These exhaust gases contain a large amount of harmful particles such as sulfide and nitrogen oxides, which pose a threat to the environment and human health. Therefore, high-temperature exhaust gas treatment is of great significance to protecting the environment and human health.

[0003] Most of the existing high-temperature exhaust gas treatment equipment only focuses on the heat recovery of high-temperature exhaust gas. For example, in the Chinese utility model patent entitled "A high-temperature exhaust gas recycling exhaust gas treatment device" with publication number CN218924211U, although the heat can be recovered, the harmful substances contained in the high-temperature exhaust gas are not treated immediately. The harmful substances may leak in the heat recovery mechanism and when transferred between the heat recovery mechanisms. In the end, only the filter plate and the activated carbon fiber filter are used for simple physical adsorption filtration, which has a very poor treatment effect on the harmful substances and poses a great harm to the nearby environment and operators. Therefore, a high-temperature exhaust gas treatment equipment is needed to address the above problems. Utility Model Content

[0013] 1.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 The utility model provides a technical solution: a high-temperature exhaust gas treatment equipment, including a treatment box 1, a sewage pipe 2, an air intake pipe 3, a diffusion bucket 4, a dispersion net 5, a water supply pipe 6, an atomizing nozzle 7, a dosing pipe 8, a servo motor 9, a horizontal shaft 10, a stirring fan blade 11, a transfer pipe 12, a substrate 13, an adsorption cylinder 14, an adsorption filler 15 and an exhaust pipe 16. The bottom end of the treatment box 1 is provided with a sewage pipe 2, and the top of one side of the treatment box 1 is fixed with an air intake pipe 3, a diffusion bucket 4 is installed at the end of the air intake pipe 3, and a dispersion net 5 is fixedly installed at the end of the diffusion bucket 4. The diameter of the end of the diffusion bucket 4 where the dispersion net 5 is installed is greater than twice the diameter of the air intake pipe 3. The center of the diffusion bucket 4 and the center of the treatment box 1 are on the same vertical plane. The above structural design allows the high-temperature gas to diffuse over a large area toward the water supply pipe 6 and the atomizing nozzle 7 through the diffusion bucket 4 and the dispersion net 5, so that the harmful substance particles in the high-temperature gas can contact with the water mist over a large area;

[0022] When using the device, water is first supplied to the water supply pipe 6 through the water pump connected to the water supply pipe 6, and clean water is sprayed from the atomizing nozzle 7 to form dense water mist in the treatment box 1. Then, the high-temperature exhaust gas is input through the air inlet pipe 3, and the high-temperature exhaust gas passes through the Figure 2 The diffusion bucket 4 and the dispersion net 5 in the exhaust gas diffuse over a large area toward the water supply pipe 6, and the harmful particles in the high-temperature exhaust gas come into contact with the dense water mist over a large area. The water mist adsorbs the harmful particles and immediately condenses and drips on the bottom of the inner side of the treatment box 1;

[0023] On the top of the inner side wall and the inner top wall of the treatment tank 1, a water supply pipe 6 is provided. Atomizing nozzles 7 are fixedly installed on the water supply pipe 6. The water supply pipes 6 are densely distributed at equal intervals. The side view shape of the water supply pipe 6 is in the shape of "冖". The distance between adjacent water supply pipes 6 is not greater than 3 times the diameter of the water supply pipe 6. The above structural design enables the water supply pipe 6 and the atomizing nozzles 7 to cooperate to form a dense water mist on the inner top of the treatment tank 1. Atomizing nozzles 7 are installed on both the vertical part and the horizontal part inside the water supply pipe 6. The atomizing nozzles 7 are densely distributed at equal intervals. The above structural design ensures the density of the sprayed water mist, enabling the water mist to efficiently adsorb harmful substance particles in the high-temperature gas and immediately aggregate and condense and fall, facilitating subsequent chemical treatment;

[0024] When the water converged at the inner bottom of the treatment tank 1 reaches a certain amount, reaction chemicals are first added through the chemical addition pipe 8, and the servo motor 9 is started to drive the horizontal shaft 10 and the stirring fan blades 11 to rotate stably. The reaction chemicals react with the reactable harmful substance particles in the water. Subsequently, flocculating chemicals are added through the chemical addition pipe 8 to flocculate the non-reactable harmful substance particles and the residues obtained from the reaction. Then the servo motor 9 is turned off and left to settle. The sewage discharge pipe 2 is opened, and the flocculated sludge is first discharged until clear liquid starts to be discharged. The sewage discharge pipe 2 is temporarily closed, and the bottom end of the sewage discharge pipe 2 is connected to the heat recovery mechanism to discharge the clear liquid with a certain temperature for heat recovery;

[0025] In the middle of the top end of the treatment tank 1, the chemical addition pipe 8 is fixedly installed through. On the other side of the bottom of the treatment tank 1, a servo motor 9 is fixed. The output end of the servo motor 9 is equipped with a horizontal shaft 10. Stirring fan blades 11 are fixed on the horizontal shaft 10. The horizontal shafts 10 are symmetrically distributed about the center of the treatment tank 1. Stirring fan blades 11 are densely installed on the horizontal shafts 10 at equal intervals. The diameter of the stirring fan blades 11 is not less than 1 / 3 of the inner width of the treatment tank 1. The above structural design enables the horizontal shaft 10 and the stirring fan blades 11 to fully stir the water body containing harmful substance particles and the chemicals when rotating, ensuring the reaction effect and flocculation effect on the harmful substance particles. On the other end of the top of the treatment tank 1, a transfer pipe 12 is installed through;

[0026] The end of the transfer pipe 12 is installed through the center of the substrate 13. The substrate 13 is fixedly connected to one end of the adsorption cylinder 14. Adsorption packing 15 is installed in the adsorption cylinder 14. The other end of the adsorption cylinder 14 is fixedly installed with an exhaust pipe 16. The above structural design enables the adsorption packing 15 to perform secondary adsorption treatment on the exhaust gas after primary treatment, improving the treatment effect. At the same time, the substrate 13 and the adsorption cylinder 14 can be conveniently disassembled, facilitating the cleaning or replacement of the adsorption packing 15. The diameter of the substrate 13 is equal to the inner diameter of the adsorption cylinder 14. Half of the length of the adsorption cylinder 14 is less than the length of the adsorption packing 15. The above design can prevent exhaust gas leakage and ensure the adsorption effect of the adsorption packing 15 on the exhaust gas;

[0027] The treated gas is discharged into the adsorption cylinder 14 through the transfer pipe 12, adsorbed again by the adsorption filler 15, and finally discharged through the exhaust pipe 16. The substrate 13 and the adsorption cylinder 14 can be disassembled and separated regularly, and the adsorption filler 15 can be cleaned or replaced.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
