[0027] The present invention is further described in detail below in conjunction with the embodiments:

[0028] A waste gas treatment device for a petrochemical central laboratory comprises a tower body 1, an air inlet 2 is provided at one side of the bottom of the tower body 1, a water circulation mechanism 3 is provided at the bottom end of the tower body 1, and a discharge mechanism 4 is provided at the top end of the tower body 1.

[0029] The water circulation mechanism 3 includes a circulating water tank 31, which is fixedly installed at the bottom of the tower body 1. A deodorant tank 32 is fixedly installed on the top of one side of the circulating water tank 31. A wastewater discharge port 33 is opened on one side of the circulating water tank 31. A water pump 34 is fixedly connected to the other side of the circulating water tank 31. A water pipe 35 is fixedly connected to the output end of the water pump 34. A water spray head 36 is welded to the output end of the water pipe 35. The deodorant tank 32 is connected to the circulating water tank 31 through a water pipe. The water pipe 35 extends to the inside of the tower body 1. The deodorant tank 32 can remove the peculiar smell in the water in the circulating water tank 31. The water pipe 35 provides a water source for the water spray head 36.

[0030] A packing layer 37 is provided at the middle end of the tower body 1 , a plug-in groove 38 is provided on one side surface of the packing layer 37 , a packing box 39 is movably installed inside the packing layer 37 , and a sealing strip 310 is welded to the inner surface of the packing box 39 . The sealing strip 310 is matched with the plug-in slot 38, and the packing layer 37 is arranged at the bottom of the water spray head 36. The sealing strip 310 cooperates with the plug-in slot 38 to install the packing box 39 into the packing layer 37, and the water spray head 36 sprays water to the packing layer 37. A water filter net 311 is arranged at the bottom of the packing box 39, and a handle is welded on the white surface of the packing box 39. The water filter net 311 allows the water sprayed from the packing box 39 to flow downward. By setting a circulating water tank 31 in conjunction with the water pump 34 and the water pipe 35, the water spray head 36 sprays water to the packing layer 37, and then in conjunction with the water filter net 311 and the deodorant box 32, the sprayed water flows back into the circulating water tank 31 and is deodorized, thereby reducing the working cost of the device and being beneficial to saving water resources. By setting the plug-in slot 38 in conjunction with the packing box 39 and the sealing strip 310, the packing box 39 can be separated from the packing layer 37, and the packing in the box body can be replaced, thereby ensuring that the device can continuously purify the exhaust gas.

[0031] The discharge mechanism 4 includes a demisting layer 41, which is fixedly installed on the top of the tower body 1. A filter screen 42 is arranged at the bottom of the demisting layer 41, and the demisting layer 41 can remove the mist generated in the tower. Activated carbon 43 is placed at the bottom of the filter screen 42. An exhaust port 44 is opened at the top of the demisting layer 41. The filter screen 42 cooperates with the activated carbon 43 to adsorb impurities in the exhaust gas, and the exhaust port 44 discharges the purified exhaust gas. By arranging the demisting layer 41 in cooperation with the filter screen 42 and the activated carbon 43, impurities in the exhaust gas that are difficult to decompose are adsorbed, thereby further improving the purification effect of the device.

[0032] The following is a detailed description of the working principle of the waste gas treatment device in the petrochemical center laboratory.

[0033] In actual operation, Figure 1-5 As shown, when the device is used, the exhaust gas is first input into the tower body 1 through the air inlet 2, and then the water in the circulating water tank 31 is extracted by the water pump 34, and the water is sprayed on the filler inside the stuffing box 39 through the water pipe 35 and the water spray head 36 to purify the exhaust gas. Then, the exhaust gas passes through the demisting layer 41 and the filter screen 42 upward, and the activated carbon 43 on the surface of the filter screen 42 adsorbs the impurities in the gas, and further purifies the exhaust gas, thereby improving the purification effect of the device. The purified gas is then discharged from the tower body 1 through the exhaust port 44. Finally, the sprayed water passes through the water filter screen 311 at the bottom of the stuffing box 39 and flows back into the circulating water tank 31, and then the water in the box is deodorized through the deodorant box 32, thereby ensuring that the water in the circulating water tank 31 can be recycled, reducing working costs and saving resources.

[0034] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
