Abstract

An iron and oil removing filter for drainage comprises a shell body and at least one filter element arranged on a separating plate in the shell body, wherein the shell body comprises an upper closure head, a lower closure head, a water inlet, a water outlet and a discharge port, and the filter element is a three-layer composite filter element comprising an inner layer, a medium layer and an outer layer. The inner layer of the composite filter element takes a vertical tubular titanium alloy sintered filter element as a framework, the medium layer is composed of activated charcoal fibre felt winding round the titanium alloy sintered filter element, and the outer layer uses a stainless screen to fix and integrate the activated charcoal fibre felt and the titanium alloy sintered filter element. The iron and oil removing filter for drainage combines actions of activated charcoal adsorption and ultra-micro filtering to effectively remove expensive metallic ions including various oils, particulates, iron and brass in drainage, thereby purifying drainage. The iron and oil removing filter for drainage adopts an integration design of combining adsorption and ultra-micro filtering, simplifies the device structure, reduces the device size, and makes the automatic control of the device simpler and easier.

Description

Iron and oil removing filter for drainage
Technical field
The present invention relates to a kind of water treating equipment, particularly a kind of hydrophobic filter.
Background technology
In order to make full use of the energy and conserve water resource, hydrophobic recycling more and more obtains people's attention, all is widely used in petrochemical industry, electric power, therrmodynamic system.But the existence of high price ion, oil and various particulate matter such as the iron in hydrophobic, copper has limited hydrophobic recycling, is necessary to remove when reuse these pollutents.
The harm of the oil in hydrophobic mainly comprises: oil is decomposed into the very low dirt settling of thermal conductivity and has a strong impact on the tube wall heat transfer attached on the tube wall when being heated, cause tube wall flow of metal crisis boiler safety; Oil in the feedwater can make stove water form foam and very easily generate the grain slag deterioration steam quality of water float.
High price ions such as the iron ion in the boiler can cause following harm to boiler and piping system: form iron dirt or other metals dirt class on metal heated, not only influence heat transfer efficiency, even causing the local corrosion of metal, this corrosion generally is perforation or the explosion that pitting corrosion causes metal easily; The corrosion of metal product is taken to by steam and causes the successor devices salification in other successor devices, has a strong impact on the safe operation of equipment.
Particulate matter in hydrophobic may be in pipeline or equipment the formation of deposits dirt, not only influence heat exchange efficiency but also easily produce underdeposit corrosion and jeopardize the equipment operating safety.
The technology of existing hydrophobic deironing mainly comprises: ion exchange method, and ion exchange resin is poor to the tolerance of temperature, and non-refractory, has acid and alkali consumption, processing cost higher at the regenerative operation complexity.
The powder precoat filter, disposable utilization and operation cost height is if shop film inequality also influences the removal effect and the cycle of operation.
Electromagnetic filter influences treatment effect in the easy demagnetization of hot conditions magnetic filler, and impurity such as particulate matter and oil are covered magnetic fillers does not have good solution.
Existing hydrophobic degreasing technique mainly contains:
Gravity oil-removing, can there be certain limit in gravity settling institute by isolating oil droplet, and the oil in water emulsion very little for diameter do not have removal effect.
Gac, fruit stone oil removing, its principle is consistent with activated carbon fiber oil removing principle, but because the many inside at gac, fruit stone of the micropore of gac, fruit stone absorption oil removing are because the aperture is little and occupy nexine and be difficult to regeneration, disposable replacing running cost height, and depleted gac, fruit stone are not handled and are easily caused environmental pollution.
At present, the hydrophobic treatment device that also exists some complex processing systems that ultra filtration strainer and carbon fiber adsorption and catalytic combustion are combined, system complex, floor space are big, thereby equipment causes the running cost height to automatic control requirement height but this combination causes, and are difficult for deficiencies such as popularization on a large scale.
Summary of the invention
The invention provides a kind of iron and oil removing filter for drainage, solve that existing hydrophobic filter functions of the equipments are single, complex structure, floor space are big, equipment is to automatic control requirement height, technical problem that running cost is high.
The technical solution adopted for the present invention to solve the technical problems is:
This iron and oil removing filter for drainage, comprise filter body and at least one filter core of in housing, installing on the division plate, described housing has upper cover and lower cover, water-in, water outlet and sewage draining exit, described filter core is three layers of composite filter element, the internal layer of composite filter element be by upright piped titanium alloy sintered filter core as skeleton, the middle level is made of the activated carbon fiber felt that is wound in titanium alloy sintered filter core periphery; Skin is fixed as one activated carbon fiber felt and titanium alloy sintered filter core by Stainless Steel Cloth;
The two ends of described composite filter element are connected and fixed by the upper spacer and the lower clapboard of top connection and lower sub and enclosure interior, be filtering chamber between upper spacer and the lower clapboard, the below of lower clapboard is a water-purifying cavity, the tube cavity of composite filter element is connected with water-purifying cavity by lower sub, water-purifying cavity is respectively equipped with water outlet and sewage draining exit on side wall of outer shell, filtering chamber is provided with drain in the bottom, and top is provided with water-in.
Described upper cover periphery is fixed by holding bolt and housing, can be connected with the upper cover quick-opening device between upper cover top center and the housing.
Can have venting port on the described upper cover.
Described lower cover is to the water-purifying cavity medial eminence, and is connected with bearing rib between lower cover center and ground.
Described water-in can be connected with the water-in baffle plate in the housing inboard.
The filtering accuracy of described titanium alloy sintered filter core is 5 μ m~0.1 μ m.
The thickness of described activated carbon fiber felt can be 2~4mm, and the integral thickness after the winding is not less than 10mm.
