Example 3
The technical scheme of the invention is a grain storage tolerance treatment method, which adopts the grain storage tolerance treatment system described in the embodiment 2 and comprises the following steps:
in the ozone-free circulation mode, the axial flow fan and the power supply module are started, the power supply module outputs power in a first interval, and the axial flow fan circulates air in a grain warehouse; air in the grain warehouse sequentially enters an air inlet channel through an air inlet branch pipe and an air inlet pipeline, and coarse filtration and fine filtration are respectively carried out on the air through a first filter screen and a second filter screen; the filtered air enters a reaction module, a high-voltage electric field is generated by the power of an electrode wire in a first interval, high-energy electrons and ozone are generated by corona discharge, positive ions are accumulated on bacterial cell membranes in the air when the air passes through the high-voltage electric field, and electrolytes in the cells are destroyed; the negative ions and oxygen combine to generate negative oxygen ions to oxidize nucleic acid and protein structures of bacteria in the air; meanwhile, positive ions and negative ions are neutralized, high energy is instantaneously released, and the bacterial structure in the air is destroyed; the first ozone detector monitors the ozone concentration in the air outlet pipeline, and the control module regulates and controls the output power of the power supply module in the first interval power according to the ozone concentration information fed back by the first ozone detector, so that the ozone concentration in the air discharged to the air outlet pipeline is limited in a first threshold value;
in the strong ozone disinfection mode, the axial flow fan and the power supply module are started, the power supply module outputs power in a second interval, and the axial flow fan circulates air in a grain warehouse; air in the grain warehouse sequentially enters an air inlet channel through an air inlet branch pipe and an air inlet pipeline, and coarse filtration and fine filtration are respectively carried out on the air through a first filter screen and a second filter screen; the filtered air enters a reaction module, a high-voltage electric field is generated by the power of the discharge electrode wire in a second interval, and high-energy electrons and ozone are generated by corona discharge; the air rich in ozone enters each outlet branch pipe from the outlet pipeline, and the second ozone detector monitors the ozone concentration of the outlet of each corresponding outlet branch pipe; if the concentration of ozone fed back by the second ozone detector is lower than a second threshold value, the control module increases the valve opening of the second electromagnetic valve and decreases the valve opening of the first electromagnetic valve; if the concentration of ozone fed back by the second ozone detector is higher than a third threshold value, the control module reduces the valve opening of the second electromagnetic valve and increases the valve opening of the first electromagnetic valve; the third ozone detector monitors the ozone concentration of the air inlet pipeline, when the ozone concentration fed back by the third ozone detector is higher than a fourth threshold value, the control module reduces the output power of the power supply module, and when the ozone concentration fed back by the third ozone detector is lower than a fifth threshold value, the control module improves the output power of the power supply module.
In the above embodiment, the power of the first interval is smaller than the power of the second interval, and the higher the power output by the power module, the more ozone is generated by the reaction module.
In the above embodiment, when the strong ozone sterilization mode is finished, the ozone concentration in the grain warehouse is wanted to be reduced rapidly, and the ozone is electrolyzed by the discharge electrode line by reducing the output voltage of the power supply module, and the reaction principle of the reaction zone is as follows: O+O 3 →2O 2 ,O 3 +e -1 →O 2 +O+e -1 So that the staff can quickly enter the grain warehouse.
The reaction mechanism of switching to the ozone elimination mode after the strong ozone elimination mode is finished is as follows: when the strong ozone disinfection mode is operated, the output power of the narrow pulse power supply is high, oxygen in the air is directly ionized, and oxygen free radicals such as ozone are formed by ionization; after the sterilization is finished, the output power of the narrow pulse power supply is reduced, the power capable of ionizing ozone but not oxygen is achieved, the ozone is reduced into oxygen, and the effect of eliminating the ozone is achieved. It is well known that ozone is more active than oxygen, the bond energy of ozone is much lower than that of oxygen, and is more easily ionized, so that the power of the power supply is reduced, when the power is reduced to the level that oxygen is not ionized but ozone can be ionized, the ozone is ionized and decomposed into oxygen, and the purpose of eliminating ozone is achieved.
The grain storage-resistant treatment method has two operation modes, namely an ozone-free circulation mode and a strong ozone disinfection mode, wherein the ozone-free circulation mode aims at daily ventilation sterilization of a grain warehouse, and the strong ozone disinfection mode aims at deinsectization during pest outbreak of the grain warehouse. Under the synergistic complementation of the two modes, the grain warehouse can be in an ideal environment, so that the storage endurance of grains is improved.
