Dry lotus battery plus liquid behind Wen's raise, battery heating-up not very obviously, this is because dry lotus electricity's polar plate's course resist oxidation treatment, leave the factory de battery as is be in adequate electricity condition, plus liquid behind and then be OK load usage; common pole board battery, not resist oxidation treatment, negative plate be in half adequate electricity's conditions, equivalent to a part materials be in for plumbic oxide and rare sulphuric acid react bring forth plenty of quantity of heat, therefore warm long very high.

干荷电池加液后温升高，电池升温不十分明显，这是因为干荷电极板经过抗氧化处理，出厂的电池以是处于充足电状态，加液后即可负荷使用；普通极板的电池，未经抗氧化处理，负极板处于半充足电状态，相当一部分物质处于为氧化铅和稀硫酸反应产生大量的热量，因而温长很高。

Ammonia distilling is to distill the residual ammonia from the blast section in an ammonia still, which evaporate the wolatile ammonia into the saturator to increase the production of vitiol ammonia and send waste water to biochemistry section to decontaminate.

蒸氨生产主要是将来自鼓风冷凝岗位的剩余氨水在蒸氨塔内进行蒸馏处理，使剩余氨水中的挥发氨蒸出后送回到煤气中以增加煤气含氨量进而提高硫酸氨的产量，并将蒸氨废水送至生化污水处理工序进行处理。
