Description

Technical Field

[0001] The utility model relates to the technical field of gasifier spray towers, in particular to a water return pipe structure based on a gasifier spray tower. Background Art

[0002] As the core part of the gas purification system, the gas generator spray tower carries the important mission of removing impurities and harmful substances in the gas, aiming to ensure the purity and safety of the gas. However, in actual operation, the problem of gas bubbles generated in the spray tower cannot be ignored. During the circulation process, these bubbles are likely to flow into the circulation pool along with the circulating water, leading to the hidden danger of gas leakage. The leaked gas not only directly affects the normal operation of the gas purification system and reduces the gas purification effect, but even worse, it may also pose a serious threat to the surrounding environment and operators. As a flammable and explosive gas, once leaked into the air, it is very easy to mix with oxygen in the air to form an explosive mixture. Once it encounters a fire source, it may cause a fire or explosion. In addition, long-term exposure to the gas environment may also cause health problems for operators due to inhalation of harmful gases.

[0003] The traditional spray tower return pipe structure does have many design deficiencies. First of all, the lack of effective gas isolation measures is the most prominent problem. During the flow of circulating water, gas bubbles can easily take the opportunity to mix in and enter the circulation pool along with the water flow. Secondly, the poor sealing performance of the return pipe is also a problem that cannot be ignored. Poor sealing will not only lead to gas leakage, but also may cause the circulating water to be contaminated, further affecting the gas purification effect.

[0004] In summary, the design defects of the return pipe structure of the gas generator spray tower and the gas leakage problem need to be solved urgently. This is not only related to the normal operation of the gas purification system, but also to the safety of the environment and operators. Therefore, we need to conduct in-depth research and exploration to seek a more reasonable and safe return pipe structure design solution to ensure the efficient and stable operation of the gas purification system.

[0005] The utility model aims to provide a water return pipe structure based on a gasifier spray tower to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A return water pipe structure based on a gas generator spray tower comprises a placement plate; a water reservoir is fixedly connected to one side of the placement plate, a cover plate is fixedly connected to the upper end of the water reservoir, a water treatment structure is fixedly connected to the upper end of the placement plate, the water treatment structure comprises a tower base, a bubble assembly and a bottom plate, the lower end of the tower base is fixedly connected to the upper end of the placement plate, the upper part of the tower base inner cavity is fixedly connected to the bubble assembly, the lower part of the tower base inner cavity is fixedly connected to the bottom plate, the upper end of the tower base is fixedly connected to a spray tower body, a spray assembly for spraying in the spray tower body is provided on one side of the spray tower body, a water outlet pipe is fixedly connected to the side of the tower base close to the water reservoir, and the inner cavity of the water outlet pipe is communicated with the inner cavity of the tower base, the output end of the water outlet pipe is fixedly connected to a water seal pipe, and the output end of the water seal pipe is fixedly connected to an exhaust structure.

[0008] A further improvement of the technical solution of the utility model is that the thorn bubble assembly includes a plurality of confluence blocks, and the plurality of confluence blocks are combined into a cylindrical shape. A stepped confluence groove is arranged between two adjacent confluence blocks, and a plurality of spike blocks are fixedly connected to the bottom wall of the inner cavity of the confluence groove.

[0009] The above-mentioned technical scheme is adopted, in which a confluence groove is provided, so that the spray water collected on the surface of the confluence block can flow downward through the confluence groove, and then the gas bubbles will flow in the inner cavity of the confluence groove together with the spray water, and then the gas bubbles can be punctured by a number of spike blocks in the inner cavity of the confluence groove, thereby reducing the number of gas bubbles carried by the spray water and reducing the leakage amount.

[0010] A further improvement of the technical solution of the utility model is that a plurality of cone thorn belts are fixedly connected to the upper end of the bottom plate, and each cone thorn is arranged at the outlet of the confluence trough, and there is a gap between the upper surface of the bottom plate and the confluence block.

[0011] By adopting the above technical solution, a cone-shaped thorn block is provided in the solution, so that the cone-shaped thorn block can be used to further puncture the gas bubbles in the inner cavity of the confluence trough that have not been punctured by a number of sharp thorn blocks, thereby further reducing the number of gas bubbles carried by the spray water.

[0012] A further improvement of the technical solution of the utility model is that the spray assembly includes a water pump, water pipe one and water pipe two, the water pump input end is fixedly connected to water pipe one, the water pump output end is fixedly connected to water pipe two, the upper part of water pipe two close to the spray tower body is fixedly connected to spray pipe one, and the middle part of water pipe two close to the spray tower body is fixedly connected to spray pipe two.

[0015] The above technical solution is adopted. In this solution, the water seal pipe is set in a U shape, so that when the horizontal height of the water outlet end of the water seal pipe is higher than the horizontal height of the water inlet end of the water seal pipe, a certain liquid level difference will be formed in the inner cavity of the water seal pipe, and the liquid level difference will generate a certain static pressure in the inner cavity of the water seal pipe, so that the water seal pipe can effectively prevent the reverse flow of gas. Then, in the circulating water system of the spray tower, if coal gas or other harmful gases try to enter the circulation pool through the water seal pipe, they must first overcome the static pressure in the inner cavity of the water seal pipe, so that harmful gases such as coal gas are effectively blocked outside the inner cavity of the water seal pipe, thereby ensuring the purity of the circulating water and the safety of the entire system.

[0017] The above-mentioned technical scheme is adopted, in which the water seal pipe and the transition pipe are coordinated so that the spray water can flow into the inner cavity of the return pipe through the transition pipe, and then flow back into the inner cavity of the water reservoir. Through the coordination of the water in the inner cavity of the water reservoir and the cover plate, a cover water seal can be formed on the end face of the water reservoir. Then, through the coordination of the air pipe structure and the transition pipe, some residual gas in the inner cavity of the water reservoir can be discharged into the sky through the air pipe structure, so that there is no residual gas in the station.

[0018] A further improvement of the technical solution of the utility model is that the air pipe structure includes a connecting pipe, an anti-blocking block is fixedly connected to the upper end of the connecting pipe, a gap exists between the connecting pipe and the inner wall of the anti-blocking block, and a plurality of air outlet holes are opened on the upper part of the connecting pipe.

[0019] The above technical solution is adopted, in which an anti-blocking block is provided, so that the connecting pipe and the air outlet can be protected by the anti-blocking block, so as to prevent dust and some garbage floating in the air such as leaves, plastic bags, etc. from clogging the air outlet, thereby affecting the gas discharge of the air pipe structure.

[0020] A further improvement of the technical solution of the utility model is that the bracket structure includes a connecting rod, a plurality of fixing blocks are fixedly connected to one side of the connecting rod close to the trachea structure, the inner cavity of the fixing block is tightly fitted with the outer surface of the connecting pipe, the lower end of the connecting rod is fixedly connected to a supporting block, and the lower end of the supporting block is fixedly connected to the upper end of the cover plate.
