Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of equipment for deuterating products using high-concentration heavy water, and relates to a heavy (deuterium) water concentrator that increases the deuterium concentration after deuterating high-concentration heavy water. Background Technology
[0002] Industries that use high-value, high-concentration heavy water to manufacture products face a serious problem: as the number of uses and time increase, the deuterium concentration of the heavy water gradually decreases, and it can no longer be used once it drops to a certain level.
[0003] If you want to continue using these old, low-concentration heavy waters, you must purchase heavy water with a high deuterium content and mix it to increase the deuterium content so you can continue using it as is.
[0004] In reality, mixing heavy water can only solve the problem temporarily; over time and with repeated mixing, the amount of low-concentration heavy water increases exponentially, making it impossible to purchase large quantities of high-concentration heavy water for mixing. Summary of the Invention
[0005] The purpose of this invention is to solve the above-mentioned problems and provide a heavy water concentrator.
[0006] To achieve the above objectives, the present invention provides a heavy water concentrator, including a concentration tank, an exhaust pipe connected to the top of the concentration tank, the other end of the exhaust pipe connected to a combustion chamber, a recovery vessel connected to the combustion chamber via a pipe, a cooling device provided around the combustion chamber, an electrode plate provided inside the concentration tank for electrolyzing low-concentration heavy water, and an electromagnetic stirrer provided at the bottom of the concentration tank for driving away air bubbles on the surface of the electrode plate, accelerating the convection of the electrolyzed heavy water, and improving the electrolysis efficiency.
[0007] Furthermore, the cooling device includes: Cooling water tank, containing cooling water; The cooling circuit is located on the outer periphery of the combustion chamber and has a return pipe connected to the cooling box; The water pump is connected to the cooling water tank at one end and the cooling circuit at the other end, and is used to transport the cooling water in the cooling water tank to the cooling circuit.
[0008] Furthermore, the low-concentration heavy water concentration process is as follows: Low-concentration heavy water is placed in a concentration tank and electrolyzed using electrode plates. The electrolyzed deuterium, hydrogen, and oxygen rise upwards through the outlet pipe into the combustion chamber, while the water pump delivers the cooling water from the cooling water tank to the cooling circuit and then back to the cooling tank through the return pipe to form a cooling water flow. At this time, deuterium, hydrogen and oxygen are mixed and burned in the combustion chamber to form water vapor, which is then condensed and collected in the recovery container; The collected material in the recovery vessel can be placed back into the concentration tank to repeat the above process to obtain the desired concentration.
[0009] Furthermore, the concentration tank is equipped with a pressure sensor to control the electrolysis power supply to be turned on or off.
[0010] The beneficial effects of this invention are as follows: This invention utilizes electrolysis to recover low-concentration heavy water through electrolysis-combustion-condensation, thereby effectively increasing the concentration of heavy water and enabling its regeneration.
[0011] The cooling device of this invention can form a circulating cooling water flow around the combustion chamber, which can promptly remove the heat generated by combustion, promote the rapid condensation of water vapor, improve the recovery efficiency, and at the same time ensure the stable operating temperature of the combustion chamber and extend the service life of the equipment.
[0012] This invention has a simple structure and safe operation. It can flexibly obtain the required concentration of heavy water through multiple cycles, which greatly reduces the enterprise's dependence on purchasing high-concentration heavy water and has significant economic benefits. Attached Figure Description
[0013] Figure 1 The diagram schematically illustrates the structure of a low-deuterium heavy water concentrator according to one embodiment of the present invention. Detailed Implementation
[0014] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the embodiments will be briefly described below. Obviously, the drawings described below are merely some embodiments of the present invention, and those skilled in the art can obtain other drawings based on these drawings without creative effort.
[0015] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The embodiments cannot be described in detail here, but the embodiments of the present invention are not limited to the following embodiments.
[0016] like Figure 1As shown, this invention provides a low-deuterium heavy water concentrator, including a concentration tank 1 made of pressure-bearing and corrosion-resistant material. An outlet pipe 2 is connected to the top of the concentration tank 1, and the other end of the outlet pipe 2 is connected to a combustion chamber 3. The combustion chamber 3 is connected to a recovery vessel 4 via a pipe, and a cooling device 5 is provided around the outer periphery of the combustion chamber 3. Electrode plates 11 are installed inside the concentration tank 1 to electrolyze low-concentration heavy water. A magnetic stirrer 12 is installed at the bottom of the concentration tank 1. The magnetic stirrer 12 promotes solution convection and drives away air bubbles on the electrode plates 11, preventing air bubbles from accumulating on the electrode plates 11 and affecting the electrolysis effect. A pressure sensor 13 is installed on the concentration tank 1 to control the electrolysis power supply to turn on or off as a safety protection measure.
[0017] According to one embodiment of the present invention, the cooling device 5 includes a cooling water tank 51, a cooling circuit 52, and a water pump 53. The cooling water tank 51 contains cooling water, and the cooling circuit 52 is disposed on the outer periphery of the combustion chamber 3 and has a return pipe 521 connected to the cooling tank 51. One end of the water pump 53 is connected to the cooling water tank 51, and the other end is connected to the cooling circuit 52, for transporting the cooling water in the cooling water tank 51 to the cooling circuit 52.
[0018] The process of concentrating low-concentration heavy water using the heavy water concentrator of the present invention is as follows: Low-concentration heavy water is placed in a concentration tank 1 and electrolyzed by working through electrode plates 11. The electrolyzed deuterium, hydrogen, and oxygen rise upwards through the outlet pipe 2 and enter the combustion chamber 3. At the same time, the water pump delivers the cooling water from the cooling water tank 51 to the cooling circuit 52 and then returns it to the cooling tank 51 through the return pipe 521 to form a cooling water flow. At this time, deuterium, hydrogen and oxygen in combustion chamber 3 are mixed and burned to form water vapor, which is then condensed and collected in recovery container 4; The collected liquid in recovery vessel 4 is injected back into concentration tank 1, and the above electrolysis-combustion-condensation cycle is repeated. With each cycle, the heavy water concentration can be further increased. Depending on actual needs, this process can be repeated several times until the heavy water concentration reaches the desired level.
[0019] The above description is merely one embodiment of the present invention and is not intended to limit the invention. Those skilled in the art will recognize that the present invention can be modified and varied in various ways. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
