Description
Technical field
The utility model belongs to field of gas detection, the monitoring system of its flue gas being carried out to on-line checkingi after especially a kind of dangerous waste incineration.
Background technology
In today of industrial boom, environmental problem has become the most important thing, national environmental protection mechanism is also more and more higher for the environmental requirement of large industrial enterprise, and among this, the flue gas that trash burning produces can say that the harm for environment is quite huge, therefore the flue gas that national environmental protection mechanism necessarily requires enterprise to discharge must reach certain degree and just can directly enter in air, otherwise just must carry out environmental protection rectification, now a lot of enterprise all can have flue gas to discharge, and the flue gas inspection mode adopted at present all compares old stuff, artificial laboratory is set substantially, chemically examine by after lab technician's spot sampling, to the acidity of flue gas, the parameters such as humidity are chemically examined one by one, such mode is not only loaded down with trivial details, and testing result error is large, guidance for scene can produce some unnecessary impacts.
Utility model content
Based on above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of online flue gas monitoring system with online auto monitoring Gas Parameters.
For achieving the above object, the utility model is by the following technical solutions:
Smoke on-line monitoring system, comprise the throttling valve of the flue for connecting incinerator, sampler chamber, monitoring room, central processing unit, PLC, display instrument and communicator, incinerator connects sampler chamber by throttling valve, sampler chamber connects monitoring room, monitoring room is connected with central processing unit, and central processing unit signal connects display instrument input end; Described monitoring room comprises the ultraviolet spectrometer (UVS) adopting ultraviolet difference absorption spectroscopy techniques flue gas to be carried out to monitoring analysis; Described display instrument is the display instrument for showing the fume sample data message after flue gas analyzer detection and central processing unit process in sampler chamber, display instrument output terminal is connected with PLC, and the control signal of PLC is by communicator feedback link to described incinerator.
As preferably, described display instrument is made up of acidity display instrument and humidity display instrument.
As preferably, described communicator is DCS communicator.
As preferably, in described sampler chamber and monitoring room, be provided with temperature controller.
As preferably, be equipped with in described monitoring room and purge time and the Air Reverse blow device purging number of times can be set.
Compared with prior art, the beneficial effects of the utility model:
The utility model by sampling part, detecting portion, processing section, display section and communication part cooperatively interacted for the on-line checkingi of flue gas, and adopt ultraviolet difference absorption spectrum to detect for flue gas, detection speed is fast, result is accurate, can the production of very accurate guide field.
Accompanying drawing explanation
Fig. 1 is structured flowchart of the present utility model.
In figure: incinerator-1, throttling valve-2, sampler chamber-3, monitoring room-4, central processing unit-5, acidity display instrument-61 and humidity display instrument-62, PLC control system-7, communicator-8.
Embodiment
Consult Fig. 1, the utility model comprises sampling part, detecting portion, processing section, display section and communication part, particularly, the smoke on-line monitoring system of the present embodiment, comprises the throttling valve 2 for connecting incinerator 1 flue, sampler chamber 3, monitoring room 4, central processing unit 5, PLC7, display and communicator 8.
Incinerator 1 connects sampler chamber 3 by throttling valve 2, and sampler chamber 3 connects monitoring room 4, and monitoring room 4 is connected with central processing unit 5, and central processing unit 5 signal connects display input end.Monitoring room 4 comprises the ultraviolet spectrometer (UVS) adopting ultraviolet difference absorption spectroscopy techniques flue gas to be carried out to monitoring analysis, and particularly, monitoring room 4 medium ultraviolet spectrometer is connected with central processing unit 5 signal.And aforementioned display device is the display for showing the fume sample data message after flue gas analyzer detects and central processing unit 5 processes in sampler chamber 3, display output terminal is connected with PLC7, and the control signal of PLC7 passes through communicator 8 feedback link in incinerator 1.In order to control sampler chamber 3 and monitoring room 4 room temperature well, in the sampler chamber 3 of this practicality and monitoring room 4, be provided with temperature controller.In addition, monitoring room 4 of the present utility model is equipped with and can arranges purge time and the Air Reverse blow device purging number of times.
In addition, above-mentioned display instrument is made up of acidity display instrument 61 and humidity display instrument 62, can personal monitoring's acidity and moisture signal, and acidity and moisture signal are sent in PLC7 as digital signal by more the most important thing is certainly acidity display instrument 61 and humidity display instrument 62.
Above-mentioned communicator 8 is DCS communicators, i.e. local communication terminal, is mainly used in the control signal receiving PLC, is mated by the signal of this signal as on-the-spot topworks.
The utility model in the course of the work, incinerator 1 flue gas out enters in sampler chamber 3, monitoring room 4 is entered carry out brief stay process in sampler chamber 3 after, by monitoring room 4 medium ultraviolet spectrometer, it is detected, data are analyzed through central processing unit 5, process after testing result is shown over the display, display result is sent to PLC7, by analysis after process, send control signal, control signal is sent in incinerator 1 by DCS communication, by so monitoring flow process the carrying out instructing whole burning process.Here incinerator 1 of the present utility model can adopt electrical heating incineration stove, also fuel and oxygen mix burning can be adopted to burn, also other modes well known to those skilled in the art can be adopted to burn, electrical heating incineration stove can change burning intensity by control voltage, and the flow that fuel combustion can control fuel by operation valve changes burning intensity.Therefore, PLC7, according to the input of signal, first to DCS communicator 8 transmission signal, then mates incinerator 1 voltage or operation valve by the signal of DCS communicator 8, thus carries out feedback regulation to incinerator 1.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after the utility model simple transformation.
