Description

Technical Field

[0001] The utility model relates to the technical field of snow-making equipment, and more specifically, to a supercritical high-temperature snow-making system. Background Art

[0002] Traditional artificial snow-making methods include low-temperature spraying method, sheet ice crushing method, block ice crushing method, etc. Low-temperature spraying snow-making can only generate snowflakes when the ambient temperature is below -5°C. Affected by the ambient temperature, it is necessary to make snowflakes during the low-temperature period in winter or artificially reduce the ambient temperature to below -5°C. The usage conditions are limited, and it is more restricted by seasons and ambient temperature, with high energy consumption. The snow-making environment is extremely cold, and the experience is poor. The sheet ice or block ice crushing method is a method of crushing sheet ice or block ice and blowing it out with a blower, which will cause snowflakes to stick together and have a relatively high hardness, with a large difference from natural snowflakes, and also has high energy consumption.

[0003] In view of this, this application is specifically proposed. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is that traditional artificial snow-making methods need to make snowflakes during the low-temperature period in winter or artificially reduce the ambient temperature to below -5°C. The manufactured snowflakes are prone to sticking together and have a relatively high hardness, with a large difference from natural snowflakes. The purpose is to provide a supercritical high-temperature snow-making system that can make snow in a high-temperature environment above zero degrees, is not restricted by seasons and ambient temperature, has a fluffy snow-making form close to natural snow, provides a good experience, and at the same time has low snow-making energy consumption, is energy-saving and efficient.

[0005] The utility model is realized through the following technical solutions:

[0006] A supercritical high-temperature snow-making system includes a water source, a snowflake generating device, and a refrigeration device;

[0007] The water source is introduced into the water inlet passage of the snowflake generating device as snow-making raw material. The water source can be tap water, well water, or filtered lake water;

[0008] The refrigeration device includes a compressor and a condenser. After the compressor compresses the refrigerant and enters the condenser for cooling, the refrigerant is transported to the snowflake generating device to cool the water source introduced into the water inlet passage to form a mixture of snowflakes and water;

[0009] The outlet end of the snowflake generating device sprays out the mixture of snowflakes and water, and the water containing snowflakes is transported to the snow storage area through a pipeline.

[0010] The snow-making system of the present utility model can make snow in a high-temperature environment above zero degrees, without being restricted by seasons and environmental temperatures, etc. The snow-making form is fluffy and close to natural snow, with a good experience. At the same time, the snow-making energy consumption is low, energy-saving and efficient. The high temperature in this application refers to the high temperature relative to the need for sub-zero temperatures in existing traditional snow-making, that is, it refers to a temperature environment of above zero and twenty or thirty degrees in summer.

[0011] The supercritical state in the present utility model means that the water source is lowered to -1 to -3 °C by the snowflake generating device without freezing, and finally snowflakes are formed after the water flow is ejected, that is, the supercritical state refers to exceeding the critical temperature of the water solid-liquid conversion.

[0012] The snow-making process of the snow-making system of the present utility model is as follows: The water source is introduced into the snowflake generator, and the other side of the snowflake generator is circulated by a compressor, a condenser and a snowflake generating device for heat exchange to cool the water source. The outlet end of the snowflake generator ejects a mixture of snowflakes and water, which is then transported to the snow storage place.

[0013] In a specific embodiment, the water inlet passage of the snowflake generating device is a bundled spiral confluence channel, and an annular cold flow channel is coaxially arranged outside the bundled spiral confluence channel for the refrigerant to flow through. The front end of the bundled spiral confluence channel is in a bundled spiral structure, and the rear end is a confluence flow channel.

[0014] By setting the water inlet passage as a bundled spiral confluence channel with a bundled spiral structure at the front end and a confluence flow channel at the rear end, and at the same time setting an annular cold flow channel outside the water inlet passage, the present utility model can enable the refrigerant to fully exchange heat with the water source, thereby realizing the generation of a mixture of snowflakes and water.

[0015] In a specific embodiment, a fan-shaped vortex nozzle is arranged at the outlet end of the bundled spiral confluence channel of the snowflake generating device. Under the action of the fan-shaped vortex nozzle, the snowflakes and water in the snowflake and water mixture can be preliminarily separated, making the obtained snowflakes more dispersed and closer to the form of natural snow.

[0016] In a specific embodiment, a snow-making water pump is arranged between the water source and the snowflake generating device, and the water source is transported to the snowflake generating device through the snow-making water pump.

[0017] In a specific embodiment, the water source includes a storage pool, and a snow separation board for storing snow is arranged on the surface of the storage pool. The mixture of snowflakes and water ejected from the outlet end of the snowflake generating device is input onto the snow separation board through a snow transportation pipeline and accumulates. The snow separation board is evenly distributed with separation holes, and the density of the separation holes is less than the density of snowflakes, for separating snowflakes and water.

[0018] The utility model is provided with a water storage tank for storing snow-making water, and a snow isolation plate is arranged on the top of the water storage tank for storing snowflakes. The snowflake and water mixture made by the snowflake generating device is transported to the snow isolation plate for accumulation to form snowflakes, and the excess water passes through the separation holes and enters the water storage tank for recycling. After cyclic accumulation, the snow-making function is completed. Through the above structural arrangement, the utility model can recycle the water in the snow-making process. In addition, the water separated from the snow and returned to the water storage tank has a lower temperature, which can continuously cool the water source in the water storage tank, that is, the recycled water can pre-cool the subsequent water source, thereby reducing the temperature of the water source introduced into the snowflake generating device and reducing the energy efficiency of refrigeration.

[0019] In a specific embodiment, a water absorption filter and a snowflake remover are further arranged between the water source and the snowflake generating device. Among them, the water absorption filter is used to filter large-particle impurities in the water storage tank, and the snowflake remover is used to remove the snowflakes and fine particles falling from the isolation plate into the water storage tank to provide a cleaner snow-making water source.

[0020] In a specific embodiment, heat insulation layers are arranged at the bottom and around the water storage tank, and the heat insulation layers can keep the temperature of the water source in the water storage tank at a lower temperature without being affected by the external environmental temperature.

[0021] In a specific embodiment, the snow delivery pipeline includes an upper snow delivery pipeline and / or a lower snow delivery pipeline. The upper snow delivery pipeline transports the snowflake and water mixture from above the snow isolation plate, and the lower snow delivery pipeline extends into the water storage tank and passes through the snow isolation plate from bottom to top to transport the snowflake and water mixture. Through the upper snow delivery pipeline and the lower snow delivery pipeline, the snowflakes can be accumulated on the isolation plate from bottom to top or from top to bottom.

[0022] In a specific embodiment, electric control valves are arranged on both the upper snow delivery pipeline and the lower snow delivery pipeline, and one or more snow outlets are arranged at the snow outlets of the upper snow delivery pipeline and the lower snow delivery pipeline.

[0023] In a specific embodiment, a regulator is further arranged between the condenser and the snowflake generating device, and the cooling method of the condenser adopts air cooling or water cooling.

[0024] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0026] 2. The supercritical high-temperature snow-making system provided by the embodiment of the present utility model can generate a mixture of snowflakes and water by setting the water inlet passage as a bundled spiral structure at the front end and a confluent flow channel at the rear end, and simultaneously setting an annular cold flow channel outside the water inlet passage, enabling sufficient heat exchange between the refrigerant and the water source.

[0027] 3. The supercritical high-temperature snow-making system provided by the embodiment of the present utility model stores snow-making water in a storage pool, and a snow separation plate is arranged at the top of the storage pool for storing snowflakes.
