A system and method for making artificial snow using liquid nitrogen

Abstract

The invention discloses a system for making snow artificially by utilizing liquid nitrogen. The system comprises a gas way system, a liquid nitrogen system, a water way system and snow storage space; the gas way system, the liquid nitrogen system and the water way system are all connected with a snow making gun through pipelines, wherein the gas way system comprises a gas source, a first valve and a first pressure gauge; the liquid nitrogen system comprises a liquid nitrogen source, a second valve and a second pressure gauge; the water way system comprises a water source, a third valve and a third pressure gauge; the temperature in the snow storage space is kept constant; a water connecting opening, a gas connecting opening, a liquid nitrogen connecting opening and a jetting end are formed in the snow making gun; the water way system is connected with the snow making gun through the water connecting opening; the gas way system is connected with the snow making gun through the gas connecting opening; the liquid nitrogen system is connected with the snow making gun through the liquid nitrogen connecting opening; and the jetting end of the snow making gun is placed in the snow storage space. The invention also discloses a method for making the snow artificially by utilizing the liquid nitrogen. The system and the method have the beneficial effect that the snow can be made stably and highly effectively in any environment.

Description

technical field [0001] The invention relates to the technical field of artificial snowmaking, in particular to a system and method for artificial snowmaking using liquid nitrogen. Background technique [0002] At present, there are two types of artificial snow machines on the market: the first is that the ice making device produces flake ice, and then uses the flake ice as raw material to make snow. Its working process is that water is made into flake ice through the ice making device first, and then the flake ice that has been made is crushed into powder through the ice crushing device, and finally, the powdered ice crystals are sent out through the air conveying system. The snowmaking system of this method is complicated, and the quality of the "snow" produced is far from that of natural snow; [0003] The other is to use the artificial snow machine to use the principle of snowflakes falling, mix water and air under suitable conditions to make snowflakes, and use them in ...

AI Technical Summary

Problems solved by technology

But the problem is that the smaller the fog droplets, the greater the evaporation, the more water loss, and the lower the snowmaking efficiency

In addition, it can only work in an environment with a temperature below -3°C, and is highly dependent on the temperature of the external environment, which limits the application area and time of the snow gun

[0004] In addition, although there are already a large number of artificial snowmaking machines on the market, they basically cannot meet the high-efficiency artificial snowmaking in the high-temperature environment in summer, and the existing artificial snowmaking machines have average efficiency and can only meet the needs of ordinary amusement parks. However, large-scale international ski competitions need to produce a large amount of high-quality snow in a very short period of time. The above two snowmaking technologies are difficult to meet their needs.
