Description

A kind of Device for producing snow

The utility model relates to a kind of device of refrigerating field, specifically is meant a kind of device of water being made people's system snow.

The method that early stage system snow adopts is earlier water to be made ice, and then will ice by pulverizing and make snow, and this method cost of manufacture is costliness and comparatively complexity, generally no longer employing at present of manufacturing process comparatively.The current snow making method that adopts in the world all is directly water to be made snow, its principle is earlier water to be broken into little water droplet by certain method, by certain method these little water droplets are lowered the temperature again, take away the heat of solidification of water, form core by certain method simultaneously, finally make these little water droplets form snowflake.

The system snow machine of current external development all is to adopt this principle to make, they are applied to outdoor skifield mostly as the equipment of mending snow, its system snow process is to utilize the injection of water under high pressure that water is broken into little water droplet and produces core, utilize the low temperature of nature and the heat of solidification that the low relative humidity environment is taken away water again, thereby produce snow.The domestic production that this class system snow machine is also arranged at present, as 508 research institutes of Beijing National Space Industry Corporation, they have just developed this outdoor system snow machine that is used on the basis of model machine abroad.This system snow machine is subjected to the constraint of applied environment condition, and it is had relatively high expectations to environment temperature and relative humidity, generally requires environment temperature to be lower than zero degree and relative humidity is lower, and its system snowfall is subjected to the influence of environment temperature and relative humidity.The system snow machine of this class can't be applied to indoor system snow, reason has 2 points: first, because it is the efficient of the wet exchange process of water and cold dry air heat is relatively poor, to its range with penetrate the certain requirement of Gao Douyou, therefore very big during this system snow mechanism snow to the area and the requirement for height of building.Second, this class system snow machine not only requires the dry-bulb temperature of air lower, and require the relative humidity of air also less, and in system snow process, because water constantly evaporates, the relative humidity of room air can constantly rise, and will make room air keep lower relative humidity, just need aid in a comparatively complicated and huge system equipment, and the cost cost is very high.

Goal of the invention of the present utility model be disclose a kind of simple in structure, make snow efficient height, be fit to the snow making apparatus of various conditions, occasion.

Realize that technical solution of the present utility model is as follows: cold liquid inlet tube connects a plurality of cold liquid outlets by pipeline, and the water under high pressure water inlet connects atomizer through pipeline, and atomizer places the middle position of a plurality of cold liquid outlets.Cold liquid and water under high pressure were sprayed respectively by cold liquid outlet and atomizer in the time of basic synchronization during use, water forms spray water after the atomizer ejection, simultaneously cold liquid ejection, produce local quenching environment, water smoke is rapid nucleation in this quenching environment, even form ice-nucleus rapidly, make again between the ice-nucleus and clash into and the bigger ice-nucleus of formation mutually, and then form snow at the mixing water smoke of two strands of vaporific gases in certain zone.

Of the present utility model simple in structure, make snow efficient height, snow making apparatus is changeable, can require the amount doesn't matter during installation according to actual environment, to satisfy different requirements, as be arranged on and make snow in the artificial ski field, can carry out local repair snow according to the situation of different location, the operation cost of skifield is reduced.

Provide most preferred embodiment of the present utility model below in conjunction with accompanying drawing.

Fig. 1 is the structural representation of a kind of embodiment of the present utility model.

Fig. 2 is the structural representation of another kind of embodiment of the present utility model.

Fig. 3 is the structural representation of the atomizer of band heater of the present utility model.

See also Fig. 1-Fig. 3, the concrete structure of embodiment of the present utility model is as follows, and cold liquid inlet tube 1 connects a plurality of cold liquid outlets 2 by pipeline, and water under high pressure import 3 connects atomizer 4 through pipeline, and atomizer 4 places the relative middle position of a plurality of cold liquid outlets 2; Described cold liquid can be liquid nitrogen, consider that the cold liquid of operating cost is liquefied air, not only reduce cost but also can be more suitable for affined relatively atmospheric environment in the artificial ski field, self cooling liquid outlet 2 ejections of cold liquid, basic water smoke simultaneously is by atomizer 4 ejections, water smoke forms ice-nucleus at the utmost point in the short time in vaporific cold liquid, and then collision forms snowmaking mutually.

In concrete use, because the shower nozzle of atomizer 4 part can touch vaporific cold liquid, so atomizer 4 is in lower temperature, can make shower nozzle local icing, or temperature is lower, resistance to water-flow in the atomizer 4 is increased, influence the atomizing effect of water under high pressure, for guaranteeing that atomizer does not freeze or temperature is low excessively, on the outer wall of atomizer 4, be provided with heater 5, the structure of heater 5 is one to have the tubular of through hole, the two ends of through hole have the connecting hole that connects atomizer 4 and inlet channel respectively, in barrel, be provided with in the more than one blind hole and insert heater element, when current through inlet channel again during heater via 5, current are heated, atomizer 4 is connected with heater 5 simultaneously, also can be heated to a certain extent, then can avoid atomizer 4 local freezing or the interior resistance to water-flow increasing of pipeline effectively, but described heater element heating wire rod, also ceramic heat rod.

Because artificial snow pack is had relatively high expectations to snow, as the size of granularity, the density of snow all has certain requirement, and the nucleation of its moderate snow is one of key wherein, for increasing the nucleation granularity of snow, the technical thought of employing is that secondary refrigeration and the mutual collision that increases the snow particle make it to increase granularity.Concrete technical scheme is that cold liquid outlet 2 is upper and lower settings, atomizer 4 occupy a plurality of relative middle positions of cold liquid outlet 2, at last cold liquid outlet 2 and atomizer 4 after the blink after the basic identical time ejection, down cold liquid outlet 2 sprays cold liquid again, the snowflake that makes nucleation is nucleation again, to improve the effect of secondary nucleation.Near down cold liquid outlet 2, be provided with air outlet 6, the snowflake that the wind of sending can increase nucleation under low-temperature condition holdup time and increase between the snowflake particle of nucleation the probability of collision mutually, this collision can form the snowflake of bigger nucleome, to satisfy the requirement of artificial snow flake to granularity and density; For further improving above-mentioned nucleating effect, air outlet 6 can be located at down the below of cold liquid outlet 2, and the outlet of air outlet 6 upwards, can make tentatively snowflake collision repeatedly under the effect of air-flow of nucleation, and increase the holdup time of snowflake in low temperature environment; Air outlet 6 also can be arranged on the identical horizontal level with down cold liquid outlet 2, and the Way out of air outlet 6 is identical with the Way out of down cold liquid outlet 2, and vaporific cold liquid is spread rapidly, makes low-temperature condition more even.For environment that artificial snow flake is formed more good.Be provided with the restriction cover body 7 of a under shed, the outlet of described cold liquid outlet 2 and atomizer 4 is all in cover body 7, when cold liquid and water ejection, the vaporific mixture of low temperature can be constrained in the cover body 7, not cause low temperature environment to spread disappearance rapidly, can increase the effect of nucleation, described down cold liquid outlet 2 and air outlet 6 are located at the under shed edge of cover body 7, particularly be that the time of nucleation and low temperature environment can be kept the quite a while when air outlet 6 during to up-draught, nucleating effect is better.

For the formation of snowmaking, also having a comparatively crucial problem is the atomizing effect of water.Water fog particle is too little too greatly all bad, and the density of too little snowflake is also little, increases the compacting workload of skifield, and also effect is slided in influence.Water fog particle is too big, be difficult to real nucleation in short time at the utmost point, therefore we have designed a kind of atomizer 4 of water, its structure is that interior pipe 8 and outer tube 9 are linked in together, form a cavity 10 between the front end of interior pipe 8 and the interior top of outer tube, be provided with seal 11 between interior pipe 8 and the outer tube 9, between the endoporus 12 of interior pipe 8 and above-mentioned cavity 10, be provided with side through hole 13 and inner via hole 14, endoporus 12 and cavity 10 are communicated, water can enter cavity 10 by above-mentioned passage, one hole for water spraying 15 is arranged on the top of outer tube 9, water is emitted into vaporific by hole for water spraying 15, because the inner passage is quite crooked complicated, under the effect of high pressure, current are a kind of disturbance state, and atomizing effect is better during ejection.Above-mentioned inner via hole 14 is a kind of helical form in the front end body of interior pipe 8, and this has increased disturbance state again, and is more smooth and easy when the ejiction opening for making water, is the flooding port 16 of a big expansion at the front end of hole for water spraying 15, can make the flow resistance of water littler and smooth and easy.
