Abstract
The utility model discloses a burner fueled with chemical waste gas. The burner fueled with the chemical waste gas comprises an air channel, a Y-shaped hydrogen channel, an adjustable air channel, a first draught fan, a second draught fan, a hydrogen sufficient area, an air sufficient area and a cup-shaped flame stabilizing disc. The air channel, the Y-shaped hydrogen channel and the adjustable air channel are sequentially arranged at one end of a burner body from exterior to interior. The end portion of the adjustable air channel is connected with the cup-shaped flame stabilizing disc. The hydrogen sufficient area is arranged at the position of the cup-shaped flame stabilizing disc. The first draught fan and the second draught fan are correspondingly arranged at the A-A section of the burner body in the tangential direction. The air sufficient area is arranged at the other end of the burner body. Compared with the prior art, the burner fueled with the chemical waste gas has the advantages that the adjustable air channel is arranged, burning can be effectively controlled, and flame is effectively prevented from burning the burner out in a back flow process; and the draught fans are arranged at the end portion of a nozzle of the burner, disturbance can be increased, and hydrogen and air are fully mixed. According to the burner fueled with the chemical waste gas, a multi-path diffusive combustion mode and zoned-air distribution are adopted, and generation amount of the atmospheric pollutant NOx of the burner can be effectively reduced.
Description
Technical field
The utility model relates to burner, relates in particular to a kind of chemical emission burner that uses.
Background technology
Chlor-alkali industry can produce a large amount of byproducts in process of production, and its main component is a hydrogen, and a large amount of hydrogen is drained as waste gas substantially, has both wasted energy, and brings potential safety hazard again.Hydrogen is a kind of fuel gas of cleaning, be again a kind of high-risk gas aspect burning simultaneously, the combustion of hydrogen flame propagation speed is 8 times of combustion of natural gas speed, its concentration limit of catching fire (or claiming explosion limit) is the wideest in all fuel gas, reaches 4-75%.Hydrogen seldom as the fuel of boiler, therefore, use hydrogen on boiler, the design of burner is crucial, and burner need effectively solve the very easily tempering of generation in the combustion of hydrogen process, take off problems such as flame, detonation.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of chemical emission burner that uses is provided.
For achieving the above object, the technical solution adopted in the utility model is:
Use the chemical emission burner and comprise air duct, Y shape hydrogen passage, adjustable air passage, first blower fan, second blower fan, the sufficient district of hydrogen, the sufficient district of air, cup-shaped stable flame pan; Burner body one end is provided with gas passage, Y shape hydrogen passage, adjustable air passage from outside to inside in turn, adjustable air channel end and cup-shaped stable flame pan, cup-shaped stable flame pan place is provided with the sufficient district of hydrogen, the tangential correspondence of burner body A-A section is provided with first blower fan, second blower fan, and burner body is provided with the sufficient district of an end air in addition.
The beneficial effect that the utility model compared with prior art has is:
1, burner of the present utility model has an adjustable air passage, can prevent effectively that flame from burning out burner in reflux course, but the air capacity in the sufficient district of hydrogen make-up also makes hydrogen fully burn, and effectively control burning;
2, burner nozzle of the present utility model end is provided with blower fan, makes the cross section mist move along quadrangle tangential circle, can increase disturbance, makes hydrogen and air fully mix;
3, the utility model adopts the multiply diffusion combustion mode, i.e. combustion gas enters in the stove by a plurality of shower nozzle subregions, and combustion gas does not mix with air before burning, but gaseous fuel mixes with air on one side, and burn in one side, to prevent the tempering of waste gas burning process;
4, the utility model adopts zoned air, and forming flame kernel is the sufficient district of fuel, is the sufficient district of air around the flame, reduces the flame kernel ignition temperature, reduces flame propagation velocity, prevents tempering; Supply gas and zoned air by share split simultaneously, can reduce the growing amount of boiler atmosphere pollution NOx;
5, stable flame pan of the present utility model adopts special cup-like structure, make hydrogen near burner nozzle position forced refluence, form flame of centre, as ever-burning flame, when improving the fuel burn-off rate, effectively prevent to produce in the combustion process and take off flame, deflagration accident having;
6, burner of the present utility model load employing ratio is regulated, and compares with conventional gas burner simultaneously to have wideer adjusting ratio, to reduce the start-stop time of burner during the boiler operatiopn as far as possible.
Description of drawings
Fig. 1 uses chemical emission burner structure schematic diagram;
Fig. 2 is the flame flow cardon in the utility model A-A cross section;
Among the figure: air duct 1, Y shape hydrogen passage 2, adjustable air passage 3, first blower fan 4, second blower fan 5, the sufficient district 6 of hydrogen, the sufficient district 7 of air, cup-shaped stable flame pan 8.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in the figure, use the chemical emission burner and comprise air duct 1, Y shape hydrogen passage 2, adjustable air passage 3, first blower fan 4, second blower fan 5, the sufficient district 6 of hydrogen, the sufficient district 7 of air, cup-shaped stable flame pan 8; Burner body one end is provided with gas passage 1, Y shape hydrogen passage 2, adjustable air passage 3 from outside to inside in turn, adjustable air passage 3 ends and cup-shaped stable flame pan 8, cup-shaped stable flame pan 8 places are provided with the sufficient district 6 of hydrogen, the tangential correspondence of burner body A-A section is provided with first blower fan 4, second blower fan 5, and burner body is provided with the sufficient district 7 of an end air in addition.
Two parts are formed before and after the utility model, the first half burner is a cavity, cavity comprises sufficient district 6 of hydrogen and the sufficient district 7 of air, its spout end has 4 holes, link to each other with second blower fan 5 with first blower fan 4, the latter half burner is provided with cup-shaped stable flame pan 8 by being air duct 1 successively in outer the reaching in the middle of Y shape hydrogen passage 2 and the adjustable air passage 3, burner.
The course of work of the present utility model is as follows:
Air enters burner through air duct 1, flows directly into the burner latter half, has aperture on the cup-shaped stable flame pan 8, the part air can see through aperture and enter, hydrogen enters burner through Y shape hydrogen passage 2, flows directly into the burner latter half, and hydrogen and air burn while mixing, subregion is sent into, so form flame kernel is the sufficient district 6 of hydrogen, is the sufficient district 7 of air around the flame, reduces the flame kernel ignition temperature, reduce flame propagation velocity, prevent tempering.Cup-shaped stable flame pan 8 adopts special cup-like structure, makes hydrogen near burner nozzle position forced refluence, forms flame of centre, as ever-burning flame, when improving the fuel burn-off rate, effectively prevents to produce in the combustion process and takes off flame, deflagration accident having.Burner latter half end has aperture, under the effect of first blower fan 4 and second blower fan 5, the cross section mist is moved along quadrangle tangential circle, and can control air quantity by valve, as shown in Figure 2, thereby has strengthened disturbance, and it is more even that gas is mixed.Because combustion of hydrogen can produce in the sufficient district 6 of hydrogen and reflux, and for preventing that burner from being burnt out, adjustable air passage 3 is set, and by control valve, both can increase disturbance, the aftercombustion required air quantity can be protected burner again.
