Description
Technical field
The utility model relates to a kind of detecting device of boiler furnace combustion flame, say further to relate to and a kind ofly utilize three photoelectric sensors that can receive different spectrum segments to receive the optical radiation signal in the certain spectral and convert electric signal to, thereby a kind of flame monitoring of judging the flame combustion chamber situation is with three spectrum segment Electro-Optic Sensor Systems.Belong to boiler furnace flame detection equipment technical field.
Background technology
The smooth combustion of fuel is depended in the safe operation of Industrial Boiler, kiln, and unsettled burning causes inefficient combustion and high pollution gaseous emission; Under extreme case, also can cause major accidents such as fray-out of flame, blast.Therefore, be safe operation, on the Industrial Boiler stability that flame detection equipment is indicated combustion flame must be installed.As everyone knows, the energy of combustion flame covers from ultraviolet, visible light to infrared one very wide continuous spectral coverage.At present, most of flame detectors all adopt low cost but reliably photoelectric sensor as sensitive element, and the photoelectric sensor that detects based on the optical radiation principle has been acknowledged as the most successful, this photoelectric sensor can convert the optical radiation signal in the certain spectral that receives to electric signal, through being used to judge the situation of flame after a series of processing.Exactly because and flame monitoring equipment is in the operating critical role of combustion completion, so whether whether the working condition of photoelectric sensor itself is a performance stable, have the detection of fault etc. also extremely important.Traditional flame detector only adopts single photoelectric sensor, thereby must judge the whether operate as normal of photoelectric sensor with an independent mechanical type self check mechanism, but this extra mechanical self check mechanism may also can become another factor that monitoring was lost efficacy.
Therefore, develop a kind of flame detector that not influenced by any self check hardware fault, the monitoring of boiler combustion flame is had crucial meaning with higher stability.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of optical sensitive unit is provided.This unit comprises three different photoelectric sensors, can judge combustion chambers burn flame situation, and the flame monitoring that does not need special-purpose mechanical type self check hardware is with three spectrum segment Electro-Optic Sensor Systems.
The technical solution of the utility model is achieved in that
A kind of flame monitoring is with three spectrum segment Electro-Optic Sensor Systems, comprise the photoelectric sensor shell, described photoelectric sensor shell connects the firing chamber by sighting tube, in the described photoelectric sensor shell Electrophotosensitive unit is set, described optical sensitive unit comprises the ultraviolet light photoelectric sensor, the visible light photoelectric sensor, infrared light photoelectric sensor and preposition translucent element, described ultraviolet light photoelectric sensor, visible light photoelectric sensor and infrared light photoelectric sensor receive combustion chambers burn flame radiation light signal by preposition translucent element, described ultraviolet light photoelectric sensor, the spectral response of visible light photoelectric sensor and infrared light photoelectric sensor is at ultraviolet light, visible light, can be overlapping in the infrared light spectrum scope, can be not overlapping yet.Because the signal of these three different photoelectric sensors has cross correlation, therefore, if one of them photoelectric sensor breaks down, not only can carry out localization of fault, and detecting device can utilize all the other two photoelectric sensor operate as normal, is repaired up to the photoelectric sensor that breaks down.In addition, the utility model is not subjected to any influence that adds mechanical self check hardware fault.
And the filtering amplification module is established in described ultraviolet light photoelectric sensor, visible light photoelectric sensor and infrared light photoelectric sensor back, signal gathering unit is established in described filtering amplification module back, signal processing unit is established in described signal gathering unit back, described ultraviolet light photoelectric sensor, visible light photoelectric sensor and infrared light photoelectric sensor will receive the radiant light conversion of signals by preposition translucent element and become electric signal, by being transferred to signal gathering unit after the filtering amplification, signal gathering unit is transferred to signal processing unit with this signal.
A kind of flame monitoring of the present utility model has following advantage with three spectrum segment Electro-Optic Sensor Systems with respect to prior art:
1, the utility model adopts three spectrum segment Electro-Optic Sensor Systems that flame is detected, and without any need for other mechanical self check hardware, thereby no longer is subjected to the influence of any mechanical self check hardware fault.The flame flicking signal that it utilizes three photoelectric sensors to obtain can carry out self check, differentiates the situation of extinguishing of flame and monitors flame holding.If a photoelectric sensor breaks down, not only can carry out localization of fault, and detecting device can utilize two remaining photoelectric sensor operate as normal, be repaired up to the photoelectric sensor that breaks down.
2, the utility model is simple in structure, and is cheap, and effect is obvious.
