Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically to a heat exchanger for the brewing industry that prevents biological fouling. Background Technology

[0002] During distillation, a mixture of alcohol and water vapor is expelled from the distillation apparatus (such as a still or column). To obtain the final product (liquid), this alcohol-rich vapor must be effectively condensed. Condensation typically takes place in traditional equipment called an ice tank or in modern condensers. An ice tank is essentially a large copper coil immersed in a cooling medium (usually river water). In classic ice tank designs, river water is introduced directly into the ice tank pool, flowing around a spiral copper vapor conduit inside. The high-temperature, alcohol-containing vapor flows within the copper tubes, and heat is transferred through the tube walls to the pool water, causing the vapor to condense into liquid liquor. This process is highly dependent on a large amount of natural cooling water (river water), and its seasonal temperature fluctuations directly affect condensation efficiency (condensation is poor when the water temperature is high).

[0003] Traditional cooling methods suffer from microbial contamination problems: the traditional coil structure reduces thermal resistance and efficiency; the traditional water tank surface is sealed and there are many difficult-to-clean areas inside, leading to hygiene risks, product contamination, and potential equipment corrosion, as well as requiring frequent, time-consuming, and labor-intensive shutdowns for cleaning and maintenance.

[0004] Existing water tank equipment is prone to microbial growth due to sluggish water flow during long-term use, requiring frequent cleaning and exhibiting low heat exchange efficiency. Traditional cleaning methods also leave blind spots, making it difficult to thoroughly remove dirt and affecting the equipment's lifespan. Utility Model Content

The heat exchange plate is symmetrically arranged on both sides of the partition plate to form an S-shaped flow channel. The ends of the connecting pipes on both sides are respectively connected to the inlet tank and the outlet tank.

[0007] Furthermore: the water tank is symmetrically fixed with fixing rods inside, the upper end of the fixing rods is provided with a transverse guide rail, the guide rail is slidably connected to a slider, the upper end of the slider is rotatably connected to a rotating head, and the rotating head is provided with straps on both sides.

[0008] Furthermore: a drain outlet is provided at the lower end of one side of the water tank, a water pump is connected to the outside of the drain outlet, and a guide groove is provided on the inside of the drain outlet.

[0009] Furthermore, inclined platforms are provided on both sides of the heat exchange plate.

[0010] Furthermore, there are multiple heat exchange plates, and they are arranged with equal staggered spacing.

[0011] Furthermore: the strap is used to fix the cleaning water gun, and the rotating head and slider cooperate to achieve multi-angle cleaning.

[0012] Compared with existing technologies, it has the following advantages: the S-shaped flow channel formed by the heat exchange plate increases the water flow rate, avoids microbial retention, and reduces the number of cleaning times; the tilting platform breaks the thermal boundary layer and improves cooling efficiency; the slider and the rotating head work together with the strap to fix the cleaning water gun, achieving cleaning without dead angles; the guide groove improves drainage efficiency and prevents sewage residue.

[0023] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] like Figures 1 to 6 As shown, a biofouling-resistant heat exchanger for use in the brewing industry.

[0025] The device specifically includes a water tank 1. An inlet tank 6 and an inlet end 4 are fixed to one side of the interior of the water tank 1. An outlet tank 7 and an outlet end 5 are fixed to the other side of the interior of the water tank 1. A river water inlet end 3 and a river water outlet end 2 are respectively located on the lower side of the water tank 1. This is existing known technology and will not be described in detail here. A heat exchange mechanism is installed inside the water tank 1. The heat exchange mechanism includes a partition plate 8 fixed in the middle of the water tank 1. Heat exchange plates 9 are fixed on both sides of the partition plate 8. Multiple heat exchange plates 9 are arranged with equal staggered spacing, dividing the flow channel into an S-shaped configuration. Connecting pipes 10 are fixed to the upper sides of the heat exchange plates 9. Cooling water from the inlet tank 6 flows into the heat exchange plates 9 through the connecting pipes 10. The heat exchange plate 9 is welded together. Cooling water can flow smoothly into the heat exchange plate 9 through two connecting pipes 10. The heat exchange plate 9 is formed by welding two plates together to form a cavity channel. Cooling water flows inside, while hot water flows on both sides of the heat exchange plate 9. The cooling water exchanges heat with the hot water inside the water tank 1. The cooled water after heat exchange is pumped into the outlet water tank 7 for recycling. One end of the connecting pipe 10 is connected to the inlet water tank 6, and the other end is connected to the outlet water tank 7. This ensures that there are no water corners inside through the flow channel formed by the heat exchange plate 9, and the flow rate is increased to prevent microorganisms from remaining and growing inside, thus avoiding contamination of the entire water tank 1 and reducing the number of cleaning times. The upper part of the water tank 1 is completely exposed within the operating range, which increases the cleaning time and reduces downtime.

[0026] Inside the water tank 1, fixed rods 13 are symmetrically fixed. A horizontal guide rail 14 is fixed to the upper end of the fixed rods 13. A slider 15 is slidably arranged on the upper end of the guide rail 14. A rotating head 16 is rotatably connected to the upper end of the slider 15. Straps 17 are fixed on both sides of the rotating head 16 to fix the cleaning water gun to the straps 17. The rotating head 16 and the slider 15 can thoroughly clean the sewage and dirt inside the water tank 1. Since it is fixed by the straps 17, it can be moved up and down and left and right, which increases the cleaning range.

[0027] A drain outlet 12 is provided at the lower end of one side of the water tank 1. A water pump is fixed to the outside of the drain outlet 12 to pump water. A guide groove 11 is provided inside the drain outlet 12. The guide groove 11 can improve the movement of water flow, avoid sewage retention, and improve drainage efficiency.

[0028] Inclined platforms 18 are fixed on both sides of the heat exchange plate 9. The inclined platforms 18 can break the thermal boundary layer, thereby improving the efficiency of heat dissipation and cooling efficiency.

[0029] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
