Detailed Description
The present invention will be described in further detail with reference to the following examples:
the utility model provides a low pressure flash distillation heat sink, as shown in figure 1, it includes overhead tank 8, overhead tank 8's upper portion is connected with feed liquor pipe 5, and the bottom is connected with drain pipe 7. The end of feed liquor pipe 5 is equipped with shower nozzle 3, shower nozzle 3 sets up in overhead tank 8, and the pressure value that the pressure in the overhead tank 8 was set for the system, the top of overhead tank 8 is equipped with the manometer 1 with the inside intercommunication of overhead tank 8, and manometer 1's setting can the pressure size of visual display overhead tank 8, and when pressure was higher than the setting value, vacuum circulation pump 12 opened and taken away the partial air in the overhead tank 8 and made the pressure reduction in the overhead tank 8 reach the setting value, makes things convenient for the low pressure boiling vaporization of liquid.
The boiling point of the substance is increased along with the increase of the pressure, and the lower the pressure, the lower the boiling point, so that the boiling point of the high-temperature and high-pressure liquid is reduced after the pressure is reduced, and at the moment, the temperature of the liquid is higher than the boiling point under the pressure, and the liquid reaches instant boiling vaporization. After the high-temperature and high-pressure liquid in the liquid inlet pipe 5 is sent into the pressure tank 8 through the circulating pump 4 on the liquid inlet pipe 5, because the pressure in the pressure tank 8 reaches the boiling point of the high-temperature liquid, at the moment, the high-temperature and high-pressure liquid enters the pressure tank 8 through the spray head 3 and is instantly atomized at the spray head 3, the surface area of liquid vaporization is increased, the liquid is rapidly boiled and vaporized in a low-pressure state, two-phase separation is realized, and then the heat is smoothly taken out through the steam pipeline 13 communicated with the atmosphere at the top of the pressure tank 8.
The steam pipeline 13 is provided with a vacuum circulating pump 12, on one hand, the arrangement of the vacuum circulating pump 12 can smoothly take away the latent heat of liquid vaporization, on the other hand, air in the pressure tank 8 can be pumped away to reduce the pressure in the pressure tank 8 to a set pressure value, and conditions are created for low-pressure boiling vaporization of the liquid.
The pressure tank 8 is also internally provided with a filler 6 and a baffle 2, and the filler is PVC commonly known as flame-retardant polyvinyl chloride. The filler 6 is arranged below the spray head 3, the baffle 2 is arranged above the spray head 3, when liquid sprayed by the spray head 3 is instantly boiled and vaporized, most of steam is upwards discharged through the baffle 2 under the action of the vacuum circulating pump 12 through the steam pipeline 13 and collected for recycling, and the energy utilization rate is greatly improved. When steam passes through the baffle 2, water vapor passes through smoothly, and moisture is retained, so that the vacuum circulating pump 12 can prevent water from being pumped out of the pressure tank 8 under the negative pressure environment of the pressure tank 8. A part of steam sprayed by the spray head 3 falls onto the filler 6 under the action of gravity, and the arrangement of the filler 6 increases the surface area of heat and moisture exchange, thereby being beneficial to releasing more heat. The water vapor sprayed from the nozzle 3 partially enters the water in the pressure tank 8 through the filler 6, so that the temperature of the water is increased.
As shown in fig. 1, a water return pipe 14 connected to the water reservoir 10 is provided on the steam pipe 13, and part of the steam in the steam pipe 13 is discharged to the outside, and part of the steam is condensed in the steam pipe 13 into water and flows back to the water reservoir 10 through the water return pipe 14 connected to the steam pipe 13. The arrangement of the water return pipe 14 can lead the steam condensate water in the steam pipeline 13 into the water storage tank 10, thereby not only avoiding the retention of the moisture in the steam pipeline 13, but also achieving the effects of moisture circulation and energy conservation.
One side of overhead tank 8 is equipped with the water gauge 15 that shows water level height in the overhead tank 8, when the water gauge 11 of overhead tank 15 one side shows that the water yield is not enough, opens the moisturizing pump 9 of one side and takes out the water in the cistern 10 and carry out the moisturizing in the overhead tank 8, makes the water level invariable in the overhead tank 8, through the moisturizing device 12 of opposite side when the water yield is not enough in cistern 13 in to the cistern 10 in the replenishment.
In the implementation process, high-temperature and high-pressure liquid enters the pressure tank 8 with set pressure through the spray head 3 of the liquid inlet pipe 5, the pressure is reduced, the high-temperature liquid is instantly boiled and vaporized, namely, the high-temperature and high-pressure saturated liquid enters the pressure tank 8 with low pressure, and the high-temperature and high-pressure saturated liquid is boiled and vaporized due to sudden reduction of the pressure, so that the saturated liquid with the temperature is changed into saturated steam under the pressure, namely, the low-pressure flash evaporation technology.
Finally, it should be noted that: the above examples are given for the sake of clarity and are not intended to be exclusive, nor are they intended to limit the scope of the invention. It will be apparent to those skilled in the art that many more modifications and variations than mentioned above are possible in light of the above teaching, and it is not intended to be exhaustive or to limit the invention to the precise form disclosed.
