Description

Greenhouse ozone pipe network tapping equipment

Technical field

The utility model relates to the device that utilizes ozone to carry out the air sterillization sterilization, and especially a kind of device that in the greenhouse, discharges ozone is applicable to crops diseases prevention in the greenhouse, particularly high stalk crops sterilizing disease prevention.

Background technology

Ozone have do not induce the microorganisms pesticide resistance, but thereby the whole sterilization space of permeating rapidly makes the no dead angle of sterilization be converted into oxygen within a short period of time and do not produce and do not damage health, advantages such as the sterilization effect is good more in the environment of high humidity under secondary pollution, the normal condition; So especially be fit in the greenhouse carry out sterilization with ozone; Existing greenhouse ozone application technology is the nearly top discharge ozone from the greenhouse; The use blower fan diffusion that has, the use single conduit that has punching diffusion.In the reality, the greenhouse generally surpasses 2500 cubic metres, and the space is very big; Adopt single conduit punching delivery mode, its diffusion power is very little, adds the obstruction of plant; Diffusion length is bigger after discharging ozone, moreover the decomposition of ozone is very fast, and concentration can reduce in diffusion process; Thereby concentration gradient that need be bigger, if but be diffused into low concentration region to the ozone of high concentration region rapidly, will perhaps can not guarantee effect by damage to crops.In addition, the nearly top discharge ozone in the greenhouse is for plant such as romaine lettuce, the strawberry etc. of short life; Effect is pretty good, but for high culm plant such as tomato, cucumber etc., plant bottom protection effect is undesirable; Near surface place soil and plant are the important place of germ virus breeding increment, especially plant bottom in the greenhouse, and it is poor to ventilate; Illumination is few, and high humidity is susceptible easily; Germ quantity is increased severely, and at the nearly top discharge ozone in greenhouse in this case, also be the highest zone of ozone concentration at the youngest tender position of plant; It has limited the application concentration of ozone, and the maximum position of near surface place germ is the minimum place of ozone concentration on the contrary, has reduced effect more.

Summary of the invention

The utility model discloses a kind of greenhouse ozone pipe network tapping equipment that is applicable to crops sterilizing disease prevention in the greenhouse; It is little to solve in the existing ozone application technology ozone diffusion power; Required ozone concentration gradient is bigger; The bigger deficiency of diffusion length behind the discharging ozone strengthens the sterilizing disease-preventing effect of the relative multi-section of germ quantity positions such as near surface soil and plant bottom.

The technical scheme that the utility model adopted is: disclosed greenhouse ozone pipe network tapping equipment comprises time controller, ozone generator and escaper; Between power supply and ozone generator turn-on time controller; Escaper is made up of the release pipe network that comprises the person in charge and several branch pipes, and arm is connected with the person in charge, has several discharge orifice on the arm; Be responsible for and the arm endcapped, the input interface of escaper is located to be responsible for upward and with the gas outlet of ozone generator and is connected.The escaper pipe network can be positioned over ground, greenhouse, and the input interface of escaper places is responsible for the middle part, is responsible for to two ends and extends, can be according to crop row apart from arm be set, and arm is layed between crop row.Ozone generator is used to take place ozone, and time controller is used for according to the size in space, canopy chamber being set running time, and the discharge orifice on the arm is discharged into ozone gas between plant the escaper pipe network quickly and evenly between crop row through being layed in.In addition, the escaper pipe network of the utility model part can double as micro spray irrigation system.

The utility model adopts face of land pipe network discharging ozone mode, and the one, owing to increased arm, discharge orifice quantity is increased in large quantities, reduced the diffusion requirement of ozone discharging back greatly, evenly distribute immediately and onset after making the ozone discharging; The 2nd, ozone is emitted on the low level zone that needs most sterilization, and at the Lao Ye of the plant of these area distribution and cane etc., it is strong to tolerate the ozone ability; Be difficult for injured; When ozone was diffused into the plant top, concentration can reduce, and had reduced the infringement that the plant tender tissue is produced.Obviously, under this state, make that the ozone mean concentration in whole greenhouse is higher, distribution is more reasonable, protection effect is better, and is safer effective.This device little power consumption in addition, expense is low, once mounting be provided with after use throughout the year, simple to operate.

Embodiment

Below, in conjunction with accompanying drawing and specific embodiment the utility model is further described.

In the utility model is implemented; Shown in accompanying drawing 1, greenhouse ozone pipe network tapping equipment comprises time controller 2, ozone generator 3 and escaper; Between power supply 1 and ozone generator 3 turn-on time controller 2; Escaper is by the pipe network that comprises that the person in charge 7 and several branch pipes 9 are formed, and arm 9 is connected with the person in charge 7, has several discharge orifice 10 on the arm 9; The person in charge and arm are terminal with clamp 8 sealings, and the input interface 6 of escaper is located to be responsible on 7 and with the gas outlet 5 of ozone generator and is connected.
