Abstract
This utility model belongs to phthalic anhydride preparation field, particularly relates to the switching condenser system in a kind of phthalic anhydride preparation process.Described system includes raw phthalic anhydride pans, raw phthalic anhydride spray pump, spray equipment and switch condenser, described raw phthalic anhydride pans are connected by pipeline with raw phthalic anhydride spray pump, described raw phthalic anhydride spray pump is connected by pipeline with spray equipment, and described spray equipment is placed in above described switch condenser.Use such scheme, the most irregular switch condenser can be implemented liquid phthalic anhydride spray, effectively control the impurity and byproduct of reaction being deposited on switch condenser finned tube, improve the condensation efficiency of switch condenser, extend the safe operation cycle of switch condenser.
Description
Technical field
This utility model belongs to phthalic anhydride preparation field, particularly relates to the switching condensed system in a kind of phthalic anhydride preparation process
System.
Background technology
Switching condenser system in phthalic anhydride preparation process is to be joined directly together with switch condenser by phthalic anhydride spray pump now, benzene
After acid anhydride spray pump material out enters switch condenser containing tarry impurity and byproduct of reaction, it is easier to be deposited on wing
On sheet, blocking can be formed, reduce the condensation efficiency of switch condenser, shorten the safe operation cycle of switch condenser；Certain
Iron salt likely spontaneous combustion more than 160 DEG C of a little side reaction products, causes the accident.
Utility model content
This utility model provides a kind of condensation efficiency that can improve switch condenser, extends the safety fortune of switch condenser
The switching condenser system of line period.
Switching condenser system in a kind of phthalic anhydride preparation process, including raw phthalic anhydride pans, raw phthalic anhydride spray pump, spray
Device and switch condenser, described raw phthalic anhydride pans are connected by pipeline with raw phthalic anhydride spray pump, described raw phthalic anhydride spray pump
Being connected by pipeline with spray equipment, described spray equipment is placed in above described switch condenser.
Further, described switch condenser includes the finned tube uniformly arranged.
Further, described spray equipment is the valve with spray head.
Further, described pipeline is venturi conduit.
After using technique scheme, this utility model brings following beneficial effect: use such scheme, can be according to need
Want irregular and switch condenser is implemented liquid phthalic anhydride spray, effectively control be deposited on switch condenser finned tube miscellaneous
Matter and byproduct of reaction, improve the condensation efficiency of switch condenser, extends the safe operation cycle of switch condenser.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, this utility model is further explained explanation.
Switching condenser system in a kind of phthalic anhydride preparation process, as it is shown in figure 1, include raw phthalic anhydride pans 1, raw phthalic anhydride
Spray pump 2, spray equipment 3 and switch condenser 4, described raw phthalic anhydride pans 1 are connected by pipeline with raw phthalic anhydride spray pump 2,
Described raw phthalic anhydride spray pump 2 is connected by pipeline with spray equipment 3, and described spray equipment 3 is placed on described switch condenser 4
Side, described switch condenser 4 includes the finned tube uniformly arranged, and described spray equipment 3 is the valve with spray head.
Use such scheme, the most irregular switch condenser 4 can be implemented liquid phthalic anhydride spray, effectively control
Make the impurity and byproduct of reaction being deposited on switch condenser 4 finned tube, improve the condensation efficiency of switch condenser, prolong
Grow the safe operation cycle of switch condenser.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from this utility model principle, it is also possible to make some improvements and modifications, these improve and
Retouching also should be regarded as protection domain of the present utility model.
