Description
Technical field
The utility model relates to a kind of sea water desalinating plant, especially relates to the device that uses reverse osmosis method to carry out sea water desaltination.
Technical background
Method for desalting seawater has distillation method, embrane method (electrodialysis, reverse osmosis, film evaporation etc.), crystallization process, solvent extration and ion exchange method etc. multiple.Wherein reverse osmosis method is a kind of method that has development potentiality.Require injection temperature to be not less than 15 ℃ to improve desalination by reverse osmosis efficient in the reverse osmosis method desalination process, because winter, seawater temperature was lower, seawater temperature does not reach requirement in certain areas, must take seawater heating measure in the technological process.Heating means mainly contain fire coal, combustion gas, oil-firing boiler heating and Electric heating at present, and energy consumption is higher, and the boiler smoke discharging has certain influence to environment.
Summary of the invention
The purpose of this utility model provides a kind of save energy, uses the reverse osmosis method sea water desalinating plant of the band heat recuperation of environmental protection.
Technical solution of the present utility model is: the reverse osmosis method sea water desalinating plant of band heat recuperation, the reverse osmosis membrane that comprises water pump, the well heater that order is connected and be provided with concentrated seawater outlet and water outlet, wherein, between water pump and well heater, be provided with interchanger, side in Tube Sheet of Heat Exchanger side or the shell-side is connected with the temperature end of heat pump, opposite side is connected with seawater, and the low-temperature end of heat pump links to each other with the water outlet of reverse osmosis membrane.
In the reverse osmosis method sea water desalinating plant, the seawater that enters in the reverse osmosis membrane need heat the raising temperature, and the fresh water temperature of producing in the reverse osmosis membrane is higher, heat pump can be from the fresh water that produces heat-obtaining and it is used for preheating calorifier inlets seawater, so just utilized the waste heat of system's discharging fully, reduce the required energy consumption of well heater, reduced the required energy consumption of desalting equipment, improve the efficient of desalting equipment.
As a kind of prioritization scheme, be serial or parallel connection between described interchanger and the described well heater, can heat pump be set flexibly according to different desalting equipments like this, effectively reduce the energy consumption of desalting equipment, and adapt to different occasions.
The utility model has the advantages that: simple in structure, easy to use, effectively reduced the heating energy consumption and the expense of desalting equipment, use simultaneously and go back safety and environmental protection.
