Summary of the invention
For the deficiency of existing green house demist wet down technology, the purpose of this invention is to provide a kind of comparatively simple demist wet down method.
To achieve these goals, the technical solution used in the present invention is:
A kind of green house defogging method comprises cavity body, and cavity body is the egg type body of the mid diameter semiclosed shape larger than two-port; The bottom of cavity body is communicated with collection bottle, and cavity body one end opening connects the air intake vent of fan blower, and the other end is as the droplet intake; Or cavity body one end opening connects the air outlet of fan blower as the intake of droplet, and the other end is as the air outlet of air-flow after filtering; Some metal gauze are set in the cavity, the filter cloth of aperture≤4 micron is set between metal gauze and the fan blower.The motor of fan blower is connected with civil power or storage battery, perhaps directly uses with the fan blower of gasoline as power.Cavity body is made by the iron sheet of aluminium alloy or stainless steel or painting.
Be engaged in for many years green house agricultural production peasant's experience according to south: humidity is too high in the booth, will form thick fog in the time of can producing harm.The fogdrop diameter of mist is generally all more than 3 microns.
Humidity is too high in green house, after forming thick fog, to contain the air of a large amount of droplets in the green house by filtering interception, droplet is on the increase in the space among a small circle at one, reach the concentration of condensing, the droplet constantly gauze in this little space or inwall condenses into water droplet and flows down, and enters collection bottle, thereby constantly reduce contained droplet in the interior air of green house, reduce the humidity of air in the green house.
The cavity body that two ends have smaller opening is set, cavity body one port connects fan blower, fan blower just forms negative pressure after starting in cavity body, the air that green house is contained a large amount of droplets is incorporated in the cavity from the cavity other end, flows out from fan blower again.Some metal gauze are set in the cavity, the filter cloth of aperture≤4 micron is set between metal gauze and the fan blower.After containing the end introducing of a large amount of droplet air by cavity, owing to the droplet of filter cloth aperture less than the overwhelming majority, droplet just is intercepted in the cavity, and the air behind the filtering droplet flow back in the green house through fan blower.Because droplet constantly is introduced in the cavity, the droplet of introducing can not be gone out from the other end again, greatly increased on the one hand the concentration of droplet in the cavity, the metal gauze of setting in droplet and the cavity and the collision opportunity of cavity wall have been increased on the other hand, a plurality of droplets will condense in together, form water droplet, water droplet flows into the following collection bottle that arranges along metal gauze or cavity wall under Action of Gravity Field.Like this, constantly the airborne droplet of green house is changed into the water in the collection bottle, the water in the collection bottle can pour into outside the green house, thereby reduces airborne humidity in the green house.By the continuous suction cavity to air in the green house, droplet constantly condenses in cavity, until the mist in the green house is all removed totally, greatly reduces the humidity of green house Air.
