Currently, spray towers are generally used in TFT glass furnace flue gas treatment equipment to treat and optimize the flue gas from TFT glass furnaces, thereby ensuring that the flue gas meets emission standards before discharge. If the pipes in the spray tower are blocked, it will directly affect production and cause flue gas emissions to fail to meet standards, affecting overall operations.

[0003] Currently, if a blockage occurs in the spray tower, the water nozzles and spraying conditions inside the spray tower may not be discovered in time by maintenance personnel during operation. Even if maintenance personnel discover that the water nozzles in the spray tower are blocked, they need to switch equipment and enter the spray tower to replace the water nozzles and water inlet pipes. If only the water nozzles are replaced, they can simply remove them and replace them. However, if the blockage is in the water inlet pipe and the spray tower cannot be cleared, the water inlet pipe must be cut out and remade to repair it. This will cause time-consuming and laborious maintenance problems. In addition, due to the gas cutting and welding in a confined space, it poses a great safety hazard to maintenance personnel. Therefore, in summary, the current spray towers for TFT glass furnace flue gas treatment have the problem that the water nozzles and spraying conditions in the spray tower may not be discovered in time by maintenance personnel, and the maintenance work for blocked water inlet pipes is relatively time-consuming and laborious.

[0031] How to optimize the spray tower used for TFT glass furnace flue gas treatment so that it can be easily observed and detected by maintenance personnel, and facilitate maintenance and overhaul.

[0032] Based on this, Figure 1 As shown, the utility model provides a spray tower for treating flue gas from a TFT glass furnace, comprising a spray tower body, the spray tower body comprising a spray cavity, the spray cavity being provided with a flue gas inlet 13 and a flue gas outlet 14, the spray cavity having a spray assembly and an observation portion; wherein:

[0033] The spray assembly can be connected to an external water supply device so that the spray assembly can spray in the spray cavity;

[0034] The spray assembly includes a plurality of spray units, each of which includes a plurality of water inlet pipes 12, each of which is disposed in the spray cavity via a detachable member; the portion of the water inlet pipe 12 located in the spray cavity has at least one nozzle 11;

[0035] The spray cavity is provided with an observation port 1 , and the observation part is arranged at the observation port 1 , and the observation part includes a transparent observation plate arranged at the observation port 1 .

[0036] like Figure 1 As shown, in some embodiments, the present invention changes the number of water inlet pipes 12 on each layer in the spray tower from one to three, so as to improve the efficiency and quality of its flue gas treatment, and each water inlet pipe 12 is supplied with water through an external water supply device, and the water supply device has an independent valve for controlling each water inlet pipe 12. As a specific embodiment, the water inlet pipe 12 is connected to the external water inlet pipe with a hose, and the valve of the water inlet pipe is used for independent control. The utility model is a spray tower for TFT glass kiln flue gas treatment, in which the spray assembly is composed of a plurality of spray units, each spray unit includes a plurality of water inlet pipes 12, and each water inlet pipe 12 is equipped with at least one nozzle 12. The passage design of multiple water inlet pipes 12 can ensure the uniformity and extensiveness of the spraying, thereby improving the efficiency and quality of flue gas treatment. In combination with the utility model, the water supply pipe 12 supplies water through an external water supply device, and the water supply device is equipped with an independent valve for each water inlet pipe 12, so that when repairing a certain water inlet pipe 12, its valve can be closed without affecting the operation of other water inlet pipes 12, thereby improving the reliability and flexibility of the entire spray tower.

[0037] As a preferred embodiment, in a specific embodiment, the utility model is a spray tower for treating flue gas from a TFT glass furnace. A water inlet pipe flange seat 9 can be fixedly connected to the side wall of the spray tower (welding is optional), and a water inlet pipe flange 10 is mounted on the water inlet pipe 12. The water inlet pipe flange 10 and the water inlet pipe 12 can also be welded together. During inspection and maintenance by the operator, the water inlet pipe flange 10 is removed from the water inlet pipe flange seat 9 and pulled out of the spray tower together with the water inlet pipe 12. The holes in the water inlet pipe 12 on the side wall of the spray tower are then blocked to prevent external air from entering and causing fluctuations in the furnace pressure. After maintenance or replacement of the water inlet pipe 12 or the nozzle 11, the water inlet pipe 12 is inserted into the spray tower and the water inlet pipe flange 10 is connected to the water inlet pipe flange seat 9 to complete the maintenance and replacement of the water inlet pipe 12. Each water inlet pipe 12 of the present invention is arranged on the spray cavity through the above-mentioned flange connection or other detachable parts, so that it can be easily disassembled and installed when repairing or replacing the spray unit, reducing the difficulty and time of maintenance work, thereby improving the efficiency of the operation.

[0038] As a specific embodiment, the transparent observation plate can be made of quartz glass 6. The flange cover plate 4 of the present invention has a square hole formed on it, a slide groove 7 welded to it, and a sealing gasket 8 bonded around the square hole. Threaded holes are machined in the slide groove 7, and tightening bolts 5 are installed in the threaded holes of the slide groove 7. The quartz glass 6 covers the square hole of the flange cover plate 4, and the sealing gasket 8 acts as a seal between the quartz glass 6 and the flange cover plate 4. The spray chamber of the present invention is provided with an observation port 1 and a transparent observation plate (in some embodiments, quartz glass 6 may be used, but is not limited to being used). This allows maintenance personnel to directly observe the spraying conditions and promptly detect and address problems such as nozzle blockage. The observation port 1 also serves as an entry and exit for maintenance personnel. When maintenance personnel need to enter, they can remove the sealing portion of the observation port 1 to enter for detailed processing and maintenance. The present invention provides a compressed air inlet pipe at the observation port location. During routine inspection and maintenance work, it can be used to clear water droplets and other impurities from the observation plate, effectively ensuring the clarity of observation for maintenance personnel, improving work quality, and reducing unnecessary disassembly and installation.

[0039] The utility model welds a compressed air inlet pipe 2 at the position of the observation port 1 corresponding to the quartz glass 6. The compressed air inlet pipe 2 is connected to an external air supply device, which can blow air into the quartz glass 6 to remove water droplets thereon, making it easier for maintenance personnel to observe. If a hose is connected to the compressed air port 2, compressed air can be passed in during observation to clear water droplets from the quartz glass 6, ensuring the transparency of the quartz glass 6 and improving the quality of the work.

[0040] As a specific embodiment, the utility model provides a spray tower for TFT glass furnace flue gas. During routine inspection, maintenance personnel turn on the compressed air to clean the surface of the quartz glass, and use a flashlight to observe the spraying condition of the nozzle through the quartz glass, if a nozzle blockage problem is found.

[0041] Remove the bolts connecting the water inlet pipe flange to the water inlet pipe flange seat, remove the water inlet pipe and nozzle, and clean and unclog the nozzle on the water inlet pipe. Plugging the hole in the removed water inlet pipe prevents outside air from entering and causing fluctuations in furnace pressure. Once cleaned, install the nozzle directly on the water inlet pipe 12. Insert the water inlet pipe 12 into the water inlet pipe flange seat 9 and connect the water inlet pipe flange seat 9 to the water inlet pipe flange 10. This resolves the problem of nozzle and water inlet pipe blockage.

[0042] like Figure 2 As shown, in some preferred embodiments, the utility model is a spray tower for TFT glass furnace flue gas, the observation port 1 is provided with a flange assembly, the flange assembly has an opening, and the transparent observation plate 14 is provided on the flange assembly through a fastening assembly. The flange assembly includes an inlet flange 3 and a flange cover plate 3 provided thereon, and the flange cover plate 4 has an opening. The fastening assembly includes two slide grooves 7 provided on the flange cover plate 4, and the transparent observation plate can be clamped between the two slide grooves 7, and each slide groove 7 is provided with a fastening screw 5. A sealing gasket 8 is provided between the slide groove 7 and the fastening screw 5. When the water inlet pipe 12 is disassembled for maintenance, the utility model can avoid fluctuations in the furnace pressure caused by the maintenance operation process to a certain extent. At the same time, the good sealing between the observation plate and the spray chamber is ensured by the design of the slide groove 7, the sealing gasket 8 and the tightening bolt 5. It is convenient to disassemble and assemble, and convenient for maintenance personnel to enter and exit.

[0043] In summary, the present invention provides a spray tower for treating flue gas from a TFT glass furnace.
