Embodiment approach 1

[0045] The first embodiment of the present invention provides a radiant cooling particle 1, see figure 1 As shown, the radiant refrigeration particles 1 are at least partly made of radiative refrigeration materials, suspended in the medium during use, and used to condense vapor in the medium.

[0046] Among them, the radiation cooling material is a material that can use infrared radiation to transfer heat from a heat source to a cold source in outer space through an atmospheric window of infrared radiation. Its refrigeration principle is similar to the natural refrigeration principle of the earth.

[0047] Those of ordinary skill in the art know that the energy of 200 petawatts that the earth absorbs from the sun every day is finally sent to the space near absolute zero in the form of radiation, so that its own temperature can be kept in balance within a certain range.

[0048]Radiation cooling materials can radiate energy in the form of infrared electromagnetic waves to achi...

Embodiment approach 2

[0055] The second embodiment of the present invention provides a radiation cooling particle 1 . The second embodiment is a further improvement of the first embodiment, the main improvement is that, in the second embodiment of the present invention, see figure 2 As shown, the radiation cooling particles 1 include:

[0056] Condensate liquid 11 is made of radiation refrigeration material;

[0057] The hydrophobic liquid 12 is connected with the condensate liquid 11 and is made of a liquid-repellent material;

[0058] The average density of the hydrophobic liquid 12 is greater than the average density of the condensate liquid 11 .

[0059] Among them, see figure 2 As shown, the shape of the condensate 11 is not particularly limited, and a spherical shape with the largest surface area is preferred. The shape of the hydrophobic liquid 12 can be a spherical shape which is relatively easy to process.

[0060] According to the kind of medium, the material of hydrophobic liquid ...

Embodiment approach 3

[0063] The third embodiment of the present invention provides a radiation cooling particle 1 . The third embodiment is a further improvement of the second embodiment, the main improvement is that, in the third embodiment of the present invention, see image 3 As shown, further, in this embodiment, the repellent liquid 12 is connected to the condensate liquid 11 through a thread 13 .

[0064] The condensing liquid 11 and the hydrophobic liquid 12 are connected by the wire 13 , which can make the exposed surface area of ​​the condensing liquid 11 and the hydrophobic liquid 12 larger than the direct connection of the two. The droplets formed on the condensate liquid 11 can flow to the hydrophobic liquid 12 along the thread 13, which is more conducive to the collection of the condensate liquid.

[0065] In addition, the flexible connection of the wires 13 can also better ensure that the relative position of the hydrophobic liquid 12 is always below the condensate liquid 11 , so t...

Abstract

The invention relates to the field of steam recycling, and discloses a radiation refrigeration particle and a steam condensation recycling device. At least part of the radiation refrigeration particleis made from a radiation refrigeration material. During use, the radiation refrigeration particle suspends in a medium, and is used for condensing steam in the medium. The steam condensation recycling device comprises a steam condensation cavity and the radiation refrigeration particle. The steam condensation cavity is full of the medium, and the radiation refrigeration particle suspends in the medium and is used for condensing the steam in the medium. According to the radiation refrigeration particle and the steam condensation recycling device, latent heat of condensation can be fast released to the external environment through radiation heat exchange without additional energy input or adsorbent, and the steam is efficiently condensed.

Description

technical field [0001] The invention relates to the field of steam recovery, in particular to a radiation refrigeration particle and steam condensation recovery device. Background technique [0002] Most of my country's new coal-fired units are built in the western coal-producing areas, and these areas are water-scarce areas. How to build large-scale coal power bases in water-scarce areas is a thorny issue for energy workers. After actively installing air-cooled condensers in newly-built units of coal-fired power plants in my country's water-scarce areas, the water consumption of the power plants has been greatly reduced. However, the steam emitted by a 600MW unit through the chimney is about 300t / h, and the annual water discharge is about 1.5 million tons. The water consumption is still very alarming. If the water in the chimney can be recovered and utilized as a resource, it will strongly support the construction of my country's coal power base, and it will be of great si...
