Description
Technical field
The present invention relates to a kind of transporting system, be specifically related to a kind of double fluid to steam transmission system.
Background technique
At present, steam is carried common direct-buried steam pipeline and built on stilts layout.Lay long defeated steam line between the each enterprise in garden time, can run into the many and various landform restrictions of obstacle.How complying with different terrain, is the problem that needs solve by steam line safety, laying smoothly.Steam line will solve the compensation, insulation of steam line, the problem such as hydrophobic according to different terrain.Because steam line needs to check, maintenance, there is potential safety hazard significantly in the steam line of direct-burried.Beyond steam line extends to plant area, the landform running into can more complicated.
Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide a kind of double fluid to steam transmission system, realize the double fluid of steam to regulating and balance, can ensure safe, efficient, the long-term operation of steam pipe line.
Double fluid of the present invention is to steam transmission system, comprise that steam generating system and steam use system, each steam generating system and steam use system include steaming device and main steam header road, steaming device connects main steam header road, and all steam generating systems use the steaming device of system to be connected by main steam header road with steam.
Steam generating system is the device that produces steam in actual production process, and if oxidation reaction is strong exothermal reaction, phthalic anhydride, maleic anhydride production device have a large amount of byproduct steams, and steam generating system can be oxidation coating, phthalic anhydride, maleic anhydride production device or boiler etc.Meanwhile, the steam generating systems such as oxidation coating need a large amount of thermals source in the time driving, and must have auxiliary electric heating or start up boilers.So oxidation coating, phthalic anhydride, maleic anhydride production device also can be used as steam and use system in the time driving, as can be seen here, the heat releases in process of production such as oxidation coating, phthalic anhydride, maleic anhydride production device, while going into operation, the device of heat absorption both can be used as steam generating system, can be used as again steam and used system.Plasticizer production device, acrylic acid production device etc. need thermal source, so plasticizer production device, acrylic acid production device etc. use system as steam.Along with the expansion of scope of the enterprise, steam generating system and steam use system very many.The present invention uses the steaming device of system to be connected by main steam header road all steam generating systems and steam, thermal source is flowed in steam generating system and steam use system, can realize the double fluid of steam to regulating and balance, the steam of the each covering device of balance adjustment, can also facilitate the driving of each device, reduce energy consumption and driving time, can also ensure safe, efficient, the long-term operation of steam pipe line.Steam generating system preferably arranges 1-10, and steam uses system preferably to arrange 1-10.
Each steam generating system and steam use system also to comprise the bypass of main steam header road, main steam header in parallel road bypass on each main steam header road, main steam header road bypass valve door is set in the bypass of main steam header road, main steam header road regulating valve is set on the main steam header road between bypass two ends, main steam header road, and main steam header road is positioned at pipe trench or push pipe.
The first filter is connected main steam header road with after the first drain valve series connection again with after the parallel connection of drain valve bypass valve;
Pressure gauge and thermometer are set on main steam header road.
When use, the main steam header road of each steam generating system is connected, and pressure gauge and thermometer are set on main steam header road.When grid-connected, because main steam header road is thicker than the bypass of main steam header road, prevent from directly opening main steam header road regulating valve, pipeline is impacted, first open each main steam header road bypass valve door, pipeline carried out to preheating, realize the vapor communication of valve both sides stable after, open again main steam header road regulating valve, more the life-span of safety and raising pipeline.The first filter and the first drain valve play hydrophobic effect, and drain valve bypass valve used as when maintenance.
As several steam generating systems are positioned at different positions, the laying in main steam header road can run into the many and various landform restriction of obstacle.How complying with different terrain, is the problem that needs solve by steam line safety, laying smoothly.
If while laying at green belt, spacious place, main steam header road can be positioned to pipe trench.In the time that main steam header road is positioned at pipe trench, pipe trench top arranges cover plate, and in pipe trench, bottom arranges the first support pier, is fixedly installed the first pipe support on the first support pier, places main steam header road on the first pipe support.Pipe trench is U-shaped pipe trench, pours into U-shaped pipe trench with reinforced concrete, and pipe trench top arranges cover plate, can open cover plate accessible pipe duct overhauls, in pipe trench, bottom arranges the first support pier, is fixedly installed the first pipe support on the first support pier, and main steam header road is placed on the first pipe support.
In the time that the steam generating system of different industrial parks is communicated with by main steam header road, if run into across situations such as highway, enterprise doorway, sewer line and elastic cable papers, main steam header road can be positioned to push pipe.In the time that main steam header road is positioned at push pipe, in push pipe, bottom is provided with the second support pier, is fixedly installed the second pipe support on the second support pier, places main steam header road on the second pipe support, and the second support pier inside is provided with drain opening.The degree of depth of push pipe, generally at underground lower 5-6 rice, is adjusted as required, darker sometimes.Drain opening has been eliminated the ponding that may exist between each basis.In push pipe inner side, pipeline support basis is set, is placed on pipeline support basis in the main steam header road of push pipe inner side, pipeline support basis is set, make main steam header road more firm.The second support pier and the preferred interval setting of pipeline support basis.
Bottom, main steam header road is provided with separatory bag.Bottom, main steam header road is provided with separatory bag, and separatory bag bottom connects sump or condensate return pipe line by pipeline, and this pipeline is provided with sewage draining valve; Separatory bag one side connects sump or condensate return pipe line by pipeline, and this pipeline is provided with the second filter and the second drain valve.
Work as driving, when parking, pipeline suddenly cold and hot, in pipeline, can produce water of condensation, large especially to the impact force at bend place especially, bottom, main steam header road is provided with separatory bag, the water of condensation producing enters in separatory bag, in the time that main steam header road is longer, generally that main steam header road is while being greater than 100 meters, two ends and centre in main steam header road all arrange separatory bag, open sewage draining valve, the water of condensation producing enters sump or condensate return pipe line through sewage draining valve, or close sewage draining valve, open the second filter, water of condensation filters dirt through the second filter, enter sump or condensate return pipe line through the second drain valve, filter dirt through the second filter, prevent from stopping up the second drain valve.
In sum, the present invention has the following advantages:
(1) the present invention connects the steam line that overlaps steam generating system more, realizes the double fluid of steam to regulating and balance, can ensure safe, efficient, the long-term operation of steam pipe line.
(2) the present invention proposes in long distance pipeline is laid, and adopts the modes such as pipe trench, push pipe to solve the extreme terrain running into.
(3) the present invention has solved the hydrophobic problem in push pipe internal steam pipe road simultaneously.
