Abstract
The utility model provides oil-enriched negative-pressure debenzoilized light benzene condensing and cooling backflow equipment, comprising a horizontal tank body and a light benzene condensing and cooling device. The middle position of the bottom of the horizontal tank body is communicated with the top of a vertical tank body; a light benzene outflow opening is arranged at the bottom of the horizontal tank body; a separated water outflow opening is arranged at the bottom of the vertical tank body; the horizontal tank body is communicated with the light benzene condensing and cooling device through a refrigerant access tube and a pressure balance tube; and the top of the vertical tank body is connected with the vacuum pump through a negative-pressure tube. According to the oil-enriched negative-pressure debenzoilized light benzene condensing and cooling backflow equipment provided by the utility model, the oil-enriched debenzoilization and distillation process is designed from constant pressure operation to negative pressure operation, and negative pressure is good for reducing a distillation boiling point of light benzene at the top of a tower, so the load of the light benzene condensing and cooling device is reduced; and the energy is saved and the consumption is reduced. The negative-pressure distillation does not use steam, the separated water amount of light benzene is less and only the water content in enriched oil needs to be separated, so that the separated water in the light benzene is separated without adopting a plurality of backflow column equipment, and the cost of the equipment is reduced.
Description
Technical field
The utility model relates to Coal Chemical Industry rich oil crude benzol distillation equipment, specifically a kind of light benzene condensation cooling for reflux equipment of rich oil negative pressure benzene removal.
Background technology
Existing rich oil de-benzene process is to take off benzene through the vapor distillation method normal pressure.Crude benzol steam recovered (distilled) temperature is high during air-distillation, and the energy consumption of equipment is also high.Owing to utilize steamed to blow, cause the branch in the crude benzol dried up more, so need the branch in a plurality of equipment combined treatment crude benzol of design dried up, the equipment self cost is higher.
The utility model content
The purpose of the utility model provides a kind of light benzene condensation cooling for reflux equipment of rich oil negative pressure benzene removal; It is designed to negative-pressure operation with the rich oil de-benzene distil process by normal pressure; Negative pressure helps reducing the boiling point that distillates of cat head light benzene, has alleviated the load of light benzene condensate cooler, and is energy-saving and cost-reducing.Vacuum distillation does not utilize steam, and it is less that light benzene separates the water yield, moisture in the rich oil, thus need not adopt the branch in a plurality of reflux column device separates light benzenes dried up, reduced the cost of equipment self.
The utility model is for realizing above-mentioned purpose; Realize through following technical scheme: comprise horizontal tank body and light benzene condensate cooler; Horizontal tank base centre position is communicated with the top of vertical tank body, and horizontal tank base is provided with the light benzene flow export, and vertical tank base is provided with the separated flow outlet; Be communicated with through cooling fluid access tube and pressure-equalizing pipe between horizontal tank body and the light benzene condensate cooler, vertical tank body top is connected with vavuum pump through the negative pressure pipe.Horizontal inner tank wall is provided with the annular brace muscle.Through hole is offered in annular brace muscle bottom.On the horizontal inner tank wall at light benzene flow export place vortex shield is set.
The advantage of the utility model is: the rich oil de-benzene distil process is designed to negative-pressure operation by normal pressure, and negative pressure helps reducing the boiling point that distillates of cat head light benzene, has alleviated the load of light benzene condensate cooler, and is energy-saving and cost-reducing.Vacuum distillation does not utilize steam, and it is less that light benzene separates the water yield, moisture in the rich oil, thus need not adopt the branch in a plurality of reflux column device separates light benzenes dried up, reduced the cost of equipment self, service life of equipment is long, and the light benzene resistance to outflow is little etc.

Fig. 1 is the utility model structural representation.
The specific embodiment
The light benzene condensation cooling for reflux equipment of the described a kind of rich oil negative pressure benzene removal of the utility model; Comprise horizontal tank body 1 and light benzene condensate cooler 2; Centre position, horizontal tank body 1 bottom is communicated with the top of vertical tank body 11, and horizontal tank body 1 bottom is provided with light benzene flow export 3, and vertical tank body 11 bottoms are provided with separated flow outlet 4; Is communicated with through cooling fluid access tube 5 and pressure-equalizing pipe 6 between horizontal tank body 1 and the light benzene condensate cooler 2, vertical tank body 1 top is passed through negative pressure pipe 7 and is connected with vavuum pump 8.The utility model is designed to negative-pressure operation with the rich oil de-benzene distil process by normal pressure, and negative pressure helps reducing the boiling point that distillates of cat head light benzene, has alleviated the load of light benzene condensate cooler, and is energy-saving and cost-reducing.Vacuum distillation does not utilize steam, and it is less that light benzene separates the water yield, moisture in the rich oil, thus need not adopt the branch in a plurality of reflux column device separates light benzenes dried up, reduced the cost of equipment self.Pressure-equalizing pipe 6 is used for the pressure between horizontal tank body 1 of balance and the light benzene condensate cooler 2.
Interior notch distortion can be provided with annular brace muscle 9 at horizontal tank body 1 inwall to the utility model in order to prevent horizontal tank body 1 to receive suction function for a long time.Annular brace muscle 9 can effectively increase the intensity of horizontal tank body 1, prevents that horizontal tank body 1 from caving in, and helps prolonging the service life of equipment.
The utility model can all flow out in order to guarantee the light benzene in the horizontal tank body 1, can offer through hole 10 in annular brace muscle 9 bottoms.
The utility model causes the light benzene resistance to outflow to increase for the liquid that prevents light benzene flow export 3 places forms eddy current, can on horizontal tank body 1 inwall at light benzene flow export 3 places, vortex shield 13 be set.12 is debenzolizing towers among the figure.
