Technical field
The utility model relates to a kind of biogas burner, is specifically related to a kind of spiral-flow type biogas burner.
Background technology
After the percolate station of present garbage incinerating power plant and Treatment of Sludge, a large amount of biogas is produced in reaction, and the main component of biogas is methane.Biogas is by 50% ~ 80% methane (CH4), 20% ~ 40% carbon dioxide (CO2), 0% ~ 5% nitrogen (N2), the hydrogen (H2) being less than 1%, the gas composition such as oxygen (O2) and 0.1% ~ 3% hydrogen sulfide (H2S) that is less than 0.4%.Because biogas contains a small amount of hydrogen sulfide, so slightly stink.Its characteristic is similar to natural gas.Density is 0.717kg/m
3, atmospheric density is 1.29kg/m
3, the main component methane of biogas is a kind of desirable gaseous fuel, namely can burn after mixing with appropriate air.The caloric value of every cubic metre of pure methane is 34000 kilojoules, and the caloric value of every cubic metre of biogas is about 20800-23600 kilojoule.Namely, after 1 cubic metre of biogas burns completely, the heat being equivalent to 0.7 kilogram of anthracite and providing can be produced; Compared with other combustion gas, its capability of antidetonance is better, is a kind of well clean fuel.The main processing ways of this part biogas is incorporated in incinerator by the biogas system of melting down to burn now, plays the effect of auxiliary combustion, increases the heat of combustion furnace; But how allowing biogas combustion better, the efficiency improving biogas combustion is the problem that we study, and the utility model will a kind of burner with swirl vane of research.
Utility model content
The utility model mainly provides a kind of spiral-flow type biogas burner that a kind of efficiency of combustion is high, be with swirl vane.
A kind of spiral-flow type biogas burner comprises burning torch, oxygen supply wind machine, oxygen supply wind import, biogas import, biogas combustion mouth, swirl vane, igniter solenoid valve; Described burning torch is connected with ignition coil, and biogas lighted by igniter solenoid valve control point firelock; Described oxygen supply wind machine sends combustion air to air distribution housing by oxygen supply wind import; Described swirl vane is arranged in air distribution housing, is provided with ion bar flame detector above biogas combustion mouth; Below biogas combustion mouth, ultraviolet flame detectors is installed; Described swirl vane is the tangential vane of spiral-flow type rule, is provided with oxygen supply wind pressure switch above oxygen supply wind machine.
Biogas enters from biogas import, enter in air distribution housing along biogas pipeline, oxygen supply wind oxygen supply wind machine drive under enter in air distribution housing from oxygen supply wind import, when biogas and oxygen supply wind are by swirl vane, rotate, after the injection of biogas pipeline spout, form rotating jet, utilize rotating jet to be formed and be beneficial to the high temperature gases recirculating district caught fire, and air-flow is mixed strongly; Open igniter solenoid valve, under the effect of ignition coil, burning torch is lighted a fire, and biogas is lighted; Biogas and oxygen supply wind, after swirl vane eddy flow penetrates, are formed centrally interior recirculating zone in the gas flow; The interior recirculating zone high-temperature flue gas entrainmented in port carrys out heating biogas air-flow, and marsh gas flow has certain heat and initial burning after reaching ignition temperature, and flame is outwards propagated from the inward flange of interior recirculating zone; Meanwhile, form exteenal reflux district in the periphery of swirling eddy, exteenal reflux district entrainments high-temperature flue gas and comes heating biogas and combustion air.
The swirling eddy mixing ratio that interior recirculating zone and exteenal reflux district are formed is stronger, and biogas and oxygen supply wind are fully mixed, and combustion process is carried out continuously, and ratio of combustion is comparatively abundant, and efficiency of combustion is improved; The swirling eddy that swirl vane is formed is compared with direct projection air-flow, and swirling eddy more can make biogas and oxygen supply wind mixing, makes burning more abundant; Use vortex burner that biogas combustion can be made complete, efficiency of combustion more than 99.5%, energy-conservation more than 5%, flue gas injection speed is high, noise is little, not tempering, de-fire; Overcome the flame instability because causing containing tar, impurity, liquid hydrocarbon in combustion gas, coking, clogging.
The utility model adopts swirl vane to form interior recirculating zone and exteenal reflux district, biogas and oxygen supply wind is fully mixed, improves efficiency of combustion, saved the energy.
