Problems solved by technology

Chemical fumigation has a good insecticidal effect, but because the fumigant has certain toxicity, a large amount of use will bring safety and environmental problems
The low-temperature freezing insecticide method is costly and complicated to operate. During the heating and cooling process, the large temperature difference often leads to condensation on the surface of the object, or even mechanical damage, which is not conducive to the protection of cultural relics, books, and archives.
The low-oxygen insecticide method is safe and reliable, and uses the free gas diffusion method to replace and discharge the residual oxygen inside the collection, but the insecticide time is long and the work efficiency is low

Abstract

The invention discloses an airtight insect killing device and method. The airtight insect killing device comprises: a rigid airtight enclosure structure; a vacuum pump which is connected to the rigidairtight enclosure structure; a nitrogen source which is connected to the rigid airtight enclosure structure; a fumigant dispenser which is connected to the rigid airtight enclosure structure; and a controller which is configured to control the vacuum pump to reduce a pressure within the hermetic enclosure to a first pressure threshold. Besides, in response to the fact that the pressure in the airtight enclosure structure is reduced to the first pressure threshold value, the nitrogen source is controlled to fill the rigid airtight enclosure structure with nitrogen, or the fumigant dispenser iscontrolled to inject a fumigant into the rigid airtight enclosure structure. Compared with the prior art, the device is good in insecticidal effect, high in efficiency and convenient to operate.

Description

technical field [0001] The invention relates to insecticidal technology for articles such as cultural relics, books, archives, etc., and particularly relates to an airtight insecticidal device and method. Background technique [0002] Moth-eaten problems have always been an important factor that plagues the long-term storage of cultural relics, books, and archives. Chemical fumigation has better insecticidal effect, but due to the certain toxicity of fumigant, a large amount of use will bring safety and environmental problems. The low-temperature freezing insecticide method is costly and complicated to operate. During the heating and cooling process, the large temperature difference often leads to condensation on the surface of the object, or even mechanical damage, which is not conducive to the protection of cultural relics, books, and archives. The low-oxygen insecticide method is safe and reliable. It uses the free diffusion of gas to replace and discharge the residual o...
