Background technology

In the process of Chinese agricultural modernization, the industrialized agriculture selection that is inevitable, agricultural facility has significantly the use amount of increasing work efficiency, increase output, reduce agriculture chemical, makes full use of photo-thermal resource, precisely controls, anti-season cross-region ground constantly continuous production etc. be routine advantage.And various hot houses have been played the part of important role therein, hot house is take coating steel pipe as skeleton, transparent plastic sheeting is coverd with in outside, northern area is added a cover the heat-insulation layers such as straw screen or mat night in winter again, it is a kind of economic, practical, agricultural facility that income is good, the booth of China just constantly increases with very high growth rate at present, and in aquaculture, expands fast.No matter be kind to grow or aquaculture, booth practical application all can run into a problem, be exactly the temperature in summer canopy is very high, is unfavorable for the growth of animal and plant, even if used the measures such as sunshade, reflective membrane, temperature of shed toward contact more than 38 degree.At high like this temperature, can cause the poor appetite of some animals, feed intake reduces, and weightening finish is slowly even become thin.Resistance declines, and the incidence of disease increases, and some also can cause that heatstroke is even dead.Livestock and poultry food and not growing, has wasted a large amount of feeds, and feedstuff-meat ratio is declined to a great extent, and culture benefit declines and even occurs loss, and too high temperature also can cause the generation of plant multiple diseases and spread, and the wilting and poor growth of crop, bears fruit not good, yield reducation.Booth internal fan ventilates only can increase Air Flow, can not lower the temperature.Wet curtain requires good seal in whole building, and uses hard building materials.Air-conditioning power consumption is too large.Ground temperature utilization is still in the stage of fumbling, and up-front investment is excessive, and refrigerating capacity is limited.In recent years, a kind of cooling in summer method of high-pressure fog starts application, it is known starts from World Expo, at hot open deck spray cooling system, to visitor, left deep impression, its principle is in fact the same with warm curtain, be all to absorb the heat in surrounding air by the vaporescence of water, airborne temperature is declined.Being only mist cooling is that water under high pressure is ejected in air by spiral nozzle, become the fine liquid particles of several microns, the surface area of water has been increased many, make water fast vaporizing become possibility, because the particle of water is minimum, the effect of gravity is also little, water droplet is outstanding, and to stay the airborne time also longer, so these water particulates have time enough vaporization, can not form on ground water stain, because formed cold air can sink near ground, the temperature of the regional area on the earth's surface 3-8 degree that can decline.But there is a great deficiency in this high-pressure fog, the nozzle that is exactly shower nozzle is very little, generally at 0.1-0.3 millimeter, as unclean in water, be easy to stop up, while using in the bad area of water condition, can occur continuously the situation of not water outlet of multiple shower nozzle, greatly limited the use of this technology, therefore the filtration of water just becomes very important.In equipment in the past, normally in water inlet place, install multistage porous filter additional, intake pressure is produced by common water pump or tap water pipe line system, its pressure is less, generally only have 0.5-2.5 kilograms per centimeter, filter is once slightly stop up, it is large that the pressure reduction of Inlet and outlet water will become, the pressure loss of filter too conference makes hydraulic pressure loss totally, cause that water outlet reduces, insufficient water, if the anhydrous idle running of high-pressure hydraulic pump is easy to make it to damage, one of method that past solves is to install a set of booster pump additional to improve intake pressure, but this can increase again some equipment and expend many grid electricity fee costs, increase installation and maintenance expense, user feels uneconomical and inconvenient and is reluctant to use, other method is the rear end that filter is placed on to high-pressure hydraulic pump, although the loss of pressure is not a subject matter, because the hydraulic pressure in high-pressure hydraulic pump has 30-60 kilograms per centimeter ², high like this wiper seal and safety problem are just difficult to resolve certainly, and with after a period of time, filter screen still has the problem appearance of obstruction, and unpicking and washing high filter press cloth requirement will be high a lot.
