Background technology
The oil refining torch is the important safety and environmental protection facility in refinery, and it is for the treatment of hydro carbons flared gases and sour gas that each device under refinery's shutting down and the accident condition is released, and it changes into CO by burning with these gases
2, H
2The gases such as O, thus minimizing is to the pollution of atmosphere.Its torch is to be lighted by torch altar lamp which burns day and night, so, if torch altar lamp which burns day and night is in and extinguishes state when releasing, then torch just can't successfully be lighted, thereby cause hydro carbons flared gases and sour gas directly to discharge and enter atmosphere, thereby can cause serious consequence, the problem of therefore combustion position of torch altar lamp which burns day and night being monitored just seems extremely important.CN2674305Y discloses a kind of UV flame monitor, can be used for flame monitoring and the regulation and control of the varying environments such as industrial furnace, fire fire-fighting and torch.It is following several that present flame monitor mostly is: (1) adopts the flame monitor of the standard original paper of thermocouple type, it is used for the combustion position of flame is monitored, this kind flame monitor adopts the modes such as ultraviolet ray, thermopair that flame combustion state is monitored, but there is slow, the easily damage of thermocouple monitoring response speed in it, ultraviolet flame monitoring is subject to the meteorological condition impact, and infrared acquisition is to sound electromagnetic wave and vibrations problem such as very responsive all; (2) comprise the ionic flame sensor, the self-sustained oscillation module, the ionic flame detector of rectification detection module and level switch module, this kind flame monitor adopts single-chip microcomputer or customized logic device to realize that the gas appliance flame ion of control detects the ignition controller scheme, ignition electrode is simultaneously as the flame ion inducing probes, the gas utensil flame combustion situation is monitored, it comprises the flame ion detecting ignition controller that is applicable to gas utensil, this kind flame monitor adopts the ionic flame monitoring mode that the combustion position of flame is monitored, it is reliable that it has monitor signal, the advantage of fast response time, but its existence lacks the ionic flame monitoring device is used practicality at torch altar lamp which burns day and night problem.For this reason, need a kind of accuracy and sensitivity good, and be suitable for practical flame ion monitor, satisfy the needs of actual conditions with this.
The utility model content
The utility model provides a kind of flame ion monitor, and whether it exists to judge the fired state of pilot burner by direct monitoring pilot burner flame, solves the problem of existing oil refining torch flame monitoring.
The technical scheme that the utility model adopts is:
The flame ion monitor, comprise ion monitoring signal processing unit and flame ion monitoring means, described flame ion monitoring means is arranged in the pilot burner fuelgas pipeline, and the top of flame ion monitoring means is stretched into and is arranged in the pilot burner burner, and described ion monitoring signal processing unit is connected with the flame ion monitoring means.
In the technical solution of the utility model, also have following additional technical feature:
Described flame ion monitoring means is to be arranged in the pilot burner fuelgas pipeline by the sealed interface that insertion is arranged on the pilot burner fuelgas pipeline.
Described flame ion monitoring means is the ceramic rod that the top is provided with conducting end, and described conducting end stretches into and is arranged in the pilot burner burner.
The conducting end of described ceramic rod is arranged on the conducting position place of pilot burner.
Described ion monitoring signal processing unit is connected by signal wire with the flame ion monitoring means.
Described pilot burner fuelgas pipeline is provided with the coupled fuel gas admission line that communicates.
Described signal wire is cable.
Compared with prior art, advantage of the present utility model and good effect are: flame ion monitor of the present utility model, whether it exists to judge the fired state of pilot burner by direct monitoring pilot burner flame, solve the problem of existing oil refining torch flame monitoring, has response fast, highly sensitive, accuracy is good, the advantage that reliability is high, the fired state that it directly monitors flame, the flame that is applicable to torch altar lamp which burns day and night detects, in a single day flame extinguish, electric current will interrupt, and can be used as immediately the signal source of automatic ignition system, helps to improve the safe operation of torch.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is flame ion monitor structural representation of the present utility model.
Among the figure, 1 is the pilot burner burner, and 2 is the flame ion monitoring means, and 3 is the fuel gas admission line, and 4 is the pilot burner fuelgas pipeline, and 5 is sealed interface, and 6 is the ion monitoring signal processing unit.
Embodiment
Embodiment
As shown in Figure 1, the flame ion monitor comprises ion monitoring signal processing unit 6 and flame ion monitoring means 2, and described flame ion monitoring means 2 is arranged in the pilot burner fuelgas pipeline 4; Described flame ion monitoring means 2 is provided with the ceramic rod of conducting end for the top, and described conducting end stretches into and is arranged in the pilot burner burner 1; The conducting end of described ceramic rod is arranged on the conducting position place of pilot burner; Described ion monitoring signal processing unit 6 and flame ion monitoring means 2 are connected by signal wire; Described flame ion monitoring means 2 is to be arranged in the pilot burner fuelgas pipeline 4 by the sealed interface 5 that insertion is arranged on the pilot burner fuelgas pipeline 4; Described pilot burner fuelgas pipeline 4 is provided with the coupled fuel gas admission line 3 that communicates; Described signal wire is cable.
Like this when work, flame ion monitor of the present utility model, when pilot burner burns, fuel gas enters pilot burner fuelgas pipeline 4 by fuel gas admission line 3, and burning in pilot burner burner 1, this moment, pilot burner burner 1 was inside and outside because the burning of flame, generation has the ionized gas of electric conductivity, and be applied with micro voltage at flame ion monitoring means 2, will produce faint electric current this moment between flame ion probe unit 2 and pilot burner burner 1, just can determine whether to exist flame by the monitoring to this weak current, judge namely whether pilot burner is in fired state, if monitoring is less than electric current, show that then flame does not exist, be that pilot burner is in and extinguishes state, it directly monitors the fired state of flame, and signal is reliable, and its response fast, in a single day flame extinguish, and electric current will interrupt, and can be used as immediately the signal source of automatic ignition system.
Obviously, above-described embodiment of the present utility model only is for the utility model example clearly is described, and is not to be restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here can't give all embodiments exhaustive.Everyly belong to the row that apparent variation that the technical solution of the utility model amplifies out or change still are in protection domain of the present utility model.
