Description

Solid waste recovery and processing system in the waste and old lead acid accumulator
[technical field]
The present invention relates to the lead acid accumulator field, relate in particular to solid waste recovery and processing system in the waste and old lead acid accumulator.
[background technology]
The application of lead acid accumulator is very extensive, can power be provided for various product.Basically all be to adopt lead acid accumulator that walking power is provided on the electric bicycle that the smokeless vehicles of conduct are at present widelyd popularize.But lead acid accumulator is prone to cause " secondary pollution " that the development of this novel walking-replacing tool is quite blamed.
Lead acid accumulator is formed by positive/negative plate, dividing plate, housing, electrolyte and wiring pile are first-class; The chemical reaction of its discharge is to rely on positive plate active material (brown lead oxide and lead) and positive and negative pole active matter (spongy pure lead) under the effect of electrolyte (dilution heat of sulfuric acid), to carry out; The grid frame of pole plate wherein; Traditional storage battery is used the lead-antimony alloy manufacturing, and maintenance free cell is to make with lead-calcium alloy.
Waste and old lead acid accumulator contains heavy metal and electrolyte solutions such as acid, alkali such as mercury, lead, cadmium, chromium, nickel, manganese, in case get into human body, can damage nervous system, hematopoiesis function, kidney and bone, and what have can also be carcinogenic.Heavy metal that waste and old lead acid accumulator decomposited that arbitrarily throws and poisonous waste liquid can cause serious threat to the ecological balance and health, become new environomental pollution source.
The recovery processing technique imperfection of lead acid accumulator is prone to cause secondary pollution, has become its key in application problem of restriction.At present, the reviver factory that reclaims lead acid accumulator adopts the easy simple mixing method of reverberatory furnace to smelt.The acid solution easy to leak gets under the soil and pollutes in this technology storage battery unloading process; Leaded thing burning is insufficient, and lead recovery is low, generally can only reach about 80%, and residual lead is discharged in the atmosphere and still can pollutes; More lead dust is arranged in the workshop, influence operator's physical and mental health; Waste gas and soot emissions device simple are prone to reveal, and environment is polluted.The flue dust suspended matter and the heavy metal ion that contain natural subsidence in air in the waste water of these leakages directly cause the pollution to underground water and resident's drinking water; Contain mineral deposits such as lead, arsenic, antimony in the waste residue in soil, be difficult to be eliminated, and progressively in crops, assemble,, cause harm animal and human's body through food chain.Wherein, the main reason that causes above-mentioned pollution is exactly fairly simple to lead-contained solid treatment of wastes produced equipment, and leaded thing burning is insufficient, and the dedusting before the toxic emission is not thorough.Abroad also have and adopt first desulfurization, the melting technique of fire reduction again, but this technical equipment is thrown National People's Congress, needs plurality of devices such as blast furnace, reverberatory furnace, electric furnace and converter, and equally also can pollute environment in its course of work.
So, how a kind of leaded thing sufficient combustion is provided, waste gas dedusting solid waste recovery and processing system has completely become the important topic that waste and old lead acid accumulator recycling those skilled in the art study.
[summary of the invention]
The object of the invention solves the problems of the prior art exactly, proposes solid waste recovery and processing system in a kind of waste and old lead acid accumulator, can make leaded thing burning more abundant, and waste gas dedusting is more thorough.
For realizing above-mentioned purpose, the present invention proposes solid waste recovery and processing system in the waste and old lead acid accumulator, comprise reverberatory furnace, refining furnace, flue, dedusting room; Said refining furnace is connected the reverberatory furnace rear end, and the outlet flue of reverberatory furnace and refining furnace communicates with the front end of flue, and the dedusting room communicates with the rear end of flue; Also comprise gas generator; Said gas generator is connected with refining furnace with reverberatory furnace, and the said mouth of pipe is arranged on the front end of reverberatory furnace, reverberatory furnace rear end and flue junction be provided with can air draught port; Also comprise heat exchanger, said heat exchanger is installed in the front end of flue near the reverberatory furnace place.
As preferably, said gas generator is connected with reverberatory furnace through the mouth of pipe more than 2.
As preferably, said gas generator is connected with reverberatory furnace through 8 mouths of pipe.
As preferably, also comprise water film dust removal device, said water film dust removal device is connected the rear end in dedusting room.
As preferably, said water film dust removal device comprises circulating water pool, some shower nozzles and water pump, and said water pump communicates with circulating water pool inside, and shower nozzle is connected with the delivery port of circulating water pool.
Beneficial effect of the present invention: the present invention all adopts gas generator to carry out gas firing to the heating of reverberatory furnace and refining furnace, adopts a plurality of coal gas mouths of pipe that sufficient firepower can be provided, and makes leaded thing fusion fully; The coal gas mouth of pipe is arranged on the front end of reverberatory furnace, and the rear end of reverberatory furnace is provided with the port with air draught function, and the fire of front is constantly walked about backward, and the leaded thing of back also can fuse fully simultaneously, has saved the energy; Front end at flue is installed heat exchanger near the reverberatory furnace place, carries out second-time burning, makes firepower bigger, and the fusion time is shorter, and leaded thing fusion is more abundant, and has improved energy utilization rate, has also reduced the flue flow simultaneously; Behind dedusting room bag-type dust, adopt water film dedusting again, dedusting is more thorough, and the gas of discharge is pollution-free to atmosphere.The present invention is more abundant to the burning of lead-contained solid refuse, and waste gas dedusting is more thorough, and energy utilization rate is high, and processing procedure is perfect, can not cause secondary pollution to environment, has great economic benefit and social benefit.
Characteristic of the present invention and advantage will combine accompanying drawing to be elaborated through embodiment.
