Description
Technical field
The utility model relates to vapor-liquid separating device field, particularly a kind of flash distillation plant.
Background technology
All need to use vaporising device when carrying out evaporation to solution and purifying, and solution usually can use flash distillation plant in whole evaporation technology process.Solution enters in flash tank, and after dilatation, pressure reduces, and solution seethes with excitement rapidly vaporization in flash tank, and carries out vehicle repair major separation.Flash tank can provide fluid to gasify rapidly and the space be separated, and its structure is simple, and energy consumption is low, good reliability, can make full use of the latent heat of liquid.Solution after flash distillation is discharged through taphole and is entered device for storing liquid.Pressure in flash tank is much smaller than external atmosphere pressure, and when adopting pumping drainage, higher vacuum makes the water of flash tank bottom not easily discharge, and existing solution adopts negative pressure of vacuum pump to draw water, and power is high, and power consumption is large, is unfavorable for energy-conserving and environment-protective.
Summary of the invention
The purpose of this utility model be to provide a kind of energy-conserving and environment-protective, reduce costs flash distillation plant.
The technical scheme of utility model is as follows: flash distillation plant, comprise flash tank, described flash tank side is provided with cooling water inlet, solution inlet port, the top of described flash tank is provided with steam (vapor) outlet, described steam (vapor) outlet is connected with vavuum pump, the opposite side of described flash tank is provided with the coolant outlet be communicated with cooling water inlet, the bottom of described flash tank is provided with taphole, described taphole connects the pump mouth of water pump by the first valve, the discharge outlet of described water pump connects two branch roads by the second valve, article one, branch road is by the 3rd valve, first one way stop peturn valve, it is inner that 4th valve connects described flash tank, another article branch road comprises the 5th valve, second one way stop peturn valve, 6th valve, one end of 6th valve is outlet end.
Steam-water separator is provided with between described steam (vapor) outlet and described vavuum pump.
The utility model is by adding two one way stop peturn valves in the front end of common water pump, during water pump operation, the first one way stop peturn valve closes, second one way stop peturn valve conducting, when water pump does not run, the conducting under the effect of solution gravity of the first one way stop peturn valve, the second one way stop peturn valve closes under the effect of the pressure, such can allowing before and after water pump is consistent with pressure in flash tank, the power of water pump can be reduced, increase the operational effect of water pump, also improve the service life of water pump to a certain extent.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, flash distillation plant of the present utility model, comprise flash tank 1, flash tank 1 side is provided with cooling water inlet 2, solution inlet port 3, and the top of flash tank 1 is located in cold import 2 of anhydrating, solution inlet port 3 is provided with below cooling water inlet 2, flash tank 1 bottom is provided with support 7, and the top of flash tank 1 is provided with steam (vapor) outlet 5, and steam (vapor) outlet 5 is connected with vavuum pump 6, vavuum pump 6, for extracting air, makes to keep vacuum in flash tank 1.The bottom of flash tank 1 is provided with heater 21, can accelerate the evaporation of solution.The opposite side of flash tank 1 is provided with coolant outlet 4, cooling water inlet 2 is communicated with by internal pipeline with coolant outlet 4, the bottom of flash tank 1 is provided with taphole 8, taphole 8 connects the pump mouth of water pump 9 by the first ball valve 10, the discharge outlet of water pump 9 connects two branch roads by the second ball valve 11, article one, three ball valve 12 of branch road by connecting successively, first one way stop peturn valve 13, it is inner that 4th ball valve 14 connects flash tank 1, another branch road comprises the 5th ball valve 15, second one way stop peturn valve 16, 6th ball valve 17, 6th ball valve 17 one end is outlet end 18, outlet end 18 connects device for storing liquid.Steam-water separator 19 and the 7th ball valve 20 is provided with between steam (vapor) outlet 5 and vavuum pump 6.The effect of steam-water separator 19 removes not by the moisture be suspended in steam that drain valve is drained.Steam moisture in a large number enters steam-water separator 19, and wherein with the centrifugal inclined motion that dips down; The moisture content carried secretly is separated because speed reduces; Separated liquid stream is discharged through drain valve, and the steam of dry cleansing is discharged from separator outlet.
Operation principle of the present utility model is: solution enters in flash tank 1 through solution inlet port 3, cooling water enters flash tank 1 by cooling water inlet 2, after solution enters flash tank 1, a temperature difference and pressure differential can be produced with the air in flash tank 1, thus solution is seethed with excitement immediately and produces a large amount of steam, the water vapour flashed off rises, and finally discharges from steam (vapor) outlet 13 and is separately used as him.Solution in flash tank 1 is due to the effusion of steam, and concentration increases, temperature reduces.Cooling water plays cooling and allows the effect of solution coagulates, solution after flash distillation is discharged from the taphole 8 bottom flash tank 1, taphole 8 connects the pump mouth of water pump 9, water pump 9 is common water pump, and the discharge outlet of water pump 9 connects two branch roads, when water pump 9 runs, the pressure of the relative tank body of pressure of water pump 9 delivery port is malleation, first one way stop peturn valve 13 closes, and the second one way stop peturn valve 16 conducting, solution gives off flash tank 1 by outlet end 18.When water pump 9 does not run, the solution be retained in the pipeline of outlet end 18 has pressure, second one way stop peturn valve 16 is in closure state, the conducting under the effect of solution gravity of first one way stop peturn valve 13, first one way stop peturn valve 13 and water pump 9, flash tank 1 is equivalent to formation loop, such pump mouth that can allow water pump 9, in discharge outlet and tank body, pressure is consistent, just vacuum pressure in tank body is not overcome when reruning, the lift of water pump 9 can be saved like this, reduce the power consumption of water pump 9, increase the operational effect of water pump 9, also improve the service life of water pump 9 to a certain extent.
The utility model, by the combination of specific valve and pipeline, makes water pump can not realize externally proper drainage by the impact of vacuum low-pressure in device.
