Description
The technical field is as follows:
the invention belongs to the technical field of tobacco processing, and particularly relates to an external hanging sterilization, disinfection and deinsectization integrated treatment device and method for a combined air conditioning unit suitable for a cigarette factory.
Background art:
the epidemic situation of the global 'new crown' pneumonia is developed in 2020, which has a great influence on all countries in the world. The currently determined novel coronavirus transmission paths mainly include direct transmission, aerosol transmission and contact transmission, so that people pay more attention to the safety of a ventilation system, and a central air-conditioning system even becomes a questionable virus transmission path. Most of ventilation air-conditioning units in the current market do not have a sterilization function. Some air conditioning units adopt an ultraviolet sterilization mode, an ultraviolet emitter is arranged at the position of an air duct inside the air conditioner, and the purpose of sterilization and disinfection is realized by irradiating airflow passing through the air conditioner with ultraviolet rays. The ultraviolet sterilization device is simple but low in sterilization efficiency, and various accessories in the air conditioning unit are easily influenced by ultraviolet radiation, so that a high-power ultraviolet emitter cannot be configured, and the irradiation with low power in a short time cannot realize effective sterilization. In addition, an air conditioning unit adopts a heating sterilization mode, and air is sterilized by heating a heat exchanger to 55 ℃ for a plurality of minutes. The temperature of the sterilization mode is low, and the inactivation of bacteria and viruses cannot be realized, particularly, the infection of the viruses can be effectively reduced only by heating the novel coronavirus at 56 ℃ for 30 minutes, and the complete inactivation of the viruses cannot be realized. The current workshop sterilization and disinfection measures in the tobacco industry are to manually spray disinfectant. The steps are complicated, the working efficiency is low, and certain potential safety hazards are brought to operating personnel.
The tobacco beetles are main pests in the cigarette factory, and the temperature and the humidity in a production workshop and a warehouse of the cigarette factory are higher, so that the tobacco beetles are suitable for growth and propagation. With the continuous transportation of tobacco leaf raw materials in production and the continuous entering and exiting of personnel in workshops, tobacco beetles in production workshops and alcoholization warehouses of cigarette factories are continuously propagated, and flue-cured tobacco insect pests cause serious economic loss and seriously threaten the quality of cigarette products. The main method for preventing and controlling tobacco beetles in production workshops and warehouses of cigarette factories is to spray chemical pesticides in the air or perform retention spraying on the floor, walls and equipment of the workshops. In order to reduce losses, the most common mode used in cigarette factories is to fumigate the smoke with phosphine for control. The phosphine fumigation equipment is adopted to generate phosphine, the phosphine and carbon dioxide gas are mixed and then sent into a workshop to realize the aim of disinsection in a warehouse, and the aim of disinsection can be realized only by maintaining the concentration of the phosphine in the smoke box at more than 200 or 300PPM for a certain time during the whole fumigation time. Traditional fumigation equipment structure is complicated, the volume is huge, needs artifical propelling movement to fixed position when using at every turn, and it is not convenient to remove and use. And conventional fumigation equipment can not realize accurate control of fumigation temperature, the risk of phosphine combustion and explosion is easily caused by overhigh temperature, and the fumigation effect is influenced by overlow temperature. Some cigarette factories place loose or packaged phosphide at a designated position of a workshop or a warehouse, and the phosphide naturally contacts with water vapor in the air to slowly react to generate phosphine so as to achieve the insecticidal effect. In rainy days or the condition of overhigh water vapor on the ground, phosphide easily reacts with moisture to generate excessive phosphine gas, thereby bringing potential safety hazard.
Therefore, how to utilize the air conditioning unit to realize safe, reliable, efficient and automatic indoor sterilization and disinsection is a problem to be solved urgently at present. The existing combined type of the workshop is reformed, the reforming cost is high, and the cigarette production is also influenced, so that an external hanging type sterilization and disinfection and insect killing method suitable for the existing combined type air conditioning unit needs to be developed.
