Description
Technical field
The utility model belongs to grain depot sterilization and disinfestation device technique field, particularly relates to a kind of method of grain depot sterilization and disinfestation device and sterilization and disinfestation.
Background technology
In grain reserves process, in order to avoid grain goes mouldy and the generation of insect pest, for many years, China adopts chemical control Stored Product Pests, quick-acting due to it, convenient and economic dispatch feature is protected grain for science and has been made significant contribution, but also it should be noted that it technically with the limitation on ecology, as the resistance of insect to agricultural chemicals has the history of more than 70 year, over nearly 30 years, anti-organophosphor, organochlorine, the pest species of carbamate and pyrethroid increases to some extent, medicament residual toxicity and the harmful interference to the ecosystem, extensive concern and the attention of grain storage department are caused.Simultaneously healthy closely related not only with consumers in general of the quality of grain, is also related to grain security and the social stability of country.Due to the generation of microorganism excessive multiplication and disease and pest, grain loss in storage is also a no small numeral.
Utility model content
The technical problem of solution of the present utility model is just to provide that a kind of sterilization and disinfestation is effective, pollution-free to surrounding air, the grain depot sterilization and disinfestation device of grain non agricultural chemical residuum.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise sealing cover body, the bleeding point with pump-line is provided with above described sealing cover body, first wireway of side with first row pore is provided with below described sealing cover body, described first wireway is connected with carbon dioxide air source by the first valve, below described sealing cover body, be provided with second wireway of side with second row pore, described second wireway is connected with ozone gas source by the second valve.
Its additional technical feature is:
Described first wireway and the second wireway are relative " mountain " font, and the first conduit and the second conduit are alternately.
Grain depot sterilization and disinfestation device provided by the utility model compared with prior art, have the following advantages: one, owing to comprising sealing cover body, the bleeding point with pump-line is provided with above described sealing cover body, first wireway of side with first row pore is provided with below described sealing cover body, described first wireway is connected with carbon dioxide air source by the first valve, second wireway of side with second row pore is provided with below described sealing cover body, described second wireway is connected with ozone gas source by the second valve, pump-line is connected with the air regenerating device of grain depot, open air regenerating device, in negative pressure state in grain heap, then the first valve is opened, enter rapidly between grain gap at suction function carbon dioxide, make mushroom, worm's ovum, larva, adult is in oxygen-free environment state, breathe destroyed, bacterium and worm come to harm simultaneously within a certain period of time, sick body metabolism is not normal, then the carbon dioxide in grain heap is discharged, the high-concentrated ozone that ozone generator produces is inputted from the bottom to top below grain heap, utilize the strong oxidation of ozone to kill rapidly and be in ill all thalline and insects, ozone can become oxygen by disintegrate within a certain period of time under natural environment, so to environment, grain does not cause any pollution with residual, grain heap air gap volume after sealing is little, and main space is occupied by grain, therefore the carbon dioxide used in ventilation or ozone amount are also little.Ozone is gas simultaneously, and can permeate rapidly whole sterilized space, and sterilizing is without dead angle; Its two, because described first wireway and the second wireway are relative " mountain " font, the first conduit and the second conduit alternately, like this, carbon dioxide and ozone distribution more even, sterilization and disinfestation better effects if.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model grain depot sterilization and disinfestation device;
Fig. 2 is the top view that the first wireway and the second wireway are arranged.
Detailed description of the invention
Below in conjunction with accompanying drawing, the structure of the utility model grain depot sterilization and disinfestation device and use principle are described in further details.
As shown in Figure 1, for the structural representation of the utility model grain depot sterilization and disinfestation device, the utility model grain depot sterilization and disinfestation device, comprise sealing cover body 1, sealing cover body 1 adopts thickness to be the polyvinyl chloride film of 0.2 micron, the diaphragm seal of other materials can certainly be adopted, the bleeding point 3 with pump-line 2 is provided with above sealing cover body 1, the below of sealing cover body 1 is provided with side be connected with carbon dioxide air source 7 by the first valve 6 with the first wireway 5, first wireway 5 of first row pore 4., the below of sealing cover body 1 is provided with side and is connected with ozone gas source 11 by the second valve 10 with the second wireway 9, second wireway 9 of second row pore 8.Pump-line 2 is connected with the air regenerating device of grain depot, open air regenerating device, in negative pressure state in grain heap, then the first valve 6 is opened, enter rapidly between grain gap at suction function carbon dioxide, make mushroom, worm's ovum, larva, adult be in oxygen-free environment state, breathe destroyed, bacterium and worm come to harm simultaneously within a certain period of time, and sick body metabolism is not normal.Then the carbon dioxide in grain heap is discharged, the high-concentrated ozone that ozone generator produces is inputted from the bottom to top below grain heap, utilize the strong oxidation of ozone to kill rapidly and be in ill all thalline and insects, ozone can become oxygen by disintegrate within a certain period of time under natural environment, so do not cause any pollution with residual to environment, grain.
As shown in Figure 2, the first wireway 5 and the second wireway 9 are relative " mountain " font, and alternately, like this, carbon dioxide and ozone distribute more even, sterilization and disinfestation better effects if for the first conduit 5 and the second conduit 9.
Use above-mentioned grain depot sterilization and disinfestation device to carry out the method for sterilization and disinfestation, the method comprises the following steps:
Pass in ozone step in grain heap, the temperature in grain heap controls at 20-26 degree, effectively can extend the half-life of ozone at such a temperature, keeps the high concentration of ozone; Its four, owing to opening in the first valve step in described 3rd step, pass into carbon dioxide control time be 40---41 minutes, after closing the first valve and air regenerating device, maintain 70---72 hours, sterilization and disinfestation better effects if.
