Description

Reverberator for recovery processing waste lead acid accumulator

[technical field]

The utility model relates to the lead-acid accumulator field, relates in particular to solid waste reverberator for recovery processing in the waste and old lead acid accumulator.

[background technology]

The application of lead-acid accumulator is very extensive, can provide power for various product.Substantially 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 easily causes " 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) to carry out under the effect of electrolyte (dilution heat of sulfuric acid), the grid frame of pole plate wherein, traditional storage battery lead-antimony alloy manufacturing, maintenance-free battery 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 enter 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 easily causes 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 enters under the soil and pollutes in this technology 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 easily revealed, and environment is polluted.The flue dust suspension 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 by food chain.Abroad also have and adopt first desulfurization, the melting technique of fire reduction again, but this technical equipment has high input, and 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.

Wherein, it is visual plant in handling that leaded refuse is carried out reverberatory furnace that melting handles, present reverberatory furnace structure is simple, adopt the stokehold that the burning fire door is arranged, the heating of burning of the mode of hand firing operation, it is too big to exist workman's coal to disclose coal ash dirt, and temperature is not in place, time is long, to defective such as human body and environment be unfavorable; Insufficient to solid waste combustion, lead recovery is low; Plumbous liquid pollutes easily from the furnace bottom seepage; When temperature was too high, the furnace expansion distortion was serious; Lead dust is easily gone in the workshop when reinforced, and workman and environment are caused damage.

So, how a kind of reverberatory furnace rational in infrastructure is provided, can not influence operator's health, can not produce and pollute the environment inside and outside the factory, solid waste is fully burnt, improve lead recovery, and can prevent that plumbous liquid is from the furnace bottom seepage, prevent the furnace expansion distortion, become the important topic of waste and old lead acid accumulator recycling those skilled in the art research.

[summary of the invention]

The purpose of this utility model solves the problems of the prior art exactly, propose a kind of reverberator for recovery processing waste lead acid accumulator, can not influence operator's health, can not produce and pollute the environment inside and outside the factory, solid waste is fully burnt, improve lead recovery.

For achieving the above object, the utility model proposes a kind of reverberator for recovery processing waste lead acid accumulator, comprise body of heater, charging aperture, smoking dirt pipe, described body of heater is provided with some charging apertures, the top of body of heater is provided with smoking dirt pipe, also comprise some gas pipes, described gas pipe is arranged on the top of body of heater, communicates with the inside of body of heater by some mouths of pipe.

As preferably, described gas pipe communicates with body of heater inside by 8 mouths of pipe.

As preferably, also comprise heat-exchange tube, described heat-exchange tube is arranged on the top of body of heater, communicates with body of heater inside.

As preferably, also comprise the iron phase structure, the bottom of described body of heater is provided with the iron phase structure.

As preferably, also comprise some reinforcing distortion iron props, the lateral surface of described body of heater is provided with some reinforcing distortion iron props vertically.

As preferably, described reinforcing distortion iron prop adopts 10.

As preferably, described upper of furnace body adopts the thermal insulation fire-resistant brick.

The beneficial effects of the utility model: the utility model adopts gas generator by gas pipe reverberatory furnace to be carried out gas firing and heats, to disclose coal ash dirt too big for workman's coal when having overcome coal combustion, defectives such as temperature is not in place, can not influence the healthy of operator, can not produce and pollute the environment inside and outside the factory; Adopt a plurality of mouths of pipe that sufficient firepower can be provided, the lead-contained solid refuse is fully fused; 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; Heat-exchange tube is installed at the reverberatory furnace top, is connected with heat exchanger in the flue, carry out second-time burning, make firepower bigger, the fusion time is shorter, and the fusion of lead-contained solid refuse is more abundant, and has improved energy utilization rate, and the while has also reduced the flue flow; The bottom of body of heater is provided with the iron phase structure, can effectively prevent plumbous liquid seepage; The body of heater lateral surface is provided with some reinforcing distortion iron props, can prevent that the too high furnace expansion that causes of furnace temperature is out of shape.
