Description

Technical Field

[0001] The present invention belongs to the technical field of chemical engineering and relates to a box structure for a methanol-to-hydrogen extraction device. Background Art

[0002] In the prior art, methanol-to-hydrogen is a process in which methanol reacts with water vapor under the action of a catalyst to generate hydrogen and carbon dioxide. During the process of methanol-to-hydrogen production, heat is required to catalyze the reaction. The existing methanol-to-hydrogen extraction device uses boiler wastewater to utilize the residual heat of the boiler water to provide heat. However, the existing boiler wastewater transports heat to the methanol-to-hydrogen extraction device through a simple pipeline structure, resulting in a relatively fast heat dissipation rate and a low utilization efficiency of the waste heat of the boiler wastewater, thereby leading to a poor effect of maintaining a constant temperature inside the box. Summary of the Invention

[0003] In view of the above problems, the object of the present invention is to propose a box structure for a methanol-to-hydrogen extraction device.

[0004] The technical solution of the present invention is as follows: A box structure for a methanol-to-hydrogen extraction device according to the present invention includes a heat preservation box, and the heat preservation box includes a box body. Box door panels are fixedly provided at both the left and right ends of the box body.

[0005] A methanol-to-hydrogen extractor is installed in the heat preservation box. The methanol-to-hydrogen extractor includes a machine body. A feed pipe and a hydrogen outlet pipe are respectively fixedly connected and communicated on the machine body. A wire threading pipe penetrating through one box door panel of the heat preservation box is installed on a side wall of the machine body.

[0006] Furthermore, a hexagonally meshed pipeline that is interconnected is laid on the outer wall of the heat preservation box.

[0007] Furthermore, a pump is connected to one side of the wire threading pipe. A water inlet pipe is fixedly connected and communicated to the upper water outlet of the pump. The other end of the water inlet pipe is fixedly connected and communicated with the hexagonally meshed pipeline.

[0008] Furthermore, a water suction pipe is also fixedly connected and communicated to the water inlet of the pump.

[0009] Furthermore, a temperature and pressure monitoring module is fixedly embedded at the upper end of the other box door panel of the heat preservation box. A temperature display and a pressure display are installed on the temperature and pressure monitoring module. A control panel is installed on the temperature and pressure monitoring module.

[0010] Two working status indicator lights are also installed on the temperature and pressure monitoring module.

[0011] Furthermore, an observation hole is opened at the lower end of the temperature and pressure monitoring module on the box door panel, and a transparent glass plate is fixedly embedded in the observation hole.

[0012] Further, a water outlet pipe communicated with the hexagonal mesh pipeline is fixedly connected to the box door panel on the other side of the incubator, and a first flange is fixedly connected to the end of the water outlet pipe away from the incubator.

[0013] Further, the upper ends of the feed pipe and the hydrogen outlet pipe both extend out of the upper wall of the incubator.

[0014] Further, the hexagonal mesh pipeline is closely attached to the outer wall of the incubator, and part of the pipeline of the hexagonal mesh pipeline is communicated with the inside of the methanol hydrogen production extractor.

[0015] Further, an inner shell of the methanol hydrogen production extractor is also covered inside the incubator, and a heat preservation cover shell is fixedly sleeved outside the inner shell.

[0016] The beneficial effects of the present invention are as follows: By setting the incubator, methanol hydrogen production extractor, threading pipe, hexagonal mesh pipeline, water inlet pipe, water outlet pipe, pump and water extraction pipe, since the hexagonal mesh pipeline covers the incubator, the heat dissipated from the hexagonal mesh pipeline can achieve the heat preservation effect, so that the inside of the box body can be kept at a constant temperature. Moreover, the heat introduced into the methanol hydrogen production extractor through the hexagonal mesh pipeline can provide heat for hydrogen production. Compared with the simple pipeline structure in the prior art, the hexagonal mesh pipeline set in the box body structure of the present invention can improve the utilization efficiency of the waste heat in the boiler wastewater, thereby reducing energy consumption, reducing the cost of methanol hydrogen production, and the special structure of the hexagonal mesh pipeline has good anti-collision and fire prevention effects.

Compared with the simple pipeline structure in the prior art, the hexagonal mesh pipeline 4 provided in this box body structure can improve the utilization efficiency of the waste heat in the boiler wastewater, thereby reducing energy consumption and the cost of methanol hydrogen production. Moreover, the special structure of the hexagonal mesh pipeline 4 has a protective effect when the device is impacted, so as to provide anti-collision protection for the internal methanol hydrogen production extractor 2.

[0031] Furthermore, a temperature and pressure monitoring module 9 is fixedly embedded on the heat insulation box 1. A temperature display meter 10 and a pressure display meter 11 are installed on the temperature and pressure monitoring module 9.
