Abstract

The invention relates to water treating equipment. Its design project: installing filter core in the shell of the fine filter, wherein the filter core is made by coiling compact electropositive non-woven fabrics, a permeable tube with hole on the surface is in the center of the filter core, and sewage inlet and clear water outlet are set on two ends of the shell, respectively. The sewage inlet is linked with the sewage pump through the pipeline and the clear water outlet linked with the pipeline which is linked with the flowmeter. The shell is linked with the recoil water inlet and outlet, and the recoil pump is linked between them through the pipeline. It heightens the filtering efficiency, avoiding the jam.

Description

Positive electricity rolling fine filter

Technical field

The present invention relates to environmental protection equipment, specifically a kind of water treatment facilities.

Background technology

The re-injection of water reuse and petroleum recovering water during fine filter is mainly used in.In industries such as oil, all can produce a lot of waste water every day, is the conserve water resource, need recycle these waste water.Because the composition in the sewage is very complicated, even, still contain impurity such as a large amount of SS floating things, bacterium, oil emulsion, COD, BOD, heavy metal in the water through after the common sewage disposal device processing; After adopting secondary filter, generally can remove in the water greater than the solid particle more than 0.5 micron, but other impurity then can't remove, stop up the purpose of water reuse in therefore not reaching easily because filter area is little.If employing ultrafilter or reverse osmosis unit are handled the impurity in the water, its molecular weight of holding back is between 80000～600, because ultrafilter or reverse osmosis unit can not use separately, must add accurate filter, sand filter, active carbon filter, ion-exchanger and equipment such as backwashing system and control system in the processor front, one-time investment is bigger, and operating cost and upkeep cost are than higher.

Goal of the invention

The objective of the invention is to design a kind of positive electricity rolling fine filter, this fine filter utilizes dense nonwoven to form the rolling filter core, on filter core, be coated with the material of positively charged again, thereby improved the filter efficiency of equipment, problems such as obstruction have been avoided, reduced equipment investment, and operating cost and upkeep cost.

According to design provided by the present invention, the nonwoven fabric roll of in the shell of fine filter the positively charged that utilizes densification being installed is surface water-permeable pipe with holes around the filter core that forms at the middle part of filter core, at the two ends of shell sewage import and clear water output is set respectively.

Further feature is: utilize pipeline to connect sewage pump, connecting pipe on clear water output, connection traffic meter on pipeline in the sewage import.On the shell of fine filter, connect recoil water inlet and recoil water out, and between recoil water import and export, utilize pipeline to connect the recoil water pump.

Further feature is: a plurality of fine filters are installed in the bracing frame side by side, and the sewage import on each fine filter all utilizes pipeline to be connected with sewage pump, and the recoil water entrance on each fine filter all utilizes pipeline to be connected with the recoil water pump.

Advantage of the present invention is: owing to utilize the nonwoven fabric roll coiled filter core of dense positively charged, thus improved the filter efficiency of equipment, avoided problems such as obstruction, reduced equipment investment, and operating cost and upkeep cost.

The specific embodiment

As shown in the figure: in the shell 9 of fine filter 2, install and utilize fine and close nonwoven fabric roll around the filter core 15 that forms, on filter core 15, be coated with the material that has positive electricity again, at the middle part of filter core 15 is surface water-permeable pipe 10 with holes, and sewage import 14 and clear water output 11 are set respectively at the two ends of shell 9.During work, sewage enters in the filter core 15 through pipeline 5 and sewage import 14, and clear water permeates to filter core 15 in, pass water-permeable pipe after, through the clear water output discharge, impurity is blocked by filter core, thereby plays the purpose of filtered water.Fine and close nonwoven helps to improve the intensity of filter core, behind the material that has been coated with positively charged on the filter core, can with electronegative interaction and impurities in the water, impurity absorption on filter core, is improved the water treatment effect.

Utilize pipeline 5 to connect sewage pump 6 in sewage import 14, connecting pipe 1 on clear water output 11, connection traffic meter 8 on pipeline 1.Clear water is aggregated in the pipeline 1 after clear water output is discharged.

On the shell 9 of fine filter 2, connect recoil water inlet 13 and recoil water out 12, and utilize pipeline 4 to connect recoil water pump 7 13,12 of recoil water import and exports.After using a period of time, can gather impurity in the filter core, when this impurity acquires a certain degree, can have a strong impact on treatment effect, therefore, should regularly remove.When removing, start the water pump that recoils, recoil water is entered in the water-permeable pipe of fine filter through the recoil water inlet, permeate to the filter core that is positioned at the outside through the hole on the water-permeable pipe again, the impurity that is adsorbed on the filter core is rinsed well.

Usually, for improving treatment effect, a plurality of fine filters 2 can be installed in the bracing frame 3 side by side, the sewage import 14 on each fine filter 2 all utilizes pipeline 5 to be connected with sewage pump 6, and the

recoil water entrance

13,12 on each fine filter 2 all utilizes pipeline 4 to be connected with recoil water pump 7.
