Description
Technical field
The present invention relates to fuel apparatus technical field, particularly to the burner in this field, be specially a kind of biomass whirlwind dedusting burner.
Background technology
In recent years, the development and utilization of biomass energy is the most increasingly subject to people's attention, and is the most progressively promoted and applies.Biomass fuel is a kind of novel Environment-friendlyfuel fuel, has the features such as cleaning, high heating value, high combustion rate.Overwhelming majority biomass burner of the prior art is essentially identical with the combustion system of tradition coal furnace, or feed from above, or from following charging, no matter which kind of feed way, the most all there is the deficiency that burning is insufficient, efficiency of combustion is low, combustion fumes is big.
As the utility model of China Patent Publication No. CN201285034Y discloses a kind of biomass burner, this burner uses boiling type gasification, and combustion to add the design of tangent line spiral-flow type air distribution, combustion rate is up to more than 95%, biomass combustion is more complete, but unfortunately, fine dust during this burner combustion is easily followed thermal-flame and is flowed out together, and combustion fumes is big, and environment is also existed pollution.
And for example Authorization Notice No. is that the patent of invention of CN 102010755B discloses a kind of cyclone ash removal biomass burner, this burner uses feed pipe axial line and the combustor tangent design of cross section inwall, when wind is after feed pipe enters combustor, whirlwind can be formed at combustion chamber, utilize cyclonic separation principle to separate dust.This is designed with certain advance, it is disadvantageous that known in industry, cyclonic separation dust is typically limited to only low speed air intake air-flow, and when wind enters from feed pipe low speed, this burner has preferable dust removing effects.But justing think, in order to make burner combustion abundant, general air intake air velocity is the highest, and under high velocity air, cyclonic separation dust removing effects is the most preferable, and therefore, this invention also leaves some room for improvement in terms of practicality.
And for example Authorization Notice No. is that the utility model of CN 202229173U discloses a kind of vortex dust removing combustor, this burner for reaching dust removing effects, ad hoc centrifugal chamber, burn more abundant, dust removing effects is preferable, it may be said that be to solve the technical problem that burning is insufficient, combustion fumes is big.But owing to being additionally arranged centrifugal chamber and other associate member, whole burner volume is relatively big, constructs relative complex, and cost is the highest.
For another example Authorization Notice No. is the blowing gas combustion furnace that the utility model of CN201391875Y discloses a kind of built-in independent cyclone dust separator, it it is the combination of cleaner unit and burner, ash-laden gas dedusting is responsible for by cleaner unit, and dustless smoke combustion is responsible for by burner, and combination does not produce new function.
Summary of the invention
As mentioned above, biomass burner in existing industry more or less also exists certain technical deficiency, and the purpose of the present invention is through improving existing burner structure, thus provides a kind of structure relatively easy, the vortex burner that compact structure, good dedusting effect and combustion rate are high.
The present invention is achieved through the following technical solutions: this burner includes body of heater, for supporting the converter body support box of body of heater, the Automatic-feeding pipe that is arranged on body of heater, body of heater crater, body of heater door closure, innovation is: the top of body of heater, the lower end of body of heater crater arrange a cyclone dust removal burner, body of heater is separated into lower combustion chamber and top combustor by cyclone dust removal burner, and top combustor is provided with the secondary consistent with the cyclone dust removal burner hand of spiral for airduct.Wherein, cyclone dust removal burner is by matrix cylinder and is arranged on S type helical blade matrix cylinder outside and forms, and described S type helical-blade head, tail end are spaced and connect, and S type helical blade helical angle is 15 ° ~ 30 °.
Further, described S type helical blade quantity is 6 ~ 10, and as a kind of decision design, when S type helical blade quantity is 8, dedusting and combustion efficiency are optimal.
Further, the diameter of described body of heater crater is less than the diameter of described matrix cylinder, and body of heater crater bottom arranges convex edge, and convex edge is at a distance of cyclone dust removal burner upper surface, or matrix cylinder upper surface 20-40mm, contribute to preferable effect retains dust granule.
Further, described S type helical blade contacts with inboard wall of furnace body, lower combustion chamber burning after formed flame can only between S type helical blade spiral to top combustor, after cyclone dust removal burner, flame formation spiral flame, simultaneously under the secondary auxiliary for airduct, form adhesion combustion at upper of furnace body combustor, improve combustion rate.
Further, described secondary flushes with described S type helical blade top for airduct mouth of pipe lower wall.
Further, described cyclone dust removal burner centre axis and described body of heater central axes.
Further, as a kind of preferred version, at described matrix cylinder central axis, class arranges a through hole, and on through hole, the equipped round closure plate consistent with hole size, is used for collecting dust granule.After dust granule is collected to a certain degree, take off round closure plate and can clean out dust granule easily, it is not necessary to entirety takes off cyclone dust removal burner to clear up dust.
Compared with prior art, the present invention has the beneficial effects that:
1, cyclone dust removal burner it is additionally arranged, by cyclone dust removal structure parameters of burner optimization is designed, the rear flame making lower combustion chamber forms spiral flame at top combustor, simultaneously under the secondary auxiliary for airduct, secondary adhesion combustion is formed at upper of furnace body combustor, substantially increasing the combustion rate of biomass, combustion rate can reach 97%, higher than the combustion rate of like product in prior art 95%.
2, at cyclone dust removal burner centre axis, a matrix cylinder is devised, the diameter of matrix cylinder is more than body of heater crater diameter, simultaneously, body of heater crater convex edge is deep into furnace interior, at a distance of matrix cylinder top 20 ~ 40mm, so, the dust granule formed after burning further enhances the effect of the poly-dirt of attached wall under the action of the centrifugal at top combustor, the combustion efficiency of burner, dust removal performance and stove fire purity are significantly improved, smoke dust discharge concentration≤5/m3, flue gas blackness reaches Ringelman 0 grade, will not overflow more than 30 microns of dusts, substantially can reach the effect of smokeless and dust free, higher than like product in prior art.
