Abstract
The utility model relates to the field of circulation fluidized bed boiler equipment, in particular to an expansion joint tool special for a boiler slagging pipe. The expansion joint tool special for the circulation fluidized bed boiler slagging pipe comprises a slag inlet pipe (1), a slag discharging pipe (6), a middle bellows (2), a movable sealed inner barrel (3), an aluminium silicate fibre felt (4) and slag stabbed holes (5). The middle bellows (2) is arranged between the slag inlet pipe (1) and the slag discharging pipe (6). The inner side of the middle bellows (2) is provided with the aluminium silicate fibre felt (4), and the inner side of the aluminium silicate fibre felt (4) is provided with the movable sealed inner barrel (3). The slag stabbed holes (5) are arranged at one side of the slag discharging pipe (6), and outlets of the slag stabbed holes (5) incline towards a side lower portion. The expansion joint tool special for the circulation fluidized bed boiler slagging pipe eliminates influences of dislocation, stress concentration, and cracking of the slag inlet pipe caused by thermal expansion, ubiquitous problems that slag can be gushed out from a slag tap in the process of slagging are resolved, and phenomenon that safety of unit and personnel is seriously threatened no longer exists. Service life of the boiler equipment is prolonged, and the expansion joint tool special for the circulation fluidized bed boiler slagging pipe can be adapted to a variety of environments to operate.
Description
Technical field:
The utility model relates to the Circulating Fluidized Bed Boiler Equipment field, what be specifically related to is the special-purpose expansion joint of a kind of boiler slag-discharge pipe.
Background technology:
Slag-discharge pipe sprays the problem of slag during at present CFBB ubiquity slagging, has the accident potential of serious threat unit and personal safety.
During boiler work operation, when boiler bottom slag-discharge pipe and the thermal expansion of cylinder cooler feed end, can produce vertical displacement and horizontal displacement, the generation stress that is rigidly connected is concentrated, usually so that the slag-discharge pipe cracking causes the phenomenon that occurs spraying slag, leaks ash.And during blanking, can produce reentrainment of dust, splash, meeting is shortened the service life of bellows so that dust falls in the bellows.
The utility model content:
The purpose of this utility model provides the special-purpose expansion joint of a kind of slag discharge pipe of circulating fluidized bed boiler, it can be eliminated, and the slag-discharge pipe dislocation stress that thermal expansion causes is concentrated, the impact of cracking, the problem of slag-discharge pipe spray slag when having solved the ubiquity slagging, do not exist serious threat unit and personal safety, improved the running time of boiler plant, can adapt under the multiple environment and work.In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises slag feed pipe 1, residue outlet 6, middle bellows 2, movable sealing inner core 3, alumina silicate fiber felt 4, discloses cinder hole 5, middle bellows 2 arranges between slag feed pipe 1 and the residue outlet 6, the inboard of middle bellows 2 is provided with alumina silicate fiber felt 4, alumina silicate fiber felt 4 inboards are provided with movable sealing inner core 3, disclose cinder hole 5 and be arranged on a side of residue outlet 6, and disclose the oblique side-lower of outlet of cinder hole 5.
Described movable sealing inner core 3 is comprised of upper movable inner core 3-1, lower movable inner core 3-2, upper movable inner core 3-1 is arranged on lower movable inner core 3-2 top, and the end portion of upper movable inner core 3-1 is arranged on the outside of lower movable inner core 3-2 upper part, and upper movable inner core 3-1 and lower movable inner core 3-2's overlaps.
Eliminated in the utility model that the slag-discharge pipe dislocation stress that thermal expansion causes is concentrated, the impact of cracking, the problem of slag-discharge pipe spray slag when having solved the ubiquity slagging, do not exist serious threat unit and personal safety, improved the running time of boiler plant, can adapt under the multiple environment and work, take full advantage of simultaneously surrounding space, be convenient to disclose slag.During boiler work operation, when boiler bottom slag-discharge pipe and the thermal expansion of cylinder cooler feed end, vertical displacement and horizontal displacement have been produced, bellows 2 absorbs in the middle of the utility model design, having eliminated the stress that produces that is rigidly connected in the past concentrates, do not have the hidden danger of slag-discharge pipe cracking, whole device is an airtight space, also just can not occur spraying slag, leak grey phenomenon.Also can not produce reentrainment of dust when blanking, splash, design activity sealing inner core stops dust to drop into the bellows the inside, and fill alumina silicate fiber felt 4 between this, reduces the operating temperature of bellows, has prolonged the service life of whole device.Boiler work running occurs once in a while that fluidisation is bad, during knot bulk slag, gathers easily obstruction, considers that furnace bottom is restricted in the space up and down, discloses cinder hole 5 in the side design one of residue outlet 6, convenient on-the-spot block clearing, conserve space and time.In sum, the utility model has guaranteed that boiler operatiopn stablizes superior more under the working environment of height running, high efficiency, high request.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
Referring to Fig. 1, this specific embodiment is by the following technical solutions: it comprises slag feed pipe 1, residue outlet 6, middle bellows 2, movable sealing inner core 3, alumina silicate fiber felt 4, discloses cinder hole 5, middle bellows 2 arranges between slag feed pipe 1 and the residue outlet 6, the inboard of middle bellows 2 is provided with alumina silicate fiber felt 4, alumina silicate fiber felt 4 inboards are provided with movable sealing inner core 3, disclose cinder hole 5 and be arranged on a side of residue outlet 6, and disclose the oblique side-lower of outlet of cinder hole 5.
Described movable sealing inner core 3 is comprised of upper movable inner core 3-1, lower movable inner core 3-2, upper movable inner core 3-1 is arranged on lower movable inner core 3-2 top, and the end portion of upper movable inner core 3-1 is arranged on the outside of lower movable inner core 3-2 upper part, and upper movable inner core 3-1 and lower movable inner core 3-2's overlaps.
Eliminated in this specific embodiment that the slag-discharge pipe dislocation stress that thermal expansion causes is concentrated, the impact of cracking, the problem of slag-discharge pipe spray slag when having solved the ubiquity slagging, do not exist serious threat unit and personal safety, improved the running time of boiler plant, can adapt under the multiple environment and work, take full advantage of simultaneously surrounding space, be convenient to disclose slag.During boiler work operation, when boiler bottom slag-discharge pipe and the thermal expansion of cylinder cooler feed end, vertical displacement and horizontal displacement have been produced, bellows 2 absorbs in the middle of the design of this specific embodiment, having eliminated the stress that produces that is rigidly connected in the past concentrates, do not have the hidden danger of slag-discharge pipe cracking, whole device is an airtight space, also just can not occur spraying slag, leak grey phenomenon.Also can not produce reentrainment of dust when blanking, splash, design activity sealing inner core stops dust to drop into the bellows the inside, and fill alumina silicate fiber felt 4 between this, reduces the operating temperature of bellows, has prolonged the service life of whole device.Boiler work running occurs once in a while that fluidisation is bad, during knot bulk slag, gathers easily obstruction, considers that furnace bottom is restricted in the space up and down, discloses cinder hole 5 in the side design one of residue outlet 6, convenient on-the-spot block clearing, conserve space and time.
