Conveying device.
Background technique
The heat tracing of petrochemical industry pipeline and instrument pipeline, the heating of heavy oil tank field and dimension temperature, usual heating medium are
Low-pressure steam can give off a large amount of condensed water in high temperature and low pressure steam exhaust via steam trap, and direct emission will cause thermal energy
Waste with high-quality water resource and the pollution to environment will recycle it.In closed condensate recycling, steam
Drain valve more or less can all generate a certain amount of leakage vapour during the work time, while decompression process itself can be vaporized partially,
Cause condensate-water polishing conveying in Gas- liquid two-phase flow.Fluid in main line flows in the duct, hangs down when encountering from branch pipe
Histogram to fluid when, suddenly by bye-pass fluid bring resistance, fluidised form can occur change dramatically, cause main line fluid
Pipeline stress changes, and makes pipeline that sharp pounding or water attack, cavitation phenomenons occur, there are production safety hidden danger.The prior art
It is to be separated condensed water and steam exhaust by vapor-liquid separating device, liquid is conveyed by pump, and steam exists by pipeline
Electric power laying, pump fabricating yard be limited, equipment investment and plant maintenance problem, is often difficult to reality in the actual implementation process
It is existing, it is both inconvenient or not energy-efficient.
Summary of the invention
To solve the above problems, the utility model provides a kind of steam condensate and steam exhaust recycling mix conveying appliance, solution
Certainly condensed water and steam exhaust lead to the problem of sharp pounding in unpowered equipment transmission process, realize not only energy-saving and emission-reduction but also essence peace
Entirely.
The technical solution that the utility model solves above-mentioned technical problem is as follows：A kind of steam condensate and steam exhaust recycling mixing
Conveying device comprising inlet valve, heating coil, heated equipment, steam trap, bye-pass, main line, 90 degree of elbows and water conservancy diversion
Pipe, the inlet valve, steam trap, bye-pass, are sequentially communicated between 90 degree of elbows, diversion pipe and main lines the heating coil,
The heating coil is fixed in the heated equipment with welding manner.
As an improvement of the above technical solution, the bye-pass is inserted perpendicularly into the main line above the main line
It is interior, be connected by 90 degree of elbows with the diversion pipe with welding manner, the diversion pipe above the main line center line,
And it keeps being consistent with main line centerline parallel, opening direction with the main line fluid flow direction.
Further, the water conservancy diversion length of tube is 200~300mm.
Further, it is 4~16%, preferably 10% that the circulation area of the bye-pass, which accounts for the main line circulation area,.
As an improvement of the above technical solution, the heated equipment can be any in storage tank, pipeline, tower or container
One, and can multiple groups it is in parallel, share a main line.
The utility model has the beneficial effects that：Bye-pass is inserted into main line above main line, by 90 degree of elbows with
Diversion pipe keeps opening direction, and is consistent with main line fluid flow direction, can eliminate condensed water and steam exhaust recycling in nothing
Sharp pounding, water attack and cavitation phenomenons are generated when power transmission, are avoided damage pipeline and connected equipment, are accomplished both to save
Use is safe again for energy emission reduction, and facilitates implementation.
The above description is merely an outline of the technical solution of the present invention, in order to better understand the skill of the utility model
Art means, and being implemented in accordance with the contents of the specification, and in order to allow the above and other purpose, feature of the utility model
It can be more clearly understood with advantage, below in conjunction with preferred embodiment, and cooperate attached drawing, detailed description are as follows.
Detailed description of the invention
Fig. 1 is the flow diagram of the utility model；
Fig. 2 connect sectional view with main line for bye-pass；
Detailed description of the invention, 1. inlet valves, 2. heating coils, 3. heated equipment, 4. steam traps, 5. bye-passes, 6. supervisors
Road, 7. 90 degree of elbows, 8. diversion pipes, 9. main line center lines.
Specific embodiment
The utility model is further described with reference to the accompanying drawing, but the protection scope of the utility model is not limited to
It is as described below.
As depicted in figs. 1 and 2, blending transportation is recycled in a kind of steam condensate of the preferred embodiment in the utility model and steam exhaust
Device comprising 6,90 degree of inlet valve 1, heating coil 2, heated equipment 3, steam trap 4, bye-pass 5, main line elbows 7 and lead
Flow tube 8, the inlet valve 1, the heating coil 2, steam trap 4,5,90 degree of elbows 7 of bye-pass, diversion pipe 8 and main line 6 it
Between be sequentially communicated, the heating coil 2 is fixed in the heated equipment 3 with welding manner.
As an improvement of the above technical solution, the bye-pass 5 is inserted perpendicularly into the supervisor above the main line 6
In road 6, it is connected by 90 degree of elbows 7 with the diversion pipe 8 with welding manner, the diversion pipe 8 is in supervisor's Lu Zhizheng
9 top of line, and keep parallel with main line center line 9, opening keeps one towards with 6 fluid flow direction of main line
It causes.
Further, the 8 200~300mm of length of diversion pipe.
Further, it is 4~16%, preferably 10% that the circulation area of the bye-pass 5, which accounts for 6 circulation area of main line,.
As an improvement of the above technical solution, the heated equipment 3 can be appointing in storage tank, pipeline, tower or container
Meaning one, and can multiple groups it is in parallel, share a main line 6.
Unpowered blending transportation working principle：
The heating steam of certain temperature and pressure controls quantity of steam by inlet valve 1, flows through the heating dish in heated equipment 3
Pipe 2, it will release heat gives the cold medium in heated equipment 3, and partial condensation is discharged condensed water by steam trap 4 at liquid
Out, since vapour is leaked in the reduction of pressure and steam trap 4, it will a part of low pressure steam exhaust is generated, into bye-pass 5, in vapour phase band
Main line 6 is flowed into along low pressure direction under dynamic.Condensed water only accounts for the appearance of pipeline a part in 6 flow process of main line
Product, another part occupy for steam state, are in Gas- liquid two-phase flow.
6 internal flow state of main line is extremely complex, general more satisfactory situation be condensed water 6 tube bottom of main line in point
Laminar flow or wave flow, but the condensation water flowing when 5 fluid of bye-pass enters main line 6 below main line 6, in main line 6
For state by directly by the impact from 5 fluid of bye-pass, pipeline generates sharp pounding, at the same the fluid of main line 6 suddenly by
To resistance, original flow regime is destroyed, fluidised form disorder, and the variation of pipeline stress can also make the main line 6 generate vibration；?
When 5 condensed water of bye-pass imports main line 6,5 fluid of bye-pass is downwardly into main line 6 above main line 6, and is passed through
90 degree of elbows 7 and diversion pipe 8 export fluid along 6 flow direction of main line, can avoid water attack, engine knock and pinking occur existing
As.In addition, increasing entire 6 diameter of main line, it is possible to reduce resistance of the fluid in pipeline is conducive to that pipeline is overcome to shake.
Mill practices prove, pass through the transformation of this connection structure, it is ensured that use steam pressure, Jie in heat power equipment
In the case that too big variation does not occur for vacuum temperature and operating condition, condensate line will not generate apparent vibration, realize condensation
The blending transportation of water and steam exhaust in unpowered equipment.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
