[0003] The patent with publication number CN215725299U discloses a high-temperature waste gas treatment device. The water inside the water storage tank is introduced into the cooling pipe wound around the outer side of the ventilation pipe, and then re-introduced into the water storage tank from the other end of the cooling pipe. The motor installed on the cross plate in the cooling mechanism is started to drive the rotating shaft to rotate, driving the fan blades to rotate inside the circular groove, blowing air to cool the cooling pipe between the two groups of baffles, cooling the water flow passing through it, and flowing back into the water storage tank again, making the cooling effect better, so as to cool the high-temperature waste gas introduced into the connecting pipe and improve the efficiency of treating high-temperature waste gas. However, the following problems still exist in the actual use of this patent: Although this high-temperature waste gas treatment device cools the ventilation pipe through the spiral cooling pipe, the path of the spiral cooling pipe is fixed, and there is a certain gap between the spiral cooling pipes.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: For a cooling treatment device for high-temperature waste gas, the rotation of multiple spiral cooling pipes can not only make the spiral cooling pipes fully contact the surfaces of the shunt ventilation pipe and the second cooling pipe, enabling the shunt ventilation pipe and the second cooling pipe to be quickly cooled, thereby improving the heat exchange efficiency between the shunt ventilation pipe and the second cooling pipe and the high-temperature waste gas. The mixing rotating shaft and the mixing stirring rod are used to achieve the full reaction of the waste gas and the purification liquid, thereby improving the waste gas purification effect. The cleaning spiral blade can clean the precipitate generated by the purification to one side of the sewage valve, and the precipitate is discharged through the sewage valve. The specific content is as follows: 1. By setting a spiral cooling mechanism, the high-temperature waste gas is introduced into the first shunt. Under the action of the first shunt, the high-temperature waste gas is shunted into multiple airflows and enters the first intake pipe and the shunt ventilation pipe respectively. The first rotation motor is started to drive the first rotation worm to rotate. Taking advantage of the meshing connection between the first rotation worm and the first rotation worm gear, the first rotation worm gear drives the rotation main gear to rotate. Taking advantage of the meshing connection between the rotation main gear and the rotation slave gear, the rotation of the rotation slave gear is realized. At the same time, taking advantage of the meshing connection between the rotation slave gear and the first toothed ring, the revolution of the rotation slave gear is realized. At the same time, the rotation slave gear drives the water injection pipe and the spiral cooling pipe to rotate, making the spiral cooling pipe fit the surfaces of the shunt ventilation pipe and the second cooling pipe. At the same time, starting the circulating water pump can realize the circulation of the cooling water inside the fixed ring. The cooling water cools the shunt ventilation pipe and the second cooling pipe through the spiral cooling pipe. When the cooling water passes through the cooling circulation pipe, the cooling water inside the cooling circulation pipe can be cooled by an external cold air fan, thereby improving the cooling effect of the spiral cooling pipe. The rotation of multiple spiral cooling pipes can not only make the spiral cooling pipes fully contact the surfaces of the shunt ventilation pipe and the second cooling pipe, enabling the shunt ventilation pipe and the second cooling pipe to be quickly cooled, thereby improving the heat exchange efficiency between the shunt ventilation pipe and the second cooling pipe and the high-temperature waste gas. By shunting the high-temperature waste gas into several small airflows, the high-temperature waste gas is fully cooled without changing the flow rate of the high-temperature waste gas, thereby improving the high-temperature waste gas cooling effect; 2. By setting up the cooling and purification mechanism, not only can the air pump be used to pump the preliminarily cooled waste gas into the spray box through the second intake pipe and the rotating spray head, start the spray pump to pump the cooling water into the second rotating worm gear, and spray it through the spray pipe. By starting the second rotating motor to drive the second rotating worm to rotate, using the meshing connection between the second rotating worm and the second rotating worm gear, the second rotating worm gear drives the spray pipe to rotate, realizing the uniform spraying of water mist, enabling the water mist to fully contact the waste gas, thereby improving the cooling effect of the waste gas. The cooled waste gas enters the filter box through the connecting pipe, and the particulate matter and soot in the waste gas are filtered through multiple filter mesh plates. When the filter mesh plate is blocked, open the sealing cover through the handle, and remove the filter mesh plate through the mounting bracket. Under the action of the torsion spring hinge, the sealing cover can be closed, thereby cleaning and replacing the filter mesh plate. The filter mesh plate can be replaced without shutting down the machine, improving the filtering effect of the waste gas. Inject a certain amount of purification liquid into the purification box. Since the waste gas contains certain harmful substances, the corresponding purification liquid can be selected according to the content of harmful substances in the waste gas for purifying the waste gas. The height of the purification liquid is higher than the bottom of the injection pipe. At the same time, start the mixing motor to drive the cleaning spiral blade and the mixing rotating shaft to rotate. Using the meshing connection between the meshing gear and the stabilizing gear and the second toothed ring, the meshing gear can drive the mixing rotating shaft and the mixing stirring rod to rotate. Using the mixing rotating shaft and the mixing stirring rod, the waste gas and the purification liquid can react fully, thereby improving the waste gas purification effect. The cleaning spiral blade can clean the precipitate generated by purification to one side of the sewage valve, and discharge the precipitate through the sewage valve.

[0024] Working principle: Before using this device for cooling and treating high-temperature waste gas, it is necessary to first check the overall condition of the device to ensure that it can work normally. According to Figure 1 - Figure 11As shown in the figure, first, the high-temperature waste gas is introduced into the first diverter 104. Under the action of the first diverter 104, the high-temperature waste gas is diverted into multiple airflows and enters the first intake pipe 106 and the shunt vent pipe 114 respectively. Start the first rotating motor 109 to drive the first rotating worm 110 to rotate. Utilizing the meshing connection between the first rotating worm 110 and the first rotating worm wheel 111, the first rotating worm wheel 111 drives the rotating main gear 112 to rotate. Utilizing the meshing connection between the rotating main gear 112 and the rotating driven gear 116, the rotation of the rotating driven gear 116 is realized. At the same time, utilizing the meshing connection between the rotating driven gear 116 and the first toothed ring 124, the revolution of the rotating driven gear 116 is realized. At the same time, the rotating driven gear 116 drives the water injection pipe 117 and the spiral cooling pipe 118 to rotate, so that the spiral cooling pipe 118 fits the surfaces of the shunt vent pipe 114 and the second cooling pipe 123. At the same time, starting the circulating water pump 120 can realize the cooling water circulation inside the fixed ring 103. The cooling water cools the shunt vent pipe 114 and the second cooling pipe 123 through the spiral cooling pipe 118. When the cooling water passes through the cooling circulation pipe 122, the cooling water inside the cooling circulation pipe 122 can be cooled by an external cold air blower, thereby improving the cooling effect of the spiral cooling pipe 118. The rotation of multiple spiral cooling pipes 118 can not only make the spiral cooling pipes 118 fully contact the surfaces of the shunt vent pipe 114 and the second cooling pipe 123, enabling the shunt vent pipe 114 and the second cooling pipe 123 to be quickly cooled, thereby improving the heat exchange efficiency between the shunt vent pipe 114 and the second cooling pipe 123 and the high-temperature waste gas. By diverting the high-temperature waste gas into several small airflows, without changing the flow rate of the high-temperature waste gas, the high-temperature waste gas is fully cooled, thereby improving the cooling effect of the high-temperature waste gas.

[0025] Secondly, the air pump 202 is used to pump the preliminarily cooled waste gas into the spray box 201 through the second intake pipe 203 and the rotating spray head 204. The spray pump 207 is started to pump the cooling water into the second rotating worm gear 212 and spray it out through the spray pipe 213. By starting the second rotating motor 210 to drive the second rotating worm 211 to rotate, taking advantage of the meshing connection between the second rotating worm 211 and the second rotating worm gear 212, the second rotating worm gear 212 drives the spray pipe 213 to rotate, realizing the uniform spraying of water mist, enabling the water mist to fully contact the waste gas, thereby improving the cooling effect of the waste gas. The cooled waste gas enters the filter box 215 through the connecting pipe 216, and the particulate matter and soot in the waste gas are filtered by multiple filter mesh plates 220. When the filter mesh plates 220 are blocked, the sealing cover 218 is opened through the handle 219, and the filter mesh plates 220 are taken out through the mounting bracket 221. Under the action of the torsion spring hinge 217, the sealing cover 218 can be closed, thereby cleaning and replacing the filter mesh plates 220. The filter mesh plates 220 can be replaced without stopping the machine, improving the filtering effect of the waste gas.

[0026] Finally, a certain amount of purification liquid is injected into the purification box 224. Since the waste gas contains certain harmful substances, the corresponding purification liquid can be selected according to the content of harmful substances in the waste gas for the purification treatment of the waste gas. The height of the purification liquid is higher than the bottom of the injection pipe 223. At the same time, the mixing motor 226 is started to drive the cleaning spiral blade 227 and the mixing rotating shaft 228 to rotate. Taking advantage of the meshing connection between the meshing gear 230 and the stable gear 234 and the second toothed ring 225, the meshing gear 230 can drive the mixing rotating shaft 228 and the mixing stirring rod 229 to rotate. The full reaction between the waste gas and the purification liquid is realized by the mixing rotating shaft 228 and the mixing stirring rod 229, thereby improving the purification effect of the waste gas. The precipitate generated by the purification can be cleaned to one side of the sewage discharge valve 233 through the cleaning spiral blade 227, and the precipitate is discharged through the sewage discharge valve 233.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
