Description
(1) technical field
The utility model relates to a kind of flame monitoring apparatus, is specially a kind of ultraviolet flame monitoring device.
(2) technical background
The flame monitoring apparatus purposes is very extensive, as various be the industrial furnace such as industrial furnace, metallurgical furnace, boiler, pyrolysis furnace, incinerator, heating furnace of fuel with combustion gas, oil, coal dust, the torch of petroleum chemical industry and fire fire-fighting scene etc. all need the details by monitoring grasp flame combustion.This is to enhance productivity and guarantee production safety, and the trouble of anti-fire is in the necessary means of possible trouble.
Traditional flame monitoring apparatus as thermocouple, bimetallic or bulb etc., is to come flame detection by the heat that produces in the monitoring flame combustion process.The time of this class temperature-sensing element reaction in minute.And the discovery of modern flame monitoring apparatus requirement flame failure (as smolder, extinguish, contract fire and fire generation etc.) is with timing second, in time to carry out respective handling.
At present existing multiple contactless flame monitoring apparatus mainly can be divided into optical profile type and camera shooting type.The flame monitoring apparatus of camera shooting type is by the picked-up flame image, carries out image by computer and handles, the stability of judgement flame, shape temperature etc.Though monitoring result is accurate, device is complicated, costs an arm and a leg, and operation requires high, and its application mainly is in the field of study, is difficult to use in the general work occasion.
The optical profile type flame monitoring apparatus has the dissimilar of monitoring visible light, infrared light and ultraviolet light.Industrial furnace has a plurality of burners to form multiple flame region, and the visible light between each flame region reflects mutually, and flame peripheral region (as furnace lining or metallic conduit etc.) also possible Yin Gaowen is luminous.It is the flame detecting device response lag of sensor that these factors make the visible light light-sensitive element, and is difficult to the accurate response flame combustion state.
Infrared radiation in the flame detection, though can reduce the interference of visible light beyond the flame region, heated furnace lining etc. is also sending the strong infrared ray suitable with flame around the flame.This makes that the flame detecting device of infrared ray sensor more is subject to disturb, can't the accurate response flame combustion state.
Amount of ultraviolet irradiation in the flame is directly proportional with flame combustion intensity.When ultraviosensitive UV sensor is received ultraviolet radiation, the pulse signal that output is directly proportional with uitraviolet intensity.External flame monitor adopts this principle mostly, detects the pulse signal power of UV sensor output and monitors the flame combustion situation.Its shortcoming is a UV sensor receiving the interference that the ultraviolet while also can be subjected to X ray, gamma-rays and strong-electromagnetic field, causes misoperation.Generally be to adopt filtering, shaping to handle, this has just reduced the ultraviolet quality of reception, causes general ultraviolet flame sensor can only judge that flame has or not, but can not actual response flame burning situation.Another problem is that UV sensor places the high-temperature region for a long time, and easily aging, the life-span is extremely short, only 6～8 months.Therefore most these type of flame detectors can only be made daylighting at interval, and are out short customs director, open 30～60 seconds passes as 1～2 second.The monitor down periods can't be reacted flame combustion and be changed, and stay very big accident potential.The easy carbon distribution of light inlet window and the coking of this external high-temperature region sensor also influence its operate as normal.
More priorly be, existing flame monitoring apparatus needs near flame when work, generally in 1～3 meter, and the explosion-proof design and the imperfection of device.This just makes the flame monitoring process have unsafe factor to exist.
(3) utility model content
The purpose of this utility model is a kind of ultraviolet flame monitoring device that can telecommute of design, has good explosion-proof, can monitor flame combustion state accurately, in time, neatly.
The ultraviolet flame monitoring device of the utility model design comprises signal picker, UV sensor, signal processing circuit, and signal picker comprises housing, lens, ring cover and bottom.Housing is explosion-proof cylinder, and its top installs convex lens, and ring cover presses lens, and the length of the cross section curve of the field of conjugate action of ring cover and housing meets requirement of explosion proof greater than 20 millimeters.Fixation of sensor circuit board in the housing, the center line of itself and lens coincides.Sensor that receives ultraviolet signal and the pre-process circuit that is attached thereto are arranged on the sensor circuit board.Housing bottom closure casing bottom, the length of the cross section curve of the field of conjugate action of housing and bottom meets requirement of explosion proof greater than 20 millimeters.Explosion-proof fairlead is arranged on the bottom, and the output signal line of sensor circuit board from then on hole is drawn.Lens are in the signal picker case top, and on sensor, sensor receives ultraviolet signal and is converted into level signal output by the circuit that is attached thereto with the ultraviolet rays collection of tested point flame.
Advantage of the present utility model is: 1, signal picker is by explosion-proof criteria design, and each connection place of housing all has greater than 20 millimeters explosion-proof, guarantees safety; 2, signals collecting is at the ultraviolet signal that disturbs in few flame, and assembles and received by special UV sensor through lens, makes this device sensitivity height, to the monitoring of flame accurately and timely; 3, this device still can be worked at 600 meters of distance field, guarantees safety, has more avoided UV sensor at high temperature too fast aging; 4, signal picker can rotate on bracing frame, is convenient to regulate, and aiming needs the place of monitoring; 5, signal picker is connected with the signal transmitting device, the ultraviolet pulse simulation signal of sensor output can be converted to data signal, is connected use with various display unit or control device, is convenient to further expanding and upgrading of this device; 6, but the multiple accessory of this device flexible configuration is applicable to the flame monitoring and the regulation and control of varying environments such as various industrial furnaces, fire fire-fighting and torch; 7, this device is simply small and exquisite, and cost is low, is suitable for popularizing use in various occasions.
