Abstract
The invention relates to a bisphenol S product separating system. The system comprises a reaction still, a condenser, a collection tower A and a collection tower B, wherein the reaction still is communicated with the condenser through a delivery pipeline A, the condenser is communicated with the collection tower A through a delivery pipeline B, the delivery pipeline B is communicated with the collection tower B through a delivery pipeline C, a control valve A is arranged on the delivery pipeline B, and a control valve B is arranged at the position, where the delivery pipeline B is communicated with the delivery pipeline C, of the delivery pipeline C; a knockout drum is connected to the portion, between the control valve A and the collection tower A, of the delivery pipeline B in series, the portion, between the knockout drum and the collection tower A, of the delivery pipeline B is communicated with the collection tower through the delivery pipeline D, a control valve C is additionally arranged at the position, close to the knockout drum, of the delivery pipeline B, and a control valve D is additionally arranged at the position, close to the position where the delivery pipeline B is communicated with the delivery pipeline D, of the delivery pipeline D. The system has the advantages that substances in the collection tower A and the collection tower B are purer through two times of separation, so that separating effect is better.
Description
Technical field
The present invention relates to chemical production equipment field, particularly in a kind of bisphenol S product
The separation system of other materials.
Background technology
Bisphenol S has many premium propertiess such as heat-resisting, fast light and anti-oxidant, and can generate salt with alkali reaction, be the important source material of medical macromolecular materials and various engineering plastics.
In process of production, can adulterate in product bisphenol S product a small amount of sym-trimethylbenzene, first alcohol and water, in order to recycle potent agent, needs sym-trimethylbenzene, first alcohol and water to carry out separated and collected.Existing separation system, comprise reactor, condenser, collection tower A and collect tower B, described reactor is connected by transport pipe A with condenser, condenser is connected by transport pipe B with collection tower A, transport pipe B is connected by transport pipe C with collection tower B, and a control valve A is being provided with on the transport pipe B collecting tower A place, be provided with a control valve B near the transport pipe C at transport pipe B and transport pipe C connectivity points place.
But mainly there is following shortcoming in this separation system: collect in sym-trimethylbenzene collected in tower A a small amount of first alcohol and water that can adulterate, and then affect the purity of sym-trimethylbenzene, thus make separating effect not good.
Summary of the invention
The technical problem to be solved in the present invention is to provide one can improve each material purity
And the bisphenol S product separation system of effectively separation can be carried out.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of bisphenol S product separation system, comprise reactor, condenser, collection tower A and collect tower B, described reactor is connected by transport pipe A with condenser, condenser is connected by transport pipe B with collection tower A, transport pipe B is connected by transport pipe C with collection tower B, and a control valve A is being provided with on the transport pipe B collecting tower A place, be provided with a control valve B near the transport pipe C at transport pipe B and transport pipe C connectivity points place; Its innovative point is: at control valve A and a separating tank that the transport pipe B collected between tower A connects, described separating tank is connected by transport pipe D again with collection tower B with the transport pipe B collected between tower A, and a control valve C is set up on the transport pipe B near separating tank place, the transport pipe D at close transport pipe B and transport pipe D connectivity points place sets up a control valve D.
The invention has the advantages that: other materials in bisphenol S product of the present invention
Separation system, after bisphenol S reactor has reacted, containing a small amount of sym-trimethylbenzene, first alcohol and water in reactor, then by twice separation, and then it is purer with the material purity collected in tower B to make to collect tower A, thus makes separating effect better.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the structural representation of bisphenol S product separation system of the present invention.
Embodiment
The following examples can make the present invention of professional and technical personnel's comprehend, but therefore do not limit the present invention among described scope of embodiments.
The bisphenol S product separation system of the present embodiment, forms primarily of with lower part: reactor 1, condenser 2, collection tower 3, collection tower 4 and separating tank 5.
As shown in Figure 1, reactor 1 is connected by transport pipe 6 with condenser 2, condenser 2 is connected by transport pipe 7 with collection tower 3, transport pipe 7 is connected by transport pipe 8 with collection tower 4, and a control valve 10 is being provided with on the transport pipe 7 collecting tower 3 place, be provided with a control valve 11 near transport pipe 7 and the transport pipe 8 at transport pipe 8 connectivity points place.
At control valve 10 and a separating tank 5 that the transport pipe 7 collected between tower 3 is connected, separating tank 5 is connected by transport pipe 9 again with collection tower 4 with the transport pipe 7 collected between tower 3, and a control valve 12 is set up on the transport pipe 7 near separating tank 5 place, on transport pipe 7 with the transport pipe 9 at transport pipe 9 connectivity points place, set up a control valve 13.
The working process of the bisphenol S product separation system of the present embodiment is as follows: transport pipe 6 is delivered to condenser 2 and cools, open control valve 12 again and cooled sym-trimethylbenzene is delivered to separating tank 5, after sym-trimethylbenzene has been carried, closed control valve 12, open control valve 11 again, cooled first alcohol and water is delivered to by transport pipe 8 and collects tower 4; The first alcohol and water that the sym-trimethylbenzene being delivered to separating tank 5 also can adulterate a small amount of, then open control valve 10 and sym-trimethylbenzene is delivered to collection tower 3, after sym-trimethylbenzene has been carried, closed control valve 10, open control valve 13 again, the first alcohol and water contained is delivered to by transport pipe 9 collects tower 4 in separating tank.
The present embodiment is by twice separation, and then it is purer with the material purity collected in tower B to make to collect tower A, thus makes separating effect better.
The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
