Background technology
Currently, boiler controls boiler water quality in operation in order to the various soluble and insoluble impurities in pot water are discharged,
Boiler must carry out blowdown.Boiler blow-off is generally divided into continuous blowdown and periodical blowdown, the general direct emission of sewage of discharge, or
It is discharged after flash vessel pressure and temperature reducing.
Flash vessel be for by the blowdown decompression and expansion of boiler, sewerage expanded in expander be separated into indirect steam and
Spent hot water, indirect steam are drawn by special pipeline, and spent hot water is generally discharged into sewerage through blowdown cooling tank.
Traditional flash vessel only meets the demand of boiler blow-off, and a large amount of waste heat, waste water cause energy by direct emission
The waste in source.In actual operation, blowdown rate can reach the 1%~3% of boiler capacity to boiler, if it is possible to recycle this
The heat of effluent part will effectively improve the operational efficiency of boiler.
Invention content
In order to solve the problems, such as that boiler is periodically provided with continuous sewage effluent heat recovery, the utility model
Absorption flash vessel.The flash vessel solves the skill of boiler blowdown water and waste heat recovery by the way that heat dump is subsequently arranged in flash vessel
Art problem.
Scheme is used by the utility model solves technical problem：
Boiler blow-off water lines are connected in flash vessel top side, lower part is connected with blowoff line, has in flash vessel

Road, cold water pipeline are placed in tank top.
Good effect utilizes flash vessel itself internal pressure, gas since the utility model is combined using flash vessel with heat dump
Body flows kinetic energy, realizes that vapour, water separation collect again into heat dump, heat recycles completely in sewerage.Make flash vessel cooling, subtract
While pressure, the thermal energy in boiler blowdown water can be recycled completely, reduces the waste of water resource.Has the advantages that energy conservation and environmental protection.
Suitable for being used as absorption flash vessel.

There is water layer and gas-bearing formation in flash vessel, be connected with steam pipework 5 in flash vessel upper end and gas-bearing formation, heat is connected in flash vessel water layer
Water lines 8, steam pipework and hot water line, which converge, to be connected to by hot water line with heat dump 3, be equipped on hot water line valve 10,
Pressure gauge 11 and thermometer 12 are equipped with heat exchanger plate 3.1 in heat dump, and left side is heat supply end, and right side is heat-exchange end, is being absorbed heat
Device heat-exchange end top is connected with boiler replenishing water outlet pipeline 6, and boiler replenishing water inlet pipeline is connected in heat dump heat-exchange end lower part
7, it is connected with cold water pipeline 13 in heat supply end lower part, cold water pipeline is placed in 4 top of tank.
Heat exchanger plate is equipped in the heat dump, heat exchanger plate both sides are respectively equipped with heat supply end and heat-exchange end.
The course of work：
Boiler is periodically and continuous blowdown water enters the expansion with certain internal pressure and equipped with pressure gauge through boiler blow-off water lines
Container periodically discharges after the insoluble impurities in boiler blowdown water deposits in flash vessel bottom through blowoff line；
Sewerage realizes vapour, water separation in flash vessel after cooling decompression, the steam of separation is via steam pipework and separation
Hot water pooled together via valve and hot water line, on hot water line be equipped with pressure gauge and thermometer, hot water line with
Heat dump heat supply end communicates, and the water in heat dump after heat release cooling enters tank through cold water pipeline；
Boiler replenishing water enters heat dump by the control of pressure gauge, thermometer and valve through boiler replenishing water inlet pipeline and exchanges heat
End, the water in heat dump heat-exchange end after heat absorption heating are delivered to boiler replenishing water outlet pipeline through valve control.
