The invention discloses a sewage drainage energy-saving flash tank, which comprises a shell, a steam collector, a Laval tube and a heat exchanger. The steam collector, the Laval tube and the heat exchanger are assembled in the shell, the steam collector is located above the Laval tube, the heat exchanger is located in vapor phase and liquid phase region surrounding the steam collector and the Laval tube, an inner cavity of the shell is communicated with a boiler sewage inlet tube, an evacuation tube is disposed at the top of the shell, and a bottom blow-off opening is arranged at the bottom of the shell. The sewage drainage energy-saving flash tank has the advantages that the sewage drainage energy-saving flash tank is simple and compact in structure, convenient in installation and operation and easy in popularization and use, can realizes energy conservation and water conservation effects, and the like.
Description
technical field [0001] The invention mainly relates to the field of waste heat utilization equipment, in particular to a waste water energy-saving expansion vessel suitable for waste heat boilers. Background technique [0002] In traditional boiler equipment, blowdown expansion vessels are often used. Common sewage expansion vessels include regular sewage expansion vessels and continuous sewage expansion vessels. Such as figure 1 and figure 2 As shown, it is a common sewage expansion vessel in the prior art, which includes a shell 1 and a first water vapor separator 14 and a second water vapor separator 15 located in the shell 1. The shell 1 is provided with a boiler sewage inlet The boiler sewage inlet pipe 11 and the inspection port 16 connected by water pipes, the top of the casing 1 is provided with an exhaust port 17 , and the bottom of the casing 1 is provided with a bottom sewage outlet 8 . [0003] Common sewage expansion vessels include regular sewage expansion...
