Abstract
Finished product storage device is refine to phthalic anhydride comprises big jar of finished product pans, middle pump, finished product phthalic anhydride and finished product pump, and the finished product pans link to each other with middle pump, and middle delivery side of pump links to each other for big jar with the finished product phthalic anhydride, and the finished product phthalic anhydride links to each other through finished product pump and knot piece workshop phthalic anhydride head tank for big jar, advances to set up direct valve between the pipeline of the big jar of finished product phthalic anhydride and the pipeline that finished product pump advances to tie piece workshop phthalic anhydride head tank at middle pump. The utility model discloses a set up direct valve between the pipeline of big jar of finished product phthalic anhydride and knot piece workshop phthalic anhydride head tank to realize the direct knot piece process that gets into of qualified phthalic anhydride product, regarded as the buffer tank to use in the big jar of finished product phthalic anhydride, reduced operating power consumption, had simple structure, convenient to use and energy saving and consumption reduction's advantage.
Description
Technical field
This utility model is related to phthalic anhydride production and processing engineering device technique field and in particular to a kind of phthalic anhydride refines finished product storage dress
Put.
Background technology
Phthalic anhydride also known as phthalic anhydride, phthalic anhydride is now widely used for chemical industry, medicine, electronics, agricultural, coating, fine
The industrial departments such as chemical industry.Phthalic anhydride plant at present, after synthesis purification, phthalic anhydride finished product can be first stored in the middle of finished product phthalic anhydride
In tank, qualified through chemically examining, the phthalic anhydride raw material then delivering to subsequent processing sheeting workshop in the big tank of finished product phthalic anhydride again delivered to again by phthalic anhydride
In tank, this phthalic anhydride refines finished product storage device and there is following drawback：Qualified phthalic anhydride finished product Stored Procedure is more, needs through excessive
Secondary pump just can be delivered in the phthalic anhydride head tank in sheeting workshop, lead to operation energy consumption high, be unfavorable for the cost control of phthalic anhydride product.
Utility model content
This utility model provides a kind of phthalic anhydride and refines finished product storage device, to solve the qualified phthalic anhydride of prior art presence
The more problem leading to high energy consumption of finished product Stored Procedure.
This utility model solves its technical problem and be employed technical scheme comprise that：
A kind of phthalic anhydride refines finished product storage device, by finished product pans, line pump, the big tank of finished product phthalic anhydride and finished product pump group
Become, finished product pans are connected with line pump, and the outlet of line pump tank big with finished product phthalic anhydride is connected, the big tank of finished product phthalic anhydride passes through finished product
Pump is connected with sheeting workshop phthalic anhydride head tank, enters the pipeline of the big tank of finished product phthalic anhydride in line pump and discharge pump enters sheeting workshop phthalic anhydride
Direct-through valve is set between the pipeline of head tank.
The operation principle of this utility model device：In normal production, the phthalic anhydride of finished product pans is qualified through chemically examining, permissible
Directly pump in the phthalic anhydride head tank of sheeting workshop by line pump through direct-through valve, the big tank of finished product phthalic anhydride is only in sheeting workshop not just
It is used for intermediate storage when often, use as buffering.
This utility model passes through to arrange straight-through valve between the pipeline of the big tank of finished product phthalic anhydride and sheeting workshop phthalic anhydride head tank
Door, it is achieved thereby that qualified phthalic anhydride product is directly entered sheeting operation, big for finished product phthalic anhydride tank is used as surge tank, reduces
Operation energy consumption, has the advantages that structure is simple, easy to use and energy-saving.
Brief description
With reference to the accompanying drawings and examples this utility model is further illustrated.
Fig. 1 is the structural representation of this utility model device.
In figure 1 finished product pans, 2 line pumps, the big tank of 3 finished product phthalic anhydrides, 4 discharge pumps, 5 sheeting workshop phthalic anhydride head tanks, 6 straight
Port valve door.
Specific embodiment
As shown in the figure：A kind of phthalic anhydride refines finished product storage device, by finished product pans 1, line pump 2, the big tank of finished product phthalic anhydride 3
Form with discharge pump 4, finished product pans 1 are connected with line pump 2, the outlet of line pump 2 tank 3 big with finished product phthalic anhydride is connected, finished product
The big tank of phthalic anhydride 3 is connected with sheeting workshop phthalic anhydride head tank 5 by discharge pump 4, enters the pipeline of the big tank of finished product phthalic anhydride 3 in line pump 2
And discharge pump 4 enters to arrange direct-through valve 6 between the pipeline of sheeting workshop phthalic anhydride head tank 5.
The operation principle of this utility model device：In normal production, the phthalic anhydride of finished product pans is qualified through chemically examining, permissible
Directly pump in the phthalic anhydride head tank of sheeting workshop by line pump through direct-through valve, the big tank of finished product phthalic anhydride is only in sheeting workshop not just
It is used for intermediate storage when often, use as buffering.
