[0019] like Figure 1-5As shown, this utility model provides a technical solution: a three-phase separation device for supercritical methanol reaction products, including a separation tank 1, a discharge pipe 2 connected to the bottom of the separation tank 1, a feed pipe 4 connected to the top of the separation tank 1, and a connecting assembly 3 installed inside the separation tank 1. The connecting assembly 3 includes a separation mechanism 31 for solid-liquid separation and gas phase demisting, and an adjustment mechanism 32 for uniform distribution of reaction products. A valve is provided at one end of the discharge pipe 2 near the separation tank 1. The separation mechanism 31 includes an installation groove opened inside the separation tank 1, an installation frame 311 inserted into the installation groove, a filter plate 313 fixedly connected inside the installation frame 311, a coolant tank 319 fixedly installed at the top of the separation tank 1, a spiral tube 3110 penetrating inside the coolant tank 319, and a circulation connecting pipe 3111 connected to the left side of the coolant tank 319.

[0020] In this embodiment, the upper part of the mounting frame 311 is provided with a slot 312; the interior of the separation box 1 is provided with a movable slot 315, the inner wall of the movable slot 315 is slidably connected with a movable block 316, and the bottom of the movable block 316 is fixedly connected with a sloped locking block 317. Through the cooperation of the mounting frame 311, slot 312, filter plate 313, sealing ring 314, movable slot 315, movable block 316, sloped locking block 317, spring 318, coolant tank 319, spiral tube 3110, and circulation connecting pipe 3111, the liquid droplets in the gas phase can be condensed, thereby improving the separation effect and facilitating manual disassembly of the mounting frame 311, making it easier to manually remove the collected solid material and clean the filter plate 313, thus facilitating subsequent use.

[0021] Furthermore, the inclined block 317 is movably inserted through the movable groove 315 and engages with the groove 312; a spring 318 is fixedly connected to the inner wall of the movable groove 315, and one end of the spring 318 is fixedly connected to the movable block 316; a movable hole is provided on the outer side of the inner wall of the movable groove 315, and a pull rod is slidably connected to the inner wall of the movable hole, and the pull rod is fixedly connected to the outer side of the movable block 316.

[0022] Furthermore, a sealing ring 314 is fixedly connected to the inner wall of the separation box 1, and the sealing ring 314 is set in the gap between the mounting groove and the mounting frame 311.

[0024] When in use, the device separates solids and liquids through the filter plate 313, and the gas can be discharged outward through the spiral tube 3110. At the same time, the coolant can be circulated through the coolant tank 319 through the circulation connecting pipe 3111, which can cool the spiral tube 3110 and condense the gas, thereby improving the gas-liquid separation effect.

At the same time, the filter plate 313 can be cleaned to prevent the filter holes of the filter plate 313 from becoming clogged and affecting subsequent use. Example 2

[0025] Based on Example 1, a preferred embodiment of the three-phase separation device for supercritical methanol reaction products provided by this invention is as follows: Figures 1 to 5 As shown: The adjustment mechanism 32 includes a motor 321 fixedly installed on the right side of the separation box 1 via a support, a lead screw 322 fixedly connected to the output end of the motor 321, a mounting block 323 threadedly connected to the outer wall of the lead screw 322, a drain plate 324 fixedly installed at the bottom of the mounting block 323, a liquid outlet head 325 communicating with the bottom of the drain plate 324, a slide rod 326 fixedly connected to the inner wall of the separation box 1, a connecting block 327 slidably connected to the outer wall of the slide rod 326, and a connecting pipe 328 communicating with the upper part of the drain plate 324.

[0028] Furthermore, the bottom of the connecting block 327 is fixedly connected to the top of the drain plate 324 to limit the movement direction of the drain plate 324.

[0029] In use, the supercritical methanol reaction products can be fed into the drain plate 324 through the cooperation of the feed pipe 4 and the connecting pipe 328. Then, the material can be output to the upper part of the filter plate 313 through the liquid outlet 325, thus performing solid-liquid separation.
