Abstract
The utility model discloses a kind of polystyrene process units installing condenser at vacuum blower entrance additional, it relates to technical field of chemical.Two grades of devolatilizer are connected with the first liquid collecting tank and two grades of devolatilizer condensers respectively, the lower end of two grades of devolatilizer condensers is connected with the first liquid collecting tank, first liquid collecting tank is connected with circulation ethylbenzene collecting tank, the upper end of two grades of devolatilizer condensers is connected with vacuum blower, vacuum blower is connected with the second liquid collecting tank and the first cycle condenser respectively, first cycle condenser is connected with the second cycle condenser and liquid-ring vacuum pump respectively, and the second cycle condenser is connected with liquid-ring vacuum pump.It can overcome the drawback of prior art, and novel in structural design is reasonable, and condenser is installed additional in the devolatilization gas outlet two grades of devolatilizer, and heavy component material condensation is recovered to liquid collecting tank.Heavy component material is effectively removed, and seldom returns to production system；The vacuum blower of two grades of devolatilizer is bled, and load is little, vacuum improves, internal temperature reduces and device fails is less.
Description
Technical field:
This utility model relates to a kind of polystyrene process units installing condenser at vacuum blower entrance additional, belongs to chemical industry
Equipment technical field.
Background technology:
The heavy component devolatilization of two grades of devolatilizer in polystyrene process units is natural cooling removal method at present, does not has
There is condenser.There is following defect in this natural cooling removal method: 1, heavy component devolatilization weak effect, part heavy component material
Production system can be returned to；2, the vacuum blower of two grades of devolatilizer is bled, and load is big, vacuum is low, internal temperature is high and equipment is easy
Break down.3, two grades of devolatilizer heavy component removing workshop section heavy component material is not removed completely.
Utility model content:
For the problems referred to above, the technical problems to be solved in the utility model is to provide one and installs additional cold at vacuum blower entrance
The polystyrene process units of condenser.
This utility model two takes off vacuum blower entrance and adds tube condenser, and it is cold that it comprises 1, two grades of devolatilizer of two grades of devolatilizer
Condenser the 2, first liquid collecting tank 3, circulation ethylbenzene collecting tank 4, vacuum blower the 5, second liquid collecting tank the 6, first cycle condenser 7, second
Cycle condenser 8 and liquid-ring vacuum pump 9, two grades of devolatilizer 1 are connected with the first liquid collecting tank 3 and two grades of devolatilizer condensers 2 respectively,
The lower end of two grades of devolatilizer condensers 2 is connected with the first liquid collecting tank 3, and the first liquid collecting tank 3 is connected with circulation ethylbenzene collecting tank 4, and two
Level devolatilizer condenser 2 upper end be connected with vacuum blower 5, vacuum blower 5 respectively with the second liquid collecting tank 6 and the first circulating condensing
Device 7 connects, and the first cycle condenser 7 is connected with the second cycle condenser 8 and liquid-ring vacuum pump 9 respectively, and the second circulating condensing
Device 8 is connected with liquid-ring vacuum pump 9.
The beneficial effects of the utility model: it can overcome the drawback of prior art, novel in structural design is reasonable, takes off at two grades
Condenser is installed additional in the devolatilization gas outlet waving device, and heavy component material condensation is recovered to liquid collecting tank.Heavy component material obtains effectively
Removing, seldom returns to production system；The vacuum blower of two grades of devolatilizer is bled, and load is little, vacuum improves, internal temperature reduces
And device fails is less.
Accompanying drawing illustrates:
For ease of explanation, this utility model is embodied as and accompanying drawing is described in detail by following.
Fig. 1 is this utility model structural representation.
Detailed description of the invention:
As it is shown in figure 1, this detailed description of the invention is by the following technical solutions: it comprises 1, two grades of devolatilizer of two grades of devolatilizer
Condenser the 2, first liquid collecting tank 3, circulation ethylbenzene collecting tank 4, vacuum blower the 5, second liquid collecting tank the 6, first cycle condenser 7, the
Two cycle condensers 8 and liquid-ring vacuum pump 9, two grades of devolatilizer 1 connect with the first liquid collecting tank 3 and two grades of devolatilizer condensers 2 respectively
Connecing, the lower end of two grades of devolatilizer condensers 2 is connected with the first liquid collecting tank 3, and the first liquid collecting tank 3 is connected with circulation ethylbenzene collecting tank 4,
The upper end of two grades of devolatilizer condensers 2 is connected with vacuum blower 5, and vacuum blower 5 is cold with the second liquid collecting tank 6 and the first circulation respectively
Condenser 7 connects, and the first cycle condenser 7 is connected with the second cycle condenser 8 and liquid-ring vacuum pump 9 respectively, and the second circulation is cold
Condenser 8 is connected with liquid-ring vacuum pump 9.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.One's own profession
Skilled person will appreciate that of industry, this utility model is not restricted to the described embodiments, described in above-described embodiment and description
