Description
Technical field
The present invention relates to core equipment-steamings in a kind of distillation still more particularly to a kind of Pa-6 Polymerization MONOMER RECOVERY device
Evaporate kettle.
Background technology
Currently, the enterprise of domestic chemical fibre industry production polyamide fibre 6, environmental protection consciousness enhancing, the extraction after being extracted to slice
Caprolactam low polymer-monomer is carried out recycling after polymerization again by water intaking no longer arbitrarily discharge by MONOMER RECOVERY device
It utilizes, had not only protected environment and carried out " zero " disposal of pollutants, but also can be enterprise to reduce cost of material, while the waste residue being discharged is through phase
After the processing of pass, low intensive engineering plastics can be manufactured.But the core equipment-of MONOMER RECOVERY high-purity monomer material system at present
Distillation still, distillation efficiency is not high, and general design structure is:Inner cylinder, chuck, feed inlet, upper part discharge port, slag notch and each
Nozzle component.
Invention content
Against the above deficiency, the present invention provides a kind of high-efficiency environment friendly steaming for caprolactam low polymer-MONOMER RECOVERY
Evaporate kettle.
In order to solve the above-mentioned technical problem, the present invention adopts the following technical scheme that.
A kind of high-efficiency environment friendly distillation still, including autoclave body, feed inlet, upper part discharge port, slag notch and each nozzle component;Autoclave body
Including inner cylinder and chuck, chuck is set to the outside of inner cylinder, forms cavity between inner cylinder;Feed inlet and upper part discharge port are set to kettle
The top of body, slag notch are set to the bottom of autoclave body;U-tube bundle heater, the U-tube of U-tube bundle heater are equipped on autoclave body
Beam heat exchanger tube is from the inner cylinder that one end side wall of autoclave body lower half is extend into;Filter device is equipped in upper part discharge port;Each pipe
Mouth component includes the steam blowing mouth and hydraulic control mouth being arranged at the top of autoclave body, the inner cylinder of steam blowing mouth and hydraulic control mouth and autoclave body
Connection;Bottom temp meter interface is equipped on side wall of the autoclave body close to bottom;Slag notch is trumpet type.
Further, slag notch(5)Loudspeaker angle be 30o.
A kind of high-efficiency environment friendly distillation still disclosed by the invention, operation principle are changed by chuck, U-tube bundle heater
Medium-steam in heat pipe heats the inside and outside of autoclave body inner cylinder simultaneously, by the caprolactam low polymer-in material
Monomer becomes gaseous state from mushy stage, and the gaseous monomer material distilled out is sent into monomer receiver by upper part discharge port;Waste residue is through loudspeaker
Type slag notch enters tapping equipment cooling, send to professional dirt recycling company processing.In this way, by Extraction For Pa 6 Chips
Later it is rationally recycled after effective ingredient caprolactam low polymer-monomer distillation, refinement in extract liquor, to reduce brocade
The production cost that synthetic fibre 6 is sliced.
The present invention increases U-tube bundle heater in autoclave body, and the material in inner cylinder is made to pass through chuck and U-tube bundle heater
Heat exchanger tube in medium dual-heated, can be rapidly heated, accelerate material decomposition rate;The steam blowing mouth added, is being opened
In docking process, steam is passed through by the nozzle, purges, remove the inner wall attachment of clean inner cylinder;The present invention is in upper outlet
Mouth is also additionally arranged filter device, and the monomer gas recycling of high-purity is effectively ensured;The hydraulic control mouth and bottom temp at the top added
Meter interface is matched with sensor electricity conference system, monitors the temperature of material liquid surface adjustable height and bottoms material in inner cylinder in time,
Feedback process data controls in inner cylinder the capacity of material and temperature within the scope of process stipulation;Bottom slag notch uses loudspeaker
Type structure, it can be ensured that waste residue thoroughly discharges.
Compared with the prior art, the advantages of the present invention are as follows:Both ensured that distillation still was quick, be evenly heated, and accelerated material point
Speed is solved, and medium liquid level, temperature in kettle are monitored in real time, convenient for periodic cleaning in kettle and detection convenient for user;Shortening carries
Refine the technique productions period of high-purity caprolactam low polymer-monomer.
