bottom of the box 1 and is extracted by the water pump 6 again, starting a new round of spraying cycle. When the neutralizing liquid needs to be replaced, the neutralizing liquid is discharged through the first electric valve 4 and sent in through the liquid inlet pipe 19.

[0023] like Figure 2 As shown, a first fan 15 and a second fan 16 are also included. The first fan 15 is provided at the connection between the box body 1 and the exhaust pipe 10, and the wind direction of the first fan 15 is to the right. A second fan 16 is provided on the upper side of the interior of the box body 1, and the wind direction of the second fan 16 is downward. The second fan 16 is located at the upper left of the partition 9. The first fan 15 is provided at the connection between the box body 1 and the exhaust pipe 10, which helps to discharge the treated gas smoothly. The second fan 16 is provided on the upper side of the interior of the box body 1 to accelerate the circulation and flow of the gas in the box body 1.

[0024] like Figure 1 As shown, a transparent portion 18 is also included. The transparent portion 18 is provided at the lower front portion of the box body 1. Through the transparent portion 18, the operator can directly see the clarity of the neutralizing liquid in the box body 1, whether there are impurities or sediments, etc., so as to judge whether the neutralizing liquid needs to be replaced. At the same time, the operator can see the capacity of the neutralizing liquid in the box body 1 and replenish it in time when the capacity is insufficient.

[0025] like Figure 2 As shown, a filter screen 21 is also included. The filter screen 21 is arranged inside the air inlet pipe 2. The filter screen 21 can filter out large particle impurities in the gas entering the box body 1, protect the subsequent activated carbon filter plate 3 and the spray component, and extend their service life.

[0026] The lower side of the box body 1 is inclined toward the first electric valve 4 . The inclined state of the lower side of the box body 1 allows the neutralizing liquid to flow toward the first electric valve 4 , which is convenient for replacing the neutralizing liquid and extracting it by the water pump 6 .

[0027] The above description is only an example of the implementation of the present invention and is not intended to limit the present invention. Any equivalent replacement made within the principle of the present invention shall be included in the protection scope of the present invention. The contents not elaborated in the present invention belong to the existing technology known to the technicians in this professional field.
