Description

Technical Field

[0001] This utility model relates to the technical field of evaporators, and in particular to a multi-stage evaporator for bromine. Background Technology

[0002] Bromine is an important chemical raw material, widely used in fire prevention, chemical synthesis, pharmaceutical preparations, electronic materials, photography, oilfield chemistry and many other fields. In the extraction and purification process of bromine, the evaporator is a key piece of equipment, and its performance directly affects the production efficiency and product quality of bromine.

[0003] For example, in existing evaporation equipment, the patent with authorization announcement number CN220736212U belongs to the field of evaporation kettle technology. Specifically, it is a multi-stage evaporation kettle, including a bottom plate. The upper end face of the bottom plate is fixedly connected to a first evaporation kettle and a second evaporation kettle distributed on the left and right. The upper end face of the bottom plate is fixedly connected to a heating box located between the first evaporation kettle and the second evaporation kettle. The interior of the first evaporation kettle and the second evaporation kettle are both provided with spiral tubes, and a connecting pipe that passes through the first evaporation kettle and the second evaporation kettle is connected between the two spiral tubes.

[0004] However, during the use of the equipment, it was found that it was not convenient to use the heat from multi-stage evaporation to preheat the bromine, which increased the energy consumption of the equipment and reduced the ease of use. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a multi-stage evaporator for bromine that facilitates preheating of bromine, reduces heating energy consumption, and improves working efficiency.

[0006] This utility model discloses a multi-stage evaporator for bromine, comprising a tank and a feed valve, the feed valve being connected to the upper part of the outer wall of the tank; it also includes a moving device, a stirring device, a funnel, a plug, and a heat-conducting inner liner. The funnel is located on the upper part of the inner wall of the tank, and multiple sets of vents are provided on the outer wall of the tank below the funnel. The plug is located at the bottom opening of the funnel. A moving device is provided on the tank for moving the plug up and down. The heat-conducting inner liner is installed on the lower part of the inner wall of the tank. A stirring device is located in the lower part of the tank for mixing and stirring the bromine, and also for discharging any remaining bromine in the tank; the bromine is then conveyed to the... Inside the tank, bromine enters and falls to the bottom through a funnel. The heat-conducting inner liner is heated, causing the bromine to undergo multi-stage evaporation at different temperatures. The evaporated gas at the bottom of the tank is discharged through the exhaust port. At this point, a plug seals the funnel opening. Bromine is then fed back into the tank through the feed valve, storing it above the funnel. The evaporation temperature heats the funnel, preheating the stored bromine. Once the remaining bromine in the lower part of the tank is discharged, the bromine above the funnel is discharged into the lower part of the tank for multi-stage evaporation, reducing heating energy consumption and improving work efficiency.

[0007] Preferably, the moving device includes a bracket, an internal threaded sleeve, a worm gear, a worm, a first motor, and a screw. The bracket is located at the top of the tank. The internal threaded sleeve is rotatably mounted on the outer wall of the bracket. The worm gear is mounted on the outer wall of the internal threaded sleeve. The worm is rotatably mounted on the outer wall of the bracket and meshes with the worm gear. The first motor is mounted on the outer wall of the bracket, and the output end of the first motor is connected to the worm. The screw is slidably mounted on the inner wall of the tank. The upper part of the screw is screwed onto the internal threaded sleeve, and the bottom end of the screw is connected to the plug. The first motor drives the worm to rotate, which in turn drives the internal threaded sleeve to rotate through meshing with the worm gear. After the internal threaded sleeve rotates, it drives the screw to move up and down, thereby causing the screw to move up and down the plug, improving the convenience of bromine emission control at the top of the funnel.

[0008] Preferably, the stirring device includes a conveying box, a hollow shaft, a second motor, a pump body, and stirring blades. The conveying box is installed at the bottom of the tank. The lower part of the hollow shaft is rotatably installed inside the conveying box, and the upper part of the hollow shaft rotatably extends into the tank, with the upper part of the hollow shaft communicating with the tank and the lower part communicating with the conveying box. The second motor is installed at the bottom of the conveying box, and its output end is connected to the hollow shaft. The pump body is installed on the outer wall of the tank, and its input end is connected to the conveying box. The stirring blades are installed on the outer wall of the hollow shaft. The second motor drives the hollow shaft to rotate, causing the hollow shaft to mix and stir the bromine through the stirring blades, improving the uniformity of the multi-stage evaporation of bromine and improving the processing quality. When it is necessary to discharge the remaining concentrated bromine from the tank, the pump body is turned on, allowing the pump body to discharge the bromine from the tank through the conveying box and the hollow shaft, improving ease of use.

[0009] Preferably, the device also includes a collection hood and a blower. The collection hood is installed on the outer wall of the tank and is connected to multiple sets of exhaust ports of the tank. The blower is connected to and installed on the collection hood. The steam discharged from the tank is collected by the collection hood, and the convenience of transporting the collected steam is improved by turning on the blower.

[0010] Preferably, it also includes an electric heating element, which is installed on the inner wall of the heat-conducting inner liner; the heat-conducting inner liner is heated by the electric heating element, so that the heat-conducting inner liner heats and evaporates the bromine in the tank.

[0011] Preferably, a temperature sensor is installed inside the tank to improve the convenience of measuring the bromine multi-stage evaporation temperature and preheating temperature.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: Bromine is conveyed into the tank through the feed valve. The bromine entering the tank falls to the bottom of the tank through the funnel. By heating the heat-conducting inner liner, the bromine in the tank undergoes multi-stage evaporation treatment at different temperatures. The gas evaporated at the bottom of the tank is discharged outward through the exhaust port. At this time, the plug seals the opening of the funnel. Bromine is then conveyed into the tank again through the feed valve, so that the bromine is stored above the funnel. The evaporation temperature heats the funnel, thus preheating the bromine stored above it. When the remaining bromine in the lower part of the tank is discharged, the bromine above the funnel is discharged into the lower part of the tank for multi-stage evaporation treatment, reducing heating energy consumption and improving working efficiency.
