DETAILED DESCRIPTION

[0018] The technical scheme of the utility model will be further described below by examples and in conjunction with the drawings.

[0019] Example:

[0020] The utility model discloses a kind of decoloring devices for monosodium glutamate production, as shown in Fig. Figure 1 It includes tank body, tank cover 3, stirring mechanism and heat exchange coil 7, tank cover 3 is equipped with feeding port 4, and feeding port is equipped with feeding valve, and stirring mechanism is fixedly arranged on tank cover, and stirring mechanism includes stirring motor 5 and stirring paddle 6, and tank body includes decoloring tank 2 and water bath tank 1, decoloring tank 1 is located in water bath tank 2, and supporting column 10 is arranged between the bottom end of decoloring tank 1 and the bottom surface of water bath tank 2, and supporting column 10 is provided with through hole for communicating decoloring tank and the outside of tank body, and discharging mechanism is movably arranged in through hole. Heat exchange coil 7 is arranged in water bath tank.

[0021] The lower inner wall of the through hole inside the support column 10 is provided with threads, and the discharging mechanism is movably arranged in the through hole through the threads. The discharging mechanism comprises a hollow screw rod 11 and a piston head 13, the piston head 13 is fixedly arranged on the upper end of the hollow screw rod 11, the piston head 13 is provided with a plurality of through holes 14 on the side surface, each through hole 14 is communicated with the internal hollow 12 of the hollow screw rod 11, and the lower end of the hollow screw rod is provided with a discharging valve 15. In addition, a force applying handle 16 is arranged at the lower end of the hollow screw rod 11. During discharging, the hollow screw rod is rotated by the force applying handle to move upward so that the through holes on the side of the piston head enter the decolorizing tank, at this time the monosodium glutamate solution in the decolorizing tank can be discharged through the internal hollow of the hollow screw rod. In addition to the function of facilitating the rotation of the hollow screw rod, the force applying handle can also limit the position of the hollow screw rod to avoid the piston head from being in contact with the stirring paddle 6 due to excessive upward movement of the hollow screw rod.

[0022] The heat exchange coil 7 is spirally arranged in the water bath tank 1 from top to bottom and does not contact the outer wall of the decolorizing tank 2. The input end 8 of the heat exchange coil is located on the side surface of the upper end of the water bath tank 1 and is connected with the high-temperature exhaust gas output end of the crystallization tank, and the output end of the heat exchange coil 9 is located on the side surface of the lower end of the water bath tank 1 and is connected with the condensed water collector and the adsorber. The high-temperature exhaust gas output by the crystallization tank is subjected to heat exchange with the liquid in the water bath tank through the heat exchange coil, so that the temperature of the liquid in the water bath tank rises, thereby water-bath heating the decolorizing tank to make the monosodium glutamate solution in the decolorizing tank uniformly heated. The condensed water generated in the heat exchange process can flow into the condensed water collector along the heat exchange coil under the action of gravity, and the volatile organic compounds in the high-temperature exhaust gas can be adsorbed by the adsorber. In addition, in order to facilitate the control of the water temperature in the water bath tank, a temperature control mechanism and a temperature sensor are arranged in the water bath tank. The temperature of the water in the water bath tank is detected by the temperature sensor, and the temperature control mechanism is used for regulation and control when the water temperature is too high or too low. The temperature control mechanism can be an electric heating wire and a radiator, or a semiconductor thermoelectric device.

[0023] The decolorizing device for monosodium glutamate production in the embodiment utilizes the water bath tank to water-bath heat the decolorizing tank, so that the monosodium glutamate solution in the decolorizing tank is uniformly heated and the temperature of the monosodium glutamate solution is kept consistent, thereby facilitating the control of the temperature of the monosodium glutamate solution. The heat energy of the high-temperature exhaust gas discharged by the crystallization tank is recovered through the heat exchange coil, and the collection of condensed water and the adsorption of volatile organic compounds are completed at the same time of heat energy recovery, thereby effectively reducing the production cost.
