Description
Invention field
The present invention relates to the gas extraction system of storage battery.More particularly, the present invention relates to a kind of gas extraction system that can be used for the lead acid accumulator of motor vehicles.
Background of invention
Lead acid accumulator is a known systems.Lead acid accumulator can be used for various application, comprises the vehicles of the light vehicle of automobile, truck, ship, aircraft and golf cart and so on.
Lead acid accumulator generally comprises the battery cell case of an encapsulation storage battery activeleg.Activeleg remains in the isolation ward that is commonly referred to " electrolysis tank (cell) ".Typical lead acid accumulator has at least six electrolysis tanks, and each electrolysis tank produces 2 volts electromotive force.Electrolysis tank is rectangle normally, and each electrolysis tank comprises a plurality of positive plate and negative plates of alternately arranging of isolating with distance piece.Positive plate generally comprises the active material of lead oxide as them, and negative plate generally comprises the metallic lead of high porosity structure as active material.Separator is made by porous electrically non-conductive material sheet, so that make each positive pole and negative plate be adjacent electrode plate insulation.
Be called electrolytical aqueous solution activation lead acid accumulator by in electrolysis tank, adding.Electrolyte is a kind of the have sulfuric acid of predetermined proportion and concentrated solution of water.Electrolytical proportion is according to the stoichiometry design, to satisfy the electrochemistry needs of storage battery.
The electrolyte that injects electrolysis tank causes the generation of chemical reaction.Positive plate and electrolyte chemical reaction produce water and lead sulfate.Negative plate and electrolyte chemical reaction produce lead sulfate.Reaction in positive pole and the negative plate proceeds to electrolyte becomes rare aqueous solution.In the time can not again chemical reaction taking place, storage battery has been called " discharge ".
Lead acid accumulator is characterised in that it is that chemistry is reversible.By applying electric current for positive plate and negative plate the battery discharging process is reversed with the opposite direction of course of discharge.When electric current passed through pole plate, lead sulfate resolved into lead and SO
4, water resolves into hydrogen and oxygen.SO
4Combine generation sulfuric acid with hydrogen.Oxygen generates lead oxide with plumbous the combination.This process is called " charging " in the art.
The charging of lead acid accumulator produces a large amount of gas, mainly is hydrogen and oxygen.Continue with charging process, the pressure in battery cell case and/or the electrolysis tank increases.The generation of gas and pressure improve in the electrolysis tank, if get rid of inadequately, may cause the badly damaged of battery cell case.The danger that gas also causes external spark to set off an explosion.As a result, the storage battery process industry needs always and continues that needs are a kind of can be discharged into system the atmosphere to gas from battery cell case and/or electrolysis tank.
The electrolyte that gas in the electrolysis tank may be carried evaporation secretly also is known in the art.As a result, the discharge of gas has produced an extra problem.When the electrolytical gas of evaporation is carried in discharge secretly, reduced the electrolytical amount that can be used for carrying out chemical reaction originally with positive plate and negative plate.Electrolytical loss will reduce the maximum probable life of storage battery.Therefore, except needs are discharged gas in the electrolysis tank, also need to keep and impel electrolyte to turn back in the electrolysis tank.
In order to satisfy above-mentioned needs, the manufacturer of this area has utilized various gas extraction system, and wherein gas is discharged by baffling passage in the battery cap and steam vent.The gas extraction system design that has two types known in the state of the art: vertical-type gas extraction system and horizontal type gas extraction system.Typical vertical-type gas extraction system comprises venting plug, adds material trap and deflection plate.Venting plug generally comprises one and has a dark cylindrical chamber that is coupled to the base plate in the filler trap.When gas was vertically discharged from electrolysis tank, heavier electrolyte was fallen on the base plate of chamber.The chamber base plate is formed the gradient to a central drain and exhaust dual-purpose hole inclination, vertically rises by its gas, and the electrolyte that collects on the chamber base plate is back in the electrolysis tank.After by the deflection plate that prevents electrolyte arrival gas outlet, the gas that compiles is discharged in the environment by the gas outlet.United States Patent (USP) 4,186,247,4,338,383,4,562,126 and 4,636,446th, the representative of vertical-type gas extraction system.
As a comparison, the horizontal type gas extraction system generally comprises the dust trapping chamber of a plurality of length, discharge opeing and the dual-purpose opening of exhaust (similar with the opening of vertical-type gas extraction system), a plurality of deflection plates and at least one gas outlet.A plurality of long dust trapping chamber horizontal-extending, at least a portion of crossing over storage battery.The dual-purpose opening of discharge opeing and exhaust laterally passes through the gas outlet.Therefore, enter the length that the electrolyte of dust trapping chamber and gas must cross-current be crossed dust trapping chamber, arrive the gas outlet.The flowing of deflection plate control gaseous, and the base plate of dust trapping chamber normally tilts, and flow back in the electrolysis tank by discharge opeing and the dual-purpose opening of exhaust to impel electrolyte.The horizontal type gas extraction system also can comprise one allow gas between a plurality of long dust trapping chamber and among circulation or the collecting system that mixes.The use of collecting system is the quantity of discharging the required gas outlet of gas in order to reduce, thereby reduces cost.United States Patent (USP) 4,371,591,4,486,516,4,891,270 and 5,424,146th, the representative of horizontal type gas extraction system.
The horizontal type gas extraction system is considered to the improvement of vertical-type gas extraction system.By design, the horizontal type gas extraction system is intended to make the area maximum that can discharge gas.But it exists deficiency.The horizontal type Design of Exhaust System generally includes many complexity and staggered parts.The complexity of parts will force gas laterally to pass through the winding raod footpath before discharging by exhaust outlet.But such horizontal type gas extraction system also is difficult to assembling and manufacturing cost height usually.For example, United States Patent (USP) 4,486,516 show a kind of horizontal type gas extraction system with electrolyte tap, exhaust outlet, cup and hopper.This gas extraction system also comprises an escapement that cup and hopper are kept apart.Cup has an inclined floor that slopes downwardly into hopper.Hopper is further limited by a base plate that tilts to outage that is positioned under the inclined floor.Escapement comprises a plurality of alternation sums that define the zigzag path that gas must process before entering exhaust outlet wall that is mutually related.Because used many so interrelated and staggered parts, the manufacturing cost of horizontal type gas extraction system is high shown in this patent.
In order to raise the efficiency, the gas extraction system of lead acid accumulator should maximally utilise the space above the battery cell case, so that gas is discharged in electrolysis tank.Gas extraction system also should have can impel electrolyte effectively and promptly to turn back to supplementary features in the electrolysis tank.In addition, wish to design always and a kind ofly be easy to make and cheap gas extraction system.Therefore, not only can impel gas to discharge from electrolysis tank, and electrolyte is flow back in the electrolysis tank as much as possible fast, be a kind of challenge and needs in this area always.
Therefore, an object of the present invention is to provide a kind of making to can be used for the maximized gas extraction system in space that gas is discharged from electrolysis tank.Another object of the present invention is the gas extraction system that will provide a kind of evaporation electrolyte that prevents to be entrained in the gas to overflow.A further object of the present invention is will provide a kind of to be easy to assembling and to make, and discharges gas effectively, and makes electrolyte turn back to gas extraction system in the storage battery electrolysis tank.From the following description, can understand other purpose of the present invention.
