Description
Technical field
This utility model belongs to the cooling cyclone separator central tube in cyclone separator field, particularly CFBB.
Background technology
CFBB is wide with its fuel tolerance and the advantage such as environmental protection, is worldwide widely used.Have a large amount of solid particle to be formed at burner hearth → separator → burner hearth inside CFBB to circulate.Most of solid particle in gas-solid mixing flue gas, as gas-solid separator equipment, is separated return burner hearth by separator, and gas is then discharged from separator top exit (i.e. central tube upper end).Central cylinder of separator is the circular tube shaped parts stretching into separator interior certain depth from separator top down, its Main Function is exhanst gas outlet passage, isolation simultaneously has just enter into separator and is not fully complete the gas-solid mixing flue gas of gas solid separation, plays the effect improving separation efficiency, such as Fig. 1.
Circulating fluidized bed boiler separator central tube local environment is hot environment, generally higher than 800 DEG C, is susceptible to deformation and drops.Reason due to structure, (i.e. separator body is made up of cooling cyclone separator pipe, have the cooling mediums such as steam in pipe) central tube roll frequently with steel plate, owing to swell increment is different, central cylinder of separator can not be directly welded on separator pipe.The central tube fixed form of cooling cyclone separator was frequently with being hung on below separator outlet flue in the past, exhaust pass be outer surface be steel plate, inner side is lined with the structure of heat insulating refractory material, and central tube must be hung on the steel plate structure of separator outlet flue outer surface.The way used is an inverted cone cylinder on the set of central tube upper end, and cone cylinder upper end is connected with separator outlet flue, in the middle and upper part of cone cylinder, is coupled together with cone cylinder by central tube by horizontal connector, such as Fig. 2.Owing to there being high-temperature flue gas in central tube, central tube expanded by heating, cone cylinder is not heated, do not expand, central tube thermal expansion radially is hindered by cone cylinder, the position that central tube is connected with outside cone cylinder will produce bigger stress, in order to eliminate this thermal stress, need longitudinally to cut open some dilatation joints on central tube top.Expanding at dilatation joint in operation and tilt, deformation is serious, and the insulation material between central tube and cone cylinder comes off, and causes outside cone cylinder to burn red, increases heat and scatter and disappear, there is also potential safety hazard simultaneously.
Utility model content
The purpose of this utility model is: the deformation that often occurs for the central tube of current cooling cyclone separator of circulating fluidized bed boiler and burn red problem, a kind of central tube fixed structure is provided, in solving to run, red problem is burnt in central cylinder of separator deformation, improves separator reliability of operation and safety.
The purpose of this utility model is realized by following technical proposals:
A kind of support ear board-like central tube fixed structure being applied to cooling cyclone separator, including cooling cyclone separator and central tube thereof, central tube supports otic placode by several and is fixed on cooling cyclone separator, support otic placode one end to be fixed on central tube cylinder, the other end slides and is fixed on separator top, supports otic placode and radially can relative slide at central tube with separator top.
In this patent scheme, central tube cylinder expands along central tube cylinder radial direction together with supporting otic placode and shrinks, and central tube cylinder, without default dilatation joint, does not haves the metaboly produced because thermal expansion is obstructed yet.
As selection, also include the support ear base plate supporting otic placode, support otic placode and one top being fixed on central tube cylinder of support ear base plate thereof, other end is propped up on the force bearing plate of separator top pipe, support ear base plate offers bar shaped or hole, oval location in the area just above of force bearing plate, steady pin inserts this location Kong Bingyu force bearing plate and fixes, and support ear base plate can slide on force bearing plate relatively along hole, location.
As selection, one end that support otic placode is connected with central tube cylinder arranges several projections barrel through central tube cylinder, and projection is all fixing (the most firmly welding) in the inboard of the barrel of central tube cylinder and outside.The program increases structural strength and weld strength.
As selection, central tube cylinder is provided with thermal-insulation coat cylinder on the strong point at separator top, fills heat insulating refractory material between the interlayer between central tube cylinder and thermal-insulation coat cylinder.The program can reduce central tube and outwards dispel the heat, simultaneously because central tube is obstructed deformation and extruding problem to refractory material without thermal expansion, bottom this interlayer and both sides are the most seamless, and refractory material can keep firmly not dropping, and do not have the thermal-insulation coat cylinder red phenomenon of burning.
As selection, support otic placode along central tube circumferentially several.
As selection, central tube is cylinder.
As selection, being provided with the smoke impervious case of flexibility between central tube and cooling cyclone separator, and central tube inboard at smoke impervious case inserts the position of separator and is provided with flexible heat-insulating refractory material.
Aforementioned this utility model main formula case and each further selection scheme thereof can be with independent assortment to form multiple schemes; it is this utility model can use and claimed scheme: such as this utility model; selection can be with other and column selection combination in any; those skilled in the art can understand there is multiple combination according to prior art and common knowledge after understanding the present invention program; it is the claimed technical scheme of this utility model, does not do at this exhaustive.
The beneficial effects of the utility model: efficiently solve central cylinder of separator top and burn red problem with the deformation of exhaust pass connecting portion, reduce boiler heat and scatter and disappear, reduce maintenance workload, improve economy and the safety of operation.
