Background technology
Existing system nitrogen mode has three kinds, i.e. cryogenic air separation method, the empty point-score of molecular sieve and the empty point-score of film.Wherein deep cooling nitrogen production by air separation device is suitable for large-scale industry system nitrogen; Deep cooling nitrogen production by air separation complex equipments, floor space are big, and capital cost is higher, and the equipment one-time investment is more; Running cost is higher; Aerogenesis is slow, and (12～24h), installation requirement is high, the cycle is longer, and the scale of investment of the empty point-score PSA of the molecular sieve of same size device is than deep cooling air separation facility low 20%～50%; The empty point-score of film is suitable for the medium and small nitrogen user of nitrogen gas purity≤98%, and best-of-breed functionality price ratio is arranged, and nitrogen gas purity is 98% when above, and it is compared price with the PSA equipment of making nitrogen of same size and will exceed more than 15%; And the empty point-score technical process of molecular sieve is simple, level of automation is high, aerogenesis is fast, energy consumption is low; Product purity can be regulated according to user's needs in a big way; Characteristics such as convenient operating maintenance, running cost is lower, device flexibility is stronger; So in the following equipment of making nitrogen of 1000Nm3/h, have much competitive power; More and more obtain medium and small nitrogen user's welcome, the empty branch legal system of molecular sieve nitrogen has become medium and small nitrogen user's prefered method, and the raising of its system nitrogen performance becomes current research emphasis gradually.
Summary of the invention
It is a kind of simple in structure, compact that the utility model provides, and system nitrogen is effective, and system nitrogen is stable, but molecular sieve transformation safe in utilization absorption nitrogen-making device.
The technical scheme that the utility model adopts is: but a kind of molecular sieve transformation absorption nitrogen-making device; Connect to form successively by electric control box, air, moisture eliminator, strainer, gas storage holder, nitrogenous generator and storage nitrogen cabinet; It is characterized in that said nitrogenous generator comprises vacuum breaker, throttling valve and first and second carbonaceous molecular sieve system nitrogen cabinet; Vacuum breaker one termination gas storage holder; The other end is communicated with the import of first and second carbonaceous molecular sieve system nitrogen cabinet respectively through first and second switching valve, the import of first and second carbonaceous molecular sieve system nitrogen cabinet is communicated with a gas barrier through first and second vent valve respectively; The outlet of first and second carbonaceous molecular sieve system nitrogen cabinet is communicated with throttling valve one end through first and second steam supply valve respectively, and the throttling valve the other end is communicated with storage nitrogen cabinet; Be serially connected with first equilibrium valve between the import of first and second carbonaceous molecular sieve system nitrogen cabinet, be serially connected with second equilibrium valve between the outlet of first and second carbonaceous molecular sieve system nitrogen cabinet.
Further, be serially connected with nitrogen between the outlet of said first and second carbonaceous molecular sieve system nitrogen cabinet and detect valve.
Again further, said strainer comprises coarse filter and fine filtrator.
Air is by dry, thick through moisture eliminator successively, the dedusting of fine filtrator two-stage filtration after the air compression, and pressurized air is sent into gas storage holder, by gas storage holder through vacuum breaker to the nitrogenous generator air feed; System nitrogen process is made up of first and second carbonaceous molecular sieve system nitrogen cabinet work two portions circulation.
First circulation: system nitrogen; First switching valve is opened; To the first carbonaceous molecular sieve system nitrogen cabinet air feed, the oxygen in the first carbonaceous molecular sieve system nitrogen cabinet absorbed air, non-adsorbable nitrogen pass through first steam supply valve and supply nitrogen by throttling valve to storage nitrogen cabinet pressurized air through vacuum breaker, first switching valve.Exhaust, second vent valve is opened simultaneously, and the oxygen of the second carbonaceous molecular sieve system nitrogen cabinet internal adsorption discharges warp second vent valve to the gas barrier exhaust, and the second carbonaceous molecular sieve system nitrogen cabinet internal pressure becomes normal pressure.All press, behind the exhaust setting-up time, first and second equilibrium valve is opened, and first and second carbonaceous molecular sieve system nitrogen cabinet is realized all pressing, and the oxygen of the first carbonaceous molecular sieve system nitrogen cabinet internal adsorption is divided equally to first and second carbonaceous molecular sieve system nitrogen cabinet.
Second circulation: system nitrogen; After first loop ends; Second switching valve is opened; To the second carbonaceous molecular sieve system nitrogen cabinet air feed, the oxygen in the second carbonaceous molecular sieve system nitrogen cabinet absorbed air, non-adsorbable nitrogen pass through second steam supply valve and supply nitrogen by throttling valve to storage nitrogen cabinet pressurized air through vacuum breaker, second switching valve.Exhaust, first vent valve is opened simultaneously, and the oxygen of the first carbonaceous molecular sieve system nitrogen cabinet internal adsorption discharges warp first vent valve to the gas barrier exhaust, and the first carbonaceous molecular sieve system nitrogen cabinet internal pressure becomes normal pressure.All press, behind the exhaust setting-up time, first and second equilibrium valve is opened, and first and second carbonaceous molecular sieve system nitrogen cabinet is realized all pressing, and the oxygen of the second carbonaceous molecular sieve system nitrogen cabinet internal adsorption is divided equally to first and second carbonaceous molecular sieve system nitrogen cabinet.
Above-mentioned two portions circulation goes round and begins again, and realizes the alternation absorption discharging of nitrogen-making device.
But the utility model nitrogen-making device adopts two carbonaceous molecular sieve system nitrogen cabinet alternate cycles system nitrogen, air feed, exhaust, all presses completion transformation absorption system nitrogen, and it is simple in structure, compact, and system nitrogen is effective, and system nitrogen is stablized, and is safe in utilization, and system nitrogen purity reaches more than 99.5%.
