Abstract

The invention relates to a device for preventing and treating insect damage through carbon dioxide. The device comprises a sealing tent, and storage materials are contained in the sealing tent; the periphery of the sealing tent is wrapped with a heat preservation and insulation layer; a gas inlet pipe and a gas outlet pipe are arranged on the two sides of the middle of the sealing tent respectively, one end of the gas inlet pipe and one end of the gas outlet pipe are located in the sealing tent, and electromagnetic valves are arranged at the other ends, located outside the sealing tent, of the gas inlet pipe and the gas outlet pipe; a heater is connected with a carbon dioxide gas source, and is connected with the gas inlet pipe, the gas outlet pipe and the sealing tent to form a sealing loop; a carbon dioxide sensor and a temperature sensor are installed in a membrane cover and is connected with a PLC arranged outside the membrane cover and used for controlling the electromagnetic valves; the PLC is connected with the heater. The invention further discloses a method for preventing and treating the insect damage through the carbon dioxide. The method for preventing and treating the insect damage through the carbon dioxide is simple in structure, convenient to use and good in insect killing effect. The method is short in insect killing time; insect killing is thorough; the method is safe, environmentally friendly and free of residues.

Description

technical field [0001] The invention relates to a storage insecticidal device and method, in particular to a device and method for controlling insect pests by utilizing carbon dioxide. Background technique [0002] At present, the main method for killing insects in storage materials such as tobacco leaves and grains is to use phosphine (PH 3 ) fumigation to kill insects. Although this method has obvious insecticidal effect, due to the highly toxic, flammable, and explosive properties of phosphine, it is easy to cause personnel poisoning or other safety accidents during the fumigation and insecticidal process, and it will also bring harm to the surrounding environment and humans and animals. Certainly dangerous. With the enhancement of people's awareness of environmental protection, the use of highly toxic fumigants such as phosphine in the tobacco industry will be gradually stopped. The low-oxygen controlled insecticide technology, which has the advantages of environmenta...
