Description

A kind of reactor high-temp high-viscosity blowing attemperator

Technical field

The utility model belongs to chemical production equipment field, further there is provided a kind of reactor high-temp high-viscosity and puts Attemperator is expected, for the discharging device of reactor in production processes of polyalcohol, mainly for high-temp high-viscosity material emptying mistake The blowing pipeline heat insulation of journey, prevents the new device of blowing pipeline frozen plug.

Background technology

Polymer processing field, partial reaction needs to complete at high temperature, when polymerization was complete, and blowing process just seems outstanding To be important, if the reduction of blowing temperature is too fast, material rapid condensation can be caused, drain hole is blocked so as to solidify.

In the prior art, it is ensured that drain hole is unimpeded following several method：Blowing is all ensured by dispensing speed first Mouthful, substantially quick blowing is equally that system is anti-in field of polymer technology, during blowing to avoid drain hole congestion The process answered, too fast blowing can cause material property to change, while the too fast pressure that can cause post processing of blowing is very big, it is right Equipment for after-treatment has requirements at the higher level.Another discharging method is that by electrical heat tracing mode, but this method can cause reaction The temperature difference of kettle and vomit pipe, part high molecular polymer performance during blowing can change.

In polymerization process, it is possible to the congestion of blowing link or failure occur, if material is not timely from reactor Release, material final performance can be caused to change, therefore there must be alternative during blowing, i.e., with changeable Material drain system, and the system possesses rapid exchange capabilities.

The content of the invention

The utility model provides a kind of reactor high-temp high-viscosity blowing attemperator, to solve existing polymer reaction During blowing pipeline heat insulation problem, the device applied in polymerization workshop blowing link, and conduction oil companion is to blowing pipeline Heat and jacket heat-preservation, it is to avoid high-temperature material solidifies during blowing, block blowing pipeline.Original fixed vomit pipe is designed to Changeable type vomit pipe, which such as there is pipeline putty, in production to be changed in time, accomplished that easy to operate, production is stable, changed convenient The features such as.

A kind of reactor high-temp high-viscosity blowing attemperator described in the utility model, including reactor, heating jacket, Vomit pipe, heat tracing pipe, baiting valve, transfer valve, delivery valve；Wherein, reactor is provided with heating jacket, its heating jacket and had Conduction oil, heats conduction oil by external device during the course of the reaction, makes conduction oil in heating jacket interior circulation, plays heating and rises There is the heat tracing pipe equipped with conduction oil, the S-type row of heat tracing pipe outside temperature effect, simultaneous reactions bottom end connection vomit pipe, vomit pipe Blowing pipe outer wall is listed in, complete coats vomit pipe；There is conduction oil to pass through transfer valve and delivery valve and reactor in heat tracing pipe Heating jacket connection, heat conduction oil temperature is made in reactor with heat conduction oil temperature in vomit pipe by control input valve and delivery valve Unanimously, it is ensured that be not in that cooling solidification blocks vomit pipe situation during blowing.

Good effect of the present utility model is：Reactor and vomit pipe use conduction oil interlayer structure, solve poly- During symphysis production blowing, because tube-cooled causes the process difficulties that drain hole is blocked, it is to avoid " production parking " may go out Existing risk.The blowing pipeline has quick-replaceable function, if vomit pipe replacing, behaviour can be carried out in 30 minutes by occurring blocking Make process simple, do not influence production, reduce enterprise's production cost, improve utilization rate of equipment and installations.

Brief description of the drawings

Fig. 1 is the utility model structural representation；

In figure：1 reactor, 2 heating jackets, 3 vomit pipes, 4 heat tracing pipes, 5 baiting valves, 6 transfer valves, 7 delivery valves.

Embodiment

The one embodiment described in detail below in conjunction with accompanying drawing

As shown in figure 1, the utility model include reactor 1, it is heating jacket 2, vomit pipe 3, heat tracing pipe 4, baiting valve 5, defeated Enter valve 6, delivery valve 7；The utility model during the course of the reaction, has conduction oil, in course of reaction in the heating jacket 2 of reactor 1 In by external device heat conduction oil, make conduction oil in the interior circulation of heating jacket 2, play heat temperature raising effect, simultaneous reactions The bottom of kettle 1 connects vomit pipe 3, and vomit pipe 3 is outer to have the heat tracing pipe 4 equipped with conduction oil, and heat tracing pipe is stainless steel, according to S Type is arranged in the outer wall of vomit pipe 3, and complete coats vomit pipe 3, and is wrapped up with insulation materials such as asbestos, plays insulation effect.Its All heating media of middle heat tracing pipe 3 are that identical reaction kettle 1 heats the same conduction oils, in reactor bottom, have two transfer valves 6, Delivery valve 7, makes in reactor 1 heat conduction oil temperature with heat conduction oil temperature one in vomit pipe 3 by transfer valve 6, the control of delivery valve 7 Cause, at the end of question response, open baiting valve 5, material is passed through and temperature of reaction kettle identical vomit pipe 3, it is smoothly flowed out Vomit pipe 3.Be not in that cooling solidification blocks the situation of vomit pipe 3 during guarantee blowing.

The vomit pipe 3 also has quick-replaceable function, if being occurred in that during blowing, vomit pipe 3 is blocked.It can close immediately Transfer valve 6, delivery valve 7 are closed, the bottom discharge valve 5 of reactor 1 is closed, quickly pulls down with heat tracing pipe 4, vomit pipe 3.Enable and carry The standby vomit pipe 3 of heat tracing pipe 4, opens transfer valve 6, delivery valve 7 after installing, make conduction oil rapid in the interior circulation of heat tracing pipe 4 Heating, opens baiting valve 5, continues blowing.
