Fumigation system

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...

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 is easy to be affected by the weather, etc.

Although fixed fumigation facilities, such as fumigation warehouses, are airtight to a certain extent and the fumigation effect is guaranteed after being equipped with corresponding equipment, they cannot be moved once built, and their applicability is relatively poor

Although the mobile fumigation box has good mobility flexibility, its fumigation volume is small and cannot meet the requirements of large-scale log fumigation
