Abstract
The utility model discloses a leakage detecting device of a urea synthesizing tower. At each tower section, impressed air enters a cavity between the exterior of an inner barrel of the synthesizing tower and a shell through a pipeline and a leakage detecting hole, and then, is connected with a gas analyzer and a signal processing system by another leakage detecting hole and another pipeline. When the leakage occurs, a leaked medium enters the gas analyzer to be analyzed along with the impressed air which; the on-line detection is realized by the signal processing system; and when the control parameter of the leaked medium reaches a set value, alarm can be given immediately to prompt people to treat the leakage in time. The leakage detecting device of the urea synthesizing tower is also applicable to other pressure containers provided with the inner barrels and reinforcing layers with vent holes.
Description
Technical field
The present invention relates to indicate, the device of metering or monitor force vessel safety situation, specifically a kind of urea synthesizer leakage detection apparatus.
Background technology
Urea synthesizer is the large-scale key equipment of urea production; Not only bear HTHP; And inner working media has strong corrosivity; We can say that this type pressure vessel all might cause that internal layer leaks, and cause a serious accident thus because of the expansion of crackle, the factors such as corrosion of medium in long-term use.Safe, reliable, the long-time running of guaranteeing this equipment is the target that fertilizer industry is pursued.Yet, check that at present the main way whether urea synthesizer leaks remains the walkaround inspection by operating personnel, human factor influence is bigger, leakage can not in time be found and leads to serious consequence.In fact, there had been the man chemical fertilizer factory of number in China because of urea tower internal layer seriously corroded leaks in recent years, caused tens of days stopping production loss; The serious accident of urea tower blast has taken place in the producer that also has, and has caused personnel's injures and deaths, and economic loss is huge especially, has caused people's very big concern and attention.
It is outside this type container, to add the seal protection shell that prior art has a kind of; In shell, extract the safety monitoring and protecting system used for pressurized containers that leaking medium is also analyzed with aspiration pump; Adopt this technology; Need wait until after leak taking place that leaking medium could obtain analytic signal between container inner core and containment vessel, run up to a certain degree after effectively, lag time is longer, and can not reflect the development of inner core leakage.For urea synthesizer, this technology has tangible limitation.
The utility model content
The purpose of the utility model is to provide a kind of urea synthesizer leakage detection apparatus, can in time find the on-line measuring device of the safety condition of urea synthetic tower that the synthetic tower inwall leaks, instrument shows, reports to the police and in time handles.
For achieving the above object; The technical scheme of the utility model is: a kind of urea synthesizer leakage detection apparatus; Comprise the inner core of urea synthesizer and outside containment vessel thereof, the leak hunting aperture of containment vessel both sides respectively with containment vessel and inner core between cavity be communicated with, in each tower section; Be respectively equipped with inlet end and add the stop valve that air communication, exhaust end are communicated with flowmeter, the exhaust end of flowmeter links to each other with cavity through the leak hunting aperture of synthetic tower one side; The leak hunting aperture of opposite side connects gas analyzer through choke valve, and the exhaust end of gas analyzer connects bleeder pipe and signal processing system more respectively.
Further, be equipped with leak hunting aperture on every layer of said urea synthesizer tower section.
When adopting technique scheme; In case the inner core of urea synthesizer leaks; The medium that leaks is added air immediately and is taken to gas analyzer, and have or not and the high low energy of leaking medium content reflects that in time the situation of leaking takes place the inner core of urea synthesizer, and has significantly reduced lag time; The variation of leaking medium content can reflect the development of leakage situation in the outrigger air, for the choose reasonable treatment measures provide foundation and opportunity; Because reaction is quick, lag time is short, and many detection lines can be installed on same urea tower, with a cover gas analyzer to each circuit change detection, in time to confirm the position of generation leakage on the inner core; Signal handling equipment or production control system are reported to the police with the setting value that related parameter is arranged and other operation based on the detection signal of leaking medium, realize the online detection and the monitoring of inner core safe condition.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation:
Fig. 1 is the structural representation of the utility model urea synthesizer leakage detection apparatus embodiment.
The specific embodiment
Shown in Fig. 1; A kind of urea synthesizer leakage detection apparatus of the utility model; Comprise the inner core 1 of urea synthesizer and outside containment vessel 2 thereof, the leak hunting aperture of containment vessel 2 both sides respectively with containment vessel 2 and inner core 1 between cavity be communicated with, in each tower section; Be respectively equipped with inlet end and add the stop valve 6 that air 4 is communicated with, exhaust end is communicated with flowmeter 5, the exhaust end of flowmeter 5 links to each other with cavity through the left side leak hunting aperture 31 of synthetic tower; Right side leak hunting aperture 32 connects gas analyzer 8 through choke valve 7, and the exhaust end of gas analyzer 8 connects bleeder pipe 9 and signal processing system 10 more respectively.
Leak if occur; Add air 4 through stop valve 6; Flowmeter 5, advance the left side leak hunting aperture 31 of people's urea synthesizer, just together leak hunting aperture 32 flows out tower bodies to the leaking medium in the leakage point from the right side with adding air 4, gets into gas analyzers 8 along pipeline 4 through choke valve 7.Gas analyzer 8 is discharged by bleeder pipe 9 after having analyzed leaking medium content.Detection signal then is sent to signal processing system 10.Choke valve 7 makes and adds air 4 flows size appropriateness and keep stable; Then the detection signal of gas leakage content and variation thereof has reflected the leakage situation of inner core 1, and the variation that adds air 4 flows can reflect the accumulation in groove of solid, liquid body leakage and corrosion product.
Above-described only is the preferred implementation of the utility model; Should be understood that; For a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement; These also should be regarded as the protection domain of the utility model, and these can not influence effect and practical applicability that the utility model is implemented.
