Description

Technical Field

[0001] The utility model relates to the technical field of vaporizers, in particular to an anti-icing high-efficiency water bath vaporizer. Background Art

[0002] A vaporizer is a device used to heat liquid gas into gas. Simply put, cold liquid gas becomes gaseous gas after passing through the vaporizer. The heating can be indirect (steam heating vaporizer, hot water bath vaporizer, natural ventilation air bath vaporizer, forced ventilation vaporizer, electric heating vaporizer, solid heat conduction vaporizer or heat transfer fluid) or direct (hot gas or submerged combustion).

[0003] The steam inlet of the steam-heated vaporizer in the prior art is located at the bottom of the vaporizer, and the flow of the hot water in the vaporizer is powered only by the steam entering. Therefore, the flow rate of the hot water in the vaporizer is slow, resulting in a low water temperature at the top of the vaporizer, which affects the heat exchange efficiency.

[0004] In view of this, there is an urgent need for an anti-icing and efficient water bath vaporizer. Summary of the invention

[0005] In view of the problems existing in the prior art, the utility model solves the problems with the following technical structure.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An anti-icing high-efficiency water bath vaporizer comprises: a shell, a heat exchange tube, a water pumping device, a steam injection pipe, a liquid inlet pipe and an air outlet pipe, the inner cavity of the shell is a gasification chamber, the heat exchange tube is arranged in the gasification chamber, the steam injection pipe and the liquid inlet pipe are both arranged at the bottom of the gasification chamber, the air outlet pipe is arranged at the top of the gasification chamber, the top end of the heat exchange tube is connected to the air outlet pipe, the bottom end of the heat exchange tube is connected to the liquid inlet pipe, the water inlet end of the water pumping device is connected to the top of the gasification chamber, the water outlet end of the water pumping device is connected to the bottom of the gasification chamber, and the water pumping rate of the water pumping device is greater than the conveying rate of steam and water into the gasification chamber by the steam injection pipe.

[0008] A further feature is that

[0009] The gasification chamber is provided with an annular tube above the heat exchange tube, the annular tube is connected to the water inlet end of the pumping device, and a plurality of water inlet holes are provided on the annular tube.

[0010] The steam injection pipe is arranged below the liquid inlet pipe.

[0011] The steam injection pipe is provided with a plurality of injection heads facing the liquid inlet pipe.

[0012] A cylinder is arranged in the gasification chamber, and the bottom of the cylinder is arranged in a cone shape.

[0013] The heat exchange tube is arranged on the outside of the cylinder, and the heat exchange tube is composed of a plurality of spiral hollow tubes.

[0014] The steam injection pipe is annular, and the steam inlet end of the steam injection pipe extends to the outside of the shell.

[0015] The liquid inlet pipe is annular, and the liquid inlet port of the liquid inlet pipe extends to the outside of the shell.

[0016] An annular connecting pipe is arranged at the bottom of the air outlet pipe, the annular connecting pipe is connected with a plurality of hollow pipes, and the top end of the air outlet pipe extends to the outside of the shell.

[0017] A mounting frame is arranged in the shell, and a plurality of the hollow tubes are arranged on the mounting frame.

[0018] The above structure of the utility model can achieve the following beneficial effects:

[0019] When in use, low-temperature liquid enters from the liquid inlet pipe and then enters the heat exchange tube. Hot steam enters the bottom of the vaporization chamber from the steam injection pipe, heats the hot water, and provides heat for the heat exchange of the low-temperature medium in the heat exchange tube. Finally, the vaporized gas is discharged from the gas outlet pipe. During this process, the pumping device extracts the low-temperature water at the top of the vaporization chamber and transports it to the bottom of the vaporization chamber, thereby increasing the fluidity of the water flow in the vaporization chamber. The pumping rate of the pumping device is greater than the rate at which the steam and water are transported into the vaporization chamber by the steam injection pipe (a drain pipe is provided on the shell to discharge the overflowed hot water), so that a siphon phenomenon occurs in the heat exchange tube part in the vaporization chamber, which further enhances the fluidity of the water in the vaporization chamber, effectively avoids ice formation in the vaporization chamber, and greatly improves the heat exchange efficiency of the heat exchange tube.

[0024] The following is combined with Figure 1 This application is described in further detail.

[0025] Example 1, reference Figure 1 The anti-icing high-efficiency water bath vaporizer shown in the figure comprises: a shell 1 (the shell 1 is sealed and filled with hot water), a heat exchange tube 2, a pumping device 3, a steam injection tube 5, a liquid inlet tube 6 and an air outlet tube 7. The inner cavity of the shell 1 is a vaporization cavity, the heat exchange tube 2 is arranged in the vaporization cavity, the steam injection tube 5 and the liquid inlet tube 6 are both arranged at the bottom of the vaporization cavity, the air outlet tube 7 is arranged at the top of the vaporization cavity, the top end of the heat exchange tube 2 is connected to the air outlet tube 7, the bottom end of the heat exchange tube 2 is connected to the liquid inlet tube 6, the water inlet end of the pumping device 3 is connected to the top of the vaporization cavity, and the water outlet end of the pumping device 3 is connected to the bottom of the vaporization cavity. The pumping rate of the pumping device 3 is greater than the conveying rate of steam and water from the steam injection tube 5 to the vaporization cavity. In this way, when in use, the cryogenic liquid is discharged from the vaporization cavity. The liquid enters through the liquid inlet pipe 6 and then enters the heat exchange tube 2. The hot steam enters the bottom of the vaporization chamber from the steam injection pipe 5, heats the hot water, and provides heat for the heat exchange of the low-temperature medium in the heat exchange tube 2. Finally, the vaporized gas is discharged from the gas outlet pipe 7. During this process, the pumping device 3 extracts the low-temperature water at the top of the vaporization chamber and transports it to the bottom of the vaporization chamber, thereby increasing the fluidity of the water flow in the vaporization chamber. The pumping rate of the pumping device 3 is greater than the transport rate of steam and water into the vaporization chamber by the steam injection pipe 5 (a drain pipe is provided on the shell 1 to discharge the overflowed hot water), so that a siphon phenomenon occurs in the heat exchange tube part in the vaporization chamber, which further enhances the fluidity of the water in the vaporization chamber, effectively avoids ice in the vaporization chamber, and greatly improves the heat exchange efficiency of the heat exchange tube.

[0026] refer to Figure 1As shown, the vaporization chamber is provided with an annular tube 4 above the heat exchange tube 2, and the annular tube 4 is connected to the water inlet end of the pumping device 3. A plurality of water inlet holes are provided on the annular tube 4, so that the hot water at the top of the vaporization chamber is evenly transported to the bottom of the vaporization chamber by the pumping device 3, further improving the fluidity of the hot water.

[0027] refer to Figure 1 As shown, the steam injection pipe 5 is annular, and the steam inlet end of the steam injection pipe 5 extends to the outside of the shell 1. The steam injection pipe 5 is arranged below the liquid inlet pipe 6. The steam injection pipe 5 is provided with a plurality of injection heads 8 facing the liquid inlet pipe 6. A cylinder 9 is provided in the vaporization chamber, and the bottom of the cylinder 9 is set to be conical. The annular steam injection pipe 5 cooperates with the injection head 8 to improve the uniformity of steam input into the vaporization chamber, and the bottom of the cylinder 9 is conical, which has the effect of equal flow. The steam injection pipe 5 is arranged below the liquid inlet pipe 6, and the ejected steam can ensure that the liquid inlet pipe 6 will not freeze due to the entry of low-temperature liquid.

[0028] refer to Figure 1 As shown, the heat exchange tube 2 is arranged on the outside of the cylinder 9, and the heat exchange tube 2 is composed of a plurality of spiral hollow tubes. A mounting frame 11 is arranged in the shell 1, and a plurality of hollow tubes are arranged on the mounting frame 11. The spiral hollow tube can extend the heat exchange path and ensure the heat exchange effect.

[0029] refer to Figure 1 As shown, the liquid inlet pipe 6 is annular, and the liquid inlet port of the liquid inlet pipe 6 extends to the outside of the shell 1. The annular liquid inlet pipe 6 can transport the liquid to multiple hollow tubes.

[0030] refer to Figure 1 As shown, an annular connecting pipe 10 is provided at the bottom of the outlet pipe 7, and the annular connecting pipe 10 is connected to multiple hollow tubes. The top end of the outlet pipe 7 extends to the outside of the shell 1, and the gas output from the multiple hollow tubes is guided to the outlet pipe 7 through the annular connecting pipe 10.

[0031] In summary, when in use, the low-temperature liquid enters from the liquid inlet pipe 6 and then enters the heat exchange tube 2. The hot steam enters the bottom of the vaporization chamber from the steam injection pipe 5, heats the hot water, and provides heat for the heat exchange of the low-temperature medium in the heat exchange tube 2. Finally, the vaporized gas is discharged from the gas outlet pipe 7. During this process, the pumping device 3 extracts the low-temperature water at the top of the vaporization chamber and transports it to the bottom of the vaporization chamber, thereby increasing the fluidity of the water flow in the vaporization chamber. The pumping rate of the pumping device 3 is greater than the rate at which the steam and water are transported into the vaporization chamber by the steam injection pipe 5 (a drain pipe is provided on the shell 1 to discharge the overflowed hot water), so that a siphon phenomenon occurs in the heat exchange tube part in the vaporization chamber, which further enhances the fluidity of the water in the vaporization chamber, effectively avoids ice formation in the vaporization chamber, and greatly improves the heat exchange efficiency of the heat exchange tube.
