Abstract
The utility model discloses a special rotatory ejection of compact return bend of ebullated bed biomass pellet boilers, it is made by the tubular product that becomes bending angle, this special rotatory ejection of compact return bend of ebullated bed biomass pellet boilers can avoid appearing granule nonuniform distribution, the granule in heaps, in the granule in heaps the oxygen suppliment not in place, influence granule combustion efficiency's the condition, make in grains uniformly dispersing gets into the boiler, reach the high -temperature low -oxygen combustion effect and make the abundant complete combustion of fuel, reach smokeless micronic dust effect, be ebullated bed biomass pellet boilers's important composition part.
Description
Technical field:
The utility model relates to medium-and-large-sized biomass boiler, particularly a kind of ebullated bed biomass granule boiler Special rotaryDischarging elbow.
Background technology:
China is about 1/3 of national coal consumption total amount because of the annual coal consumption of Industrial Boiler at present, is caused by coal-burned industrial boilerEnvironmental pollution very serious, but due to the restriction of electric power, natural gas supply and gas pipeline each side, cannot be by ChinaCoal-burning boiler all changes electric boiler or gas fired-boiler into, more easily makes user and the price of biomass boiler is low and operating cost is lowAccept and widelyd popularize; At present, known Horizontal type fast biomass granule boiler is traveling-grate stoker, its shortcoming: (1) chainWhen boiler operatiopn, user is on-the-spot by vapour size adjustment difficulty, although adjustable gate and adjusting fire grate speed need oneThe fixed time just can regulate, and on-the-spot steam consumption regulating frequency is more frequent, has increased operating difficulties to fireman, has wastedFuel and not energy-conservation, has increased operating cost; (2) traveling-grate stoker is in the time of operation, and scene needs the short time to stop steam supply with vapour, andWhen temporary transient blowing out, the exhaust emission environment that produces thick smoke again, in the time that blowing out exceedes 15 minutes, its fuel is very easy to be tempered to materialBucket, when as more in hopper material stock, also easy breaking out of fire; (3) traveling-grate stoker combustion system is grate firing type, and the thermal efficiency generally exists73% ~ 75% left and right, can not reach national energy-saving standard; Known boiler has overhead chimney emission, and it installs difficulty, and costHigh; This ebullated bed biomass granule boiler thermal efficiency is high, and energy-saving effect is remarkable, and simple, convenient reliable, effectively separatesShortcoming and disadvantage that the above chain-grate boiler of having determined exists; (4) feeding that in existing boiler technology, more than 2 tons biomass boiler adoptsDevice generally all adopts many charging lines that biological particles is delivered to burner hearth bottom fixed position, and this mode exists particle to divideThe situation that cloth is inhomogeneous, particle is in heaps, in particle in heaps oxygen supply not in place, affect particle burning efficiency, this ebullated bed biologyEach parts of matter particle boiler are extremely important.
Summary of the invention:
The purpose of this utility model is the function that fuel is dispersed in to abundant burning cracking in burner hearth in order to realize, and carriesFor a kind of ebullated bed biomass granule boiler Special rotary discharging elbow.
The utility model is to adopt following technical scheme to realize its goal of the invention: a kind of ebullated bed biomass granule boilerSpecial rotary discharging elbow, it is made up of the tubing that becomes angle of bend, and be provided with thereon rotating discharge bend pipe feeding channel 1,Rotating discharge bend pipe locating piece 2, wherein angle of bend is from the horizontal by inclination angle A3; Rotating discharge bend pipe locating piece 2 is located at curvedPipe bottom, the locating slot of adaptive miscellaneous part.
Owing to having adopted above technical scheme, the utility model has been realized its goal of the invention preferably, this ebullated bed biologyMatter particle boiler Special rotary discharging elbow can avoid occurring that distribution of particles is inhomogeneous, and particle is in heaps, in particle in heaps, suppliesOxygen is not in place, affects the situation of particle burning efficiency, makes uniform particles disperse to enter in boiler, and low oxygen combustion effect reaches a high temperatureMaking the abundant completing combustion of fuel, reach smokeless micronic dust effect, is the important composition parts of ebullated bed biomass granule boiler.

Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is cross-sectional view of the present utility model.
Description of reference numerals is shown in description last page form.
Detailed description of the invention:
Below in conjunction with accompanying drawing, summary of the invention is described further:
Embodiment 1:
From summary of the invention, a kind of ebullated bed biomass granule boiler Special rotary discharging elbow, it is by becoming angle of bendThe tubing of degree is made, and is provided with rotating discharge bend pipe feeding channel 1, rotating discharge bend pipe locating piece 2, wherein angle of bend thereonDegree is from the horizontal by inclination angle A3; Rotating discharge bend pipe locating piece 2 is located at bend pipe bottom, the locating slot of adaptive miscellaneous part.
Rotating discharge bend pipe feeding channel 1 described in the utility model refers to: rotating discharge bend pipe feeding channel; Its effectBe transfer the fuel, its design attitude is as shown in mark 1 in accompanying drawing 1,2.
Rotating discharge bend pipe locating piece 2 described in the utility model refers to: rotating discharge bend pipe locating piece; Its effect is to makeRotating discharge bend pipe and miscellaneous part are installed together, and restriction bend pipe skids off, and its design attitude is as shown in mark 2 in accompanying drawing 1,2.
Inclination angle A3 described in the utility model refers to: the inclination angle of rotating discharge bend pipe angle of bend and horizontal direction, it inclinesAngle schematic diagram is as shown in mark 3 in accompanying drawing 2.
