Abstract
The utility model discloses a central barrel of a cyclone separator of a circulating fluidized bed boiler. The central barrel comprises an inlet barrel body and an outlet barrel body, wherein the inlet barrel body and the outlet barrel body are eccentrically arranged; and a transition barrel body for connecting the inlet barrel body and the outlet barrel body into a whole is arranged between the inlet barrel body and the outlet barrel body. The radial size of the outlet barrel body is larger than that of the inlet barrel body, and the longitudinal contour line of the longitudinal section of the central barrel relative to the largest eccentric side of the outlet barrel body is a straight line parallel to the axis of the inlet barrel body. The central barrel disclosed by the utility model is high in smoke-dust separating efficiency and good in effect.
Description
Technical field
The utility model relates to the central tube of cyclone separator of circulating fluidized bed boiler.
Background technology
CFBB obtains fast development because of having advantages such as fuel tolerance is wide, load regulation rate is big, environmental benefit is superior.Cyclone separator is the important component part of recirculating fluidized bed pot, and it mainly acts on is that unburnt solid particle with in the boiler smoke separates with boiler smoke, turns back in the boiler through revert system and burns; Reach the purpose that improves boiler efficiency; And in the cyclone separator very important components be exactly central tube, traditional concentric type central tube: separative efficiency is low, the less flying dust of many particles can't separate; Directly enter into back-end ductwork; Not only caused waste, also strengthened the wearing and tearing of back-end surfaces, also environment has been produced simultaneously and pollute.
The utility model content
The technical problem that the utility model will solve is to above-mentioned deficiency, and the central tube of a kind of separative efficiency height, flue dust good separating effect is provided.
In order to solve the problems of the technologies described above, the utility model provides a kind of central tube of cyclone separator of circulating fluidized bed boiler of following structure, and its design feature is that central tube comprises inlet cylindrical shell and outlet cylindrical shell; The inlet cylindrical shell is provided with the outlet cylindrical shell is eccentric, is provided with the transition cylindrical shell that the two is connected as a single entity between inlet cylindrical shell and the outlet cylindrical shell; Inlet cylindrical shell and the isometrical setting of outlet cylindrical shell.
Be equipped with reinforcement on the barrel of said central tube.
The inlet cylindrical shell of the utility model is the entrance and the eccentric setting of outlet section employing of central tube with the outlet cylindrical shell; Make flue gas in cyclone separator, produce eddy current; Form a material concentration field more uniformly; Make cyclone separator obtain more recycle stock, improved the flue dust separative efficiency and the flue dust separating effect of cyclone separator, also improved coal-fired utilization rate accordingly.In addition, be equipped with reinforcement on the barrel of central tube, increased the intensity of central tube, under the washing away of high-temperature flue gas, be not easy distortion, make the long service life of central tube.
In sum, the advantage of the utility model is: simple in structure, the flue dust separative efficiency is high, effective.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further to specify:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the upward view of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, the central tube of cyclone separator of circulating fluidized bed boiler comprises inlet cylindrical shell 1 and outlet cylindrical shell 2; Inlet cylindrical shell 1 and outlet cylindrical shell 2 eccentric settings are provided with the transition cylindrical shell 3 that the two is connected as a single entity between inlet cylindrical shell 1 and the outlet cylindrical shell 2.Inlet cylindrical shell 1 can be isometrical with outlet cylindrical shell 2, but consider flue gas mobile unobstructed in central tube, preferably adopts the design of the radial dimension of outlet cylindrical shell 2 greater than the cylindrical shell 1 that enters the mouth.The central tube vertical section is the design that is parallel to the straight line of inlet cylindrical shell 1 axial line with respect to vertical outline line of outlet cylindrical shell 2 maximum eccentric sides, and its benefit is: it is more unobstructed that flue gas flows in central tube, reduced the impact to the central tube inwall; Flue gas forms eddy current under the stopping of central tube, flue dust is better separated.Be equipped with reinforcement 4 on the barrel of central tube, reinforcement 4 is preferably disposed on inlet cylindrical shell 1 and exports on the cylindrical shell 2.
Claims (2)
