The utility model solves the problems of easy misoperation, easy pollution, no possibility of touching high temperature, etc. of the ultraviolet photosensitive tube-type flame monitors at present, and therefore, the safe operation of the combustion device is ensured. The automation control of the combustion process is easy to realize, and the production cost of the utility model is only two thirds of the ultraviolet photosensitive tube-type flame monitors.
Description
The utility model relates in a kind of gas industry burner combustion process igniting, flame monitoring apparatus automatically, belongs to a kind of flame combustion sensor.
At present domestic industrial furnace cellars for storing things are gone up the combustion sensor that uses and are the photosensitive pipe flame monitor of ultraviolet ray, and there is following deficiency in the photosensitive tubular type flame monitor of this ultraviolet ray:
1, easily misoperation.Generally speaking, many burners are housed all on most industrial furnaces, and many little flame-out situations that break down simultaneously of burner.When wherein a burner stops working because of taking off fire or tempering, the photosensitive tube that is contained on this burner receives the ultraviolet ray that contiguous operate as normal burner flame sends sometimes, thereby can not in time send flame-out alarm signal of this burner or ignition signal again, the direct result of this misoperation can cause combustion position out of control, has explosion danger when serious.
2, vulnerable to pollution and malfunctioning.The photosensitive pipe flame monitor of ultraviolet ray is done with light-motor science and engineering, so good printing opacity condition is necessary.The carbon black that the coal gas that feeds in the burner, imperfect combustion produce all can pollute photosensitive tube transparent glass surface, makes photosensitive tube not receive the ultraviolet light wave that in fact exists.And think that burner is flame-out by mistake, the concurrent signal that is out of order.
3, can not contact high temperature.Burner is at high temperature to work.And ultraviolet photosensitive pipe can not directly contact high temperature, need consider the high temperature protection measure during use, as not considering, then need be installed in the low temperature position, and this brings many difficulties just for actual the use.
On the external industrial burning device infrared ray or ultraviolet photosensitive tubular type flame monitor are housed mostly.The automatic ignition flame monitoring device of relevant other form, non-avaible introduction does not still at present find relevant patent report yet.
The purpose of this utility model, be that igniting, flame monitoring apparatus automatically will be provided in a kind of new industrial burning device combustion process, it can guarantee the burner safe operation effectively, and the automation of being convenient to combustion process is controlled, its principle is: when fuel combustion, to produce ionization phenomena in flame, this moment, the molecule fission was cation and anion state, was called gas and was at high temperature swashed conduction.At this moment, if add a direct current electric field, will produce electric current at ionized region.After fray-out of flame, electric current disappears with ionization phenomena.
Concrete structure of the present utility model is provided by following examples and block diagram 1, line map 2.
Electric field flame monitoring, automatic ignition device are seen block diagram 4, it connects amplifier 2 by power supply 1, connect flame monitoring probe 3 by amplifier, and be communicated with ignition system 5 and the ignitor 6 of carrying out relay 4 and external power supply connection successively, form with the burner shell of ground connection.
