Technical field
The utility model relates to the Waste Heat Recoveries in ethylene glycol production to utilize field, heat in specifically a kind of ethylene glycol production
Amount recycling recycling system.
Background technique
According to design requirement, it is cooling using mechanical type electric blower to take off butanediol column overhead gaseous phase materials；Firstly, going out de- fourth
The gaseous phase materials temperature of glycol column overhead is at 140 DEG C or so, and to carry out cooling needs major diameter fan, and noise is relatively bigger；Meanwhile
Power consumption increases, increased costs.Secondly, mechanical type electric cooling blower can not accomplish that intelligent speed-regulating operates, also can not just protect
Cooling material constant temperature is demonstrate,proved, system performance measure is in stability range；Meanwhile mechanical type electric cooling blower is using installing, sell
It is also more troublesome in terms of maintenance afterwards, it needs to be regularly maintained, time-based maintenance.
Utility model content
It is raw to provide a kind of ethylene glycol in order to avoid the waste of thermal energy, saving power consumption, reduction production cost for the utility model
Heat recovery recycling system in production.
The utility model is achieved through the following technical solutions: heat recovery utilizes system again in a kind of production of ethylene glycol
System, the de- butanediol tower including having feed pipe are connected by circulation in the de- butanediol tower reboiler on de- butanediol tower, pass through pipe
Line is connected to the treating column of de- butanediol tower bottom, at least one steam generation of de- butanediol column overhead is connected to by pipeline
Device,
The liquid outlet of each steam generator is connected with butanediol intermediate storage tank respectively, and each steam generator goes out
Steam ports is connected with heating exchange station in Methanol Recovery tower reboiler, purification dealcoholysis tower reboiler and factory respectively by pipeline.
As the further improvement of technical solutions of the utility model, the quantity of the steam generator is two.
Heat recovery recycling system in a kind of ethylene glycol production described in the utility model,
The electronic cooling blower of existing machinery formula is overcome in terms of process system operation and plant maintenance and power consumption cost
Deficiency, wherein steam generator can not only make thermal energy repeat recycle, reduce the load of boiler, reduce the steam of boiler
Output quantity has saved coal consumption, while eliminating electric fan and saving power consumption, substantially reduces production cost.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of heat recovery recycling system in a kind of production of ethylene glycol.
In figure: 1, de- butanediol tower, 2, de- butanediol tower reboiler, 3, steam generator, 4, feed pipe, 5, treating column,
6, butanediol storage tank, 7, Methanol Recovery tower reboiler, 8, purification dealcoholysis tower reboiler, 9, heating exchange station in factory.
Specific embodiment
To keep the purpose of this utility model, technical solution and advantage clearer, below by the technology to the utility model
Scheme is described in detail.Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not before making creative work
Obtained all other embodiment is put, the range that the utility model is protected is belonged to.
The technical solution of the utility model is described in detail with reference to the accompanying drawing.
Heat recovery recycling system in a kind of production of ethylene glycol, the de- butanediol tower 1 including having feed pipe 4, is followed
Ring is connected to the de- butanediol tower reboiler 2 on de- butanediol tower 1, and the purification of de- 1 bottom of butanediol tower is connected to by pipeline
Tower 5 is connected at least one steam generator 3 of de- 1 tower top of butanediol tower by pipeline,
The liquid outlet of each steam generator 3 is connected with butanediol intermediate storage tank 6 respectively, each steam generator 3
Venthole by pipeline respectively with Methanol Recovery tower reboiler 7, purification dealcoholysis tower reboiler 8 and factory in heating exchange station 9
It is connected.
Thick ethylene glycol material is entered in de- butanediol tower 1 by feed pipe 4, after de- butanediol tower reboiler 2 heats, gently
Component butanediol becomes gas phase by liquid phase at high temperature and is separated, and enters steam generator 3 through tower top outlet, takes off butanediol
Tower tower bottoms send to treating column 5 and carries out separation high-class product ethylene glycol, and the butanediol solution come out through steam generator 3 enters fourth two
Alcohol intermediate storage tank 6, the water inlet of steam generator 3 are continuously fed to desalted water, and desalted water becomes high after high-temperature material heats
Warm steam is used for heating exchange station 9 in Methanol Recovery tower reboiler 7, purification dealcoholysis tower reboiler 8 and factory.
Temperature in order to guarantee 3 liquid outlet of steam generator is constant, maintains the stability of system operation, the steam generation
The quantity of device 3 is two.It can be sent out in this way by the amount and steam for regulating and controlling the water inlet desalted water of each steam generator 3
Raw device 3 opens and closes quantity to control the temperature of butanediol solution.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation
Or replacement, it should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should be with the power
