Abstract
The utility model relates to a micro electrolytic bed for removing heavy metals, which is used for the treatment of waste water in the chemical industry. The utility model comprises an electrolytic bed casing body, a liquid inlet at the bottom of the casing body, a liquid outlet on the top of the casing body, and a packed bed in the casing body. The electrolytic bed is a post type tower body, and two heads realize the sealed filling via an upper sealed head and a lower sealed head. The position between the sealed head and the tower body is connected via a hole plate, and the inside of the lower sealed head is provided with a water cap plate. Activated carbon is filled among the upper water distribution cap, the water cap, and the lower hole plate. The packed bed forming a cathode and an anode of a primary battery is arranged between the lower hole plate and the upper hole plate. The upper sealed head is additionally provided with a pressure gauge and an air outlet. The utility model relates to a closed type reaction. A liquid inlet and a liquid outlet can be opened to realize the quick flow of the fluid. The utility model changes the defect that after the upper opening of a self-overflow type reaction tower is completely opened, the flow capacity can not be increased.
Description
The utility model relates to a kind of micro-electrolysis device that removes heavy metal that is used for chemical wastewater treatment.
At present, the little bed electrolysis that generally adopts all is the uncovered bed electrolysis that declines basically both at home and abroad, and this bed electrolysis advances waste water by the bottom, and adverse current is overflowed from suitable for reading behind waste water process iron filings or other filler.The disadvantage of the little bed electrolysis of this structure is that flow rate of liquid can not be fast, when handling organic wastewater, because the residence time that little electrolytic decomposition organism needs is longer, so this little bed electrolysis that can only slug flow speed is more suitable, and when processing contains the waste water of heavy metal, because it is very fast that redox reaction removes heavy metal speed, the reaction of galvanic cell is again a thermopositive reaction, high temperature is unfavorable for the carrying out that react, therefore, liquid was restricted in the residence time of bed electrolysis, and the requirement of general treatment capacity is bigger, and liquid has only fast by little bed electrolysis, reaction is efficiently carried out, and the as easy as rolling off a log filler that allows of flowing fluid is taken out of from suitable for reading fast, enters next process by overflow weir, and therefore the uncovered bed electrolysis that declines is not suitable for being used for flow velocity micro-electrolysis reaction faster.
The utility model is just in order to overcome above-mentioned deficiency, provide a kind of simple in structure, be suitable for the effective withstand voltage bed electrolysis that declines that liquid passes through fast.
Improvements of the present utility model are traditional opened type of little bed electrolysis is changed into closed, constitute the withstand voltage bed electrolysis that declines, and realize that liquid is fast by little bed electrolysis.Specifically, a kind of withstand voltage bed electrolysis that declines, comprise the fluid inlet of bed electrolysis housing, housing bottom, the liquid outlet of case top, the bed of packings of enclosure interior, it is characterized in that bed electrolysis is a column tower body, the close envelope of filling out is realized by upper and lower end socket in two, be connected with orifice plate between end socket and tower body, be provided with water cap plate in the lower cover, last water distribution cap, filling gac between water cap and orifice plate, distributing between upper and lower orifice plate constitutes the dipolar bed of packings of galvanic cell yin, yang, is provided with tensimeter and venting port on the upper cover in addition.Heavy metal-containing waste water enters tower body from fluid inlet, falls into muddy thing in the material by activated carbon filtration, forms numerous microbattery in bed of packings, reacts, and removes heavy metal, and the liquid after the removal of impurities is discharged from liquid outlet.The utility model is a kind of enclosed bed electrolysis, duration of service is long, the gas that produces owing to the galvanic cell reaction in the tower body is cumulative, the tower body internal pressure is excessive, influence flow velocity, when checking that by tensimeter the intravital pressure of tower acquires a certain degree, in time open venting port and discharge gas, need not to influence technical process.
Because the flow rate of liquid that the utility model is suitable for is very fast, goes out reactor for fear of filler, also is provided with screen cloth on the upper and lower orifice plate.
Also be provided with batching hole, manhole and visor on the tower body of the present utility model, so both guaranteed in case of emergency that filler can be discharged from manhole, and can wait where necessary again from batching hole and add the reaction filler, anti-ly needn't raise upper cover, visor can also be watched filler and consume situation.
In whole technology operational process, the utility model is closed reaction, it only need open fluid inlet and liquid outlet, can realize flowing through fast of liquid like this, change the flow that brings after self-overflow type reaction tower whole the opening wide suitable for reading and can't become big deficiency, the utility model is simple in structure, and the utmost point is suitable for removing the micro-electrolysis reaction of heavy metal.
Accompanying drawing is a structural representation of the present utility model.
Further specify the utility model below in conjunction with embodiment.
Agent structure tower body 6 and last lower cover 2,8 by orifice plate 4,7 are connected to form sealed structure, on, orifice plate 4,7 tops all are equipped with screen cloth, to guarantee that the intravital filler of tower is not washed away by liquid, micro-electrolysis reaction adopts the adverse current feed liquor, thereby lower cover 8 is provided with the fluid inlet 10 of liquid bottom, be provided with water cap plate 9 in the lower cover in addition, last water distribution cap, fill out with active carbon filler 15 between water cap plate and the orifice plate 7, with the turbid material in the elimination feed liquor, design has batching hole 12 on the tower body 6, manhole 11, visor 13, the realization filler needn't be taken end socket apart in the intravital turnover of tower, for guaranteeing that liquid passes through smoothly in that tower is intravital, 5 2/3rds volumes of filling out tower body of the intravital bed of packings of tower, vacant upper cover 2 can also be collected the gas that produces in the reaction, indication by upper cover upward pressure table 14, in time open vent valve 1, bleed off this part gas, thereby guarantee that liquid flows out from liquid outlet 3 densely.
