Technical field
The present invention relates to a kind of filter mechanism, particularly a kind of pre-filtered bi-directional two stage composite filter structure of boats and ships oil water separator membrane separation device that is used for.Belong to environmental protection technical field.
Background technology
The MPEC.107 (49) that passes through according to Maritime Environment Protection Committee of International Maritime Organization newly resolves; the boats and ships that regulation is built now must be installed the novel oil water separator that oil drain quantity is no more than the 15PPM oily mixture; when meeting the oil water separator of new regulation, our exploitation finds; carry out film when separating to separate the emulsion got rid of behind most of oil slick through machinery; because advance the complicated component of film emulsion; contain more major diameter particulate matter; as materials such as tri-iron tetroxides; this type of material directly advances the performance and the life-span that can have a strong impact on film behind the film; make very fast obstruction of film even inefficacy and the membrane module of having to often change; to make the expense of system maintenance difficulty and maintenance increase greatly, to have designed a preposition prefilter that shields in order addressing this problem.In existing technology, application number is 94238960.3, name is called the utility model patent of hydraulic pilot logic suitching type twin strainer, this filter is a logical oily oil-break of controlling left and right sides filter by the hydraulic system transfer valve, and the hydraulic system Installation and Debugging of this filter are loaded down with trivial details, system's instability, the input cost height, and each does not meet the liquid of composition complexity to having only one-level to filter, and filter core stops up easily; Application number is 98233324.2, and name is called the utility model patent of duplex lubricating oil filter, is to be used for the diesel engine of locomotive supercharger systems, and duplex lubricating oil filter automaticity is not enough, and the design that is not optimized of the filtering accuracy of filter, and filter core needs frequent replacing.
Summary of the invention
Deficiency and defective in order to overcome prior art the invention provides a kind of bi-directional two stage composite filter structure, as the preposition prefilter in the boats and ships oil water separator membrane separation device.Only need one during operate as normal to directional two stage composite filter work, another to directional two stage composite filter as standby filter.Wherein the filtering accuracy of two of directional two stage composite filter filter cores obtains optimum Match, has prolonged the service life of filter core; The signal that adopts PLC to receive differential pressure pickup is controlled two-position three way magnetic valve automatically, with realize when working one when directional two stage composite filter takes place to stop up, use another to directional two stage composite filter, make whole system continue normal operation, change two filter cores of the directional two stage composite filter that has stopped up.Thereby effectively protected membrane module, improved the stability of whole oil water separator.
The present invention realizes by following technical proposals: the present invention includes base plate, A two-bit triplet magnetic valve, B two-bit triplet magnetic valve, A directional two stage composite filter, B directional two stage composite filter, differential pressure pickup, control module.Wherein A directional two stage composite filter and B directional two stage composite filter all adopt two oil screen series connection casting all-in-one-piece structures of design voluntarily, the filtering accuracy of two filters obtains the optimum optimization coupling under verification experimental verification, A directional two stage composite filter and B directional two stage composite filter are fixed on the base plate.The outlet that a port of A two-bit triplet magnetic valve separates with machinery links to each other, two ports link to each other with the import of A directional two stage composite filter with the B directional two stage composite filter respectively in addition, a port of B two-bit triplet magnetic valve links to each other with the import of membrane module, two ports link to each other with the outlet of A directional two stage composite filter with the B directional two stage composite filter respectively in addition, the outlet that two inputs of differential pressure pickup separate with machinery respectively and the import of membrane module link to each other, the output of differential pressure pickup is electrically connected with the input of control module, and the output of control module is electrically connected with the control end of A two-bit triplet magnetic valve and B two-bit triplet magnetic valve respectively.Control each magnetic valve auto-action by control able to programme (PLC) device, with realize when working one when directional two stage composite filter takes place to stop up, use another to directional two stage composite filter, make whole system continue normal operation, change two filter cores of the directional two stage composite filter that has stopped up.
Beneficial effect of the present invention: the present invention adopts unique integrated optimal design of directional two stage composite filter, make the filtering accuracy of two filter cores obtain optimum Match, filter effect is remarkable, the filter core long service life, simple in structure, low cost, adopt the signal of PLC reception simultaneously from differential pressure pickup, automatically control two-position three way magnetic valve, with realize when working one when directional two stage composite filter takes place to stop up, use another to directional two stage composite filter, make whole system continue normal operation, change two filter cores of the directional two stage composite filter that has stopped up, improved the stability of system greatly.Because filter core with low cost, greatly reduce the cost of maintaining when having protected membrane module in addition, have remarkable economic efficiency and social benefit.
