Description
Technical field
The invention belongs to the environmental protection equipment field, relate to oil skimmer, specifically, provide a kind of device that is used to collect oil slick
Background technology
At present known various floating oil collecting devices and technical scheme are a lot, can be divided into several types such as medium absorption type, water conservancy diversion shovel modus ponens, overflow collecting type substantially in form.Wherein the overflow collecting type is to adopt open containers to bubble through the water column, and utilizes draining to make the inside and outside formation of container liquid level poor, and oil slick is collected in the outer liquid level overflow in container of container.It is generally acknowledged that the efficient with overflow current collection mode collection oil slick should be very high, but, make it collect performance and limited to because at present known various devices and technical scheme with overflow current collection mode collection oil slick come with some shortcomings.
(application number: 92209302.4) efficient to floating oil collecting has given great attention to the utility model patent document, has adopted the overflow current collection mode.This utility model adopts open-top receptacle to bubble through the water column, and top edge is a little less than the water surface, and it is poor that the startup suction pump forms inside and outside liquid level, and the water of oil-containing is flowed in the open-top receptacle.Container can rise when this scheme had been noticed in the container drawdown, and the difference in height of container upper limb and the water surface can change, and profit flows into layer rising meeting attenuation along with container, enters flow and diminishes.Under the certain situation of drain discharge, enter flow and be lower than delivery flow, water level continues to descend in the container, causes container to continue to rise again, at last can't steady operation.The thickness that flows into layer when profit is bigger, and when surpassing drain discharge, liquid level rising container sinks in the container, makes profit flow into layer thickness and more strengthens, and it is bigger to enter flow, and container continues to sink, and also can't work at last.Although the inventor has adopted modes such as liquid-level switch, electrical equipment control to control the interior liquid level of container, can imagine that such course of work is to be difficult to continuous high-efficient.
Utility model (application number: 962248150) technical scheme that is proposed and utility model (application number: 92209302.4) have the same deficiency, although this scheme does not solve root problem having considered finer solution aspect the control liquid level.
Summary of the invention
The object of the invention aims to provide a kind of simple in structure, energy consumption is lower, collection efficiency significantly improves, combination property is outstanding excellent device that is used to collect oil slick.
In general, floating oil collecting equipment should comprise that floating oil collecting device, oil content extract conveying device, oil content storage device, electrical control gear and other functional ancillary facility.For outstanding theme of the present invention, only the floating oil collecting device that the present invention relates to is illustrated herein, other device and facility will not be given unnecessary details.
Floating oil collecting device involved in the present invention is made up of current-collecting device and dewatering installation.Wherein current-collecting device by surge drum, buoyancy aid and be based upon surge drum and buoyancy aid between the ring packing structure form.There is the space that communicates with the water surface that does not have upstream face that surge drum can be packed among the said buoyancy aid, relative displacement is up and down done with respect to buoyancy aid after allowing surge drum to pack in this space, and have and allow the surge drum height of certain depth under water that submerges, around this space or bottom surface has at least sets up a kind of ring packing structure that allows surge drum to do upper and lower displacement with respect to buoyancy aid between a plane or regular curved surface and the surge drum, buoyancy aid upper limb some (high terrace) around this space surfaces all the time, make float and use buoyant equilibrium when regulating liquid level change in the surge drum, some (end terrace) the inflow surge drum that is lower than the water surface all the time so that liquid level communicates.Lower edge opening on its cylindrical shell of said surge drum, can independently bubble through the water column and make the upper limb opening surface to protrude the water surface, the surge drum upper limb is lower than the water surface because of buoyancy (the hydrostatic pressure sum that refers to the vertical water surface, above-below direction) minimizing in the time of can making in the surge drum liquid level be lower than the outer liquid level certain altitude of tube by negative pressure, the overflow of the outer oil slick layer of tube collected to surge drum, surge drum lower edge opening, make the surge drum inner core by forming the cavity (for sake of convenience, the back all is referred to as collecting chamber to this cavity) hold the profit that afflux comes between ring packing structure and the buoyancy aid.The said ring packing structure of setting up between surge drum and buoyancy aid had both allowed surge drum to do upper and lower displacement with respect to buoyancy aid, can stop again or confined liquid flows into collecting chamber from the space between surge drum and the buoyancy aid.Collecting chamber is communicated with drainage system, and dewatering installation can directly be communicated with the water body outside the buoyancy aid, also can be discharged into other places through closed conduit.
Operating principle:
This device is put into water, and the high terrace of buoyancy aid upper limb is bubbled through the water column, and collecting chamber at first is in anhydrous state, and surge drum is in low level because of gravity greater than buoyancy, and its upper limb is lower than the water surface, can flow through buoyancy aid and go into collecting chamber through surge drum upper limb afflux of water surface oil-water-layer.At this moment, the injecting process of this device has following two kinds of differences owing to the sealing performance of the form of dewatering installation and hermetically-sealed construction is different: if 1. dewatering installation can not return and irritates and hermetically-sealed construction does not have leakage, oil-water-layer can only flow into collecting chamber from the surge drum upper limb.Along with the water level in the surge drum raises gradually, the buoyancy that surge drum is subjected to is increasing, and the surge drum come-up is concordant with extraneous liquid level until upper limb, and extraneous oil-water-layer stops to flow into, and this moment, the collecting chamber liquid level was lower than water surface maintenance static balancing; 2. if surge drum exists leakage or drainage system to be communicated with the outer water body of buoyancy aid with hermetically-sealed construction between the buoyancy aid can to return filling, liquid level can continue to raise in the surge drum, surge drum increases, when liquid level in the surge drum reaches extraneous liquid level when concordant owing to leaking or return to irritate, on the surge drum upper limb is bubbled through the water column, be in nature emersion state, liquid level inside and outside the surge drum is separated and keep static balancing.As seen, because the form of dewatering installation is different with the sealing performance of hermetically-sealed construction, the present invention can produce the static balancing of two kinds of diverse locations in the injecting process, but they any is arranged is identical: the liquid level in the surge drum when being in static balancing separates with extraneous liquid level all the time.Utilize this performance, can make the oil slick that enters surge drum not return the extraneous water surface and get on.
During operate as normal, dewatering installation starts, and the moisture of collecting chamber bottom is discharged through dewatering installation, and the collecting chamber liquid level descends, and surge drum descends because of buoyancy diminishes thereupon, and when the surge drum upper limb is lower than the water surface, oil-water-layer begins to flow into surge drum.When just beginning, surge drum decline displacement is little, and it is little that profit flows into layer thickness, and the inflow flow is less than drain discharge, and liquid level continues to descend in the surge drum, and surge drum is also along with continuing decline.The surge drum upper limb continues to increase apart from the discrepancy in elevation (flow-guiding mouth) of extraneous liquid level, and profit flows into layer thickness thickening thereupon.Be increased to and can satisfy when flowing into flow and delivery flow and reaching balance when profit flows into layer thickness, surge drum and collecting chamber liquid level no longer descend, and reach steady-working state.The balance of this moment is called dynamic equilibrium.
When factor affecting such as being subjected to Flow-rate adjustment, wave causes entering or delivery flow when changing, as follows to the impact analysis that dynamic equilibrium produced: 1. as to turn down or wave wave peak pours in when delivery flow, enter flow greater than delivery flow, the collecting chamber liquid level rises, surge drum rises, profit flows into layer thickness and diminishes, and enters flow and diminishes, until reaching new dynamic equilibrium; 2. big or run into wave wave paddy when the discharge currents quantitative change, enter flow less than delivery flow, the collecting chamber liquid level descends, and surge drum descends, and profit flows into layer thickness and becomes big, enters flow and becomes big, until reaching new dynamic equilibrium.
The overflow collecting type container of prior art generally all is to rise and container descends along with liquid level in the container, along with liquid level in the container descends and container rises, keep desirable duty very difficult.The present invention gives buoyancy aid by telescopic ring packing structure with the buoyancy variation that liquid level change produced in the collecting chamber and bears, buoyancy aid rises and descends, rises with its decline along with liquid level in the collecting chamber, and surge drum is opposite, surge drum is that surge drum rises along with the rising of liquid level in the tube, and liquid level descends and surge drum decline.Because this distinct performance has been arranged, make the surge drum among the present invention have the ability of self-seeking balance, when not being worked, it keeps static balancing all the time, keep dynamic equilibrium during work all the time.
The present invention can move entirely continuously, does not need to adjust draft, does not need intermitten service to obtain normal operating conditions, can continuously oil-water-layer be imported, and oil slick gathers on collecting chamber top, extracts through other facility then and shifts.
In various Rational Parameters, under the certain situation of delivery flow, it is certain that profit flows into layer thickness, by regulating delivery flow (as passing through variable frequency regulating speed control), can obtain different profits and flow into layer thickness, make it to adapt, can improve the oil-containing ratio of the oil-water-layer that enters collecting chamber as much as possible with the oil slick layer of continuous attenuation in collection process.Energy consumption that can be lower obtains higher collecting effect.
After equipment shut down, the collecting chamber liquid level was got back to the static balancing position, and oil slick still cuts off outward with tube in the surge drum.If the dewatering installation outlet is higher than the water surface, can on drainage channel, establishes flap valve and prevent to pour in down a chimney.
