Description
Technical field
The utility model relates to a kind of industrial furnace, especially relates to a kind of industrial furnace with automatic ignition device.
Background technology
Many industrial furnaces can produce band imflammable gas and pernicious gas in process of production, if these gases directly are discharged in the atmosphere, not only can also can bring hidden danger by contaminated air, can produce carbon monoxide such as the nicarbing stove, the waste gas such as nitrogenous ammonia, because gas generated little, be difficult to collection and treatment, usually the method that all adopts the direct-fire burning to remove a hidden danger, method to waste gas produced igniting is also had nothing in common with each other, mainly can be divided into manual firing and automatic ignition dual mode, but the manual firing is dangerous large, and the possibility of realization is little, need to take automatic ignition to the emission gases igniting of industrial furnace institute.Chinese patent literature discloses the patent of " a kind of electric igniter of industrial furnace ", its Granted publication number is CN 201779692 U, Granted publication day is on March 30th, 2011, summary of the invention is, be provided with burning torch, Circuits System, small handcart, LPG cyoinders, burning torch is mainly by stable flame cover, gas spray head, outer tube, handle, the sparking electrode, the parts such as air inlet pipe form, LPG cyoinders links to each other with air inlet pipe with magnetic valve provided thereon by the source of the gas line, Circuits System is provided with battery pack, the time relay, step-up transformer, self-lock switch and cable etc., step-up transformer is located in the handle, self-lock switch is located on the handle, magnetic valve, battery pack and the time relay are located in the electric control box, and electric control box and LPG cyoinders all are located on the small handcart.What above-mentioned patent scheme adopted is exactly manual firing's mode, be applicable to safer environment, igniting such as petroleum refining and petroleum chemical industry tubular heater, also can be used for the igniting of various coal-fired industry furnaces, but for the not clear environment of atmosphere, manual firing's danger is too large, should not adopt.
The utility model content
The utility model is in order to overcome the safe not problem of industrial furnace discharging waste gas sparking mode of prior art, to provide a kind of safe and reliable, the industrial furnace with automatic ignition device simple for structure.
To achieve these goals, the utility model is by the following technical solutions: with the industrial furnace of automatic ignition device, comprise the industrial furnace exhaust apparatus, also comprise automatic ignition device, described automatic ignition device is provided with power supply, the time relay, potential device, igniter, described power supply is communicated with potential device by the time relay, and described igniter is communicated with potential device, and described igniter is located in the industrial furnace exhaust apparatus.Industrial furnace all is provided with exhaust emission device, the words that exhausted air quantity is large also can focus on through special gas sampling treating apparatus, and the little industrial furnace of some waste gas discharge capacities, be difficult to carry out identical processing, can adopt special igniter that the gas igniting of these a small amount of dischargings is burned, remove a hidden danger and pollute, igniter adopts the electronic ignition device of automatic ignition, can avoid the manual firing to face the danger of not clear atmosphere, power supply accesses potential device by the time relay, access again electronic ignition device after the current boost of potential device with input, igniter produces electric spark under the high-tension current effect, the waste gas that the industrial furnace that ignites produces is cut off the electricity supply after waste gas burning is complete, stops igniting.
As preferably, described power supply is dc source.The direct current step-up method is more, is convenient to flexible use.
As preferably, described potential device is provided with oscillator, booster circuit, rectification circuit.Oscillator is connected with power supply by the time relay, be used for the DC voltage of input is carried out the higher-order of oscillation and exports electronics harmonic oscillation voltage, booster circuit is connected with oscillator, be used for the electronics harmonic oscillation voltage of oscillator output is boosted, rectification circuit is connected with oscillator with booster circuit, can be used for rectification and produce dc high voltage, and low-voltage is returned to oscillator re-start the higher-order of oscillation.
As preferably, described igniter is ceramic rotor.Adopt ceramic rotor, cause electric pole short circuit in the time of can avoiding ignitor two interpolars to produce the medium such as iron filings, and ceramic material is high temperature resistant, corrosion-resistant, can increase the service life.
Therefore, the utlity model has following beneficial effect: (1) has avoided manually-operated, and is safe and reliable; (2) simple in structure, convenient durable.
Description of drawings
Fig. 1 is a kind of circuit diagram of the present utility model.
Fig. 2 is a kind of structural representation of the utility model potential device.
Among the figure: 1, industrial furnace exhaust apparatus 2, power supply 3, the time relay 4, potential device
5, igniter.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Among the embodiment as shown in Figure 1 and Figure 2, industrial furnace with automatic ignition device, comprise industrial furnace exhaust apparatus 1, also comprise automatic ignition device, described automatic ignition device is provided with power supply 2, the time relay 3, potential device 4, igniter 5, and power supply 2 is communicated with potential device 4 by the time relay 3, and potential device 4 is provided with oscillator, booster circuit, rectification circuit, igniter 5 is communicated with potential device 4, and igniter 5 is ceramic rotor and is located in the industrial furnace exhaust apparatus 1.
Specific implementation process is, when industrial furnace passes through industrial furnace exhaust apparatus 1 discharging waste gas, power supply 2 is by the time relay 3 access potential devices 4, the DC voltage of a pair of oscillators input carries out the higher-order of oscillation and exports electronics harmonic oscillation voltage to booster circuit, booster circuit is to the electronics harmonic oscillation voltage of the oscillator output rear input rectification circuit that boosts, the dc high voltage input igniter 5 that the rectification circuit rectification produces, and low-voltage is returned to oscillator re-start the higher-order of oscillation, igniter 5 produces electric spark under the high-tension current effect, the waste gas that the industrial furnace that ignites produces, cut off the electricity supply 2 after waste gas burning is complete, stop igniting.
