Description

Technical Field

[0001] The invention relates to the technical field of water bath vaporizers, in particular to an energy-saving water bath vaporizer. Background Art

[0002] A water bath vaporizer is a device used to heat and vaporize liquids, especially in applications where liquid gases need to be converted into gases. It heats the liquid in a water bath to bring it to the temperature required for vaporization, usually through a water heater. The water temperature of the water bath can be precisely controlled to meet the vaporization requirements of different liquids.

[0003] At present, the gasification of liquid nitrogen is mainly carried out through a water bath vaporizer, which converts liquid gas into gas by heating. Its working principle is based on heating liquid, providing heat through a water bath to vaporize the liquid. When the water bath vaporizer is out of use, since the water bath vaporizer is mainly used to heat liquid rather than liquefy gas, the gas needs to be liquefied by lowering the temperature or increasing the pressure, and the existing water bath vaporizer does not have an effective cooling system, so the vaporized liquid in the water bath vaporizer cannot be recovered and stored, and the gas retained in the water bath vaporizer will gradually escape after being out of use for too long, resulting in a waste of resources.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1.

When liquid nitrogen needs to be converted into gas, first water is delivered to the vaporization chamber and heated, and then the delivery pump is started to deliver the liquid nitrogen to the threaded pipe.

[0032] In this embodiment, when liquid nitrogen needs to be converted into gaseous state, firstly, the external water source conveying device is connected to the water inlet pipe 202, and then the external water source is conveyed to the inside of the gasification bin 201. At the same time, the heating coil 207 is electrically connected to the external power supply to release heat to the outside, heat the water source in the gasification bin 201, and control the temperature of the water source in the gasification bin 201 through the temperature sensor 208. The temperature sensor 208 is composed of a contact formed by two different metal contacts. When the temperature of the contact changes, a voltage proportional to the temperature is generated. This voltage signal can be measured and converted into a temperature signal. The temperature is set to a certain value, and then the delivery pump 203 is started to drive the liquid inlet pipe 204 to extract liquid nitrogen from the storage tank 206. The liquid nitrogen enters the threaded pipe 210 through the liquid outlet pipe 205. The spiral shape of the threaded pipe 210 increases the contact area between the liquid nitrogen and the hot water in the gasification bin 201, so that the liquid nitrogen is heated and gasified and moves upward to enter the gasification pipe 212. Then, the gas outlet pipe 213 is connected to the external nitrogen pipeline, and the solenoid valve 214 is opened at the same time, so that the nitrogen in the gasification pipe 212 can be transported outward for use by the external setting. When the external setting does not need to use nitrogen, the solenoid valve is closed first. 214 and the delivery pump 203, start the centrifugal pump 303, and extract gas into the negative pressure chamber 302 through the delivery pipe 304, so that a negative pressure state is formed in the negative pressure chamber 302. In order to prevent the rotating plate 309 from rotating toward the inside of the negative pressure chamber 302 under the influence of the negative pressure, the electromagnet 312 is electrically connected to the external power supply to generate a magnetic field to adsorb the iron block 311, so that the rotating plate 309 is parallel to the inner wall of the L-shaped groove 307. The outer surface of the rotating plate 309 is made of rubber material, which has a certain elasticity and thus has a good sealing performance. The inner wall of the groove 307 overlaps, thereby sealing the negative pressure chamber 302. When the pressure sensor 305 detects that the negative pressure value in the negative pressure chamber 302 reaches the required value, the pressure sensor 305 uses the resistance change of the piezoelectric effect. When pressure is applied to the sensor, the sensitive element in the sensor will deform, causing its resistance to change. The amount of resistance change is proportional to the applied pressure. Then, the electromagnet 312 is disconnected from the external power supply, so that the electromagnet 312 no longer adsorbs the iron block 311, so that the rotating plate 309 rotates toward the inside of the negative pressure chamber 302 under the action of the negative pressure. Figure 6As shown, the limiting tube 308 is connected to one side of the rotating plate 309, and its purpose is to facilitate the rotation of the rotating plate 309. When the rotating plate 309 rotates downward, the two first springs 310 are extended, so that part of the outer surface of the rotating plate 309 rotates to the outside of the L-shaped groove 307, and then the gas in the drainage tube 313 moves to the inside of the negative pressure chamber 302 under the action of the pressure difference, and then drives the gas in the gasification tube 212 and the threaded tube 210 to move to the inside of the negative pressure chamber 302, so as to collect the unused gas in the gasification chamber 201. When the gas collection is completed, the negative pressure chamber 302 is opened. The air pressure in the pressure chamber 302 tends to be parallel to the air pressure in the drainage tube 313. At this time, the two first springs 310 shorten under their own elastic force, thereby driving the rotating plate 309 to rotate to a position where the outer surface completely overlaps with the inner wall of the L-shaped groove 307, thereby achieving the sealing of the negative pressure chamber 302 and electrically connecting the semiconductor cooling plate 306 to the external power supply to generate low temperature. The cold surface of the semiconductor cooling plate 306 faces the inside of the negative pressure chamber 302. The working principle of the semiconductor cooling plate 306 is based on the Peltier effect. Direct current passes through a junction composed of two different semiconductor materials. When the contact points are connected, heat will be absorbed or released at the contact points. This effect will cause one surface to absorb heat and cool down, while the other surface will release heat and heat up. The interior of the negative pressure chamber 302 is cooled down by the semiconductor refrigeration sheet 306, and the air pump 314 is started at the same time. The air pump 314 generates negative pressure by rotating blades. The air pressure inside the air pump 314 is lower than the external air pressure. The external air will be forced to enter the air pump 314. The high pressure inside the air pump 314 is mainly generated by increasing the internal air pressure through gas compression, thereby forming an airflow to suck gas into the external environment, so that the air pump 314 transports gas to the interior of the negative pressure chamber 302 , under the action of air pressure, the piston 316 is driven to move forward, the gas entering the negative pressure chamber 302 is cooled and pressurized, so that it returns to a liquid state again. As the piston 316 continues to move, the liquefied gas moves forward and finally enters the inside of the water outlet pipe 317 set at the bottom of the negative pressure chamber 302, and finally flows back to the inside of the storage tank 206 under the action of its own gravity, thus completing the liquefaction and collection of the gas, preventing the waste of resources, achieving the effect of energy saving, and solving the problem that the water bath vaporizer in the prior art cannot recycle the vaporized liquid and cause waste of resources.

[0033] Embodiment 2: Figure 1-8As shown, an energy-saving water bath vaporizer includes a mounting plate 1, a vaporization assembly 2 is arranged near the front surface of the top of the mounting plate 1, the vaporization assembly 2 includes a vaporization bin 201, an outer surface of the vaporization bin 201 is fixedly connected with a water inlet pipe 202 near the bottom, a delivery pump 203 is arranged near the center of the front surface of the top of the mounting plate 1, an input end of the delivery pump 203 is fixedly connected with a liquid inlet pipe 204, an output end of the delivery pump 203 is fixedly connected with a liquid outlet pipe 205, and the top of the mounting plate 1 is near the front surface. A storage tank 206 is arranged at one edge of the surface, a heating coil 207 is arranged on the inner bottom surface of the gasification bin 201, a temperature sensor 208 is arranged on the outer surface of the gasification bin 201, a mounting rod 209 is fixedly connected to the inner wall of the gasification bin 201, a threaded tube 210 is fixedly arranged on the outer surface of the mounting rod 209, a limiting plate 211 is fixedly arranged near the top of the inner wall of the gasification bin 201, a gasification tube 212 is arranged on the inner wall of the limiting plate 211, and an air outlet pipe is fixedly connected to the outer surface of the gasification tube 212 near the top. 213, an electromagnetic valve 214 is arranged on the outer surface of the air outlet pipe 213, a negative pressure chamber 302 is fixed at the top of the mounting frame 301 near one side edge, a centrifugal pump 303 is arranged at the top of the mounting frame 301 near one side edge, the output end of the centrifugal pump 303 is fixedly connected with a delivery pipe 304, the delivery pipe 304 extends to the inside of the negative pressure chamber 302, a protective component 4 is arranged at the bottom end of the water outlet pipe 317, and the protective component 4 includes a conical tube 401, and the inner wall of the conical tube 401 is near the top A load-bearing rod 402 is fixed thereon, a second spring 403 is arranged at the bottom of the load-bearing rod 402, a moving ball 404 is fixed at the bottom end of the second spring 403, the top end of the second spring 403 is fixedly connected to the bottom of the load-bearing rod 402, the bottom end of the second spring 403 is fixedly connected to the outer surface of the moving ball 404, a compression rod 405 is fixed to the inner wall of the conical tube 401 near the center, the bottom end of the conical tube 401 is fixedly connected to a recovery tube 5, and the bottom end of the recovery tube 5 passes through the interior of the storage tank 206.

[0034] In this embodiment, in the process of pressurizing the negative pressure chamber 302 and in the process of conveying liquid into the storage tank 206, in order to prevent part of the gas or liquid from flowing back, when the liquid moves along the outlet pipe 317 to the inside of the storage tank 206, the moving ball 404 moves downward under the pressure of the liquid, thereby driving the second spring 403 to extend, so that a gap is generated between the outer surface of the moving ball 404 and the inner wall of the conical tube 401, so that the liquid entering the conical tube 401 moves downward along the gap and flows back to the inside of the storage tank 206 through the recovery pipe 5 for recovery. When gas is extracted from the bin 302, the moving ball 404 moves upward under the adsorption of the gas, so that it is tightly attached to the inner wall of the conical tube 401, thereby isolating the storage tank 206 from the negative pressure bin 302. When part of the liquid in the storage tank 206 vaporizes and moves upward, the moving ball 404 is first driven by the gas to move upward, so that the outer surface of the moving ball 404 is in tight contact with the inner wall of the conical tube 401, thereby effectively preventing part of the gas in the storage tank 206 from flowing outward. Through the action of the protective component 4, the liquid gas in the water bath vaporizer is further protected.

[0035] The method of use and working principle of the device: When liquid nitrogen needs to be converted into gas, first connect the external water source delivery equipment with the water inlet pipe 202, and then deliver the external water source to the inside of the gasification bin 201. At the same time, the heating coil 207 is electrically connected to the external power supply to release heat to the outside, heat the water source in the gasification bin 201, and control the temperature of the water source in the gasification bin 201 through the temperature sensor 208. Then start the delivery pump 203 to drive the liquid inlet pipe 204 to extract liquid nitrogen from the storage tank 206. The liquid nitrogen enters the interior of the threaded pipe 210 through the liquid outlet pipe 205. The spiral shape of the threaded pipe 210 increases the contact area between the liquid nitrogen and the hot water in the gasification bin 201, so that the liquid nitrogen is heated and gasified. And move upward into the interior of the gasification pipe 212, then connect the gas outlet pipe 213 with the external nitrogen pipeline, and open the solenoid valve 214 at the same time, so that the nitrogen in the gasification pipe 212 can be transported outward for use by the external setting. When the external setting does not need to use nitrogen, first close the solenoid valve 214 and the delivery pump 203, start the centrifugal pump 303, and draw gas into the negative pressure chamber 302 through the delivery pipe 304, so that a negative pressure state is formed in the negative pressure chamber 302, and then electrically connect the electromagnet 312 with the external power supply to generate a magnetic field to adsorb the iron block 311, so that the rotating plate 309 and the inner wall of the L-shaped groove 307 are in a parallel state, and the outer surface of the rotating plate 309 coincides with the inner wall of the L-shaped groove 307, thereby forming a negative pressure state. The interior of the negative pressure chamber 302 is sealed. When the pressure sensor 305 detects that the negative pressure value in the negative pressure chamber 302 reaches the required value, the electromagnet 312 is disconnected from the external power supply, so that the electromagnet 312 no longer adsorbs the iron block 311, so that the rotating plate 309 rotates toward the inside of the negative pressure chamber 302 under the action of the negative pressure. When the rotating plate 309 rotates downward, it drives the two first springs 310 to extend, so that part of the outer surface of the rotating plate 309 rotates to the outside of the L-shaped groove 307, so that the gas in the drainage tube 313 moves toward the inside of the negative pressure chamber 302 under the action of the pressure difference, and then drives the gas in the gasification tube 212 and the threaded tube 210 to move toward the inside of the negative pressure chamber 302, so that the unused gas in the gasification chamber 201 is discharged. The air in the negative pressure chamber 302 is collected. When the gas collection is completed, the air pressure in the negative pressure chamber 302 tends to be parallel to the air pressure in the drainage tube 313. At this time, the two first springs 310 are shortened under the action of their own elastic force, thereby driving the rotating plate 309 to rotate to a position where the outer surface completely overlaps with the inner wall of the L-shaped groove 307, thereby achieving the sealing of the negative pressure chamber 302 and electrically connecting the semiconductor refrigeration plate 306 to an external power source to generate a low temperature. The interior of the negative pressure chamber 302 is cooled by the semiconductor refrigeration plate 306, and the air pump 314 is started at the same time, so that the air pump 314 transports gas to the interior of the negative pressure chamber 302. The piston 316 is driven forward by the action of the air pressure, and the gas entering the negative pressure chamber 302 is cooled and pressurized, so that it returns to a liquid state again.As the piston 316 continues to move, the liquefied gas moves forward and finally enters the inside of the water outlet pipe 317 set at the bottom of the negative pressure chamber 302, and finally flows back to the inside of the storage tank 206 under the action of its own gravity, completing the liquefaction and collection of the gas. In the process of pressurizing the negative pressure chamber 302 and in the process of transporting liquid to the storage tank 206, in order to prevent part of the gas or liquid from flowing back, when the liquid moves along the water outlet pipe 317 to the inside of the storage tank 206, the moving ball 404 is moved downward by the pressure of the liquid, thereby driving the second spring 403 to extend, so that the outer surface of the moving ball 404 and the inner wall of the conical tube 401 are connected. A gap is created, so that the liquid entering the conical tube 401 moves downward along the gap and flows back to the storage tank 206 through the recovery pipe 5 for recovery. When it is necessary to extract gas from the negative pressure chamber 302, the moving ball 404 moves upward under the adsorption of the gas, so that it is tightly attached to the inner wall of the conical tube 401, thereby isolating the storage tank 206 from the negative pressure chamber 302. When part of the liquid in the storage tank 206 vaporizes and moves upward, the moving ball 404 is first driven by the gas to move upward, so that the outer surface of the moving ball 404 is tightly in contact with the inner wall of the conical tube 401, preventing part of the gas in the storage tank 206 from flowing outward.
