Abstract

The invention discloses a cleaning device for a continuous blowdown expander. The cleaning device comprises a cavity. Cleaning water inlet pipes are arranged on the lower portion of the cavity and are of a tangential oblique inserting pipe type structure. A cavity opening is formed in the connecting portions of the cleaning water inlet pipes and the cavity. The multiple cleaning water inlet pipes are uniformly distributed and arranged in the axial direction of the cavity opening. The cleaning water inlet pipes on the two sides of the cavity are arranged in a staggered manner. A flow division adjusting device is arranged at the cavity opening and is used for dividing cleaning water in the cleaning water inlet pipes in the wall face direction of the cavity. According to the cleaning device, as the cleaning water inlet pipes are arranged in the staggered manner and the flow division adjusting device is used in cooperation, the flushing amount loss of cleaning water is small, the cleaning effect is remarkable, lasting time is short, water resources are saved, the defects of an existing cleaning device are overcome, the cleaning device can adapt to cleaning of multiple dirt grains, adaptability and pertinence of the cleaning device are improved, and then the function of the cleaning device tends to be diversified.

Description

technical field

[0001] The invention relates to the field of boiler blowdown equipment, in particular to a cleaning device for a continuous blowdown expander. Background technique

[0002] The continuous blowdown expander is also called the continuous blowdown expander. Its function is to separate the steam and sewage at the boiler blowdown expansion evaporation place. The separated steam can be recycled to the thermal system, and the unevaporated blowdown water can be sent to the blowdown Cooler to heat softened water etc. The continuous blowdown expander uses the principle of flash evaporation to obtain secondary steam. The boiler blowdown water with certain parameters is suddenly input from the pipeline into the expander whose volume is several times larger than the pipeline. The pressure decreases and the volume increases, thereby flashing The steam evaporates. The continuous sewage discharger relies on ion separation, gravity separation and molecular friction separati...
