Abstract
The invention discloses a tandem type sea water evaporator. A sea water heating part, an evaporation part and a condensation part are all separated by the sea water evaporator, so that the convenience is provided for modularization combination and utilization of different heat sources. According to the tandem type sea water evaporator disclosed by the invention, the tandem type sea water evaporator is divided into a plurality of evaporation units connected in series by baffles, hot sea water in the evaporation units can circulate, and hot air is fed into the hot sea water repeatedly for multiple times to take away water vapor. At last, fresh water is collected by a fresh water condensing device.
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 tandem sea water evaporator, this vaporizer is made up of some placed in-line evaporation elements, is to utilize warm air to take away the evaporation equipment of the water vapour in the hot sea water.
Two, background technology
The desalting seawater through multi-effect evaporation device is a kind of sea water evaporator to be combined, and carries out the device of sea water desaltination, and its main equipment is exactly a vaporizer.In vaporizer, heating medium is emitted heat makes seawater be heated evaporation, and the back of condensing generates fresh water.Present existing sea water evaporator comprises floodedevaporator, vertical tube falling-film evaporator and horizontal tube falling film evaporation device etc.Floodedevaporator is simple in structure, but heat transfer temperature difference is big, and heat transfer coefficient is little; The vertical tube falling-film evaporator has higher heat transfer coefficient, structurally need liquid be formed film uniformly at inner surface of tube, is beneficial to conduct heat; The horizontal tube falling film evaporation device belongs to baudelot evaporator, is applicable to the evaporation heat transfer under the little temperature difference, and heat transfer coefficient is high.
Also there is the method for utilizing the air saturation psychrometric difference to desalinize seawater at present existing a plurality of patents about sea water evaporator, but owing to reasons such as AT is lower, and moisture absorption is insufficient cause efficiency ratio lower.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 sea water evaporator, and this vaporizer device is made up of inlet mouth, air outlet, water-in, water outlet, baffle plate, breather line, exhaust transverse tube and insulation shell etc.The present invention separates evaporation component and seawater heater block, is convenient to utilize different thermal source heating.The present invention can regard as by some evaporation elements that are cascaded and constitutes; Each evaporation element is all by breather line UNICOM; Breather line one end is more than gauging line; One end is connected with the exhaust transverse tube, and the warm air that contains water vapour that comes of from last unitary hot sea water, overflowing will get into the hot sea water of next evaporation element from breather line and exhaust transverse tube.Through repeatedly evaporation, make that the water vapour content in the warm air reaches capacity.Saturated warm air gets into the condensing mechanism that the back is provided with from the air outlet, with the fresh water condensation.Utilize baffle plate to separate between the evaporation element, but there is the space bottom of baffle plate and insulation shell, to guarantee the mutual circulation of hot sea water in the evaporation element.The gauging line of hot sea water will be higher than the lower edge of baffle plate.The zygomorphy of exhaust transverse tube evenly has spilehole of the same size, and spilehole is positioned at below the gauging line of hot sea water, and warm air is evenly ejection from then on, seawater is rolled, accelerated evaporation.

Five, embodiment
Below in conjunction with accompanying drawing, embodiment of the present invention is described further.
Inlet mouth 1 external airheater and blower fan of the present invention, water-in 3 external seawater heating unit and water pumps, air outlet 2 external fresh water condensing workss, water outlet 4 external heat-exchanger rigs.Warm air gets into the evaporation of seawater unit from inlet mouth 1, evenly sprays from the spilehole 8 of exhaust transverse tube 7 both sides, makes the hot sea water evaporation of rolling.Contain the breather line 9 entering next evaporation element of the warm air of a large amount of water vapour from evaporation element top; Repeat to feed hot sea water, through behind a plurality of evaporation elements, the state that reaches capacity of the water vapour content in the warm air; 2 get into the fresh water condensing works from the air outlet, and fresh water condenses.Hot sea water gets into evaporation element from water-in 3, because the baffle plate of evaporation element 6 leaves the space with insulation shell 10 bottoms, hot sea water circulates at the evaporation element inner room.Seawater in sea water evaporator is after pervaporation reaches finite concentration, from water outlet 4 inflow heat exchangers, with the residual heat collection utilization.
