The antiblocking sectional type coalescer is used, so that the tar is quickly removed from the surplus ammonia solution, the quick separation of the tar from the ammonia solution can be realized, the tar removing effect is good, the operation is simple, the device is easy to maintain, and the tar content in the surplus ammonia solution can be effectively reduced.
Description
Technical field
The invention belongs to residual coking ammonia water tar separation technology.
Background technology
Can produce a kind of ammoniacal liquor in burnt sweetening process process, external and free moisture contained in mixed coal and constitution water become containing materials such as tar, ammonia, sulfide, prussiate, volatile phenols in gas purification process, are commonly referred to remained ammonia.Usually the coal-tar middle oil content of the remained ammonia formed in gas purification process is 300 ~ 600mg/L, these tar are all absolute objectionable impuritiess to follow-up biochemical system, accumulate over a long period, quantitatively also quite huge, not only waste ample resources, and disadvantageous effect has been caused to normal production.Generally by static oil removing, solvent dephenolize oil removing, oil eliminator oil removing, air flotation oil remover oil removing and ceramic membrane, wet goods mode is removed for tar contained in remained ammonia and carries out oil removing, but these oil removing mode deoiling effects are bad, generally the highest can only reach 60% oil removal rate.Moreover, although tar is fluid in high temperature remained ammonia, cooled in subsequent technique, below 50 DEG C, then become solid, no longer there is mobility, and tar cannot reclaim; In addition, because material contained in remained ammonia is more assorted, be easy to cause emulsion, make the oil-containing in remained ammonia higher, be again oleaginousness even up to 500mg/L, affect remained ammonia treatment process, the easy like this blocking causing pipeline, equipment, the safe and stable operation that impact is produced, further increases tar loss, reduces the tar rate of recovery.How effectively to reduce the coal-tar middle oil content of remained ammonia, improve the recovery utilization rate that whole recovery system is coal-tar middle oil, become current urgent problem.
Summary of the invention
Technical problem solved by the invention there is provided a kind of method of remained ammonia tar separation, can realize the sharp separation of tar and ammoniacal liquor, and deoiling effect is good, simple to operate, is easy to safeguard, effectively can reduce the oil-contg in remained ammonia.
In order to realize above-mentioned effect, a kind of residual coking ammonia water tar-removing device, it comprises remained ammonia groove, remained ammonia pump, antiblocking sectional type coalescer, clear remained ammonia groove, tar groove; Described remained ammonia groove is connected with remained ammonia pump, and described remained ammonia pump is connected with the entrance of antiblocking sectional type coalescer; The clear ammoniacal liquor outlet of antiblocking sectional type coalescer is connected with clear remained ammonia groove; The tar outlet of antiblocking sectional type coalescer is connected with tar groove.
From remained ammonia, a method for separating tar, comprises the steps:
Remained ammonia is sent into remained ammonia groove, after sedimentation, by remained ammonia pump, upper strata remained ammonia is sent into antiblocking sectional type coalescer; In described antiblocking sectional type coalescer, complete the remained ammonia breakdown of emulsion of emulsification shape fast, be then separated ammoniacal liquor and tar; Clear remained ammonia after separation enters remained ammonia groove clearly through the clear remained ammonia outlet of described antiblocking sectional type coalescer, and the tar after separation is back to described remained ammonia groove through the tar outlet of described antiblocking sectional type coalescer; Described tar deposits in a large number in the bottom of described remained ammonia groove, finally discharges described remained ammonia groove.
A device for separating tar from remained ammonia, described device comprises the remained ammonia groove, remained ammonia pump and the antiblocking sectional type coalescer that connect successively;
Described antiblocking sectional type coalescer has remained ammonia outlet and tar outlet clearly;
Described clear remained ammonia outlet is connected with clear remained ammonia groove;
Described tar outlet is connected with described remained ammonia groove;
The bottom of described remained ammonia groove is connected with tar groove.
The height of the height of described tar outlet and the outlet of clear remained ammonia, higher than the height of described antiblocking sectional type coalescer, makes described antiblocking sectional type coalescer inside be full of remained ammonia.
Described clear remained ammonia groove has centre exit and bottom, and the distance of this centre exit and bottom accounts for 1/4 ~ 2/5 of described clear remained ammonia groove height.
The inside of described antiblocking sectional type coalescer is filled with one-level filler and secondary filler two sections of fillers respectively.
Described one-level filler is stacking after being bent by multilayer surface treated stainless steel substrates ripple to be formed and surfaces hydrophilic.
Described secondary filler is wound around mutually braiding by Stainless Steel Wire and organic fibrous material and forms and surface oleophilic, and knitting tightness is 0.90 ~ 0.97.
Have gap between described secondary filler and described antiblocking sectional type coalescer inwall, the width in described gap is determined according to impurity size, prevents the impurity in remained ammonia from making system jams.
The invention has the beneficial effects as follows: have employed antiblocking sectional type coalescer, achieve the quick tar removing of remained ammonia.In a link, multiple-stage treatment is carried out to remained ammonia, reached splendid deoiling effect, shortened the length of pipeline of whole system.Adopt the method both can not increase the man-hour of Production Flow Chart to remained ammonia oil removing, production technique also can not be caused to become very complicated, and achieve again ammoniacal liquor and burnt oil separating efficiently, significantly reduce the tar content in remained ammonia.In addition, apparatus structure of the present invention is simple, stable, easy to maintenance, oil removal efficiency is high and do not need to do to existing pipeline the series of advantages significantly transformed.
