Description

Technical Field

[0001] The utility model relates to the technical field of water-gas, in particular to a coal processing water-gas conveying device with good sealing performance. Background Art

[0002] Water gas is a low-calorific gas primarily composed of hydrogen and carbon monoxide. It is toxic and primarily used as a raw material for synthetic ammonia and synthetic liquid fuels. It also contains trace amounts of CO, HC, and NOx. When compressed or liquefied, water gas produces a gas similar to hydrogen, but without the need for CO removal. This allows for lower investment and is used industrially as a fuel and chemical feedstock.

[0003] Water gas is produced by the reaction between water vapor and hot anthracite or coke. Therefore, in the production process of water gas, it is necessary to pass through a high-temperature burning coal layer to produce water gas. However, the coal particles inside the traditional coal reactor have different diameters, which will affect the coal combustion efficiency to a certain extent and cause waste of coal resources. Therefore, there are certain limitations.

[0004] For this reason, we urgently need to provide a coal processing water gas conveying device with good sealing performance. Utility Model Content

The right end of the transmission belt is rotatably connected to the rear end of the outer surface of the driving shaft, and the driven shaft is rotatably connected to the left end of the transmission belt.

The coal is crushed by the staggered rotating crushing blades and the side wall knife groups, which is more conducive to its full combustion and the production of water gas.

The feed pipe is fixedly connected to the top center of the crushing box, the delivery pipe is fixedly connected to the bottom center of the crushing box, and the one-way valve is fixedly installed on the outer surface of the delivery pipe. The one-way valve is used to control the delivery amount and timing of coal powder.

[0012] A further improvement is that air holes are evenly opened through the upper surface of the combustion plate, and the height of the water vapor gas pipe is lower than the height of the combustion plate inside the reactor, so that the water vapor inside the water vapor gas pipe can pass through the coal layer burning on the combustion plate, thereby producing water gas.

[0013] A further improvement is that the outer surfaces of the air inlet pipe, steam gas pipe and water gas output pipe are also respectively installed with one-way valves. The setting of the one-way valve can prevent a large amount of pressure inside the reactor from leaking out, thereby creating a suitable water gas production environment.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

[0024] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0025] Embodiment 1 is a coal processing water-gas conveying device with good sealing performance, comprising a reactor 1 , wherein a processing device is arranged inside the reactor 1 .

[0026] The processing device includes an air inlet pipe 401, a steam gas delivery pipe 402, a water gas output pipe 403, a combustion plate 404, and a pressure gauge 405. The air inlet pipe 401 is fixedly connected to the upper left outer surface of the reactor 1, the steam gas delivery pipe 402 is fixedly connected to the lower left outer surface of the reactor 1, the water gas output pipe 403 is fixedly connected to the upper right outer surface of the reactor 1, the combustion plate 404 is fixedly connected to the lower interior of the reactor 1, and the pressure gauge 405 is fixedly installed at the front left side of the upper surface of the reactor 1. The pressure inside the reactor 1 is monitored by the pressure gauge 405, which is safer and more stable.

[0027] The upper surface of the combustion plate 404 is evenly penetrated with air holes, and the height of the steam gas pipe 402 is lower than the height of the combustion plate 404 inside the reactor 1, so that the water vapor inside the steam gas pipe 402 can pass through the coal layer burning on the combustion plate 404, thereby producing water gas.

[0028] One-way valves 309 are installed on the outer surfaces of the air inlet pipe 401, the steam delivery pipe 402, and the water-gas output pipe 403. These prevent the pressure inside the reactor 1 from escaping, thereby creating a suitable environment for water-gas production. Support legs 5 are fixedly attached to the four corners of the bottom surface of the reactor 1, ensuring stable operation of the device.

[0029] During use, first place the coal on the combustion plate 404 inside the reactor 1, then ignite the coal, monitor the pressure inside the reactor 1 through the pressure gauge 405, and then transport air to the inside of the reactor 1 through the air inlet pipe 401 to ensure the normal combustion of the coal inside the reactor 1, and then transport water vapor to the inside of the reactor 1 through the water vapor pipe 402, and pass through the burning coal layer through the air holes on the combustion plate 404, thereby generating a reaction and producing water gas, and then transport the water gas through the water gas output pipe 403. One-way valves 309 are respectively installed on the outer surfaces of the air inlet pipe 401, the water vapor pipe 402 and the water gas output pipe 403, which can prevent a large amount of pressure inside the reactor 1 from leaking out, thereby creating a suitable water gas production environment.

[0030] Example 2. Based on Example 1, the top of the reactor 1 is fixedly connected to a crushing box 2 through support legs 5. A crushing device is provided inside the crushing box 2. The crushing device includes a driving mechanism, a crushing mechanism and a feeding mechanism. The driving mechanism is provided on the back of the crushing box 2, the crushing mechanism is provided above the driving mechanism, and the feeding mechanism is provided at the bottom of the crushing box 2.

[0031] The driving mechanism includes a crushing motor 301, a driving shaft 302, a transmission belt 303, and a driven shaft 304. The crushing motor 301 is installed on the right side of the back of the crushing box 2. The rear end of the driving shaft 302 is connected to the output end of the crushing motor 301, and its front end passes through the crushing box 2 and is rotatably connected to the inner wall of the crushing box 2. The right end of the transmission belt 303 is rotatably connected to the rear end of the outer surface of the driving shaft 302, and the driven shaft 304 is rotatably connected to the left end of the transmission belt 303.

[0032] The crushing mechanism includes a crushing blade 305 and a side wall knife group 306. The two crushing blades 305 are fixedly connected to the outer surfaces of the driving shaft 302 and the driven shaft 304 respectively, and the two side wall knife groups 306 are fixedly connected to the left and right inner walls of the crushing box 2 respectively. The coal is crushed by the staggered rotating crushing blades 305 and the side wall knife group 306, which is more conducive to its full combustion and the production of water gas.

[0033] The feeding mechanism includes a feed pipe 307, a feed pipe 308, and a one-way valve 309. The feed pipe 307 is fixedly connected to the top center of the crushing box 2, the feed pipe 308 is fixedly connected to the bottom center of the crushing box 2, and the one-way valve 309 is fixedly installed on the outer surface of the feed pipe 308. The one-way valve 309 is used to control the coal powder delivery amount and delivery timing.

[0034] Before producing water gas, the coal blocks are poured into the interior of the crushing box 2 through the feed pipe 307, and then the crushing motor 301 is started to drive the driving shaft 302 to rotate. The rotation of the driving shaft 302 drives the transmission belt 303 on it to rotate, thereby driving the driven shaft 304 to rotate, so that the crushing blades 305 on the outer surfaces of the driving shaft 302 and the driven shaft 304 rotate, and cooperate with the side wall knife group 306 on the inner wall of the crushing box 2 to crush the coal blocks into coal powder, which is more conducive to its combustion and the production of water gas.
