Vacuum nitrogen-charging and fumigating disinfection equipment and method

Abstract

The invention discloses vacuum nitrogen-charging and fumigating disinfection equipment and method. The equipment comprises a nitrogen generation unit, a humidifier, a vacuum pump, a disc heating type heater, a three-in-one sample injector, a disinfection box and a circulation fan, wherein the nitrogen generation unit is connected with the humidifier; the humidifier and the vacuum pump are connected with the three-in-one sample injector through a first pipeline; the disc heating type heater is connected with the three-in-one sample injector through a second pipeline; the three-in-one sample injector is also connected with the circulation fan connected with the disinfection box; the disc heating type heater is also connected with the disinfection box; a solid-liquid fumigant push rod is arranged in the three-in-one sample injector and connected with a pipeline plug located on the three-in-one sample injector. With the adoption of the vacuum nitrogen-charging and fumigating disinfection equipment and method, the nitrogen insecticidal efficiency can be improved, effective sterilization can be realized, the fumigating disinfection efficiency can be improved, the fumigant consumption can be reduced, and hazards caused by chemical fumigants to human bodies and environments can be avoided.

Description

technical field [0001] The invention relates to the technical field of disinfection of organic cultural relics, in particular to a vacuum nitrogen-filled fumigation disinfection equipment and a method thereof. Background technique [0002] Fragile organic texture cultural relics are the most serious type of cultural relics subject to natural degradation and environmental pest erosion and aging. Common insect pests in cultural relics involve 9 orders including Coleoptera, Isoptera, and Thysanoptera, and 29 families, with dozens of species; common molds include Aspergillus, Trichoderma, and Penicillium, etc. Hundreds of species. In 2005, the results of the "National Collection of Cultural Relics Corrosion Loss Survey" showed that the severe and endangered bamboo and wood lacquerware had a high corrosion rate of 48.68%, and a moderate corrosion rate of 21.11%. ; The severe corrosion rate of paper cultural relics reached 19.16%, and the moderate corrosion rate reached 35.02%. ...

AI Technical Summary

Problems solved by technology

[0004] (1) The temperature in the process of insecticide and sterilization cannot be controlled, resulting in long time and low efficiency of insecticide; (2) No circulation fumigation and low oxygen fumigation
