Further improvement of the utility model is: the cleaning filter mode is gas-vapor mix blowback and spray.
The beneficial effects of the utility model are: the plum blossom pillar frame of filter element of the utility model is 5 punching cylindrical tube compositions,
It is arranged closely together to form plum blossom-shaped, skeleton wraps up PTFE filter cloth, the filtering of normal filtration ecto-entad, and PTFE filter cloth closely covers
It is pressed on skeleton, the flexible space of PTFE filter cloth during blowback, vibration removes Raney's nickel catalyst filter cake, solves tradition
Metal filtering core filter it is easily stifled and can not regeneration washing the problem of restoring, reduce operating cost, reduce maintenance cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the top partial view diagram of the utility model.
Specific embodiment
In order to deepen the understanding to the utility model, the utility model is done further below in conjunction with drawings and examples
Detailed description, the embodiment are only used for explaining the utility model, do not constitute and limit to the protection scope of the utility model.
As shown in Figs. 1-2, the utility model is a kind of devitalized Raney's nickel filter, the filter be SUS304 or
Filter made of SUS316L, including filter housings 1, filter end cap 2, filter collet 3, the filter collet 3
Charging medium is conduction oil, hot steam or hot water, passes through heat exchange, control temperature of charge >=60 DEG C, in the filter housings 1
On be provided with purified liquor outlet 4, A group liquid collecting pipe valve 5, B group liquid collecting pipe valve 17, material inlet 6, slag-drip opening 7, plum blossom pillar filter core 8, collection
Liquid pipe 9, back blow port 18, collector tube 9 include A group collector tube and B group collector tube, and the purified liquor outlet 4 and the back blow port 18 are logical
