[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0023] To address the technical problem that existing exhaust gas treatment devices can only filter out dust from exhaust gases and are unable to treat harmful gases, this invention provides an exhaust gas treatment device that first absorbs dust from the exhaust gas and then absorbs harmful gases, ensuring that exhaust emissions meet national standards.

[0024] Please see Figures 1-4 , Figures 1-4 According to one embodiment of the present invention, a tail gas treatment device includes a purification mechanism 1. The purification mechanism 1 includes a purification cylinder 11, a sleeve 12, a dust collector 13, and an air guide 14. The sleeve 12 is connected to the purification cylinder 11, with one end of the sleeve 12 extending into the purification cylinder 11 and the other end located outside the purification cylinder 11 and provided with an air delivery end 12a. A cavity for holding purification liquid is formed between the sleeve 12 and the purification cylinder 11. The dust collector 13 is installed inside the sleeve 12 and is used to adsorb dust in the tail gas. The air guide 14 is connected to one end of the sleeve and is inserted into the cavity. The air guide 14 can guide the tail gas in the sleeve 12 into the cavity and contact it with the purification liquid.

[0025] Specifically, it also includes a gas collection mechanism 2, which includes a cover 21 and an air extraction component 22. The cover 21 has an installation space for installing the filter press, and the air extraction component 22 is connected between the installation space and the gas delivery end 12a. When the filter press is working, it will generate a large amount of exhaust gas. The cover 21 can prevent the exhaust gas from spreading into the production workshop. The air extraction component 22 extracts air from the cover 21 to send the exhaust gas inside the cover to the purification mechanism 1. Specifically, the cover 21 is also provided with multiple air inlets.

[0026] In actual use, the exhaust gas inside the cover 21 is drawn to the gas delivery end 12a by the exhaust gas extraction component 22. The exhaust gas enters the sleeve 12 through the gas delivery end. The dust collection component 13 can absorb the dust in the exhaust gas. Then, the exhaust gas in the sleeve 12 is transported to the cavity through the air guide component 14. The exhaust gas comes into contact with the purification liquid in the cavity. The purification liquid in the purification liquid can absorb the harmful gases in the exhaust gas.

[0027] It should be noted that, in one embodiment, the dust collection component 13 includes a partition 131 and a plurality of bag cylinders 132. The partition 131 is installed inside the sleeve 12 and divides the sleeve 12 into a dust collection chamber and an exhaust chamber. The plurality of bag cylinders 132 are disposed in the dust collection chamber and fixedly connected to the partition 131. The dust collection chamber is connected to the exhaust chamber via the plurality of bag cylinders 132.

[0028] It is understandable that dust in the exhaust gas can be adsorbed onto the filter bags, and the partition 131 has multiple perforations that correspond to the openings of each filter bag 132.

[0029] Based on the above scheme, in order to increase the contact area between the exhaust gas and the purification liquid, specifically, the air guide 14 includes a plurality of air pipes, which are spaced apart along the periphery of the sleeve 12. One end of the plurality of air pipes is connected to the exhaust chamber, and the other end is inserted into the cavity.

[0030] It should be noted that the other end of the multiple vent pipes extends to the bottom of the cavity, and the exhaust gas is transported into the cavity through the multiple vent pipes to come into contact with the purification liquid. The purification liquid in the cavity is a sodium hydroxide solution, which can treat the acidic harmful gases in the exhaust gas.

[0031] Based on the above solution, in order to further treat the alkaline harmful gases in the exhaust gas, the purification mechanism 1 specifically includes an installation pipe 15 and a venting component 16. The installation pipe 15 is connected to the purification cylinder 11, and a cavity for holding purification liquid is formed between the installation pipe 15 and the purification cylinder 11. The venting component 16 is connected to the top of the purification cylinder 11, and the air guide component 14 is inserted into the cavity. The venting component 16 can guide the exhaust gas in the cavity into the cavity and make it contact with the purification liquid.

[0032] It is understandable that the purification liquid contained in the cavity is a sulfuric acid solution. When alkaline harmful gases in the exhaust gas come into contact with the sulfuric acid solution, they can be absorbed by the sulfuric acid solution, thereby further improving the purification effect of the exhaust gas.

[0033] Based on the above scheme, in order to further increase the contact area between the exhaust gas and the purification liquid, specifically, the ventilation component 16 includes a plurality of ventilation pipes, which are arranged at intervals along the circumference of the purification cylinder 11, and the plurality of ventilation pipes are connected to the top of the cavity, with the other end inserted into the cavity; it should be noted that the other end of the plurality of ventilation pipes extends to the bottom of the cavity.

[0034] In addition, based on the above solution, in order to shake off the dust adsorbed on the bag cylinder and ensure that the air vents on the bag cylinder are not blocked, a back-blowing component 17 is specifically provided. The back-blowing component 17 can output high-pressure airflow to the opening of each bag cylinder to shake off the dust adsorbed on the bag cylinder.

[0035] It should be noted that the backflush component 17 is not limited to a specific structure. In one embodiment, the backflush component 17 includes an air tank 171, an air guide plate 172, and a plurality of jet pipes 173. The air tank 171 is fixed to the top of the purification cylinder 11. The air guide plate 172 is disposed in the exhaust chamber and connected to the air outlet of the air tank 171. The plurality of jet pipes 173 are connected to the air guide plate 172, and each jet pipe 173 is respectively inserted into each of the cloth bag cylinders 132.

[0036] Understandably, the gas storage tank 171 contains high-pressure gas, and the outlet of the gas storage tank 171 is equipped with a pulse valve. By opening the pulse valve, the high-pressure gas in the gas storage tank 171 can be ejected through multiple jet pipes 173.

[0037] Based on the above scheme, each of the jet pipes 173 is provided with a plurality of air holes at intervals along the axial direction, wherein the lower end of the jet pipe 173 extends to the bottom of the bag tube 132.

[0038] In one embodiment, the bottom of the cavity is connected to a first infusion tube, and a first valve body is provided on the first infusion tube. Purified liquid can be delivered into the cavity or discharged from the cavity through the first infusion tube. In addition, the bottom of the cavity is connected to a second infusion tube, and a second valve body is provided on the second infusion tube. Purified liquid can be delivered into the cavity or discharged from the cavity through the second infusion tube. The top of the cavity is connected to an exhaust pipe, and the waste gas in the cavity can be output through the exhaust pipe.

[0039] In addition, both the purification cylinder 11 and the mounting tube 15 are fitted with windows for observing the liquid level of the purification liquid.

[0040] It should be noted that, in one embodiment, the other end of the sleeve 12 is provided with a dust discharge port 12b, and the other end of the sleeve 12 is also provided with a control valve for opening or closing the dust discharge port 12b. When the control valve is opened, the dust accumulated at the bottom of the sleeve 12 can be discharged.

[0041] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
