Description
Technical field
The utility model belongs to the effluent treatment plant technical field, specifically a kind of jet-pump dissolved air floatation machine of removing greasy dirt and impurity suspended substance.
Background technology
At present, to the purification of sewage and reclaim with utilization be the problems of perceptual interest of people, in oil field, petrochemical complex, refinery, smelting, mechanical workout, coking, printing and dyeing and domestic water, can produce a large amount of sewage, these sewage have not only caused pollution to environment, and taken away a large amount of resources, therefore purify waste water, reclaim resource, the reuse of purifying waste water is the core of efforts at environmental protection.In recent years, the existing multiple flotation machine that is used to dispose of sewage on the market, owing to structurally also there is the imperfection part, the bubble diameter that aerating apparatus produces in the ubiquity machine is desirable not enough.The applicant has applied for " pump formula dissolved air floatation machine " utility model patent, its application number: 02211286.3 on April 18th, 2002.The bubble diameter that the advantage of this structure is to be produced is between the 10-80 micron, and particle diameter is that the interior bubble of 20-30 micrometer range accounts for more than 90% of total amount.But said structure only is applicable to the sewage purification temperature below 50 ℃, and when surpassing 50 ℃, makes air dissolved pump produce serious cavitation, thereby can't normally purify.
Summary of the invention
The purpose of this utility model provides a kind of rational in infrastructure, gas reusable edible that flotation is used and not air-polluting jet-pump dissolved air floatation machine.The sewage purification temperature range that this structure is suitable for is wide, and the bubble diameter that is produced is fit to flotation, but also is specially adapted to the purification of oily(waste)water in the oil field.
The purpose of this utility model is achieved in that it includes the horizontal tank body of front end band sewage import, in tank body, be provided with flotation cell, discharge head, ash pit, hand-hole, be provided with buffer tank in the tank body outside, air dissolved pump, air suction pipe, tank level control water tank, valve, it is characterized in that being provided with the release head in the bottom of flotation cell, discharging head is connected with buffer tank by pipeline, buffer tank is connected with air dissolved pump by pipeline, on air dissolved pump, be connected with a water absorption tube that links to each other with horizontal tank body rear end lower, also be connected with the isocon of a band water sprayer on this water absorption tube and air dissolved pump and the pipeline that buffer tank is connected, air suction pipe is housed on water sprayer; On vertical ash pit of tank interior, be distributed with the transverse row slag chute that is interconnected, the transverse row slag chute is provided with overflow weir, be provided with the dreg scraper of rotation on the top of overflow weir, this dreg scraper is connected with the motor reduction gearbox that is arranged on the horizontal tank external body by transmission shaft; Tank level control water tank is connected with the tank body rear end lower, is provided with purified liquor outlet in the side of this water tank.Its working process is: sewage enters horizontal tank body by the sewage import, through the flotation cell of serial connection, discharged by purified liquor outlet through liquid level control water tank, and realizes purifying purpose again.In flotation cell: start air dissolved pump, the clear water of last flotation cell bottom is in water absorption tube sucks air dissolved pump, air-breathing by water sprayer simultaneously, make and carry out air water in the air dissolved pump and mix, molten gas is by being pumped in the buffer tank; Release head ejection micro-bubble by being arranged on the flotation cell bottom and being diffused in the sewage then, bubble just attaches the surface of elaioleucite and suspended substance in sewage, it is dragged float on the fluid surface, by the dreg scraper that rotates scum silica frost is scraped in the ash pit again.For scum silica frost is flowed in the ash pit smoothly, must utilize liquid level control water tank, water level in the jar is controlled at the overflow weir of ash pit flushes, discharge by the water tank purified liquor outlet after the sewage purification, so move in circles and just can realize the purpose of this utility model.
The purpose of this utility model also is: for the ease of the sediment outflow of horizontal tank base, then be provided with an equally distributed blast pipe in the bottom of tank body inboard, also be provided with the sediment outflow pipe in its bottom.
The purpose of this utility model also is: for the ease of sewage purification or the viscosity bigger sewage purification lower to some temperature, then the bottom of overflow weir is provided with and is convenient to slag liquid mobile heating tube in tank body.
The utility model is owing to be connected with an isocon of being with water sprayer and air suction pipe on water absorption tube and air dissolved pump and pipeline that buffer tank is connected, therefore, air dissolved pump is worked under positive pressure, thereby eliminated the cavitation of pump, the temperature of purifying waste water can be brought up to 80 ℃, enlarge the range of application of this structure, simplified technical process simultaneously.The bubble diameter that the utility model produced is between the 10-80 micron, and particle diameter is that the interior bubble of 20-30 micrometer range accounts for more than 90% of total amount.Owing to be provided with air suction pipe on the water sprayer before pump, water sprayer is pressed into air by air suction pipe and carries out the molten gas first time in the pump, the gas-vapor mix body enters into and carries out the molten gas second time in the buffer tank again, so the bubble of the release head of this structure ejection Duos 30% than the bubble that negative inspiratory pressure produced.Therefore daf efficiency height, it is 40 meters that this structure adopts the air dissolved pump lift, jet flotation machine then adopts 80 meters lift, thus the device specification identical situation under, energy saving is more than 60%.This structure can realize closed operation, to prevent polluted air.Characteristics such as that the utility model also has is rational in infrastructure, some ground area is little, cost is low, remove pollutent efficient height, easy to maintenance, long service life, applied range.
