Description

Technical Field

[0001] The invention relates to the technical field of vaporizers, and in particular to a vaporizer equipped with a steam pipeline. Background Art

[0002] The air bath vaporizer uses the flow of air to heat the cryogenic liquid in the air bath vaporizer, thereby converting the liquid into gas. The cryogenic medium is introduced into the low temperature storage tank and enters the air bath vaporizer for heating and vaporization. Since the initial temperature of the liquid medium reaches minus 185.9℃, and due to the presence of moisture in the air on the heat exchange fins and the surface of the inlet tube, the cryogenic medium absorbs heat from the atmosphere in this tube, and a thick layer of ice will condense, reducing the heating and vaporization effect. Summary of the invention

[0003] The object of the present invention is to provide a vaporizer equipped with a steam pipe to solve the problem proposed in the above background technology that due to the presence of moisture in the air, the low-temperature medium in the heat exchange fins and the inlet tube surface absorbs heat from the atmosphere and condenses a thick layer of ice, thereby reducing the heating and vaporization effect.

[0004] To achieve the above-mentioned purpose, the present invention provides a vaporizer equipped with a steam pipeline, comprising a steam pipeline, one end of which is connected to a steam delivery pipe, the other end of which is connected to a vertical main pipe, the side of which is connected to a plurality of branch pipes, the outer side of which is connected to an annular air outlet pipe, the annular air outlet pipe is located on the outer side of the vaporizer, the inner outer wall of the annular air outlet pipe is provided with a plurality of steam outlets, the branch pipe is provided with a branch pipe valve, and the steam pipeline is provided with a main valve.

[0005] Preferably, the vaporizer comprises a heat exchange tube, one end of the heat exchange tube is connected to a liquid inlet pipe, the other end of the heat exchange tube is connected to an air outlet pipe, and a plurality of heat exchange fins are installed on the outer wall of the heat exchange tube.

[0006] Preferably, a support foot is installed at the bottom of the heat exchange tube.

[0007] Preferably, the annular air outlet pipes are arranged at equal intervals from top to bottom.

[0008] Preferably, the steam outlets are arranged in a circular shape with equal intervals.

[0009] Preferably, the heat exchange fins are installed on the outer wall of the heat exchange tube at equal intervals in an annular manner and are arranged perpendicular to the outer wall surface of the heat exchange tube.

[0010] Preferably, the inner diameter of the annular air outlet pipe is larger than the outer width of the vaporizer.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The vaporizer is equipped with a steam pipe, and steam is introduced through the steam pipe arranged therein. The steam generates heat and transfers it to the heat exchange tubes and heat exchange fins, so that the outer surfaces of the heat exchange tubes and heat exchange fins are not frozen, and can always maintain direct contact with the air and normal air intake heat exchange. At the same time, the low-temperature medium in the tube is further heated to improve the heat exchange efficiency. The annular air outlet pipe ensures that the steam is evenly distributed on the outside of the vaporizer, and heat exchange is guaranteed at each part of the heat exchange tubes and heat exchange fins of the vaporizer, ensuring that the outer surfaces of each part are not frozen. When the vaporization volume of the air bath type vaporizer does not meet the use requirements, the air bath type vaporizer is heated with steam to prevent the vaporizer from freezing. While ensuring normal air supply, the vaporizer outlet temperature can be guaranteed to the greatest extent. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In this embodiment, the vaporizer includes a heat exchange tube 6, one end of the heat exchange tube 6 is connected to a liquid inlet pipe 61 for the entry of low-temperature liquid, the other end of the heat exchange tube 6 is connected to an outlet pipe 62 for the discharge of gas, and the outer wall of the heat exchange tube 6 is installed with a plurality of heat exchange fins 63 for heat exchange between external air and the liquid in the heat exchange tube 6.

[0021] Specifically, a support leg 64 is installed at the bottom of the heat exchange tube 6 to support the bottom of the heat exchange tube 6 .

[0022] Furthermore, the annular air outlet pipes 5 are arranged at equal intervals from top to bottom to ensure uniform heat exchange.

[0023] Furthermore, the steam outlets 51 are arranged in a ring shape with equal intervals, so that the steam can be discharged evenly.
