Description

Technical Field

[0001] The invention relates to the technical field of aspartame production, in particular to an acid mist absorption device used for aspartame production. Background Art

[0002] Aspartame is a non-carbohydrate artificial sweetener, and some acidic substances may be used as raw materials or catalysts in its production process. In addition, certain steps in the production process, such as reaction, distillation, purification, etc., may also produce acid mist under certain conditions. The amount and concentration of these acid mists will be affected by many factors, including the type of raw materials, reaction conditions, equipment design, operating specifications, etc. Modern industrial production usually has strict environmental protection and safety standards to control and reduce the emission of harmful substances, including acid mist, etc. Therefore, special acid mist absorption equipment is needed to absorb and purify the acid mist formed by the volatilization of acetic acid or other acidic substances during the production process to improve the working environment and reduce air pollution;

[0003] The conventional existing technical solutions have the following defects:

[0004] 1. When the acid mist enters the device and slowly rises, its single movement trajectory makes it not in sufficient contact with the absorbent, so part of the acid mist cannot be effectively absorbed, resulting in a decrease in purification efficiency and affecting the treatment effect of the exhaust gas;

[0005] 2. During the recycling of the absorption liquid, if the used absorption liquid is not filtered, a certain amount of suspended matter and impurities will accumulate. These substances will affect the contact effect between the absorption liquid and the acid mist and reduce the absorption efficiency. Summary of the invention

[0006] The object of the present invention is to provide an acid mist absorption device for aspartame production, so as to solve the defects of low purification efficiency and low utilization of absorption liquid in the existing acid mist absorption device for aspartame production.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: an acid mist absorption device for aspartame production, comprising a shell and an activated carbon plate; a box body is provided on one side of the shell, an air inlet is fixedly connected to the other end of the shell, an activated carbon plate is movably installed at the top of the shell, and a filter plate is movably installed at the bottom of the activated carbon plate, and a water spray pipe is fixedly connected at the middle position of the shell; the air inlet comprises a fan blade, a paddle blade, a first right-angle gear and a second right-angle gear; the paddle blade is bearing-mounted inside the air inlet, the first right-angle gear is fixedly installed on one side of the paddle blade, and the fan blade is bearing-mounted on the inner wall of the shell on one side of the first right-angle gear, and the second right-angle gear is fixedly installed on the bottom end of the fan blade.

[0008] Preferably, a rotating structure is formed between the blade and the air inlet, and the first right-angle gear and the second right-angle gear are meshingly connected.

[0009] Preferably, the box body comprises a water outlet pipe, a water inlet pipe, a pull-out plate, a chamber and a filter screen; the pull-out plate is movably installed inside the box body; and a sliding structure is formed between the pull-out plate and the box body.

[0010] Preferably, a filter is movably installed inside the pull-out plate, and a disassembly and installation structure is formed between the filter and the pull-out plate. A chamber is fixedly installed on the inner wall of the box at the bottom end of the pull-out plate, and a precipitant is arranged inside the chamber.

[0011] Preferably, a water outlet pipe is fixedly connected to the top of the box body on the top of the pull-out plate, and a water pump is installed at one end of the water outlet pipe, one end of the water pump extends to the interior of the shell through a conduit, and a water inlet pipe is fixedly connected to the side wall of the box body on one side of the pull-out plate, and the end of the water inlet pipe away from the box body is fixedly connected to the water spray pipe.

[0012] Preferably, the chamber comprises a connecting plate, a connecting rod, a piston and a discharge port, the connecting rod is movably mounted inside the chamber, and the connecting rod is fixedly mounted on one end of the piston.

[0013] Preferably, a connecting plate is fixedly installed at one end of the connecting rod, and the end of the connecting plate away from the connecting rod is fixedly connected to the bottom end of the pull-out plate, the outer wall of the chamber at one end of the piston is provided with a discharge port, and a cross sealing nozzle is provided inside the discharge port.

[0014] Preferably, a plurality of groups of holes are arranged inside the filter plate, and absorption plates are arranged inside the holes, and the absorption plates are arranged in a staggered manner.

[0015] Preferably, the water spray pipe comprises a dispersion disc, a turbine and a support shaft, the dispersion disc is movably mounted on the end of the water spray pipe, and a rotating structure is formed between the dispersion disc and the water spray pipe.

[0016] Preferably, a support shaft is fixedly installed inside the dispersion disk, and the support shaft is movably installed with the water spray pipe through a bearing, and a turbine is fixedly installed on the top end of the support shaft.

[0017] The acid mist absorption device for aspartame production provided by the present invention has the advantages that:

[0018] By providing a paddle, the paddle is installed inside the air inlet. When the acid mist enters the shell along with the air flow, the strong air flow drives the paddle to rotate.

[0020] By providing a box body, the used absorption liquid is pumped into the box body, and the suspended matter and impurities inside are filtered through the filter screen. When there are too many impurities on the filter screen, the filter screen can be lifted up by pulling the pull-out plate a few centimeters to clean or replace it. When the pull-out plate moves outward, the piston is driven to squeeze toward the front end through the connecting plate. The increased pressure pushes open the cross sealing nozzle in the discharge port, so that the precipitant in the chamber flows out into the box body, and the absorption liquid is reacted and precipitated, thereby realizing that the absorption liquid of the acid mist absorption device used for aspartame production can be recycled, and the use effect of the absorption liquid is improved, and the cost is reduced.
