An oxygen-enriched water bath vaporizer

Abstract

This utility model provides an oxygen-enriched water bath vaporizer, relating to the field of vaporizer technology. It includes an inner tank fixedly installed inside an outer tank. A temperature sensor is fixedly installed on the left side of the outer tank, with its right end located inside the inner tank. An electric heating block is fixedly installed on the inner bottom wall of the inner tank, and an extraction nozzle is fixedly installed on the right side of the outer tank. This oxygen-enriched water bath vaporizer uses the extraction nozzle to evacuate air from the hollow area formed by the outer and inner tanks, creating a vacuum in the hollow area. This reduces the interference of external temperature changes on the water inside the inner tank. The temperature sensor monitors the water temperature, and in cold weather, the electric heating block heats the water to a temperature within the vaporization range, facilitating the conversion of liquid oxygen into gaseous form through the vaporization pipe. This prevents freezing during the vaporization process and ensures normal gas supply even in cold weather.

Description

Technical Field

[0001] This utility model relates to the field of gasifier technology, specifically to an oxygen-enriched water bath gasifier. Background Technology

[0002] Cryogenic fluid vaporizers come in various forms, and based on their structure and working principle, they can generally be divided into ambient temperature vaporizers and water bath vaporizers. They are mainly used for the vaporization of cryogenic fluids such as liquid nitrogen, liquid oxygen, liquefied natural gas, and liquefied petroleum gas, that is, converting cryogenic liquids into ambient temperature gases to meet applications in transportation, steel, chemical, electronics, and cutting industries. Water bath vaporizers typically achieve vaporization by exchanging heat between external hot water and the cryogenic liquid, greatly improving the heat exchange efficiency per unit area.

[0003] In cold weather such as winter, water bath vaporizers are prone to insufficient gas supply due to poor heat exchange. When low-temperature fluid enters the vaporizer, especially during cold start-up, the heat exchange coils are prone to freezing, resulting in low heat exchange efficiency and affecting normal use.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] This utility model embodiment provides an oxygen-enriched water bath type vaporizer, such as... Figure 1-4As shown, the system includes an inner tank 8 fixedly installed inside the outer tank 1. A temperature sensor 4 is fixedly installed on the left side of the outer tank 1, and the right end of the temperature sensor 4 is located inside the inner tank 8. An electric heating block 9 is fixedly installed on the inner bottom wall of the inner tank 8. An air extraction nozzle 7 is fixedly installed on the right side of the outer tank 1. A vaporization pipe 10 and a heat exchange pipe 11 are fixedly installed on the inner side of the inner tank 8. A circulating hot water pump 12 for balancing the water temperature is fixedly installed on the right side of the outer tank 1.

[0023] In this embodiment, by setting up an air extraction nozzle 7, an electric heating block 9, and a circulating hot water pump 12, it is convenient to extract air from the hollow area formed by the outer tank 1 and the inner tank 8 through the air extraction nozzle 7, so that the hollow area forms a vacuum state, reducing the interference of external temperature changes on the water in the inner tank 8. The water temperature is monitored by the temperature sensor 4, and the water is heated by the electric heating block 9. The water is circulated by the circulating hot water pump 12, so that the water temperature can be kept relatively balanced, which facilitates the conversion of liquid oxygen into gaseous form through the vaporization pipe 10.

[0024] A pumping pipe 13 for pumping water is fixedly installed at the bottom of the circulating hot water pump 12, and a drain pipe 14 for draining water is fixedly installed at the top of the circulating hot water pump 12.

[0025] In this embodiment, by setting up a water pumping pipe 13 and a drain pipe 14, it is convenient to use the circulating hot water pump 12 to draw water heated at the bottom of the inner tank 8 through the water pumping pipe 13 and discharge it to the top of the inner tank 8 through the drain pipe 14, so that the water temperature can be kept balanced, which is convenient for the liquid oxygen to be vaporized and converted into oxygen through the vaporization pipe 10 for use.

[0026] One end of the vaporization tube 10 is fixedly installed with a liquid inlet connector 2, and the other end of the vaporization tube 10 is fixedly installed with an exhaust connector 3. The vaporization tube 10 has a spiral structure. One end of the heat exchange tube 11 is fixedly installed with a first connector 5, and the other end of the heat exchange tube 11 is fixedly installed with a second connector 6. The heat exchange tube 11 has a W-shaped structure.

[0027] In this embodiment, by setting up a vaporization pipe 10, liquid oxygen is input from the liquid inlet connector 2, and oxygen that has been vaporized and converted through the vaporization pipe 10 is discharged through the exhaust connector 3 for use. By setting up a heat exchange pipe 11, it is convenient to utilize the heat energy available on site. When there is warm water generated by the compressor used by the air separation system, the warm water can be injected through the first connector 5, exchanged with the water in the inner tank 8 through the heat exchange pipe 11, and then discharged through the second connector 6, making better use of energy. When there is boiler hot gas, the first connector 5 can also be connected to the hot gas generated by the boiler for recycling and utilization, making better use of heat energy.

[0028] A spiral heat-conducting fin 16 is fixedly installed on the outside of the vaporization tube 10, and a strip heat-conducting fin 15 is fixedly installed on the outside of the heat exchange tube 11.

[0029] In this embodiment, by setting spiral heat-conducting plates 16 and strip heat-conducting plates 15, the heat flowing inside the heat exchange tube 11 can be better exchanged with the strip heat-conducting plates 15 to heat the water. In conjunction with the spiral heat-conducting plates 16 on the outside of the vaporization tube 10 to exchange heat with the warm water in the inner tank 8, the liquid oxygen entering the vaporization tube 10 can be better absorbed and vaporized into oxygen, thereby facilitating better normal gas supply and use.

[0030] The electric heating block 9 is located below the vaporization tube 10, and the heat exchange tube 11 is located at the center of the vaporization tube 10.

[0031] In this embodiment, the electric heating block 9 is positioned below the vaporization tube 10 to heat the area of ​​the vaporization tube 10 near the liquid inlet connector 2 where liquid oxygen is injected, thus preventing the vaporization tube 10 from freezing during low-temperature cold start. The heat exchange tube 11 is positioned inside the vaporization tube 10, which facilitates rapid contact between the heat exchange tube 11 and the vaporization tube 10 and the spiral heat-conducting plate 16 after heat exchange with water, making it easier to utilize the heat exchanged between the heat exchange tube 11 and the water.

[0032] Working principle: In use, the air is first evacuated through the air extraction nozzle 7 to create a vacuum in the hollow area formed by the outer tank 1 and the inner tank 8, reducing the interference of external temperature changes on the water in the inner tank 8. The water temperature is monitored by the temperature sensor 4. When the water temperature is low, the water is heated by the electric heating block 9. Then, the water heated at the bottom of the inner tank 8 is extracted through the water extraction pipe 13 and discharged to the top of the inner tank 8 through the drain pipe 14, so that the water temperature can be kept relatively balanced, which facilitates the conversion of liquid oxygen into gaseous form through the vaporization pipe 10 for normal gas supply.
