Description
Technical field
The utility model belongs to chemical production technical field, specially a kind of sealing fluid cooling recirculation system.
Background technique
Currently, cyclohexanol device hydration reaction system uses desalted water degasser as the storage tank of sealing fluid and reaction water,
Pressurization is forced using a gear pump and provides sealing fluid to blender, thus inside and outside realizing that cooler envelope, balancing machine seal
Pressure, while tooth opinion pump also can provide reaction water to reactor.After being recycled in system due to blender sealing fluid finally again
It returns in desalted water degasser, this increase the temperature in the desalted water degasser as storage tank can in 3-4 hours, in this way
Corresponding gear pump temperature will be made to increase and cause to jump vehicle phenomenon.
The problem of being increased based on the system temperature in above-mentioned apparatus, staff replace a cyclohexanol using 3 hours
Sealing fluid in device hydration reaction system solves the problems, such as that sealing fluid temperature increases this, but since displaced water can only show
Field discharge, so that sealing fluid (cooling desalted water) serious waste, this virtually increases the cost of process units；And when operation
Staff's inspection is not in time and when blender sealing fluid failure will lead to the envelope damage of blender machine, so that blender is damaged,
And densification will occur when no blender stirs for hydration catalyst, will will lead to hydration catalyst calcellation when serious.
Summary of the invention
Utility model aims to solve above-mentioned sealing fluid temperature easily to increase, scene discharge waste is serious, sealing fluid
Utilization efficiency is low, staff has found not in time and solves the problems, such as failure to cause a series of damages, provides a kind of close
Sealing liquid cooling recirculation system.
The technical scheme in the invention for solving the technical problem is:
A kind of sealing fluid cooling recirculation system including sealing flow container, gear pump, cooler and is arranged in double on blender
End face machine envelope, the upper and lower of end seal side are respectively arranged with inlet and liquid outlet；The sealing flow container goes out liquid
Mouth is connected to the inlet of the end seal by gear pump, and the liquid outlet of the end seal is connected by cooler
To the inlet of sealing flow container.
End seal includes stationary ring sealing and two contact faces of ring seal, and rotating ring, stationary ring end face are mutually close
Fitting, and one layer of very thin liquid film is maintained in minimum gap between both ends of the surface, to achieve the purpose that sealing.End seal
There is twice end face seal, if primary seal fails, secondary seal is still salable, prevents from leaking.And it is supplied to outside double seals
Sealing fluid system introduces sealing fluid into seal chamber and is blocked, lubricated and cooled down, relates generally to recycle in the utility model cold
But.Sealing fluid inside end seal can not only improve the working environment of end seal, can also further judge one
Whether grade sealing surface fails.
A kind of working principle of sealing fluid cooling recirculation system described in the utility model is: being provided in sealing flow container close
Sealing liquid is pressurizeed by the gear pump and send the sealing fluid to the end seal of blender, and the sealing fluid is from setting
Inlet below end seal side is arranged from it in end seal after entering the cavity of the end seal
Liquid outlet discharge above side, the higher sealing fluid of the temperature of discharge are flow back into the sealing flow container by cooler, until
This working cycles terminates.
Preferably, the sealing flow container is provided with liquidometer.The sealing flow container peripheral hardware sets liquidometer can be in order to correlation
Staff observe at any time sealing flow container inside sealing fluid number, to add sealing fluid in time.
Preferably, be provided with valve on two connecting lines of the sealing flow container and liquidometer, the cooler with
It is provided with valve between sealing flow container, is provided with valve between the gear pump and sealing flow container.In the sealing flow container and the liquid
Setting can guarantee to keep communicating between sealing flow container and the liquidometer there are two valve between the meter of position, in the utility model institute
Valve is added between the distinct device in a kind of sealing fluid cooling recirculation system stated can close valve when overhauling this system
Close the specific place for finding leakage so as to quick timesaving.
Compared with prior art, the utility model has the beneficial effects that
(1) it reduces gear pump and jumps the probability of vehicle because sealing fluid temperature is excessively high, closing due to machine envelope when going into operation and adjusting
Formula circulation, operator do not have to frequently to realize cooler envelope, balancing machine sealing external and internal pressure to Field adjustment, guarantee
The even running of hydration reaction stirring system reduces the probability of stirring system failure；
(2) sealing fluid recycling efficiency is improved, the operating cost of process units is reduced, is reduced between device
Connect economic loss；
(3) sealing fluid and reaction water separate, so that reaction water purity improves, facilitate the raising of reaction conversion ratio, simultaneously
The resource consumption of process units largely declines, and production cost significantly reduces, and has apparent economic benefit.
