Abstract

The invention discloses a kind of pet reaction equipment, comprise reactor, the top of described reactor is erect and is connected with vertical filled column, described vertical filled column top is erect and is connected to vertical (type) condenser, the top droop of described vertical (type) condenser is down connected with horizontal condenser, described horizontal condenser be connected with water knockout drum bottom, described water knockout drum is connected with return duct, the highest point of described return duct connects described water knockout drum, the lowest part of described return duct connects described reactor, described return duct is in series with a backflow compensator, described backflow compensator is flexible perfluoroelastomers backflow compensator.The present invention compared with prior art, can existing pet reaction device fabrication time inside easily produce negative pressure, use inconvenience, affect the problem of production efficiency.

Description

Pet reaction equipment
Technical field
The present invention relates to resin deep process technology field, especially a kind of equipment for pet reaction.
Background technology
At present, the pet reaction equipment that existing resin deep processing enterprise uses, generally comprise reactor, the top of reactor is erect and is connected with vertical filled column, vertical filled column top is erect and is connected to vertical (type) condenser, and the top droop of vertical (type) condenser is down connected with horizontal condenser, horizontal condenser be connected with water knockout drum bottom, water knockout drum is connected with return duct, the lowest part coupled reaction still of return duct.Like this when reacting, when the cut that condensation is got off is back to reactor, because temperature declines, and all inner opposing seal of whole equipment, thus easily produce negative pressure, cut is refluxed not smooth, affect production efficiency, and the long-term service life that so also can affect equipment, if add air easily produce pollution to cut.
Summary of the invention
Problem to be solved by this invention is to provide a kind of pet reaction equipment, and during to solve existing pet reaction device fabrication, inside easily produces negative pressure, uses inconvenience, affects the problem of production efficiency.
In order to solve the problem, the technical solution used in the present invention is: this pet reaction equipment comprises reactor, the top of described reactor is erect and is connected with vertical filled column, described vertical filled column top is erect and is connected to vertical (type) condenser, the top droop of described vertical (type) condenser is down connected with horizontal condenser, described horizontal condenser be connected with water knockout drum bottom, described water knockout drum is connected with return duct, the highest point of described return duct connects described water knockout drum, the lowest part of described return duct connects described reactor, described return duct is in series with a backflow compensator, described backflow compensator is flexible perfluoroelastomers backflow compensator.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
This pet reaction equipment adopts on return duct, is in series with a backflow compensator, backflow compensator is flexible perfluoroelastomers backflow compensator, can change and equalizing pressure according to pressure like this, make the cut of backflow can under the pressure of compared with normal, reactor is back to from the water knockout drum of eminence, production efficiency is ensured preferably, does not also affect the service life of equipment simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing enforcement, the invention will be further described:
Pet reaction equipment as shown in Figure 1, it includes reactor 1, the top of reactor 1 is erect and is connected with vertical filled column 2, vertical filled column 2 top is erect and is connected to vertical (type) condenser 3, the top of vertical (type) condenser 3 is connected with horizontal condenser 4 inclined downward by pipe joint, horizontal condenser 4 be connected with water knockout drum 5 bottom, water knockout drum 5 is connected with return duct 6, the highest point of return duct 6 connects water knockout drum 6, the lowest part coupled reaction still 1 of return duct 6.Return duct 6 is in series with a backflow compensator 7, this backflow compensator 7 is flexible perfluoroelastomers backflow compensator.Flexible perfluoroelastomers backflow compensator can change and dilation according to the pressure in return duct 6, pressure balance to a certain extent in maintenance equipment, make the cut of backflow can under the pressure of compared with normal, reactor 1 is back to from the water knockout drum 5 of eminence, production efficiency is ensured preferably, does not also affect the service life of equipment simultaneously.
