Abstract
The invention discloses a tubular electrolytic cell for domestic sewage treatment. The tubular electrolytic cell is characterized in that the electrolytic cell is formed by sleeving a cathode external tube and an anode inner tube, wherein the cathode external tube is a titanium tube of which one end is sealed, a nozzle flange and a water inlet adapter tube are arranged at the other end of the titanium tube, and the water inlet adapter tube is perpendicular to the cathode external tube; the anode inner tube is a tube section of which one end is provided with a water outlet adapter tube; a ruthenium coating is arranged on an outer surface of the tube section; the water outlet adapter tube and the anode inner tube are in a manner of concentric circles; the anode inner tube is fixedly sleeved in the cathode external tube through a tetrafluoroethylene supporting piece; and the water outlet adapter tube is sleeved with a tetrafluoroethylene washer and is fixedly connected with a nozzle flange bolt through a flange cover. Compared with the prior art, the tubular electrolytic cell has the advantages that the operations of degradation of organic matters and sterilization and disinfection are performed in the same equipment, the reaction retention time is short, the tubular electrolytic cell is high in treatment efficiency, long in service life of electrodes, simple and convenient to operate, stable in operation and low in cost and is particularly suitable for narrow and small spaces of ship and marine structures.
Description
Technical field
The present invention relates to technical field of sewage, specifically a kind of tube type electrolytic tank for boats and ships or sewage processing.
Background technology
At present, after generally all adopting biochemical treatment to reach emission standard, the sanitary sewage that boats and ships produce in navigation enters sea both at home and abroad, biochemical processing process utilizes microbiological deterioration organism, need continuous constant water inlet, so the equipment volume of sewage disposal is large, but boats and ships ride the sea, equipment load is more little more favourable, on ship, operator are limited simultaneously, and the possibility that operates the normal operation of simpler equipment is larger, and treatment effect is also just more obvious.The problem that prior art exists is: equipment load weight, take space in boats and ships and ocean structure body large, and the treatment time is longer, and fluctuation of service easily impacts ocean environment, and processing power is low, and working cost is high.
Also have now the electrochemical treatment of employing sanitary sewage, the chlorine producing with electrolysis and sodium hydroxide generate clorox, and clorox, by the organic matter degradation in sanitary sewage and sterilization and disinfection, makes sanitary sewage qualified discharge.Electrolyzer generally all adopts plank frame, this water of constitution Flow Velocity is slower, the easy fouling of electrode surface, electrolytic oxidation reaction process mixing is simultaneously inhomogeneous, often need to increase to stir (pneumatic blending or mechanical stirring), otherwise reaction time is longer, reaction needed space is large (generally needing the more than 30 minutes residence time), exist reaction efficiency low, the easy fouling of electrode is tight, has a strong impact on electrode life.
Summary of the invention
The tube type electrolytic tank of the one way of life sewage disposal providing for the deficiencies in the prior art is provided, adopt the electrolyzer of tubular structure, after fully being mixed with sanitary sewage, seawater enters tube type electrolytic tank, the chlorine that electrolysis produces and sodium hydroxide generate clorox, clorox is by the organic matter degradation in sanitary sewage and sterilization and disinfection, make sanitary sewage qualified discharge, reaction time is short, processing efficiency is high, electrode life is long, compact construction, electrolytic efficiency is high, greatly reduce the requisite space of degradation of organic substances and sterilization and disinfection, easy and simple to handle, stable, expense is low, and it is little to take space in boats and ships and ocean structure body, reliably, effectively protected ocean environment.
The technical scheme that realizes the object of the invention is: the tube type electrolytic tank of one way of life sewage disposal, be characterized in that this electrolyzer is formed by negative electrode outer tube and anode inner tube suit, the titanium pipe that described negative electrode outer tube is an end closure, it is vertical setting with water inlet adapter and water inlet adapter with negative electrode outer tube that its other end is provided with nozzle flange; Described anode inner tube is that one end is provided with the pipeline section that water outlet is taken over, and its pipeline section outside surface is provided with ruthenium coating, and water outlet adapter and anode inner tube are concentric(al) circles setting; Described anode inner tube is fixedly set in negative electrode outer tube by tetrafluoroethylene strut member, and its water outlet is fixedly connected with nozzle flange bolt by blind flange after taking over suit tetrafluoroethylene packing ring.
On the port shrouding of described water outlet adapter and negative electrode outer tube, be respectively equipped with anode connection plate and cathode connection plate.
Described tetrafluoroethylene strut member is for establishing the standoff collar.
The present invention compared with prior art has degradation of organic substances and sterilization and disinfection carries out in same equipment simultaneously; reaction time is short; processing efficiency is high, and electrode life is long, compact construction; electrolytic efficiency is high; greatly reduce the requisite space of degradation of organic substances and sterilization and disinfection, easy and simple to handle, stable, expense is low; and it is little to take space in boats and ships and ocean structure body, reliably, has effectively protected ocean environment.

Embodiment
The adapter 11 of intaking is connected with combined sewage pipeline, and water outlet is taken over 8 and is connected with water shoot, and electrolysis power accesses respectively cathode connection plate 4 and anode connection plate 9.The sanitary sewage that mixes seawater enters electrolyte chamber 12 by the adapter 11 of intaking, connect cathode connection plate 4 and anode connection plate 9 power supplys simultaneously, mix the sanitary sewage of seawater at the narrow and small and impartial negative electrode of spacing, product fast produces electrolysis between anode, a large amount of bubbles that the chlorine that moment produces and hydrogen form, it is vertical with the water (flow) direction in duct chamber that it separates out direction, and flow velocity and the electrolyte chamber 12 interior formation turbulent flow of the bubble constantly producing in tubular type faster, in water, reducing substance fully mixes and contacts with oxidizing substance, oxygenizement starts in this process, electrolysis and oxygenizement are carried out in the same space simultaneously, reduced mixing process, saved oxidizing reaction requisite space.Current enter anode inner chamber 14 reaction zones after by electrolyte chamber 12, and oxidizing reaction is proceeded, and whole reaction time is about 5 minutes, far below 30 minutes electrolytic reaction residence time of the electrochemistry sewage disposal device of prior art.Flow velocity and the electrolyte chamber 12 interior formation turbulent flow of the bubble constantly producing in tubular type faster, make in water reducing substance react probability with oxidizing substance when increasing, current constantly wash away polar board surface (in chamber, flow velocity reaches 30～50cm/s), in water, calcium, magnesium ion are difficult to adhere to, make polar board surface less scaling, extended the work-ing life of electrode, device electrolytic efficiency is high, have easy to operate, the advantage of a little repair.
More than just the present invention is further illustrated, and not in order to limit this patent, all is the present invention's equivalence enforcement, within all should being contained in the claim scope of this patent.
