The multi-branch air supply and gas distribution triggering cabinet is provided with two air branches which are used under different working conditions, so that contact of a pulse generator, a nozzle inner wall and a flue with highly-corrosive gas is effectively reduced and the service life is prolonged; positions of an air intake and a mixed gas outlet are optimized, the corrosion of water on the inner wall of equipment to the equipment is reduced; meanwhile, a mixing igniter integrating a mixer and an ignitor is provided, so that the mixing volume is increased, the mixing uniformity is improved, and the igniting success rate is greatly improved; the production process is simplified and the production cost is reduced.
Description
Technical field
The utility model relates to pulse soot blower field, and especially a kind of distribution with many air branch road of new construction causes cabinet.
Background technology
In existing technology, in pulse soot blower field, it is indispensable that distribution causes cabinet.The version that the distribution of the outer air feed of great majority causes cabinet is different from our this outer air feed distribution initiation cabinet.The layout of internal unit and configuration etc. are different, mixed gas outlet position is different.
Because acetylene gas is a kind of organic gas.When burning, it can produce CO when (detonation)
2, heat and water.Because the temperature of boiler flue is higher, distribution initiation cabinet present position temperature is lower also can produce condensed water simultaneously.These water that are present in device interior are understood etching apparatus inwall, are stopped up the technical problems such as air-flow.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of distribution initiation cabinet that reduces equipment corrosion, improves many air branch road of ignition success rate.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of from air feed distributing cabinet, comprise cabinet, and be arranged on fuel gas pipeline and the blower fan in cabinet, fuel gas pipeline is by superposed acetylene branch road, be positioned at air one branch road and air two branch roads at middle part, and the gaseous mixture pipeline that is positioned at bottom forms, filter, acetylene magnetic valve and non-return valve are arranged on acetylene pipeline, magnetic valve one and needle valve one are arranged on air one branch road, magnetic valve two and needle valve two are arranged on air two branch roads, mixture pipe way outlet is arranged on cabinet bottom, combustion gas mixing igniter is set on gaseous mixture pipeline.
In such scheme, combustion gas mixing igniter comprises mixing chamber, is arranged on distributing damper, igniter hole and igniter in mixing chamber, and igniter hole is arranged on the wall on mixing chamber top, and igniter is arranged in igniter hole.
In such scheme, acetylene pipeline is provided with acetylene pressure gauge.
In such scheme, air one branch road and air two branch road front ends are merged into air header, and described air header is provided with air manometer.
In such scheme, acetylene pipeline is provided with spark arrester.
In such scheme, mixing chamber is tank shape structure.
Advantage and the good effect that the utlity model has are: distributing cabinet of the present utility model is provided with the air branch road that two different operating modes are used, and effectively reduce connecing of impulse generator, spout inwall and flue and highly corrosive gas dissatisfied, increase the service life; Optimize the position of getting air port and mixed gas outlet, improved the corrosion of the ponding of equipment inner wall to equipment; Be furnished with blender and the integrated mixing point firearm of igniter simultaneously, mix that volume increases, mixture homogeneity improves, ignition success rate significantly improves.Simplify production technology, reduced production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
In figure:
1, acetylene pressure gauge 2, filter 3, acetylene magnetic valve
4, non-return valve 5, air manometer 6, magnetic valve one
7, spark arrester 8, needle valve 1, air one branch road
10, magnetic valve 2 11, needle valve 2 12, air two branch roads
13, mixed gas outlet 14, mixing point cupping jar
The specific embodiment
The air header that the distribution that the utility model provides causes cabinet air feed is positioned at the middle part that distribution causes cabinet, and mixed gas outlet 13 is positioned at the bottom of cabinet.While entering air from outside from two different branch roads---air one branch road 9 and air two branch roads 12 enter system in different working hours.Mixed gas outlet 13 is in the bottom of cabinet, and the water that these burnings produce or condensed water just can not enter into the acetylene branch road on top and be positioned at the air branch road at middle part, can not erode to the inwall of equipment.
Acetylene pressure gauge 1 and spark arrester 7 on acetylene branch road, have been increased.When being convenient to debug, Pressure gauge sees the situation of change of looking into acetylene pressure.Spark arrester is a professional spark arrester, is not to be used for replacing spark arrester with the back-fire relief of filter, can more effectively prevent the generation of tempering, has increased the security of system.
On two-way air branch road, all configured needle valve, the discharge characteristic of these two needle valves is linearity or geometric ratio.Because the corresponding relation of its aperture and flow is comparatively fixing, the aperture of being convenient to adjust air valve is adjusted the flow of air, coordinates the Pressure gauge on air branch road to be convenient to debugging at the scene.Air one branch road is air feed when distribution causes cabinet work, provides the air that pressure versus flow is suitable to mix the suitable mist of generation concentration with acetylene.Air two branch roads are air feeds when distribution initiation cabinet quits work, and are designed with so several effects: dissatisfied the increasing the service life that connect that 1) reduces impulse generator, spout inwall and flue highly corrosive gas; 2) moisture content that is stored in device interior can be taken in flue and evaporates.
Before mixed gas outlet 13, are mixing point cupping jar 14 of a large volume.Because the volume of ignition jar is larger, water can be in the bottom of tank body.Igniter is arranged in the igniter hole on top of tank body, holding point firearm dry.And the water of pot bottom can blow out at explosion time.The increase of ignition jar volume, has extended closed electromagnetic valve to prefiring time delay.On 0.1～0.5 second original basis, increase again more than 0.2 second.At this moment, in section, gaseous mixture is diluted time lengthening, and the success rate of igniting improves.
The utility model can cause cabinet as general distribution to be used, also can be as being exclusively used in the comparatively special boilers such as metallurgical roasting furnace, incinerator, biomass boiler, cement industry waste-heat oven, glass furnace waste-heat oven.These boiler structures are more special, smoke gas flow complexity or flue gas corrosion is strong comparatively, particularly serious to spout and the corrosion of impulse generator tank body.The utility model is exactly mainly for above situation design.While quitting work, the air of low discharge can enter from air intake, by mixing point cupping jar, gaseous mixture pipeline, impulse generator tank body, spout to flue.The inwall of these equipment contacts with air.Reduced the contact of harmful smoke.Reduced the degree that equipment is corroded.Simultaneously because cost increases fewer.Also can be under general environment.
Above embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model scope and improvement etc., within all should still belonging to this patent covering scope.
