Abstract
The utility model relates to a high-temperature resistant and wear resistant ceramic cyclone separator of a CFBB (circulating fluidized bed boiler), in particular to a high-temperature resistant and wear resistant ceramic cyclone separator of a CFBB. The cyclone separator comprises a hearth outlet flue, a cyclone and a center cylinder arranged in the cyclone, and the upper part of the center cylinder is connected with a horizontal flue; the cyclone comprises a ceramic inside lining, an insulating layer and a carbon steel housing, the horizontal flue is connected at the upper end of the center cylinder formed by ceramic components in the cyclone, and the horizontal flue is communicated with a vertical flue; the lower end of the cyclone is connected with a reefed pipe and a reefed valve and communicated with the lower part of a hearth; and the upper end of the hearth is connected with the hearth outlet flue and is in lateral communication with the cyclone. The utility model has the advantages of simple structure, relatively-higher temperature bearing property by the equipment, higher temperature resistance and wear resistance, oxidation resistance, anticorrosion, deformation prevention, long service life, and low cost, and is a cyclone separator widely applicable to CFBBs.
Description
Technical field:
The utility model relates to a kind of heat resistant and wear resistant and decreases ceramic cyclone separator of circulating fluidized bed boiler, decreases ceramic cyclone separator equipment especially for heat resistant and wear resistant on the CFBB.
Background technology:
At present, CFBB has powerful growth momentum as a kind of novel clean combustion technology equipment, and the employed cyclone separator central tube of CFBB is the heat-resisting alloy steel that contains elements such as Gao Ge, nickelic and silicon, manganese, and price is higher; The temperature that can bear is relatively low, and heat resistant and wear resistant decreases poor-performing, easily oxide etch, and service life is shorter; Cyclone separator whirlwind tube has heat-insulating and vapour cold type, and heat-insulating cyclone separator whirlwind tube is by the steel construction shell, in be lined with insulation material and castable refractory is formed; Vapour cold type cyclone separator whirlwind tube is made up of the steam heating surface.
Summary of the invention:
The purpose of this utility model, provide a kind of heat resistant and wear resistant and decrease ceramic cyclone separator of circulating fluidized bed boiler, it is to adopt heat resistant and wear resistant to decrease ceramic material to make cyclone separator, have hardness height, high temperature resistant, wear-resistant, corrosion-resistant, oxidation resistant performance, make the temperature that ceramic cyclone separator can bear on the CFBB be higher than its operating temperature far away, avoid the scaling loss and the distortion of ceramic cyclone separator parts, slow down wearing and tearing, improve service life, the cycle of operation of prolonged boiler, improve the utilization rate of boiler, reduce maintenance cost.
The utility model takes following technical scheme to realize, it is to be made of furnace outlet flue and whirlwind tube and central tube, in the whirlwind tube central tube is set, central tube top is connected with horizontal flue, the whirlwind tube is made up of with heat-insulation layer and carbon steel shell ceramic-lined, the central tube upper end of being made up of ceramic component of whirlwind tube inside connects horizontal flue, horizontal flue is communicated with vertical heating flue, whirlwind tube lower end connects refeed line and the returning charge valve is communicated with lower furnace portion, and the burner hearth upper end connects furnace outlet flue and whirlwind tube lateral communication.Ash-laden gas enters by the furnace outlet flue and carries out the flue dust separation in the whirlwind tube in the burner hearth, flue gas is through outside central tube and horizontal flue and the vertical heating flue discharge boiler, flue dust falls in the refeed line through the whirlwind tube bottom, enters in the burner hearth by the returning charge valve, participates in the burner hearth internal combustion once more.
Effect of the present utility model is simple in structure, and the temperature that equipment can bear is higher relatively, and it is higher that heat resistant and wear resistant decreases performance, oxidation and corrosion, not yielding, long service life, equipment cost is low, is widely used in the cyclone separator equipment on the CFBB.
