[0021] Two decolorization layers 6 are arranged in the upper tower 3, and the two decolorization layers 6 divide the upper tower 3 into chamber one 35, chamber two 36 and chamber three 37; two decolorization layers 6 are arranged in the lower tower 4, and the two decolorization layers 6 divide the lower tower 4 into chamber four 43, chamber five 44 and chamber six 45; stirring rods 52 are arranged in chamber two 36 and chamber five 44, and the top of the stirring rod 52 is connected to the output end of the motor 51, and the two motors 51 are respectively located in the top 32 and the bottom one 31, and stirring blades are arranged on the stirring rod 52. The setting of the stirring mechanism 5 makes the glycerin more evenly distributed in the tower, avoids the accumulation of glycerin at the bottom of the tower, accelerates the flow of glycerin, and improves the decolorization efficiency.

[0022] Different structures of decolorizing layers 6 can be used for different pigment contents of glycerol. For glycerol with low pigment content, only the decolorizing layer 6 can be used without adding other layered structures; Figure 2As shown, when there is a little more pigment, a plurality of side-by-side primary decolorizing tubes 61 can be arranged in the decolorizing layer 6, and the primary decolorizing tubes 61 are cylindrical and the cross sections of adjacent primary decolorizing tubes 61 are tangent; when the pigment content is high and thorough decolorization is required, a plurality of secondary decolorizing tubes 62 can be selected to be set in the primary decolorizing tube 61, such as Figure 3 The secondary decolorizing tubes 62 shown may be four and arranged in a circumferential distribution, such as Figure 4 The secondary decolorizing tubes 62 shown may also be arranged in a petal shape, wherein the secondary decolorizing tubes 62 are cylindrical and the cross sections of adjacent secondary decolorizing tubes 62 are tangent.

[0023] When in use, the glycerol to be decolorized is input into chamber one 35 through the glycerol inlet 33, filtered through the decolorization layer 6 in the process of reaching chamber two 36 from chamber one 35, stirred by the stirring mechanism 5 after reaching chamber two 36, and the stirred glycerol enters chamber three 37, and is filtered through the decolorization layer 6 again before entering chamber three 37; from chamber three 37 to chamber four 43 through the glycerol outlet one 34, and reaches chamber five 44 from chamber four 43 to be filtered through the decolorization layer 6 for the third time, and is stirred by the stirring mechanism 5 in chamber five 44, and passes through the decolorization layer 6 for the fourth time to reach chamber six 45, and the decolorized glycerol is discharged from chamber six 45 through the glycerol outlet two 42 to enter the next link.

When replacement is required, open the top cover 2, pull out the parts to be replaced from the opening 7, and then put the replacement parts in from the opening 7. If the filter tube in the lower tower 4 needs to be replaced, remove the upper tower 3, the decolorization layer 6 will be fully displayed, pull out the parts to be replaced, and reinstall the upper tower 3 after the replacement is completed. During the installation process, put the top of the decolorization layer 6 into the groove 8, so that the decolorization layer 6 in the lower tower 4 can be more secure.
