Description

Technical Field

[0001] This utility model belongs to the field of chemical equipment technology, specifically relating to a device for improving the solubility of carbon dioxide. Background Technology

[0002] For example, Chinese patent application CN202320583566.6 describes a simple carbonated water preparation device. "The preparation device includes at least one set of Venturi tubes and a nanoemulsifying pump. The Venturi tubes have a gas inlet, a liquid inlet, and an outlet. The liquid inlet and outlet are on the same axis. The gas inlet is used to introduce pressurized carbon dioxide, and the liquid inlet is used to introduce pressurized purified water. The inlet of the nanoemulsifying pump is connected to the outlet of the Venturi tubes, and the mixed solution output by the nanoemulsifying pump is connected to a water storage tank." Its principle is to initially mix carbon dioxide and purified water through the Venturi tubes and accelerate its input into the nanoemulsifying pump. The nanoemulsifying pump then rapidly and thoroughly disperses and mixes the initially mixed carbon dioxide and purified water through its internal high-speed rotor. However, this device has a complex structure, is not easily integrated with smaller equipment, has a limited range of compatibility, and its components are tightly connected, making later maintenance difficult. Utility Model Content

[0003] The present invention aims to solve the technical problems existing in the prior art and provide a device for improving the solubility of carbon dioxide.

[0004] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: A device for improving carbon dioxide solubility includes an integrated module. A liquid inlet is provided on one side of the integrated module, extending into the integrated module. A first through hole is provided on the top side of the integrated module above the liquid inlet, opening downward and communicating with the liquid inlet. A gas-liquid outlet is provided on the other side of the integrated module opposite the liquid inlet, extending into the integrated module. A second through hole is provided above the gas-liquid outlet, opening downward and communicating with the gas-liquid outlet. A connecting cavity is provided between the first and second through holes, located inside the integrated module. An adapter is threaded to the top of the first through hole. A gas inlet is provided at the center of the adapter. A gas diffuser is threaded to the bottom of the adapter. A first gas chamber communicating with the gas inlet is provided at the center of the gas diffuser. A second gas chamber separated from the first gas chamber is provided inside the gas diffuser. The partition between the first and second gas chambers and the outer surface of the gas diffuser are both porous structures.

[0005] Preferably, the integrated module is fitted with multiple bolts for installation and fixation.

[0006] Preferably, threads are provided at both ends of the first through hole, the second through hole, the liquid inlet, the gas-liquid outlet, and the return channel for auxiliary installation.

[0007] Preferably, the bottom of the first through hole extends downward to form a gas collecting channel, the bottom of the gas diffuser extends into the gas collecting channel, and the bottom of the second through hole extends downward to form a conical bottom cavity.

[0008] Preferably, an auxiliary cavity is formed at the connection between the adapter and the gas diffuser, and a mounting gasket is fitted onto the top surface of the gas diffuser.

[0009] The beneficial effects of this utility model are as follows: This structure is installed through a compact integrated module, which facilitates installation, disassembly, and replacement. The return channel can be connected to the liquid inlet through an external pipeline to change the liquid flow direction. At the same time, an adapter inserted into the first through hole at the top connects to an external gas line. The adapter is installed by a threaded connection, and different models of adapters can be used to connect to the external gas line. The structure is also more convenient to disassemble and replace. Meanwhile, the gas diffuser at the bottom is installed on the inner thread of the adapter by a threaded connection, which makes subsequent structural replacement very quick and convenient. The gas is delivered to the gas diffuser and diffuses out from the sides and bottom through the first and second gas chambers. The aeration effect is further enhanced by the two aerations. The gas is deeply mixed with the solution in the gas collection channel. An external pressure sensor is inserted into the second through hole to facilitate pressure testing of the internal gas-liquid mixture and facilitate internal pressure control.

Detailed Implementation

[0015] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0016] Example: A device for increasing the solubility of carbon dioxide, such as Figures 1-4 As shown, the system includes an integrated module 1. A liquid inlet 16 is provided on one side of the integrated module 1, extending inwards. A first through-hole 13 is provided on the top of the integrated module 1 above the liquid inlet 16, opening downwards and communicating with the liquid inlet 16. The bottom of the first through-hole 13 extends downwards to form a gas collecting channel 131. The bottom of the gas diffuser 3 extends into the gas collecting channel 131. The gas collecting channel 131 extends downwards, increasing the depth of liquid flow and providing more space for gas-liquid mixing with the gas diffuser 3. A gas-liquid outlet 17 is provided on the other side of the integrated module 1 opposite the liquid inlet 16, extending inwards. A second through-hole 14 is provided above the gas-liquid outlet 17, opening downwards and communicating with the gas-liquid outlet 17. The two through holes are interconnected. The bottom of the second through hole 14 extends downward to form a conical bottom cavity 141, which facilitates the insertion of an external pressure sensor. A connecting cavity 15 is provided between the first through hole 13 and the second through hole 14. The connecting cavity 15 is located inside the integrated module 1 and is mainly used for buffering the gas-liquid mixture at the front and for conveying it to the rear until it is discharged through the gas-liquid outlet 17. The top of the first through hole 13 is threaded with an adapter 2. The adapter 2 can be of different models according to requirements. A gas inlet 21 is provided at the center of the adapter 2. A gas diffuser 3 is threaded at the bottom of the adapter 2. A first gas chamber 31 communicating with the gas inlet 21 is provided at the center of the gas diffuser 3. A second gas chamber 32 separated from the first gas chamber 31 is provided inside the gas diffuser 3. The partition between the first gas chamber 31 and the second gas chamber 32 and the outer surface of the gas diffuser 3 are all porous structures.

[0017] The integrated module 1 is fitted with multiple bolts 11 for installation and fixing. The integrated module 1 can be easily installed on the equipment to be used by means of the bolts 11. Installation and disassembly are convenient. The first through hole 13, the second through hole 14, the liquid inlet 16, the gas-liquid outlet 17 and the two ports of the return channel 12 are all threaded for auxiliary installation, so that the installation position is in advance when connecting to the external pipeline.

[0018] An auxiliary cavity 4 is formed at the connection between the adapter 2 and the gas diffuser 3. A mounting gasket 41 is fitted onto the top surface of the gas diffuser 3 to increase the tightness of the connection between the gas diffuser 3 and the adapter 2.

[0019] The principle of this invention is as follows: Liquid enters through liquid inlet 16, and gas enters through gas inlet 21 in adapter 2. After being fully and evenly aerated twice by gas diffuser 3, the gas diffuses and distributes. The gas first enters the first gas chamber 31, and after the first aeration, it enters the second gas chamber 32. Finally, it is discharged through the multiple holes on the outer surface and bottom of gas diffuser 3. The contact area between uniform small bubbles and liquid is further expanded, and the gas utilization efficiency is increased. The gas can be pressurized in the early stage. Carbon dioxide at a certain pressure has a greater solubility in liquid. The liquid and the bubbles passing through gas diffuser 3 are deeply fused, and then transported to the connecting cavity 15 and finally flow out through gas-liquid outlet 17.

[0020] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and many variations are possible. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
