Detailed description of the invention
Below in conjunction with Figure of description, the present invention is described in further detail:
A kind of two-way anaerobic type energy-saving biomass boiler, including the first regenerator 1 and the second regenerator 2, first regenerator 1 one end is connected with the first air inlet pipe 3, and the other end is connected to combustor 4；Second regenerator 2 one end is connected with the second air inlet pipe 5, and the other end is connected to combustor 4.Combustor 4 both sides sidewall is provided with nozzle 6, and nozzle 6 connects the first regenerator 1 and the second regenerator 2 respectively, and the number of every side nozzle can have multiple, preferably three, uses resistant to elevated temperatures metal material, preferably rustless steel.Being provided with reversal valve 7 between first air inlet pipe 3 and the second air inlet pipe 5, for displacement gas flow path direction, be mixed into trachea 8 one end and connect compressor 9, the other end is connected to flue 10 through reversal valve 7.
Reciprocating fire grate 11 it is provided with bottom combustor 4, reciprocating fire grate 11 is driven by reciprocating motor, first regenerator 1 outlet is provided with the first switching valve 12, second regenerator 2 outlet is provided with the second switching valve 13, the first described reversal valve 12 and the second reversal valve 13 carry out master control by control valve 14, are used for realizing the control of both sides burning work.Flue 10 is provided with air-introduced machine 15, is discharged by flue by flue dust by air-introduced machine, and the present invention is additionally provided with air relief valve, uses safer.
Operation principle: normal temperature air enters the first regenerator by air compressor, the temperature set it is heated to together with tiny stalk particle, meanwhile, first switching valve is opened, fuel enters from charging aperture, air, stalk particle is sprayed by nozzle together with the mixture of fuel, because stalk particle material is lighter, combustion property is good, in a combustion chamber, major part can the most aloft fully be burnt by heat smoke, only a few can not clean-burning be fallen on reciprocating fire grate, carry out second-time burning, after burned, low-temperature flue gas is discharged by air-introduced machine from flue by reversal valve.The regenerator on both sides carries out accumulation of heat and heat release alternation with certain frequency; the when of alternately to other end work; control valve controls the switching valve of the other end and opens; reversal valve commutates; compressed air is pressed into respective end; reciprocating motor controls fire grate and moves to another side, for accepting air, fuel and the stalk particle mixture from the ejection of other end nozzle.In the present invention, control valve can control, by electromagnetic relay, the effect that start and stop reach Tong Bu with reciprocating fire grate.
The two-way anaerobic type energy-saving biomass boiler of the present invention, after normal temperature air is entered boiler by compressor compresses, it is heated in heat storage together with stalk particle, produce temperature and reach the high-temperature hot flue gas of 800-1000 degree, oxygen deprivation non-flaming combustion stalk particle, save the energy, and reduce discharge nitrogen oxides more than 40%, greatly reduce the pollution to environment.
