電解車間磁場(chǎng)要求-中英對(duì)照

應(yīng)該考慮到在電解車間中產(chǎn)生的強(qiáng)磁場(chǎng)給工人所帶來的危險(xiǎn)。其中最為嚴(yán)重的問題之一就是對(duì)于工人的心臟起搏器的正常工作所帶來的有害影響。

另一個(gè)需要考慮的問題是在吊裝金屬物體時(shí)強(qiáng)磁場(chǎng)的效應(yīng)，金屬物可能會(huì)被迫和強(qiáng)磁場(chǎng)進(jìn)行校準(zhǔn)。
 
5. 熱量

電解槽在工作時(shí)產(chǎn)生熱量。這種熱量可以使電解車間內(nèi)的工作條件非常不舒服，尤其是在周圍環(huán)境溫度很高的地方。在設(shè)計(jì)電解車間內(nèi)的操作時(shí)需要充分考慮到熱效應(yīng)。

6. 腐蝕性介質(zhì)

電解槽和電解車間內(nèi)相關(guān)的設(shè)備處理著大量的腐蝕性介質(zhì)（鹽水、燒堿蘇打溶液和鹽酸）。工廠的設(shè)計(jì)應(yīng)當(dāng)盡量減少這些液體接觸到的工人的潛在可能性。緊急清洗設(shè)備是必需的。

7. 減壓

電解槽在電流使用時(shí)會(huì)產(chǎn)生氫氣和氯氣。需要充分的過壓保護(hù)系統(tǒng)來確保電解槽的設(shè)計(jì)承受壓力永遠(yuǎn)不會(huì)被超過（參閱第4.7節(jié)）。

電解槽被設(shè)計(jì)成一個(gè)0.2bar g的真空評(píng)級(jí)，這是不足以承受可能由于其被阻塞以及氣體可行的冷卻和壓縮或者電解槽被阻塞和排水而產(chǎn)生的負(fù)壓。程序/設(shè)備應(yīng)該到位以確保電解槽不被這種負(fù)壓事件所損壞。應(yīng)當(dāng)考慮負(fù)壓情況的救急措施以保護(hù)電解槽內(nèi)部的下游設(shè)備不被這種真空所產(chǎn)生的損壞源所損壞。

8. 電解槽組件中的固體垃圾

應(yīng)該充分考慮到被污染的電解槽組件和新的電解槽及其組件的組裝過程中產(chǎn)生的廢料的處理方法。

4. Magnetic Fields

Consideration should be given to the hazards to personnel that can result from the strong magnetic fields generated in a cellroom. One of the more serious issues is the harmful effect on the operation of heart pacemakers in personnel.

Another issue to consider, is the effect of the strong magnetic fields on lifting of metal objects, which may be forced into alignment with the magnetic field.
 
5. Heat

The Electrolysers, when operating, evolve heat. This heat can make working conditions in the cellroom very uncomfortable, especially in locations with a high ambient temperature. Adequate consideration needs to be given to the effect of heat on the design of operations within the cellroom.

6. Corrosive Fluids

The Electrolyser and associated cellroom equipment handle a number of corrosive fluids (brine, caustic soda solution, and hydrochloric acid). The plant should be designed to minimise the potential for these fluids to come into contact with personnel. Emergency wash facilities are required.

7. Pressure Relief

The Electrolysers generate hydrogen and chlorine gases when current is applied. Adequate overpressure protection systems are required to ensure the design pressure of Electrolysers is never exceeded (see section 4.7). 

The Electrolysers are designed with a vacuum rating of 0.2 bar g, which is not sufficient to withstand the underpressure that can be generated should they be blocked in and the gases allowed to cool and condense, or if the Electrolysers are blocked in and drained. Procedures / equipment should be put in place to ensure that the Electrolysers are not damaged by such underpressure events. Consideration should be given to the provision of underpressure relief to protect downstream equipment from these sources of vacuum generated within the Electrolysers.

8. Solid Waste from Electrolyser Components

Adequate consideration should be given to disposal methods for contaminated Electrolyser components and for scrap material from assembly of new Electrolysers and components.
