Problems solved by technology

However, due to the rectification production of deuterium-depleted water, a relatively large reflux ratio is required, and each ton of deuterium-depleted water needs to consume several tons to tens of tons of industrial steam, which also has the disadvantage of high energy consumption.

preparation example Construction

[0040] A method for preparing deuterium-depleted water, comprising the following steps:

[0041] The preheated or non-preheated feed enters the gas-liquid separation device for rectification operation, and the gas phase material flowing out from one end (top) of the gas-liquid separation device enters the first heating device, then heats and pressurizes, and then enters the second heating In the built-in heat exchange parts of the device;

[0042] The material flowing out from the bottom of the gas-liquid separation device is extracted from the bottom of the gas-liquid separation device in the form of bottom discharge. It can be selectively heated and then returned to the gas-liquid separation device, or it can be directly recovered without heating. The material flowing out from the bottom of the liquid separation device enters the second heating device in another way and does not contact the material in the heat exchange element. The material in the heat exchange element is u...

Embodiment 1

[0045] Such as Figure 2-4 As shown, a deuterium-depleted water preparation device includes a gas-liquid separation device, a first heating device, a second heating device and a third heating device, the gas-liquid separation device is a rectification tower 3, and the first heating device is a vapor compression The pump 4, the second heating device is a reboiler 1, the built-in heat exchange element of the reboiler 1 is a W-shaped heat exchange tube 5, the third heating device is a heat exchanger 6, and the curved heat exchanger built in the third heating device The heat pipe 8 is W-shaped, the top of the rectification tower 3 is connected to the vapor compression pump 4 and then connected to the top of the heat exchange tube 5 built in the reboiler 1, and the bottom of the heat exchange pipe 5 is connected to the top of the rectification tower 3 Connected, used to return the material in the heat exchange tube 5 to the rectification tower 3 through the top of the rectification...

Embodiment 2

[0056] Such as Figure 2-3 and Figure 5 As shown, a deuterium-depleted water preparation device includes a gas-liquid separation device, a first heating device, a second heating device and a third heating device. The difference between this embodiment 2 and embodiment 1 is that this embodiment 2 is The upstream of the liquid separation device is provided with two third heating devices arranged in parallel and connected sequentially from end to end, and in this embodiment 2, the feed enters another heat exchanger after being heat-exchanged by the heat exchanger 6 farthest from the rectification tower 3 6, and then enter the rectification tower 3, the material flowing out from the bottom of the gas-liquid separation device is extracted from the bottom kettle or the bottom of the rectification tower 3 in the form of bottom discharge, and then sent to the third heating station closest to the gas-liquid separation device The device is preheated before discharge.

[0057] The gas...

Abstract

The invention discloses a deuterium-depleted water preparation device, a preparation method and application. According to the deuterium-depleted water preparation device, one end of a gas-liquid separation device communicates with one end of a heat exchange piece through a first heating device, the other end of the heat exchange piece communicates with a gas-liquid separation device, and the otherend of the gas-liquid separation device communicates with a second heating device and does not communicate with the heat exchange piece; and the material from the gas-liquid separation device and positioned outside the heat exchange piece exchanges heat with the material in the heat exchange piece in the second heating device. According to the deuterium-depleted water preparation device, the preparation method and the application, materials flowing out of the top of the gas-liquid separation device do not need to be cooled and can be directly compressed, heated and pressurized to serve as a heat source for subsequent material heating, energy recycling is achieved, and the materials flowing out of the bottom of the gas-liquid separation device can be directly extracted or flow back to thegas-liquid separation device, circulation heat exchange can be carried out, the deuterium-depleted water production rate is greatly improved, loss-free feeding is basically achieved, the defects of industrial amplification and high energy consumption are avoided, the production target of near-zero energy consumption and high yield is achieved, and deuterium-depleted water or distilled water can beprepared.

Description

technical field [0001] The invention belongs to the technical field of deuterium-depleted water or distilled water preparation, and in particular relates to a deuterium-depleted water preparation device, preparation method and application. Background technique [0002] Deuterium-depleted water refers to water in which the deuterium content in water is lower than that in natural water (natural deuterium content is generally 150-155ppm), especially water with deuterium content less than 135ppm. In areas with higher altitudes in nature, there will also be a slight decrease in deuterium content, but generally not much. [0003] At present, many studies have shown that deuterium-depleted water has obvious effects in the fields of adjuvant treatment of tumors, improvement of nervous system diseases, and enhancement of immunity. It is one of the current research hotspots. However, the high production cost of deuterium-depleted water has become one of the key factors restricting it...
