Description
Technical field
The utility model relates to vacuum acquiring system field, is specifically related to a kind of vacuum acquiring system gas analysis and controls device for carrying out said.
Background technology
Vacuum acquiring system is widely used in metallurgy, chemical field, and it comprises vacuum tank, fly-ash separator, vacuum pump system, gas analyzer, pressure instrumentation, vacuum pipe, emptying pipe etc.Quick and precisely analyze the gas ingredients discharged in its vacuum tank is the key controlling vacuum acquiring system.It is analyze by carrying out detection at emptying pipe end installing gas analyser to the gas ingredients that vacuum pump group is discharged that current vacuum obtains Systematical control, controls after Determination result to vacuum acquiring system.The gas that in such vacuum tank, material discharges under vacuum, need experience vacuum pump group to compress step by step could to arrive end gas discharge tube to be discharged in air, the gas ingredients now obtained detects analysis result and relatively lags behind, and unavoidably to suck other gas in vacuum pump evacuation process, emptying pipe is connected with air and is also inevitably mixed into air, gas ingredients is caused to change a lot, cannot ensure quick and precisely to analyze, be difficult to reach and control vacuum acquiring system with the change of vacuum tank composition of gases within, go the object meeting various product processes requirement.
Summary of the invention
For overcoming described deficiency, the purpose of this utility model be to provide a kind of by the gas gas analysis of components initial time discharged in vacuum tank in advance, shorten vacuum acquiring system to gas ingredients in vacuum tank change control response time, reach detection real-time fast and analyze gas ingredients change in vacuum tank and the vacuum acquiring system gas analysis control device for carrying out said precisely controlling vacuum acquiring system with this.
The utility model solves the technical scheme that its technical matters adopts: a kind of vacuum acquiring system gas analysis controls device for carrying out said, comprise vacuum tank, fly-ash separator, vacuum pump group, described vacuum tank is connected by vacuum pipe one with between fly-ash separator, be connected by vacuum pipe two between described fly-ash separator with vacuum pump group, described vacuum pipe two is provided with laser gas analyzer, pressure instrumentation, described laser gas analyzer, pressure instrumentation is connected with PLC input end respectively, described PLC again respectively with vacuum pump group, source purge gas gauge tap is connected, described source purge gas gauge tap is connected with source purge gas, described source purge gas is provided with purging tracheae, the other end purging tracheae aims at laser gas analyzer camera lens, source purge gas switch controls source purge gas according to the signal received, laser gas analyzer camera lens is blown, prevent dust stratification impact analysis precision.
The utility model has following beneficial effect: by selecting laser gas analyzer, and by preposition for gas analyzer before the nucleus equipment vacuum pump of vacuum acquiring system, by time advance initial for Analysis On Gaseous Constituents, shorten vacuum acquiring system and gas ingredients in vacuum tank is changed to the response time controlled; Real-Time Monitoring is carried out to the gaseous tension in vacuum pipe two, monitoring result is fed back to PLC, PLC gas pressure change, control source purge gas gauge tap, source purge gas gauge tap controls source purge gas, when force value in vacuum pipe two is higher than when equaling setting value, sweep gas source of the gas gauge tap is opened, and starts to purge; When in vacuum pipe two, force value is lower than setting value, sweep gas source of the gas gauge tap is closed, stop carrying out purging to laser gas analyzer camera lens to clean, reduce the gas analysis control method entering the gas flow vacuum acquiring system of vacuum acquiring system, make vacuum acquiring system to wherein material bubbing Composition Control is more accurate.
Accompanying drawing explanation

Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.
According to Fig. 1, a kind of vacuum acquiring system gas analysis shown in Fig. 2 controls device for carrying out said, comprise vacuum tank 1, fly-ash separator 3, vacuum pump group 7, described vacuum tank 1 is connected by vacuum pipe 1 with between fly-ash separator 3, described fly-ash separator 3 is connected by vacuum pipe 26 with between vacuum pump group 7, described vacuum pipe 26 is provided with laser gas analyzer 4, pressure instrumentation 5, described laser gas analyzer 4, pressure instrumentation 5 is connected with PLC 8, to PLC 8 input signal, described PLC 8 respectively with vacuum pump group 7, source purge gas gauge tap 9 is connected, described source purge gas gauge tap 9 is connected with source purge gas 10, described source purge gas 10 is provided with and purges tracheae 11, the other end purging tracheae 11 aims at the camera lens of laser gas analyzer 4, source purge gas switch 9 controls source purge gas 10 according to the signal received, the camera lens of laser gas analyzer 4 is blown, prevent dust stratification impact analysis precision.
Principle of work is:
Laser gas analyzer 4 is arranged on the vacuum pipe 26 between fly-ash separator 3 in vacuum acquiring system and vacuum pump group 7, when vacuum pump is started working, laser gas analyzer 4 starts to carry out constituent analysis to gas in vacuum pipe 26, analysis result is fed back to PLC 8, PLC 8, according to analysis result comparison manufacturing technique requirent, controls vacuum acquiring system.
Simultaneously, pressure instrumentation 5 is arranged on the vacuum pipe 26 between fly-ash separator 3 in vacuum acquiring system and vacuum pump group 7, Real-Time Monitoring is carried out to the gaseous tension in vacuum pipe 26, monitoring result is fed back to PLC 8, PLC 8 gas pressure change, control source purge gas gauge tap 9, source purge gas gauge tap 9 controls source purge gas 10, when force value in vacuum pipe 26 is higher than when equaling setting value, sweep gas source of the gas gauge tap 9 is opened, and starts to purge; When in vacuum pipe 26, force value is lower than setting value, sweep gas source of the gas gauge tap 9 is closed, and stops carrying out purging to laser gas analyzer 4 camera lens and cleans, reduce the gas flow entering vacuum acquiring system.
