Description
Technical field
The present invention relates to mud dehydration plant, and in particular to it is a kind of based on mud transport pipeline to the interval of flowable state mud
Water outlet apparatus for electrodewatering.
Background technology
Mud refers to be deposited in hydrostatic or slow flowing water environment, being formed through physical chemistry and biological chemistry action,
Unconsolidated weak particulate or superfine particle soil.Processing method in industry to mud mainly takes the mode of heap mud, typically
It is natural air drying, but the method floor space is big, and dewatering time is long, is also easy to produce secondary pollution, and dehydrating effect is also not satisfactory.
Solid material, due to there is the effect such as ionization or ionic adsorption, makes its table on the interface being in contact with polar water
Face carries positive electricity or negative electricity.Charging point forms electric double layer with the counter ion in liquid.In the presence of electric field, in diffusion layer
Counter ion carry moisture to electrode movement, form electro-osmosis phenomenon.Dividing for solidliquid mixture can be realized using electro-osmosis phenomenon
From especially for colloid material, mechanical dehydration method effect on driving birds is not good, and electroosmotic dewatering technology has preferably dehydration effect
Really.
The electric dehydration technology for having developed at present is typically with vertical electric field carries out electric dehydration to mud, on positive plate
Side applies pressure, forms pressurization electric dehydration process.But the mud for being in the duct flowable state carries out the research base of electric dehydration
This is in space state.Electric dehydration is carried out by the mud during flowing, it is possible to reduce the step of sludge dewatering and the time,
Unnecessary place spending is reduced, the optimization of disposal benefit purpose is realized.
The content of the invention
Goal of the invention：For the problem that prior art is present, the present invention provides a kind of interval based on mud transport pipeline

Substantially, apart from too short, the sphere of action of electric field is too narrow.
Further, the enters mud pipe, angle is 0~90 ° and can adjust between sludge out pipe and reaction tube.As giving
Drainage arrangement, reduce the loss of flood peak be it is highly important, by adjust the angle between enters mud pipe and sludge out pipe and reaction tube come
The water reduced in mud course of conveying is damaged.
The side of the reaction tube is additionally provided with relief tube, and the second relief valve is provided with relief tube.On relief tube
It is excessive that two relief valves play anti-locking apparatus internal pressure, the purpose of protection device.
The pressure release value of second relief valve is more than the pressure release value of the first relief valve, and the pressure release value of two relief valves is respectively less than
The carrying pressure value of device.The purpose of the first relief valve is to make device interval water outlet, and the purpose of the second relief valve is protection device
Do not explode, the pressure release value of the first relief valve needs the pressure release value less than the second relief valve, and the both less than carrying pressure of device.
Further, the anode electrode and cathode electrode are respectively by the anode wire through reaction tube and negative electrode electric wire
It is connected with the both positive and negative polarity of external power supply.
Further, the apparatus for electrodewatering outer wall material is insulating materials.Each critical piece can be with dismounting and change.
Operation principle：Before taking out mud, device is put up, by the both positive and negative polarity phase of anode electrode and cathode electrode and external power supply
Even, device is built and finishes rear check device with the presence or absence of drainage.When taking out mud, sludge pump will contain water slurry and extract out and be input into pipe
Road, passes sequentially through region and sludge out pipe between enters mud pipe, reaction tube Anodic electrode and cathode electrode.When the pressure in device not
When reaching the pressure value of the first relief valve on sludge out pipe, the first relief valve on sludge out pipe is closed, containing water slurry not
It is disconnected to enter device, the pressure in device is gradually increased until reaching the pressure value of the first relief valve on sludge out pipe, open it
Open, mud flows out from sludge out pipe.It is wherein defeated to reduce mud by adjusting the angle between enters mud pipe and sludge out pipe and reaction tube
Water during sending is damaged.Combination water and Free water in mud are subject to electric field, internal pressure, gravity between anodic-cathodic in a device
Multiple action, deviate from and by mesh cathode electrode from drainpipe discharge.The second relief valve on relief tube is played prevents dress
Put that internal pressure is excessive, the purpose of protection device.
Beneficial effect：Compared with prior art, the invention has the advantages that：
1st, apparatus for electrodewatering of the present invention is realized carries out electric dehydration to the mud flowed in pipeline, in alleviating dehydration
Dependence to place, saves dewatering time；And can realize that supercharging accelerates dehydration, interval effluent functions.
2nd, apparatus for electrodewatering of the invention is carried out to mud-water separation, using interval water outlet, short time high pressure is provided to device,
Improve water separation capability.
3rd, dewatering efficiency of the present invention is high, compared to conventional dehydration technique, enhances the removal to the combination water in mud.
4th, simple structure of the present invention, its critical piece is detachable, has preferable compatibility with existing equipment, profit
In production application.
