Description
Technical field
The present invention relates to the heat-exchange apparatus technology, particularly relate to a kind of combinable circular tubular heater.Can be applicable to the heat-exchange apparatus of equipment industries such as petroleum refining and chemical industry, Coal Chemical Industry, chemical fertilizer, air-conditioning, air cooling, boiler, electric power facility, be particularly suitable for the flue gas heat-exchange apparatus of various chemical industry and chemical fertilizer industry stove through medium heating or cooling.
Background technology
Industrial furnace is the key equipment in the production process common in the petrochemical plant.For example, oil refining and petrochemical plant tubular heater, reburner, pyrolysis furnace; Being the gasification furnace of raw material with the coal or being the one-stage converter, secondary reformer etc. of raw material with the combustion gas of synthetic ammonia installation heat, pyroreaction.The type of the industrial furnace in the petroleum chemical industry is more, and tubular heater is one of type of furnace the most frequently used in the petroleum chemical industry.
In the prior art, tubular heater belongs to a kind of flame heat equipment that thermal source is provided, and its effect is the medium in the boiler tube to be heated to temperature required, gets into next segment process process then.In tubular heater; Fluid media (medium) in the heat transferred boiler tube that fuel combustion discharges; This boiler tube is positioned among the combustion chamber with refractory material encirclement, and the type of tubular heater is usually according to its structure and shape, and the form of radiating furnace tube and the layout of burner are divided.Contained according to the petroleum chemical industry standard SH/T of the People's Republic of China (PRC) 3036-2003 " general oil refining apparatus is used flame heating furnace ", by the structure and shape classification, cylindrical furnace, batch-type furnace, vertical heater and multicell box-type furnace etc. are arranged.By the radiating furnace tube formal classification: vertical pipe type, horizontal tube, helix tube type and U-shaped tubular type etc. are arranged.Arrangement classification according to burner has end burning, tipburn and side to burn.The structure and shape of heating furnace can make up between the form of radiating furnace tube and the layout three of burner each other, is illustrated in figure 1 as " U " shape box type stove 10, wherein, has furnace shell 11 and " U " shape boiler tube 12; Be illustrated in figure 2 as helix tube cylindrical furnace 20, wherein, have furnace shell 21 and coil pipe 22.
The tubular heater of prior art is made up of radiation chamber, convection cell and chimney usually, and boiler tube all is housed in radiation chamber and the convection cell, and baffle plate is housed in the chimney.Fuel burns at radiation chamber through nozzle; The thermal-flame that produces is with the radiant heat transfer mode; Most of heat is passed to the medium that is flowing in the radiation chamber boiler tube, and the high-temperature flue gas after temperature reduces gets into convection cell again, continues that with convection type the part heat is passed to the medium that is flowing in the convection cell boiler tube and carries out preheating; Flue gas after the cooling finally gets into flue, enters atmosphere through chimney.The flow direction of medium generally is the boiler tube of elder generation through convection cell, passes through the boiler tube of radiation chamber again.Its medium constantly absorbs the heat that high-temperature flue gas transmits through furnace wall in flow process, progressively being elevated to needed temperature becomes the high-temperature medium outflow.And in order to fully utilize the energy, part is set up residual neat recovering system between convection cell and flue and body of heater usually, adds hot-air, or adds hot water, water vapour and generate steam or superheated steam, uses for producing.
The body of heater of this tubular heater of the prior art generally comprises the boiler tube of furnace shell, furnace shell inside and is arranged at the burner of furnace shell, and its contour structures is integrated.The method of construction of the tubular heater of this integral structure is normally produced accessories such as tube sheet, suspender member, boiler tube and elbow by enginerring works, be responsible at building-site these parts being assembled with the furnace wall of steel construction and be built into body of heater integral body by construction company is installed then.
Yet; The method of construction of the tubular heater of above-mentioned traditional integral structure needs a large amount of at the scene assembly weldings constructions; And the piercing into of its boiler tube, all need on-the-spot open-air high-altitude construction with technology such as spraying paint of anti-revisionist, the surperficial strictness of furnace wall of the ray detection of the assembly welding of elbow and weld seam, weld defect; This open-air high-altitude construction is given to install to build and is brought inconvenience, and there is bigger gap in the HSE policy that this and modern project are managed.And the wear-resisting insulated lining of furnace wall is subject to the influence of weather, strain cracking, gets loose, and inefficacy perhaps drenches with rain.Therefore, the inconvenience of this open-air high-altitude construction and various inspections is prone to cause the duration to receive boisterous the influence, and its build guality also is difficult to guarantee that also there is hidden danger in production safety.
Along with The development in society and economy, the production scale of various chemical plant installations continues to increase, and the volume of tubular heater is also more and more huger; Design and construction for tubular heater with inflammable and explosive medium; The wind resistance of its tall and slender structure shakes also increasingly high with the requirement of the intensity of seismic (seismal effect, and, a lot of chemical plant installations all addressing in the bigger coastal area of typhoon; Make cost of investment rise significantly, this has become a noticeable techno-economic question.
In sum; The quality of each operation can be enough monitored in user and engineering management for ease; Reach the demand of reduction of erection time, and be directed against the deficiency of prior art, needing badly provides a kind of modularization of can carrying out to build; Avoid at the building-site assembly welding, and assembling is simple, construction cost is lower, the duration is short, the combinable easily circular tubular heater of maintenance.
