Description

Technical Field

[0001] This utility model relates to the field of methanol vaporizer technology, specifically to a methanol vaporizer with internal fins. Background Technology

[0002] A methanol vaporizer works by heating liquid methanol, causing it to evaporate and produce methanol vapor, which is then mixed with air to form a combustible gas. Common heating methods include combustion heating and electric heating. It is widely used in industry, energy, and environmental protection fields.

[0003] The heat dissipation design of the methanol vaporizer is crucial for the overall efficient operation and safety of the equipment. In the existing technology, there are two common ways to dissipate heat from the vaporizer body in methanol vaporization operations. One is finned heat dissipation, which involves setting heat dissipation aluminum fins on the surface of the heating tube to increase the heat exchange area and facilitate rapid heat dissipation of the heating components after operation. However, this method is prone to heat loss during operation, reducing vaporization efficiency. The other method is heat exchange circulation, which involves introducing condensate and carrying away heat through the circulation of condensate. However, this method requires separate coiling of condenser tubes inside the vaporizer body, which is structurally complex, troublesome to maintain, and has room for technical improvement. Utility Model Content

[0004] This invention aims to solve the aforementioned technical problem of limitations in the heat exchange structure of the vessel during methanol vaporization operations, and provides a methanol vaporizer with internal fins.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a methanol vaporizer with internal fins, comprising a body, an inlet pipe provided at the lower end of one side of the body, and an outlet pipe and a catalytic pipe provided at the upper end of the body; a liquid inlet pipe is provided near the upper end of one side of the body, and a liquid outlet pipe is provided near the lower end; further comprising:

[0006] Inner sleeve; the inner sleeve is provided with fixing rings on the outer sides of both the upper and lower ends, and the outer sides of the fixing rings are fixedly connected to the inner side of the device body;

[0007] The fins are all annular, and there are multiple fins that are fixed at intervals on the outside of the inner sleeve. The outer surface of each fin is fixed to the inner surface of the vessel. Each fin has a notch, and the notch positions on adjacent fins are different. The end of the liquid inlet pipe extends to the top of the uppermost fin, and the end of the liquid outlet pipe extends to the bottom of the lowermost fin.

[0008] Baffle blocks; multiple blocks are provided and symmetrically arranged between adjacent fins.

[0009] Furthermore, the device is equipped with a thermometer and a pressure gauge.

[0010] Furthermore, the fixing ring and the outer side of the fin are welded to the inner side of the device body.

[0011] Furthermore, the notch angles on adjacent fins differ by a certain degree.

[0012] Furthermore, the fin is provided with several through slots on both sides of the notch, and the inner corners of the through slots are all rounded.

[0013] Furthermore, the cross-section of each of the baffles is triangular, and each baffle is made of aluminum.

[0014] The advantages of this utility model compared with the prior art are as follows:

[0015] It is equipped with several annular fins, which form a through multi-layer channel. With the help of condensate, heat can be transferred from the heating components inside the inner sleeve to the outside. During this process, the flow of condensate is disrupted by multiple turbulence blocks to increase the circulation time and improve the heat exchange effect.

[0016] In methanol vaporization, heat exchange can be avoided by not introducing condensate. Depending on actual needs, insulation medium and high-temperature liquid can also be introduced to reduce heat loss and ensure vaporization efficiency. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] Example 1, in conjunction with Appendix Figure 1 A methanol vaporizer with internal fins includes a body 1, an inlet pipe 2 at the lower end of one side of the body 1, an outlet pipe 3 and a catalytic pipe 4 at the upper end of the body 1; a thermometer 9 and a pressure gauge 10 are provided on the body 1; the inlet pipe 2 is used to introduce liquid methanol, and the outlet pipe 3 is used to export vapor components.

[0024] Combined with appendix Figure 1 The container body 1 has an inlet pipe 5 near the upper end and an outlet pipe 6 near the lower end on one side. The inlet pipe 5 and the outlet pipe 6 are used to introduce condensate during heat exchange. When necessary, heat-insulating medium or high-temperature liquid can also be introduced during operation to promote the reaction and reduce heat loss.

[0025] Combined with appendix Figure 2 , 3 4. It also includes an inner sleeve 7; the upper and lower outer sides of the inner sleeve 7 are provided with fixing rings 8, and the outer sides of the fixing rings 8 are fixed to the inner side of the body 1; so that a cavity is formed between the inner sleeve 7 and the body 1, the cavity is used for heat preservation during operation and heat exchange after operation.

[0026] Based on the above structure, it also includes fins 11; all of which are annular, and multiple fins are provided and fixed at intervals on the outside of the inner sleeve 7. The outer side of the fins 11 is fixed to the inner side of the body 1. Specifically, the fixing ring 8 and the outer side of the fins 11 are welded to the inner side of the body 1, resulting in high structural strength and good impact resistance.

[0027] Each fin 11 has a notch 12, and the angles of the notches 12 on adjacent fins 11 differ by 180 degrees, so that the inner sleeve 7, the fixing ring 8, the multiple fins 11 and the corresponding notches 12 together form a multi-layered S-shaped flow channel.

[0028] In addition, several through slots 13 are provided on the fins 11 and on both sides of the notch 12. The inner corners of the through slots 13 are all rounded. The through slots 13 can divert some of the medium and also play a role in turbulence, increasing the contact time between the medium and heat.

[0029] Based on the above structure, the end of the liquid inlet pipe 5 extends above the uppermost fin 11, and the end of the liquid outlet pipe 6 extends below the lowermost fin 11. The liquid outlet pipe 6 is connected to an external pump set to realize the circulation of the medium.

[0030] It also includes baffle blocks 14, which are provided in multiples and symmetrically arranged between adjacent fins 11; the cross-section of each baffle block 14 is triangular and the baffle blocks are all made of aluminum, so the baffle blocks 14 have good thermal conductivity and can also play a heat exchange role; the symmetrical arrangement of the baffle blocks 14 can increase the impact and resistance of the medium flow, slow down the flow speed, and make full contact with heat, resulting in good heat exchange effect.
