Abstract
The utility model relates to a rectification device, which comprises a rectification tower (1) and a reboiler (2), wherein a liquid phase end (3) and a gas phase end (4) of the rectification tower are respectively connected to two ends of the reboiler (2) through connecting pipes. The rectification device is characterized in that a forced circulation pump (5) is serially connected onto a connecting pipe arranged between the liquid phase end (3) and the reboiler (2). For materials with high content and high viscosity, the pump is utilized for improving the heat exchange efficiency of the materials, so the better mass transfer effect is obtained.
Description
Technical field
The utility model relates to a kind of rectifier unit, mainly comprises rectifying column and reboiler.
Background technology
Material rectifying often is used in combination reboiler and rectifying column in producing.Reboiler is serially connected between the liquid phase end and gas phase end of rectifying column, utilizes the liquid level equilibrium principle to keep material liquid level in the reboiler and fractionating column liquid level at sustained height.Reboiler provides liquid phase to enter into reboiler as heat-exchange device at the bottom of rectifying tower, and to the material vaporization that heats up, the material that is vaporized is sent back in the rectifying column, return gaseous phase materials in the tower upwards by tower tray, and liquid phase material falls to get back at the bottom of the tower.Because the effect of differential static pressure will constantly replenish the part liquid level that is evaporated at the bottom of the tower.But the large and high material of viscosity will produce the bad problem of material mass transfer effect that causes not because of evaporation capacity for content.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of rectifier unit, has the good characteristics of material mass transfer effect.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of rectifier unit, comprise rectifying column and reboiler, liquid phase end and the gas phase end of described rectifying column are connected to the reboiler two ends by tube connector respectively, and its innovative point is: be serially connected with forced circulation pump on the tube connector between described liquid phase end and the reboiler.
The utility model has the advantage of: the tube connector between rectifying column liquid phase end and reboiler arranges forced circulation pump, utilize the characteristics that the forced circulation pump pump pressure is high and liquid is difficult for stopping in the pump housing, accelerate the cycle heat exchange frequency of liquid phase material, thereby improve the mass transfer effect of material.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is done further detailed description.
Shown in Figure 1 is the structural representation of the utility model rectifier unit.
The specific embodiment
Rectifier unit shown in Figure 1 comprises rectifying column 1 and reboiler 2, the liquid phase end 3 of described rectifying column and gas phase end 4 are connected to reboiler 2 two ends by tube connector respectively, large and the high material of viscosity for content, for strengthening evaporation capacity, be connected in series forced circulation pump 5 at described liquid phase end 3 with tube connector between the reboiler 2, utilize pump to strengthen the heat exchange frequency of material, thereby obtain good mass transfer effect.
