AI Technical Summary
The existing condensers for wine making have a single import and export, resulting in a large accumulation of warm water, low thermal energy recycling value, and large cooling energy consumption, resulting in high production costs in the winery.
A three-pipe high-efficiency step heat recovery condenser is adopted, and the inner and outer shells form a cooling water cavity. The inner and outer heat exchange pipes are arranged coaxially, divided into high-temperature, medium-temperature and low-temperature cooling water areas. Water outlets are respectively set up to control the cooling water temperature range, and evenly distribute the cooling water through the water divider to prevent wine steam leakage.
The high-temperature effluent temperature is increased by 30-40℃, and the medium-temperature effluent temperature range is expanded, which reduces the power consumption of the cooling tower, improves the utilization rate of the warm water, and reduces the production cost of the winery.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of condensing equipment, in particular to a three-tube high-efficiency cascade heat recovery condenser. Background Art
[0002] Distillation is a traditional method for producing highly alcoholic beverages that dates back centuries. The basic principle of distillation is to use the physical properties of steam to separate liquids into alcohol and water. Since alcohol has a lower boiling point than water, when the liquid is heated, the alcohol first boils and converts to vapor, which is then cooled by a condenser and converted back into liquid. This process increases the alcohol concentration until it reaches the desired level for winemaking.
[0003] Existing cooling devices used in winemaking primarily utilize closed single-chamber cooling devices, which utilize a single cooling water inlet and outlet for heat exchange cooling. To ensure that the outlet water temperature meets the required winemaking temperature, the condensed water entering the cooling device is kept relatively low, resulting in a relatively low temperature for the warm water after heat exchange. Because there is only one cooling water outlet, the available warm water after heat exchange is approximately 50°C. When a winery has a high production volume, synchronous condensation also produces a large amount of warm water. However, due to the low quality of the water, the heat recovery value is low, the application scope is narrow, and the energy-saving benefits are low, resulting in a large amount of low-quality warm water accumulating in the winery. Most of this warm water is typically cooled and reused as condensate, requiring additional cooling towers. Cooling this large amount of warm water requires the cooling towers to operate at high load for extended periods, resulting in high cooling tower power consumption and significant heat waste. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the technical problem solved by the utility model is to provide a three-tube high-efficiency cascade heat recovery condenser to solve the problem that the existing wine-making condenser has only a single inlet and outlet, resulting in a large amount of warm water at the same temperature and high cooling energy consumption.
[0005] In order to solve the above problems, the technical solution adopted by the present invention is: a three-tube high-efficiency cascade heat recovery condenser, comprising an inner shell and an outer shell from the inside to the outside, a cooling water cavity is formed between the inner shell and the outer shell, the interior of the inner shell is a wine condensation cavity, the inner shell is provided with a plurality of outer heat exchange tubes along the vertical direction, the outer shell is provided with a plurality of inner heat exchange tubes along the vertical direction, the inner heat exchange tubes pass through the inner shell and pass through the middle of the outer heat exchange tubes, and the inner heat exchange tubes are coaxial with the outer heat exchange tubes; the shell is divided into a high-temperature cooling water zone, a medium-temperature cooling water zone and a low-temperature cooling water zone from top to bottom, the outer shell at the upper end of the high-temperature cooling water zone is provided with a high-temperature cooling water outlet connected to the cooling water cavity, the outer shell at the upper end of the medium-temperature cooling water zone is provided with a medium-temperature cooling water outlet connected to the cooling water cavity, and the cooling water inlet is provided at the lower end of the outer shell.
[0006] The beneficial effects of this solution are: by dividing the interior of the shell into three temperature zones according to the temperature after heat exchange, and then setting medium-temperature outlets and high-temperature outlets in the medium-temperature zone and the high-temperature zone respectively, the cooling water after heat exchange can be output in two different temperature ranges, the high-temperature outlet temperature range is 80-90℃, and the medium-temperature outlet temperature range is 60-65℃, so that warm water in different temperature ranges can be used separately; secondly, by discharging part of the warm water at the medium-temperature outlet, the amount of water entering the high-temperature cooling water zone is reduced, so that a higher outlet water temperature can be obtained after heat exchange in the high-temperature cooling water zone, which is 30-40℃ higher than the original one. The high-grade hot water can be used in a wider range, which improves the utilization rate of warm water stored in the winery; furthermore, the warm water at the medium-temperature outlet is recycled after cooling, the amount of water that needs to be cooled is reduced, the temperature difference for cooling is reduced, the power consumption of the required cooling tower is lower than before, and the production cost of the winery is reduced.
[0007] By controlling the medium-temperature water output, the wine temperature is controlled, ensuring the cooling water flow rate and heat exchange efficiency, thereby guaranteeing wine quality. The high-temperature water outlet ensures higher-quality recycled hot water. The entire system ensures higher-quality heat recovery water while also ensuring wine quality by regulating the medium-temperature flow rate. Furthermore, the double-layered tube configuration narrows the heat exchange space and increases the heat exchange area between the inner and outer heat exchange tubes, further enhancing the cooling effect of wine vapor.
[0008] Furthermore, a water distributor is provided at the lower end of the housing. The cooling water inlet is connected to the lower end of the water distributor, and a water outlet is provided at the upper end of the water distributor, which is connected to the cooling water chamber. By providing the water distributor at the lower end, the cooling water entering the cooling water chamber is diverted to both sides, thereby ensuring uniform distribution of the cooling water within the cooling water chamber.
[0009] Furthermore, the inner shell sequentially divides the wine condensation chamber into a steam separation chamber, a heat exchange chamber, and a wine collection chamber from top to bottom. The steam separation chamber is truncated cone-shaped, with a steam inlet pipe located at the narrow end of the cone and extending upward from the outer shell. The wine collection chamber is funnel-shaped, with the bottom of the funnel connected to a liquid outlet pipe, one end of which passes through the lower water cavity and extends out of the outer shell. The external heat exchange pipe is located in the heat exchange chamber, with its ends connected to the bottom plate of the steam separation chamber and the top plate of the wine collection chamber, respectively. The truncated cone-shaped steam separation chamber facilitates steam dispersion, and the funnel-shaped liquid collection chamber facilitates wine collection, allowing the wine to flow out of the liquid outlet in a concentrated manner.
[0010] Furthermore, the outer shell at the steam inlet pipe is provided with a sealing water ring. By adding water to the water ring for sealing, the air tightness of the device is ensured to prevent the leakage of wine vapor and affect the wine production. BRIEF DESCRIPTION OF THE DRAWINGS
