Description

Technical Field

[0001] The utility model relates to the technical field of waste gas cooling towers, in particular to a waste gas cooling tower for a thermal power plant. Background Art

[0002] Waste gas usually refers to harmful gases discharged by humans during the production process. Thermal power plants will produce a large amount of waste gas during the power generation process. This waste gas generally contains a large amount of heat. If this waste gas with a large amount of heat is directly discharged into the air, it will aggravate the pollution to the environment. Therefore, before discharging the waste gas, the waste gas needs to pass through the waste gas cooling tower to cool the waste gas before discharging it.

[0003] Existing exhaust gas cooling towers generally cool exhaust gas by spraying water and through heat exchange, but generally only a spray device is installed above the exhaust pipe. When the exhaust pipe is sprayed to cool it down, only the upper part of the exhaust pipe can be effectively cooled down, and the lower part of the exhaust pipe still maintains a higher temperature, which reduces the cooling efficiency.

[0004] Therefore, we propose a waste gas cooling tower for a thermal power plant to solve the above-mentioned problems. Utility Model Content

The coolant in the first pipe 8 and the second pipe 9 can be sprayed out through the first nozzle 801 and the second nozzle 901, so as to cool the exhaust gas pipe 10, so as to improve the cooling efficiency.

[0026] The bottom of the tower body 1 is set to be conical, and the bottom of the tower body 1 is connected to the top of the water tank 5 through a downpipe 12. A water inlet is set on the top of the water tank 5, so that the coolant at the bottom of the tower body 1 can return to the water tank 5 through the downpipe 12, which is convenient for the recycling of the coolant.

[0027] A plurality of first pipes 8 are arranged in parallel inside the tower body 1, and the first pipe 8 is located below the fan blades 301.
