Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste gas spray tower technology, and more specifically, to a spray structure of a waste gas spray tower. Background Technology
[0002] Spray towers exist as a type of environmental waste gas treatment equipment. Based on their working principle, they are divided into circulating water spray towers, alkaline spray towers, and acid spray towers (also known as pickling towers). Based on the tower body material, they are divided into fiberglass spray towers, PP spray towers, and stainless steel spray towers. The appropriate spray material and spray process are selected according to the different properties of the waste gas.
[0003] Current spray towers typically use a ring-shaped pipe and spray heads to spray water mist downwards, which reacts with and settles harmful substances and dust in the exhaust gas. However, this structure results in a faster flow rate of the smoke, which can easily lead to incomplete spraying reactions. Utility Model Content
[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a spray structure for an exhaust gas spray tower, so as to solve the problem that the spray reaction is not thorough due to the fast flow speed of the smoke in the existing spray tower.
[0005] To achieve the above objectives, the present invention adopts the following technical solution;

[0007] As a further description of the above technical solution: the spray pipe is inclined along the inner wall of the conical hood, and spray heads arranged at equal intervals are fixedly installed on the spray pipe.
[0008] As a further description of the above technical solution: the filtration mechanism includes a locking block and two filter screens. The bottom of the locking block is engaged with the top of the filter box, the top of the filter screens is inserted into the interior of the locking block, and the bottom of the filter screens is engaged with the inner wall of the filter box.
[0009] As a further description of the above technical solution: a positioning frame is fixedly installed on the right side of the main body of the spray tower, and a vertical cylinder is fixedly installed on the positioning frame. The bottom end of the vertical cylinder is fixedly connected to the locking block.
[0010] As a further description of the above technical solution: a drain valve pipe is fixedly installed at the bottom left side of the main body of the spray tower.
[0011] As a further description of the above technical solution: control valves are fixedly installed on the outer sides of both horizontal ends of the three-way pipe.
[0012] Compared with existing technologies, the advantages of this utility model are:
[0013] This solution reduces the space for waste gas to pass through inside the spray tower by setting a conical hood, thereby enabling the device to utilize the conical structural design to extend the flow time of waste gas and make the spray reaction effect more complete.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;
[0021] Please see Figures 1-4 In this utility model, a spray structure of a waste gas spray tower includes a spray tower body 1, a smoke exhaust pipe 2 fixedly installed on the top of the spray tower body 1, an air inlet pipe 3 fixedly installed on the left side of the spray tower body 1, a filter screen 4 fixedly installed inside the spray tower body 1, a filter box 5 fixedly installed on the right side of the spray tower body 1, a filter mechanism 6 installed inside the filter box 5, a circulation pump 7 fixedly installed on the right side of the filter box 5, a three-way pipe 8 fixedly connected to the input end of the circulation pump 7, the left end of the three-way pipe 8 passing through and fixedly installed inside the filter box 5, a water tower 9 fixedly connected to the other end of the three-way pipe 8, a diversion pipe 10 fixedly connected to the output end of the circulation pump 7, the other two ends of the diversion pipe 10 passing through and fixedly installed inside the spray tower body 1, a conical cover 11 fixedly installed at the other two ends of the diversion pipe 10, four evenly distributed spray pipes 12 fixedly installed inside the conical cover 11, and the top ends of the four spray pipes 12 communicating and fixedly connected to the inside of the diversion pipe 10.
[0022] In this invention, the spray tower body 1 serves as the main body of the device. First, exhaust gas is introduced into the interior of the spray tower body 1 through the air inlet pipe 3. Simultaneously, the circulation pump 7 is activated to extract water from the water tower 9, which is then injected into the spray pipes 12 inside the two conical hoods 11 through the diversion pipe 10. This forms a downward spray that covers the bottom space of the conical hoods 11, treating the rising exhaust gas. Because the conical hoods 11 reduce the upward flow space of the exhaust gas inside the spray tower body 1, the flow velocity of the smoke inside the spray tower body 1 decreases, creating vortices sequentially inside the two conical hoods 11. This design allows for more thorough spraying, and the sprayed water mist accumulates at the bottom of the spray tower body 1 and enters the filter box 5. The filtered water is then recycled and reused continuously. This design utilizes a conical structure to extend the flow time of the exhaust gas, resulting in a more thorough spraying reaction. It solves the problem in existing technologies where a ring-shaped pipe and spray head are used to spray water mist downwards to react with and settle harmful substances and dust in the exhaust gas. However, this structure results in a faster flow of smoke, which can lead to incomplete spraying.
[0023] Please see Figure 3 and Figure 4 The spray pipe 12 is inclined along the inner wall of the conical cover 11, and spray heads 13 arranged at equal intervals are fixedly installed on the spray pipe 12.
[0024] In this invention, the spray pipe 12 is inclined along the inner wall of the conical hood 11 and works with the spray head 13 to spray the lower part of the conical hood 11, thereby achieving a thorough spraying reaction on the passing exhaust gas and ensuring the treatment effect.
[0025] Please see Figure 2The filter mechanism 6 includes a locking block 61 and two filter screens 62. The bottom of the locking block 61 is locked to the top of the filter box 5, the top of the filter screens 62 is inserted into the inside of the locking block 61, and the bottom of the filter screens 62 is locked to the inner wall of the filter box 5.
[0026] In this invention, the filter screen plate 62 is installed by the locking block 61, so that it can filter the sewage inside the filter box 5 and is easy to disassemble and replace.
[0027] Please see Figure 2 The spray tower body 1 has a positioning frame 14 fixedly installed on its right side, and a vertical cylinder 15 fixedly installed on the positioning frame 14. The bottom end of the vertical cylinder 15 is fixedly connected to the locking block 61.
[0028] In this utility model, the vertical cylinder 15 on the positioning frame 14 drives the locking block 61 and the filter screen 62 to rise and fall vertically, thereby realizing the installation and separation from the filter box 5, which facilitates the subsequent replacement of the filter screen 62.
[0029] Please see Figure 1 and Figure 2 Among them, a drain valve pipe 16 is fixedly installed at the bottom left side of the main body 1 of the spray tower.
[0030] In this invention, the sludge filtered from the bottom of the spray tower body 1 is conveniently discharged through the drain valve pipe 16.
[0031] Please see Figure 1 and Figure 2 Among them, control valves 81 are fixedly installed on the outer sides of both horizontal ends of the three-way pipe 8.
[0032] In this invention, the connection between the three-way pipe 8, the filter box 5, and the water tower 9 is conveniently controlled by the control valve 81, so as to facilitate the control of the connection of the circulating water circuit.
[0033] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
