Abstract

The invention relates to a continuous blowdown flash tank which comprises a vertical type cylinder body, wherein a sewage inlet and a manhole are formed in the cylinder body; a liquid level measuring device, a temperature meter and a pressure sampling tube are also arranged on the cylinder body; a pressure gauge is arranged on the pressure sampling tube; a top plate is arranged above the sewage inlet; a baffle extending downwards is connected to the top plate; two sides of the baffle are connected with the inner wall of the cylinder body; the sewage inlet is completely covered with the top plate and the baffle; and an abrasion-resistant plate is arranged on the inner wall of the cylinder body at the lower part on the same side of the sewage inlet. In a further improvement, the liquid level measuring device is a magnetic turning board type liquid level meter, and the pressure sampling tube is a stainless steel tube. Compared with the prior art, the liquid level measurement and the pressure measurement are more accurate, and the service life of the continuous blowdown flash tank is longer.

Description

technical field [0001] The invention relates to a boiler sewage discharge device, in particular to a continuous sewage discharge expander for expanding the capacity and reducing the pressure of the continuous sewage discharge of the boiler to separate water and vapor. Background technique [0002] Boiler blowdown expansion vessel includes regular blowdown blowdown expansion vessel and continuous blowdown expansion vessel. Continuous blowdown expansion vessel is to continuously discharge the furnace water with the highest salt concentration in boiler water from the steam drum, so as to keep the boiler water in good quality and produce Qualified steam. [0003] When the continuous sewage expansion vessel is working, the sewage enters from the water inlet, the water flow is sprayed along the tangential pipe, and the water film formed on the inner wall rotates downwards. Due to the centrifugal effect, a high-speed rotating water film skirt is formed at the pipe mouth, and the wa...
