Description
Technical field
The present invention relates to belong to CFBB material-returning device field, be specially a kind of material returning device bellows structure.
Background technology
Along with country's requirement increasingly stringent to pollutant emission, the demand of clean energy technology is also stepped up by station boiler and Industrial Boiler, Combustion technology of circulating fluidized utilizes technology as the low-grade fuel clean and effective burning of a kind of advanced person, of increased attention, and fast development has been obtained in recent years.
Material-returning device is the important component part of Materiais for CFB Boilers cyclic process, its Main Function is to send the fluidisation of isolated a large amount of high-temp solid materials from separator back to burner hearth, maintain the fluidized state of burner hearth, adjust fire box temperature, ensure fuel and desulfurizing agent repeatedly circulates, repeatedly burn and react, reach preferable efficiency of combustion and desulfuration efficiency.
Can the cloth wind performance of material-returning device normally loopback by the recycle stock directly affecting CFBB; and material returning device bellows structure is the vitals affecting material-returning device cloth wind performance; therefore; the quality of material returning device bellows design directly influences the properly functioning of CFBB, is very important to CFBB.
Chinese utility model patent 201520286633.3 reports a kind of CFBB material-returning device, have employed two the returning charge blower fans different from the conventional recycle fluidized-bed combustion boiler material-returning device single returning charge blower fan isolated operation mode method of operation simultaneously, increase the range of accommodation of returning charge blower fan, returning charge ash is prevented to pile up at material-returning device, avoid material-returning device coking, but it is big that its shortcoming is returning charge blower fan power consumption, adds operating cost, causes unnecessary loss.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides a kind of material returning device bellows structure, it takes into account economy while can solve the problem that recirculating fluidized bed material-returning device dust deposition problem, and returning charge is effective, and simple in construction.
Its technical scheme is such that a kind of material returning device bellows structure, it is characterized in that, it includes bellows body, described bellows body includes loosening air compartment, flowing air compartment and returning charge air compartment, described flowing air compartment is arranged between described loosening air compartment and described returning charge air compartment, described loosening air compartment is arranged in separator ash port side, described returning charge air compartment is arranged in burner hearth side, described loosening air compartment, flowing air compartment and returning charge air compartment all have air-vent and ash port, described air-vent connects induced duct, and described ash port connects ash tube.
It is further characterized by, and described air-vent is arranged in described loosening air compartment, flowing air compartment and the sidewall of returning charge air compartment, and described ash port is arranged in described loosening air compartment, flowing air compartment and the bottom of returning charge air compartment；
