Said invention is characterized by that the exterior of storage tank of distilled liquid is equipped with heat-insulating material to make it form a heat-insulating system relative to exterior, and an air compressor and an evaporative condenser are set in the liquid of storage tank and a heating device is placed under the storage tank, and a steam space is retained in the upper portion of the storage tank, and the input pipe inlet of the air compressor is positioned in the steam space, and the output pipe of the air compressor is communicated with the condenser inlet.
Description
The present invention relates to a kind of distilling apparatus, particularly a kind of device that utilizes the used heat in the still-process to distill.Comprise heater in the device of the present invention, the condensation heat exchange device, the pipeline of connection condensing unit and condensate liquid storage tank, liquid to be distilled is carried the pipeline of liquid, and is arranged at the by-pass valve control on each pipeline.
Traditional distilling apparatus all has a vaporising device and a condensing unit, by vaporising device distilland is heated to boiling point and is evaporated to steam, again with condensing unit with the vapor collection condensation.This traditional distilling apparatus energy consumption is too high, and it is more to consume condensing agent.With water is example, once the gram 20 ℃ water a normal atmosphere depress evaporate fully required heat be 619 the card, as also need to consume 10 times condensed water with water-cooled.A kind of heat-pump-type distillation machine is disclosed for addressing this problem Chinese utility model patent 96210919.3, it is to have adopted heat pump that condensed water institute liberated heat is reclaimed to heat to overcome the deficiencies in the prior art, but because of the efficient of heat pump own lower, estimate that its energy consumption is still bigger, also impracticable.
The purpose of this invention is to provide a kind of device that the prior art deficiency can realize the liquid distillation with minimum energy consumption that overcomes.
Device of the present invention adopts following measure to realize: the outside of containing the storage tank that is evaporated liquid in is provided with heat-insulation material, and making the present invention is an adiabatic system mutually to external world.A gas compressing apparatus is set in the inside of liquid case, vaporising device and have the heat-exchange device of condensing unit, and described compression set, condensing unit all are in and are evaporated among the liquid, below being evaporated the liquid tank liquid level, be provided with heater near the liquid level place, and in vapor space of the top of liquid case reservation, the input mouth of pipe of described gas compressing apparatus is arranged in the vapor space, the efferent duct of gas compressing apparatus and the pipeline conducting of the inlet of condensing unit that is evaporated liquid tank liquid level top.When working, the present invention at first utilize heater to heat at the liquid upper box part, make partially liq vaporization (annotating: when the present invention starts working, do not need to make liquid boiling), by gas compressing apparatus the steam of liquid level top is sucked and compresses through input pipe, its operating pressure reaches 0.16～0.36MPa for well, compressed liquid vapour enters in the condensing unit, simultaneously because the temperature of compressed effect liquid vapour raises (vapor (steam) temperature is about 120～140 ℃), high-temperature fluid steam carries out heat exchange by the liquid to be distilled in heat exchanger and the liquid case in condensing unit, steam condensation on the condensing unit wall, liquid through condensation flows in the condensate liquid storage tank by pipeline, the heat of steam is then again in the liquid to be distilled in the retrieval system, fluid temperature is raise evaporate, realize the purpose of liquid distillation thus.Can cut off the heat supply of heater after its inside produced after work of the present invention a period of time heat and dispersed heat reach balance, the heat that only utilizes compression set and produced is kept system's operate as normal.
The power source of gas compressing apparatus of the present invention preferably adopts motor, and motor also places among the liquid that is evaporated liquid tank, and the heat that is produced during motor work also can be retained in the working environment fully like this.
Second heat exchanger that heat-exchange device of the present invention preferably adopts first heat exchanger that plate heat exchange unit of mutual UNICOM constitutes and tubing heat exchanger to constitute is formed, establish condensing unit in first heat exchanger wherein, adopt second heat exchanger with the entrained heat of further minimizing condensed fluid, can further improve the efficient of device like this.
In the present invention, gas compressing apparatus, vaporising device and condensing unit be all along vertical layout of liquid case, make liquid along storage tank bigger thermograde vertically arranged, this helps improving the efficient of device.
The cross section, top that is evaporated liquid tank of the present invention is less than lower section, and can there be best effect in the cross section, top of condensing unit like this greater than cross section, its underpart.
The present invention mainly is the heat of transformation, compression set heating and the electric motor overheating of the recycling steam thermal source as distillation in its work, and has distillation efficiency height, advantage of low energy consumption owing to be an adiabatic system.Can obtain the distillation water yield greater than 4 liters according to the test every kilowatt hour of data the present invention of surveying, be several times as much as prior art.The present invention can be used for desalinization, also can be used for other liquid purifying, or be used for the liquid after polluting is handled, and the drying that can also adopt the present invention to carry out some product is handled.
Accompanying drawing provides the generalized section of one embodiment of the present of invention, below in conjunction with description of drawings.
Make an airtight housing (15) with heat-insulating material in the present embodiment, in housing (15), be the liquid that is evaporated, motor (1) is set in the liquid in housing, gas compressor (2), heat-exchangers of the plate type (3), trumpet cooler (4), wherein the inwall of heat-exchangers of the plate type (3) is the condensation collecting board, its outer fin (not representing fin among the figure) that is provided with, the opening of the input pipe (5) of gas compressor (2) is positioned at the liquid level top, the efferent duct of gas compressor with as heat-exchangers of the plate type (3) conducting of first heat exchanger, the output of heat-exchangers of the plate type (3) with as tubing heat exchanger (4) conducting of second heat exchanger, the efferent duct of tubing heat exchanger with another pipeline be arranged at housing condensate liquid storage tank (11) outward and be communicated with.Outside housing, be provided with valve (7) by fluid level controller (8) control, the feed tube of valve (7) and pending fluid connection, drain pipe and housing (15) internal communication, the liquid level place is provided with liquid level sensor (9) and following liquid level sensor (10) respectively in housing (15), below liquid level, be provided with electric heater (6), be provided with gas pressure limiting valve (20) in the space above liquid level, to prevent the too high destruction that causes device of air pressure because of the liquid level top vapor space, below housing (15), be provided with a blowoff valve (13), on condensate liquid storage tank (11), be provided with tapping valve (12).In plate-type condenser (3), also be provided with barometer (16) in the present embodiment, in housing, also be provided with liquid temperature sensing element (17) below the liquid level, on condensate liquid storage tank (11), also be provided with another liquid level sensor (19) and controller (18).
