Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-2, a petrochemical organic amine solution mechanical filter element comprises an upper end cover 2, a lower end cover 7 and a framework 6, wherein a fine filter layer 5, an activated carbon adsorption layer 4 and a coarse filter layer 3 are sequentially arranged outside the framework 6, two ends of the framework 6, the fine filter layer 5, the activated carbon adsorption layer 4 and the coarse filter layer 3 are respectively fixed on the upper end cover 2 and the lower end cover 7, and sealing gaskets 1 are further fixed on the upper end cover 2 and the lower end cover 7.

The contact parts of the upper end cover and the lower end cover with the framework 6, the fine filtering layer 5 and the coarse filtering layer 3 are bonded by glue. The activated carbon adsorption layer 4 is formed by adding an adhesive into activated carbon particles, heating and sintering, and continuously extruding, so that the filter element has excellent adsorption performance of the granular activated carbon and precise filtration characteristic of a tubular element.

The fine filter layer 5 and the coarse filter layer 3 are glass fiber filter layers or polyester fiber filter layers. The fine filter layer 5 is used for filtering particles in liquid, coarse filtering the particles to 20-50 microns, filtering large-particle substances such as rust, water, oil and the like in a pipeline, and the activated carbon adsorption layer is used for removing color and filtering organic matters and metal ions and adsorbing impurities. The framework 6 is a stainless steel framework.

The utility model relates to a mechanical filter element of an organic amine solution, which is formed by processing a plurality of composite materials, has hydrophilic property, not only can filter mechanical impurities in a medium, but also can separate water in an emulsified state from the medium through demulsification and coalescence, and coalesce into larger water drops, so that the purification of the medium is further realized. The filtering principle is as follows: the droplets of oil, water and other liquids are captured by the superfine fibers (namely the fine filter layer 5 and the coarse filter layer 3) in the filter element, the micron-sized fibers form a tortuous channel for air flow, solid particles and liquid droplets are forced to be captured by the superfine fibers under the action of three filtering mechanisms of inertial collision, diffusion interception and direct interception, and the small droplets are aggregated into larger droplets due to the surface tension of the liquid, so that the large droplets are settled to the bottom of the container due to the action of gravity.

The filter element is made of high-density gradient glass fiber or polyester fiber, is designed into an integral single-piece tube structure for reducing breakage and leakage, and the surface of the filter element is subjected to hydrophobic and oleophobic treatment, so that the requirements of various precision grades can be met.
