Snow maker with high snow making rate and control method and working method thereof

Abstract

The invention discloses a snow maker with a high snow making rate and a control method and working method thereof. The snow maker comprises a machine barrel, a draught fan, nozzles, gas-liquid nucleon devices, air nucleon devices, an air compressor, a temperature and humidity sensor, a flow regulating valve and a control module. The control module receives signals of the temperature and humidity sensor and controls the opening degree of the flow regulating valve through combination with the environment wet bulb temperature. According to the snow maker, the air nucleon devices are added to the rear ends of the nozzles and the rear ends of the gas-liquid nucleon devices, the air nucleon devices can make compressed air be throttled and expanded to a low temperature, nucleation of atomized water drops without nucleation is promoted, and nucleated ice particles can be promoted to rapidly grow into snowflakes. Compared with the prior art, the snow maker can effectively improve the snow making efficiency and quality of the snow maker.

Description

technical field [0001] The invention relates to the technical field of snowmaking machines, in particular to a high snowmaking rate snowmaking machine and its control method and working method. Background technique [0002] Artificial snowmaking equipment is mainly snowmaking machines. There are about 4,000 snowmaking machines in my country, including 3,500 imported snowmaking machines and only 500 domestic snowmaking machines. Weather data show that, on average, the global climate is warming. Winters are getting shorter and natural snowfall is falling. It is estimated that a 1°C increase in average temperature would shorten the ski season by about 25%. This means that the period of artificial snowmaking is longer, and the natural conditions of snowmaking are more harsh. At present, the global ice and snow industry is in a critical stage of upgrading and development. Especially with the Beijing Winter Olympics in 2022 and the realization of the goal of "300 million people...

AI Technical Summary

Problems solved by technology

Compared with European and American countries, my country's ice and snow industry started late. Although great progress has been made in recent years, there are still problems such as unclear understanding of snowmaking mechanism, backward technology and equipment, poor competitiveness of independent brands, and low industrial penetration rate.

[0003] The snowmaking efficiency and snowmaking quality of a snowmaking machine are mainly affected by environmental parameters and the atomization efficiency of nozzles and nuclear devices. One of the difficulties faced by snowmaking machines at present is that the water droplets ejected from the nozzles and the ice nuclei ejected from the nuclear device are inconsistent. With sufficient contact, part of the water droplets ejected from the nozzle cannot grow into snowflakes, resulting in a decrease in the snowmaking efficiency of the snow machine
