Abstract
The utility model discloses a radiant tube damage automatic detecting and alarming device of an air protection metallurgical industrial furnace. The device solves the problem that quality of products is disqualified if radiant tube damage in a hearth is not easy to find timely in a working state of a burner and a radiant tube. The device is characterized in that the burner is composed of the radiant tube (2) and a burner body (3), wherein the portion of the radiant tube (2) extending into the hearth (1) is a double-layer inner hollow pipe, the back half portion is a single-layer sleeved pipe, a flange is arranged at the tail end of the radiant pipe (2), is sleeved on the burner body (3) and is fixed on an outer plate of the furnace wall, a combustion-supporting air duct (7) and a gas pipeline (6) are connected with corresponding air inlets of the burner body (3), and a low-pressure detecting and alarming device (4) is arranged on a smoke exhaust pipeline (5). The device has the advantages of being reasonable in structure, high in automation degree, small in labor intensity of workers, timely, accurate, high in production efficiency and the like. The device can be widely applied in the radiant tube of the air protection metallurgical industrial furnace.
Description
One, technical field
The utility model belongs to the damaged fast detecting equipment of metallurgical engineering technology combustion radiant tube, relates in particular to take the burning of radiant tube muffle, fuel to be transmitted in the burner hearth the damaged detection alarm device automatically of the gas shield metallurgical industry furnace radiating pipe that material heats, flue gas is in time got rid of in radiant tube by the radiation tube wall at the heat that the radiant tube internal combustion produces to forbidding aerobic in the burner hearth.
Two, background technology
The damaged detection of present domestic employing gas shield industrial furnace radiant tube do not have good way; when finding that the product oxide skin of burning till is excessive; mostly be with perusal and experience and go investigation; this method is not only backward in technique; and need the long investigation time; can not promptly and accurately find out damaged radiant tube, bring hidden danger to production safety, the quality that influences ordinary production and produce product.
Three, summary of the invention
The purpose of this utility model be convenient and swift, promptly and accurately find out damaged radiant tube, use that safety, labour intensity are low, operating efficiency and the high damaged detection alarm device automatically of radiant tube of automaticity.
The technical solution adopted in the utility model is: it comprises burner, gas pipeline, combustion-supporting airduct and smoke discharging pipe, burner is to be made of radiant tube and burner body, described radiant tube stretches into burner hearth inside and is divided into double-deck interior blank pipe, latter half is the individual layer sleeve pipe, its end arranges flange and is set in and is fixed in the furnace wall outside plate on the burner body, combustion-supporting airduct links to each other with the gas pipeline air inlet corresponding with burner body, be provided with low pressure detection alarm device at smoke discharging pipe, in smoke discharging pipe thereafter, be provided with the reducing orifice plate simultaneously.
The beneficial effects of the utility model: the detection alarm device is by detecting the variation of smoke discharging pipe internal pressure automatically, when detected pressure is lower than certain setting value, be low pressure, checkout gear sends alarm signal, remind operating personnel in time to close this brunched burner nozzle, and carry out the dismounting replacing of radiant tube, thus can control owing to the radiant tube breakage causes a large amount of oxygen to enter in the burner hearth for finding, influence product quality.This kind setting have degree height rational in infrastructure, automatic, labor strength little, promptly and accurately, the production efficiency advantages of higher, can be widely used in radiant tube gas shield industrial furnace.
The utility model is described in further detail below in conjunction with accompanying drawing.
Four, description of drawings
Fig. 1 is the utility model cross section structure schematic diagram.
Among the figure: 1 is burner hearth, and 2 is radiant tube, and 3 is burner body, and 4 is low pressure detection alarm device, and 5 is smoke discharging pipe, and 6 is gas pipeline, and 7 is combustion-supporting airduct, and 8 is the reducing orifice plate.
Five, the specific embodiment
Be example with the roller-bottom type gas shield industrial furnace of undertaking the construction of a long 22m * wide 1.1m * high 2.1m.It comprises furnace body system at the bottom of roller-bottom type input and output material system, the roller, radiant tube combustion exhaust gas system.In radiant tube combustion exhaust gas system, set up the damaged detection alarm device automatically of gas shield metallurgical industry furnace radiating pipe; it is by burner; gas pipeline 6; combustion-supporting airduct 7 and smoke discharging pipe 5 etc. are partly formed; burner is to be made of SiC radiant tube 2 and burner body 3; described SiC radiant tube 2 stretches into burner hearth 1 inside and is divided into double-deck interior blank pipe; latter half is the individual layer sleeve pipe; its end arranges flange and is set in and is fixed in the furnace wall outside plate on the burner body 3; combustion-supporting airduct 7 and gas pipeline 6 and burner body 3 corresponding air inlets link to each other; be provided with low pressure detection alarm device 4 at smoke discharging pipe 5, and in smoke discharging pipe 5 thereafter, be provided with reducing orifice plate 8.When implementing the utility model, combustion-supporting airduct 7 and gas pipeline 6 mix in burner body 3 and burn, the high-temperature flue gas that the burning back produces forms a round trip in SiC radiant tube 2, heat is conducted to burner hearth 1 by the radiation tube wall, flue gas after the heat exchange discharges out of the furnace by smoke discharging pipe 5, when the low pressure detection alarm device 4 realization SiC radiant tubes breakages that smoke discharging pipe 5 is installed, in time find, in order to improve the sensitivity of detection alarm device, at low pressure detection alarm device flue tube reducing orifice plate 8 is set, increases the flue gas pressures of this point.Pressure when low pressure detection alarm device 4 detects ordinary production in the smoke discharging pipe, show normal this moment, when 2 breakages of SiC radiant tube, flue gas enters into burner hearth 1 in the radiant tube 2, flue gas reduces in the smoke discharging pipe 5, and low pressure detection alarm device 4 is shown as low pressure at this moment, sends alarm signal, handled easily personnel in time find, in time handles.Both reduce the damaged investigation time of radiant tube, improved enterprise's production quantity, can also guarantee that product quality was greatly improved simultaneously, had application value widely.
