Description
Technical field
The present invention relates to a kind of for thermal power generation or thermoelectric boiler can automatic ash removing device, the system that especially a kind of boiler internal for thermal power plant, steam power plant can automatic ash removing.
Background technology
Prior art is source of the gas and energy momentum starter to the basic function parts only, can there be direct pipeline to be connected with the energy buffer by momentum starter, do not consider to cooperate between the pipeline functional part, cooperate between pipeline and the pipeline, and corresponding parameter cooperates, thereby, technique effect is generally very poor at present, the shock wave of radiation and air-flow effective range are very short, only have about 3m, can not satisfy large-scale far away, medium-sized boiler is removed the requirement of dust stratification, especially to the dead angle of boiler internal, lee face, remote dust stratification does not have effective means, and can not adjust the radiation shapes of shock wave air-flow, the strength retrogression is fast etc.Cooperatively interact with the size of mozzle and being connected of multistage pipeline cooperatively interacts such as air inlet pipe, and pass in and out pipeline and close cooperating of road energy momentum starter, the temporary container of energy, also has the further cooperation of regional parts pipeline, and the overall co-ordination of the whole pipeline of total system and functional part, do not given play to local cooperate, the advantage of overall co-ordination.
Summary of the invention
Native system is by two class sources of the gas, the pure combustion gas of one class, one class is that oxidant is the air source of the gas, connect separately respectively main line, main line connects one group of (1 to 100) main decommutator separately, the pure combustion gas that two class master decommutators are told divide pipeline and air divide pipeline by 1 pair 1 meet in groups close the road can momentum starter.Each converges and can connect one group of (1 to 100) gaseous mixture pipeline after the momentum starter, connect one group of (1 to 49) energy buffer and volume or the cross-sectional area that is equal at least significant end, in certain limit, buffer has mozzle, mozzle can be the pipe of any shape and cross-sectional area in certain limit, connecting line is in certain limit.
Technical problem: the formation point of gaseous mixture is at the rear portion of native system pipeline.Gas is through multistage Pipe transfer, especially the combustion gas road is very influenced, because the acetylene gas safe pressure that adopt usually on the combustion gas road is low, the Pipe transfer loss is very obvious, have a strong impact on the mixed effect at the energy momentum starter, and continue to transmit backward, often local detonation only occurs or the detonation energy is unstable in the energy buffer, fluctuated, and the success rate that kindling material transmits is low, also affect simultaneously gaseous mixture detonation energy and internal tank energy loss in the energy buffer, air-flow is derived efficient, shape finally affects range, width, the cleaning such as cleannes index.The fixed characteristic that common pipeline connects combustion gas is not utilized, the pipeline air-flow character is also out in the cold, make two kinds of gas mixing efficiencies not high, evenly effect is bad, easy igniting is Transmission in pipeline afterwards, and excessive in energy buffer self-energy loss consumption, energy releasing efficiency is not high, does not reach the effect of ideal dumping dust stratification.
Technique effect: native system adopts suitable pipeline to change combination, cooperate suitable energy buffer parameter can play in Pipe transfer as improving the gaseous mixture uniformity endways, and in closing road energy momentum starter, tentatively realize, in the even level of the continuous raising of transmission trunking thereafter, reduce the transmission pressure loss, in input energy buffer, finally reach perfect condition, cooperate particular container and mozzle parameter, the detonation energy and the intensity that realize the equal volume combustion gas are maximum, combustion gas detonation energy significantly reduces at the container internal consumption, the efficient that derives air-flow and shock wave improves and suitable shape, pass by the intensive tube bank ability of cleaning and strengthen, the cleaning distance, width increases, dead angle in the stove, and the lee face cleannes are obviously improved.
The inventor finds that through experiment one group of single or many, the pipeline of various shape, certain limit cross-sectional area can adjust the state of air-flow, and the flow rotation state that enters container, the temporary container of cooperation certain parameter energy can be adjusted the gaseous mixture concentrated area after gas enters container, this regional integral body is moved down, be conducive to discharge original air, and avoid significantly affecting the uniform state of gaseous mixture.When serving as mozzle and adopting certain parameter, the global shape of adjustment ejaculation air-flow, intensity distributions, effective range etc.1. cooperate main decommutator can reduce main shunt conversion progression, reduce unnecessary loss, for entering admixture, the lift gas SBR.2. close road energy buffer and use, the relation of flow rate adjustable and flow velocity, the shunt of offside density current amount, to stressing to slow down the shunt of pressure drop, offside rekindling success rate all can select to adopt respective combination realization purpose.
Suitable volume and external diameter or the energy buffer that is equal to cross-sectional area use can the Effective Raise detonation efficient, reduce the loss of detonation energy in container, cooperate the efficient that can effectively improve detonation energy and energy derivation with the mozzle of certain limit, make the air-flow global shape of ejaculation be suitable for removing the dust stratification dead angle of the lee face etc. of boiler internal heating surface or heat exchanger components, improve range, strengthen width, penetration capacity and cleannes improve.
Mozzle and certain shape, certain external diameter or the energy buffer that is equal to cross-sectional area, certain volume are used in conjunction with, can adjust intensity, airflow shaped, direction in the border of penetrating air-flow and the range, help to remove non-common dust stratification and dead angle for specific environment, and adjust and blown each regional current rate distribution in the heating surface, realize for emphasis, difficult point, at a distance dust stratification removing.
Main decommutator: connecting line can reasonably distribute, adopt suitable caliber, can slow down the pressure loss that is transferred gas, improve effective transfer efficiency, reduce adherent effect, reduce main shunt conversion quantity, and close road energy buffer and be used in conjunction with the running environment that can change control assembly on the pipeline such as control valve.When main decommutator source of the gas and close the road can momentum starter between the time, move behind the ignition location of gaseous mixture, the mixture pressure before lighting is descended.Suitable conversion, transfer conduit caliber, shape can be slowed down pressure loss or be kept stress level.
Fuel gas pipeline and air pipe line comprise combustion gas main line and minute pipeline, air maim and minute pipeline, and main line is between source of the gas and main minute converter and connect the two, and minute pipeline connects can momentum starter.Two class pipelines adopt suitable parameter can improve efficiency of combustion, ignition success rate, detonation effect etc.
Native system comprises source of the gas, closes road energy momentum starter, energy buffer, main decommutator, controller, connecting line, control cable etc., the external diameter that following examples are used, the order of connection, cross-sectional area, volume, highly, the length of side, wall thickness, the data such as gas collector type of quantity, progression, source of the gas type, Container Type, pipeline type, main decommutator are example data along separate routes, are not limited to following example data scope when practical application.
