AI Technical Summary

Problems solved by technology

Phenolic resin powder is obtained by grinding phenolic resin particles with a pulverizer. The diameter of the ground phenolic resin powder is distributed between 2-30 microns, mainly between 8-20 microns. The powder is relatively coarse, and the phenolic resin is in different diameter ranges. The large distribution range and poor consistency make it difficult to improve the adsorption capacity of carbon molecular sieves.

Embodiment 1

[0020] Example 1. Carbon molecular sieve raw material crushing system, such as figure 1 As shown, the coarse grinding pulverizer 1 and the coarse grinding pulverizer 1 are connected to the first feed bin 3 through the first transmission mechanism 2 of one-way feeding, and the first feed bin 3 is connected to the heating furnace 5 through the conveyor 4, and the heating furnace 5 The furnace temperature is 400-500°C, the discharge end of the heating furnace 5 is provided with a fine grinder 6, and the fine grinder 6 is connected to the second feed bin 8 through the second transmission mechanism 7 of one-way feeding, and the second feed bin 8 The discharge end is provided with a fine grinding pulverizer 10, and the fine grinding pulverizer 10 is connected to the third silo 11 through the third transmission mechanism 9 of one-way feeding.

[0021] The first transmission mechanism 2 includes a first collecting hopper 21 arranged on the top of the first silo 3, the first collectin...

Embodiment 2

[0032] Example 2. The difference from Embodiment 1 is that the system does not have the third shut-off fan 28 and the sixth shut-off fan 77 .

[0033] The phenolic resin powder of Example 1 is compared with the phenolic resin powder of Example 2, and the following table 1 results are obtained.

[0034] Example 1 Example 2 Overall diameter range (microns) 1-5 1-7 1-2 micron diameter range content 4％ 3％ 2-3 micron diameter content 79％ 64％ 3-4 micron diameter content 12％ 17％ 4-5 micron diameter content 5％ 9％ 5-7 micron diameter content 0 7％

[0035] Table 1

[0036] As can be seen from Table 1, the existence of the third fan 28 and the sixth fan 77 makes the phenolic resin pulverized finer, and the distribution range on different diameter ranges is small, and mainly concentrated in 2-3 microns, consistent Sex is better.

[0037] Based on Example 1, by adjusting the temperature of the furnace, the contents of Table 2 a...

Description

technical field [0001] The invention belongs to the field of carbon molecular sieve raw material processing, and in particular relates to a carbon molecular sieve raw material crushing system and process. Background technique [0002] The raw material of carbon molecular sieve is phenolic resin powder. After adding glue, the phenolic resin powder is extruded in the extrusion molding machine, and then cut into granules. The granules are carbonized and adjusted to form carbon molecular sieve. The finer the phenolic resin powder, the higher the adsorption capacity of the carbon molecular sieve. Phenolic resin powder is obtained by grinding phenolic resin particles with a pulverizer. The diameter of the phenolic resin powder obtained by grinding is distributed between 2-30 microns, mainly between 8-20 microns. The powder is relatively coarse, and the phenolic resin is in different diameter ranges. The large distribution range and poor consistency make it difficult to improve th...
