Description
Technical field
The invention belongs to residual coking ammonia water oil removal treatment technical field, specifically a kind of remained ammonia cyclone deoiling system.
Background technology
Coal in Jiao's refining process, the remained ammonia that contained external and free moisture and constitution water become materials such as containing tar, ammonia, sulfide, prussiate, volatile phenol in the mixed coal in the gas purification process.Usually the coal-tar middle oil content of formed remained ammonia is 100～300mg/L in the gas purification process, generally carry out oil removing by static oil removing, solvent dephenolize oil removing, oil eliminator oil removing, air flotation oil remover oil removing and ceramic membrane except the wet goods mode for contained tar in the remained ammonia, but these deoiling method deoiling effects are bad, general the highlyest can only reach 60% oil removal rate.In addition, because contained material is more assorted in the remained ammonia, be easy to cause emulsion, so that the oil-containing in the remained ammonia is higher, oleaginousness even up to 300mg/L affects the remained ammonia treatment process sometimes, the easy like this obstruction that causes pipeline, equipment, the safe and stable operation that impact is produced has more increased the tar loss, has reduced the tar rate of recovery.How effectively to reduce the coal-tar middle oil content of remained ammonia, improve the coal-tar middle oil recovery utilization rate of whole recovery system, become the present problem that needs solution.
Summary of the invention
Technical problem solved by the invention has provided a kind of remained ammonia cyclone deoiling system, and it can realize the sharp separation of ammoniacal liquor and tar, and deoiling effect is good, and the tar rate of recovery is high, can effectively reduce the oleaginousness in the remained ammonia.
For solving the problems of the technologies described above, remained ammonia cyclone deoiling of the present invention system, it is characterized in that, comprise mechanical settling tank, remained ammonia medial launder, remained ammonia groove, liquid liquid cyclone separator, net surplus ammonia vessel, tar groove, described mechanical settling tank is connected with the remained ammonia medial launder, be provided with the remained ammonia pump between described remained ammonia medial launder and the remained ammonia groove, described remained ammonia pump is connected remained ammonia medial launder and remained ammonia groove by the water inlet pipe that arranges on the remained ammonia pump respectively with rising pipe; Also be provided with a remained ammonia pump between described liquid liquid cyclone separator and the remained ammonia groove, described remained ammonia pump is connected respectively in the oil-containing remained ammonia entrance of remained ammonia groove and liquid liquid cyclone separator by water inlet pipe and the rising pipe that arranges on the remained ammonia pump, also be provided with net surplus ammoniacal liquor relief outlet and concentrated tar relief outlet on the described liquid liquid cyclone separator, described net surplus ammoniacal liquor relief outlet links to each other with the tar groove with the net surplus ammonia vessel respectively with concentrated tar relief outlet.
Described liquid liquid cyclone separator comprises entrance, undergauge section, cone section and parallel-segment.
Described oil-containing remained ammonia entrance tangentially is arranged on entrance one side of liquid liquid cyclone separator.
The invention has the beneficial effects as follows: the present invention adopts efficient cyclone separator to realize the remained ammonia oil removing, this remained ammonia cyclone deoiling system has realized that by liquid liquid cyclone separator tar and the further of remained ammonia separate on the basis of the static oil removing of remained ammonia.Adopting this system that remained ammonia is carried out oil removing neither increases running cost, has improved again oil removal efficiency, can obviously reduce the oleaginousness in the remained ammonia, also can effectively reclaim tar contained in the remained ammonia simultaneously.
This remained ammonia cyclone deoiling system have technique simple, reliable, do not increase running cost, the series of advantages such as floor space is little, and operating maintenance is simple and convenient, and level of automation is high, oil removal efficiency is high.
