The following embodiments are described in detail with reference to the accompanying drawings.

[0026] A decolorization tank device based on plate heat exchange includes a decolorization tank body and a decolorization liquid heat exchange structure, wherein:

[0027] The decolorizing tank has a feed inlet 4, an activated carbon or crude product feed inlet 5, a stirring motor 6, a washing inlet 7, a hot water inlet 8, and a return liquid inlet 9 on its top. The middle and bottom of the decolorizing tank are wrapped with a heat insulation layer 10, which is made of anti-aging pearl cotton.

[0028] The decolorizing liquid heat exchange structure includes a plate heat exchange structure and a heat exchange frame for mounting the plate heat exchange structure. The heat exchange frame is provided with several sets of parallel-arranged support columns and guide rods. The plate heat exchange structure includes several parallel-arranged metal plates, flow channels formed between adjacent metal plates, and sealing gaskets for sealing the edges of the metal plates. The flow channels include adjacent and independent hot medium flow channels and cold medium flow channels. The cold medium outlet of the plate heat exchange structure is connected to the inlet of the decolorizing tank via a pipe. The plate heat exchange structure is clamped and fixed by guide rods and clamping bolts, and then mounted on the heat exchange frame by support columns. These components together constitute the basic structure of the decolorizing liquid heat exchange structure, enabling it to effectively exchange heat.

[0029] In this embodiment, as Figure 1 As shown, the decolorizing tank device includes a decolorizing tank body, a plate heat exchange structure, 316 stainless steel pipes, and anti-aging pearl cotton. Anti-aging pearl cotton is used as an insulation layer 10 to wrap the outside of the decolorizing tank. The decolorizing tank body is made of 316 stainless steel. The top of the decolorizing tank body has a feed inlet 4, an activated carbon and crude product feed inlet 5, a stirring motor 6, a hot water inlet 8, a washing inlet 7, and a reflux liquid inlet 9. Anti-aging pearl cotton is used as an insulation layer to wrap the outside of the decolorizing tank. In addition to being used as a decolorizing tank, the decolorizing tank can also be used directly as a reconstitution tank, which can save production energy and improve enterprise production efficiency.

[0030] The plate heat exchanger structure directly raises the temperature of the decolorizing liquid before it enters the decolorizing tank, which is insulated with anti-aging pearl cotton. This provides excellent insulation for the decolorizing tank. Specifically, the plate heat exchanger structure consists of many parallel metal plates and sealing gaskets. The heat exchange frame includes guide rods, clamping bolts, and supports. The plate heat exchanger structure is installed on the left side of the decolorizing tank via the heat exchange frame. The outlet of the cold medium in the plate heat exchanger structure is connected to the inlet of the decolorizing tank. The fluid flows in the channels between the plates, and heat is transferred from the high-temperature fluid to the low-temperature fluid (cold medium) through the plates. Due to its large heat exchange area and small channels, the plate heat exchanger structure has high heat transfer efficiency. Furthermore, because the plates are closely arranged, the plate heat exchanger structure occupies a small area. Due to its high efficiency, the plate heat exchanger structure can reduce energy consumption, thereby reducing its environmental impact. The plate heat exchange structure is clamped and fixed by guide rods and clamping bolts, and then installed on the heat exchange frame by support columns. It has a compact structure and occupies a small area. Brakeable casters can also be installed at the bottom of the heat exchange frame to facilitate the movement and fixation of the decolorizing liquid heat exchange structure.

[0031] This decolorization tank device has a reasonable structural design and high efficiency. It can directly pass the decolorization liquid (cold medium) into the plate heat exchange structure for rapid heating, reducing heat loss and solving the problem of low heat exchange efficiency.

[0033] Furthermore, in this embodiment, the decolorizing tank inlet 4, carbon addition port or crude product inlet 5, washing port 7, hot water inlet 8, and reflux port 9 are located at the top of the decolorizing tank. The inlet 4 and reflux port 9 are used to pump the liquid or fermentation liquid into the decolorizing tank. The carbon addition port or crude product inlet 5 is used to pump activated carbon into the decolorizing tank to decolorize the liquid. The carbon addition port or crude product inlet 5 and hot water inlet 8 are used to mix the crude product and hot water, so that the decolorizing tank can be used as a reconstitution tank. The washing port 7 is used to evenly clean the inside of the decolorizing tank with cleaning water.

[0034] Furthermore, in this embodiment, the washing head inside the washing port 7 is a rotary tank washing nozzle, designed to conveniently and comprehensively clean and disinfect the decolorization tank.

[0035] Furthermore, in this embodiment, temperature electrode interfaces 11 are provided in the middle and bottom of the decolorizing tank. The temperature electrode interfaces 11 are arranged at an angle on the decolorizing tank to ensure uniform temperature of the decolorizing liquid and achieve better decolorization effect.

[0036] Furthermore, in this embodiment, the bottom of the decolorizing tank is provided with a sampling port 15 and a discharge port 16. The sampling port 15 is set at the discharge port 16 at the bottom of the decolorizing tank to extract samples from the decolorizing tank in order to monitor the status of the decolorization process.

[0037] Furthermore, in this embodiment, the bottom of the decolorizing tank is also provided with a decolorizing tank support 14, with 4 support pillars at the bottom of the decolorizing tank to ensure that the decolorizing tank can stand stably.

[0038] Furthermore, in this embodiment, when the decolorizing tank is used as a resolution tank, the activated carbon or crude product inlet 5 can be used in conjunction with the hot water inlet as a crude product inlet.

[0039] Furthermore, in this embodiment, a stirring device can be provided inside the decolorization tank. The stirring device includes a stirring rod 12 and a stirring blade 13. The stirring rod 12 is fixedly connected to the stirring motor 6. The stirring blade 13 is mounted on the outside of the stirring rod 12. The stirring motor 6 is located at the center of the top of the decolorization tank. The stirring rod 12 is connected to the motor. The stirring blade 13 is fixedly installed above the stirring rod inside the decolorization tank, so that the fermentation liquid and activated carbon are stirred more evenly.

[0040] Furthermore, in this embodiment, the stirring blade 13 can be hinged to the outside of the stirring blade assembly via a connecting shaft and locked in place by locking bolts. The stirring blade assembly is fixedly installed on the stirring rod 12. The stirring blade 13 is hinged to the outside of the stirring blade assembly via a connecting shaft, and the stirring blade 13 can swing up and down outside the stirring blade assembly via the connecting shaft. At the required angle, it can be locked in place by locking bolts to meet different stirring needs.

[0041] Furthermore, in this embodiment, the heat exchange frame can be a 316 stainless steel cubic frame structure, and the heat exchange frame is placed on the side of the decolorization tank.

[0044] Working Principle: In operation, the decolorizing device based on plate heat exchange first introduces the liquid to be decolorized through the cold medium inlet 1 of the plate heat exchange structure. Heat is exchanged through the plate heat exchange structure, and then the liquid is pumped into the decolorizing tank inlet 4 via a pipe through the outlet 2. Activated carbon is then added to the decolorizing tank through the carbon addition hole 5. The middle and conical bottom of the decolorizing tank are insulated with anti-aging pearl cotton as a heat preservation layer 10 to keep the incoming fermentation liquid warm. The stirring motor 6 is turned on and adjusted to a suitable speed to stir the fermentation liquid, making the decolorization effect more uniform and promoting the adsorption effect of the activated carbon. Temperature electrodes 11 in the middle and bottom of the tank are used to monitor the temperature of the decolorizing liquid; a sample is taken through the sampling port 15 at the bottom of the conical tank to observe whether the decolorization effect meets the standards. Once the decolorizing liquid reaches the technical specifications, it is discharged through the outlet 16 at the bottom of the tank. The decolorization tank is equipped with both a hot water inlet 8 and a crude product inlet 5, which are used as a reconstitution tank for the crude product. Then, washing water is added to the decolorization tank through the washing inlet 7, and the washing head is used to disperse the washing water to better clean the inside of the decolorization tank.
