Abstract
The invention relates to the field of urban household waste incineration, in particular to a speed control device and method for fire grates of a waste incinerator. The speed control device comprises a pusher, the drying fire grate, the combustion fire grate, the after-combustion fire grate, a distributed control system and a hydraulic flow control valve. The pusher determines operating speed according to the waste treatment capacity compiled into the distributed control system, controls the layer thickness of waste according to the speed of the drying fire grate and the speed of the combustion fire grate and controls the speed of the combustion fire grate and the speed of the after-combustion fire grate according to the temperature of the top of the after-combustion fire grate, so that the heat igloss rate is minimum.
Description
Technical field
The present invention relates to burning city domestic garbage field, transmit bed speed control unit and method thereof in especially a kind of burning city domestic garbage processing.
Background technology
The fast development and the urbanization process that are accompanied by China's economic are constantly accelerated, and industrial refuse and house refuse problem have become the bottleneck of restriction urban development.How administering these discarded objects has become the pendulum important topic that urgent need solves in face of us, and existing garbage disposal mainly contains the modes such as sanitary landfills, compost, burning, waste recovery.These several processing modes all respectively have its pluses and minuses, wherein burning disposal have decrement successful, innoxious thoroughly, little, the recoverable energy of occupation of land amount is for for advantages such as heat and generating powers, meet the requirement of China's strategy of sustainable development, be just day by day subject to people's attention.Incinerator comes the effect of playing combustion refuse, mobile rubbish in incineration treatment of garbage.Moisture in dry fire grate evaporation rubbish, combustion grate combustion refuse, burn-out grate completing combustion rubbish.Effective control to the garbage incinerator fire grate speed of service, be beneficial to system continuously, smooth combustion.
The applicant is at the disclosed CN102927573A of first to file, and name is called the patent documentation of one way of life incinerator automatic combustion control system, though fire grate speed control parameter is had to description, control method more specifically not yet disclosed.
Summary of the invention
The present invention proposes a kind of garbage incinerator grates speed control unit, comprises pusher, dry fire grate, combustion grate, burn-out grate, dcs and hydraulic flow control valve; Pusher is determined the speed control rubbish bed thickness of the speed of service, dry fire grate and combustion grate according to the garbage treatment quantity that enrolls dcs, according to the temperature control combustion fire grate at burn-out grate top and the speed of burn-out grate, reach hot burn decrement rate minimum.
Further, the present invention's one a kind of garbage incinerator grates method for control speed in place, equipment comprises pusher, dry fire grate, combustion grate, burn-out grate, dcs and hydraulic flow control valve; Described pusher is determined the speed control rubbish bed thickness of the speed of service, dry fire grate and combustion grate according to the garbage treatment quantity that enrolls dcs, according to the temperature control combustion fire grate at burn-out grate top and the speed of burn-out grate, reach hot burn decrement rate minimum.
Further, the pusher speed of service claims simple DCS by dcs Distributed Control Systems() enroll garbage treatment quantity and survey gained rubbish bed thickness and determine.
Further, pusher and each fire grate speed are controlled and are realized by hydraulic flow control valve.

Wherein:
1-pusher; 2-dry fire grate; 3-combustion grate; 4-burn-out grate; 5-DCS; 6-hydraulic flow control valve.
The specific embodiment
The present invention proposes a kind of garbage incinerator grates speed control unit and method thereof, comprises pusher 1, dry fire grate 2, combustion grate 3, burn-out grate 4, DCS5 and hydraulic flow control valve 6.Pusher 1 is determined the speed of service according to the garbage treatment quantity that enrolls DCS5, and the speed of dry fire grate 2 and combustion grate 3 is controlled rubbish bed thickness, according to the temperature control combustion fire grate 3 at burn-out grate 4 tops and the speed of burn-out grate 4, reaches hot burn decrement rate minimum.
Pusher 1 speed of service is enrolled garbage treatment quantity by DCS5 and is surveyed gained rubbish bed thickness and determine.
By rubbish bed thickness, control dry fire grate 2 speed.
According to the temperature control combustion fire grate 3 at burn-out grate top and the speed of burn-out grate 4.
Pusher 1 and each fire grate speed are controlled and are realized by hydraulic flow control valve 6.
By measuring combustion chambers burn fire grate 3 and leaking the rubbish thickness on the different differential pressure measurement fire grates that measure in slag bucket.Measurement point should arrange 2 in the measurement of incinerator.
The garbage treatment quantity that enroll according to DCS5 at the interval of fire grate operation calculates, and each operation interval is controlled automatically according to setup parameter, even if rubbish quality and combustion position change like this, still can keep smooth combustion.
Thermocouple is installed in a plurality of places at combustion grate 3 upstream and downstreams, measures the temperature of fire grate segment in combustion process, detects the combustion heat impact of fire grate segment.In combustion process, if send combustion high temperature alarm signal, burning should slow down or with cooling the avoiding of combustion air, fire grate be caused to fire damage.
