Abstract
The invention discloses a vacuum flashing heat exchanger. The vacuum flashing heat exchanger is characterized by comprising a hot water container (2), a flasher (1), a vacuum pump (5) and a flashing heat exchange unit (8); the hot water container (2) is used for accumulating thermal fluid medium; the inlet end of the flasher (1) is connected to the hot water container through a hot water pump (3); the vacuum pump (5) is used for evacuating the flasher and is connected to the flasher; the flashing heat exchange unit (8) is connected to a steam outlet of the flasher through a pipe. The vacuum flashing heat exchanger has the advantages that clean water vapor is made from low-temperature slag washing water or geothermal water, the slag washing water or the geothermal water with the waste heat failing to be recycled due to presence of impurities is fully utilized, energy is saved, and better economic benefit is brought.
Description
Technical field
The present invention relates to a kind of vacuum environment that utilizes makes water at low temperature form the vacuum flashing heat-exchanger rig of steam.
Background technology
At present, the more difficult direct recycling of heat energy in blast furnace slag quenching water and GEOTHERMAL WATER.Main cause there is a large amount of impurity in washing slag water and GEOTHERMAL WATER, and washing slag water and GEOTHERMAL WATER water temperature are not enough to directly form steam, if use traditional waste heat recovery to make washing slag water directly contact with heat exchanger with GEOTHERMAL WATER, Exchanger Tubes is easily made to produce dirt thus make heat exchanger failure.
Summary of the invention
Object of the present invention is exactly to solve the problem, a kind of vacuum flashing heat-exchanger rig is provided, this vacuum flashing heat-exchanger rig can make the washing slag water of low temperature and GEOTHERMAL WATER utilize vacuum evaporation for water vapour, forms clean steam, carries out heat exchange with the heat exchanger of low boiling point working medium.Thus realize washing slag water and GEOTHERMAL WATER carries out waste heat recovery.
To achieve these goals, the present invention adopts following technical scheme:
Vacuum flashing heat-exchanger rig, is characterized in that, has:
For accumulating the hot water tank (2) of hot fluid medium;
Flash vessel (1), its arrival end is connected to hot water tank by heat-exchanger pump (3);
For the vavuum pump (5) vacuumized flash vessel, it is connected to flash vessel;
Flash Type heat exchanger (8), it is arranged in the steam (vapor) outlet of flash vessel by pipeline.
Further, this vacuum flashing heat-exchanger rig, also comprises:
For accumulating the water-storing device (7) of cold water medium, the described condensation-water drain of Flash Type heat exchanger and the condensation-water drain of flash vessel are all arranged in water-storing device by pipeline.
In this case, regulate pressure by vavuum pump, make pressure in flash vessel body lower than atmospheric pressure, make to evaporate formation steam by the hot water section in heat-exchanger pump suction flash vessel body.
In this case, washing slag water etc. evaporate under vacuum, form clean steam.Low Temperature Steam condensation release heat, worker quality liquid evaporation is formed working substance steam.
The present invention has following beneficial effect: the washing slag water of low temperature or GEOTHERMAL WATER can be made to form clean steam, the washing slag water and GEOTHERMAL WATER that cannot recycle waste heat because there is impurity are fully used, while economize energy, bring preferably economic benefit.
Accompanying drawing explanation
Fig. 1 is vacuum flashing heat-exchanger rig structural representation.
Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
As shown in Figure 1, vacuum flashing heat-exchanger rig, it has: for accumulating the hot water tank 2 of hot fluid medium, such as cistern, it is used for accumulating such as washing slag water and GEOTHERMAL WATER; Flash vessel 1, its arrival end is connected to hot water tank by heat-exchanger pump 3, and the hot-water line 4 being delivered to flash vessel at the hot fluid of hot water tank is provided with by-pass valve control; For the vavuum pump 5 vacuumized flash vessel, it is connected to flash vessel; Flash Type heat exchanger 8, it is arranged in the steam (vapor) outlet of flash vessel by pipeline, and Flash Type heat exchanger has the entrance 80 of worker quality liquid and working substance steam outlet 81 and condensation-water drain 82.The steam that flash vessel produces makes the worker quality liquid in Flash Type heat exchanger evaporate and forms working substance steam output, and the condensed water of generation then gets back to the cold water collecting device of Operation system setting by condensate pipe.
This vacuum flashing heat-exchanger rig, also comprises: for accumulating the water-storing device 7 of cold water medium, the described condensation-water drain of Flash Type heat exchanger and the condensation-water drain of flash vessel are all arranged in water-storing device by pipeline.The condensed water that flash vessel produces directly leads to water-storing device by downpipe 6.
Flasher base is connected with flushing cinder or underground heat hot-tub pipeline.By heat-exchanger pump in hot water suction flash vessel equipment, and by vavuum pump, flasher is vacuumized, when the pressure in flasher reduces, the boiling point of steam reduces, make to form steam from the hot water in hot water tank, reach the effect that flash vessel produces clean steam.
The foregoing is only the preferred embodiment of the present invention, protection scope of the present invention is not limited in above-mentioned embodiment, and every technical scheme belonging to the principle of the invention all belongs to protection scope of the present invention.For a person skilled in the art, the some improvement carried out under the prerequisite not departing from principle of the present invention, these improvement also should be considered as protection scope of the present invention.
