[0015] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of an exhaust gas treatment device of the utility model in conjunction with the accompanying drawings.

[0016] like Figure 1-3As shown, the utility model is a waste gas treatment device, comprising a waste gas dissolving tank 1; an air inlet 101 is arranged on one side of the waste gas dissolving tank 1; an adsorption chamber 2 is arranged on the top of the waste gas dissolving tank 1 through a pipeline; a fan 3 is arranged on one side of the adsorption chamber 2 through a pipeline; a vertical connecting pipe 4 is vertically arranged in the waste gas dissolving tank 1; a circulating pump group 5 is arranged on one side of the waste gas dissolving tank 1; the liquid inlet of the circulating pump group 5 is connected to the bottom of the waste gas dissolving tank 1 through a pipeline; a liquid delivery pipe 6 is arranged at the liquid outlet of the circulating pump group 5, extending to the upper part of the waste gas dissolving tank 1 and connected with the vertical connecting pipe 4; a plurality of annular spray assemblies 7 are arranged on the outside of the vertical connecting pipe 4, and the annular spray assemblies 7 are composed of a plurality of nozzles 12 connected to the vertical connecting pipe 4; a plurality of first arc-shaped baffles 8 are arranged on the outside of the vertical connecting pipe 4; a plurality of second arc-shaped baffles 9 are arranged between two adjacent first arc-shaped baffles 8 on the inner wall of the waste gas dissolving tank 1.

[0017] Combination Figure 1-3 As shown, when in use, a certain amount of dissolving liquid is set at the bottom of the waste gas dissolving tank 1, and industrial waste gas is introduced into the waste gas dissolving tank 1 through the air inlet 101. At the same time, the circulating pump group 5 is started, and the circulating pump group 5 sucks the dissolving liquid in the waste gas dissolving tank 1 and transports it to the vertical connecting pipe 4 through the liquid delivery pipe 6, and sprays it through multiple annular liquid spraying components 7 to form multiple dissolving liquid water mist barriers, and performs multiple dissolving and adsorbing operations on the waste gas passing through the waste gas dissolving tank 1. The first arc baffle 8 cooperates with the second arc baffle 9 to block the waste gas passing through the waste gas dissolving tank 1. During the rising process of the exhaust gas in the gas dissolving tank 1, a circumventing rising mode is formed on the inner and outer sides, which increases the travel of the exhaust gas in the exhaust gas dissolving tank 1. The water curtain of the dissolved liquid sprayed by the annular spray assembly 7 composed of multiple nozzles 12 is helpful for the harmful substances in the exhaust gas to contact and react with the dissolved liquid more fully, thereby improving the removal effect of the harmful substances in the exhaust gas. The negative pressure suction force generated by the fan 3 on the adsorption bin 2 and the exhaust gas dissolving tank 1 accelerates the speed of the exhaust gas passage, increases the exhaust gas harm removal effect but does not affect the overall efficiency of exhaust gas treatment.

[0018] The waste gas after passing through the waste gas dissolution tank 1 arrives through a pipeline, and a chamber door 10 is arranged on one side of the adsorption chamber 2; a plurality of filter screens 11 are arranged in the adsorption chamber 2, and harmful particles in the waste gas that cannot be dissolved or reacted with the dissolving liquid are adsorbed by the plurality of filter screens 11, which can further remove particulate matter and fine harmful substances in the waste gas, and the setting of multiple layers of filter screens can ensure that the waste gas is filtered multiple times, and each layer of filter screen can be set to a targeted size to filter specific types of harmful particles, thereby increasing the overall waste gas removal effect, improving the purification efficiency and purification effect, and the filter screen that has been used for a long time can be replaced through the position of the chamber door 10, which is relatively convenient to operate and does not delay the waste gas treatment work.

[0019] The first arc baffle 8 and the second arc baffle 9 are bent upward. The first arc baffle 8 and the second arc baffle 9 that are curved upward will increase the exhaust gas stroke without affecting the exhaust gas travel speed, thereby facilitating the exhaust gas to move upward in the exhaust gas dissolution tank 1.

[0020] The first arc baffle 8 and the second arc baffle 9 are both provided with a plurality of through holes 13. A portion of the exhaust gas that reaches the first arc baffle 8 or the second arc baffle 9 can rise through the through holes 13, which can effectively disperse the exhaust gas, increase the contact area between the dissolved liquid sprayed by the annular liquid spraying assembly 7 and the exhaust gas, and increase the impurity removal effect of the dissolved liquid on the exhaust gas. At the same time, the dissolved liquid on the first arc baffle 8 and the second arc baffle 9 can fall through the through holes 13, gather at the bottom of the exhaust gas dissolution tank 1, and be recycled through the circulation pump group 5 after treatment.

[0021] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
