Abstract
The invention discloses a fresh water condenser for a seawater desalinization device. According to the condenser, cold seawater is used as a cooling medium, and a plurality of pipes which are formed by sleeving two pipes from inside to outside respectively are used as heat exchange parts, so that saturated moist air can be cooled; and fresh water can be obtained by saturated humidity differences of air at different temperatures.
Description
One, technical field
The present invention relates to sea water desaltination and technical field of heat exchangers, refer in particular to a kind of fresh water condenser, it is fresh water by interior pipe and the outward appearance heat exchanger components that constitutes that is nested together with the steam coagulation in the saturated moist air that this condensing surface utilizes several.
Two, background technology
Desalination technology is to go out salinity in the seawater and obtain the technological process of fresh water through sea water desalinization equipment, and method for desalting seawater mainly is divided into embrane method and distillation method.Embrane method desalination equipment used is simple to operate, invests lessly relatively, and start time is short, but must could work by electric power.Distillation method mainly comprises MSF, the low-temperature multi-effect and the three kinds of technology of distillation of calming the anger.Preceding two kinds of technology adopt steam to do thermal source, and the distillation of calming the anger then needs electric energy.Aforesaid method is not suitable for island, the desert that only has low-temperature heat source (sun power).
At present existing a plurality of patents of utilizing the air saturation psychrometric difference to desalinize seawater, but all be to focus on evaporation of seawater and in Air mixing, for how the moisture in the saturated moist air better being condensed, do not propose outstanding solution.Below list several existing related patent U.S. Patent No.:
Patent " is utilized the method for desalting seawater of air saturation psychrometric difference " (application number: 03144279.X) propose a kind of method for desalting seawater that utilizes the air saturation psychrometric difference; The seawater of heat temperature raising gets into and holds in the evaporation of seawater jar in heat collector; The gas blower exhausted air; Air is discharged through a plurality of exit airs place of connecting tube on gas distributor, and gas distributor is positioned at the bottom of evaporating pot maritime interior waters, air in adding hot sea water with the tiny bubble shape by rising above the lower direction; Air in the bubble is at the heated steam that absorbs simultaneously, and humidity increases.The air of moisture-saturated gets into the condensation comb that bends in the drainer by evaporating pot through connecting tube; Recirculated cooling water makes the air cooling-down of the moisture-saturated in the condensation comb; Steam can be separated out during the air cooling of saturated humidity, becomes the condensation fresh water of being discharged by the bottom.
(application number: 200410072793.4) propose a kind of atomized seawater desalination, in the evaporation of seawater chamber, put into seawater and heating, the temperature of heating is below boiling point for patent " atomized seawater desalination "; The seawater atomizing that elevates the temperature then; The atomizing seawater that temperature raises fully contacts with recirculated air, and the temperature rising humidity of recirculated air is strengthened, and absorbs large quantity of moisture; Again the recirculated air of high temperature, high humidity is introduced the seawater condensing chamber; Cooling and separate out water of condensation in condensing chamber, water of condensation is a fresh water, accomplishes the process of sea water desaltination.
Three, summary of the invention
The present invention proposes a kind of fresh water condenser, and this condensing surface is by the Mare Frigoris water inlet, Mare Frigoris water out, inlet mouth, air outlet, water outlet, gas-liquid separator, baffle plate, diluted gasket, steam dividing plate, base plate, interior pipe, outer tube, formations such as shell.Baffle plate and shell are separated into several parts that are connected with fresh water condenser, and Mare Frigoris water flows into from the Mare Frigoris water inlet, flow prolongation heat exchange stroke doing S shape about baffle plate down.There is the gap between the two in outer tube sleeve in interior tube outside.In pipe pass steam dividing plate and diluted gasket, with the space UNICOM that steam dividing plate and base plate surround, outer tube passes diluted gasket, the space UNICOM that surrounds with diluted gasket and steam dividing plate.Saturated moist air gets into condensing surface from inlet mouth, is sprayed onto on the outer tube wall through interior pipe, and catches a cold, and a part of water vapor condensation is become fresh water.Air-water mixture gets into the space that diluted gasket and steam dividing plate surround along outer tube, and gets into gas-liquid separator, carries out gas-liquid separation, and air flows out from the air outlet at last, and fresh water flows out from water outlet.Diluted gasket and outer tube material are the good material of heat conductivility, and interior pipe and steam separator material are the good material of heat-insulating property.Gap between diluted gasket and the steam dividing plate is bigger, and the gap between steam dividing plate and the base plate is less.Condenser casing is a lagging casing.
