Abstract
The invention is a slurry oil steam generator manufacturing method, used in a remaining heat of catalytic cracking equipment recovering and heat exchanging system of petrochemical industry. It enlarges evaporation space between shell side and heat exchange pipe as well as between shell and heat exchange pipe; both the shell side and the shell are arranged axially and uniformly with a group of ascending pipes and descending pipes; the distance between the heat exchange pipes on a pipe plate and a support plate is greater than that of an ordinary heat exchanger and the pipe beam axially adopts the support plate to make the heat exchange pipes obtain an excellent support. The no-heat exchange pipe parts on the top and bottom sides of the support plate are cut off and the left and right sides of the support plate are uniformly made with holes, the connector adopted between the pipe plate and the heat exchange pipe is a butt connector; flexible graphite and enhancement metal combined pad sealing structure and other structures are adopted between internal floating head and floating pipe plate, which increases the service life of workpieces from less than half year to two or three years.
Description
Technical field
The present invention relates to the construction design method and the corresponding manufacturing processing method of oil slurry steam generator in the petroleum chemical industry catalytic cracking unit residual neat recovering system.
Background technology
Oil slurry steam generator is the key equipment in the petroleum chemical industry catalytic cracking unit residual neat recovering system.The safe operation of this equipment, the balance to the power consumption of polymer processing of whole device and full factory's different pressures grade steam production and consumption plays crucial effects.At present, domestic oil plant oil slurry steam generator just in use all adopts the floating head heat exchanger of common form, and following problem takes place in this equipment use:
1. the tube sheet of oil slurry steam generator runs through the shape crackle.Come into operation to from equipment and to run through the cycle that the shape crackle produces, short then about one month, long then half a year.
2. internal floating head sealing leak.
The consequence that the problems referred to above produced is as follows:
1. because steam pressure is higher than the heat exchanger tube internal pressure, and the steam of leakage is brought in the fractionating column with slurry oil, and fractionating column pressure is risen sharply, operation brings potential safety hazard to fractionating system.
2. be forced to reduce the pressure rating that steam takes place, lost the energy that reclaims on the one hand, increased the device power consumption of polymer processing, also can influence the balance of full factory different pressures grade steam production and consumption simultaneously.
3. if no stand-by equipment then must cut off the full device charging, resume production again behind the shut-down rush repair; Even stand-by equipment is arranged, urgent handover operation also will influence ordinary production.In any case, all will bring very big influence to the continuous production of whole device.
Summary of the invention
The present invention in the service life of improving this equipment, makes it reach the purpose of long period safe operation by the primary structure method for designing of change oil slurry steam generator and the machining manufacture of key components and parts.
Technical scheme of the present invention is as follows:
A kind of manufacture method of oil slurry steam generator, in pore arrangement and version, tube sheet and the floating tubesheet of support plate and the design of Sealing Structure method of heat exchanger tube jointing construction design method, floating tubesheet and internal floating head lid of selection, tedge and the down-comer of shell side diameter of the housing arrangement, fixed tube sheet and floating tubesheet and support plate on housing, it is characterized in that: the evaporating space between shell side housing 1 and the heat exchanger tube 7 strengthens the rational evaporating space of formation; The flow regime of shell side housing shaft when each has arranged that evenly one group of vapor uptake 2 has improved the steam access device with down-comer 3; Heat exchanger tube pitch of holes on tube sheet 4 and floating tubesheet 5 and the support plate 6 strengthens than common heat exchanger, adopt support plate to make heat exchanger tube obtain excellent support and support plate is reached both sides up and down not have excision of heat exchanger tube position and the even perforate in the left and right sides (Fig. 5) vertically heat exchanger tube, reduced the flow resistance that between pipe, produces in the steam steam bubble uphill process; Tube sheet and floating tubesheet and heat exchanger tube jointing adopt butt welded joint to improve joint bonding strength (Fig. 2); Adopt the compound seal with flat gasket structure 9 of soft graphite and reinforcement metal to improve sealing (Fig. 4) between internal floating head 8 and the floating tubesheet; Adopt the support plate of thickening, and the hardness of control support plate material therefor alleviates heat exchanger tube vibrations wearing and tearing a little less than the hardness of heat exchange tube material.

The specific embodiment
By the primary structure method for designing of change oil slurry steam generator and the machining manufacture of key components and parts, the service life of improving this equipment.Space strengthening in the selection of shell side diameter of the housing between shell side housing 1 and the heat exchanger tube 7 constitutes rational evaporating space; The flow regime of shell side housing shaft when each has arranged that evenly one group of vapor uptake 2 has improved the steam access device with down-comer 3; Heat exchanger tube spacing on tube sheet 4 and floating tubesheet 5 and the support plate 6 is enlarged to the heat exchange caliber more than 1.5 times, and heat exchanger tube adopts support plate to make heat exchanger tube obtain excellent support vertically, support plate is reached both sides does not up and down have excision of heat exchanger tube position and the even perforate in the left and right sides (Fig. 5), has reduced the flow resistance that produces between pipe in the steam steam bubble uphill process; Tube sheet and floating tubesheet and heat exchanger tube jointing adopt butt welded joint to improve joint bonding strength (Fig. 2); Adopt the compound seal with flat gasket structure 9 of soft graphite and reinforcement metal to improve sealing (Fig. 4) between internal floating head 8 and the floating tubesheet; Adopt the support plate of thickening, and the hardness of control support plate material therefor alleviates heat exchanger tube vibrations wearing and tearing a little less than the hardness of heat exchange tube material.
Oil slurry steam generator according to the present invention's trial-production was tried out nearly 1 year in certain factory.Equipment operation at present is normal, gives the meter life-span can reach two to three years.Factory was extended to two to three years with the overhaul life by 1 year create essential condition, economic benefit is very high.
