Embodiment Construction

[0023] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] The invention provides a technical solution: according to the attached Figure 1-2 It can be seen that this case is an intercepting composite membrane degreasing and iron removal process, which mainly includes: a housing 1, a water inlet 101 is provided at the bottom of the housing 1, an oil discharge port 102 is provided on the upper side of the side wall of the housing 1, and an outlet is provided at the top of the housing 1. The water port 103 is provided with a film-coated intercepting and oil-removing filter element 2 inside the housing 1 .

[0025] Wherein, the wire-wound filter element is provided with an oil and iron removal film composed of a lignocellulos...

Abstract

The invention relates to the technical field of purification of condensed water or other industrial water and discloses a film-coated interception oil and iron removal process. The device comprises ashell; a water inlet is formed in the bottom end of the shell; an oil stain discharge port is formed in the upper part of the side wall surface of the shell; at least one layer of oleophobic fiber short filaments or oleophobic fiber powder are paved on the outer wall of a wire winding filter element to form a film-coated interception oil removal filter element. The film-coated interception oil andiron removal process has the advantages that the design is reasonable; the respective advantages of a film-coated oil and iron removal technology and an interception oil and iron removal technology are absorbed; meanwhile, respective defects are avoided. That is to say, the advantages of simple equipment and small size of the composite membrane system are exerted, the problems of small pollutantholding capacity, frequent backwashing and more solid wastes of the composite membrane are avoided, the advantage of long operation period of the filter element of the interception oil removal technology is exerted, and the defects of large equipment size, high interception filter element manufacturing cost, inconvenience in replacement and the like of the interception oil removal technology are overcome.

Description

technical field [0001] The invention relates to the technical field of purification of condensed water or other industrial water, in particular to an intercepting composite membrane oil and iron removal process. Background technique [0002] In the process of industrial production, a large amount of steam is used as the heating medium, and a large amount of condensed water is produced at the same time. Effective recycling of condensed water can save a lot of water resources and water treatment costs. At the same time, the temperature of condensed water is high, which can reduce fuel consumption and has huge energy saving. and environmental benefits. [0003] However, during the formation of condensed water, due to the existence of iron equipment pipelines, condensed water will contain iron and other inorganic salts, and due to heat exchanger leakage, it will contain organic substances such as oil and other ions. If these impurities are removed, the condensed water will be fi...
