Under the control of a computer, high temperature waste hydrogen and oil smoke which are generated in the furnace are returned to a heating mantle for combustion, thereby changing waste into valuable, not only increasing heat energy in the furnace, lowering the pollution level to the environment, but also reducing the use level of gas, and saving the production cost.
Description
Technical field:
The utility model relates to a kind of bell type annealing furnace, relates in particular to a kind of burner of perhydro combustion gas bell type annealing furnace.
Background technology:
In recent years; along with the sheet material of market to ferrous metal and non-ferrous metal bright annealing; the continuous increase of band demand; and these sheet materials; band is normal form transmission with rolling in production process; its heat 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 the process of annealing protects material; make it not oxidized; surface-brightening; and improved heat transfer efficiency; thereby improved anneal capability, also guaranteed temperature uniformity, guaranteed the mechanical property of coil of strip.And the hydrogen shield atmosphere of using, meeting other harmful substances such as emulsion remained oil smoke in coil of strip in heating process are discharged in the atmosphere, pollute to air ambient.Chinese invention patent application CN 1651583A discloses a kind of heater of perhydro strong convection bell type furnace, this device is made up of bell furnace housing, liquefied petroleum device burner assembly, liquefied gas pipeline and air pipe line by the portion of setting within it are lighted liquid gas oil gas, by being arranged on its outer instrument, instrument the gas in its pipeline is controlled then, made the temperature of burning reach required value.Compare with other heater, though have that flameholding is abundant, temperature-controlled precision is high, a compact conformation and can realize characteristics such as automation control, but can produce the useless hydrogen of high temperature, the emulsion that the while cold rolled strip coil brings, oxide are in annealing process, producing harmful substances such as oil smoke, steam, dust can all be discharged in the air with useless hydrogen, will pollute air ambient.
The utility model content:
The purpose of this utility model 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 got back in the heating mantles and to be burnt, it is turned waste into wealth.
The utility model is to realize like this, 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 that is fixed on the housing, it is characterized in that: on described housing, be fixed with hydrogen burner assembly, Hydrogen Line and air duct, described Hydrogen Line links to each other with described hydrogen burner assembly with air duct, and described Hydrogen Line is provided with a pair of pneumatic operated valve; On described air duct, be provided with valve.
The utility model 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 piping, guarantees the high temperature security of hydrogen in transmission course of giving up.

The specific 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 duct 1, described Hydrogen Line 2 links to each other with described hydrogen burner assembly 4 with air duct 1, and described Hydrogen Line 2 is provided with a pair of pneumatic operated valve 7; On described air duct 1, be provided with valve 15.
By magnetic valve A5 obstruct nitrogen pipeline 12 is installed between a pair of pneumatic operated valve 7, nitrogen gas pressure is generally 80-100mbar greater than the pressure of useless hydrogen.When faults such as power failure or pneumatic operated valve 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 electric control valve 9 on described Hydrogen Line 2, the effect by differential pressure orifice plate 8 makes the pressure of hydrogen reach setting value and just can open electric control valve 9, generally set value 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 pneumatic operated valve 7 and the orifice plate 8 before logical useless hydrogen.
A combustion fan 14 is arranged on described air duct 1, and the air that is used for fuel burner nozzle and hydrogen burner is supplied with.
In use, the UV sensor 10 that is subjected on the main burner assembly 4 when control system sends the signal that main burner has been lighted, open electric 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 electric control valve 9 and magnetic valve B6 then, close magnetic valve A5 again, open a pair of pneumatic operated valve 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 setting value, opens electric control valve 9, valve on the air duct 1, inject useless hydrogen and air, ignition then to hydrogen burner assembly 3 simultaneously.When not needing to burn, close the valve 15 on pneumatic operated valve 7, electric control valve 9, the air duct 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 pneumatic operated valve 7 leaks, play the effect that prevents that useless hydrogen from entering Hydrogen Line 2.
