[0018] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0019] like Figure 1-Figure 2As shown, a high-temperature exhaust gas treatment spray tower with automatic water supply and drainage includes a spray tower body 1, which includes a shell 2. A water storage tank 5 is provided at the bottom of the shell 2. The water storage tank 5 and the shell 2 are connected with a spray mechanism 10, and the water in the water storage tank 5 is sprayed into the shell 2 through the spray mechanism 10. An air inlet 3 and an exhaust port 4 are provided on the shell 2. A ceramic filling layer is provided in the shell 2, and a return pipe 11 is provided at the bottom of the shell 2. The high-temperature exhaust gas enters from the air inlet 3, passes through the ceramic filling layer and mixes with the sprayed water. The sprayed water adsorbs dust particles in the high-temperature exhaust gas in the ceramic filling layer and reduces the temperature of the high-temperature exhaust gas. It flows back to the water storage tank 5 through the return pipe 11 at the bottom of the shell 2 to realize the recycling of water. The filtered exhaust gas is discharged from the exhaust port 4 to realize the entire high-temperature exhaust gas treatment process.

[0020] In detail, the water storage tank 5 is provided with a water inlet 6 and a water outlet 7, and the water inlet 6 is connected to a water supply system 8 to supply water to the water storage tank 5. The water outlet 7 is provided with a float valve 9, which can automatically control the liquid level of the water storage tank 5, is easy to maintain, flexible and durable, has high liquid level control accuracy, the water level is not affected by water pressure, and the opening and closing are tight and leak-proof.

[0021] In more detail, a filter plate 14 is also provided in the water storage tank 5. The filter plate 14 divides the water storage tank 5 into two areas, one is a reflux area for receiving high-temperature wastewater flowing out of the reflux pipe 11 on the shell 2, and the other is a filtering area for normal flowing water. The water outlet 7 is provided in the reflux area, and the water inlet 6 is provided in the filtering area. The filter plate 14 filters the water that flows back into the water storage tank from the shell 2, ensures that normal water flows into the water pump 15 in the filtering area, and prevents impurities from entering the water pump 15 or the spray pipe 16 and accumulating, causing the water pump 15 or the spray pipe 16 to be blocked, thereby affecting the spraying effect. In addition, since the filtering area is provided in the part of the water storage tank 5 extending out of the shell 2, and the filter plate 14 is detachably installed in the water storage tank 5, when too much filtered material is accumulated, it is convenient to clean or replace the filter plate 14 to ensure the filtering effect. During normal operation of the equipment, the water in contact with the high-temperature exhaust gas flows back to the water storage tank 5, causing the temperature of the circulating water to gradually increase. It is necessary to ensure the circulation of the water flow, open the water inlet 6 and the water outlet at the same time, and supply and drain water to the water storage tank 5 at the same time to ensure that the circulating water temperature is within the normal temperature range to avoid excessively high temperature affecting the high-temperature exhaust gas treatment effect.

[0022] In addition, a liquid level sensor is provided in the water tank 5. During operation, when the liquid level reaches a certain height, the liquid level sensor sends a signal to start the water pump 15 to pump water from the water tank 5 for spraying. When the liquid level is lower than a certain height, the liquid level sensor sends a signal to control the water supply system 8 to replenish the water tank 5.

[0023] In some embodiments, the spray mechanism 10 includes a spray pipe 16 disposed on the side wall of the housing 2 and a water pump 15 disposed in the filtering area. The spray pipe 16 includes an input pipe 17, a first output pipe 18 and a second output pipe 19. The water pump 15 delivers the filtered water into the input pipe 17, and the water flows through the first output pipe 18 and the second output pipe 19 and extends into the housing 2. The output ends of the first output pipe 18 and the second output pipe 19 are provided with spiral spray heads. The two output pipes can increase the spray area. At the same time, due to the provision of the spiral spray head, the spray area is further increased, and the cooling effect of the high-temperature exhaust gas and the adsorption of dust particles are enhanced. In addition, a butterfly valve 20 is provided between the input pipe 17 and the water pump 15, and the water switch can be controlled by the butterfly valve 20.

[0024] In some embodiments, the ceramic filling layer includes a plurality of ceramic ball rings, and the ceramic filling layer is formed by a plurality of ceramic ball rings. The ceramic ball rings can fully mix the incoming high-temperature exhaust gas with the sprayed water, so that the cooling and adsorption of dust particles are more significant. In addition, a door leaf 12 is also provided on the shell 2, and an observation window 13 is also installed on the door leaf 12. Through the observation window 13, the changes in the shell 2 can be better observed, and at the same time, it can be observed whether the ceramic ball rings are broken or blocked in a large area. By opening the door leaf 12, the ceramic ball rings in the shell 2 can be cleaned or replaced to ensure the effect of high-temperature exhaust gas treatment.

[0025] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
