Evaporator inner cavity lower surface is horizontal, and upper surface is obliquely installed.
A kind of compact type desalination plant provided by the invention, evaporator, condenser and the close of cooler bin are matched It closes and uses, the present invention is made to be not necessarily to large-scale refrigeration equipment, it is small in size, it can be independently operated, and easily operated;Heating plate is set It sets, concentrated seawater on hot plate flow through to form a thin layer of liquid film by surface, and vapor is generated under the heat effect of heating plate and is filled It is full of in evaporator, keeps concentrated seawater evaporation rate fast;The setting of blower, the air for blowing out vapor with blower are mixed into damp and hot Steam is humidified to form wet-hot steam and accelerate the speed that wet-hot steam enters condenser to vapor, and sea water desalination speed is fast;Add Hot plate tilt adjustable, making liquid film, the residence time is variable on hot plate, therefore adjustable concentrated seawater evaporation rate;Plate is set Set, realize blower air intake vent size can LINEAR CONTINUOUS adjust, influence of the different wind speed to whole system fresh water yield can be studied; The inner cavity lower surface of evaporator is horizontal, and the inclined setting in upper surface is flowed inside evaporator from bottom to top convenient for wind, accelerates light The water speed of response;Hot sea water exports the setting that directly connect with concentrated seawater case, makes hot sea water in evaporator will not be directly as Waste water discharge, but become warm seawater to the cold seawater preheating heating in concentrated seawater case using the marine thermal energy of heat, make evaporator The seawater of subsequent concentration is warm seawater, reduces the energy consumption and seawater concentration time of heating plate;Spiral coil cooling tube outlet with it is dense The setting of sea water tank connection, equally realizes energy regenerating, and the warm seawater of spiral coil cooling tube outlet is also given cold in concentrated seawater case Seawater preheating heating, is further reduced the energy consumption and seawater concentration time of heating plate.The present invention generates light for concentrated seawater desalination Water can ensure that coastal water-deficient region Drinking Water for Residents supplies.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention;
Fig. 2 is the structural schematic diagram of evaporator in the present invention.
Specific embodiment
The present invention will be further explained with reference to the accompanying drawing.
As shown in Fig. 1 ~ Fig. 2, a kind of compact type desalination plant, mainly by blower 1, evaporator 2, heating plate 3, Condenser 4, spiral coil cooling tube 5, fresh water collecting case 6, cooler bin 7, concentrated seawater case 8, cooling pump 9, concentrated seawater pump 10 and heat insulation layer 11 compositions.Wherein: 1 air intake vent size of blower can LINEAR CONTINUOUS adjust, different wind speed can be studied to whole system fresh water yield It influences, 1 air outlet of blower is connect with the wind entrance of evaporator 2;Evaporator 2 is made of resistant material, for example, ceramics, prevent by Seawater corrosion, evaporator 2 include wind entrance, wet-hot steam outlet, Mare Frigoris water inlet and hot sea water outlet, apoplexy entrance and wind Machine 1 connects, and wet-hot steam outlet is connect with condenser 4, and Mare Frigoris water inlet is connect by concentrated seawater pump 10 with concentrated seawater case 8, heat Seawer outlet is directly connect with concentrated seawater case 8;The inclination of heating plate 3 is placed in evaporator 2, and heating plate angle can be adjusted as needed Section, concentrated seawater, which flows through in 3 upper surface of heating plate and generates vapor, to be filled in evaporator 2, the sky that vapor and blower 1 are blown out Gas is mixed into wet-hot steam;Spiral coil cooling tube 5 is used to the cooling damp and hot air-water mixture for exporting out from 2 wet-hot steam of evaporator And obtain cooling down light water and air, 5 import of spiral coil cooling tube is connect by cooling pump 9 with cooler bin 7, and spiral coil cooling tube 5 exports It is connect with concentrated seawater case 8;Fresh water collecting case 6 is connected to immediately below condenser 4, and wet-hot steam is after spiral coil cooling tube 5 is cooling Fresh water droplet is generated, fresh water droplet finally flows into fresh water collecting case 6 in the convergence of 4 bottom of condenser;7 cooling water of cooler bin Outlet is connect with 5 import of spiral coil cooling tube, reduces temperature in spiral coil cooling tube, improves cooling effect;Concentrated seawater case 8 is placed in cooling 7 top of case, in order to prevent heat exchange between concentrated seawater case and cooler bin, is separated with heat insulation layer 11 therebetween.
The evaporator 2 is " mouth " font perpendicular to wind inlet face section, and 2 lower surface of evaporator is horizontal, upper surface inclination Certain angle flows from bottom to top for wind and creates hardware condition.
Wind entrance is parallel with wet-hot steam outlet.
8 intake-outlet of concentrated seawater case and evaporator 2 form closed circuit.
3 lower end of heating plate is fixed in evaporator 2 by revolute pair inclination, therefore 3 angle of heating plate can be as needed It adjusts.
5 import of spiral coil cooling tube is connect by cooling pump 9 with cooler bin 7, and outlet is connect with concentrated seawater case 8, is prevented snakelike Coolant overheating influences cooling effect in cooling tube.
The cooler bin 7, which is connected by pump with cooling tower, further decreases coolant temperature, improves cooling effect.
The operating process of sea water desalination of the present invention is as follows:
Evaporation stage: the Mare Frigoris water in concentrated seawater case 8 enters evaporator 2 by concentrated seawater pump 10, and concentrated seawater is from top to bottom It is flowed through from 3 upper surface of heating plate and forms a thin layer of liquid film in 3 upper surface of heating plate, heating plate 3 generates after heating concentrated seawater Vapor, while the air that blower 1 and 2 junction of evaporator are flowed from bottom to top is mixed to form wet-hot steam with vapor.
Condensation phase: wet-hot steam meets with snakelike cold after the interface of evaporator 2 and condenser 4 enters condenser 4 But the condensation of pipe 5 forms fresh water droplet, and fresh water droplet flows into fresh water collecting case 6 after 4 bottom of condenser is converged.
The cooling of coolant and energy regenerating: constantly injecting refrigerated sea water in cooler bin 7, cooling pump 9 is by refrigerated sea water pressure Enter in spiral coil cooling tube 5, reduces cooling water temperature in spiral coil cooling tube 5;From the cooling water temperature of the outlet of spiral coil cooling tube 5 outflow The cooling water in exit is connect by significantly larger than 5 inlet temperature of spiral coil cooling tube with concentrated seawater case, realizes energy regenerating.
The present invention generates fresh water for concentrated seawater desalination, can ensure that coastal water-deficient region Drinking Water for Residents supplies.
The above is only a preferred embodiment of the present invention, it should be pointed out that: for the ordinary skill people of the art For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered It is considered as protection scope of the present invention.
