Description
Affiliated technical field
The invention belongs to the boiler pulse soot-blowing technical field, be specifically related to the efficient mixing initiator that a kind of soot blower is used.
Background technology
Pulse soot blower has another name called blast wave blower, be the earliest by the scientific and technical personnel of Ukraine in last century the eighties propose at first, mainly be that the premix gas that fuel and combustion-supporting gas are formed explodes in the blast jar internal combustion that is communicated with flue by jet pipe, by percussion and the souring removing heat-transfer surface of high-speed jet and the dust stratification of flue wall of explosion wave.Domestic then from last century the nineties begin development because ash-removal effect is good and can remove the intractable black dirt, develop very rapid.
Existing blast wave blower all is to adopt air as combustion-supporting gas, fuel also adopts gaseous fuel mostly, thereby all need fuel gas and air are placed in the segment pipe, laminar flow becomes turbulent flow and obtains uniform burning mixture when making it reach certain flow rate, and the mixture homogeneity of this blender is relatively poor.
Summary of the invention
The objective of the invention is to: the efficient mixing initiator that provides a kind of soot blower to use, blender in the past is according to the hydrodynamics Reynolds number, laminar flow becomes turbulent flow and obtains mist when gas reaches certain flow rate in a segment pipe, compared with the prior art, when making gas flow rate not reach Reynolds number, it just can become turbulent flow, two kinds of gases can fully mix, and its volume is little and degree of being mixed into is very good.
The present invention program is: the efficient mixing initiator that a kind of soot blower is used; Mainly comprise: location end cap (1), air inlet pipe (2), admission line (3), distributing damper (4), back-up ring in the import (5), shell (6), back-up ring under the import (7), back-up ring (8), afflux baffle plate (9), discharge (10), back-up ring (11), back-up ring in the outlet (12), lower baffle plate (13), outlet is back-up ring (14) down, escape pipe (15), igniter (16), mounting flange (17), fuel gas gas outlet (18), collection blender and igniter are one.
The present invention is characterized in that: be respectively equipped with admission line (3) and discharge (10) in distributing damper (4) and lower baffle plate (13) top and make that air communication is out-of-date clashes into overhead gage (4) and lower baffle plate (13) formation twice are broken up air-flow all around by middle mind-set passage respectively; Be provided with distributing damper (4) in admission line (3) below and be provided with the twice annular air-flow path that lower baffle plate (13) forms with shell (6) respectively in discharge (10) below; Be provided with discharge (10) in distributing damper (4) below and be provided with escape pipe (15) and form twice respectively to the concentrated airflow flowing passage in center in lower baffle plate (13) below; Air inlet (2) is that gas thread connects, and gaseous mixture gas outlet (18) are connected by ring flange.
Major advantage of the present invention is:
1. mixture homogeneity is more effective than existing blender, evidence, and compared with the prior art the mixture homogeneity of this mixed method and device improves a lot;
2. very high owing to mixture homogeneity, the no carbon distribution of the electric igniter of blast wave blower, longer service life is safeguarded simpler;
Since mixture homogeneity improve, under the constant prerequisite of other condition, fuel saving gas more, the intensity that the gaseous mixture blast is produced is also higher;
4. the similar relatively mixing point firearm of the present invention deft design is simple and practical, and convenient processing and manufacture is fit to produce in batches.Description of drawings: the utility model is provided further instruction below in conjunction with drawings and Examples.
Fig. 1 is the cross-sectional schematic that invention is implemented, among the figure: location end cap (1), air inlet pipe (2), admission line (3), distributing damper (4), back-up ring in the import (5), shell (6), back-up ring under the import (7), back-up ring (8), afflux baffle plate (9), discharge (10), back-up ring (11), back-up ring in the outlet (12), lower baffle plate (13), outlet is back-up ring (14) down, escape pipe (15), igniter (16), mounting flange (17), fuel gas gas outlet (18), air inlet (2) is that gas thread connects, and gaseous mixture gas outlet (18) are connected by ring flange.
The specific embodiment
Fuel gas and air are under laminar condition, clash into upward distributing damper (4) earlier through air inlet (2), gas disperses to strike back-up ring in the import (5) to all around, upwards strike upper shell (6), strike afflux baffle plate (9) downwards, back-up ring (7) under the bump import of inwardly flowing, strike afflux baffle plate (9) downwards again, inwardly flow and clash into discharge (10), bump is gone up distributing damper (4) again, and gas clashes into mutually when center flow; Strike down distributing damper (12) downwards, gas is gone up back-up ring (11) to disperseing to bump against outlet all around again, gas upwards strikes afflux baffle plate (9) again, gas upwards strikes afflux baffle plate (4), outwards bump against housing (3), gas bumps against outlet (15) upper end external diameter downwards along housing, it is suitable for reading that upwards gas strikes down distributing damper arrival escape pipe again, gas is concentrated percussion mutually again, having passed through the bump of being rebuffed for 16 times during point of arrival firearm (16) hits with 2 second phase knocks against each other, force gas to become turbulent flow by laminar flow, turbulent flow is rebuffed and is formed turbulent flow again, makes the fuel gas of process mixing point firearm can mix very evenly with air.
Test proof nearly ten thousand times, ignition success rate is high, reaches 100%, and the detonation power is big, and more fuel saving gas is minimum to the ignition success rate influence when fuel gas of input has pressure oscillation.
