Description

Technical Field

[0001] This utility model relates to the technical field of distillation apparatus, and in particular to a bromine distillation apparatus. Background Technology

[0002] Bromine distillation equipment plays a vital role in the chemical industry, especially in the extraction and purification of bromine. As an important chemical element, bromine has wide applications in many fields such as flame retardants, pesticides, and pharmaceuticals.

[0003] Currently, in the equipment for bromine distillation, such as the patent with authorization announcement number CN216629711U, this utility model discloses a heat exchange heating device for a bromine distillation column, specifically involving the field of distillation columns. It includes a distillation column, a distillation heating vessel at the bottom of the distillation column, a steam pipe fixedly connected to the top of the distillation column, a reflux pipe fixedly connected to the middle of one side of the distillation column, a feed pipe fixedly connected to the side of the distillation column away from the reflux pipe, and the distillation column and the distillation heating vessel are fixedly connected by a flange.

[0004] However, during the use of the device, it was found that the device was not very effective in circulating bromine, and bromine tended to deposit at the bottom of the device. Furthermore, the device was not convenient for preheating bromine with steam, which increased energy consumption. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a bromine distillation device that improves waste heat utilization, reduces the energy consumption of the tank for heating bromine, improves the convenience of bromine distillation, enhances the circulation of bromine in the tank, reduces the deposition of bromine at the bottom of the tank, and improves the processing quality.

[0006] This utility model discloses a bromine distillation apparatus, comprising a tank and a steam pipe connected to the upper part of the outer wall of the tank; it also includes a stirring device, a heat exchange device, a circulation pipe, a first pump body, a delivery pipe, and multiple sets of reflux ports. The upper and lower ends of the circulation pipe are installed on the inner wall of the tank. The first pump body is installed at the bottom of the tank, and its output end is connected to the bottom end of the circulation pipe. The delivery pipe is connected to the input end of the first pump body, and multiple input ends of the delivery pipe are connected to the tank. Multiple sets of reflux ports are connected to the upper part of the outer wall of the circulation pipe. The stirring device is located inside the tank and is used to stir the bromine. The heat exchange device is connected to the tank and the steam pipe and is used to preheat the bromine. Bromine is transported to the tank via a heat exchanger. The bromine is heated within the tank, and the heated steam is then transported to the heat exchanger via a steam pipe. The heat exchanger uses the heat of the steam to preheat the bromine passing through it, while simultaneously cooling and condensing the steam due to the bromine's temperature. This improves waste heat utilization, reduces the energy consumption of the tank for heating the bromine, and enhances the convenience of bromine distillation. The first pump is activated, drawing bromine from the bottom of the tank through a delivery pipe. The drawn bromine is then transported to a circulation pipe and discharged through multiple reflux ports, improving the circulation of bromine within the tank, reducing bromine deposition at the bottom, and improving processing quality.

[0007] Preferably, the heat exchange device includes a conveying device, a heat exchange box, a distillation discharge pipe, an inlet pipe, a gas discharge pipe, a baffle plate, and a heat exchanger.

The discharged steam is transported to the inside of the heat exchanger, and the bromine to be refined is transported to the heat exchange box above the baffle through the inlet pipe, so that the bromine is stored in the heat exchange box. When the steam flows through the heat exchanger, the heat of the steam heats the heat exchanger, which in turn heats the bromine stored in the heat exchange box. At the same time, the steam cools down and condenses. The condensed steam drips to the bottom of the heat exchange box, and the remaining gas is discharged out through the gas outlet pipe. When the bromine stored in the heat exchange box reaches the predetermined temperature, it is transported to the tank for refinement through the conveying device, which improves the convenience of use.

[0008] Preferably, the stirring device includes a kit, a motor, and a stirring paddle. The kit is rotatably mounted on the upper part of the tank and is rotatably fitted onto the upper part of the outer wall of the circulation pipe.

The stirring paddle is mounted on the outer wall of the kit, and the lower part of the stirring paddle is rotatably fitted onto the outer wall of the circulation pipe. The motor drives the kit to rotate, which in turn drives the stirring paddle to rotate, thereby mixing and stirring the bromine in the tank, improving the heating uniformity of the bromine.

[0009] Preferably, it also includes an inner liner, which is disposed on the inner side wall of the tank; by circulating and transporting a heat-conducting medium in the inner liner, the heat-conducting medium heats the inner liner, and the inner liner heats, evaporates and distills the bromine in the tank through heat conduction.

[0011] Preferably, it also includes a thermometer, which is connected and installed on the outer wall of the heat exchange box; by setting the thermometer to measure the temperature of the preheated bromine in the heat exchange box, it is convenient to deliver the preheated bromine to the tank in a timely manner.

[0012] Preferably, it also includes an exhaust hood, which is connected to the outlet end of the gas exhaust pipe; by providing an exhaust hood, the convenience of protecting the outlet end of the gas exhaust pipe is improved.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: bromine is transported to the tank through a heat exchange device. By heating the bromine in the tank, the heated steam is transported to the heat exchange device through a steam pipe. The heat exchange device uses the heat of the steam to preheat the bromine passing through it, while the temperature of the bromine cools and condenses the steam, thereby improving the waste heat utilization effect, reducing the energy consumption of the tank for heating bromine, and improving the convenience of bromine distillation.
