Abstract

The utility model discloses a gravity separator used to separate the solids and the oil in the waste water, comprises a housing, and a nested water outlet pipe. The inner pipe is a water inlet pipe, and the casing tube is a water outlet pipe. A pair of water distributing funnels arranged back to back in the middle part of a separating chamber, the water inlet funnel is connected with the water inlet pipe downwards, and the water outlet funnel is connected with the water outlet casing tube upwards. A separating sloped plate group is fixed and supported in the position horizontal to the funnel, a mud discharge pipe is arranged on the bottom of the separating chamber, and an oil discharge pipe is arranged on the top. The downward side of the sloped plate is coated with polypropylene or other oleophilic nonpolar materials, and the efficiency of the solid and oil water separation in the waste water is improved by utilizing the superficial layer precipitating mechanism and the coarse granulating mechanism.

Description

Gravity separator for solid oil and water

The design belongs to wastewater treatment equipment, particularly utilizes Gravity Separation solid, You Heshui.

In industrial production such as iron and steel, machinery, oil, chemical industry, can produce the waste water that contains body refuse, greasy dirt, enter environment and can produce pollution and reduce environmental self-purification capacity.Separate the solid in the waste water, as mud, slag and greasy dirt, the device that has adopted at present has multiple, and advanced a kind of gravity separator as shown in Figure 2.Sewage is entered by the separator bottom, and the middle part flows into the separation chamber through the water distribution funnel along pipeline to separator, enters outlet pipe through water outlet water distribution funnel again, utilizes the gravity effect that the solid body refuse is sunk in the sewage flow process, the oil come-up, and water enters drainpipe and discharges from the middle part.The shortcoming that this device exists is that the waste water separation process is short, the efficient that influence is handled.

The design's purpose is to increase the flow process of waste water separation and improve separation condition under the situation that does not change above-mentioned whole separator structure, improves waste water treatment efficiency.

The design's content is to be provided with to separate the swash plate group in the separation chamber of separator, and the swash plate group is with on the position that is supported and fixed on Inlet and outlet water mouth of pipe water distribution funnel maintenance level.Second content of the design is with the inlet tube and outlet tube suit, and water inlet pipe is interior pipe, and outlet pipe is an outer tube.

The design's advantage is to be provided with swash plate can increase the waste water separation process, and utilizes the mechanism of shallow layer precipitating, has enlarged the area of solid precipitation in the waste water, improves the solid water separative efficiency.The opposite side of swash plate can be coated with the non-polar material of oleophylic, for example polypropylene.Small oil is adsorbed easily and accumulates in its surface, helps the coarse of tiny oil droplets, and and then raising water-oil separating efficient.Another advantage of the design is with the water inlet pipe and water outlet pipe suit, and this mode makes things convenient for the dismounting of whole separator.

The design's embodiment as shown in Figure 1.

To illustrated explanation:

Water inlet pipe 1, outlet pipe 2, separator top cover 3, separation chamber 4 separates swash plate group 5, oil exit pipe 6, water outlet water distribution bucket funnel 7, shell separator 8, water inlet water distribution funnel 9, swash plate supports 10, separator support 11, discharge pipeline 12, overcoat outlet pipe 13.

Operation instruction to present embodiment:

Waste water flow to water distribution funnel 9 by water inlet pipe 1 and enters 4 bottoms, separation chamber, oppositely goes up through separating swash plate group 5 and enters 4 tops, separation chamber, oppositely enters out jacket pipe 13 through water inlet water distribution funnel 7 down again, by outlet pipe 2 drainings.Body refuse in the waste water 4 bottoms, separation chamber with separate the swash plate group in the waste water precipitation separation, amass in separator bottom.Can discharge by discharge pipeline 12.Oil in the waste water, through separate swash plate group 5 coarses and in the separation chamber 4 tops separate with the waste water of reverse current downflow, discharge by the oil exit pipe 6 at top.

The separation swash plate that the design adopts can have various ways, and swash plate as shown in Figure 1 is the swash plate that is waist drum shape concentric arrangement, also can adopt " chevron " swash plate group of being produced by Chagghong Plastics Factory, Chengdu City at present, or other kind swash plate.

Claims

1, a kind of solid, oily, water gravity separator, comprise water inlet pipe, outlet pipe, Inlet and outlet water mouth of pipe water distribution funnel, discharge pipeline and oil exit pipe is characterized in that having and separate the swash plate group, and the swash plate group is with on the position that is supported and fixed on water-in and water-out mouth of pipe water distribution funnel maintenance level.

2, a kind of separator as claimed in claim 1 is characterized in that inlet tube and outlet tube is a sleeve pipe, and water inlet pipe is interior pipe, and outlet pipe is an outer tube.
