Description
Technical field
The utility model belongs to oil field hydraulic fracturing equipment technical field, is related to a kind of portable dissolved air floatation device, energy
It is enough to go down except the objectionable impurities in sewage in surface conditions, sewage is re-used.
Background technology
Hydraulic fracturing technology is a kind of effective well stimulation for obtaining high production capacity shale gas well, is needed in work progress continuous
The a large amount of fracturing fluids of infusion, individual well can consume all places clear water.Preparing fracturing fluid needs to use high performance chemical agent, chemical agent with it is clear
Water mixed preparing fracturing fluid cost is relatively low, and yet with shortage of water resources, Gas Company has to select to use hydraulic fracturing anti-
Draining carrys out preparing fracturing fluid.Anti- draining or recovered water are the water produced from producing well, the water of usual producing well early stage output
Impurity content is less, and the water in this stage can be used to substitute clear water preparing fracturing fluid.
Anti- draining in early days is but impurity therein or suspended solid meeting most beneficial for the part of preparing fracturing fluid in anti-draining
Cause many problems, it is similar with ion and bacterium, cause oil-production capacity to reduce.Because water quality is poor, ground and underground equipment are logical
Fouling and blocking often can occur.
Hydraulic fracturing is usually used clear water preparing fracturing fluid, and the suspended solid that down-hole formation basement rock is produced can be dissolved in pressure
In splitting liquid.Suspended solid can be precipitated when anti-draining is re-used, and can also reduce the efficiency of oil-gas field fracturing chemical agent.
Therefore, the problem that suspended solid is that anti-draining re-uses overriding concern is removed.Introduce mechanical filtration systems or other energy are close
Collection type method is come to eliminate SS be very expensive, and chemical flocculation is that a kind of cost is relatively low, high treating effect
Sewage disposal means, but problem is how to design a mobile sewage treatment apparatus, in order to adapt to the resettlement of pressure break scene
Frequently environment.Solving this problem needs to expend substantial contribution, and needs rational design.
The utility model can solve the deficiency that anti-draining is re-used by a kind of portable dissolved air floatation device of design
Part, reduces hydraulic fracturing construction cost.
Utility model content
The purpose of this utility model is to provide a kind of portable dissolved air floatation device, eliminates anti-draining in hydraulic fracturing process
In SS, be that anti-draining is re-used and created conditions.The purpose of this utility model is real by the following technical programs
It is existing.
A kind of portable dissolved air floatation device, including following part：Tank, the mobile device, flocculant outside tank adds
Feeder apparatus, water inlet, air inlet in tank, delivery port, agitating device, and flocculate collection device, it is characterised in that water
Cofferdam is additionally provided with groove.The solid particulate matter flocculating setting in anti-draining is made by the way of addition flocculant, gas is then passed to
Body, makes floc particles stick on bubble, and with bubble the water surface is floated to, and forms foam --- and gas and water, particle three-phase are mixed
Zoarium, by collecting flocculate the purpose for separating impurity, purifying anti-draining is reached.This purification technique, is that a kind of cost is reasonable
Sewage disposal means.But for mobile cleaning device, problem is to mix more difficult and time sensitivity is strong.Therefore, move
Dynamic formula dissolved air floatation device needs well-designed apparatus structure, flocculates in accurate time point when passing through device in order to water
Sedimentation.By designing cofferdam in tank, the processing speed of anti-draining can be accurately controlled, so as to meet the energy of different parts
Power.
Further, the cofferdam is provided with displacement mechanism and height adjustment mechanism.Machine is adjusted by displacement mechanism and height
Structure, thus it is possible to vary the position in cofferdam and height, can adapt to the anti-draining of change of water quality, improves cleaning fluid and contains trash flow
The separative efficiency of body.
Further, the cofferdam has multiple.
Further, flocculate spread device is additionally provided with tank.Flocculate spread device can make flocculate horizontal homogeneous point
Cloth, it is to avoid water body is again introduced into after local accumulation.
Further, the flocculate collection device includes scraper plate and flocculate collecting pit, and scraper plate is by the wadding kept afloat
Condensate is scraped into flocculate collecting pit.
Further, the flocculant adding apparatus are provided with meter and timer, can be accurate according to setting time interval
Really add flocculant.
The workflow of the portable dissolved air floatation device that the utility model is provided is as follows：
Anti- draining is entered in tank by water inlet, is accurately added according to setting time interval by flocculant adding apparatus
There is particle flocculation after mixing with anti-draining under the stirring action of agitating device in flocculant, flocculant, compressed air pass through into
Bubble is formed in gas port injection screw clamp, coagulated particles is carried and is risen to the surface, fluid flows through cofferdam makes cleaning fluid and containing miscellaneous
The fluid of matter is separated, and the powder collection for rising to the surface, the water after purification are discharged to tank car by flocculate collection device from delivery port
Or secondary filter system.Mobile device is provided with outside tank, anti-drainage sunk well position can be as needed moved to.
The portable dissolved air floatation device that the utility model is provided predominantly processes the design of oil gas field sewage, can improve page
Rock gas well yield, and sewage disposal can be carried out with relatively low cost.The anti-draining of hydraulic fracturing through processing, to fracturing fluid and
The harmful impurity of fractured well Production Life is removed, recyclable to prepare more fracturing fluids.The flocculated suspension solid for floatingly selecting can
To serve as the pre-filtrating equipment of dissolved solid, contribute to these impurity and removed by reverse osmosis.Anti- draining after treatment, can be with
The blocking and fouling of fracturing unit and gas pay are prevented, it is cost-effective.
