[0002] Methanol is an organic compound with the chemical formula CH3OH. It is also the simplest saturated monohydric alcohol. It is also called hydroxymethane, wood alcohol or wood spirit. It used to be mainly produced by extraction from wood vinegar. Modern methanol is directly produced from the catalytic action of carbon monoxide, carbon dioxide and hydrogen. However, when existing equipment is used to produce methanol, an essential step is to dry out the moisture in the coal gas. However, after using adsorbents to treat the moisture in the coal gas, because the installation and disassembly of the adsorbents are more troublesome, the adsorbents may not be replaced in time and are difficult to replace, resulting in a significant decrease in production efficiency and a decrease in the quality of the final product.

[0022] The utility model is further described below in conjunction with embodiments.

[0023] See also Figure 1-Figure 5 The drying component 2 includes a connecting plate 21 fixedly mounted on one side of the drying barrel 1, a replacement hole 27 provided on one side of the connecting plate 21, a hole door 28 rotatably connected to one side of the replacement hole 27, a drying chamber 23 provided on the lower surface of the connecting plate 21, a fixed plate 25 arranged inside the drying chamber 23, and a drying plate 26 movably mounted on the lower surface of the fixed plate 25, and the replacement hole 27 is communicated with the drying chamber 23, and the fixing plate 25 is movably connected to the drying plate 26, and the drying plate 26 can be directly pulled out through the replacement hole 27 to facilitate replacement of the things inside the drying plate 26 for drying coal gas.

[0024] The drying component 2 also includes a motor 22 fixedly mounted on the upper surface of the connecting plate 21, and a driving rod 24 movably mounted on the lower surface of the motor 22, and one side of the driving rod 24 passes through the connecting plate 21 and is connected to the output end of the motor 22, and one side of the fixing plate 25 is fixedly connected to the driving rod 24. The saturated drying plate 26 can be replaced by rotating the driving rod 24, and a new drying plate 26 can continue to dry the coal gas.

[0025] A rectangular groove 251 is formed on the lower surface of the fixing plate 25, a slide groove 252 is formed on the upper surface of the rectangular groove 251, and the slide groove 252 is connected to the rectangular groove 251. A limit block 253 is fixedly installed at the bottom of the slide groove 252. The limit block 253 can prevent the drying plate 26 from moving due to inertia when rotating inside the drying chamber 23.

[0026] A flap 261 is rotatably connected to the upper surface of the drying plate 26, a handle 262 is fixedly installed on the outer surface of the flap 261, an adsorbent 263 is arranged between the drying plate 26 and the flap 261, air holes 265 are penetrated by the flap 261 and the drying plate 26, a translation assembly 264 for moving the entire drying plate 26 is fixedly installed on one side of the drying plate 26, the internal adsorbent 263 can be replaced by opening the flap 261, and the adsorbent 263 can better absorb moisture in the coal gas through the air holes 265.

[0027] The translation assembly 264 includes an L-shaped plate 2641 fixedly installed on one side of the drying plate 26, fixed rods 2642 fixedly installed on both sides of the L-shaped plate 2641, and rollers 2643 sleeved on the outer surface of the fixed rods 2642, and the rollers 2643 are movably connected to the slide grooves 252. The drying plate 26 can be separated from and merged with the fixed plate 25 at will through the rollers 2643, and the drying plate 26 can be kept on the lower surface of the fixed plate 25 through the fixed rods 2642.

[0028] An air inlet pipe 11 is fixedly installed on one side of the drying barrel 1, an air outlet pipe 12 is fixedly installed on the other side of the drying barrel 1, a support seat 13 is fixedly installed on the outer surface of the drying barrel 1, a drying port 14 is opened on the upper surface of the drying barrel 1, and the drying port 14 corresponds to the drying plate 26. The coal gas can enter the interior of the drying barrel 1 through the air inlet pipe 11 and the air outlet pipe 12 and then be discharged, and the cooperation of the drying port 14 and the drying plate 26 can absorb moisture in the coal gas.

[0029] Specifically, when it is necessary to deal with the moisture in the coal gas, first open the hole door 28, then start the motor 22 to let the driving rod 24 move the drying plate 26 and the fixed plate 25 to the position of the replacement hole 27, and then pull the handle 262. Because the translation component 264 on one side of the drying plate 26 is slidably connected with the slide groove 252 inside the fixed plate 25, the drying plate 26 can be pulled out by pulling the handle 262. However, the rectangular groove 251 and the slide groove 252 are located in the center of the fixed plate 25, so there is no need to worry that the drying plate 26 will be pulled out as a whole. After the drying plate 26 is pulled out, the flap 261 can be opened to put the adsorbent 263 into the drying plate 26, and then the flap 261 can be closed to push the drying plate 26 back into the drying chamber 23. At this time, the motor 22 can be started again to allow the next drying plate 26 to move to the replacement hole 27. , because there is a limiting block 253 inside the slide groove 252 and the slide groove 252 is higher than the roller 2643, the drying plate 26 will not be thrown out due to inertia when it rotates. After the remaining adsorbent 263 is installed according to this method, the hole door 28 can be closed to allow the gas to enter the drying barrel 1 through the air inlet pipe 11 for drying. If an adsorbent 263 is saturated, the motor 22 can be started to let the driving rod 24 bring the saturated adsorbent 263 to the position of the replacement hole 27 for replacement. At this time, due to the rotation of the driving rod 24, the new adsorbent 263 will come to the position of the drying port 14 to continue working. Finally, when the moisture inside the gas is completely processed, the gas outlet pipe 12 is opened to discharge the gas, so that the adsorbent 263 can be easily replaced to greatly improve the work efficiency.
