Technical Field

The invention belongs to the technical field of battery detection, and particularly relates to an exhaust alkaline washing metering device suitable for a valve control type sealed lead-acid storage battery column type safety valve.

Background

The lead-acid storage battery can generate gas due to the reaction of electrolytic water in the later charging period, although the accumulation of electrolytic gas can be reduced by the cathode absorption action, the gas in the storage battery can be slowly accumulated along with the proceeding of float charging and the existence of overcharge in the later period, and if the gas pressure in the storage battery exceeds the valve opening pressure of the safety valve, the gas accumulated in the storage battery can be discharged through the safety valve, so that the internal pressure of the storage battery is reduced. Acid liquor in the storage battery is brought out in the form of acid mist in the gas discharging process. The escape of acid mist can cause the loss of acid liquor of the storage battery, and the output capacity and the service life of the storage battery are influenced; meanwhile, the acid mist can also corrode other equipment and even damage human health when escaping to the outside. On the other hand, the air discharge amount from the safety valve is an important index for measuring the electrolyte loss, if the air discharge amount is large and the air discharge frequency represents that the operation condition of the storage battery needs to be adjusted urgently, the frequent air discharge can also aggravate the water evaporation of the electrolyte, and the failure risk of the battery is further increased.

The invention aims to overcome the defects of the prior art and provide a load control method for a parallel operation waste incineration treatment boiler, which can accurately measure the air displacement of a column type safety valve of a valve control type sealed lead-acid storage battery, indicate the condition of acid mist existing in the exhaust gas of the storage battery and carry out alkali washing.

The invention adopts the following specific technical scheme:

The utility model provides an exhaust alkali washing metering device suitable for valve accuse formula sealed lead acid battery column type relief valve, includes lead acid battery, is provided with the relief valve on lead acid battery, its characterized in that: one end of an air taking pipe is sleeved on the safety valve, and the other end of the air taking pipe is connected with an air inlet of the wet gas flowmeter.

Furthermore, the gas outlet of the wet gas flowmeter is hermetically communicated with the alkaline washing container.

Detailed Description

The present invention is further described in the following examples, but the technical content described in the examples is illustrative and not restrictive, and the scope of the present invention should not be limited thereby.

An exhaust alkaline washing metering device suitable for a valve-regulated sealed lead-acid battery column type safety valve is disclosed, as shown in figure 1, and comprises a lead-acid battery 12, wherein a safety valve 4 is arranged on the lead-acid battery, and the innovation of the invention is as follows: one end 3 of a corrosion-resistant gas taking pipe 1 is sleeved on the safety valve, and the other end of the gas taking pipe is connected with a gas inlet 5 of a wet gas flowmeter 6.

In this embodiment, the gas outlet 11 of the wet gas flowmeter is in sealed communication with the alkaline cleaning vessel 9 through another corrosion-resistant gas intake pipe 7 (through a sealing structure such as a sealing rubber ring 8 or a sealing rubber cover provided on the alkaline cleaning vessel). The two gas taking pipes are both made of an ethylene-diene copolymer, and the inner diameter is phi 6. The outer edge of one end of the gas taking pipe communicated with the safety valve is sleeved with a binding band 2 or a hoop, and one end of the gas taking pipe is tightly connected with the safety valve.

The wet gas flowmeter is of LMF corrosion-resistant type, the flow per revolution is 0.0002L, the rated flow is 0.02L/h, and the minimum scale is 0.1 multiplied by 10^-51 drop of methyl red indicator (0.1% 60% ethanol or its sodium salt aqueous solution) was added to the distilled water in the flow meter. A0.1 mol/L sodium hydroxide aqueous solution is placed in the alkaline washing container, and the alkaline washing container is provided with an exhaust port 10.

The using process of the invention is as follows:

1. one end of the gas taking pipe is tightly bound outside a column type safety valve of the valve control type sealed lead-acid storage battery by a binding belt, so that the exhaust gas at the joint can not escape.

2. The other end of the gas taking pipe is connected with the gas inlet of a miniature wet gas flowmeter, the flowmeter is horizontally placed on the shell of the storage battery, and the gas valve is opened.

3. A0.1 mol/L NaOH solution was placed in the caustic wash bottle and connected to the exhaust of the flow meter using a gas line.

According to the invention, the air displacement of the column safety valve of the valve-controlled sealed lead-acid storage battery can be accurately measured, so that the prejudgment on a certain battery in the whole running storage battery pack, which has failure risk due to lack of electrolyte, can be carried out. The device can indicate the condition that acid mist exists in the gas exhausted by the storage battery, and carry out alkaline cleaning, thereby avoiding influencing the output capacity and the service life of the storage battery, and simultaneously avoiding the acid mist from escaping to the outside and also corroding other equipment, even causing damage to human health. The negative pole self-discharge condition caused by water loss in the storage battery or oxygen entering the battery due to frequent opening caused by aging failure of the safety valve is avoided.
