One part of the utility model is that pressure maintaining valves (1) and chokes (2) are connected with reference arms after the pressure maintaining valves (1) and the chokes (2) are connected; another part of the utility model is connected with waiting slot columns (5) through the pressure maintaining valves and six way sampling valves (3) and then enters into six way passing switching valve (7); then one part of six way sampling valves passes through main columns (8) and another part is communicated with measuring arms of thermal conductivity pools (9) through balance valves (6); the thermal conductivity pools (9) are connected with a signal converter (10) and a printer (12) through a computer (11). The chromatographic column of the utility model effectively separate nitrogen, oxygen, carbon monoxide, and carbon dioxide. Thermal conductivity detectors are used for analyzing the concentration of various air samples, and the percentage of various air samples is gotten from the global calculation by correction factors.
Description
The utility model belongs to analytical equipment field used in the petrochemical complex process, refers more particularly to the improvement to regeneration fume from catalytic cracking express-analysis instrument.
At present, the analysis of regeneration fume from catalytic cracking composition mainly contains two kinds of instruments: (1) Orsat analysis.This is the analytical approach that adopt in present most of refinery laboratory, and its ultimate principle flow process is: the flue gas sample at first by first kind of solution, sponges oxygen wherein, according to volume change, records oxygen content; By second kind of solution, sponge carbon monoxide wherein then,, record the amount of carbon monoxide according to volume change; By the third solution, sponge carbon dioxide wherein again, according to volume change, record the content of carbon dioxide, the content of nitrogen then obtains with subtracting difference.(2) infrared spectrum analyser.This instrument is mainly used in the amount of measuring carbon monoxide and carbon dioxide in the flue gas, calculates the green coke amount thus.And to survey nitrogen and oxygen content is still needed by other analysis means.
The utility model purpose provides a flue gas quick analytic instrument, replaces above-mentioned two kinds of instruments.Because above-mentioned Orsat analysis is a kind of ancient method, major defect is that three kinds of solution need regularly replace, complex operation, and glass apparatus exists system airtight bad, causes analysis precision low, poor repeatability.Shortcomings such as in addition, naked eyes are read volume, and personal error is big.And infrared analysis generally only is applicable to research department, only carbon monoxide in the flue gas and carbon dioxide is measured, and the analysis of oxygen and nitrogen is still needed by other means.At above-mentioned drawback, invention has designed one and has overlapped the thermal conductance detecting instrument-catalytic cracking flue gas quick analytic instrument that has special separating column, and analysis flue gas that can be quick and precisely easy is formed.
The utility model is achieved in that by pressure maintaining valve (1), vapour lock (2), six-way injection valve (3), gauge line (4), cut post (5) in advance, equalizing valve (6), six direction changeover valves (7), principal post (8), conductance cell (9), signal converter (10), computing machine (11), printer (12) is formed, and it is characterized in that: a route pressure maintaining valve (1) is connected the back and links to each other with the reference arm of conductance cell (9) with vapour lock (2); Another road is connected through the inlet 3a of pressure maintaining valve with six-way injection valve (3), one outlet (3f) of six-way injection valve (3) is connected with the inlet of gauge line (4), the outlet of gauge line (4) is connected with an inlet (3e) of six-way injection valve (3), one inlet (3b) of six-way injection valve (3) is connected the back with an outlet (3c) and is connected with a blow-down pipe, the outlet (3d) of six-way injection valve (3) with cut the inlet (7a) that enters six direction changeover valves (7) after post (5) is connected in advance, one outlet (7f) of six direction changeover valves (7) is connected with the inlet of principal post (8), the outlet of principal post (8) is connected with an inlet (7e) of six direction changeover valves (7), one outlet (7b) of six direction changeover valves (7) is connected with import (7c) behind an equalizing valve (6), one outlet (7d) of six direction changeover valves (7) communicates with the gage beam of conductance cell (9), conductance cell (9) is connected with signal converter (10), and machine (11) back is connected with printer (12) as calculated.See accompanying drawing 1.
The flue gas analysis process prescription is as follows: a road in the carrier gas (H2) enters conductance cell (9) after pressure maintaining valve (1) and vapour lock (2) reference arm is as benchmark, and a six-way valve (3) is passed through on another road behind pressure maintaining valve.Under the sample introduction situation, H2 brings quantitative flue gas sample into by gauge line (4) and cuts post (5) in advance, and in this post, carbon dioxide is left, other component (O2, N2, CO) fast by this post behind six direction changeover valves (7) and enter principal post (8).Finish in principal post O2, N2 and CO separate.Then, six direction changeover valves (7) are switched to another road, CO2 is carried in carrier gas this moment will no longer enter thermal conductivity cell detector through principal post by equalizing valve (6) short circuit.So design can be rapidly easily with O2, N2, and CO and separating that CO2 realizes ideal are after signal converter (10), computing machine (11) are handled the back and provided the final analysis result by printer (12).
For realizing above-mentioned purpose, the utility model has designed the chromatographic column that a centre has handoff functionality, can rapidly and accurately the nitrogen in the flue gas, oxygen, carbon monoxide, carbon dioxide thoroughly be separated, measure the percent concentration of four kinds of gases then one by one by thermal conductivity detector (TCD), utilize the correction factor normalizing can try to achieve the ratio of each gas comprises again.
The effect that the utility model reaches:
This instrument has following several characteristics; 1. analysis precision height; 2. dependable performance, repeatability is good; 3. analysis is easy rapidly, and once only analyzing needed get final product in 7-8 minute; 4. the sample use amount is few; 5. automaticity height, behind the gauge line switch sampling, every operation is all finished by computing machine, and printer provides final form result, and can be used for the field of all flue gas analyses.
