Description
Technical field
The utility model relates to a kind of pulse cycle electrolytic gas floating waste disposal plant.
Background technology
The air supporting method is solid-liquid or isolating a kind of method of liquid-liquid, it is by producing a large amount of microbubbles someway in water, the solid or the liquid particle that make density in itself and the water approach water adhere to, and the air float body of formation floats to the water surface and consolidate-liquid or liquid-liquid separation under buoyancy function.It is very effective to oils, fiber, suspended solids, algae, active sludge or microbial film etc. that separation proportion approaches water.According to the mode that microbubble produces, the air supporting method can be divided into three kinds of electrolytic gas float glass process, the gas air supporting method of loosing and dissolved air flotations, and the pressurized dissolved air flotation method is the most commonly used.In the air dissolving system of the pressurized dissolved air flotation that adopts, generally adopt the air dissolving system of air compressor machine-dissolving or ejector-dissolving at present.It has the following disadvantages: (1) is because dissolving inconvenience control causes the air flotation effect instability; (2) conventional reliever easily is recycled particle plugging in the water in gas releasing system; (3) microbubble of Chan Shenging big (mean diameter is greater than 40 μ m) influences treatment effect; (4) bubble and suspension dirt are shorter duration of contact, and the adhesion effect of bubble is relatively poor, has reduced effluent quality.And the electrolytic gas float glass process has that microbubble is little, density big, high treating effect, but has the following disadvantages: (1) electric energy consumption is high and be difficult to apply; (2) the fast and passivation of the easy loss of electrode can not be satisfied actual application; (3) the flow velocity gradient is not enough in the electrolytic gas floating chamber, does not reach the required optimal hydraulic conditions of coagulation, and the forming process of flocs unit is slower, influences treatment effect.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, a kind of pulse cycle power supply mode, microbubble is little, energy consumption is low electrolytic gas floating waste disposal plant of adopting is provided, it comprises electrolytic gas floating chamber, intake chamber, filter screen, water-in, pulse cycle electric supply installation, water-supplying chamber and electrode group, it is characterized in that described electrolytic gas floating chamber is deflector type electrolytic gas floating chamber, be provided with the electrode group of deflector type electrode anchor and sectional type multiple electrode structure in deflector type electrolytic gas floating chamber, its electrode group is convex-concave shape or uniform W shape structure; The electrode group is to place on the electrode anchor.Electrode group low and low-cost Stainless Steel Cloth anode and graphite material are made by overpotential negative electrode and electrode partition are formed, and its electrode pad is apart from being 1.8mm～2.5mm.
Described pulse cycle electric supply installation is a sectional type recurrence interval property circulating power supply device, and it is made up of leakage field protection powerstat, rectifier, stabilizing inducatnce gate-controlled switch group, programmable logic controller and electrode group.Its gate-controlled switch group is added on the electrode group, and the programmable logic controller the utility model that links to each other with the gate-controlled switch group adopts segmentation or multi-electrode recurrence interval cycle power mode.
The utility model is a kind of novel electrofloatation water treatment method and device, is used for various Industrial Wastewater Treatment such as pharmacy, printing and dyeing, papermaking, chemical industry, also can transform traditional air supporting treatment unit.
The new reason of this practicality compared with prior art has the following advantages:
(1) the microbubble density of electrolysis generation is big, bubble diameter little (mean diameter is less than 20 μ m).Bubble contacts with suspension flco in the waste water can obtain good adhesivity, and has strengthened the interpolymerization of microbubble and flocs unit.Growing up of the generation of microbubble and flco carried out simultaneously, and a large amount of microbubbles are mixed in the inner formation of flco in conjunction with firm gas enclosure flco, and the bubble separation effect is obviously improved;
(2) adopt deflector type electrolytic gas floating chamber and sectional type multi-electrode recurrence interval property cycle power mode, weakened the influence of circulation greatly, improved the hydraulics of coagulation, increased the utilising efficiency of electrolysis bubble, the consumption of electric energy also is able to remarkable reduction, and energy consumption is little, the processing efficiency height.When the electrode pad distance was 2mm, power consumption only was 50% of traditional electrofloatation mode;
(3) adopt overpotential lower and low-cost Stainless Steel Cloth and graphite material make negative electrode and anode, not only power consumption reduces, export license is little, is difficult for passivation, and treatment effect also obviously is better than traditional electrofloatation;
(4) sludge treatment is convenient.The microbubble density that electrolysis produces is big, and bubble diameter is little, and bubble and flco associativity and last buoyancy are good, can realize that the automatic buoyance lift of mud effluxes, and the come-up moisture percentage in sewage sludge are low, need not further to dewater concentration;
(5) simple in structure, take up an area of and lack no movement parts.
(6) the utility model has adopted the sectional type multi-electrode recurrence interval property cycle power mode of Controlled by Programmable Controller, and working current, pulse-repetition and each electrode working hour are conveniently adjusted, are easy to automatic control.Leakage field protection powerstat has the automatic short-circuit protection function, and when short circuit occurring, transformer increases by self leakage field induction reactance and is able to automatic protection, and so electrical system is safe and reliable, operation and control are simply.
