Background technique
In field of garbage disposal, generally burnt using incinerator, wherein fire grate be conveying material by it is dry,
It is pyrolyzed, the important mechanism of combustion phases, wherein dryer section and pyrolysis section need to keep anoxic, anaerobic state, to inhibit nuisance
Matter generates, and burning zone needs to keep oxygen-enriched state, to guarantee full combustion, it is therefore desirable to accurately control burner hearth oxygen content.In addition,
Material just can guarantee fully reacting and do not influence treatment effeciency by the opportunity stringent control of palpus in each stage.
The controllability of existing fire grate is poor, and material blanking velocity and oxygen-supplying amount control are inaccurate, causes efficiency of combustion low, fires
Burn insufficient, urgent need solution.
Summary of the invention
The purpose of the present invention is to provide a kind of fire grate structures, in view of the above-mentioned problems, optimization fire grate structure, improves fire grate
Control ability meets various burning needs.
In order to achieve the above object, the invention adopts the following technical scheme:
A kind of fire grate structure comprising dryer section fire grate, pyrolysis section fire grate and the burning zone fire grate successively accepted, each section of furnace
The lower section setting of row is provided with the air feed system of combustion oxygen, and each section of fire grate is controlled by independent drive system, each section of fire grate
Top be provided with exhaust gas volumn detector, air feed system includes main air duct and multiple points of air ducts, and each point of air duct and each fire grate are one by one
Corresponding, the exit in each point of air duct is provided with oxygen content testing instrument, and the entrance in each point of air duct is provided with Boiler pressure control valve, drives
Dynamic system includes the corresponding telescopic cylinder for controlling each fire grate blanking velocity, the output rod of telescopic cylinder and the movable furnace grate plate of fire grate
It is drivingly connected, to control its stroke, moves back and forth.
It wherein, further include controller, oxygen content testing instrument, exhaust gas volumn detector are communicated to connect with controller, air quantity control
Valve processed, telescopic cylinder are controlled with controller and are connected, control Boiler pressure control valve folding, so that oxygen content reaches target in furnace
Setting value, when detecting exhaust gas volumn deficiency, control blanking velocity slows down, and extends residence time of material.
Wherein, dryer section fire grate, pyrolysis section fire grate oxygen content target set point be 6%~10%, burning zone fire grate
Oxygen content target set point is 18%.
To sum up, beneficial effects of the present invention are that compared with prior art, the fire grate structure is by being segmented fire grate
Design, and then the volume of air supply and blanking velocity of each section of fire grate are controlled, and adjust according to different combustion state adaptability, to guarantee
Material full combustion on each fire grate.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of fire grate structure provided in an embodiment of the present invention.
Specific embodiment
To further illustrate the technical scheme of the present invention below with reference to the accompanying drawings and specific embodiments.
Refering to Figure 1, the present embodiment provides a kind of fire grate structures comprising the dryer section fire grate 1 successively accepted, heat
