Description

The oil-collecting grease trap
Technical field
The utility model relates to a kind of catering trade profit treatment unit.
Background technology
In recent years; growth along with national economy; catering industry develops rapidly; the wastewater flow rate of its discharging is increasing; owing to contain vegetable and animals oils and a large amount of suspended solid of higher concentration in this waste water, make it to become an important water pollution source, the improvement of oily wastewater in catering industry can not only be preserved the ecological environment; and can alleviate the burden at municipal sewage treatment station, have tangible environmental benefit and economic benefit.Containing filth amount is very high in the oily wastewater in catering industry, and principal pollutant are vegetable and animals oils and suspended substance etc.At present, in catering trade, the application of washing composition makes vegetable and animals oils be the emulsification shape and floats in the water, thereby increased the value of chemical oxygen demand in the water greatly, generally all reaches several thousand mg/L; Secondly, because the proportion of vegetable and animals oils and washing composition is less, they and waste water suspension are bonded together, and make it not free settling.This shows that vegetable and animals oils is a key pollutants, the oil-contg that reduces in the oily wastewater in catering industry has direct influence to reducing chemical oxygen demand and suspension content.The use of washing composition makes that vegetable and animals oils is the emulsification shape in the oily wastewater in catering industry, and general profit treatment facility (as oil trap) is difficult to carry out oily water separation, oil in water emulsion must be carried out breakdown of emulsion and handle; Simultaneously, the pasty state because vegetable and animals oils is white in color at normal temperatures, easy blocking pipe when oily water separation has also caused this kind waste water treatment difficulty.
The utility model content
The utility model provides a kind of oil-collecting grease trap, directly handles oily wastewater in catering industry, greasy dirt clearance height, good purification.
Described oil-collecting grease trap comprises the slag removal tank that is communicated with by first pipe connecting and removes fuel tank, oil exit pipe, the oil-collecting bucket, oil exit pipe and slag removal tank, remove fuel tank, the oil-collecting bucket is communicated with, slag removal tank top is equipped with water inlet pipe, the middle part is provided with first oil weir, first oil weir upper end is between the oil exit pipe and first pipe connecting, the height of oil exit pipe is lower than water inlet pipe, remove to be provided with in the fuel tank and squeeze oily device, microbubble generator, second oil weir, the 3rd oil weir and water outlet, squeezing oily device is back taper, be fixed in the oil removing upper box part, microbubble generator is fixed in and squeezes oily device top, and stretch out and squeeze oily device, second oil weir upper end is between the oil exit pipe and first pipe connecting, and the 3rd oil weir upper end is between oil exit pipe and water outlet, and water outlet is communicated with rising pipe.
As improvement of the present utility model, described oil-collecting grease trap also comprises filtered water tank, filtered water tank is removing between fuel tank and the rising pipe, by second pipe connecting with remove the fuel tank water outlet and be communicated with, be provided with the 4th oil weir in the filtered water tank, the upper end of the 4th oil weir is positioned at second pipe connecting top, and rising pipe is located at filtered water tank top, and its feed-water end down.
First oil weir, second oil weir and the 3rd oil weir and the 4th oil weir adopt the conventional design of this area, upper end and side all weld with casing, leave distance between lower end and casing, and water flows through from the below, and oil slick proportion is littler than water, and then being blocked in can not be with drainage flow on the water surface.As optimal way, the lower end of second oil weir and the 3rd oil weir is lower than the lower end of microbubble generator.
Described slag removal tank, remove fuel tank, the filtered water tank bottom is provided with funnel, the funnel lower end is provided with the evacuated tube of belt switch.
As another kind of improvement the of the present utility model, described oil-collecting grease trap also comprises the vapor pipe of being located at slag removal tank, removing fuel tank and filtered water tank top, vapor pipe and slag removal tank, is communicated with except that fuel tank and filtered water tank.
As another kind of improvement the of the present utility model, also comprise the filter residue frame in the described slag removal tank, the filter residue frame is positioned at the water inlet pipe below, and the filter residue frame is preferably made by angle steel and stainless (steel) wire, and top opening, its lap are stainless (steel) wire.
As another kind of improvement the of the present utility model, bypass pipe is installed all on water inlet pipe and the rising pipe.
The catering trade oily(waste)water enters the oil-collecting grease trap by water inlet pipe, and at first process is slag removal tank, and the sewage that contains foreign material and swill enters the filter residue frame, filters out behind the residue of larger particles from enter the slag removal tank main body.Small-particle residue behind the stop certain hour in the sewage is deposited to funnel bottom, and the oil slick major part concentrates on the water surface, then flowed into automatically in the oil-collecting bucket by oil exit pipe when the volume of oil slick increases to the oil exit pipe place, first oil weir can stop that oil slick does not flow into next section with sewage.Can not flow into except that in the fuel tank by pipe connecting with sewage by sedimentary particle; Flow into to remove in the sewage of fuel tank and be mostly small suspended substance and oil in water emulsion, in water, produce a large amount of micro-bubbles by the microbubble generator that removes in the fuel tank, when bubble floating, can take proportion to the sewage surface less than 1.0 the greasy dirt that is dissolved in the water, suspended substance and oil in water emulsion can be attached to bubble surface and emerge along squeezing oily device tapered slope with bubble, form bubble layer at the water surface, because tapered slope is squeezed the existence of oily device, reduced to remove the area of fluid surface in the fuel tank, reduce the greasy dirt burden, thereby bubble layer is raise fast, flow into the oil-collecting bucket from oil exit pipe then, the macrobead suspended substance then is deposited in funnel bottom slightly, and the 3rd oil weir stops that bubble layer enters next section with clear water; Basically become clear water through slag removal tank with the sewage that removes after fuel tank is handled, entered in the filtered water tank again, the back that stays for some time is flowed out by rising pipe and is entered urban pipe network.Evacuated tube is installed in slag removal tank, oil header and filtered water tank lower end, can make things convenient for the workman to keep in repair when encountering problems, simultaneously regularly can emptying scavenger precipitation thing.Vapor pipe can produce sewage in the case and throw out after reaching certain hour peculiar smell and waste gas are discharged, and can reduce peculiar smell to indoor influence.
The utlity model has following advantage:
1) the filter residue frame is made with 5 order stainless (steel) wires, is not easy to be corroded, and is durable in use.
2) microbubble generator produces a large amount of micro-bubbles, and elaioleucite and small suspended substance are fully floated.
3) squeezing oily device makes except that the bubble clc layer of fuel tank and in time discharges.
4) slag removal tank, oil header, filtered water tank bottom are provided with funnel, make things convenient for throw out and sewage in the emptying case, are convenient to maintenance and maintenance.
5) reasonable, the organic assembling of whole device various piece.
The comprehensive current domestic and international sewage disposal technology of the utility model, new-type air supporting method is cooperated with oil trap, directly handle oily wastewater in catering industry, greasy dirt clearance height, can reach about 92%, good purification, the sewage after the processing can reach national secondary discharge standard, can directly be discharged to municipal sewage pipe network.
