Abstract

The utility model discloses a multi-column energy-saving alcohol distillation device, which comprises a crude distillation column, an aldehyde column, a rectifying column and a heat conducting oil boiler. The crude distillation column forms a circulating distillation loop with a plurality of condensers and vacuum air pumps through a pipeline, the top portion of the aldehyde column forms a circulating distillation loop with a plurality of condensers and pumps through an alcohol output pipe, a heater of the rectifying column and a heater of the aldehyde column form a loop with the heat conducting oil boiler through heat conducting input and output pipes, and a flash tank is arranged between the rectifying column and the aldehyde column. Under the environment of pressure-differential distillation, because of the repeated circulation distillations of the crude distillation column, the aldehyde column and the rectifying column, the quality and the purity of the alcohol are greatly improved. The heat conducting oil is used as a heating medium, thereby the heat conduction is speeded up, the heat supply is stable, and the energy consumption is reduced. Further, a float valve is mounted on a veneer sheet of the column, and thereby vapors can be fully given off and are not easy to be blocked by impurity. The flash tank is arranged between the rectifying column and the aldehyde column to recover vapor and the recovered vapor is supplied to the aldehyde column, thereby improving the utilization of the heat energy.

Traditional multitower differential pressure alcohol distillation device is a medium with the water vapour, and it exists not enough, and the water vapour heat radiation is slow, heat supply instability, coal consumption height, phenomenon such as electricity consumption is many.Thereby cause its distillation benefit low, the cost height, its water vapour boiler safety coefficient is low in addition, fouling easily in process of production, and the maintenance that stops production causes economic loss.Labour intensity is big, thereby makes the cost of Alcohol Production enterprise high.Invent a kind of energy-saving distilling tower, adopt the steam distillation instability, the difficult quality of alcohol is up to state standards owing to distill it.

The utility model content

In order to overcome above-mentioned deficiency, the purpose of this utility model be to provide a kind of alcohol is purified high, production efficiency height, the multitower energy-saving distilling tower apparatus of safe and low energy consumption.

For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of multitower energy-saving distilling tower apparatus, include topping still, aldehyde tower, rectifying column and heat conducting oil boiler, the topping still top is connected with the aldehyde tower bottom by the alcohol efferent duct, the rectifying column top is connected with the finished product condenser, the heater of rectifying column top and topping still bottom forms the loop, it is characterized in that: described topping still is through pipeline and a plurality of condenser and vavuum pump formation circulation distillation loop; The aldehyde top of tower is by alcohol efferent duct and a plurality of condenser and pump formation circulation distillation loop; The heater of the heater of rectifying column and aldehyde tower forms the loop by conduction oil input and output pipe and heat conducting oil boiler.

Be provided with between described rectifying column and the aldehyde tower and dodge true jar, aldehyde tower bottom and rectifying column are connected to form circulation distillation loop.The effect of dodging true jar is: recovered steam uses with supply aldehyde tower.

The laminate of described topping still, aldehyde tower, rectifying column body of the tower is provided with float valve.

Described float valve is by becoming the block plate die sinking to strike out the structure of a round panel and three Z-shaped pin, three Z-shaped pin are positioned at the bottom of round panel and are equally spaced along the periphery of round panel, and each Z-shaped pin active buckle is on the laminate of topping still, aldehyde tower, rectifying column body of the tower.Steam promotes float valve and produces bob, and steam distributes from float valve pin limit under float valve hinders.

The beneficial effects of the utility model are: owing to established vavuum pump in circulation distillation loop, historical facts or anecdotes has showed differential distillation, under the environment of differential distillation, and the distillation of circulation repeatedly by topping still, aldehyde tower, rectifying column, thereby the quality and the purity of alcohol have been improved greatly; With the conduction oil is heat medium, and speed and the heat supply of having accelerated heat conduction are stable, have reduced energy consumption; Be provided with between rectifying column and aldehyde tower and dodge true jar, supply with the aldehyde tower with recovered steam and use, utilize wine vapour that the topping still heater is heated, purpose is to improve the utilization rate of heat energy; Because the laminate of topping still, aldehyde tower, rectifying column body of the tower is provided with float valve, compare with more traditional float valve, reduce cost, more can help steam and fully distribute thereby can reduce the sheet material loss, be not subject to impurity again and stop up.
