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, more particularly to one kind are circulated using tank car The system that bed materials of fluidized bed boiler adds.
Background technology
Recirculating fluidized bed, need to be repeatedly to bed be added in burner hearth, to meet in unit starting or when carrying out aerodynamic field and testing 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:One feed bin of configuration, installs a table scale pipe apron feeder, gives under feed bin Connect 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, for controlling bed to enter 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, has had influence on normal job schedule.Additionally there are system investments big, Complex structure and problem difficult in maintenance.
Content of the invention
The invention provides a kind of bed material adding system of circulating fluid bed boiler, solves circulating fluidized bed boiler bed material and adds The investment that adding system is present is big, complex structure and technical problem 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 stone Limestone flour transfer pot, is provided with boiler manhole on circulating fluid bed boiler body, connects on the top of agstone transfer pot There is compressed air delivery hose, the other end of compressed air delivery hose is connected together with compressed air cylinder, in agstone The bottom of transfer pot is connected with bed conveyance conduit, arranges on the other end of bed conveyance conduit and circulating fluid bed boiler body Boiler manhole be connected together.
The second compressed air delivery hose is provided between bed conveyance conduit and compressed air delivery hose.
The present invention takes full advantage of the lime stone 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.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
Specific embodiment
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 3,1 and of compressed air cylinder Agstone transfer pot 2, is provided with boiler manhole 6 on circulating fluid bed boiler body 3, on the top of agstone transfer pot 2 End is connected with compressed air delivery hose 4, and the other end of compressed air delivery hose 4 is connected together with compressed air cylinder 1, The bottom of agstone transfer pot 2 is connected with bed conveyance conduit 7, the other end of bed conveyance conduit 7 and recirculating fluidized bed pot The boiler manhole 6 arranged on furnace body 3 is connected together.
The second compressed air delivery hose 5 is provided between bed conveyance conduit 7 and compressed air delivery hose 4.This The conveying power of system is provided by station-service compressed air, as tank car is in zero meter of boiler room, about 12 meters of 6 height of boiler manhole, is Ensure sufficient power, at the startup pump discharge of tank car, and the elbow in 7 uphill process of bed conveyance conduit and conveying are hung down Straight section, installs compressed air gas supplementing opening additional to increase conveying power.
