Description

Technical Field

[0001] The utility model relates to a cold energy recovery and utilization device, in particular to a water distribution type air-temperature gasifier. Background Art

[0002] Many types of liquids, such as liquefied natural gas (LNG), liquid oxygen, liquid nitrogen, liquid ethane, liquid propane, etc., need to be vaporized before use. The vaporization process releases a large amount of cold energy. If this cold energy is recovered, energy consumption can be reduced and economic benefits can be obtained.

[0003] Air-temperature vaporizer is a device that uses air as the heat source for vaporization and heats the liquid in the tube to vaporize it. It has a simple structure and is easy to use, and is widely used in the field of vaporization. However, the vaporization cooling capacity of traditional air-temperature vaporizers is dissipated into the air, and when the ambient air temperature drops, the vaporization efficiency will quickly decrease.

[0004] CN201921413383.X once disclosed an LNG air-temperature vaporizer facility, including an air-temperature vaporizer, the air-temperature vaporizer having a plurality of central tubes and heat dissipation fins, the lower end of the heat dissipation fins being beveled, the central tubes and the heat dissipation fins being interconnected to form a vertically porous vaporization chamber, a hot air supply device being provided on the top of the air-temperature vaporizer, the hot air supply device being connected to the vaporization chamber of the air-temperature vaporizer through an air supply pipe; condensation water grooves are provided around the bottom of the air-temperature vaporizer. The utility model increases the flow of air on the surface of the air-temperature vaporizer, can improve the efficiency of the vaporizer, solve the problem of frost and ice on the surface of the LNG vaporizer, and increase the condensation efficiency at the same time. However, the effect of improving the vaporization efficiency by increasing the air flow is relatively poor, and the cold energy cannot be recovered, which will cause a waste of cold energy.

[0005] Therefore, how to design an air-temperature vaporizer device that can both improve the gasification efficiency of the device and recover cold energy has become a problem that technical personnel in this field need to consider and solve. Utility Model Content

[0006] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by the present invention is: how to provide a water-distributing air-temperature gasifier which can improve the gasification efficiency of the device, recycle cold energy for utilization, and avoid waste.

[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0008] A water distribution type air-temperature vaporizer includes an air-temperature vaporizer, which has a plurality of vertically arranged vaporization pipelines, and also includes a liquid inlet pipe and an air outlet pipe connected to the vaporization pipelines. It is characterized in that a water distribution tank for containing antifreeze (or water) is also provided at the upper end of the air-temperature vaporizer, and the vaporization pipelines all fall into the lower projection of the water distribution tank. It also includes a water collecting tank arranged at the lower position of the air-temperature vaporizer opposite to the water distribution tank. The gasification pipeline is vertically connected and fixed between the water distribution tank and the water collecting tank. A plurality of water distribution holes located outside the gasification pipeline are downwardly opened on the water distribution tank. A water distribution outlet is provided on one side of the water collecting tank and is connected to a water distribution circulation pipeline. A water distribution circulation pump is installed on the water distribution circulation pipeline. The upper end of the water distribution circulation pipeline is connected to the water distribution inlet of the water collecting tank to form a circulation.

[0009] In this way, during operation, the antifreeze (or water) flows downward from the water distribution tank and flows downward along the outside of the gasification pipe. The gasification pipe uses the flowing antifreeze (or water) as a medium to exchange heat with the air, which can better improve the heat exchange efficiency with the air. At the same time, the antifreeze (or water) itself can further take away part of the cold generated by the gasification pipe during the gasification process, further improving the heat exchange effect, and improving the gasification efficiency and heat exchange rate inside the gasifier.

[0010] Furthermore, the water distribution holes on the water distribution box are arranged along the edge of the gasification pipeline.

[0011] This can better ensure that the antifreeze (or water) flowing downward can flow downward along the edge of the gasification pipe.

[0012] Furthermore, a layer of wetting material is provided on the lower surface of the water distribution tank.

[0013] In this way, it can be better ensured that the antifreeze liquid (or water) flowing downwards can flow downwards along the edge of the gasification pipe, thereby preventing it from dripping directly downwards.

[0014] Furthermore, vertical fins are arranged around the gasification pipeline.

[0015] In this way, the heat exchange efficiency can be better improved.

[0016] Furthermore, a rain shield is provided at the upper end of the water distribution tank, and both the water distribution tank and the water collection tank fall within the horizontal projection range of the rain shield.

[0017] In this way, the disturbing influence of rain can be better avoided.

[0018] Furthermore, a heat exchange outlet is provided on the other side of the water collecting tank, and the heat exchange outlet is connected and fixedly arranged with one end of a heat exchange pipe. A heat exchanger and a heat exchange circulation pump are installed on the heat exchanger. A cooling medium inlet and a cooling medium outlet are provided on the heat exchanger. The other end of the heat exchange pipe is connected and fixedly arranged with a water collecting tank inlet above the water collecting tank to form a circulation.

[0019] In this way, the antifreeze (or water) in the water collecting tank can be further circulated and exchanged with heat through heat exchange pipes and heat exchangers, and the accumulated cold energy can be exchanged and displaced out for utilization, thereby better improving the utilization effect of cold energy and avoiding the waste of cold energy.

[0020] Furthermore, a layer of heat-insulating material is arranged outside the water collecting tank, so as to better avoid the waste of cooling capacity.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: a water distributor is provided on the upper part of the air-temperature gasifier, and a water collecting tank is provided on the lower part. The high-temperature antifreeze (or water) flowing out from the small holes at the bottom of the water distributor and evenly sprayed on the surface of the air-temperature gasifier exchanges heat with the low-temperature liquid substance flowing into the internal pipe of the air-temperature gasifier from the liquid inlet pipe. The low-temperature antifreeze (or water) after the heat exchange flows into and is stored in the water collecting tank or the water collecting pool, so that the gasification cold energy can be stored in the antifreeze (or water) during the gasification process; at the same time, the cold energy accumulated in the antifreeze (or water) can be exchanged through the circulation system where the heat exchanger is located, thereby realizing the recovery and utilization of cold energy.

[0022] In summary, the present invention has the advantages of simple structure, improving the gasification efficiency of the device, recovering cold energy for utilization, and avoiding waste of cold energy. BRIEF DESCRIPTION OF THE DRAWINGS
