Description

Bed material adding system of circulating fluid bed boiler
Technical field
The present invention relates to a kind of bed material adding system of circulating fluid bed boiler, utilize tank car to be circulated particularly to one The system that bed materials of fluidized bed boiler adds.
Background technology
Recirculating fluidized bed, at unit starting or when carrying out aerodynamic field test, need to repeatedly be given and add bed in burner hearth, to meet When boiler startup and test, the requirement of different-thickness bed.At present, the CFBB of domestic operation is each equipped with bed Add-on system.General bed add-on system is: configure a feed bin, installs a table scale pipe apron feeder, give under feed bin Connecting two-stage scraper machine after material machine, scrapper conveyor is equipped with feed opening on corresponding every feeder, and each material inlet has Controllable register door, is used for controlling bed and enters the discharge quantity of every feeder, when bed is added often due to weigh belt-type to The belt deviation of material machine, causes feeding system to stop transport, and has had influence on normal job schedule.Additionally there are system investments big, The problem that structure is complicated and difficult in maintenance.
Summary of the invention
The invention provides a kind of bed material adding system of circulating fluid bed boiler, solve circulating fluidized bed boiler bed material and add The investment that adding system exists is big, the technical problem that structure is complicated and difficult in maintenance.
The present invention is to solve above technical problem by the following technical programs:
A kind of bed material adding system of circulating fluid bed boiler, including circulating fluid bed boiler body, compressed air cylinder and limestone Powder transfer pot, is provided with boiler manhole on circulating fluid bed boiler body, and connecting on the top of agstone transfer pot has pressure Contracting air delivery hose, the other end of compressed air delivery hose is connected together with compressed air cylinder, carries at agstone The bottom of tank connects bed conveyance conduit, the other end of bed conveyance conduit and the pot of setting on circulating fluid bed boiler body Stove manhole is connected together.
The second compressed air delivery hose it is provided with between bed conveyance conduit and compressed air delivery hose.
The present invention takes full advantage of the limestone conveying tank car of power plant, and charging system is simple, simple to operation, can be reliable Guarantee feeds, and everything goes well with your work is carried out.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
The present invention is described in detail below in conjunction with the accompanying drawings:
A kind of bed material adding system of circulating fluid bed boiler, including circulating fluid bed boiler body 3, compressed air cylinder 1 and Calx Stone powder transfer pot 2, is provided with boiler manhole 6 on circulating fluid bed boiler body 3, on the top of agstone transfer pot 2 even Being connected to compressed air delivery hose 4, the other end of compressed air delivery hose 4 is connected together with compressed air cylinder 1, at Calx The bottom of stone powder transfer pot 2 connects bed conveyance conduit 7, and the other end of bed conveyance conduit 7 is with CFBB originally The boiler manhole 6 arranged on body 3 is connected together.
The second compressed air delivery hose 5 it is provided with between bed conveyance conduit 7 and compressed air delivery hose 4.This The conveying power of system is provided by station-service compressed air, owing to tank car is zero meter, boiler room, and boiler manhole 6 the most about 12 meters, for Ensureing sufficient power, at the startup pump discharge of tank car, and the elbow in bed conveyance conduit 7 uphill process and conveying are hung down Straight section, installs compressed air gas supplementing opening additional to increase conveying power.
