Description
Technical field
The utility model belongs to a kind of steam generator device for oil, chemical industry, coal chemical technology, relates to the reformed gas steam generator of petrochemical industry device for producing hydrogen in particular.
Background technology
Along with rapid economic development, develop especially fast as the most important petrochemical industry of the energy, reformed gas steam generator plays a part very important in the equipment of device for producing hydrogen.
Reformed gas steam generator, also known as waste heat boiler or waste heat boiler, its objective is and utilizes high temperature logistics in production process as thermal source producing steam in next life, domesticly uses polytype reformed gas steam generator at present, and wherein fixed tube sheet type adopts more.According to the use experience of device, a kind of tube sheet adopts flexible tube sheet, high temperature tube sheet and heat exchanger tube to adopt inner bore welding technique, heat exchanger tube to adopt the comparatively bassoon of one group, center, around the reformed gas steam generator result of use of Minute Tubule Structures and employing thermoregulative mechanism is better, improves device security further.
Because the structure of reformed gas steam generator limits, heat-exchanging tube bundle cannot be changed separately, and the security performance of the welding point of exchanger tubes and tubesheets is particularly important, directly has influence on the service life of whole equipment.In shell side, medium is mainly the sparging process of water generates steam, and the vibration effect of heat exchanger tube is to the quality of weld joint of exchanger tubes and tubesheets.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of shockproof reformed gas steam generator, better can prevent heat exchanger tube from producing vibration while making full use of shell side circulation area.
For achieving the above object, the one that the utility model provides shockproof reformed gas steam generator is made up of bobbin carriage, housing, little heat exchanger tube, the large heat exchanger tube in center, vibration abatement, support plate, tube sheet, control valve, outer skull, described housing realizes being connected by welding with two ends tube sheet, composition shell side cavity, case top and bottom are respectively arranged with steam (vapor) outlet and water inlet.Be provided with little heat exchanger tube, the large heat exchanger tube in center, vibration abatement, support plate in housing, little heat exchanger tube and the large heat exchanger tube in center and two ends tube sheet realize being connected by welding, and add bobbin carriage, outer skull forms a tube side cavity.
Described vibration abatement is arranged in the position of enclosure interior near two ends tube sheet, vibration abatement is combined by two pieces of bump protection ring fore-and-aft clearances and installs, spacing between bump protection ring controls at 150mm ~ 450mm, bump protection ring is by supporting that circle and shockproof bar are formed, shockproof bar is fixed by welding in be supported on circle, and little heat exchanger tube effectively limits the scope of activities of little heat exchanger tube through the surrounding being arranged in little heat exchanger tube due to shockproof bar after vibration abatement.
The advantage of a kind of shockproof reformed gas steam generator of the utility model is: because little heat exchanger tube rigidity under certain span of arranging in tube sheet outer ring is poor; produce vibration; in the surrounding of little heat exchanger tube, little heat exchanger tube is protected by the rod baffle interlaced arrangement of vibration abatement, prevent vibration.The layout of rod baffle can change with the difference of the arrangement mode of heat exchanger tube.
Vibration abatement manufacturing structure is simple, economical and practical, does not affect the heat transfer area of shell side medium simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model, and wherein part A is vibration abatement assembling design sketch.
Fig. 2 Fig. 3 is vibration abatement structural representation.
Fig. 4 is the design sketch after vibration abatement and little heat exchanger tube assemble.
Comprising: bobbin carriage 1, housing 2, little heat exchanger tube 3, the large heat exchanger tube in center 4, vibration abatement 5, support plate 6, tube sheet 7, control valve 8, outer skull 9, support circle 10, shockproof bar 11.
Detailed description of the invention
Below in conjunction with accompanying drawing 1 Fig. 2 Fig. 3 Fig. 4, embodiment of the present utility model is described; the principle that the present embodiment is just described described in the present embodiment and description; the utility model is not limited to embodiment; be combined the expansion in field; the utility model will have and improve or change, these changes and to change will be all in claimed scope.
A kind of shockproof reformed gas steam generator, be made up of bobbin carriage 1, housing 2, little heat exchanger tube 3, the large heat exchanger tube in center 4, vibration abatement 5, support plate 6, tube sheet 7, control valve 8, outer skull 9, described housing 2 realizes being connected by welding with two ends tube sheet 7, composition shell side cavity, case top and bottom are respectively arranged with steam (vapor) outlet and water inlet.Be provided with little heat exchanger tube 3, the large heat exchanger tube 4 in center, vibration abatement 5, support plate 6 in housing 2, little heat exchanger tube 3 and the large heat exchanger tube 4 in center and two ends tube sheet realize being connected by welding, and add bobbin carriage 1, outer skull 8 forms a tube side cavity.Described vibration abatement 5 is arranged in the inner position near two ends tube sheet 7 of housing 2, vibration abatement 5 is installed by combination before and after two pieces of bump protection rings, spacing between bump protection ring controls at 150mm ~ 450mm, bump protection ring is by supporting that circle 10 and shockproof bar 11 are formed, shockproof bar 11 is fixed by welding in be supported on circle 10, little heat exchanger tube 3 effectively limits the scope of activities of little heat exchanger tube through the surrounding being arranged in little heat exchanger tube 3 due to shockproof bar 11 after vibration abatement 5, prevent little heat exchanger tube 3 to vibrate, improve the welding point service life of little heat exchanger tube 3 and tube sheet 7.
