Abstract
The invention discloses a methyl alcohol gas absorbing method and device. Methyl alcohol gas enters a water washing tank from a methyl alcohol tank and is in contact with fresh water in a manner of water bath and spraying, so that methyl alcohol gas is absorbed in the fresh water to be discharged out of the water washing tank; a methyl alcohol gas pipe is communicated with the methyl alcohol tank and the water washing tank, and a fresh water pipe is communicated with the water washing tank. The methyl alcohol gas absorbing method and device are high in methyl alcohol absorbing rate, low in water consumption, simple in process and equipment, convenient to operate, and safe and reliable.
Description
Technical field
The invention belongs to and have at least a hydroxyl or oxygen one Metal Substrate to be connected to compound on the carbon atom of the ring except six-membered aromatic ring, particularly a kind of methyl alcohol aspiration receiving method and device.
Background technology:
The inflammable volatile polar liquid of methyl alcohol water white transparency.Sterling is ethanol smell slightly, and crude product is pungent unpleasant.Can with water, ethanol, ether, benzene, ketone and great majority other immiscible organic solvents.
Methyl alcohol belongs to medium malicious class material to all toxic effects such as health, nerve, skins.
To body harm: have anesthetic effect to have special selection index system to optic nerve and retina to central nervous system, cause pathology; Metabolic acidosis can be caused.
Acute poisoning: slight eye upper respiratory tract irritation appears in a large amount of suction in short-term, and oral have gastrointestinal irritation; Occur after incubation period a period of time headache, dizzy, weak, dizzy, feeling groggy, haziness,
delirium, even go into a coma.Optic nerve and PVR, can have blurred vision, diplopia etc., severe one is blind.
Occur during metabolic acidosis that carbon dioxide combining power declines, breathe and accelerate.
Chronic Effect: neurasthenic syndrome, vegetative dystonia, MMi, hypopsia etc.There is degreasing, dermatitis etc. in skin.
