Description

Technical Field

[0001] This utility model relates to the field of ethanol processing technology, specifically to a continuous ethanol concentration device. Background Technology

[0002] A continuous ethanol concentration unit is an industrial production system that achieves uninterrupted purification of ethanol-water mixtures through continuous feeding, dynamic evaporation, and real-time separation technologies. Its core operating mode involves the feed liquid sequentially undergoing preheating, boiling vaporization, gas-liquid separation, and condensation recovery in a closed process. The evaporation process is continuously driven by a heat source. The system intelligently regulates parameters such as temperature, pressure, and material flow rate to ensure a gradual increase in ethanol concentration, ultimately resulting in a stable output of high-purity ethanol. This unit replaces batch operation with continuous operation, offering advantages such as flexible and adjustable production capacity, high thermal energy recycling rate, precise automation control, and unlimited production cycle. It is widely used in large-scale industrial production scenarios such as fuel ethanol, pharmaceutical-grade anhydrous ethanol, and food additives.

[0003] Existing continuous ethanol concentration units are designed primarily to prevent scaling and enhance heat transfer on the inner surfaces of the tubes, but generally neglect the dynamic cleaning function of the outer surfaces. The heat source side is in a closed operation state for a long time, lacking online monitoring and automatic removal mechanisms for scale, oil stains or crystallized leaked materials adhering to the outer wall. As a result, the thermal resistance of the outer surface increases significantly due to scale accumulation over time. This not only forces the unit to compensate for the decrease in heat transfer efficiency by increasing the heat source temperature or flow rate, indirectly increasing energy consumption and equipment wear, but may also cause local corrosion or cracks to be covered by scale, creating potential leakage hazards. Ultimately, this restricts the long-term operational stability and energy efficiency optimization potential of the unit.

[0004] Therefore, we propose a continuous ethanol concentration device. Summary of the Invention

[0005] The purpose of this invention is to provide a continuous ethanol concentration device to solve the problems mentioned in the background art.

[0008] The heat exchanger is equipped with a filter mechanism, which includes a filter plate. The filter plate is fixedly connected inside the heat exchanger and has filter holes inside. A rotating rod is rotatably installed at the center inside the heat exchanger.

[0009] A cleaning mechanism is installed inside the heat exchanger. The cleaning mechanism includes a first partition plate. The first partition plate is fixedly connected inside the heat exchanger. Gear rings are rotatably installed at equal intervals at the bottom of the first partition plate. Tubes are fixedly connected to the bottom of the gear rings.

[0010] Preferably, the filtration mechanism further includes a fixing ring. A fixing ring is fixedly connected to the outer side of the top of the rotating rod, and a scraper is fixedly connected to the outer side of the fixing ring. A rotating motor is installed inside the heat exchanger, and the output end of the rotating motor is fixedly connected to the rotating rod. The rotating motor drives the rotating rod to rotate, which in turn drives the fixed ring fixedly connected to the outer side to rotate. The rotation of the fixing ring drives the scraper fixedly connected to the outer side to rotate. During the rotation of the scraper, the surface of the filter plate is scraped to prevent clogging.

[0011] Preferably, the cleaning mechanism further includes a gear. A gear is fixedly connected to the outer side of the rotating rod, and the outer side of the gear meshes with a gear ring. A reciprocating screw is fixedly connected to the bottom of the rotating rod, and a moving block is meshed with the outer side of the reciprocating screw.

The rotation of the gear ring then drives the tubes fixedly connected to the bottom to rotate together. Simultaneously, when the rotating rod rotates, it drives the reciprocating screw to rotate, which in turn drives the moving block meshed with it to move. The movement of the moving block then drives the fixed ring fixedly connected to it to move.

[0012] Preferably, a first connecting rod is fixedly connected to the outer side of the movable block at equal intervals, and a fixing ring is fixedly connected to the other end of the first connecting rod. A steel brush is installed inside the fixing ring. During the movement of the fixing ring, in coordination with the rotation of the tube, the steel brush cleans the outer surface of the tube.

[0013] Preferably, the heat exchanger has symmetrical sliding grooves on its inner wall, and sliding blocks are slidably installed inside the sliding grooves. A movable ring is fixedly connected to one end of each sliding block, and a second connecting rod is fixedly connected to the inner wall of the movable ring, with the other end of the second connecting rod fixedly connected to the fixed ring. When the fixed ring moves, it drives the movable ring to move via the second connecting rod. The movable ring cleans the inner wall surface of the heat exchanger through the cooperation of the sliding grooves and sliding blocks.

[0014] Preferably, a second partition is fixedly connected inside the heat exchanger, and the rotating motor is electrically controlled by an external power source.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: the combination of filter plate, filter hole, rotating rod, fixed ring, scraper and rotating motor can filter and retain yeast, protein and solid residue in fermentation liquid, thereby improving the purity of ethanol; the combination of first partition plate, toothed ring, tube, gear, reciprocating screw and moving block can clean the outer surface of the tube, which can significantly improve the overall performance of continuous ethanol concentration device, remove scale, oil or material crystals attached to the outer wall, greatly reduce thermal resistance, and make the heat source energy more efficiently transferred to the ethanol solution in the tube, thereby reducing the consumption of steam or heat transfer oil and reducing the unit product energy cost.
