Description

The sewer oil tripping device

Technical field

The present invention relates to a kind of oily water separating equipment, relate in particular to the tripping device that a kind of sewer oil is recycled.

Background technology

The collection of tradition sewer oil is artificial collection the in the floating back of long sedimentation choosing through multistage oil sump, has the problem that efficient is low, work is loaded down with trivial details and environment is abominable.

Summary of the invention

In order to overcome the above-mentioned shortcoming of prior art; The present invention provides the shallow pond of a kind of employing sedimentation theory, rotational flow separation principle and wetting coalescence principle and swash plate oil removing; Improved the release surface that the unit pond holds, the sewer oil tripping device that the effect of oily water separation is improved.

The present invention solves the technological method that its technical problem adopts: a kind of sewer oil tripping device, and equalizing tank is arranged, remove oil tank and connecting pipeline, said equalizing tank bottom is provided with the funnel-form combustion chamber hopper, in the bottom of funnel-form combustion chamber hopper wash water valve is installed; Pressure controlled valve and greasy dirt water pipe are installed in the equalizing tank bottom, have buoyancy aid to enter the mouth in the inner of greasy dirt water pipe through hose connection, said greasy dirt water pipe outer end is equipped with valve and pipeline, and this pipeline and the above-mentioned oily water inlet that removes tank bottom join; Said sewage inlet communicates with the swirler-that is installed in except that on the interior jar in the inner chamber of oil tank through pipeline; Interior jar of periphery and except that between the oil tank internal chamber wall swash plate oil eliminator is installed, said interior pot bottom is provided with and pushes back water inlet, and said interior jar top is provided with water port; This water port connecting pipeline passes except that oil tank body and communicates with the outside; Said top of removing oil tank is provided with overflow groove, is provided with oil discharge outlet in isopipe root, and said bottom of removing oil tank is provided with sludge discharging port.

Said funnel-form combustion chamber hopper inclined-plane angle is 45 degree.

The invention has the beneficial effects as follows: the liquid level difference of utilizing effluent stream when device, to form, realize oily water separation, can shorten retention time of sewage, reduced volume of equipment, oil-water separation is good, and floor space is little, and pure Machine Design is simple in structure, good stability.

The present invention need not add any reagent and medicine in production technique, non-secondary pollution, and installation and maintenance are simple and convenient; Just can use as long as connect water inlet pipe, rising pipe, need not special messenger's during-operation service, only need that regularly receipts are oily gets final product; Be applicable to all oil kinds; The high more effect of oil-feed concentration is good more, is applicable in the wastewater treatment that contains natural oil and petroleum products, tar and tar fraction, plant-animal wet goods, is specially adapted to the processing of catering oily(waste)water.

Embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is further specified.

Referring to Fig. 1; A kind of sewer oil tripping device has equalizing tank 1, removes oil tank 2 and connecting pipeline 3, and said equalizing tank bottom is provided with funnel-form combustion chamber hopper 4; In the bottom of each funnel-form combustion chamber hopper 4 wash water valve 5 is installed; Constituting funnel-form combustion chamber hopper 4 by miter angle, be easy to so on the one hand clean, is to prevent that the turbulent flow of current from bringing a large amount of slag things such as silt into the treatment facility of postorder on the other hand; Pressure controlled valve 6 and greasy dirt water pipe 7 are installed in equalizing tank 1 bottom; Pressure controlled valve 6 can be stablized liquid level; The treatment facility that moves the water to flow into postorder obtains one and is unlikely to too big flow; In order to avoid surpass the processing power of postorder equipment, also accomplish to have when the same day, discharge capacity was especially big simultaneously the effect of sluicing; The inner of said greasy dirt water pipe 7 is connected with buoyancy aid inlet 9 through flexible pipe 8, no matter oily water water level height, buoyancy aid inlet 9 remains at the oily water the superiors, so that absorb the oily water on upper strata better; Said greasy dirt water pipe 7 outer ends are equipped with valve 10 and are connected with pipeline 3, and water valve 10 wherein plays the effect of cutting out current.Just can close current and operate when the postorder treatment facility will clean, keeps in repair or change component etc.; Pipeline 3 wherein joins with the above-mentioned oily water inlet 11 that removes oil tank 2 bottoms; Said oily water inlet 11 communicates with the swirler-13 that is installed in except that on the interior jar 12 in the inner chamber of oil tank 2 through pipeline 3, when oily(waste)water flows out from swirler-13 water outlet tangentials, in jar, forms eddy current; At this moment oil slick is easy to owing to float to oil reservoir in the effect at first of density difference in the water, and particle diameter is not very big can arrive oil reservoir faster by the component velocity on the current direction yet, and is integral with oil reservoir is sticking; The less elaioleucite of part particle diameter when its volume during less than 80～100 μ m the elaioleucite ascent rate very slow, even do not have the ability come-up, this a part of elaioleucite in the effect of the centripetal force of the current generation of vortex constantly to site polymerization; Elaioleucite all toward the central motion time each other each other the probability of collision improve greatly, constantly collision coalescence becomes big elaioleucite and floats, and can adsorb at outer wall (lipophilic material) moistened surface of inner chamber by the oil droplet of centripetal force effect; Material surface is almost encased by oil like this; Up to saturated, more next also easier wetting adhering to from the teeth outwards of oil droplet of stream, the continuous coalescence of the oil droplet that adheres to enlarges; And formation oil film; Form oil droplet in the water because the effect of buoyancy and water impact, oil film begin to be shed to, float in the oil reservoir on automatic; This oleophilicity material can be acrylic plastering, " the wetting coalescence " used always on the petroleum industry that Here it is; Jar 12 peripheries are equipped with swash plate oil eliminator 14 with removing between the oil tank internal chamber wall in said, and it belongs to the oil removing of physics method swash plate oil eliminator 14, is that a kind of gravity separation is technological.Gravitational separation process is handled oily(waste)water, is different with the density of water according to oil, utilizes the density official post oil come-up of oil and water, reaches the oily water separation purpose.Jar 12 bottoms are provided with and push back water 15 inlets in said; Jar 14 tops are provided with water port 16 in said; These water port 16 connecting pipelines pass except that oil tank 2 tank bodies and communicate with the outside, and said top of removing oil tank 2 is provided with overflow groove 17, is provided with oil discharge outlet 18 in overflow groove 17 bottoms.As shown in the figure, in removing oil tank 2 through the innage after the oily water separation during in overflow weir just from oil discharge outlet 18 outflows of overflow groove 17; Sewage after the separation through interior pot bottom push back water inlet get in jar in outside the water port tank body, said bottom except that oil tank is provided with sludge discharging port 19.

The present invention is that a kind of efficient is high, energy consumption is low, cost, the simple sewer oil separated and collected of technology device; Whole device mainly is divided into equalizing tank, removes two parts of oil tank; Collecting the back is purchased by special acquiring company; Can sewer oil be transformed into biofuel efficiently, not only effectively alleviate the pressure of oil shortage, biofuel acts as a fuel and also reduces the pollution to air.
