Fumigation gas circulation device for fumigation storehouse

Abstract

The invention discloses a fumigation gas circulation device for a fumigation storehouse. The device comprises the fumigation storehouse, an air supply pipeline, a circulating draught fan, an air returning pipeline and a pipeline cooling device. The air supply pipeline is arranged inside a side plate of the right end of the fumigation storehouse, one end of the air supply pipeline penetrates through the outer wall of the fumigation storehouse and is fixedly connected with the inner wall of the bottom end of the fumigation storehouse, the other end of the air supply pipeline is connected to an air supply port of the circulating draught fan through a flange, the circulating draught fan is fixed to the top of the fumigation storehouse, an air inlet pipe is arranged on a pipe body of the air supply pipeline, pipe bodies of the air inlet pipe and an air outlet pipe are all provided with Teflon sealing sleeve rings, the air inlet pipe and the air outlet pipe are symmetrically distributed around the center of the fumigation storehouse, the circulating draught fan is arranged at the upper end of the fumigation storehouse, the air inlet and an air outlet of the circulating draught fan are respectively connected with the air supply pipeline and the air returning pipeline, after the circulating draught fan is started, circulating flow is generated inside the fumigation storehouse to improve the reaction efficiency of drugs, and the gas does not leak out, thereby effectively reducing the environmental pollution.

Description

Technical field [0001] The invention relates to the technical field of fumigation silos, in particular to a fumigation vapor circulation device for fumigation silos. Background technique [0002] The fumigation warehouse is used to fumigate the wood before processing equipment. Wood fumigation can improve the quality of wood and facilitate processing and manufacturing. During the wood fumigation process, the fumigation warehouse must be treated with medicine to eliminate the pests and their eggs inside the wood. In order to make the drug reaction more uniform and full after administration, a gas circulation device is added to the fumigation library. However, the traditional gas circulation device is equipped with exhaust fans and blowers on both sides of the fumigation library to generate convection to promote the uniform reaction of the drug. After the gas containing medicine is discharged into the air, it causes pollution control, which does not meet the requirements of energy ...

Problems solved by technology

[0002] The fumigation warehouse is the equipment used to fumigate the wood before processing. The wood fumigation can improve the quality of the wood and facilitate the processing and manufacturing. During the wood fumigation process, the fumigation warehouse should be treated with chemicals to eliminate the pests and their eggs inside the wood. After dosing, in order to make the drug reaction more uniform and sufficient, a gas circulation device is added to the fumigation chamber, but the traditional gas circulation device is equipped with an exhaust fan and a blower on both sides of the fumigation chamber to generate convection to promote the uniform reaction of the drug. After the gas containing medicine is discharged into the air, it will lead to pollution control, which does not meet the requirements of energy saving and environmental protection, and the exhaust fan will soon stop working due to high temperature when extracting the heating gas inside the fumigation storehouse. gas circulation device
