Abstract
The invention provides a seawater desalination process system. The system comprises a seawater supply device, a seawater discharge device, a condenser, a material water booster pump and an evaporator set, and is characterized in that the material water booster pump is arranged behind the condenser. The system is characterized by maintaining the inlet flow rate of the evaporator and the stability of a pressure head, contributing to equipment running and lowering the equipment cost.
Description
Technical field
The present invention relates to a kind of material water boosting pump and place condenser desalination process system afterwards.
Background technology
As shown in Figure 1, existing process stream water boosting pump is installed on the preceding process pipe of condenser, summer condition seawater temperature height, after entering condenser, need a large amount of seawater of preheating of discharging, cause energy wastage, influence the stable of evaporator inlet seawater flow and pressure.
Summary of the invention
The purpose of this invention is to provide a kind of desalination process system, comprise sea water supply device, seawater discharge equipment, condenser, material water boosting pump and evaporator bank, it is characterized in that material water boosting pump places after the condenser.Described evaporator bank comprises at least 2 vaporizers, for example 1 single-effect evaporator, 2 single-effect evaporators, 3 single-effect evaporators or the like.
Low-temperature multi-effect seawater desalination device is under the different load operating mode, the material water total flux and the pressure that advance vaporizer are constant value, the material water pump is placed on the material waterpipe behind the condenser, only lifting enters the material water of evaporator section to certain pressure head, before can avoiding pump to place condenser, because when seawater temperature changes, a large amount of drainings influence into the material discharge of vaporizer and stablizing of pressure head, simultaneously, former technology is for before placing condenser with material water boosting pump, need the discharging seawater is boosted together the waste pump horsepower.
The present invention keeps the stability of evaporator inlet flow and pressure head by material water boosting pump being placed after the condenser, is beneficial to the equipment operation, reduces equipment cost.
Description of drawings
Fig. 1 is the prior art seawater desalination system, and wherein material water boosting pump is arranged on before the condenser, and 1 is the m single-effect evaporator, and 2 is the n single-effect evaporator, and 3 are discharging seawater device, and 4 is condenser, and 5 is material water boosting pump, and 6 is the sea water supply device.
Fig. 2 is a seawater desalination system of the present invention, and wherein 11 is the m single-effect evaporator, and 12 is the n single-effect evaporator, and 13 is material water boosting pump, and 14 are discharging seawater device, and 15 is condenser, and 16 is the sea water supply device.
Embodiment
Seawater enters condenser 15 through sea water supply device 16, in condenser 15, finish preheating and degassing back separated into two parts, a part flows back to the sea by seawater discharge equipment 14 as refrigerated sea water, another part is transported to each single-effect evaporator (comprising m and n single-effect evaporator 11 and 12) as the material water of evaporative process by material water boosting pump 13.Heating steam enters in the heat-transfer pipe of the first single-effect evaporator (not shown) and condenses in pipe, seawater material water is evenly distributed on the overhead coil of vaporizer through spray equipment, form liquid film at tube surface, pipe flows downward with form of film in the action of gravity lower edge, material water is managed interior steam heating and is produced secondary steam, the secondary steam that generates enters behind vapour liquid separator in the pipe of next single-effect evaporator as heating steam, secondary steam is condensed into product water in next is imitated, the steam of last effect in condenser by the seawater condensation.Finished product water and salt solution enter down in the 1st effective evaporator by imitating, and partly flash distillation take place, and heat is taken back vaporizer, repeat spray, evaporation, condensation process in new effect group, and finished product water and strong brine are collected after finished product water pump discharger by imitating.
Claims (2)
1. a desalination process system comprises sea water supply device, seawater discharge equipment, condenser, material water boosting pump and evaporator bank, it is characterized in that, material water boosting pump places after the condenser.
2. according to the desalination process system of claim 1, it is characterized in that described evaporator bank comprises at least 2 vaporizers.
