Background technology
The desalination technology that can drop into the commercialization use at present mainly contains two classes, and a class is a distillation method, and a class is an embrane method.The distillation sea water desalting technology comprises multistage flash evaporation, low temperature multiple-effect distillation, three kinds of methods of pressure steam distillation.The characteristics of low temperature multiple-effect distillation are: the pre-treatment to raw material seawater is less demanding, and the process circulation power consumes little, the fresh water water quality height of production.This technology is one of technology of the tool development prospect of sea water desaltination.In this technology, the steam jet vacuum system, instant heating compression pump, steam ejection vacuum pump unit, startup squirt pump are indispensable vacuum acquiring systems.The steam ejection vacuum pump unit is set up vaporizer and is kept vacuum, could realize evaporation under the seawater low temperature, and the thermo compression pump is recycled low temperature secondary vapour.
The utility model content
Purpose of design: avoid the weak point in the background technology, design a kind of steam jet vacuum system that low-temperature multiple-effect seawater desalination is handled that is used for.
Design: in order to realize above-mentioned purpose of design.The utility model is in system design, the low-temperature multiple-effect seawater desalination vacuum system adopts thermo compression pump, steam jet pumping set, starts squirt pump three combination, be main technical characteristics of the present utility model, the purpose of doing like this is: start squirt pump and can set up the interior initial vacuum of vapo(u)rization system fast; The steam ejection vacuum pump unit is kept the pairing vacuum requirement of low-temperature distillation; (minimum temperature) imitated at the end with the thermo compression pump or middle a certain effect secondary vapour is recycled, and compression heats up in back input first (top temperature) generating tube.Realize the recycling of secondary vapour, as the thermal source of the first effect evaporator room, the secondary vapour heat of recovery has improved the total efficiency of system again.
Technical scheme: low-temperature multiple-effect seawater desalination water treatment vapo(u)r blasting vacuum system, one-level injector and first-stage condenser polyphone, two-stage injection device and secondary condenser polyphone, first-stage condenser and secondary condenser polyphone, the first-stage condenser outlet is communicated with the import of two-stage injection device, one, two-stage injection device import connection is communicated with the desuperheater outlet, the one-level injector is communicated with precondenser, precondenser import one tunnel be communicated with the condenser outlet by pipeline and valve, one the tunnel is communicated with the outlet of condensate cooler, and secondary condenser exports one the tunnel and is communicated with first-stage condenser, one the tunnel is communicated with a certain effect condenser.
The utility model is compared with background technology, the one, start squirt pump, can set up the initial vacuum of vapo(u)rization system fast, not only rate of air sucked in required is big, and the time is fast, has guaranteed that three (two) grades of steam ejection vacuum pump units can satisfy the vacuum requirement of system under the various low temperature, the working steam of the effective condensation prime of condenser injector and taken out and can coagulate steam in the middle of it, reach the load that reduces back level injector, reach the purpose that cuts down the consumption of energy; The 2nd, the thermo compression pumping action is that secondary steam is recycled, and has improved the total efficiency of system, can satisfy the job requirement of different water outlet loads with adjustable thermo compression pump.

Embodiment
Embodiment 1: with reference to attached Fig. 1 and 2.Low-temperature multiple-effect seawater desalination water treatment vapo(u)r blasting vacuum system, one-level injector and first-stage condenser polyphone, two-stage injection device and secondary condenser polyphone, first-stage condenser and secondary condenser polyphone, the first-stage condenser outlet is communicated with the import of two-stage injection device, one, two-stage injection device import connection is communicated with the desuperheater outlet, the one-level injector is communicated with precondenser, precondenser import one tunnel be communicated with the condenser outlet by pipeline and valve, one the tunnel is communicated with the outlet of condensate cooler, and secondary condenser exports one the tunnel and is communicated with first-stage condenser, one the tunnel is communicated with a certain effect condenser.The import of described precondenser is communicated with injector.Pipeline before precondenser and between the condenser is communicated with, and relief outlet is provided with sound damper.
As shown in the figure, steam compressor after the compressed intensification is imported the suction of quadruple effect secondary vapour in the 1st effective evaporator.The precondenser of three (two) grades of vapo(u)r blasting pumping sets links to each other with a condenser and the vaporizer of imitating that imitate at the end, and precondenser adopts the direct-cooled type of atomizing spray.One-level injector suction opening links to each other by the air outlet of pipeline and precondenser, one-level injector venting port is connected to the inlet mouth of first condenser, the first condenser air outlet links to each other with two-stage injection device suction opening, two-stage injection device venting port is connected to the inlet mouth of second condenser, the direct emptying of second condenser.(being suitable for two-stage injection pumping set pattern).The secondary condenser air outlet links to each other with three grades of injector suction openinies, and three grades of injector venting ports are established noise reduction condenser emptying (being suitable for three grades of squirt pump unit patterns).Start injector and be connected on the pipeline between the preceding and condenser of squirt pump unit (or precondenser), relief outlet is provided with sound damper.
During work, open earlier and start injector, when the system vacuum degree reaches set(ting)value, close the startup injector, open three (two) grades of steam injectors, system is reached and remain on the vacuum tightness of processing requirement.The non-condensable gases that contains in the steam is imitated the back extraction from the end, the non-condensable gases that enters system with seawater is drawn out of in an effect, thereby guarantee that imitating a vacuum tightness of imitating from the end reduces step by step, make evaporation temperature of seawater imitate the end and imitate reduction step by step from one, produce siphon simultaneously seawater is got by brinepump after an effect flows to the end effect automatically, to reach the purpose of save energy.Steam compressor then is that the secondary vapour that quadruple effect produces is extracted out, gets back to one and imitate and add hot sea water usefulness after supercharging heats up, and makes the heat energy can recycle.Therefore reduced energy consumption.
What need understand is: though the foregoing description is to the mentality of designing of the present utility model detailed description of contrasting; but these descriptions; just the character property of the utility model mentality of designing is described; rather than to the restriction of the utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the present utility model.
