Description

Technical Field

[0001] This utility model relates to the field of liquid carbon dioxide gasification technology, and in particular to a high-pressure, high-temperature liquid carbon dioxide gasification device. Background Technology

[0002] Liquid carbon dioxide refers to carbon dioxide gas liquefied into a liquid form under high pressure and low temperature. Liquid carbon dioxide is a refrigerant that can be used to preserve food and for artificial rainmaking. It is also an industrial raw material that can be used to produce soda ash, urea, and soft drinks. Carbon dioxide is compressed and liquefied at the gas source and filled into gas cylinders before being transported to the place of use. Before use, it needs to be vaporized into gaseous carbon dioxide by a vaporization device.

[0003] Common high-pressure, high-temperature vaporization devices for liquid carbon dioxide have relatively simple structures. They typically involve heating the outside of the vessel to increase the temperature of the liquid carbon dioxide inside. This heating method is uneven, which leads to a decrease in vaporization efficiency. Therefore, we propose a high-pressure, high-temperature vaporization device for liquid carbon dioxide.

[0033] Example 1

[0034] like Figure 1-4 As shown, this utility model provides a technical solution: a high-pressure, high-temperature vaporization device for liquid carbon dioxide, including a housing 1, a heating component 2 installed inside the housing 1, a liquid injection pipe 101 installed near the front of the top of the housing 1, an air inlet pipe 102 installed near the back of the top of the housing 1, and a plurality of exhaust components 103 installed at equal intervals at the top of the housing 1 between the liquid injection pipe 101 and the air inlet pipe 102. A heating groove 104 is provided inside the housing 1 near the bottom. The heating component 2 includes a motor 201, which is fixedly installed inside the housing 1. The output end of the motor 201 is fixedly connected to a stirring rack 202, and a heating rod 203 is installed inside the stirring rack 202.

[0035] Example 2

[0036] like Figure 1-4As shown, adjustable feet 105 are installed at the bottom of the chamber 1 near the four corners. By rotating the adjustable feet 105, the horizontal position of the chamber 1 can be adjusted to prevent the liquid carbon dioxide inside the chamber 1 from tilting, thus improving stability. A control panel 106 is installed on the back of the chamber 1. The control panel 106 is electrically connected to the motor 201 and the heating rod 203. The motor 201 and the heating rod 203 can be controlled through the control panel 106, improving ease of use. A pressure sensor 107 is installed inside the chamber 1 near the back. The pressure sensor 107 is electrically connected to the control panel 106. The pressure sensor 107 can monitor the gas pressure inside the chamber 1 and transmit the pressure information to the control panel 106 in real time, improving ease of use. The exhaust assembly 103 includes an exhaust pipe 1031, which is installed at the top of the chamber 1 for exhaust. A safety valve 1032 is fixedly installed at one end of the pipe 1031 extending into the interior of the box 1. The vaporized carbon dioxide can be output from the interior of the box 1 through the exhaust pipe 1031. The safety valve 1032 can vaporize the liquid carbon dioxide under a certain pressure. After the gas pressure inside the box 1 reaches the threshold, the vaporized carbon dioxide is discharged through the exhaust pipe 1031. The heating tank 104 has a semi-circular arc structure. The left and right sides of the box 1 are respectively connected to the heating tank 104 by the water inlet pipe 1041 and the water outlet pipe 1042. Hot water can be injected into the heating tank 104 through the water inlet pipe 1041 to assist in heating the liquid carbon dioxide. The hot water is then discharged through the water outlet pipe 1042 to achieve a circulation effect. The stirring rack 202 is made of metal copper. Its end near the front is rotatably connected to the box 1. Metal copper has high thermal conductivity, which can reduce heat loss and improve the heating effect.

[0037] The working process of this utility model is as follows: When using a high-pressure, high-temperature liquid carbon dioxide vaporization device for liquid carbon dioxide vaporization, gas is first injected into the housing 1 through the gas inlet pipe 102. The gas pressure is monitored in real time by the gas pressure sensor 107 to ensure that the gas pressure inside the housing 1 reaches a value that allows the liquid carbon dioxide to remain stable. Then, liquid carbon dioxide is injected into the housing 1 through the liquid injection pipe 101. When high-pressure, high-temperature vaporization is required, hot water is injected into the heating tank 104 through the water inlet pipe 1041. After the heating tank 104 is full, the hot water is discharged through the water outlet pipe 1042, allowing the hot water to circulate and maintain heat. The water temperature is controlled by the control panel 106, which controls the heating rod 203 to start heating and the motor 201 to rotate. The motor 201 drives the stirring rack 202 to rotate, stirring and heating the liquid carbon dioxide in the chamber 1, accelerating the vaporization of the liquid carbon dioxide. When the liquid carbon dioxide vaporizes, the air pressure inside the chamber 1 will rise rapidly. When the threshold of the safety valve 1032 is reached, the safety valve 1032 will automatically open, allowing the vaporized carbon dioxide to be discharged through the exhaust pipe 1031, completing the entire vaporization process. Compared with traditional heating methods, this greatly improves the heating uniformity and effectively improves the vaporization efficiency.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
