Description
Technical field
The present invention relates to grain-keeping equipment technical field more particularly to a kind of grain fumigatings reducing desinsection gas residue
Device.
Background technology
It is affected by many factors during foodstuff preservation, grain storage insect pest phenomenon often occurs, every year because grain goes mouldy
And loss accounts for very big proportion caused by insect pest etc., if effectively not controlling and killing these reserves pests, can not only cause grain storage
A large amount of losses, can also seriously affect the quality of grain storage, harm is very big.Therefore, during foodstuff preservation, it is necessary to be had
The control of effect simultaneously kills grain storage pest.
The main means of prevention grain storage insect pest now are to carry out fumigant insect killing using chemical fumigation method, and chemical fumigation method is to adopt
A kind of technology of grain storage pest, germ etc. is killed in closed grain storage warehouse with chemical fumigant, it can be promptly extensive
Annihilate pest in ground.The chemical fumigant that is mainly used in grain storage field in the world is hydrogen phosphide at present, hydrogen phosphide be it is a kind of it is colourless,
Hypertoxic, inflammable gas, its diffusivity is good, volatility is good, is easy to permeate to grain heap lower layer, is a kind of of good performance stifling
Agent is widely used in the daily insecticidal operation of grain storage enterprise of China.But large storehouse is after fumigant insect killing, usually
By the way of emptying naturally or machinery emptying, phosphine gas is not easy to be discharged, and the hydrogen phosphide residence time is long, and air is long in silo
Time cannot reach safety standard, extend fumigation time, simultaneously because the hypertoxicity of hydrogen phosphide, residual gas can be to environment
It causes to seriously endanger with human body.
Invention content
In view of this, the application provides a kind of grain fumigating device reducing desinsection gas residue, it is smoked to solve existing grain
