Description
Technical field
The utility model relates to Sector of Cfb Boilers, is specially a kind of blast cap adapter fixed structure for CFBB.
Background technology
Recirculating fluidized bed (CFB) boiler is high efficiency, low stain and the good coal combustion technology fully utilized that the eighties grows up, due to the unique advantage that it has on coal adaptability and varying duty ability and reduction pollutant emission, it is made to be developed rapidly.
The fluidization hood adapter of current CFBB adopts Type of Welding to be fixed on burner hearth air distribution plate, and as shown in Figure 1, blast cap adapter is installed on circular hole place to air distributor structure, after installation as shown in Figure 2, wherein 1 is air distribution plate, and 2 is blast cap adapter, 3 is castable, and 4 is blast cap head.Circulating fluidized bed boiler is developed so far, and multiple pattern (arrow type, bell jar, ring etc.) appearred in fluidization hood, but its adapter pattern does not change to some extent, all adopts Site Welding form.The blast cap quantity of present stage 220t/h circulating fluidized bed boiler is about 850, and the blast cap quantity of 480t/h circulating fluidized bed boiler is about 2100, and the workload that building site is installed is very large, and installation quality is also very different.
In addition, fluidization hood and the residing environment of adapter are high temperature, high eroded area, and need regularly safeguard as consumable accessory, as found, damage need be changed in time.Blast cap head 4 is changed relatively simple, only need to take off damage, change new blast cap head 4.Blast cap adapter 2, owing to being be welded on air distribution plate 1, so dismounting very loaded down with trivial details time-consuming (can not hurt air distribution plate 1), is unfavorable for boiler rapid-maintenance.
Summary of the invention
In order to solve the problem, the utility model provides a kind of blast cap adapter fixed structure for CFBB, and its structure installment is simple, ensures construction quality, and examine and replace is convenient.
Its technical scheme is such: a kind of blast cap adapter fixed structure for CFBB, it comprises blast cap adapter, described blast cap adapter is installed on described air distribution plate, it is characterized in that, described blast cap adapter comprises blast cap adapter epimere and blast cap adapter hypomere, described blast cap adapter epimere lower end has internal thread hole, described internal thread hole outer end arranges support rim, described blast cap adapter hypomere upper end arranges the external screw thread coordinated with described internal thread hole, the described blast cap adapter hypomere of described external screw thread lower end arranges lower support boss, described blast cap adapter epimere, blast cap adapter hypomere is by described internal thread hole, externally threaded being threaded makes described upper support rim, lower support boss compresses described air distribution plate.
It is further characterized in that, installs packing ring between described lower support boss and described external screw thread;
The described internal thread hole degree of depth, external thread length are 50mm to 70mm.
After adopting structure of the present utility model, blast cap adapter is divided into blast cap adapter epimere and blast cap adapter hypomere, only need blast cap adapter hypomere during in-site installation through air distribution plate, lower support boss props up air distribution plate lower end, blast cap adapter epimere is tightened in blast cap adapter hypomere, upper support rim props up air distribution plate upper end, blast cap adapter is fixed on air distribution plate, structure installment is simple, avoids on-the-spot welding job, ensures construction quality, during examine and replace, easy accessibility, can not damage air distribution plate, improves overhaul efficiency.

Fig. 2 is prior art Apoplexy cap adapter fixed structure;
Fig. 3 is the utility model Apoplexy cap adapter fixed structure;
Fig. 4 is the utility model Apoplexy cap joint pipe structure.
Detailed description of the invention
See Fig. 3, shown in Fig. 4, a kind of blast cap adapter fixed structure for CFBB, it comprises blast cap adapter 2, blast cap adapter 2 is installed on air distribution plate 1, blast cap adapter 2 comprises blast cap adapter epimere 5 and blast cap adapter hypomere 6, blast cap adapter epimere 5 lower end has internal thread hole 5-1, internal thread hole 5-1 outer end arranges support rim 5-2, blast cap adapter hypomere 6 upper end arranges the external screw thread 6-1 coordinated with internal thread hole 5-1, the blast cap adapter hypomere 6 of external screw thread 6-1 lower end arranges lower support boss 6-2, blast cap adapter epimere 5, blast cap adapter hypomere 6 is by internal thread hole 5-1, being threaded of external screw thread 6-1 makes support rim 5-2, lower support boss 6-2 compresses air distribution plate 1, blast cap head 4 is installed on the upper end of blast cap adapter epimere 5, blast cap head 4 sidepiece has fluidized wind outlet, 3 is castable, blast cap adapter hypomere 5 is through air distribution plate 1, lower support boss 6-2 props up air distribution plate 1 lower end, blast cap adapter epimere 5 is tightened in blast cap adapter hypomere 6, upper support rim 5-2 props up air distribution plate 1 upper end, blast cap adapter 2 is fixed on air distribution plate 1, fluidized wind enters from the lower end of blast cap adapter hypomere 6, export away from fluidized wind through after blast cap adapter hypomere 6 and blast cap adapter epimere 5, packing ring 7 is installed between lower support boss 5-2 and external screw thread 6-1, packing ring 7 can avoid being threaded between leak out, improve sealing further, the internal thread hole 5-1 degree of depth, external screw thread 6-1 length are 50mm to 70mm, it is too short that cannot to realize between blast cap adapter epimere 5 and blast cap adapter hypomere 6 compared with ground fixing, be fixedly connected with although oversize more firm, affect installation effectiveness, also increase equipment cost simultaneously.
