Abstract
The utility model provides a supporting structure for preventing a circulating fluidized bed boiler center cylinder from falling off, which has the advantages that a center cylinder can be firmly installed in a cyclone separator and cannot fall off, and the long-term running of the boiler is ensured. The technical scheme is that the supporting structure for preventing the circulating fluidized bed boiler center cylinder from falling off comprises a center cylinder and a separator top plate. The supporting structure for preventing the circulating fluidized bed boiler center cylinder from falling off is characterized in that fireproof material layers are arranged above and below the separator top plate; the upper part of the center cylinder penetrates into the fireproof material layers; an expansion clearance is reserved between the outer wall of the upper part of the center cylinder and the fireproof material layers; supports are uniformly distributed on the outer wall of the circumferential surface of the upper part of the center cylinder; bottom horizontal plates of the supports are supported to the upper end surface of the separator top plate, and are provided with long slotted holes which are configured along the expansion direction of the outer wall of the center cylinder; the supports are positioned in corresponding installation cavity bodies of the fireproof material layers.
Description
Technical field
The utility model relates to the technical field of boiler structure, is specially a kind of supporting structure for preventing that central cylinder of circulating fluid-bed boiler from coming off.
Background technology
Circulating fluidized-bed boiler Combustion technology is a coal combustion technology growing up over nearly 20 years.It has that fuel tolerance is wide, efficiency of combustion is high, discharged nitrous oxides is low, load regulation rate is large and the outstanding advantages such as Load Regulation is fast.Cyclone separator is the vitals of CFBB, Main Function is that the most flying dusts in flue gas are separated by material-returning device and return to burner hearth circulating combustion, wherein the central tube of cyclone separator has played very important effect, is the core of cyclone separator.But the running temperature of central tube is very high, conventionally between 900-1000 ℃, traditional fixed form comprises with pull bar fixes or hangs with boatswain chair, because temperature is high, central tube is exposed to again in flue gas, traditional is often hung mode or causes blowing out because thermal expansion inequality causes pull bar to break to cause central tube to come off, or boatswain chair due to for a long time under the condition of high temperature intensity decline and causing fracture to cause central tube to come off to cause blowing out, have a strong impact on the long-term stability operation of boiler.
Summary of the invention
For the problems referred to above, the utility model provides a kind of supporting structure for preventing that central cylinder of circulating fluid-bed boiler from coming off, and it makes central tube can be installed on securely cyclone separator inside, can not come off, and guarantees the long-term stability operation of boiler.
A kind of supporting structure for preventing that central cylinder of circulating fluid-bed boiler from coming off, its technical scheme is such: it comprises central tube, separator top board, it is characterized in that: the top of described separator top board, below is provided with refractory masses, described refractory masses is goed deep on the top of described central tube, the external wall of upper portion of described central tube and described refractory material interlayer leave expansion clearance, the top periphery outer wall of described central tube is evenly equipped with support, the bottom horizontal plate of described support is supported on the upper surface of described separator top board, on the bottom horizontal plate of described support, have long slot bore, described long slot bore is arranged along the expansion direction of central tube outer wall, described support is positioned at the correspondence of described refractory masses cavity is installed, the limited block arranging on described separator top board is positioned at described long slot bore, the top circumference face outer wall of described central tube is provided with sealing plate, it is inner that described refractory masses is goed deep in the outside of described sealing plate.
Adopt after structure of the present utility model, top due to separator top board, below is provided with refractory masses, described refractory masses is goed deep on the top of described central tube, the external wall of upper portion of described central tube and described refractory material interlayer leave expansion clearance, the top periphery outer wall of described central tube is evenly equipped with support, the bottom horizontal plate of described support is supported on the upper surface of described separator top board, on the bottom horizontal plate of described support, have long slot bore, described long slot bore is arranged along the expansion direction of central tube outer wall, the limited block arranging on described separator top board is positioned at described long slot bore, its expansion that guarantees central tube is even, and because the top circumference face outer wall of central tube is provided with sealing plate, it is inner that described refractory masses is goed deep in the outside of described sealing plate, it can prevent flue gas short circuit, the correspondence that is positioned at refractory masses due to support is installed cavity, support can be not for a long time under the condition of high temperature and then guarantee the intensity of support, it makes central tube can be installed on securely cyclone separator inside, can not come off, guarantee the long-term stability operation of boiler.
