Abstract
The utility model discloses a toluene distillation separation device which comprises a rectifying tower (1), a condenser (2) and a gas-liquid separator (3), wherein the condenser (2) is arranged above the gas-liquid separator (3), the top of the rectifying tower (1) is communicated with the upper portion of the gas-liquid separator (3),a liquid phase connector (3a) in the middle of the gas-liquid separator and the rectifying tower (1) are communicated to form external backflow, and a liquid phase connector (3b) in the bottom of the gas-liquid separator (3) is communicated with a water separating device (4) through pipelines. The toluene distillation separation device is simple and reasonable in structure and high in separating efficiency during toluene separation.
Description
Technical field
The utility model belongs to the chemical plant installations field, relates in particular to a kind of toluene distillation separator.
Background technology
The distillation principle is utilized the difference of each component volatilization degree in liquid mixture, liquid mixture is partly vaporized and make the vapor portion condensation thereupon, thereby realizing the separation of its contained component, is widely used in the separating-purifying in chemical industry.Adopt the distillation principle to carry out separating-purifying and just need a cover separated device.When separation of methylbenzene, the distillation mode of the interior backflow that traditional separated device adopts, so-called interior reflux type is exactly namely that condenser is built-in, directly condenser is arranged on the top of rectifying column; But can bring a problem, the azeotropic gas of some toluene and water directly is back to the reduction that causes distillation efficiency in rectifying column downwards after meeting condenser.
Summary of the invention
Content of the present utility model is the shortcoming that overcomes prior art, separates the high a kind of separated device of efficient when a kind of piptonychia benzene is provided.
For solving the problems of the technologies described above, concrete technical scheme of the present utility model is as follows:
A kind of toluene distillation separator comprises rectifying column and condenser, it is characterized in that: comprise that also one can divide the gas-liquid separator of water, described condenser is arranged on the top of Gas and liquid flow diverter, and described rectifying column top is connected with gas-liquid separator top by pipeline; The formation exteenal reflux that is connected with rectifying column of described Gas and liquid flow diverter middle part liquid phase interface; The liquid-phase outlet of described Gas and liquid flow diverter bottom is connected with division box by pipeline.
The utility model is simple and reasonable, can efficiently toluene distillation be separated, and has higher practicality.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, the utility model comprises rectifying column 1, is connected by the top of pipeline with gas-liquid separator 3 at rectifying column 1 top, and a condenser 2 is set at the top of gas-liquid separator 3.The described gas-liquid separator middle part liquid phase interface 3a formation exteenal reflux that is connected with rectifying column 1; Gas-liquid separator 3 bottoms arrange a division box 4 carry out toluene and standing separation, division box 4 is connected with the liquid-phase outlet 3b of gas-liquid separator by pipeline.During rectifying, in rectifying column 1, the mist of toluene and water rises in gas-liquid separator 3, and after condenser 2 was cooling, downward liquid flow was put in division box 4 through the liquid-phase outlet 3b of gas-liquid separator stream; Condensate liquid is back to circulation distillation in rectifying column 1 by gas-liquid separator middle part liquid phase interface 3a after minute water.Division box 4 can be separated water and toluene, has just completed the disengaging of toluene.
The utility model is simple and reasonable, has higher separated efficient during separation of methylbenzene, has greatly improved productivity ratio.
