Description
Technical field
The utility model relates to a kind of chemical industry equipment, especially a kind of efficient tail gas recycle tank.
Background technology
In each process procedure of Chemical Manufacture; often can use multi-solvents; chemical industry operation also be unable to do without distillation unit; distillation unit is to utilize each component boiling point difference in mixing material or liquid-solid system; make low boiling component evaporation; condensation, to separate the unit process of whole component, is the associating of evaporation and two kinds of unit operations of condensation again.Distillation process by distill that unit produces can not total condensation through condenser under tail gas in contain solvent, tail gas both can produce and pollute environment, increase again solvent consumption, thereby increases production cost.So conventionally connect tail gas absorption tank by pipeline after the condenser of distilling apparatus, make the further condensation of tail gas by cooling in tail gas absorption tank, fully to reclaim solvent.The structure of common tail gas absorption tank comprises tank body, and tank body is provided with chuck, passes into chilled brine in chuck, carries out solvent recovery.The problem existing is: because the film-cooled heat of chuck is certain and less than normal, have influence on the cooling effectiveness of tail gas, still can cause the partial solvent can not be completely cooling.If adopt the multiple tail gas absorption tanks of increase to carry out the method for tail gas multi-stage condensing, have again the production site of taking large, the problem that equipment investment is high.
Utility model content
The purpose of this utility model is the drawback for prior art, provides a kind of cooling device of setting up in tail gas recycle tank to improve the efficient tail gas recycle tank of condensation efficiency.
Problem described in the utility model is by realizing with following technical proposals:
A kind of efficient tail gas recycle tank, it comprises tank body, tank body is provided with cooling jacket, special feature is: in described tank body, be provided with cooling coil, cooling coil is in the shape of a spiral around setting, cooling coil two ends are provided with cooling coil salt water inlet and cooling coil brine outlet, and cooling coil salt water inlet and cooling coil brine outlet are passed by tank body both sides respectively, are arranged on tank body top.
Above-mentioned efficient tail gas recycle tank, the axis of described cooling coil and the dead in line of tank body, the 1.8-2.2 of the spiral surrounding outside diameter d that described tank body inner diameter D is cooling coil is doubly.
Above-mentioned efficient tail gas recycle tank, in described tank body, be provided with two upper spacers and a lower clapboard, lower clapboard is between two upper spacers, and each dividing plate is semicircle, the semicircle periphery of upper spacer is connected with tank body upper inside wall, and the semicircle periphery of lower clapboard is connected with tank body lower part inwall.
Above-mentioned efficient tail gas recycle tank, the tube pitch L of described cooling coil is 1.5-2.5 centimetre.
The utility model, for solving existing tail gas recycle tank film-cooled heat deficiency, causes the inadequate problem of tail gas recycle to be improved, and has designed a kind of efficient tail gas recycle tank.The tank wall of described efficient tail gas recycle tank is provided with the cooling jacket that can pass into chilled brine, be provided with the cooling coil of arranging in the shape of a spiral in tank interior, in cooling coil, pass into chilled brine, enter the tail gas of recycling can under the dual-cooled effect of cooling jacket and cooling coil, be able to abundant condensation.The utility model, by set up cooling coil in tail gas recycle tank, has increased considerably tail gas recycle tank film-cooled heat, and the solvent in tail gas is fully reclaimed, and is conducive to reduce environmental pollution and enterprise's production cost.In addition, the utility model compact conformation, fitting operation are flexible, leave suitable gap between cooling coil and tank body, can remove in time the solids such as icing, dirt, avoid blocking pipe.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure, each list of reference numerals is: 1, cooling coil, 2, cooling jacket, 3, cooling coil salt water inlet, 4, exhaust outlet, 5, upper spacer, 6, air inlet, 7, cooling jacket brine outlet, 8, cooling coil brine outlet, 9, tank body, 10, manhole, 11, sewage draining exit, 12, lower clapboard, 13, cooling jacket salt water inlet, 14, take out material mouthful.
Detailed description of the invention
Referring to Fig. 1, the utility model comprises tank body 9, and tank body is provided with cooling jacket 2, passes into chilled brine in cooling jacket, and cooling jacket salt water inlet 13 is arranged on tank body lower part, and cooling jacket brine outlet 7 is arranged on tank body top.The left and right sides of tank body lower part is respectively equipped with takes out material mouth 14 and sewage draining exit 11, and tank body two ends are provided with manhole 10, and tank body top is provided with exhaust outlet 4 and air inlet 6.
Still referring to Fig. 1, in order to increase the film-cooled heat of tail gas recycle tank, thereby improve the cooling effect of tail gas recycle tank, the utility model has been set up cooling coil 1 in tank body, cooling coil is in the shape of a spiral around setting, cooling coil two ends are provided with cooling coil salt water inlet 3 and cooling coil brine outlet 8, and cooling coil salt water inlet 3 and cooling coil brine outlet 8 are passed by tank body both sides respectively, are arranged on tank body top.For making the tail gas in tank body evenly cooling, the dead in line of the axis of cooling coil 1 and tank body 9; For ease of removing the solids such as freezing in tank body, dirt, between cooling coil and tank body, leave suitable gap, doubly, the tube pitch L of cooling coil is 1.5-2.5 centimetre to the 1.8-2.2 of the spiral surrounding outside diameter d that tank body inner diameter D is cooling coil.
