Abstract
The utility model relates to a novel coal-burning vertical smoke-eliminating and dust-controlling device for a boiler, which is composed of a blower interface, a once air pipe, a flabellate outlet, a once air conditioning valve, a quadric air pipe, a quadric air conditioning valve, an air passage stop plate, a quadric air annular pipe and a duckbill spray pipe. An air feed annular pipe is fixed on the external wall of the boiler, and the wall of the boiler is provided with a plurality of symmetrical holes. The wind in the air feed annular pipe is sent into the boiler chamber by the duckbill spray pipe to make combustible matters of carbon monoxide, hydrogen methane, carbon granule, etc., which are in the combustible solid fuel of the coal and are not burnt out, combusted sufficiently and the utility model not only improves heat efficiency, but also obtains smoke-eliminating and dust-controlling purpose. The device is adapted for modification of smoke-eliminating and dust-controlling of an existing ancient coal-fired vertical normal-pressure boilers or bearing-pressure boilers of various models and different specifications.
Description
Technical field
The utility model relates to a kind of novel coal vertical boiler device for eliminating smoke and dust.
Background technology
Coal-fired vertical boiler commonly used does not at present mostly install any device for eliminating smoke and dust additional, makes pernicious gas directly enter atmosphere, has caused great environmental pollution.The facture of intercepting of passive type is mostly adopted in general boiler smoke abatement dedusting, as water film dedusting, electrostatic precipitation, granite water film dust, cyclone dust removal, bag-type dust and multi-tube dusting etc.Though these cleaners can reach certain treatment effect, the some shortcomings part is also arranged, big as volume, the operating cost height produces secondary pollution, and cost height and smoke medicining dust-removing effect are undesirable, and ature of coal is had relatively high expectations, and fireman's labour intensity is big etc.For addressing this problem, Chinese patent 2004200511526 welds air feed air loop duct and secondary air feed air loop duct respectively on the wall of the upper and lower internal bladder cavity of boiler furnace fire grate, by the treatment technology of the rationally quantitative air feed in burner hearth internal combustion district, reached the purpose of smoke elimination depositing dust.The structure of this boiler can't be suitable for existing old-fashioned boiler.The utility model has redesigned a kind of existing old-fashioned coal-fired vertical boiler device for eliminating smoke and dust that is suitable on the basis of Chinese patent 2004200511526.
Summary of the invention
The utility model purpose is that the novel coal vertical boiler device for eliminating smoke and dust of design is made up of fan interface, airduct, fan-shaped outlet, primary air flow control valve, secondary air channel, secondary air flow control valve, air channel blind plate, secondary wind ring pipe and a duckmounth jet nozzles; The air feed ring pipe is fixed on the outer wall of boiler, and on the boiler wall, have several symmetrical holes, by duckmounth jet nozzles the wind in the air feed ring pipe is entered in the burner hearth, combustibles such as the carbon monoxide that do not have after-flame in the coal in the flammable solid fuel, hydrogen methane, carbon granules are fully burned, promptly improve the thermal efficiency, reached the purpose of smoke elimination depositing dust again.This device is applicable to the vertical normal-pressure boiler of existing old-fashioned fire coal of various models and different size or the transformation of bearing boiler smoke abatement and dust control.
Novel coal vertical boiler device for eliminating smoke and dust described in the utility model, this device is made up of fan interface, airduct, fan-shaped outlet, primary air flow control valve, secondary air channel, secondary air flow control valve, air channel blind plate, secondary wind ring pipe and a duckmounth jet nozzles; Be welded with secondary wind ring pipe (10) in the Boiler door both sides along boiler casing, the two ends of secondary wind ring pipe (10) are welded with air channel blind plate (3) respectively; By having fixedly duckmounth jet nozzles (2) of several symmetrical holes on boiler casing (12) and the inner bag (11), an end of duckmounth jet nozzles (2) is communicated with welding with secondary wind ring pipe (10), and its other end is communicated with welding with burner hearth (13) inner bag; Fan interface (7) locates to be connected with a secondary wind air main (9) and an airduct (5), the other end of secondary wind air main (9) is connected with a side bottom hole of secondary wind ring pipe (10), and in secondary wind air main (9), be provided with secondary air flow control valve (8), the other end of an airduct (5) is connected with the fan-shaped air outlet (4) that is fixed on fire grate (1) bottom by the hole on the furnace wall, fan-shaped air outlet (4) is aimed at tangential the going up with outer courage inwall in fire grate middle part and is formed acute angle, is provided with primary air flow control valve (6) in an airduct (5).

The specific embodiment
Further describe and provide embodiment below in conjunction with accompanying drawing
Novel coal vertical boiler device for eliminating smoke and dust described in the utility model, this device is made up of fan interface, airduct, fan-shaped outlet, primary air flow control valve, secondary air channel, secondary air flow control valve, air channel blind plate, secondary wind ring pipe and a duckmounth jet nozzles; Be welded with secondary wind ring pipe (10) in the Boiler door both sides along boiler casing, the two ends of secondary wind ring pipe (10) are welded with air channel blind plate (3) respectively; By having fixedly duckmounth jet nozzles (2) of several symmetrical holes on boiler casing (12) and the inner bag (11), an end of duckmounth jet nozzles (2) is communicated with welding with secondary wind ring pipe (10), and its other end is communicated with welding with burner hearth (13); Fan interface (7) locates to be connected with a secondary wind air main (9) and an airduct (5), the other end of secondary wind air main (9) is connected with a side bottom hole of secondary wind ring pipe (10), and in secondary wind air main (9), be provided with secondary air flow control valve (8), the other end of an airduct (5) is connected with the fan-shaped air outlet (4) that is fixed on fire grate (1) bottom by the hole on the furnace wall, fan-shaped air outlet (4) is aimed at tangential the going up with outer courage inwall in fire grate middle part and is formed acute angle, is provided with primary air flow control valve (6) in an airduct (5).
In use, enter an airduct (5) and secondary wind air main (9) and secondary wind ring pipe (10) by the air blast air-supply through air blast interface (7), open control valve (6), (8) regulation and control air quantity, the fan-shaped air outlet (4) that the wind of sending into enters boiler bottom through an airduct (5) passes fire grate and enters coal-fired layer; Secondary wind enters the combustion chamber through secondary wind ring pipe (10) by duckmounth jet nozzles (2); Because duckmounth jet nozzles (a 2) left side is high right low, symmetric arrays, make the flue gas in the combustion chamber form vortex, prolonged the flow process of flue gas, rely on the centrifugation of vortex, unburnt carbon granules is got rid of the resume combustion of tempering bed, thereby reduced unburned carbon in flue dust, reduce the imperfect combustion heat loss of solid, and improved the thermal efficiency.This device is through rationally quantitative air feed treatment technology, and soot emissions have reached national environmental standard.
