Abstract

The utility model relates to an oily sewage filter used for the environmental protection of chemical industry and mainly solves the problems that the processing effect of the existing filtering device is poor and the water quality of the processed oily sewage cannot reach standards. The oily sewage filter is characterized in that a plurality of oil and dirt separating ports are formed at the top of a filter tank body (10), and the oil and dirt separating ports are connected by a common oil discharging channel (5); S-shaped water baffles (4) are arranged in the filter tank body (10) in a crossed way, gas spray heads (12) are arranged between every two baffles, and a multi-phase pump provides the gas spray heads (12) with a gas source; and a spiral water channel (9) with variable pitch angles, provided with a cyclone water-in pipe (7), is fixedly arranged at the part of a sewage inlet (8), and a plurality of liquid-in holes (6) are formed in the channel. The three modes of gas floatation, water cyclone and internal filter media are integrated in the filter, so that the filter media keep an efficient filtering function. The oily sewage filter has the characteristics of high oil removing efficiency and excellent sewage processing effect.

Description

The oil-containing sewage filter that is used for environmental protection
Technical field
The utility model relates to a kind of sewage-treatment plant for the environmental protection field.
Background technology
At present, domestic city is processed the higher sewage of oil-containing quarrel composition does not still have suitable device, and most devices are comprised of water-oil separating and filter.Oily-water seperating equipment adopts natural subsidence combination waste-oil scavenger, and filter adopts walnut shell, quartz sand and glauconite filter.These existing treating apparatus in use are found to exist following problem: at first, owing in order to guarantee that sewage disposal can reach standard, need to add a large amount of efficiently demulsifying flocculants in the processing procedure, cause processing rear system and produce a large amount of scum silica frost; Secondly, water viscosity strengthens in the sewage, causes greasy dirt and filtrate adhesion to increase, for lightweight shell filtrate, its relative density further reduces, it is too high to cause easily the backwash filtrate to expand, and it is serious to build the pressure, run the material problem, and for the heavy filtrate, be easy in the filter process at the gluey hardening layer of filtrate top layer formation one deck, be difficult for fragmentation, cause backwash effect to descend, be difficult to realize the thorough regeneration of filtrate; Again, be that added amount of chemical is large, operating cost is high, produces simultaneously a large amount of scum silica frost, and there is no at present ripe technology for the processing of scum silica frost.In sum, there is the problem that oil removal efficiency is not high, the scum silica frost generation is excessive and inner filtrate is difficult to regenerate in existing urban sewage treating device when processing the higher sewage of oil-containing quarrel composition.
Summary of the invention
In order to solve the problems of the prior art that propose in the background technology; the utility model provides a kind of oil-containing sewage filter for environmental protection; this kind device combines air supporting, hydraulic cyclone and three kinds of modes of inner filtrate; so that filtrate keeps efficient filtration, have the characteristics of oil removal efficiency height, good sewage processing effect.
The technical solution of the utility model is: this kind is used for the oil-containing sewage filter of environmental protection, has a filter tank body, have sewage inlet, outlet of sewer and access hole at tank body, in tank body, be fixed with the filtrate shelf, its unique distinction is: the top of described filter tank body has some greasy dirt separating openings, and described greasy dirt separating opening is connected by public oil drain passage; Cross arrangement has serpentine current baffle plate in described filter tank body, is provided with the gas-sparging head that source of the gas is provided by multiphase pump in the middle of per two baffle plates; Described sewage inlet place is fixed with the change lift angle spiral water flow passage with the eddy flow water inlet pipe, has some inlet openings on this passage.
In addition, on above scheme basis, can further improve, namely have a round mouth at the top of described filter tank body near filtrate shelf one side, built-in by pull bar and the oil removing mechanism that consists of after skiving blade is connected, described pull bar can drive skiving blade and slide along the guide rail in the tank body.
The utlity model has following beneficial effect: take such scheme and the device that consists of, has the gas-sparging head that source of the gas is provided by multiphase pump, so that water body produces a large amount of micro air bubbles, can be attached on the impurity particle that contains greasy dirt, because density is floated to the water surface less than water thus.Simultaneously, along continuous straight runs serpentine baffle plate arranged in a crossed manner in tank body so that sewage flows along baffle plate is snakelike, has improved water-oil separating efficient in the pond.In addition, be fixed with the change lift angle spiral water flow passage with the eddy flow water inlet pipe at the sewage inlet place, have some inlet openings on this passage, like this, under the hydraulic cyclone effect, utilized the profit density contrast, on the upper strata, and water is in lower floor by self-pressure effect oil float.In addition, built-in by pull bar and the oil removing mechanism that consists of after skiving blade is connected at the filter tank body under preferred embodiment, like this, the greasy dirt of filtrate shelf surface can be struck off and prevent from stopping up.This kind device combines air supporting, hydraulic cyclone and three kinds of modes of inner filtrate, so that filtrate keeps efficient filtration, has the characteristics of oil removal efficiency height, good sewage processing effect.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
1-outlet of sewer among the figure, 2-filtrate shelf, the 3-skiving blade, 4-current baffle plate, the 5-oil drain passage, the 6-inlet opening, 7-eddy flow water inlet pipe, 8-sewage inlet, 9-become lift angle spiral water flow passage, 10-filter tank body, 11-access hole, 12-gas-sparging head.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this kind is used for the oil-containing sewage filter of environmental protection, comprises filter tank body 10, has sewage inlet 8, outlet of sewer 1 and access hole 11 at tank body, is fixed with filtrate shelf 2 in tank body.On above conventional scheme basis, this kind device also comprises following content:
The top of described filter tank body 10 has some greasy dirt separating openings, and described greasy dirt separating opening is connected by public oil drain passage 5; In described filter tank body 10 interior cross arrangements serpentine current baffle plate 4 is arranged, in the middle of per two baffle plates, be provided with the gas-sparging head 12 that source of the gas is provided by multiphase pump; Described sewage inlet 8 places are fixed with the change lift angle spiral water flow passage 9 with eddy flow water inlet pipe 7, have some inlet openings 6 on this passage.
In addition, for ease of scraping off the greasy dirt that rests on the filtrate shelf surface, can have a round mouth near filtrate shelf one side at the top of described filter tank body 10, built-inly are connected the oil removing mechanism that consists of after connecting with skiving blade by pull bar 13, described pull bar 13 can drive skiving blade 3 and slide along the guide rail in the tank body.
The experiment proved that, when using this device and processing the higher sewage of oil-containing quarrel composition, air supporting, hydraulic cyclone and three kinds of modes of self-filtering are well combined, so that filtrate keeps efficient filtration, have the characteristics of oil removal efficiency height, good sewage processing effect.
