A computer is adopted for automatic control, and high-temperature waste hydrogen and oil fume generated in the furnace are returned to a heating mantle for combustion, so as to change the waste into the valuable, thereby not only adding heat energy into the furnace and reducing the environmental pollution but also reducing the fuel gas consumption and saving the production cost.
Description
Technical field: the present invention relates to a kind of perhydro combustion gas bell type annealing furnace, relate in particular to the combustion unit of the useless hydrogen of a kind of perhydro combustion gas bell type annealing furnace.
Background technology: in recent years; along with the continuous increase of market to high-quality sheet material, band demand; and these sheet materials, band in production process often with the form transmission of rolling; its thermal treatment mainly relies on bell type annealing furnace for a long time; present state-of-the-art technology is to adopt the perhydro strong convection bell type furnace to handle; needing to feed hydrogen in carrying out the annealed process protects material; make it not oxidized; surface-brightening; and improved heat transfer efficiency; thereby the raising anneal capability has also been guaranteed temperature uniformity, has guaranteed the mechanical property of coil of strip.And the hydrogen shield atmosphere of using, other objectionable impuritiess such as emulsion remained, greasy dirt that can be in coil of strip in heat-processed are discharged in the atmosphere, pollute to air ambient.Chinese invention patent application CN1651583A discloses a kind of heating unit of perhydro strong convection bell type furnace; this device is made up of bell furnace housing, fuel burner nozzle control assembly, liquefied petroleum device burner assembly; gas line and airline by the portion of setting within it are lighted combustion gas; carry out interlock protection by computer control system, temperature control system then; guarantee the quality of materials after annealing temperature, annealing time, the annealing, reach satisfied effect.Compare with other heating unit, have that flameholding is abundant, temperature-controlled precision is high, characteristics such as compact construction and automatic controlling level height, but the useless hydrogen of the high temperature that produces, and objectionable impurities such as emulsion of bringing of cold-reduced sheet, oil smoke that greasy dirt produces in annealing process, water vapour, impurity can all be discharged in the air with useless hydrogen, will pollute air ambient.
Summary of the invention: purpose of the present invention has overcome deficiency of the prior art exactly; provide a kind of perhydro combustion gas used for hood-type annealing furnace novel useless hydrogen burning device; because of hydrogen is a kind of inflammable and explosive hazardous gas; this device is under automatic control mode; by a series of security interlocking protection measure the useless hydrogen that produces in the stove and oil smoke are turned back in the heating mantles again and to burn, it is turned waste into wealth.
The present invention realizes like this, a kind of full-hydrogen hood-type annealing furnace is with novel useless hydrogen burning device, comprise the fuel burner nozzle assembly that is fixed on the housing, it is characterized in that: on described housing, be fixed with hydrogen burner assembly, Hydrogen Line and air line, described Hydrogen Line links to each other with described hydrogen burner assembly with air line, and described Hydrogen Line is provided with a pair of pneumavalve; On described air line, be provided with regulated valve.
The present invention compared with prior art has following advantage:
1. because useless hydrogen of high temperature that will generate in the stove and oil smoke are got back in the heating mantles burns, it is turned waste into wealth, both gives to increase heat energy in the stove, reduce pollution environment, reduced again combustion gas consumption, save production cost.
2. take computer controlled automatic, under manual mode, can not open the hydrogen burner, guarantee that simultaneously the hydrogen burner just can be lighted when main burner combustion, guarantee the combustion completion of useless hydrogen.
3. adopt before the burner combustion nitrogen to purge, guaranteeing does not have air in the exhaust pipeline, guarantees the high temperature security of hydrogen in transmission course of giving up.

Hydrogen Lines 3. hydrogen burner assemblies 4. fuel burner nozzle assemblies 5. magnetic valve A6. magnetic valve B 7. pneumavalves 8. differential pressure orifice plates 9. motor-driven control valve 10.UV transmitters 11. housings 12. intercept nitrogen pipeline 13. and purge nitrogen pipeline 14. burner blowers 15. valves
Embodiment: as can be seen from Figure 1, the novel useless hydrogen burning device of a kind of perhydro combustion gas used for hood-type annealing furnace, comprise the fuel burner nozzle assembly 4 that is fixed on the housing 11, it is characterized in that: on described housing 11, be fixed with hydrogen burner assembly 3, Hydrogen Line 2 and air line 1, described Hydrogen Line 2 links to each other with described hydrogen burner assembly 3 with air line 1, and described Hydrogen Line 2 is provided with a pair of pneumavalve 7; On described air line 1, be provided with regulated valve 15.
By magnetic valve A5 obstruct nitrogen pipeline 12 is installed between a pair of pneumavalve 7, nitrogen gas pressure is generally 80-100mbar greater than the pressure of useless hydrogen.When faults such as power failure or pneumavalve 7 appearance leakages, magnetic valve (5) will be opened automatically, enter the nitrogen higher than useless gas pressure, cut off entering of useless hydrogen, and the accident that prevents takes place, and plays the safeguard protection effect.
Also be provided with differential pressure orifice plate 8 and motor-driven control valve 9 on described Hydrogen Line 2, the effect by differential pressure orifice plate 8 makes the pressure of hydrogen reach set(ting)value just can open motor-driven control valve 9, and general set(ting)value is in the scope of 12.5-50mbar.
In order to guarantee that Hydrogen Line 2 does not have air to exist, and is provided with purging nitrogen pipeline 13 by magnetic valve B6 on the Hydrogen Line 2 between described pneumavalve 7 and the orifice plate 8 before logical useless hydrogen.
A burner blower 14 is arranged on described air line 1, and the air that is used for fuel burner nozzle and hydrogen burner is supplied with.
In use, the UV transmitter 10 that is subjected on the main burner assembly 4 when Controlling System sends the signal that main burner has been lighted, open motor-driven control valve 9 and magnetic valve B6, from purging nitrogen pipeline 13 to Hydrogen Line 2 nitrogen injections, guaranteeing does not have air in the Hydrogen Line 2, close motor-driven control valve 9 and magnetic valve B6 then, close magnetic valve A5 again, open a pair of pneumavalve 7, in Hydrogen Line 2, inject useless hydrogen, useless hydrogen constantly increases by the operational pressure of differential pressure orifice plate 8, when its pressure reaches set(ting)value, opens motor-driven control valve 9, valve on the air line 1, inject useless hydrogen and air, ignition then to hydrogen burner assembly 3 simultaneously.When not needing to burn, close the valve 15 on pneumavalve 7, motor-driven control valve 9, the air line 1, open magnetic valve A5 then from intercepting nitrogen pipeline 12 nitrogen injections, because nitrogen gas pressure is greater than the pressure of useless hydrogen, in case pneumavalve 7 leaks, play the effect that prevents that useless hydrogen from entering Hydrogen Line 2.
