Abstract
The utility model relates to a dual bow shape facing bar oil slurry steamer and belongs to a steamer comprising a heat exchange tube bundle inside the casing. The heat exchange tube bundle is supported by the dual bow shape facing bar, each pipe end of the heat exchange tube bundle is connected with the macro groove weld point and the wide expansible band slot, a wave gear composite gasket is added into the encapsulation point of the floating tube sheet and the floating epicranium. Wherein, the dual bow shape facing bar comprises a bow-shaped plate and a rectangular plate which are in parallel; the bow-shaped plate and the rectangular plate are axially arranged in a certain distance alternatively along the heat exchange tube bundle, two sides of the transverse cross-section are the bow-shaped plates, and the middle of the transverse cross-section is the rectangular plate. The utility model has reasonable design, simple structure, no leakage, and long service life, which increases economic benefit.
Description
Technical field
The utility model belongs to steam raising plant, particularly relates to a kind of bouble-bow shape support plate oil slurry steam generator.
Background technology
The circulation oil slurry steam generator belongs to the large-scale middle thick tube sheet movable tube sheets heat exchanger of three classes of pressing, and is the energy-conservation key equipment of heavy-oil catalytic device.After the mid-90, following problem has appearred in this equipment in running in eighties of last century: the welding point that heat exchanger tube connects with tube sheet cracks and pipe bridge is torn; Vessel flange connects sealing place and leaks.Because the problems referred to above directly produce following harm consequence: because the crackle that tube sheet produces makes the shell side WATER AS FLOW MEDIUM enter in the tube side medium slurry oil, the water that enters slurry oil is converted into steam, reduced the energy-saving and cost-reducing economic benefit of device, even shut-down (breakdown) mainteance, safety in production has brought hidden danger to device.
Summary of the invention
The present invention is intended to overcome the deficiencies in the prior art, on the basis that does not change the oil slurry steam generator procapsid, structure and tube bank critical process manufacturing process by the tube bank of design New Cycle oil slurry steam generator, a kind of bouble-bow shape support plate oil slurry steam generator is provided, solve leakage problem, thereby guaranteed the long-term operation of device.
Bouble-bow shape support plate oil slurry steam generator of the present utility model is that the heat-exchanging tube bundle formation has been installed in housing, it is characterized in that heat-exchanging tube bundle is by bouble-bow shape support plate support fixation, each pipe end and the tube sheet of heat-exchanging tube bundle is to be fixed by big groove solder joint and wide expansible band groove to connect, and sealing place of floating tubesheet and floating head adds incoming wave tooth composite gland bush.
As further improvement of the utility model, bouble-bow shape support plate is to be made of two cambered plates arranged side by side and a rectangular slab; Be that cambered plate and rectangular slab are alternately arranged at regular intervals vertically in the heat-exchanging tube bundle, the both sides of laterally arranging on the section are that cambered plate, centre are rectangular slab.
The heat exchanger tube of heat-exchanging tube bundle of the present utility model is Large ratio surface convergent-divergent pipe, spiral grooved tube, broken line shape convergent-divergent pipe, bellows tube, trapezoidal finned tube etc., adopt above-mentioned efficient heat-exchanging pipe, adjust by conducting heat, do not reduce under the situation of original heat exchange amount in assurance, reduce heat exchanger tube quantity, increase pipe bridge thickness, thereby increase tube pitch, reduce the flow resistance of bubble and liquid, reduce tube vibration.
Bouble-bow shape support plate oil slurry steam generator of the present utility model is reasonable in design, simple in structure, nothing is revealed, the life-span is long, improved the economic benefit of installing.

Embodiment
Bouble-bow shape support plate oil slurry steam generator of the present utility model is heat-exchanging tube bundle 2 to be installed constitute in housing 1, the heat exchanger tube of heat-exchanging tube bundle 2 can be Large ratio surface convergent-divergent pipe, helix tube, trapezoidal finned tube, bellows tube etc., because pipe bridge thickens, and has reduced peak stress, avoid the pipe bridge cracking.Heat-exchanging tube bundle 2 is by bouble-bow shape support plate 3 support fixation, and bouble-bow shape support plate 3 is to be made of two cambered plates arranged side by side 10 and a rectangular slab 11, the part in no area under control excision on the bouble-bow shape support plate.Strengthen the constraint of exchange heat pipe like this, reduced the oscillation phenomenon of heat exchanger tube, reduced the vertically mobile resistance of bubble and liquid simultaneously and enlarged the interior evaporating space of shell side again, further reduced bundle vibration.In the heat-exchanging tube bundle 2 vertically two of poling cambered plates 10 arranged side by side be alternately to arrange at interval with rectangular slab 11, the both sides of laterally arranging on the section be cambered plate 10, middle be rectangular slab 11.Each pipe end of heat-exchanging tube bundle 2 and tube sheet 4 are to be fixedly connected by big groove solder joint 5 and wide expansible band groove 6, this type of attachment in contrast to conventional intensity weldering+subsides and expands, no matter be because thermal (temperature difference) stress or vibration cause the axial float of pipe, all play thrust function, reduced the shear stress of weld bond, also can avoid the big and crevice corrosion effect that produces in heat exchanger tube and tube sheet gap in addition, the width and the bevel for welding size that increase the expansible band groove can increase heat exchanger tube and tube sheet linking intensity, have further improved the performance of weld bond antifatigue.Floating tubesheet 7 adds incoming wave tooth composite gland bush 9 with sealing place of floating head 8.This seal form not only can have been avoided leaking but also can to overcome the difficulty of processing of in the past taking the steel ring rim strip big, the shortcoming that rehabilitation cost is high.
