Wherein, between ozonator 4 and gas-liquid mixing pump 7, check valve 6 is housed.
Wherein, between ozonator 4 and oxygen cylinder 1, be provided with air relief valve 2 and oxygen flow meter 3.
Wherein, between ozonator 4 and check valve 6, be provided with ozone effusion meter 5.
This utility model is simple in structure, with low cost, produces and sprays the high-concentration ozone water with disinfection effect, directly acts on crop surface, can reduce pesticide dosage and disease prevention and control cost, effectively the disease in prevention and control production.Compare background technology, the utlity model has following advantage:
1, compared with chemical method control, Ozone Water has the bactericidal action of broad-spectrum high efficacy, nontoxic to human body, and ozone can be decomposed into oxygen voluntarily, does not produce residual contamination, harmless to crop growth.
2, this utility model is when ozonator is prepared ozone gas, adopt oxygen cylinder oxygen supply, can effectively improve the concentration of gas outlet ozone gas, be beneficial to produce high-concentration ozone water, and then the ozone steam of formation high concentration, directly act on crop surface, there is good disinfection effect, and in gas, the harmful substance such as nonnitrogenous oxide, safe and reliable.
3, this utility model utilizes gas-liquid mixed pump installation, substitutes traditional aeration and carries out gas-liquid mixed, has improved the dissolubility of ozone, and then has improved disease control effect.
