Background technique
R2R device recycles the BA and catalyst in PTA device residue, and the filter of extraction filter contains admittedly in production process
The largely carboxylic acid containing phenyl ring (predominantly IPA M-phthalic acid) can be used for glue industry, the raw material of coating industry or filling
Agent.Extraction filter filters solid process:
It filters solid direct alkali soluble and is discharged into sewerage, filter in solid there are the cobalt-manganese catalyst of economic value and containing benzene
The organic acid of ring.This filter enters sewerage admittedly, and the COD for not only increasing sewage workshop handles load, while a large amount of valuable
Substance discharge waste.
Summary of the invention
To solve the above-mentioned problems, the present invention provides the system of a kind of BA recycled in PTA residue and catalyst, will be valuable
The substance (carboxylic acid, catalyst containing phenyl ring) of value, which sufficiently reappears, to be extracted, and is turned waste into wealth.
The invention is realized by the following technical scheme:
The present invention provides the system of a kind of BA recycled in PTA residue and catalyst, connects using R2R device, including successively
Extractor, extraction filter, decanter, the water phase tank of enriched catalytic agent, the catalyst filter, catalyst recycling can connect, also
It is beaten tank admittedly including filter, the filter filter that mashing tank is used to accept in extraction filter admittedly is solid, and the filter connects mashing tank top admittedly
Extractor is connect, mashing pot bottom connects filter press or cloth envelop collector admittedly for the filter；The filter press or cloth envelop collector
The water phase tank of middle filtrate conduit connection enriched catalytic agent, the filter press or cloth envelop collector, which are equipped with, filters solid discharge line.
Further, in the above-mentioned technical solutions, mashing pot bottom passes through pump connection filter press or cloth bag admittedly for the filter
Filter.It is operated using filter press, the smooth blanking of filter cake and filter cake moisture content is low.
Further, in the above-mentioned technical solutions, the decanter is sequentially connected the oily phase tank of enrichment benzoic acid, rectifying mentions
Take benzoic acid device.
Further, in the above-mentioned technical solutions, described to filter solid discharge line connection IPA packaging system.
Further, in the above-mentioned technical solutions, the water phase tank of the enriched catalytic agent connects sodium carbonate storage tank.It extracted
The solid mashing tank that enters again of the filter of filter is beaten, while the temperature for being beaten tank being controlled at 90 degree or more, will be contained in filter admittedly
Some extractant azeotropic are taken out of, the extractant of the solid middle remaining of recycling filter.The material for being beaten tank is sent material to pressure by pump transport
Filter realizes the separation for filtering solid and filtrate by the constant pressure filtration of filter press.The filter of filters pressing enters IPA packaging system admittedly and is wrapped
Dress；The filtrate of filters pressing enters (containing catalyst) water phase of enriched catalytic agent, carries out catalyst recycling.

Tank 10 is starched, the filter filter that mashing tank 10 is used to accept in extraction filter admittedly is solid, filter mashing tank top connection extraction admittedly
Device, mashing pot bottom connects filter press 11 or cloth envelop collector admittedly for the filter；It is filtered in the filter press or cloth envelop collector
Liquid pipe road connects the water phase tank of enriched catalytic agent, and the filter press or cloth envelop collector, which are equipped with, filters solid discharge line.
Admittedly mashing pot bottom passes through pump connection filter press or cloth envelop collector for the filter.It is operated using filter press, filter cake
Smooth blanking and filter cake moisture content is low.
The decanter is sequentially connected the oily phase tank of enrichment benzoic acid, benzoic acid device is extracted in rectifying.
The water phase tank of the enriched catalytic agent connects sodium carbonate storage tank.The filter of extraction filter is solid enter again mashing tank into
Row mashing, while the temperature for being beaten tank being controlled at 90 degree or more, the extractant azeotropic contained in filter admittedly is taken out of, recycling filter is solid
The extractant of middle remaining.The material for being beaten tank is sent material to filter press by pump transport, real by the constant pressure filtration of filter press
Now filter solid and filtrate separation.The filter of filters pressing enters IPA packaging system 12 admittedly and is packed；The filtrate (contain catalyst) of filters pressing into
Enter the water phase of enriched catalytic agent, carries out catalyst and recycle.
