Abstract

The utility model relates to an improvement of the structure of a hydrogen-canceling hood of the conventional stationary lead storage battery, which adopts an aluminium or glass cooling hood with a hole for air escaping not only to improve the heat dissipation performance but also to avoid explosion of overrun hydrogen gas in the cooling hood. Meanwhile, a water returning disc is arranged above electrolyte level on the basis of different ways of water and gas to simplify the process and enhance the universality of the utility model to batteries of different specifications as well as to improve over-charge resistance of the batteries, and the storage batteries is capable of maintaining liquid level without adding water.

Description

Explosion-proof hydrogen-eliminator with new structure

The utility model is the improvement that belongs to the hydrogen-eliminator structure of lead accumulator.

In the use of stationary lead-acid storage battery, all adopt the technology of hydrogen-eliminator (or being the catalysis bolt) to replace acid-proof flame proof cap technology at present both at home and abroad in succession, so that it is adapted to forbid the underground works of hydrogen and acid mist, the principle of chemical engineering and other special engineered hydrogen-eliminator is exactly that a large amount of acid mists with charge in batteries latter stage stop in battery, and make the hydrogen of separating out, carrier of oxygen enters chance catalyst in the catalytic bed and becomes steam, by overflowing in the corundum reaction bed (or being air filter cover), on cooling dome, be condensed into the globule and flow back in the electrolyte of battery again.Thereby prevented the acid mist effusion, again hydrogen has been eliminated entering the battery chamber simultaneously.Explosion-proof can be played like this and the height of battery liquid level can be kept again for a long time.So far, the external hydrogen-eliminator that adopts is the cooling dome of manufacturing with plastics mostly, because its poor radiation, volume is very big in the time of reaching favorable cooling effect and then manufacture.And be to take steam to go the same way to the backflow of condensed water, promptly sour vapour of Shang Shenging and decline condensed water are walked same pipeline, and poor effect then refluxes.Though domestic had metallic aluminium on probation to do cooling dome in recent years, do not offer steam vent.The excess air that can not disappear is discharged, thereby make cell internal pressure excessive, easily cause the danger of the broken battery of drum.And the reactor of domestic hydrogen-eliminator on probation is an opening at present, and the water of condensation is dropped in the reaction zone from the top, and catalyst is made moist, the active reduction or inefficacy.Simultaneously, the return pipe of condensed water (the different road of steam) is to be inserted in the electrolyte, and this not only is subjected to the different restriction of battery screw thread specification, and manufacturing process is also complicated.

The purpose of this utility model will be found out rational structure and material exactly, and to overcome the shortcoming of the above-mentioned hydrogen-eliminator that adopts at present both at home and abroad, promptly heat dispersion is poor; Steam is gone the same way and back-flow velocity is slow, and overcharge resistance performance is poor; Return pipe is in electrolyte and the water droplet that is subjected to easily to be condensed in the restriction of battery specification and the reactor is wet etc.

At above-mentioned all frauds, the utility model has adopted the cooling dome (3) of aluminum or glass, and have a transpiration hole (2) at its top, both improved thermal diffusivity, excessive gas is in time discharged by transpiration hole (2), thereby avoided density of hydrogen to cross the possibility of limitting and setting off an explosion.In the condensate return part, adopted the water returning disk (11) that is positioned on the liquid level, it makes the condensed water that is flowed down by return pipe (9) form certain liquid level in water returning disk (11).Play the effect of water seal, directly enter the condensation chamber of water vapour to prevent the acid gas in the battery chamber.Adopt this structure, not only make the different road of steam, improved the backflow effect, and the whole simplified manufacturing process that makes.Also add simultaneously the lid of handling through silicone oil of making by corundum (4) in the past on the corundum reactor of opening, this lid directly is buckled on the air filter cover (5), cement with rubber seal then, make condensed water be unlikely and be dropped on the catalyst (6), so just can guarantee its catalytic activity.Do not hinder the effusion of steam yet.

Owing to adopted aforesaid new structure, therefore, compare with the hydrogen-eliminator that uses at present both at home and abroad, not only structure, work simplification, and all can conveniently use for the storage battery of different screw thread specifications, the cover seat (7) that promptly adds a base and this hydrogen-eliminator again joins and just can use.For example, will be with the hydrogen-eliminator of GGM-300AH for GGF-300AH, then only need do one and get final product with the join base of the screw thread (M30) that (internal thread is M48) join with following storage battery sealed interface again of this hydrogen-eliminator cover seat (7).

Claims
