Abstract

The utility model discloses a flat pre-coating filter bag. One edge of the filter bag is provided with an opening and the other three edges are all closed ones. The edge with an opening is disposed with a row of fixed holes and the opposite edge of the edge with an opening is also equipped with through-holes. Coated on the external side of a plate-shaped filter element and vertically mounted in a square filter chamber with a constant pressure, the filter bag is used for the process of pre-coating covering and filtering. The addition of diatomite, powdered active carbon as well as pulverized fodder like resin powder into the process of filtering helps form a dynamic micro-film through which materials as small as a micrometer can be filtered. One beneficial effect of the utility model lies in that the flat pre-coating filter bag is applicable to a dynamic micro-film chamber. With a low cost needed for the manufacture, the filter bag has a good quality to filter materials.

Description

Flat precoat filtration bag

Technical field

The utility model relates to water treatment field, specifically a kind of flat precoat filtration bag.

Background technology

Along with The development in society and economy, people are to the further raising of environment protection demand, the further developing of water-treatment technology field, and new water treatment system constantly occurs.Existing filter bag filtering accuracy is lower; Filter cycle of operation weak point; The regeneration difficulty: work-ing life is short, needs often to change and safeguard.

Summary of the invention

The utility model purpose is to provide a kind of flat precoat filtration bag, and this filter bag is carried out precoating, realizes making water outlet reach requirement to raw water filtration and adsorption treatment.

In order to realize this purpose, the technical solution of the utility model is as follows: a kind of flat precoat filtration bag, it is characterized in that this filter bag openings at one side, and other three banding closes, this filter bag open side is provided with fixed orifices, and the opposite side relative with open side also is provided with fixed orifices.This filter bag is enclosed within outside the filter plate, and the filter bag outside is provided with pressing plate, and the fixed orifices by filter bag is connected with filter plate.The filter bag material is terylene, polyester, polyamide fibre or non-woven fabrics, and weaving method adopts plain weave, twill or satin weave, and filter bag adopts single multifilament filter cloth to shape.The filter bag outside surface is provided with the thick dynamic micro filter film of 1.5mm~3mm.

Filter bag is sleeved on the plate shape filter element outside, is vertically mounted among the square filter tank of normal pressure, is used to the covering filtration process with precoated layer.In filtration, add powders such as diatomite, Powdered Activated Carbon, resin-oatmeal and form the dynamic micro filter film, realize that the normal pressure of micron level material filtering and feedwater clarification filtration aspirates board-like filter element at the filter element outside surface.Advantage of the present utility model is to be applicable to dynamic micro filter film forming filter tank, and its cost is low, good filtration effect; The filtration cycle of operation is long; Regeneration is easy: long service life, safeguard simple.
