Abstract
The utility model relates to a synthesized ammonia tail gas recovering system. A water-seal flame-retardant device A and a water-seal flame-retardant device B which are connected in parallel are arranged behind a methane recovering device, wherein a gas holder is arranged behind the water-seal flame-retardant device, the methane recovering device is connected with the parallel connected water-seal flame-retardant devices A and B through pipelines; a valve is respectively arranged before a boiler, the gas holder, the water-seal flame-retardant device B and the water-seal flame-retardant device B and behind the methane recovering device. According to the synthesized ammonia tail gas recovering system, tail gas which is directly emitted into the air previously is recycled, so that resources can be saved, production cost can be reduced, pollution to the environment in the production process can be greatly reduced, and the aim of comprehensive utilization can be achieved.
Description
Technical field
The utility model relates to a kind of recovery synthetic ammonia tailgas system.
Background technology
At present, the gas of getting rid of from synthetic tower in the building-up process of ammonia, (main component is CH to can be used for producing natural gas liquids
4) and argon gas, under the normal condition of production, after separated natural gas liquids and argon gas, putting into airborne tail gas content is 2000～2500Nm
3/ h, tail gas Main Components is H
2(approximately 28%), N
2(approximately 53%), CH
4(approximately 4%), O
2with Ar(approximately 15%), H in this tail gas
2, N
2gas content is the highest, directly puts into air, recycles, and not only causes the wasting of resources, and air is caused to very large pollution.
Summary of the invention
The utility model object is to provide a kind of system of recovery synthetic ammonia tailgas of simple in structure, easy construction, the tonifying Qi using the tail gas reclaiming as synthetic ammonia or as the combustion-supporting gas of boiler.
To achieve these goals, the utility model is by the following technical solutions:
A kind of recovery synthetic ammonia tailgas system, water-sealing fire-retardant device A in parallel and water-sealing fire-retardant device B are set after methane recovery device, after water-sealing fire-retardant device B, gas holder is set, described methane recovery device adopts pipeline to be connected with water-sealing fire-retardant device A in parallel with water-sealing fire-retardant device B, is provided with valve before boiler, gas holder, water-sealing fire-retardant device B, water-sealing fire-retardant device A and after methane recovery device.
Described pipeline is carbon steel pipe.
Compared with prior art, the utility model has increased the recycling system of synthetic ammonia tailgas, will originally directly put into airborne tail gas and reclaim, and its yield is about: hydrogen 400Nm
3/ h, nitrogen 750Nm
3/ h, using the hydrogen reclaiming as boiler auxiliary combustion gas or using hydrogen and nitrogen as the tonifying Qi of Ammonia Production unstripped gas, has not only saved resource, has reduced production cost, and has greatly reduced the pollution of production process to environment, reaches the object of comprehensive utilization.
Accompanying drawing explanation
Fig. 1 is the utility model schematic flow sheet;
In figure: methane recovery device 1, valve 2, water-sealing fire-retardant A3, water-sealing fire-retardant B, gas holder 5, boiler 6.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
