Abstract
The present invention relates to a coal liquefaction device online analyzing sample pretreatment system. The present invention uses a secondary treatment method. A first stage filter comprises a T-shaped filter, a reducing valve and a safety valve. A second stage filter comprises a compressor, a bulk tank and a drier filter in order. The sample inlet of the compressor is connected with the first stage filter. The outlet of the compressor is connected with the inlet of the drier filter through a valve. The water outlet of the compressor is connected with the inlet of the bulk tank. The water outlet is arranged on the bulk tank. A dew point intelligent monitoring and control device comprises automatic valves which are respectively arranged on the sample inlet of a tee filter and the sample inlet pipeline of the drier filter, and a dew point intelligent monitoring and control machine which is arranged on the sample outlet of the compressor. The dew point intelligent monitoring and control machine is used for monitoring the water content in the sample outlet and controlling the interruption of the automatic valves. The coal liquefaction sample is treated by two stage cooling, removing water and dust removal filtration. So the temperature, the water content and the dust content of the sample are ensured to meet the requirement before entering an analytical instrument.

Coal liquification device on-line analysis sample pretreatment system is as the primary part of whole on-line analysis system, the height of its quality and processing power, directly have influence on the length and the precision of analysis of analytical cycle, at present the pretreatment system of on-line analysis on the market for the cooling of the coal liquefaction sample of high temperature, high water and high dirt, dewater, the processing of dedusting can't reach very desirable state, the existence of impurity in the sample, can reduce the accuracy of analysis meter, even damage instrument.
Summary of the invention
The objective of the invention is: a kind of coal liquification device on-line analysis sample pretreatment system that is applicable to high temperature, high water content and high dirt is provided.
The objective of the invention is to realize by the enforcement following technical proposals:
A kind of coal liquification device on-line analysis sample pretreatment system comprises the sample collecting probe, and filtrator is characterized in that: described filtrator adopts two-stage filtration, has pipeline and a plurality of valve to join between the filtration units at different levels; One-level is filtered and is comprised the T type filter; Cascade filtration comprises compressor, liquid collecting jar, device for drying and filtering successively; The sample inlet of compressor and one-level are filtered and are joined, and its sample export joins by the inlet of valve and device for drying and filtering, and the water delivering orifice of compressor links to each other with liquid collecting jar inlet, sets out the mouth of a river on the liquid collecting jar; Also comprise a dew point intellectual monitoring control device, described dew point intellectual monitoring control device comprises the dew point monitoring controller that is separately positioned on the autovalve on T type filter sample inlet and the device for drying and filtering sample inlet pipeline and is arranged on the compressor sample export, and the dew point monitoring controller is used to monitor the liquid water content of sample export and cut-offfing of control autovalve.
The dew point monitoring controller of dew point intellectual monitoring control device is used for the liquid water content of compressor sample export is monitored, when liquid water content is higher, controller disconnects them for automatically the electric signal of autovalve that is separately positioned on one-level filtration and cascade filtration, thereby pretreatment system and sampling and analysis meter are kept apart, when the liquid water content of press proof product outlet to be compressed reaches arm's length standard, open autovalve more automatically.Guarantee that the sample water content after the compressed machine cooling dehydration is lower than preset value, the dew point monitoring controller can be according to the preset value adjustment to the monitoring range of water cut dew point.
The coal liquefaction sample of high-temperature high dust Gao Shui filters through the filtrator of one-level, compressor cooling dehydration and exsiccator through secondary filters again, water and impurity in the sample have effectively been removed, guarantee that the temperature, water cut and the dustiness that enter the preceding sample of analytical instrument reach requirement, ensure the accuracy of instrument measurement and the safety of instrument.
