Description

A kind of decompression air-float purifier
Technical field
The utility model relates to disposing polluted water in oil technical field, is specifically related to a kind of decompression air-float purifier.
Background technology
The oil field sewage that also output is a large amount of while producing crude oil, re-uses after needing to carry out oil removing to sewage.Sewage disposal will through multiple link, and air supporting process is wherein an effective and necessary link.Pneumatically supported principle manages to make to produce a large amount of microbubbles in water, and microbubble rises and sticks to after on removed tiny oil droplets and suspended particle, floats to the water surface, thus make Water warfare because adherend density is less than water.
What oil field was the most frequently used is dissolved air flotation method, it utilizes the characteristic of air different solubility in water under different pressures, pressurization is carried out and aerating to the water of process, increase the meltage of air in water, in normal pressure situation after release, air is separated out and is formed small bubbles in water, and bubble adhesion is on impurity grain, wadding grain global density is less than water and rises, and reaches the object removed from water.The shortcomings such as when disposing of sewage by this mode, a complete set of airfloat equipment needs very large floor space, there is power consumption comparatively large simultaneously, and the noise of air compressor machine is large.
Utility model content
When oil removal by air bubbling being carried out to oilfield sewage for solving in prior art, need that equipment is more, floor space is large, consume energy more technological deficiency, the utility model designs a kind of decompression air-float purifier, the object achieving minimizing equipment, reduce floor space, reduce power consumption, is also applicable to modern enterprise energy-saving and environmental protection simultaneously, subtracts the requirement of consumption, synergy.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of decompression air-float purifier, comprises header and is sleeved on the air supporting pipe in header, is also set with parallel except oil pipe and relief pipe up and down in air supporting pipe; Wherein, air supporting pipe bottom offers posticum along journey, except the top of oil pipe and relief pipe offers receipts oilhole and vent respectively along journey.
Further, relief pipe upper end is provided with water eliminator.
Further, except the oil outlet place of oil pipe tail end is connected with oil-gas mixed delivery pump.
This decompression air-float purifier is the structure of pipe middle sleeve, floor space is little, it is low to consume energy.Adopt liquid to harden stream mode to reduce the pressure in air supporting pipe through the vent of relief pipe and dash, can impel and be dissolved in Sweet natural gas in oilfield sewage and low carbon chain hydro carbons is separated out with the form of micro-bubble, adhere in precipitation process the oil droplet in oilfield sewage, suspended substance emerge together and enter into air supporting pipe top except oil pipe, oil-gas mixed delivery pump is drawn into oil tank; Water pot is flowed automatically to after the posticum of water purification through entering air supporting pipe bottom enters into header.
The beneficial effects of the utility model are: this decompression air-float purifier by utilizing the Sweet natural gas of autolysis, low carbon chain hydro carbons carries out oil removal by air bubbling to sewage, have and reduce investment, save the advantage of electric energy and reduction working cost, be applicable to modern enterprise energy-saving and environmental protection, subtract the requirement of consumption, synergy.

Embodiment
Below in conjunction with accompanying drawing, explanation is explained in detail to structure of the present utility model.
As shown in Figure 1-2, one that the utility model provides decompression air-float purifier, comprises header 1 and is sleeved on the air supporting pipe 2 in header, is also set with parallel except oil pipe 3 and relief pipe 4 up and down in air supporting pipe; Wherein, air supporting pipe bottom offers posticum 21 along journey, except the top of oil pipe and relief pipe offers receipts oilhole 31 and vent 41 respectively along journey.
The one decompression air-float purifier that the utility model provides, relief pipe upper end is provided with water eliminator 5.Except oil outlet 32 place of oil pipe tail end is connected with oil-gas mixed delivery pump.
The one decompression air-float purifier that the utility model provides, takes the mode with valve and microstome throttling, makes liquid pressure before going out relief pipe to remain on 0.1-0.3MPA, make the solution gas in liquid still preserve enough amounts before entering relief pipe; Take to make turnover relief pipe liquid measure relative equilibrium by the mode that pump is taken out, impel the solution gas in liquid to separate out abundant microbubble in air supporting pipe, make emersion liquid level after the bubble adhesion of oil droplet or suspended substance and floating; The water separated uncontrolledly enters into normal pressure water pot by posticum.
The one decompression air-float purifier that the utility model provides, when specifically installing, by the relief pipe import of this device with carry out liquid and be connected, top oil outlet is connected with oil-gas mixed delivery pump and takes out the floating oil-feed tank that is cut, posticum is connected with normal pressure water pot tank of intaking, and inlet flow rate meter and oil and gas multiphase flow pump motor form chain control discharge capacity, make the flow of its in-out apparatus keep balance, the condition that sewage reduces pressure in device can be met, run airfloat equipment and oil removing water purification is carried out to sewage.
The method of a kind of flotation waste water treatment that reduces pressure that the utility model provides, comprises the following steps:
(1), rely on system pressure that oilfield sewage to be processed will be needed to input relief pipe;
(2), start variable-frequency motor, make oil-gas mixed delivery pump and water pump in running order;
(3), water outlet drains into normal pressure water pot, and air supporting overpressure reduces, and Sweet natural gas and the low carbon chain hydro carbons of oilfield sewage autolysis are separated out with the form of micro-bubble;
(4), adhere to the oil droplet in oilfield sewage in Bubble process, suspended substance emerges formation top layer oil slick together;
(5), top layer oil slick enters except oil pipe is drawn into oil tank by oil-gas mixed delivery pump, is drawn into water pot after the water of bottom enters header by water pump.
The square ratio juris of this decompression air-float purifier and decompression flotation waste water treatment is: due to the solubleness of Sweet natural gas in water and air similar, its oleophyllie hydrophobic is also stronger than air; Low carbon chain hydro carbons has been dissolved in oilfield sewage, and the lower low carbon chain hydro carbons of pressure more easily gasifies.As long as ensure that oilfield sewage mineralization pressure falls, be dissolved in Sweet natural gas in oilfield sewage and low carbon chain hydro carbons and namely can the form of bubble separate out.So the method for this decompression flotation waste water treatment adopts throttle style keep pressure and form pressure difference with air supporting pipe before relief pipe, the oilfield sewage that can make to enter air supporting pipe separates out the micro-bubble of q.s, produces larger adhesive attraction and form that floating is cut discharges with the suspended matter in sewage.
It should be noted that, because Sweet natural gas, low carbon chain hydro carbons exploit ground from subterranean oil, gas-bearing formation together with sewage and crude oil, although have passed through the sepn process of oil, gas, water on ground, but all carry out in pressurized vessel because being separated, so still there is a certain amount of solution gas and low carbon chain hydro carbons in oily(waste)water, as long as reduction pressure, they will be separated out with gaseous state, do not need again molten gas.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all do in the utility model flesh and blood any amendment, equivalent to replace and simple modifications etc., all should be included within protection domain of the present utility model.
