Description
Technical field
The present invention relates to the tubular heater technical field in petroleum refining, petrochemical industry and other chemical industry, be specifically related to the heating furnace that a kind of coil pipe is drawable.
Background technology
(1) structure of traditional heating stove designs and function
Heating furnace is the tap in petrochemical industry, including atmospheric pressure kiln, vacuum furnace, SECTION TUBE FOR HYDROGEN MANNU-FACTURING FURNACE, reformer, coking furnace, reburner and pyrolysis furnace etc..The effect of tubular heater is that medium (oil plant or gas) is heated to the temperature needed for technique.
The four sides of body of heater is surrounded burner hearth by tall and big furnace wall, and furnace wall is by profile steel frame upper berth welding steel plates such as I-steel, and on steel plate, distribution welding bar for line, is molded into heat insulation and high-abrasive material between bar for line.The support installed on furnace wall supports tube sheet, boiler tube is supported through perforated pipe plate by tube sheet, flow through in boiler tube is the oil plant needing heating, and flow through from the bottom up in burner hearth outside boiler tube is high-temperature flue gas or hot blast, and heat passes to the oil plant in pipe or other medium by tube wall.
Such as, ethane cracking furnace is assembled up and down by convection section and the big section of radiant section two, and one the 150000 tons/year general overall dimensions of ethane cracking furnace convection section often reach long 18m × high 28m × wide 3m, belong to towering steel construction.
(2) current heating furnace method of construction
Due to historical reasons, during body of heater is built, traditional usual practice is that enginerring works produce the accessories such as tube sheet, finned tube and elbow, is then responsible for, at building-site, these parts are assembled into together with steel construction furnace wall body of heater by Construction Company overall.At device site welding technology, its boiler tube pierce into and anti-revisionist, the furnace wall surface of the assembly welding of elbow and the ray detection of weld seam, weld defect is strict sprays paint all because the construction of outdoor high-altitude brings inconvenience, having gap with the HSE policy of modern project management, furnace wall Wear-resistant heat insulation lining is affected meeting strain cracking by weather, get loose or drench with rain inefficacy.
The beginning of this century, Modular petrochemical-engineering heating furnace building technology is developed and applied, each heating furnace is by the module closed assembly or assembled of some cuboids, each module includes the journal stirrup inside both sides furnace wall, furnace wall, tube sheet, boiler tube, middle header and the header box at two ends, on two furnace walls of bottom, be provided with regulation and the fixed mechanism of both sides furnace wall spacing in each module, governor motion through the wall thickness of furnace wall, be mutually symmetrical with matching the furnace wall of both sides set of.Module top connects truss structure or the hanger having convenient lifting.The furnace wall top and bottom of each group of module all have substantial amounts of circular bolt holes.Change heating furnace to carry out, at device building-site, the modularity that the assembly welding of parts is on-the-spot and " play with building blocks " formula new construction method.Technology path is: (1), according to the overall dimension of heating furnace and transportation route, is designed as length and the most some of weight the segmentation of heating furnace entirety, so reaches the purpose broken the whole up into parts；(2) the complete each module of assembly welding body of heater in maker plant building；(3) modular transportation is installed to building-site.
(3) problem that modularized design building technology exists
Existing modular construction method is all first assembly welding each heat exchange coil module good, then multiple complete heat exchange coil modules are built, and convection section bottom coil pipe often selects the boiler tube of high-grade material because of radiation and higher temperatures flue gas environment, the delivery cycle of boiler tube is relatively long, the manufacture supply of material of delayed convection section lower module, need the requirement first installing lower module to contradict with device in-site installation, become the key of large project construction progress.
All there is a common old furnace wall and repair problem in the modularity building technology that either conventional construction techniques of heating furnace is still innovated.The lining of convection section is generally lightening casting material form, in pyrolysis furnace running, once furnace wall castable is aging or other reasons produces cracking, peels off, when needing to repair, it is necessary to blowing out immediately, then open header box, destroy weld seam between boiler tube and elbow, being extracted out by boiler tube, then repair lining or adjust boiler tube, the elbow dismantled can not repeat use.During this, whole cracking furnace installation must quit work, then dismount and repair, and workload is the hugest, and work difficulty is higher.Because space is the narrowest in furnace wall, it is again the most poor at device site operation, construction environment and construction equipment, cannot ensure to repair the quality of lining, it cannot be guaranteed that pyrolysis furnace has the higher thermal efficiency and longer service life, make convection section maintenance cost higher, there is potential safety hazard.
As can be seen here, petrochemical heating furnace is designed and improvement in terms of building technology, can increase economic efficiency, there is the strongest engineering significance.
