Abstract
The utility model discloses a kind of filter-press blowback device of air reducing product PT acid, belong to purger technical field.Include the blowback gas pipeline being connect with filter-press, the blowback gas pipeline connects wind turbine, and nitrogen purge line connects the blowback gas pipeline through heat exchanger, and the nitrogen purge line between the heat exchanger and blowback gas pipeline is equipped with control valve a.The utility model has the beneficial effects that：Increase one pure nitrogen gas blow line in the existing blowback gas pipelines of RPF, and heating transformation is carried out to the pure nitrogen gas for entering RPF, pure nitrogen gas is increased to 160 DEG C by room temperature by heat exchanger, enter back into RPF blow lines, nitrogen, vapor ratio effectively in adjusting filter-press system, effective help is played to control product PT acid.
Description
Technical field
The utility model is related to a kind of filter-press blowback air systems, belong to purger technical field.
Background technology
In the prior art, filter-press blowback air is to be directly entered filter-press after boosting by circulating fan
(RPF), exceeded, sour (p-methylbenzoic acid) nothings of PT of product are fluctuated frequent occurrence in actual moving process drying machine product PT acid
Method controls.
Utility model content
To solve defect of the existing technology, the purpose of this utility model is to provide a kind of to the effectively control of product PT acid
Reduction product PT acid filter-press blowback device of air.
The technical solution of the utility model is：A kind of filter-press blowback device of air reducing product PT acid, including with
The blowback gas pipeline of filter-press connection, the blowback gas pipeline connect wind turbine, and nitrogen purge line connects institute through heat exchanger
Blowback gas pipeline is stated, the nitrogen purge line between the heat exchanger and blowback gas pipeline is equipped with control valve a.
The blowback gas pipeline is equipped with control valve b and butterfly valve.
The interface of the nitrogen purge line and blowback gas pipeline is between control valve b and filter-press.
The nitrogen purge line is pure nitrogen gas blow line.
Nitrogen is warming up to 160 DEG C after heat exchanger heat exchange.
Blowback medium in the blowback gas pipeline is vapor.
The utility model has the beneficial effects that：Increase one pure nitrogen gas blow line in the existing blowback gas pipelines of RPF, and right
Pure nitrogen gas into RPF carries out heating transformation, and pure nitrogen gas is increased to 160 DEG C by room temperature by heat exchanger, enters back into RPF purgings
Pipeline, nitrogen, vapor ratio effectively in adjusting filter-press system, effective help is played to control product PT acid.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
Reference numeral is as follows in figure：1, filter-press, 2, blowback gas pipeline, 3, nitrogen purge line, 4, heat exchanger, 5,
Control valve a, 6, control valve b, 7, wind turbine, 8, butterfly valve.
Specific implementation mode
1 pair of the utility model is described further below in conjunction with the accompanying drawings：
A kind of filter-press blowback device of air reducing product PT acid, includes the blowback air being connect with filter-press 1
Pipeline 2, the blowback gas pipeline 2 connect wind turbine 7, and nitrogen purge line 3 connects the blowback gas pipeline 2 through heat exchanger 4, described
Nitrogen purge line 3 between heat exchanger 4 and blowback gas pipeline 2 is equipped with control valve a5.
The blowback gas pipeline 2 is equipped with control valve b6 and butterfly valve 8.
The interface of the nitrogen purge line 3 and blowback gas pipeline 2 is between control valve b6 and filter-press 1.
The nitrogen purge line 3 is pure nitrogen gas blow line.
Nitrogen is warming up to 160 DEG C after the heat exchange of the heat exchanger 4.
Blowback medium in the blowback gas pipeline 2 is vapor.
Increase one pure nitrogen gas blow line 3 in the existing blowback gas pipelines of RPF, and the pure nitrogen gas for entering RPF is risen
Temperature transformation, is increased to 160 DEG C by room temperature by pure nitrogen gas by heat exchanger 4, enters back into the blowback gas pipeline 2 of RPF, effectively adjusts pressure
Nitrogen, vapor ratio in 1 system of power filter play effective help to control product PT acid.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change
The scope of protection of the utility model is also should be regarded as into modification.
