Description

High-efficiency energy-saving continuous blowdown flash vessel Technical Field The utility model relates to the technical field of blowdown flash vessels, in particular to a high-efficiency energy-saving continuous blowdown flash vessel. Background The continuous blowdown expansion vessel is also called a continuous blowdown expander, and the continuous blowdown expander is connected with a continuous blowdown outlet of the boiler and is used for decompressing and expanding continuous blowdown of the boiler. The boiler sewage is continuously and uniformly connected into a sewage discharge expansion vessel, the sewage is tangentially moved in a cylindrical partition plate in the middle part of the shell and immediately vaporized into secondary steam, the secondary steam is subjected to steam-water separation by a steam-water separator with a shutter at the upper part, then is introduced into a deaerator through an outlet at the top of the continuous row, and the remained sewage is discharged through a water level regulating valve. The boiler blow-down water is discharged into the blow-down container, particles in the sewage can enter the blow-down container together, the particles can remain in the blow-down container, and excessive particle residues can influence the sewage treatment. In view of the above, we propose a high-efficiency energy-saving continuous blowdown flash vessel. Disclosure of utility model The utility model aims to provide an efficient energy-saving continuous blowdown flash tank so as to solve the problems in the background technology. In order to achieve the aim, the utility model provides the technical scheme that the high-efficiency energy-saving continuous blowdown flash tank comprises a flash tank body, wherein a liquid inlet pipe is fixedly arranged at the liquid inlet end of the flash tank body, a connecting flange is arranged at the inlet end of the liquid inlet pipe, and the high-efficiency energy-saving continuous blowdown flash tank further comprises a filter pipe and a filter structure; The filter pipe is fixedly arranged between the liquid inlet pipe and the connecting flange; The filter structure is arranged in an annular groove formed in the filter pipe; The filtering structure comprises a fixed ring A and a filter screen; The fixed ring A is fixedly arranged on one side of the annular groove; The filter screen is fixedly arranged in the fixed ring A. Preferably, the filtering structure further comprises a fixed ring B, a movable ring and a supporting piece; the fixed ring B is fixedly arranged on the other side of the annular groove; the movable ring is movably arranged in the space between the fixed ring A and the fixed ring B; The connecting rod is arranged on the movable ring in a penetrating manner, two ends of the connecting rod are fixedly connected with the fixed ring A and the fixed ring B respectively, and a spring is sleeved on the connecting rod between the fixed ring B and the movable ring; the propping piece is fixedly arranged on the movable ring; Wherein, support the piece and contact the cooperation of filter screen.
