Abstract

The utility model discloses a heavy turpentine batch distillation device with a vacuum residue discharging system. The heavy turpentine batch distillation device comprises a distillation still, wherein a residue discharging hole is formed in the distillation still. The heavy turpentine batch distillation device is characterized in that the vacuum residue discharging system is connected onto the residue discharging hole and comprises a residue discharging kettle and a vacuum buffer tank, the residue discharging kettle is connected with the residue discharging hole by a pipeline, the vacuum buffer tank is connected with the residue discharging kettle by a pipeline, and a vacuum pump is connected onto the vacuum buffer tank by a pipeline. According to the heavy turpentine batch distillation device with the vacuum residue discharging system, the vacuum residue discharging system is connected onto the residue discharging hole of the distillation still, and by virtue of the difference of vacuum degrees of the distillation still and the residue discharging kettle, the vacuum degree of the distillation still is artificially controlled to be lower than that of the residue discharging kettle when residues are discharged, and then the distillation residues are pressed into the residue discharging kettle. The heavy turpentine batch distillation device has the advantages of having a simple structure, shortening the production period, improving the production efficiency and the like.

Description

A kind of heavy turpentine batch distillation device with vacuum dreg removing system

Technical field

It is this that the utility model relates to turpentine oil production, particularly a kind of heavy turpentine batch distillation device with vacuum dreg removing system.

Background technology

The general employing of residue of existing heavy turpentine batch distillation sheds the vacuum of distillation still completely, then under the effect of gravity, discharge residue, its shortcoming is: the speed of deslagging is slow, affect the charging process again of batch distillation column, and when distilling new a collection of product again, distillation still to again from normal pressure, vacuumize waste production time, increase production cost.

Summary of the invention

For the problems referred to above, it is a kind of simple in structure that the purpose of this utility model is to provide, a kind of heavy turpentine batch distillation device with vacuum dreg removing system that shortens the production cycle and enhance productivity.

For achieving the above object, the technical scheme that the utility model proposes is: a kind of heavy turpentine batch distillation device with vacuum dreg removing system, comprise distillation still, in described distillation still, there is a slag-drip opening, it is characterized in that: on described slag-drip opening, be connected with a vacuum dreg removing system, described vacuum dreg removing system comprises deslagging still, vacuum buffer tank, described deslagging still is connected with slag-drip opening by pipeline, described vacuum buffer tank connects deslagging still by pipeline, on described vacuum buffer tank, is connected with a vavuum pump by pipeline.

Preferably, on the pipeline between described deslagging still and vacuum buffer tank, be also provided with condenser, make the temperature of vacuum buffer tank can be not too high, and then affect the efficiency that vacuumizes of vavuum pump.

Adopt technique scheme, heavy turpentine batch distillation device with vacuum dreg removing system described in the utility model, by be connected with a vacuum dreg removing system on the slag-drip opening of distillation still, utilize the vacuum poor (being draught head) of distillation still and deslagging still, when deslagging, manual control distillation still vacuum, than deslagging still low (it is high that low vacuum is air pressure), extrudes bottoms to deslagging still, have simple in structurely, shorten production cycle and the advantage such as enhance productivity.

Brief description of the drawings

Fig. 1 is the heavy turpentine batch distillation apparatus structure schematic diagram with vacuum dreg removing system described in the utility model;

Wherein: 1. distillation still, 2. slag-drip opening, 3. deslagging still, 4. vacuum buffer tank, 5. condenser, 6. vavuum pump.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described further.

As shown in Figure 1, a kind of heavy turpentine batch distillation device with vacuum dreg removing system, comprise distillation still 1, in described distillation still 1, there is a slag-drip opening 2, on slag-drip opening 2, be connected with a vacuum dreg removing system, vacuum dreg removing system comprises deslagging still 3, vacuum buffer tank 4, described deslagging still 3 is connected with slag-drip opening 2 by pipeline, described vacuum buffer tank 4 connects deslagging still 3 by pipeline, on described vacuum buffer tank 4, be connected with a vavuum pump 6 by pipeline, can on the pipeline between deslagging still 3 and vacuum buffer tank 4, also be provided with condenser 5 in addition, make the temperature of vacuum buffer tank 4 can be not too high, and then can not affect the efficiency that vacuumizes of vavuum pump 6.

When concrete use, in the time of needs deslagging, open vavuum pump, in the time that deslagging still vacuum meter shows " 0.09MPa ", close vavuum pump valve and vavuum pump → open distillation still drain valve → still vacuum meter to be distilled while showing " 0.08MPa ", close emptying valve → open distillation still slag-drip opening → in the time that deslagging still vacuum meter air pressure is consistent with destilling tower vacuum meter air pressure, after closing distillation still slag-discharging valve → distillation still the charging of charging → distillation still completing again, slowly open deslagging still drain → in the time that deslagging still air pressure is consistent with atmospheric pressure (deslagging still vacuum meter shows that air pressure is 0MPa), open deslagging still slag-discharging valve, emit residue.

Although specifically show and introduced the utility model in conjunction with preferred embodiment; but those skilled in the art should be understood that; not departing from the spirit and scope of the present utility model that appended claims limits; in the form and details the utility model is made a variety of changes, be protection domain of the present utility model.
