Description
Technical field
The utility model relates to LARGE DIAMETER FRP cylinder or chimney technical field, belongs to a kind of mould of production LARGE DIAMETER FRP cylinder.
Background technology
The enforcement of the U.S. and western countries' environmental protection policy particularly to the flue gas desulfurization of smoke stack emission, is promptly adopted desulphurization plant and technology to remove sulfur in smoke and is started from the eighties of last century end of the seventies and the beginning of the eighties.China uses and technological transformation since 2005 technology of carrying out chimney in service and newly-built chimney are carried out desulfurization in China, to reduce the discharge capacity of Chinese sulfur dioxide under the encouragement of national environmental protection policy and requiring.
What most desulfurization was adopted is wet desulphurization, after both flue gas has come out from boiler, through desulfurizing tower and inner alkaline aqueous solution spray, enters flue and chimney again and carries out airborne release.But, still have about 5% sulfur dioxide to be included in the middle of the discharged flue gas.Because the temperature of flue gas is about 50 degrees centigrade, mix to have formed dilute sulfuric acid with the oxygen G﹠W.Dilute sulfuric acid causes sour corrosion to concrete and steel flue gas duct and chimney.Corrosion can cause concrete and steel stack local damage and large tracts of land damage to occur for a long time, even caves in.
High temperature dry flue gas (130-150 degree centigrade) in the chimney during the not desulfurization of industrial and mineral of flue gas, the ultra-high temperature flue gas (180 degrees centigrade) of the short time when low temperature wet flue gas (about 50 degrees centigrade) during the desulfurizing tower operation and generating set starting up.
In the large-scale popularization desulfur technology; very serious problem is but appearring aspect the structural defence of chimney: be exactly no matter adopt any external; domestic anti-corrosion material; even almost the chimney more than 90% has used anti-corrosion material or technology; in addition less than the time in 1 year in all produce to leak; the result is penetrated on the concrete and steel of matrix, the structure of grievous injury chimney and safety.Only can reach more than hundreds of hundred million RMB in the economic loss that causes in China.
The chimney corrosion-proof lining of present desulfurization (FGD) divides several big classes basically: the coating class, the clay class is built glass block and foamed bricks by laying bricks or stones, paster class, alloy-steel plate and titanium plate class, and fiberglass.
The coating class is easy to crack, comes off, and thickness is limited; Clay class impermeabilisation type is poor, and the cracking that comes off is more.Glass block and foamed bricks engineering time are long, and several ten thousand seams are in case several damages cause integral body to build the damage in slit by laying bricks or stones easily, and damage has related property; Also because bonding slit is too many, damage also has related property to the paster class; Titanium alloy sheet costs an arm and a leg, and weld seam and plate face all are prone to damage, leaks more, also inevitable; The fiberglass chimney is good because of the temperature resistance anti-corrosive properties at present, and dependable performance is applied in gradually and increases.
The main cause of the failure of above chimney anticorrosion material is because anti-corrosion material contacts with the direct of acidproof brick liner with concrete, and when causing corrosion-proof lining to damage, acid accumulator penetration causes structural failure on acidproof brick and concrete chimney housing.
Damage for fear of chimney structure, the chimney internal cylinder in chimney housing or supporting construction arises at the historic moment, and inner core is divided into steel inner cylinder, acidproof brick/concrete inner core and fiberglass inner core.Because steel and concrete inner core be sensitive for damages still, fiberglass inner core operational effect is better at present.
But, in the process of using fiberglass (also claiming FRP or composite) inner core, the fiberglass inner core of big caliber, diameter is greater than 3.5 meters or 4 meters the time, must near chimney, build interim vertical wrapping machine and carry out the manufacturing of fiberglass inner core, to avoid being transported to the high expense at chimney scene by factory process, maybe can not transportation property.
Even but big caliber inner core carries out the vertical winding production of glass reinforced plastic pipe at the scene, in the time of at diameter to 3.5 meter or more than 4 meters, even the 5-10 rice diameter, on-the-spot twine to produce also great difficulty can appear, influenced by weather, temperature, wind-force etc.; During installation, also need the perforate of existing chimney flue large tracts of land is transported the glass reinforced plastic pipe of integral body in the chimney.Simultaneously, glass reinforced plastic pipe in the chimney is lifted, also very high to the requirement of crane gear.
Above problem has still limited the extensive use of big caliber fiberglass inner core greatly.Major limitation is the processed complex of big caliber fiberglass inner core, the transportation difficulty, and the construction complexity, thus cause cost to strengthen, be difficult to be accepted by the industrial user.
