[0002] As environmental protection requirements continue to increase, the current terminal treatment method for waste gas and wastewater containing organic matter generally adopts high-temperature incineration. The sulfur, chlorine and other elements contained in the organic matter are eventually burned into acidic substances such as sulfide and chloride. The exhaust of the incineration equipment is high-temperature flue gas (800-1200℃). This type of waste gas has the characteristics of strong corrosiveness and high temperature. The high-temperature flue gas needs to be deacidified before it can be discharged. The conventional treatment methods are flue gas cooling and flue gas deacidification.

[0003] A search of the Chinese patent publication number CN209405985U discloses an exhaust gas cooling tower, which relates to the technical field of exhaust gas treatment. Its key technical features include: a tower body, an air inlet located at the bottom of the tower body, an exhaust port located on the top wall of the tower body, and a cooling assembly located at the bottom of the tower body cavity. The tower body has a rectangular horizontal cross-section. A filter assembly is located within the tower body cavity above the cooling assembly. The filter assembly includes a movable frame that slides horizontally to the side wall of the tower body, a filter frame that snaps onto the movable frame, and activated carbon placed within the filter frame. The tower body side wall has an escape slot for the movable frame to slide out. This utility model has the effect of both cooling exhaust gas and removing irritating odors from the exhaust gas.

[0004] Existing exhaust gas cooling towers operate through refrigerators or heat exchangers, which results in high equipment costs. Furthermore, refrigerators and heat exchangers are prone to malfunction when operated in a long-term corrosive environment, making them inconvenient to use. Utility Model Content

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] like Figure 1-3As shown, the utility model provides a constant temperature cooling tower, including a tower body 1, which is sequentially provided with an air inlet section 11, a high temperature section 12, a medium and low temperature section 13 and an air outlet section 14 from top to bottom. The air inlet section 11 and the high temperature section 12 are an integrated structure, and the medium and low temperature section 13 and the air outlet section 14 are an integrated structure. An atomizing double-fluid nozzle 2 is provided on the side wall of the air inlet section 11, and a connecting point between the high temperature section 12 and the medium and low temperature section 13 is provided with a docking ring 5. The docking ring 5 is threadedly connected with a bolt, and the bolt is threadedly connected to one side of the tower body 1. The docking ring 5 and the tower body 1 are detachably connected by bolts. The openings at both ends of the air inlet section 11 are small at the top and large at the bottom, and the openings at both ends of the air outlet section 14 are large at the top and small at the bottom. By providing the air inlet section 11 with a small top and large bottom shape, the flow rate of the exhaust gas entering the high temperature section 12 can be reduced so that it can be connected with the mist The water mist particles sprayed by the atomizing dual-fluid nozzle 2 are in full contact with heat exchange. On the contrary, the air outlet section 14 with a larger upper portion and a smaller lower portion can increase the outlet flow rate of the cooled exhaust gas and improve the processing efficiency of the equipment. A disassembly mechanism 4 is provided between the atomizing dual-fluid nozzle 2 and the tower body 1. A spoiler ring 3 is provided on the inner wall of the medium and low temperature section 13. The disassembly mechanism 4 includes a mounting plate 41. The mounting plate 41 is connected to the atomizing dual-fluid nozzle 2. A connecting block 42 is fixedly connected to one side of the tower body 1. A slide groove 43 is provided on the connecting block 42. A slider 44 is slidably connected in the slide groove 43. A spring 45 is fixedly connected to the top of the slider 44. A first bolt 46 is threadedly connected to the slider 44. The first bolt 46 is provided with an anti-slip thread. This arrangement prevents the first bolt 46 from sliding during the disassembly process. The first bolt 46 is threadedly connected to the tower body 1.

[0027] In this embodiment, the first bolt 46 is provided with an anti-slip thread, which prevents the first bolt 46 from sliding during the disassembly process. A docking ring 5 is provided at the connecting point between the high-temperature section 12 and the medium and low-temperature sections 13. The docking ring 5 is threaded with a bolt, and the bolt is threadedly connected to one side of the tower body 1. The docking ring 5 and the tower body 1 are detachably connected by bolts. The openings at both ends of the air inlet section 11 are small at the top and large at the bottom, and the openings at both ends of the air outlet section 14 are large at the top and small at the bottom. By setting the air inlet section 11 with a small top and large bottom shape, the flow rate of the exhaust gas entering the high-temperature section 12 can be reduced, so that it can fully contact and exchange heat with the water mist particles sprayed by the atomizing two-fluid nozzle 2. On the contrary, the air outlet section 14 with a large top and small bottom shape can increase the outlet flow rate of the cooled exhaust gas, thereby improving the processing efficiency of the equipment.

[0028] The following is a detailed description of the working principle of this constant temperature cooling tower.

[0029] like Figure 1-3As shown, when in use, high-temperature exhaust gas enters the high-temperature section 12 through the air inlet section 11 of the tower body 1, and the atomizing dual-fluid nozzle 2 is used to spray water mist particles to cool the exhaust gas. At the same time, the spoiler ring 3 in the medium and low temperature section 13 can reduce the flow rate of the exhaust gas in the high-temperature section 12, so that it can fully contact and exchange heat with the water mist particles, thereby cooling the exhaust gas. The cooled exhaust gas is naturally cooled in the medium and low temperature section 13 of the tower body 1 and then discharged through the air outlet section 14 into the next-level treatment equipment. The installation and replacement cost of the atomizing dual-fluid nozzle 2 is low, and it can play a good cooling role for the exhaust gas and is easy to use. When installing the atomizing dual-fluid nozzle 2, remove the first bolt 46 to separate the mounting plate 41 from the tower body 1, thereby realizing the disassembly of the atomizing dual-fluid nozzle 2. During installation, the spring 45 will drive the slider 44 to contact the mounting plate 41, thereby realizing the pre-positioning of the mounting plate 41, thereby facilitating the installation of the atomizing dual-fluid nozzle 2 and facilitating the replacement and daily maintenance of the atomizing dual-fluid nozzle 2.
