[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0027] like Figures 1 to 5 As shown, a biomass pyrolysis and gasification synthesis green methanol system includes a gasifier 1, a preparatory furnace 2 arranged on one side of the gasifier 1, a filtering and cleaning mechanism 31 is provided on the gasifier 1, and a crushing and conveying mechanism 32 is provided in the preparatory furnace 2. The filtering and cleaning mechanism 31 includes a support plate 311 fixedly connected to the outer wall of the gasifier 1, and a filter box 313 is fixedly connected to the top of the support plate 311. The outer wall of the filter box 313 is connected with a connecting pipe 312, and the connecting pipe 312 is connected to the top of the gasifier 1 at one end away from the filter box 313. A clamping groove is provided on the top of the inner wall of the filter box 313, and a filter plate 314 is clamped on the inner wall of the clamping groove. A positioning hole 315 is provided on the outer wall of the filter plate 314. A circular hole is provided on the outer wall of the filter box 313, and a positioning rod 316 is slidably connected to the inner wall of the circular hole. The positioning rod 316 is fixedly connected to the connecting plate 317 at one end away from the circular hole. A spring 318 is fixedly connected, and one end of the spring 318 away from the connecting plate 317 is fixedly connected to the outer wall of the filter box 313. A pull rod 319 is fixedly connected to the outer wall of the connecting plate 317. A connecting rod 3110 is fixedly connected to the outer wall of the connecting plate 317. A rotating rod 3111 is rotatably provided on the outer wall of the filter box 313. A connecting chute is provided on the outer wall of the filter box 313. A connecting slide 3112 is slidably provided on the inner wall of the connecting chute. The connecting slide 311 A force block 3113 is fixedly connected to the outer wall of the connecting slide 3112. A push plate 3117 is fixedly connected to the side of the outer wall opposite the force block 3113. A rotating hole is opened in the inner wall of the filter box 313. A torsion spring 3114 is fixedly connected to the inner wall of the rotating hole. The end of the torsion spring 3114 away from the inner wall of the rotating hole is fixedly connected to a rotating shaft 3115. The outer wall of the rotating shaft 3115 is rotatably arranged on the inner wall of the rotating hole. The bottom end of the outer wall of the rotating shaft 3115 is fixedly connected to a baffle 3116.

[0028] Furthermore, there are two positioning holes 315 and two positioning rods 316 respectively, and the positioning holes 315 and the positioning rods 316 are distributed in a left-right symmetrical structure on the filter plate 314 and the filter box 313, so that the left and right sides of the filter plate 314 can be positioned synchronously, thereby ensuring the installation stability of the filter plate 314.

[0029] Furthermore, the outer wall of the positioning rod 316 fits snugly with the inner wall of the positioning hole 315 , and the inner wall of the snap-fitting groove at the top of the inner wall of the filter box 313 fits snugly with the outer wall of the filter plate 314 , thereby ensuring the installation stability of the filter plate 314 .

[0030] Furthermore, one side of the connecting chute opened on the outer wall of the filter box 313 passes through the outer wall of the filter box 313, and the outer wall of the connecting slide rod 3112 fits well with the inner wall of the connecting chute. The length of the connecting slide rod 3112 is longer than the inner wall of the connecting chute. In this way, it can be ensured that the connecting slide rod 3112 can always block the connecting chute during the sliding process to prevent the loss of internal synthetic gas.

[0031] The crushing and transmission mechanism 32 includes a fixed plate 321 fixedly connected to the top of the preparatory furnace 2, a motor 322 fixedly connected to the bottom end of the fixed plate 321, a connecting shaft 323 fixedly connected to the output end of the motor 322, a crushing knife 324 fixedly connected to the outer wall of the connecting shaft 323, a hoist 325 is provided at the bottom end of the preparatory furnace 2, and a first transmission pipe 326 and a second transmission pipe 327 are respectively connected to the outer walls of the left and right sides of the preparatory furnace 2.

[0032] Furthermore, there are a plurality of crushing knives 324 , which are evenly and equidistantly distributed in a cross-like pattern on the outer wall of the connecting shaft 323 , so that the biomass raw materials can be crushed more evenly.

[0033] Furthermore, the first transmission pipe 326 is connected and arranged above the preparatory furnace 2, and the second transmission pipe 327 is connected and arranged below the preparatory furnace 2. In this way, high-temperature gas can be simultaneously transported to the upper and lower sections of the interior of the preparatory furnace 2 through the first transmission pipe 326 and the second transmission pipe 327 to accelerate the temperature increase inside the preparatory furnace 2.

[0034] The implementation principle of a biomass pyrolysis and gasification system for synthesizing green methanol in this embodiment is as follows: the biomass raw materials burned in the gasifier 1 will produce synthesis gas, which is then transmitted to the filter box 313 through the connecting pipe 312, and the synthesis gas is filtered by the filter plate 314. When the filter plate 314 needs to be replaced or disassembled, the pull rod 319 can be pulled to drive the fixed plate 321 to move outward. At the same time, the fixed plate 321 will drive the positioning rod 316 to move outward, and then drive the spring 318 to stretch. At this time, the positioning rod 316 will be separated from the inner wall of the positioning hole 315 opened on the outer wall of the filter plate 314, releasing the limiting effect on the filter plate 314, and then the filter plate 314 will be separated from the inside of the filter box 313, completing the disassembly. At the same time, when pulling the fixed plate 321 to move, it can also drive the connecting rod 3110 to move. The baffle 3116 is squeezed and the rotating shaft 3115 is driven by the torsion spring 3114 to rotate, thereby driving the dust and impurities and the dust impurities falling on the push plate 3117 to be cleaned, thereby facilitating the cleaning of the staff.

[0035] Before incineration, the biomass raw materials are put into the preparatory furnace 2, and the motor 322 is started synchronously. Its output end will drive the connecting shaft 323 and the crushing knife 324 to rotate. The crushing knife 324 can crush large pieces of biomass raw materials into small pieces. At the same time, the high-temperature gas burned in the gasification furnace 1 will be transported to the preparatory furnace 2 through the first transmission pipe 326 and the second transmission pipe 327. In this way, the biomass raw materials can be dried while being chopped to prevent excessive moisture from absorbing heat during the pyrolysis process and affecting the pyrolysis effect. Finally, the processed biomass raw materials are transported to the gasification furnace 1 through the elevator 325, which can improve the preparation efficiency of the biomass raw materials.
