Description

Technical Field

[0001] The utility model relates to the technical field of desuperheaters, in particular to an energy-saving desuperheater. Background Art

[0002] A desuperheater is a device that uses water as a cooling medium to regulate the temperature of superheated and reheated steam. Its function is to control and maintain the superheated steam temperature or reheated steam temperature at a specified value and to prevent the superheater and reheater tube walls from being heated. Desuperheaters are divided into two types: surface type and water spray type.

[0003] The patent with the publication number CN219933952U discloses a water spray cooler, which relates to the technical field of boiler cooling. The water spray cooler includes a machine, the upper surface of the machine is fixedly connected with a boiler, the right wall of the boiler is penetrated and fixedly connected with a cooling pipe, the right wall of the cooling pipe is penetrated and fixedly connected with a water inlet pipe, the left end of the water inlet pipe is fixedly connected with a flange, the left surface of the flange is fixedly connected with a water suction pipe, the middle section of the water suction pipe is provided with a water pump, the tail end of the water suction pipe is fixedly connected with a water storage tank, and the rear surface of the water inlet pipe is fixedly connected with a nozzle. The utility model uses a water pump to extract the cooling water in the water storage tank, and sprays it in the cooling pipe through the nozzle to cool the steam. The cooling water will be pushed by the steam, and will be blocked when flowing through the water storage tank and enter the water storage tank through the water outlet pipe. Through such a device, the cooling water can be recycled, which reduces the waste of resources and reduces the cost of work.

[0004] During use, the above-mentioned desuperheater can recycle the cooling water after use to save resources, but after long-term use, the cooling water that absorbs heat will mix with the cooling water in the water tank, causing its temperature to gradually increase, thereby affecting the cooling effect and efficiency of the steam, and more cooling water needs to be sprayed to cool it down; in addition, when spraying cooling water, since the cooling water is not filtered, this is likely to cause impurities to remain in the cooling water. If used for a long time, scale will form on the pipe wall and impurities will remain in the desuperheated water. Utility Model Content
