Problems solved by technology

For example, tent fumigation is convenient, flexible, economical, and can adapt to various shapes and sizes of goods, but its disadvantages are also very obvious, such as low air tightness, and more leakage of fumigant agents, which is not safe for fumigation operators and can easily cause serious accidents. Environmental pollution, fumigation agents are difficult to distribute evenly, the fumigation effect is not guaranteed, the time of fumigation is long, and it

Embodiment Construction

[0027]Referring to Fig. 1, the operating mechanism of the fumigation system of the present invention is as follows: after the methyl bromide fumigant in the drug storage bottle 101 is metered by a metering device 102 (such as an electronic scale, etc.) and vaporized by a vaporizer 103, under the circulation effect of a circulation fan 104 , achieve uniform distribution in the fumigation storehouse 105 so as to achieve the purpose of airtight fumigation and insecticide for logs or wood; during this period, the concentration of methyl bromide is detected and recorded by the fumigation concentration automatic detection device to ensure the final fumigation effect and facilitate quarantine supervision; fumigation After the end, use the tail gas absorbing device 106 to absorb the remaining methyl bromide tail gas in the fumigation storehouse 105 to protect the environment, and then discharge the absorbed methyl bromide through heating and desorption for reuse or after harmless treatm...

Abstract

The present invention relates to one kind of fumigating system, which consists of several fumigating warehouses communicated mutually and with inside airtight space; one fumigant throwing unit communicated to all the fumigating warehouses, one fumigant gas path unit communicated to all the fumigating warehouses for forming one closed fumigant circulating path, and one fumigant exhausting and recovering gas path unit communicated to all the fumigating warehouses for forming closed fumigant recovering path. The fumigating system is for large scale log fumigation, and has excellent control performance, high automation, high efficiency, high safety and environment friendship.

Description

technical field [0001] The invention relates to a fumigation system, which is mainly used for large-scale quarantine and pest removal treatment of logs, wooden packages, furniture and other import and export goods, and can also be used for the treatment of harmful organisms (such as insects, bacteria, fungi, nematodes and miscellaneous Fumigation of other goods such as grass, etc. Background technique [0002] At present, on the one hand, with the rapid development of the economy, the domestically produced timber in my country is far from meeting the demand in terms of quantity and quality. Experts estimate that it will take at least 50 years to fundamentally reverse this situation. On the other hand, as the environment in the world is deteriorating day by day, people's awareness of environmental protection is constantly increasing. In order to protect the environment, it is necessary to reduce the felling of forest logs and maintain ecological balance. Therefore, in additi...
