DETAILED DESCRIPTION:

[0017] As Figure 2 And Figure 4 As shown in a kind of, a glyoxal activated carbon decoloring device, it includes shell 1, liquid inlet pipe 4, liquid outlet pipe 5 are respectively arranged at the top end and bottom end of the shell 1, a plurality of decoloring tanks 2 are arranged in the shell 1 and inclined downwards along the height direction, activated carbon particles 6 are contained in the decoloring tank 2, opening 16 is arranged at the left and right ends of the decoloring tank 2, the decoloring tank 2 is made of porous plate, material port is formed on the outer wall of the shell 1 and matched with the opening 16, sealing plate 8 is fixedly covered on the material port, vibration assembly is arranged at the bottom end of the shell 1, and vibration motor 15 is mounted at the top end of the shell 1.

[0018] AsFigure 3 As shown, limiting plates 3 that match the position of the decolorizing box 2 are connected to the inner walls on both sides of the housing 1, and the decolorizing box 2 is placed on the limiting plates 3.

[0019] like Figure 1 and Figure 4 As shown, a pin hole 13 is provided on the outer wall of the decolorizing box 2, and a through hole matching the pin hole 13 is provided on the outer wall of the housing 1. A positioning pin 14 is inserted into the through hole and the pin hole 13.

[0020] like Figure 2 and Figure 4 As shown, in order to prevent liquid glyoxal from flowing along the inclined direction of the decolorization box 2, resulting in uneven adsorption of activated carbon particles 6, several baffles 12 are installed on the top surface of the decolorization box 2 along the length direction, and the angle between the decolorization box 2 and the horizontal direction is 8°.

[0021] To further ensure the uniformity of activated carbon adsorption, such as Figure 1 and Figure 2 As shown, several water spray pipes are installed along the length of the liquid inlet pipe 4, and a nozzle 7 is installed at the bottom end of the water spray pipe. The nozzle 7 is located inside the housing 1.
