Description
Technical field
The utility model relates to a kind of recovery ammonia decontamination device.
Background technology
Ammonolysis reaction during thiophene ethamine is produced has a large amount of useless ammonias to produce, and no matter is from economic aspect or environmental protection aspect, all will consider to reclaim.Industrial most useless ammonia treatment process all is that water absorbs, and as a kind of ammonia recovery system ammonia-cleaning tower that CN 202199246 U disclose, its shortcoming is directly to recycle in anhydrous production technique.Also having a kind of useless ammonia treatment process is to be condensed into liquefied ammonia, is directly used in the production, reaches the zero release of ammonia.Ammonia waste gas is condensed into liquefied ammonia, two kinds of diverse ways are arranged again: the one, production technique is with pressure, its not pressure release of ammonia waste gas directly is condensed into liquefied ammonia, the ammonia of the 1.2 ~ 1.5MPa that discloses as CN 101560159 B directly is condensed into liquefied ammonia, its shortcoming is that general production technique is to react under certain pressure, if useless ammonia is normal pressure, just can't use; The 2nd, normal pressure ammonia waste gas is condensed into liquefied ammonia after compression again, as the gas ammonia that CN 1010767B discloses, advance ammonia compressor before, only separate through simple droplet separator, can not fully reduce the moisture in the gas ammonia, unfavorable to compressor.
The fine chemistry industry production technique of the overwhelming majority, all can be with an organic solvent or water make reaction solvent, therefore the useless ammonia that produces will be carried organic solvent or water secretly, directly as the air inlet of compressor, can cause the suburb rate of compressor to reduce and damages.
Summary of the invention
For overcome exist in the existing useless ammonia treatment process because with an organic solvent or water make reaction solvent, cause the useless ammonia of generation will carry organic solvent or water secretly, directly the air inlet meeting as compressor causes the suburb rate reduction of compressor and the shortcoming of damaging, and the utility model provides a kind of has the suburb to prevent that organic solvent or water from entering the recovery ammonia decontamination device that compressor produces wet stroke and liquid hit phenomenon.
The technical solution adopted in the utility model is:
Reclaim the ammonia decontamination device, comprise tower body, it is characterized in that: described tower body comprises the conically shaped of the end socket, first tower joint, second tower joint, the 3rd tower joint and the strap clamp cover that connect by flange successively from top to bottom, described end socket top is provided with inlet mouth, and described the 3rd tower joint top one side is provided with the air outlet;
Described first tower joint comprises that first fixed tube sheet heat exchanger and traverse baffle, described traverse baffle are arranged on the described first fixed tube sheet heat exchanger lower end;
