Background technology
The own aqueous solution mixes rear and hydrogen generation hydrogenation reaction with Raney's nickel catalyst in hydrogenation reactor in caprolactam refining technique, own water liquid behind the hydrogenation enters the filter charging spout, and by being pumped to catalyst filter, when the pressure reduction of filter is too high, to switch cleaning to filter, wash the catalyst that comes and reclaim.What filter often adopted is plate frame filter, and cleaning filter need to be taken the shell flange bolt apart, cylindrical shell is removed water flushing filter plate; The actual moving process middle filtrator cleans frequent, cleans institute and consumes that time-consuming is grown, manpower is many.The Raney's nickel of participating in simultaneously after the reaction still may contain a large amount of hydrogen, is exposed to inflammablely in the air, explosive, takes when cleaning the misoperation accident of then easily blasting apart at filter, adopts this kind filter to have a lot of potential safety hazards.Therefore, for the problems referred to above be the object of the utility model research.
Summary of the invention
The purpose of this utility model is to provide a kind of catalyst filter, this device not only simple in structure, design is ingenious, can realize full-automatic online backwashing, the equipment cycle of operation is long, and is conducive to reduce human and material resources and wastes.
Feature of the present utility model: a kind of catalyst filter, comprise filter cylinder and be located at some groups of interior filter cores of filter cylinder, one side of described filter cylinder is provided with to control the charging control valve that material enters, another side is provided with to control the discharge header pipe that material discharges and is arranged on discharging control valve on the discharge header pipe, described discharge header pipe also is connected with the discharging arm of every group of filter core respectively, it is characterized in that: also be respectively arranged with repid cut-off valve on the discharging arm of every group of filter core, also otherly respectively on the discharging arm between described repid cut-off valve and the corresponding filter core be connected to control gas transmission arm and the gas transmission control valve thereof that nitrogen is carried.
The beneficial effects of the utility model are: the utility model filter element is divided into some groups, every group of filter core all can carry out separately backwash regeneration, regeneration does not affect again the normal operation of other group filter cores simultaneously, under the control of controller, some set filters sequentially carry out backwash regeneration by setting, filter regeneration does not need to take apart filter seal head, has realized the full-automatic on-line cleaning of filter, and the equipment cycle of operation prolongs greatly.
Description of drawings
Fig. 1 is the schematic block diagram of the utility model syndeton.
The specific embodiment
For above-mentioned feature and advantage of the present utility model can be become apparent, embodiment cited below particularly, and cooperation accompanying drawing are described in detail below.
With reference to figure 1, the utility model relates to a kind of catalyst filter, comprise filter cylinder 10 and be located at the interior some groups of filter cores 3 of filter cylinder, one side of described filter cylinder 10 is provided with to control the charging control valve 1 that material enters, another side is provided with to control the discharge header pipe that material discharges and is arranged on discharging control valve 9 on the discharge header pipe, described discharge header pipe also is connected with the discharging arm of every group of filter core 3 respectively, also be respectively arranged with repid cut-off valve 2 on the discharging arm of every group of filter core 3, also otherly respectively on the discharging arm between described repid cut-off valve 2 and the corresponding filter core 3 be connected to control gas transmission arm and the gas transmission control valve 8 thereof that nitrogen is carried.
Above-mentioned gas transmission arm links to each other with gas transmission main behind the gas transmission control valve 8 of correspondence, also is provided with one way stop peturn valve 6 and Self-operated pressure control valve 7 on the described gas transmission main.
The upper end of above-mentioned filter cylinder 10 is provided with to discharge the gas exhausting valve 4 of nitrogen.
The lower end of above-mentioned filter cylinder is provided with the slagging coutrol valve 11 of discharging filter residue in order to control.
Differential manometer 5 also is installed between above-mentioned filter cylinder and the discharge header pipe.
Specific implementation process:
The filter of the full-automatic on-line cleaning of the utility model comprises filter cylinder 10, and filter element 3 is installed in the cylindrical shell, and filter core 3 is divided into some groups.Every group all can be carried out independent online backwashing cleaning, on every group of filter core discharging pipeline repid cut-off valve 2 be installed; The online backwashing of filter core realizes that by closing the nitrogen that passes into certain pressure behind the repid cut-off valve nitrogen is equipped with one way stop peturn valve 6, Self-operated pressure control valve 7 by gas transmission control valve 8 controls on the pipeline on the nitrogen gas transmission main;
Charging control valve 1 control material feeding is installed on the filter feeding line.
When the filter core inside and outside differential pressure reached setting value, controller began backwashing procedures, closes repid cut-off valve 2, open nitrogen gas transmission control valve 8, the outer filter cloth of filter core is expanded by interior pressure outward, and the catalyst filter residue that is attached on the filter cloth breaks, drops, and collects in filter bottom.
The filter core inside and outside differential pressure records by being installed in the differential manometer 5 of installing on filter cylinder and the material discharge header pipe line, and pressure difference signal is sent to controller PLC.
The filter conical lower portion is installed slagging coutrol valve 11, is used for discharging fast the filter residue that collects in filter bottom.
Filter top is equipped with exhaust line, and gas exhausting valve 4 is installed on the pipeline, the nitrogen by being filled with in gas exhausting valve 4 discharge filters after backwash is finished;
Valve 1,2,4,8,9,11 moves by the program that sets automatically by field controller PLC control.
The workflow of the filter of the full-automatic on-line cleaning of the utility model, material enters filter by charging control valve 1, by filter core 3, enter next flow process by discharging discharging control valve 9 after filtering out catalyst, when filter pressure reduction reaches when setting value, first group of filter core regeneration is cleaned in controller control, finish cleaning after this set filter come into operation, when filter pressure reduction reached setting value again, the controller control system was carried out second group of filter core regeneration.So by setting sequential loop regeneration filter core, realized the full-automatic on-line regeneration of filtration system.
The utility model does not limit to above-mentioned preferred forms, and anyone can draw other various forms of catalyst filters under enlightenment of the present utility model.All equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
