Abstract

The utility model relates to a cyclone circulating burner, which is characterized in that an inner hull is arranged in a housing and the left side of the housing is successively provided with a time air inlet duct, a secondary cyclone inlet duct, a cubic air inlet duct, and a quartic air inlet duct; the inner hull is also correspondingly provided with the a secondary air supply port, a cubic air supply port, and a quartic air supply port and the right side of the inner hull is provided with a secondary air-collecting duct, a cubic air-collecting duct, and a quartic air-collecting duct; the upper part of the housing is provided with a chimney and the lower right side is provided with a return gap. The utility model has the advantages: the utility model can be used independently or as a contributing structure of a boiler or heat equipment; the coal is burned fully on the grate bar through four times of air inlet so that smoke and dust discharge reduces to improve environmental pollution.

Description

The eddy flow cyclic burner

Technical field

The utility model relates to a kind of eddy flow cyclic burner, and it is the thermal cycle system of boiler plant, also is the servicing unit of other firing equipment, belongs to the technical field of burner.

Background technology

The combustion equipment of existing boiler combustion system or other equipment all is first and second air intake, in combustion process,, coal can not be fully burned, both influence its thermal efficiency unburnt coal is discharged together in company with waste gas because the coal seam is thicker, also polluted environment simultaneously, demanded urgently improving.

Summary of the invention

The purpose of this utility model is that a kind of eddy flow cyclic burner will be provided, and it can also can be equipped with other Thermal Equipment as the combustion chamber of boiler plant.It can make coal be fully burned, and reduces unburnt fixed carbon, improves the thermal efficiency, but also reduces the discharge of flue dust, improves environmental situation.

The structure of eddy flow cyclic burner is that an inner bag (17) is arranged in the casing (16), casing (16) left side is equipped with four wind blast pipes (5), three whirlwind blast pipes (4) and secondary air intake pipe (3) successively, and this blast pipe is stretched into inner bag (17) by body of heater outside water level land and joins.Four hot blast air outlets (18), tertiary air air outlet (7) and secondary wind air outlet (9) should be arranged in the inner bag (17) mutually, and inner bag (17) right side has four wind collectors (6), tertiary air collector (8) and secondary wind collector (10) successively.Return pipe (11) is equipped with in casing (16) lower right side.The lower-left side of casing (16) is equipped with primary air intake pipe (1), and chimney (15) is equipped with at casing (16) top, and atmosphere row port (14) is equipped with at the left top of casing (16), and fire grate (2) is contained in the bottom of inner bag (17).

The advantage of eddy flow cyclic burner is to have four wind air outlets and a blast pipe, coal is fully burned and reduces the discharge of flue dust through four air intakes, has improved environmental situation.

Description of drawings

Fig. 1. eddy flow cyclic burner schematic diagram

By Fig. 1, an inner bag (17) is arranged in the casing (16), casing (16) left side is equipped with four wind blast pipes (5), three whirlwind blast pipes (4) and four wind blast pipes (3) successively, and this blast pipe is stretched into inner bag (17) by body of heater outside water level land and joins.Four hot blast air outlets (18), tertiary air air outlet (7) and secondary wind air outlet (9) should be arranged in the inner bag (17) mutually, and inner bag (17) right side has four wind collectors (6), tertiary air collector (8) and secondary wind collector (10) successively.Return pipe (11) is equipped with in casing (16) lower right side, the bottom of casing (16) and inner bag (17) joins with the circle (12) of getting a foothold, the bottom of casing connects a lower margin circle (13), its can support machine casing (16) in ground, the lower-left side of casing (16) is equipped with primary air intake pipe (1), chimney (15) is equipped with at casing (16) top, and atmosphere row port (14) is equipped with at the left top of casing (16), and fire grate (2) is contained in the bottom of inner bag (17).

The specific embodiment

Coal places above the fire grate (2), in the combustion chamber of forming jointly by a wind air inlet (1), secondary wind air inlet (3), tertiary air air outlet (4) and four hot blast ajutages (5), because wind and secondary wind action produce a large amount of coal gas, high speed rotary combustion and flue gas is risen under the effect of three whirlwind again, last under the effect of four hot blasts, make the flue gas burning of circling round from top to down, form the high speed rotary combustion body of a solid and discharge a large amount of heats, its flue gas discharges from chimney (15).

This burner makes burning that the transformation of solid phase and gas phase take place rapidly owing to adopt the structure of four air intakes.When blowing for the second time, make coal in the high temperature of burning, constantly produce CO, this just forms the coal gas generating region and increased in the flue gas group the unburnt fixed carbon required oxygen that burns away when blowing for the third time, and formed centrifugal component from bottom to top, mixed hot-air and the fixed carbon that fully burnt consumingly, form the circulating combustion body of the mixing rotation of a level solid when the 4th air-supply, this is called the swirl flow combustion district.By above-mentioned action, make combustible totally burned, therefore reach the function of eliminating flue dust.
