Abstract
The utility model relates to a boiler slag-off device of a cycling fluidized bed, in particular to a structural arrangement way of a slag-off pipe of a slag-off device, which comprises fluidized bed slag, a fluidized bed hood, a water-cooling wall pipe, an expansion device and a lower collecting box, wherein the lower collecting box, the expansion device and the fluidized bed hood are connected with the water-cooling wall pipe to form an integral water-cooling wind box, and is characterized in that the water-cooling wall pipe is connected with a reducing slag-off pipe and passes through the water-cooling wind box; and the lower end of the reducing slag-off pipe is provided with a slag-off valve. The boiler slag-off device has simple, compact and reasonable structure, convenient manufacturing and easy application, can thoroughly solve the weakness that the slagging of the cycling fluidized bed boiler is not smooth at any time, can completely discharge the slag as long as the diameter of the slag is equal to or smaller than the caliber on the upper end of the reducing slag-off pipe, and not only can realize the manual discontinuous slagging, but also can realize the mechanical continuous slagging by accessing the reducing slag-off pipe to the inlet of a slag cooler according to the arrangement situation of the boiler house of the user.
Description
Technical field
The utility model relates to a kind of deslagging device of circulating fluidized bed boiler, specifically relates to the scum pipe structural arrangement form of its slag-draining device.
Background technology
Diameter is identical up and down for the scum pipe of regular circulation fluidized-bed combustion boiler slag-draining device, unfavorable deslagging or deslagging are not smooth, and CFBB is in playing furnace igniting or normal course of operation, owing to multiple reason all produces coking phenomenon inevitably, the coke button that produces is not of uniform size, under the situation of not blowing out, need to discharge smoothly, do not produce obstruction from the scum pipe of slag-draining device, especially all the more so when the accident deslagging.This not only brings adverse influence to the boiler operatiopn operation, also is difficult to regulate bed temperature, and the safety and economic operation of serious threat boiler can cause the ignition of the boiler failure simultaneously, wastes energy, and causes the accident.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, can realize CFBB at any time deslagging is smooth and easy thereby provide a kind of, reduces its interruption of service rate, guarantees the deslagging device of circulating fluidized bed boiler of safe and economical boiler stable operation.
The technical scheme that provides according to the utility model, deslagging device of circulating fluidized bed boiler comprises fluid bed slag, fluidized bed hood, water screen tube, expansion gear, next part case, and described next part case, expansion gear, fluidized bed hood and water screen tube are connected to a whole water cooled wind chamber of forming; Described water screen tube is connected with the reducing scum pipe and through water cooled wind chamber; The lower end of described reducing scum pipe is provided with residual cake valve.
Diameter was up-small and down-big when described reducing scum pipe was installed.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Easily manufactured, practicality is easily gone; Thoroughly solved the not smooth drawback of CFBB deslagging slagging at any time, as long as the clinker diameter is not more than the bore of reducing scum pipe upper end and can both absolutely discharges smoothly, boiler room deployment scenarios according to the user, can manually be interrupted deslagging and also the import of reducing scum pipe access slag cooler can be realized mechanical continuous discharging slag, effect is fine.
Description of drawings
Fig. 1 is the utility model structural front view.
Fig. 2 is that the utility model structure A is to view.
The specific embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
As Fig. 1～shown in Figure 2, comprise fluid bed slag 1, fluidized bed hood 2, water screen tube 3, expansion gear 4, reducing scum pipe 5, residual cake valve 6, next part case 7 and water cooled wind chamber 8.
The utility model adopts reducing scum pipe 5 to be connected with water screen tube 3 and through water cooled wind chamber 8; Diameter was up-small and down-big when described reducing scum pipe 5 was installed, and a residual cake valve 6 is set in the lower end of reducing scum pipe 5 and is connected with it; Described next part case 7, expansion gear 4, fluidized bed hood 2 are connected to a whole water cooled wind chamber 8 of forming with water screen tube 3.
The reducing scum pipe 5 of the utility model deslagging device of circulating fluidized bed boiler, it has utilized under the situation that focuses on no any frictional resistance certainly of material fluid bed slag 1 has been discharged for 5 li smoothly from the reducing scum pipe, stoker operating personnel are as long as manually be interrupted deslagging in real time according to burning in circulating fluid bed boiler chamber bed layer pressure parameter, and the aperture of perhaps adjusting residual cake valve 6 realizes the mechanization continuous discharging slag.
The utility model has not only brought convenience to boiler operatiopn operation, simultaneously to the quick adjustment bed temperature, carries out the accident deslagging and has played satisfied effect, can improve safe and economical boiler stable operation, the incidence of minimizing accident, but also energy savings simultaneously.
