Abstract
The utility model discloses an empty hydrocarbon analytic system always that divides, including air cleaner, air compressor machine, air cooling machine, molecular sieve, air separation system, empty main cold measurement source, the hydrocarbon analysis appearance of dividing that connects gradually, hydrocarbon analysis appearance front end still is connected with molecular sieve and burning gas device. Change to the air after the molecular sieve washing cooling through the supplementary combustion gas with hydrocarbon analysis appearance, reduced manufacturing cost's consumption, can't carry out continuous monitor and operating guideline to air separation system when having avoided the gas cylinder change, increased the stability of production system.
Description
Technical field
The utility model relates to technical field of automatic control, is specially the air supply processing equipment of total hydrocarbon in-line analyzer.
Background technology
Air separation unit belongs to Continuous Running Equipment, and operational process must carry out on-line monitoring to total carbon content in main cold liquid oxygen, prevents hydrocarbon from gathering in liquid oxygen and causes main cold explosion accident.The total carbon-hydrogen analyzer of present employing carries out on-line monitoring to total carbon content in main cold liquid oxygen, online total carbon-hydrogen analyzer divides the important of explosion-proof monitoring to want means as sky, this analyser adopts hydrogen in the nitrogen of 40%H2 as fuel gas, to adopt the zero level air of 21%O2 as auxiliary fuel air now.The index of zero level air is temperature 4 ~ 45 DEG C, dew point-35 DEG C≤and, dust concentration ≯ 10mg/m, flow >=60L/h, pressure >=220kPa, without oil.During analyser work, required zero level air is supplied by gas cylinder, in use need frequently to change gas cylinder, the necessary off-line of analyser when changing gas cylinder, also need certain hour to debug after replacing and could be unfavorable for empty point of monitoring and Operating Guideline continuously by Restoration monitoring, monthly at least use 2 bottles of zero level air, every bottle of zero level air needs about 1030 yuan, adds production cost.
Utility model content
In order to solve the problems of the technologies described above, the utility model aims to provide a kind of empty point total hydrocarbon analytic system,
The utility model is achieved by following technical solution:
A kind of empty point total hydrocarbon analytic system, comprise connect successively air strainer, air compressor machine, air cooling machine, molecular sieve, space division system, empty point of main cold measurement source, carbon-hydrogen analyzer, described carbon-hydrogen analyzer front end is also connected with molecular sieve and burning gas device.
Filtering pressure reducing valve and needle valve is connected with in turn between described carbon-hydrogen analyzer and molecular sieve.
Gas in described burning gases device is hydrogen in nitrogen.
The beneficial effects of the utility model are:
Compared with prior art, one sky point total hydrocarbon analytic system that the utility model provides, by the auxiliary combustion gas of carbon-hydrogen analyzer being replaced by the air after outlet molecular sieve purification, decrease the consumption of production cost, avoid when gas cylinder is changed and cannot monitor continuously and Operating Guideline space division system, add the stability of production system.
Accompanying drawing explanation
Fig. 1 is system architecture schematic diagram of the present utility model
In figure: 1-filtrator, 2-air compressor machine, 3-air cooling compressor, 4-molecular sieve, 5-space division system, 7-carbon-hydrogen analyzer, 8-burning gas device, 9-needle valve, 10-filtering pressure reducing valve.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further, but described in required protection domain is not limited to;
As shown in the figure, one sky point total hydrocarbon analytic system that the utility model provides, comprise connect successively air strainer 1, air compressor machine 2, air cooling compressor 3, molecular sieve 4, space division system 5, empty point of main cold measurement source 6, carbon-hydrogen analyzer 7, it is characterized in that: described carbon-hydrogen analyzer 7 front end is also connected with molecular sieve 4 and burning gas device 7.
Filtering pressure reducing valve 10 and needle valve 9 is connected with in turn between described carbon-hydrogen analyzer 7 and molecular sieve 4.Needle valve 9 is the controlled valve of secondary combustion air, and filtering pressure reducing valve 10 is the flowrate control valve of secondary combustion air.
Gas in described burning gases device 8 is hydrogen in nitrogen.
The utility model is technical requirement needed for satisfied total carbon-hydrogen analyzer air, design the zero level air of continuous air feed, after adopting air compressor machine compression, air is through water washing and by the impurity in activated alumina and 13X molecular sieve filtration absorbed air, carries out delivering to total carbon-hydrogen analyzer after pressure regulation through RVP404 filtering pressure reducing valve.
The auxiliary air index that this device provides is: temperature 15 ~ 30 DEG C, dew point-70 ~-77 DEG C, dust concentration ≯ 10mg/m, clean without oil, pressure 450kPa, flow > 1000L/h.
After transformation, an empty point total carbon analyzer runs through and carries out measurement of comparison with zero level air, and both displays are all floated at about 20 ~ 30PPm, and transformation can reach instrument service condition completely
The utility model in use, adjusts flow and burning gases 8 by switch needle valve 9 switch secondary combustion air by filtering pressure reducing valve 10 and jointly passes into carbon-hydrogen analyzer 7 and detect by total carbon contained in the isolated liquid oxygen of space division system 5.
