Abstract
The utility model relates to a natural gas trace metal sampler for enriching some trace metal elements in the natural gas and ensuring that the concentration the trace metal elements reaches the lower limit of an atomic absorption spectrometer. A natural gas conveying pipeline is connected with a gas inlet valve 4, a pressure gauge 3, a regulating valve 6, a float gauge 12, an emptying valve 7 which is connected in parallel and a master valve 5. A pipeline of the main valve 5 is also connected with a quality flow meter 2 with an electronic meter 23 and a filter 19; a plurality of layers of filtering membranes and partitioned filtering nets is arranged in the filter 9, wherein, the trace metal particles in the natural gas are enriched on the filtering membranes, because of the special treatment of the filtering membranes. Then, the content of the trace metal particles can be tested through the spectrometer.
Description
The utility model relates to and is used for the on-the-spot enrichment sampling apparatus that petroleum chemical industry is analyzed rock gas minor metallic element content, belongs to rock gas trace meter sampling instrument.
Along with developing rapidly of petrochemical complex industry, rock gas is widely used in the Chemical Manufacture, and it can be used to do fuel, raw material etc.Find to have some trace meter compounds in the rock gas in the production practices process, it mainly exists with gasoloid or particle form.The colloidal solid form is polymolecular aggregate, is difficult for being absorbed liquid and absorbs or be absorbed pipe institute detention.The perishable pipeline of some trace meter compounds in the rock gas, chemical plant, some also can make catalyst poisoning.Because minor metallic element content very little (ppb) level can't adopt analytical instrument directly to detect in the rock gas, does not find the on-the-spot enrichment sampling apparatus of rock gas trace meter content at present as yet.
The purpose of this utility model is to provide a kind of can improve the sampling instrument of concentration effect to some trace metal elements in the rock gas, makes the concentration of the metallic element of being gathered reach the lower limit that detects of Atomic Absorption Spectrometer or other detector.
The purpose of this utility model can reach by the following technical programs: be connected to gas admittance valve, tensimeter, variable valve, float meter and atmospheric valve and main valve in parallel on defeated natural gas line, on the pipeline of main valve, be connected to the mass flowmeter of charged sub-meter and the filtrator of sealing again, which floor filtering membrane is housed in this filtrator, constitutes the sampling instrument of housing.
In the above-mentioned filtrator two-layer filter membrane can be arranged, between two-layer filter membrane,, can adopt through tygon pyridine oxide and glycerine to add the impregnated filtering membrane of water agitating solution every accompanying two-layer filter screen.The sampling instrument of this sealing, gas in the scheduled time, carry out cumulative measurement to gas volume at meter electronics through mass flowmeter: use the filter membrane of special processing can trap less than trace meter in the rock gas in filter membrane aperture, thereby can realize this purpose.
The utlity model has following characteristics: volume is little, and compact conformation is made casing, is convenient to on-site sampling.Be not subjected to gaseous tension, Temperature Influence in scene temperature and the pipeline.Because mass flowmeter is housed, the gas volume of being gathered can be converted, directly metering.Because the filtering membrane of special processing is housed in the filtrator, can reaches 90% to the collecting efficiency of fine particle composition, colloid in the rock gas, and not be subjected to acquisition target to have the influence of form.Repdocutbility is good, and is easy and simple to handle, and the sampling time is realized control automatically, alleviates working strength.Also be applicable to enrichment to metallic compound in other gas.
Accompanying drawing the 1, the 2nd, this sampling instrument outward appearance master looks and left view;
Accompanying drawing 3 is this sampling instrument structural representations;
Accompanying drawing 4 is filtrator 11 sectional views on Fig. 3.
The utility model is described in further detail below in conjunction with inciting somebody to action shown in the accompanying drawing 4:
In conjunction with the accompanying drawings shown in 4, gas enters 1 li of housing through sampling instrument air intake opening 10 in the transport gas pipeline by accompanying drawing 3, is connected to gas admittance valve 4, tensimeter 3, variable valve 6, float meter 12, air release 7 and main valve 5 in parallel on the pipeline in the housing; Connect mass flowmeter 2 that has meter electronics 23 and the filtrator 19 that seals on the pipeline of main valve 5 again, filtrator is equipped with which floor filtering membrane (17,21) for 19 li.
Above-mentioned filtrator can have two-layer filter film (17,21) for 19 li, reaches the air inlet side and accompany two-layer filter screen (18,20) again at interval between two-layer filtering membrane (17,21); Filter membrane and filter screen are the disk shape, between with O type sealed picture (15,16,22) packing, then filtrator 19 is sealed with lid 14 bolt 13 of screwing on.Can adopt through tygon pyridine oxide and glycerine to add the impregnated filtering membrane of water agitating solution (17,21), improve metallic element effect in the enrichment rock gas.On atmospheric valve 7, connect bleeder pipe 9 in addition, be connected to bleeder pipe 8 on the filtrator 19.Carry handle 11 for conveniently guiding and supporting to be equipped with on the sampling instrument.Mass flowmeter 2 and float meter 12 are buying profiled members, and meter electronics 23 is equipped with in mass flowmeter 2 the insides.Earlier main valve 5 cuts out during use, rock gas is entered by import 10, utilize valve 6 to regulate gas discharge, treat flow reach desired value and stable after, open main valve 5 and close atmospheric valve 7, at this moment, rock gas enters mass flowmeter 2, in meter electronics 23 Preset Times, the rock gas volume is carried out cumulative measurement; Rock gas is by filtrator 19, and filtering membrane can fully absorb and dissolve fine particle composition to be measured, makes the concentration of the element of institute's enrichment reach the lower limit that detects of Atomic Absorption Spectrometer or other detector, and filter back gas is emitted fast through gas outlet 8.Each control valve on this sampling instrument (4,5,6,7) and demonstration are observed parts and all are contained in surface of shell, with handled easily and observation.
