A Recyclable Sulfuryl Fluoride Antivirus and Insect Removal System

Abstract

The invention discloses a disinfection and disinfestation system capable of recycling sulfuryl fluoride. The disinfection and disinfestation system comprises a disinfection and disinfestation unit with a working box and a gas storage tank for delivering the sulfuryl fluoride to the working box and further comprises a condensation recycling unit for conveying the condensed sulfuryl fluoride in the working box to the gas storage tank and a measurement and control unit for collecting and measuring the concentration of the sulfuryl fluoride in the working box. The disinfection and disinfestation system capable of recycling the sulfuryl fluoride is simple in structure, and starting and ending of the sulfuryl fluoride fumigating process and the recycling process of the sulfuryl fluoride are controlled through a PLC control system. The measurement and control unit can be utilized to control the concentration of the sulfuryl fluoride in the working box, wherein control over the fumigating concentration and the concentration before taking and after taking of the sulfuryl fluoride are included; on the one hand, the fumigating effect can be guaranteed, on the other hand, the safety performance of fumigation pieces in the taking and using processes of the fumigation pieces can be guaranteed. Furthermore, water vapor removal and condensation and recycling of the sulfuryl fluoride can be achieved at the same time through a cascade refrigerating machine.

Description

technical field [0001] The invention relates to a virus-killing and insect-killing system, in particular to a recyclable sulfuryl fluoride killing-virus and insect-killing system, which is used for harmless treatment of museum cultural relics. Background technique [0002] The main purpose of fumigation of cultural relics collections is to kill microorganisms and pests. Because the organic components in the cultural relics in the collection provide a large amount of rich nutrients and nutrients for the growth and physiological metabolism of microorganisms and pests, the degree of damage caused by microorganisms and pests to cultural relics is an extremely serious problem. Microorganisms decompose the proteins in organic cultural relics through the enzymes they decompose. At the same time, the secretions produced during the metabolic process seriously pollute the surface of cultural relics collections. [0003] Sulfuryl fluoride is a high-efficiency and excellent broad-spect...

Problems solved by technology

[0006] In addition, sulfuryl fluoride is a toxic chemical substance, direct manipulation is likely to cause direct skin contact of the staff, which is harmful to the operator's body, so the development of controllability is a very necessary direction

At present, for sulfuryl fluoride concentration measuring instruments with reasonable prices on the market, the working temperature range of the transmitter needs to be greater than or equal to -20°C.
