The utility model discloses can realize eliminating the influence of flue gas impurity to pipeline and valve from the clean ability of formula naked light nozzle pipeline oneself of discharging fume.
Description
Technical field
The utility model belongs to steel smelting equipment, is a kind of structure atomizer blowing pipeline device.
Background technology
The burner that steel mill's heat-treatment lines tempering stove adopts is from smoke exhausting type open flame combustion nozzle.Its smoke evacuation principle is the negative pressure draft being produced 1KPa by injection air at burner and smoke exhaust pipe place, and waste gas in stove is extracted out by burner smoke outlet by the negative pressure draft of additional smoke exhaust fan about 300 ~ 400KPa.
Such burner adopts pulse-combustion mode, and because magnetic valve is not a direct-open, the flue gas containing impurity after closed electromagnetic valve in stove pours in down a chimney along burner pipeline feed channel of making the return trip empty.Flue gas cools in the process of pouring in down a chimney, and part of smoke forms a large amount of impurity blocking injection air pipeline in the condensation of injecting tube place; Part of smoke forms impurity blocking comburent air duct at air line internal condensate.Finally cause burner medium pipeline Severe blockage and affect burner trouble-free burning.
Utility model content
The utility model aims to provide a kind of blowing pipeline device, can realize from smoke exhausting type open flame combustion nozzle pipeline self-cleaning, with the impact of impurity on pipeline and valve that remove smoke.
The purpose of this utility model is achieved through the following technical solutions:
Structure atomizer blowing pipeline device, comprises airline and smoke-exhaust pipeline, auxiliary scavenging pipeline and blow-off line.Described airline and smoke-exhaust pipeline refer to and combustion air arm are connected to burner body by burner pipe connecting, and are finally connected to smoke evacuation bleeder by magnetic valve connecting tee and smoke evacuation pipe connecting.Described auxiliary scavenging pipeline refers to perforate on compressed air line with burner pipe connecting and is connected it at tapping copper pipe one, and the fixing welding process of interface, copper pipe one is connected to ball valve one; Perforate on combustion air arm with threeway is also connected it at tapping copper pipe two, and the fixing welding process of interface, copper pipe two is connected to ball valve two.Described blow-off line refers to perforate on smoke evacuation pipe connecting, and at tapping connecting copper pipe three, the fixing welding process of interface, copper pipe three is connected to ball valve three.
The beneficial effect of utility model: can realize from smoke exhausting type open flame combustion nozzle pipeline self-cleaning ability, remove smoke the impact of impurity on pipeline and valve.
Accompanying drawing explanation
Accompanying drawing 1 is structure atomizer blowing pipeline apparatus structure schematic diagram.
In figure: 1-compressed air line, 2-copper pipe one, 3-ball valve one, 4-ball valve two, 5-copper pipe two, 6-burner pipe connecting, 7-threeway, 8-discharges fume pipe connecting, 9-ball valve three, 10-copper pipe three, 11-magnetic valve, 12-combustion air arm, and 13-discharges fume bleeder.
Embodiment
Below in conjunction with accompanying drawing 1 and embodiment, the utility model is described in further detail.
With reference to accompanying drawing 1, structure atomizer blowing pipeline device comprises airline and smoke-exhaust pipeline, auxiliary scavenging pipeline and blow-off line.Airline and smoke-exhaust pipeline refer to and combustion air arm (12) are connected to burner body by burner pipe connecting (6), and the magnetic valve (11) by carrying out opening and closing according to burner pulse signal, connecting tee (7) and smoke evacuation pipe connecting (8) are finally connected to smoke evacuation bleeder (13).Auxiliary scavenging pipeline refers to that row perforate is crept in electricity consumption on compressed air line (1), opening diameter 8mm, above electric drill perforate is used at burner pipe connecting (6), opening diameter 8mm, compressed air line (1) and burner pipe connecting (6) is connected at tapping copper pipe one (2), the fixing welding process of interface, on copper pipe one, (2) are connected to the ball valve one (3) for regulating pressure; In the upper perforate of combustion air arm (12), opening diameter 8mm, in the upper perforate of threeway (7), opening diameter 8mm, connect combustion air arm (12) and threeway (7) at tapping copper pipe two (5), the fixing welding process of interface, and pass through for pressure controlled ball valve two (4).Blow-off line refers in smoke evacuation pipe connecting (8) perforate, opening diameter 8mm, and at tapping connecting copper pipe three (10), the fixing welding process of interface, copper pipe three (10) is connected to for controlling the ball valve three (9) opened and closed.
Compressed air gas source pressure is 0.4 ~ 0.6Mpa.Combustion air arm (12) is connected burner body by magnetic valve (11) with burner pipe connecting (6), and is connected smoke evacuation bleeder (13) by threeway (7) with smoke evacuation pipe connecting (8), forms basic air and smoke-exhaust pipeline.By compressed air pipe (1) at burner Near Pipelines introducing pressurized air, connect compressed air pipe (1) with copper pipe one (2) and form auxiliary scavenging pipeline with burner pipe connecting (6), and regulated by ball valve one (3) realization purging pressure.By copper pipe two (5) short circuit magnetic valve (11), improve gas flow rates before and after magnetic valve (11), prevent impurity from condensing at magnetic valve (11) place.In smoke evacuation pipe connecting (11) bottom perforate, and connect with copper pipe three (10) and be made into sewage draining exit, carry out periodic blow down by the sewage of ball valve three (9) to condensation in pipeline.
