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
Technical field
The present invention relates to a kind of water treatment facilities, 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 particles such as the iron in hydrophobic, copper has limited hydrophobic recycling, is necessary to remove when reuse these pollutants.
The harm of the oil in hydrophobic mainly comprises: oil is decomposed into the very low attachment 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 pipe-line 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.
Particle in hydrophobic may deposit in pipeline or equipment and form dirt, not only influences heat exchange efficiency but also easily produces underdeposit corrosion and jeopardize the equipment security of operation.
The technology of existing hydrophobic deironing mainly comprises: ion-exchange, 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 particle and oil are covered magnetic fillers does not have good solution.
Existing hydrophobic degreasing technique mainly contains:
Gravity oil-removing, there is certain limit in the oil droplet that gravitational settling can separate, and the oil emulsion very little for diameter do not have removal effect.
Active carbon, fruit stone oil removing, its principle is consistent with NACF oil removing principle, but because the many inside at active carbon, fruit stone of the micropore of active carbon, fruit stone absorption oil removing are because the aperture is little and occupy nexine and be difficult to regeneration, disposable replacing operating cost height, and discarded active carbon, 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 filter and carbon fiber adsorption and catalytic combustion are combined, system complex, floor space are big, thereby equipment causes the operating 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 operating 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 housings and at least one filter core of in housing, installing on the demarcation strip, described housing has upper cover and low head, water inlet, delivery port and sewage draining exit, described filter core is three layers of composite filter element, the internal layer of composite filter element be titanium alloy sintered filter core by the standpipe shape as skeleton, the middle level is made of the NACF felt that is wound in titanium alloy sintered filter core periphery; Skin is fixed as one NACF 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 contact and enclosure interior, be filter 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 contact, water-purifying cavity is respectively equipped with delivery port and sewage draining exit on side wall of outer shell, filter chamber is provided with drain in the bottom, and top is provided with water inlet.
Described upper cover periphery is fixed by fastening bolt and housing, can be connected with the upper cover quick-opening device between upper cover top center and the housing.
Can have exhaust outlet on the described upper cover.
Described low head is to the water-purifying cavity medial eminence, and is connected with bearing rib between low head center and ground.
