Description

Technical Field

[0001] The utility model relates to the technical field of phosphine tobacco fumigation and pest control equipment, in particular to a phosphine gas reaction device for fumigating tobacco pests. Background Art

[0002] Before being made into finished cigarettes, flue-cured tobacco is usually stored in a warehouse for a period of time, which is usually several years. During the storage process, tobacco pests cause serious tobacco losses every year. In order to reduce and prevent the loss of flue-cured tobacco, phosphine fumigation is usually used for prevention and control. At present, warehouses usually use phosphine fumigation equipment to produce phosphine, and then mix phosphine and carbon dioxide gas and send them into the warehouse to complete the insecticide operation in the warehouse. Phosphine is a gas that can kill pests generated by the reaction of aluminum phosphide and water. At present, the domestic public The equipment used for pest control in tobacco warehouses includes aluminum phosphide dosing devices and fumigators. The current dosing devices simply put aluminum phosphide into the reaction equipment in batches, and the feeding amount cannot be accurately controlled, which easily leads to waste of raw materials. Fumigators usually pour water directly on aluminum phosphide to react and produce phosphine gas. The speed and amount of water are difficult to control. The reaction between aluminum phosphide and water is more violent. If the water injection speed is too fast, the reaction speed in the equipment will be too fast, and a large amount of high-temperature and high-pressure gas will be generated immediately, which is easy to cause combustion and explosion.
