Detailed Description

Embodiments of the present invention will now be further described with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

Example 1

As shown in fig. 1-4, the present invention provides a normal temperature and low temperature liquid evaporation device, which comprises a casing 100 and an evaporation module 200; the housing 100 is provided with a liquid inlet 101 and a liquid outlet 102, and the top of the housing is also provided with a light-gathering glass 104. The evaporation module 200 includes a rotation shaft 210, a slot body 211, a fan-shaped piece 220, and a moisture absorption film 221. In addition, the device also comprises a driving device 301 for driving the rotating shaft to rotate and a liquid collecting device 302 which is communicated with the shell and is used for collecting the evaporated liquid.

As shown in fig. 1-4, the housing 100 is for containing a liquid to be evaporated and is of a closed configuration. A liquid inlet 101 and a liquid outlet 102 for the liquid to be evaporated to enter and exit are provided on the casing 100; a rotating shaft 210 is arranged in the shell, and a slot body 211 is arranged on the rotating shaft 210 so as to facilitate the installation, fixation and disassembly of the fan-shaped piece 220; the moisture absorption film 221 is coated on the surface of the fan-shaped sheet 220 and is made of a porous nano material, the main chemical components are cobalt chloride and ethanolamine, the moisture absorption film can rapidly absorb moisture and rapidly release moisture under illumination, and different color changes are generated according to the moisture absorption degree. The light-focusing glass 104 is installed on the top of the housing and is composed of a plurality of light-focusing glasses installed horizontally or at a certain angle.

The liquid evaporation device more specifically operates as follows:

in the embodiment, the driving device 301 and the liquid collecting device 302 are arranged to drive the rotating shaft 210 to rotate and collect the evaporated liquid, and the main component of the liquid to be evaporated is mainly moisture. A quantity of liquid to be evaporated is stored in the lower part of the housing through the liquid inlet 101 and forms a liquid level, which in this embodiment is located at about the level of the rotating shaft 210. Under the driving of the driving device, the rotating shaft 210 drives the fan-shaped sheet 220 to rotate at a speed of 5-10 rpm, due to the existence of the moisture absorption film 221, the liquid to be evaporated can quickly wet the film and form a liquid film on the surface of the film, and in addition, because the moisture absorption film 221 is a hydrophilic film prepared from a porous nano material, the inside of the film has a very large specific surface area, and the liquid to be evaporated can be soaked into the inside of the film and stored in a porous structure inside the film. At the moment, sunlight is directly irradiated on the condensing glass 104, the converged light is gathered on the moisture absorption film 221 through the convex lens effect on the condensing glass 104, liquid on the surface of the film is quickly evaporated, liquid to be evaporated stored in the film is gradually consumed, and the irradiated film part rotates in the fan-shaped piece to enter the liquid level and then is soaked in new liquid to be evaporated again. The liquid can be evaporated very efficiently by circulating the above steps. According to the judgment of the color change degree of the moisture absorption film 221, the fan-shaped sheet on the slot body 211 is selectively detached, and a new moisture absorption film 221 is replaced, so that the operation is very convenient and fast. Finally, the evaporated moisture is collected by the moisture collection device 302, completing the solid-liquid separation process of the liquid to be evaporated.

In this application example, the working efficiency of the liquid evaporation device is affected by the weather. The higher the sunlight intensity is, the higher the temperature is, and the higher the evaporation efficiency is; conversely, rainy weather can reduce the operating efficiency of the evaporator. In addition, the operating efficiency of the evaporator is also affected by the number and size of the segments. The larger the area of the fan-shaped pieces is, the larger the number of the fan-shaped pieces is, and more moisture absorption films 221 can be coated, which further improves the evaporation efficiency.

Example 2

Fig. 5 shows still another embodiment of the liquid evaporation device, which is substantially the same in structure as the liquid evaporation device of embodiment 1. The liquid to be evaporated enters the shell through the liquid inlet and is stored at the bottom of the shell, and efficient evaporation is realized through the light condensation effect of the light condensation glass and the effect of fast absorbing and releasing moisture of the moisture absorption film 221.

The operation principle and the process of the embodiment are the same as those of the embodiment 1, and the difference is that the angle between the condensing glass at the top of the shell and the horizontal plane is 45 degrees, so that the sunlight can be intensively used for irradiating, the sunlight passing through the condensing glass can be accurately irradiated on the moisture absorption film, and the evaporation efficiency is further improved.

Example 3

Fig. 6 shows still another embodiment of the liquid evaporation device, which is substantially the same in structure as the liquid evaporation device of embodiment 1. The liquid to be evaporated enters the shell through the liquid inlet and is stored at the bottom of the shell, and efficient evaporation is realized through the condensation effect of the condensation glass and the effect of fast absorbing and releasing moisture of the moisture absorption film.

The operation principle and process of this application example are the same as those of embodiment 1, except that the number of the segments mounted on the socket body 211 is changed. As shown in fig. 6, when the amount of liquid to be evaporated is small, only the outer ring of the fan-shaped piece and the film may be selectively installed. This has the following benefits: (1) the consumption of the moisture absorption film is saved, and the evaporation cost is reduced; (2) the phenomenon that the forming of the liquid film is influenced because a small amount of liquid to be evaporated infiltrates into the inner ring moisture absorption film through the liquid film is reduced, and the evaporation efficiency is further reduced.

Example 4

Fig. 7 shows still another embodiment of the liquid evaporation device, which is substantially the same in structure as the liquid evaporation device of embodiment 1. The liquid to be evaporated enters the shell through the liquid inlet and is stored at the bottom of the shell, and efficient evaporation is realized through the condensation effect of the condensation glass and the effect of fast absorbing and releasing moisture of the moisture absorption film.

The operation principle and process of this embodiment are the same as those of embodiment 1, except that the weather condition set in this embodiment is cloudy, and the halogen tungsten lamp 103 at the top of the housing is turned on. When no sun is irradiated, the condensing glass positioned at the top end of the shell cannot play the function of the shell, and the evaporation efficiency is greatly reduced. Turning on the halogen tungsten lamp simulates the sunlight provided by the sun and reduces the loss of evaporation efficiency to some extent.

Example 5

Fig. 8 shows still another embodiment of the liquid evaporation device, which is substantially the same in structure as the liquid evaporation device of embodiment 1. The liquid to be evaporated enters the shell through the liquid inlet and is stored at the bottom of the shell, and efficient evaporation is realized through the condensation effect of the condensation glass and the effect of fast absorbing and releasing moisture of the moisture absorption film.

The operation principle and process of this application example are the same as those of embodiment 1, except that the number of the rotating shafts 210 is changed from 1 to a plurality of shafts, and the number of the liquid inlets and outlets is changed from 1 to a plurality of shafts accordingly. In addition, the volume of the housing is also increased accordingly. The bottom of the housing is divided into a plurality of zones for storing different liquids. This structure can be used for evaporating different liquid simultaneously, realizes the promotion in the efficiency.
