Description

High-efficiency environment friendly distillation still
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.
Description of the drawings
Fig. 1 is schematic structural view of the invention.
Specific implementation mode
Present invention is further described in detail below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of high-efficiency environment friendly distillation still, including autoclave body, feed inlet 3, upper part discharge port 4, slag notch 5 and each Nozzle component;Autoclave body includes inner cylinder 1 and chuck 2, and chuck 2 is set to the outside of inner cylinder 1, cavity is formed between inner cylinder 1;Feed inlet 3 and upper part discharge port 4 be set to autoclave body top, slag notch 5 be set to autoclave body bottom;U-tube bundle heater is equipped on autoclave body 6, the U-tube bundle heat exchanger tube of U-tube bundle heater 6 is from the inner cylinder 1 that one end side wall of autoclave body lower half is extend into;Go out on top Material mouth 4 is equipped with filter device 8;Each nozzle component includes the steam blowing mouth 7 and hydraulic control mouth 9 being arranged at the top of autoclave body, is steamed Vapour blow valve port 7 and hydraulic control mouth 9 are connected to the inner cylinder 1 of autoclave body;Bottom temp meter interface is equipped on side wall of the autoclave body close to bottom 10;Slag notch 5 is trumpet type, and loudspeaker angle uses 30o.
The equipment performance is good, homogeneous heating, quickly, the finished product caprolactam low polymer-monomer qualification rate distilled out Up to 100%, meanwhile, sludge discharge is thorough, clean in kettle.
