Abstract
The utility model relates to a three horizontal return stroke tobacco pipe formula biomass boiler. Including the burner hearth to and the overgrate air mother who sets up outside the burner hearth manages (1), the female pipe of overgrate air (1) through a plurality of rows of overgrate airs be in charge of introduce the burner hearth with the overgrate air in, adjacent row of overgrate air is in charge of and is certain angle dispersion setting. The utility model discloses carry out the optimal design to traditional overgrate air structure, change double (also can design to three rows or multirow according to the structure) never equidirectional introduction burner hearth into by single introduction burner hearth promptly, strengthen the disturbance of flue gas in aditus laryngis department, make it abundant burning and exothermic, lengthen the dwell time of fuel in the burner hearth effectively simultaneously, guarantee to fire the cinder, improve combustion efficiency, it is more ideal according to the in -service use operational effect.
Description
Technical field
The utility model relates to a kind of horizontal three return smoke tubular type biomass boilers, belongs to boiler technology field.
Background technology
Along with constantly improving and development of China's energy policy, biomass energy is as regenerative resource, and its industry obtains to be vigorously supported, and applies also more and more extensive.
In biomass boiler structure, secondary wind action is important.The reasonable of Secondary Air layout can ensure that fuel burns fully, and efficiency of combustion is high, and the emission smoke content of generation is low, SO2 and Knox content also reduces greatly, and effects of energy conservation and environmental protection is good; Current Secondary Air, due to the restriction of the various aspects such as structure, often adopts single row configuration, causes flue gas particle can not burning cmpletely, thus reduces efficiency of combustion, requires further improvement.
Utility model content
The utility model is for above-mentioned defect, and object is to provide one fully can ensure flue gas particle efficiency of combustion, reduces the horizontal three return smoke tubular type biomass boilers of one of environmental pollution.
The technical solution adopted in the utility model is for this reason: the utility model comprises burner hearth, and Secondary Air mother's pipe (1) be arranged on outside burner hearth, described Secondary Air mother's pipe (1) is in charge of by some row's Secondary Airs and is introduced in burner hearth by Secondary Air, and described adjacent row's Secondary Air is in charge of scattering device at an angle.
Further the utility model comprises two row's Secondary Airs and is in charge of, be designated as respectively Secondary Air be in charge of one (2) and Secondary Air be in charge of two (3), wherein Secondary Air is in charge of one (2) with horizontal direction is that 3-8 degree is arranged, Secondary Air is in charge of two (3) and is arranged on the bottom that Secondary Air is in charge of (2), and both angles are that 8-12 degree is arranged.
Described Secondary Air is in charge of one (2), Secondary Air is in charge of two (3) and is all tilted to lower setting.
Described Secondary Air is in charge of and is stretched in burner hearth from burner hearth aditus laryngis portion.
Described Secondary Air is in charge of one (2) and is 5 degree is tilted to lower setting with horizontal direction, Secondary Air be in charge of two (3) and Secondary Air be in charge of one (2) in 10 degree of settings.
Further the utility model comprise some Secondary Airs be in charge of one (2) and Secondary Air be in charge of two (3), Secondary Air be in charge of one (2) and Secondary Air be in charge of two (3) space crossings arrange.
The utility model has the advantages that: the utility model is optimized design to traditional Secondary Air structure, namely change double (also can be designed to three rows according to structure or arrange more) into by single introducing burner hearth and introduce burner hearth from different directions, the disturbance of flue gas is strengthened at aditus laryngis place, make it burning and heat release fully, effectively extend the time of staying of fuel in burner hearth simultaneously, guarantee to burn, improve efficiency of combustion; Use operational effect more satisfactory according to reality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Secondary Air structural representation of the present utility model.
Fig. 3 is the side view of Fig. 2.
1 be Secondary Air mother pipe in figure, 2 be in charge of two for Secondary Air is in charge of one, 3 for Secondary Air.
Detailed description of the invention
Below only for double Secondary Air structure (see photo), two combs are staggeredly arranged, the angle of upper comb and horizontal direction is 5 °, angle between two combs is 10 °, the benefit of such layout carries out twice disturbance to flue gas stream, and the disturbance formed again between twice disturbance between Secondary Air, the effective collision of flue gas particle can be accelerated, the time of staying of prolong smoke particle in stove, radiation and heat convection between strengthening further mutually simultaneously, more be conducive to burning of flue gas particle, guarantee efficiency of combustion.If the capacity of boiler is large, and Secondary Air arranges it is not difficulty especially, can consider that layout three to arrange or more Secondary Air, it to the disturbance of flue gas and effective prolong smoke at residing time in furnace advantageously, combustion efficiency is more obvious, and efficiency of combustion more can be guaranteed.
Contrast single Secondary Air structure, 10 tons of boilers prolong smoke time of suspending business to bring up to standard in stove can be about 1s, and efficiency of combustion can improve 0.5% ~ 1%, and more than 20 tons boilers prolong smoke time of suspending business to bring up to standard in stove can be about 2s, and efficiency of combustion can improve 1% ~ 2%; The successful of soot emissions simultaneously improves, CER about about 10%.
The utility model passes through and uses, the key data of design:
1, secondary air flow: account for 15% of total blast volume
2, secondary wind speed: 60-70m/s
3, the angle between Secondary Air: computer simulation aerodynamic field, all can be advisable by effective disturbance aditus laryngis flue gas with its jet.
Two, the actual effect run:
1, efficiency of combustion reaches more than 99%;
2, smoke discharge amount is almost nil;
3, SO
2and NO
xcontent is all at 80mg/m
3below.
