Device for automatically absorbing and recycling acetone

Abstract

The invention discloses a device for automatically absorbing and recycling acetone, which comprises an automatic absorption liquid replacement structure, the automatic absorption liquid replacement structure comprises an absorption liquid storage box, and the left side surface of the absorption liquid storage box is fixedly communicated with a liquid supplementing pipe positioned at the bottom end of the absorption liquid storage box; waste gas can be subjected to pre-absorption treatment through the pretreatment mechanism, the acetone content in the waste gas is reduced, the waste gas subjected to pre-absorption treatment can be blown into absorption liquid accumulated in the absorption reactor in the form of small bubbles through the gas distribution mechanism, the waste gas is promoted to make full contact with the absorption liquid, the purification effect is better, and the purification speed is higher; the device for automatically absorbing and recycling acetone is simple in structure, high in purification efficiency, capable of automatically replacing absorption liquid, high in automation degree, time-saving and labor-saving, capable of enabling tail gas to reach the standard by being independently used, free of being used in a combined mode, low in equipment cost, small in occupied area and high in practicability. The practicability of the device for automatically absorbing and recycling acetone is improved.

Description

technical field [0001] The invention relates to the field of equipment for recovering acetone in waste gas, and more particularly, to a device for automatically absorbing and recovering acetone. Background technique [0002] Acetone, also known as dimethyl ketone, is an organic compound with molecular formula C3H6O, the simplest saturated ketone, a colorless and transparent liquid with a slightly fragrant odor, soluble in water and methanol, ethanol, ether, chloroform, Pyridine and other organic solvents are flammable, volatile, and have relatively active chemical properties. They are mainly used as solvents in industry for explosives, plastics, rubber, fibers, leather, grease, paint and other industries. They can also be used as synthetic ketene, Important raw materials for acetic anhydride, iodoform, polyisoprene rubber, methyl methacrylate, chloroform, epoxy resin and other substances are also often used by criminals as the raw material for drugs. Bromopropiophenone is pr...

Problems solved by technology

[0003]The existing acetone recovery device is mainly composed of absorption tower, spray system, packing layer, etc. When in use, the exhaust gas enters the absorption tower from the bottom of the absorption tower and flows upward , the spray system sprays the absorption liquid from the top of the absorption tower, and then the absorption liquid contacts the acetone in the waste gas countercurrently, and then the acetone will dissolve into the absorption liquid and be removed, but the recovery device of this structure has low treatment efficiency and requires multiple Only when the recovery device is used continuously can the exhaust gas meet the standard, the equipment cost is high, the floor area is large, and it needs human control. A device for automatic absorption and recovery of acetone
