Abstract

The utility model relates to an oil removing device in sewage treatment. The oil removing device comprises a casing, an ultrasonic emulsion breaking chamber and an air supporting separation chamber, wherein an air inlet pipe, a water inlet pipe, an air-dissolved water inlet, a water outlet pipe, an oil outlet and pollution discharging ports are arranged on the casing, the ultrasonic emulsion breaking chamber and the air supporting separation chamber are formed by being separated by a plurality of baffle plates, and at least two ultrasonic generators are arranged in the ultrasonic emulsion breaking chamber. The oil removing device is characterized in that a separating plate is arranged in the ultrasonic emulsion breaking chamber, and separates at least two ultrasonic generators, and the ultrasonic generators are arranged between 1/4 and 1/2 of the bottom of the ultrasonic emulsion breaking chamber; the water outlet pipe is arranged at the lower part of the air supporting separation chamber, and the water inlet pipe is introduced from the lower part of the ultrasonic emulsion breaking chamber, and the water outlet pipe is positioned at the water outlet at the lower part of the air supporting separation chamber. The oil removing device has the advantages of simple structure, high efficiency of oil removal and low running cost.

Description

The sewage disposal oil removal plant
Technical field
The utility model belongs to sewage treatment facility, is specifically related to a kind of sewage disposal oil removal plant.
Background technology
Publication number is that CN2719375 discloses " a kind of smelting industry extraction oil removing dedicated system ", this dedicated system belongs to the oily water separation field, comprise grease trap, the breaking milk and removing oil device, strainer, grease trap is the constant current mode grease trap, and the breaking milk and removing oil device is a ultrasonic wave air supporting oil eliminator, and strainer is a fiber ball filter, pipeline connection successively before and after three equipment, this utility model adopts the ultrasonic dehydration degreasing technique, in conjunction with oil removal and filtration oil removing, can not introduce new impurity and suspended substance, pollution-free, energy consumption is low, oil removal efficiency height, organic rate of recovery height, simple to operate, equipment operation maintenance is convenient, and can realize automatization control, need not the special messenger and keeps an eye on.But, more than two patents have following shortcoming: produce stack or focus between indoor two ultrasonic wave of breakdown of emulsion, intensity is wayward, even can cause the second emulsifying of processed liquid; Ultrasonic demulsifier is installed in the bottom, and ultrasonic waves transmitted is reflected by the chamber wall, causes the stack with reflection wave, influences demulsification; Owing to adopt pneumatic ultrasonic wave, make having returned of bottom settlings thing, influence deoiling effect.
Summary of the invention
A kind of sewage disposal oil removal plant that the utility model aims to provide is simple in structure, oil removal efficiency is high and running cost is low.
The utility model is put and is comprised housing, the ultrasonic dehydration chamber, air flotation separating chamber, housing is provided with inlet pipe, water inlet pipe, the dissolved air water import, rising pipe, oil outlet, sewage draining exit, the ultrasonic dehydration chamber, air flotation separating chamber is made of some dividing plates separations, the ultrasonic dehydration chamber is provided with at least two ultrasonic generators, it is characterized in that described ultrasonic dehydration chamber is provided with division board, this division board is separated at least two ultrasonic generators, ultrasonic generator is arranged on apart between the 1/4-1/2 of bottom, ultrasonic dehydration chamber, rising pipe is arranged on the bottom of air flotation separating chamber, water inlet pipe feeds from the bottom of ultrasonic dehydration chamber, and rising pipe is positioned at the water outlet of air flotation separating chamber bottom.
The utility model combines ultrasonic wave and air supporting, finishes breakdown of emulsion and separates: when ultrasonic wave acts on oily(waste)water, make elaioleucite produce vibration, collision mutually becomes original small elaioleucite adhesion into macrobead, thereby reaches the purpose of breakdown of emulsion; Oil-containing water behind ultrasonic dehydration enters air-floating apparatus, adopt traditional efficient dissolved air release, in water, produce the trickle bubble of sufficient amount, with the adhesion mutually of suspension elaioleucite, form global density " gas-oil " complex body less than water-mass density, rise to the top together, then draw, finish separation from the gas-floating chamber bottom through the water of oil removing.The utility model is simple in structure, the oil removal efficiency height, the ultrasonic dehydration chamber is provided with independently ultrasonic dehydration chamber, form two independently ultrasonic wave zone of action, increase the distance of ultrasonic generator and bottom simultaneously, reduced the hyperacoustic reflection in bottom, the second emulsifying problem that has thoroughly solved phase mutual interference and the stack between the ultrasonic wave and caused processed solution, outlet system is installed in the bottom of air flotation separating chamber, makes separating flowing field more even, easily, energy consumption is low, simple to operate, equipment operation maintenance is convenient, and running cost is low, can not produce by adding the secondary pollution that emulsion splitter causes.

Fig. 2 is the vertical view of Fig. 1.
Among the figure, 1, housing, 2, the ultrasonic dehydration chamber, 3, air flotation separating chamber, 4, tracheae 4,5, water inlet pipe, 61 dividing plates, 62 dividing plates, 63, dividing plate, 7, oil outlet, 8, rising pipe, 9, division board, 10, the dissolved air water import, 11, sewage draining exit, 12, ultrasonic generator.
Embodiment
Embodiment: Fig. 1, shown in Figure 2, present embodiment comprises housing 1, ultrasonic dehydration chamber 2, air flotation separating chamber 3, described housing 1 is provided with inlet pipe 4, water inlet pipe 5, dissolved air water import 10, rising pipe 8, oil outlet 7, sewage draining exit 11, described ultrasonic dehydration chamber 2, air flotation separating chamber 3 is by three dividing plates 61,62,63 separate formation, described water inlet pipe 5 feeds from the bottom of ultrasonic dehydration chamber 2, described rising pipe 8 is arranged on the bottom of air flotation separating chamber 3, the part that is positioned at air flotation separating chamber 3 bottoms of rising pipe 8 comprises a plurality of equally distributed water outlets 13, described ultrasonic dehydration chamber 2 is provided with two ultrasonic generators 12, these two ultrasonic generators 12 comprise the oscillator with sheet metal, ultrasonic generator 12 is arranged on 1/4 place, 2 bottoms apart from the ultrasonic dehydration chamber, described ultrasonic dehydration chamber 2 is provided with division board 9, the height of this division board 9 is 1/2 of ultrasonic dehydration chamber 2 interior outage degree, and two ultrasonic generators 12 are separated.
The ultrasonic generator 12 of present embodiment is one to have the oscillator of sheet metal, the air-flow that adopts pressurized air to quicken to reach velocity of sound through nozzle blows the sheet metal of vibrator, make sheet metal on its natural frequency, produce the intensive ultrasonic vibration, elaioleucite is collided mutually, adhesion, and from water, resolve, separate, simultaneously, ultrasonic generator is installed between the 1/4-1/2 of bottom, breakdown of emulsion chamber, separate with dividing plate between the ultrasonic generator, solve ultrasonic wave at the reflection of bottom and the overlaying influence between the ultrasonic wave, outlet system is installed in the bottom of gas-floating chamber, makes separating flowing field more even, easily.
