[0002] The online analysis sample pretreatment system of the coal liquefaction plant is the primary part of the entire online analysis system. Its quality and processing capacity directly affect the length of the analysis cycle and the accuracy of the analysis results. For coal liquefaction samples with high temperature, high water and high dust, the cooling, water removal and dust removal cannot reach a very ideal state. The existence of impurities in the sample will reduce the accuracy of the analytical instrument and even damage the instrument.

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 controlmachine 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, removingwater 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.
Description
technical field [0001] The invention relates to an on-line analysis sample pretreatment system of a coal liquefaction device, especially an on-line analysis sample pretreatment system of a high-temperature, high-water, and high-dust coal liquefaction device. Background technique [0002] The online analysis sample pretreatment system of the coal liquefaction plant is the primary part of the entire online analysis system. Its quality and processing capacity directly affect the length of the analysis cycle and the accuracy of the analysis results. For coal liquefaction samples with high temperature, high water and high dust, the cooling, water removal and dust removal cannot reach a very ideal state. The existence of impurities in the sample will reduce the accuracy of the analytical instrument and even damage the instrument. Contents of the invention [0003] The object of the present invention is to provide an on-line analysis sample pretreatment system for a coal liquefac...
