[0026] Please refer to FIG. 1 and FIG. 3; second embodiment

[0027] The utility model provides a kind of fungus cap assembly, including cap 1 and the lower disc 2 of being arranged in the lower part of cap 1.

[0028] Cap 1 and lower disc 2 are all hollow structure's conical wall, the conical vertex of cap 1 is upwards, and the conical vertex of lower disc 2 is downwards;Liquid phase follows cap 1 and flows into the space between cap 1 and lower disc 2;The upper end outside of the conical wall of lower disc 2 is fixedly connected with the inner wall of carbonization tower.

[0029] A through hole 4 is arranged at the center of the conical wall of lower disc 2, which facilitates the passage of gas phase and liquid phase. The through hole 4 can be a round hole, an oval hole, a rectangular hole, a triangular hole, or other polygonal holes, as well as irregularly shaped holes. The edge of the through hole 4 can be serrated to further break up the gas and increase the reaction area.

[0030] A plurality of through holes 5 are provided around the through hole 4. The number of through holes 5 is 0-16. If no through holes 5 are provided, or 8 or 16 through holes 5 are provided. Similarly, the through holes 5 can be round holes, oval holes, triangular holes, rectangular holes, or other polygonal holes, as well as irregularly shaped holes, as shown in Figure 2. This is not limited here, and can meet the actual production needs. The lower disc 2 is provided so that the gas passes through the holes at different positions of the lower disc 2, the gas is evenly and smoothly distributed, the gas-liquid contact is sufficient, and the crystals do not accumulate on the lower disc, which is not easy to block.

[0031] Cap 1 and lower disc 2 are connected by a connecting piece 6. The distance between the horizontal plane where the edge of cap 1 is located and the horizontal plane where the edge of lower disc 2 is located is 50-200 mm, such as 50 mm or 150 mm or 200 mm. A certain spacing is left to make the gas rotate and diffuse in the space between cap 1 and lower disc 2, reserve enough space for gas-liquid contact and reaction, and improve the gas-liquid contact area and mass transfer efficiency. The spacing cannot be too large, so that the fungus cap can effectively prevent the splashing of liquid and ensure stable reaction in the device. The spacing also cannot be too small, and enough space needs to be reserved to increase the gas-liquid contact area and contact time.

[0032] The angle between the side wall surface of cap 1 and the horizontal plane is 3-20 degrees, such as 3 degrees or 10 degrees or 20 degrees, which can effectively prevent the accumulation of crystals on the upper surface of the fungus cap. If the angle is smaller, the crystals will accumulate on the cap in large quantities. If the angle is too large, the gas phase will accumulate excessively between the cap 1 and the lower disc, which will affect the gas-liquid mass transfer and structural stability. The angle between the side wall surface of the lower disc and the horizontal plane is 3-20 degrees, such as 3 degrees or 10 degrees or 20 degrees, which also cannot be too large or too small.

[0033] In summary, the structure of the application is set so that the gas-liquid reaction is complete, the occurrence of local supersaturation is reduced, the generation rate of crystallization is reduced, and the possibility of crystallization accumulation is reduced as much as possible by different settings of different structure parameters. Second embodiment

The design of the serrated edge part 7 breaks the gas into more smaller bubbles when passing through the teeth, thereby increasing its dispersion degree to increase the area of the interfacial surface. Third embodiment

Fourth embodiment

[0036] Based on the content of the foregoing embodiments, preferably, the connecting piece 6 can be a rib plate, and multiple rib plates are provided to avoid unstable connection of the cap 1 and affect the stability and continuity of production. Fifth embodiment

[0037] Based on the content of the foregoing embodiments, the included angle of the inclined part of the cap 1 and the lower disc 2 is preferably in the range of 5° to 16°, which can more effectively prevent crystallization accumulation caused by too small included angle and gas phase accumulation between the cap and the lower disc caused by too large included angle. Sixth embodiment

[0038] Based on the content of the foregoing embodiments, the flow path of the liquid phase in the carbonization tower is that the liquid phase flows along the upper surface of the cap to the space reserved between the cap and the lower disc, and then flows out along the through hole and the through hole on the lower disc, thereby falling to the next layer; the path of the gas phase in the carbonization tower is opposite to that of the liquid phase. The setting of the application prolongs the flow paths of the gas and liquid phases, so that they are in sufficient contact and reaction in the space between the cap and the lower disc.

[0039] Based on the above device, a larger gas-liquid contact area and a longer reaction channel are provided for the reaction.
