High pressure atomizing system is the use of high pressure atomizing host will be precision filtration treatment of water, transported to the fog special high pressure pipe network (pressure 14MPa), and finally reach the fog special nozzle spray into the fog system. The basic principle of the high-pressure atomizing system is that high-pressure water is ejected from the microhole and collides with the solid to form water fog, which is the basic principle of the equipment. The pressurized water will be atomized by a professional nozzle through a high-pressure pipeline, producing 0.10~15μm of micro fog particles, so that it can quickly absorb heat from the air to complete the vaporization and diffusion, so as to complete the purpose of air humidification and cooling.

peculiarity

· Fine fog: The high-pressure spray nozzle can produce 5 billion droplets per second, the diameter of the droplets is only 01-35μm, like a mountain of clouds, humidification and cooling effect is excellent.
 
· Energy saving: atomizing 1 kg of water consumes only 6W of power, which is one percent of the traditional electric humidifier and one tenth of the centrifugal or gas-water hybrid humidifier.
 
· Reliable: The main engine of high-pressure micro-fog cooling system adopts imported industrial crankshaft plunger pump, which can operate continuously for 24 hours. The nozzle and water mist distributor have no power vulnerable parts, and will not be damaged in high dust environment.
 
· Safe automatic pressure relief: When the sprayer stops working, the body will automatically release the pressure of the high-pressure nozzle to prevent the nozzle from dripping.
 
· Automatic water shortage and power failure system: prevent idling of pump when there is no water, improve pump life.
 
· Hygiene: The water of the high-pressure micro-fog system is sealed and non-recycled, which will not lead to the reproduction of bacteria.
 
· Spray volume: large spray volume and nozzle can be freely combined. The spray volume is stepless from 5kg/h to 2500kg/h. The spray efficiency is over 95%.


 
High pressure spray system is mainly used in facility agriculture cooling, humidification, plant protection and landscape. Among them, the facility greenhouse cooling according to the regional climate conditions, system investment, later maintenance costs, operating costs, cooling effect and the impact on the greenhouse humidity and other factors, to comprehensively consider the high-pressure spray system and other cooling methods to cool down, in order to achieve the best effect.
 

1. Cooling of facility agriculture

The greenhouse is a semi-closed system, which can reach a high temperature of more than 40℃ in summer, which seriously restricts the growth and development of crops in the greenhouse. Therefore, the high pressure spray system can be used to quickly and effectively cool the greenhouse, especially for the greenhouse with good ventilation and low relative humidity, supplemented by other cooling methods (such as sunshade net, ventilation), the cooling effect is better, and the temperature can be reduced by 3-8 ° C.
 
 
High-pressure spray cooling is suitable for well-ventilated greenhouses, using the principle of rapid evaporation and heat absorption of tiny droplets to cool down. The water is treated by the filtration system, pressurized by the high-pressure pump (greater than 4Mpa), and then transported to the special high-pressure atomizing nozzle through the pipeline of special materials for release, forming a fine fog drop below 15μm, which gradually permeates the entire greenhouse suspended in the air, rapidly evaporates and cools, and does not wet the ground. The cooling efficiency of high pressure atomizing is 95%, and the cooling efficiency of wet curtain fan is 80%, so the cooling effect of high pressure atomizing is better than that of wet curtain fan. Because of the small particles of high-pressure atomized droplets and the small water consumption, the possibility of crop morbidity is small. High pressure spray system needs booster pump and high pressure copper pipe, the investment cost is relatively high, the daily operation cost is high; Water needs to be filtered, otherwise it is easy to block the atomizing nozzle.

Second, facility agriculture humidification

The high-pressure spray system can increase the humidity through the micron level fine fog, which is specially used in seedling breeding, seed propagation, edible fungi and greenhouse planting, which can promote the rapid rooting of cuttings, improve the germination rate of seeds and the survival rate of tissue culture. Bai Ma Yuzhen et al. found in the comparative test of different seedling raising methods that spray cuttings in greenhouses had the highest survival rate, the fastest seedling growing speed and the best seedling growth.
 

Third, facility agriculture plant protection

After adding the appropriate concentration of drugs into the water tank of the high-pressure spray system, it can be atomized in the greenhouse, and the drug is sprayed evenly to effectively prevent and treat diseases and pests.
 
Fourth, facilities agricultural landscape
Large-scale multi-storey buildings or outdoor buildings with popular science, science and technology demonstration and sightseeing as the mainstream can use high-pressure spray system for landscape construction, which is loved by tourists.
