[0002] In order to reduce energy consumption and lower costs in chemical production, in order to replace the "hydrogen production by water electrolysis" process known as the "electricity guzzler", advanced methanol vapor reforming and pressure swing adsorption technology are used to produce pure hydrogen and CO2-rich mixed gas. After further post-processing, hydrogen and carbon dioxide can be obtained at the same time. Heaters are used in the hydrogen production process.

[0003] However, the heaters currently on the market, when mixing and heating raw materials, produce gases that increase the pressure inside the container.

[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] As attached Figure 1-4 As shown, the utility model provides a mixed heater for producing hydrogen by methanol-water reforming, comprising:

[0029] A partition plate 31 is fixedly installed at the bottom of the inner cavity of the heating box 3, and a heating wire 32 is installed on the bottom surface of the partition plate 31; a pressure relief component is also fixedly installed on the top of the heating box 3.

[0030] The filtered water tank 2 includes a tank body and a tank cover 21; a through hole is opened in the center of the tank cover 21, one end of the water pipe 4 extends into the through hole, and the water pipe 4 is connected to the water pump 6; the filter assembly is fixedly installed on the bottom surface of the tank cover 21; the water inlet pipe 5 is installed on the top side of the tank cover 21.

[0031] The filter assembly includes an outer cylinder 22 and an inner cylinder 23; the inner wall of the outer cylinder 22 is fitted with the inner cylinder 23; the top ends of the outer cylinder 22 and the inner cylinder 23 are vertical, and the bottom ends are inclined toward the bottom end of the inner wall of the box body; the top of the outer cylinder 22 is fixedly installed with the outer periphery of the bottom surface of a fixing seat 24; the fixing seat 24 is embedded in an annular groove 25 opened on the bottom surface of the box cover 21; the inner periphery of the bottom surface of the fixing seat 24 is also formed with an annular clamping protrusion 26; the annular clamping protrusion 26 is formed with a contact ring 27 in the middle of one side wall facing the inner wall of the outer cylinder 22; the inner cylinder 23 is placed between the inner wall of the outer cylinder 22 and the outer side wall of the annular clamping protrusion 26, and the inner wall of the inner cylinder 23 is in contact with the contact ring 27.

[0032] In an embodiment of the present invention, the outer cylinder 22 , the fixing seat 24 and the annular locking protrusion 26 are an integrated structure, and the inner cylinder 23 is positioned by an abutment ring 27 between the outer cylinder 22 and the annular locking protrusion 26 .

[0033] When the raw materials to be heated enter the box through the water inlet pipe 5, they are filtered through the outer cylinder 22 and the inner cylinder 23 and fall to the bottom of the box. The raw materials to be heated are transported to the water pipe 4 by the water pump 6.

[0034] The annular groove 25 is formed upward along the bottom surface of the box cover 21 with the through hole as the center.

[0035] The outer cylinder 22 and the inner cylinder 23 are both provided with filter holes, and the filter holes provided on the outer cylinder 22 have a smaller diameter than the filter holes provided on the inner cylinder 23 .

[0036] The pressure relief assembly includes a hollow pressure relief body 33; a plurality of annular pressure relief grooves 34 are evenly spaced in the middle of the side wall of the pressure relief body 33; an opening 35 is formed at the bottom end of the pressure relief body 33; the opening 35 is a trumpet-shaped structure; a sphere 36 is arranged in the opening 35; an annular gasket 37 is fixedly installed on the bottom surface of the opening 35; a receiving opening is opened in the middle of the annular gasket 37, and the bottom end of the sphere 36 is placed in the receiving opening.

[0038] The sphere 36 is hollow inside.

[0039] In one embodiment of the utility model, when the temperature inside the heating box 3 increases, the internal pressure increases. When the pressure reaches a certain threshold, the gas squeezes the sphere 36 on the annular cushion 37. In a normal state, the sphere 36 fits tightly with the inside of the opening 35 without any squeezing. The pressure relief body 33 is isolated from the inside of the heating box 3.

[0040] Furthermore, when the gas pressure is too high, the sphere will squeeze the inner wall of the opening 35 upward, and the top of the sphere 36 will abut against the horizontal baffle 38. A connecting channel is also provided on the opening 35, and the connecting channel is used to connect the bottom end of the opening 35 and the middle of the pressure relief body 33; the high-pressure gas in the heating box 3 enters the opening through the gap between the sphere 36 and the accommodating port, flows to the horizontal baffle 38 through the connecting channel, and then escapes from the annular pressure relief groove 34 to achieve pressure relief.

[0043] In one embodiment of the utility model, when the heater is used, raw materials to be heated are added to the interior of the filtered water tank 2 through the water inlet pipe 5, and the water pump 6 is controlled to work. The raw materials are pumped into the interior of the heating box 3 through the water pump 6, and then the water pump 6 is controlled to stop working. Then, the heating wire 32 is controlled to heat the raw materials in the heating box 3. When the liquid in the heating box 3 is heated, the temperature inside the heating box 3 increases, thereby causing the internal pressure to increase. When the pressure reaches a certain threshold, the spherical body 36 is lifted up and moves upward, and then the gap between the annular cushion layer 37 and the spherical body 36 opens, and the hot air in the heating box 3 escapes from the annular pressure relief groove 34 through the horizontal baffle 38, thereby achieving the effect of relieving pressure on it.

[0044] In one embodiment of the present utility model, the bottom of the heating box 3 is also connected to an air outlet pipe.

[0045] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
