Description
Technical field
The utility model is related to PTMEG preparation fields more particularly to a kind of cleaning systems of catalyst filter.
Background technology
In PTMEG production technologies, catalyst fine filter (F9601) is last in PTMEG process of producing product
Road critical point, it is therefore an objective to contaminant filter remaining after filter press get off, ensure that the turbidity of final products is qualified, the pressure difference of filter
Can with run time, payload variation and gradually increase, under normal circumstances, F9601A/B switching frequencies be 5 times/month,
After having switched F9601 every time, the filter element being switched out is cleaned, technologist is by F9601 before cleaning
Interior remaining PTMEG is emitted into ton bucket, then removes top end socket, takes out filter core, connect the connector of cleaning, connects hose steaming
Vapour condensate liquid back flushing filter core, whole process is comparatively laborious, and workload is larger, and the PTMEG products being discharged every time are taken out when waste liquid, warp
Ji loss is larger, manually cleans filter core, and there are some potential safety problemss, and is easy to make filter core dilatancy, shortens filter
Core service life increases production cost.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of filter core service life long, cleaning efficiency height, operation
Simply, the cleaning system of low-cost catalyst filter.
The technical solution that the utility model solves above-mentioned technical problem is as follows:
A kind of cleaning system of catalyst filter, including filter are equipped with filter core, the filter core in the filter
Metallic framework is installed in outside, and the filter top end installs dismountable flange lid, and the dismountable flange is covered equipped with pipeline, institute
Piping connection nitrogen purging metal hose is stated, the filter bottom end passes through piping connection blowback material receiving tank.
Preferably, the metallic framework is fastened on filter core mounting flange on filter core metab.
Preferably, the cleaning system further includes that product receives storage tank, the product receive storage tank by piping connection with
Filter.
Preferably, the pipeline of the connection nitrogen purging metal hose is equipped with pressure gauge on the spot.
Preferably, it connects in filter and the pipeline of blowback material receiving tank and valve is set, main function is that low spot is led
Leaching, for emptying the liquid in pipeline.
Preferably, the cleaning system further includes pressure difference display, the pressure difference display by piping connection filter,
The pipeline is equipped with pressure gauge before and after filter core;Pressure gauge main function is pressure before and after observation filter core before and after installation filter core, is led to
It crosses pressure before pressure after calculating filter subtracts filter and obtains pressure difference, pass through the pressure difference height on pressure difference display, judge
By impurity stopping state during filter core use, pressure difference reaches 100KPa and can be carried out switching cleaning step under normal circumstances.
Utility model device is run in the following manner:
Filter core in the utility model filter, outer protection is changed to metallic framework formula by original hood type, in backwash
During filter core will not be caused to deform or damaged, improve the service life of filter core;This practicality cleaning way is will be original
Cartridge removal cleaning of getting off is changed to utilize nitrogen blowback, by PTMEG products in filter core and remaining diatomite impurity blowback to anti-
It blows in material receiving tank, filter top is led to the nitrogen of leaching connection by metal hose 6bar, bottom is led leaching and is connected to back to anti-
On the pipeline for blowing material receiving tank, when filter differential pressure height, it is switched to reserve filter, the filter being switched out is directly logical
Cross top plus nitrogen, by filter PTMEG products and diatomite impurity be blown in blowback material receiving tank and store together
Come, next filter press can be used when precoating, not only reduce waste, also reduce field labor intensity.
Compared with prior art, the utility model has the beneficial effects that:
1, original filter core outer protection is changed to metallic framework formula by the utility model by hood type, during backwash not
Filter core deformation or damaged can be caused, improves the service life of filter core, every filter core can be used 5 months or so, and reduction is produced into
This.
2, the utility model uses nitrogen purge system, and cartridge removal is got off with nitrogen blowback, PTMEG in filter core is produced
In product and remaining diatomite impurity blowback to T9504, next filter press re-uses when precoating.
3, using the utility model cleaning system, one Secondary filter of cleaning only needs 2 hours or so, improves cleaning filter core
Efficiency especially in case of emergency can be to avoid because spare filter core could not clean back and be attached to position and system is caused to drop in time
Load or parking.
4, using the utility model cleaning system, it is possible to reduce the waste of PTMEG products, it every year can be cost-effective
216000 yuan.
5, using the utility model cleaning system, without dismounting filter core when cleaning filter core, keeping away reduces because dismounting filter core
The dangerous risk such as high falling, the scald of generation.
