铸造废气处理
发布时间：2018-11-22 发布者：admin
应用领域：
广泛应用于化(hua)(hua)工、电(dian)(dian)子、冶金(jin)、电(dian)(dian)镀(du)(du)、纺织(化(hua)(hua)纤(xian))、食(shi)品(pin)(pin)、机(ji)械制造等(deng)行业过程中(zhong)排放的(de)酸(suan)、碱性(xing)废气的(de)净化(hua)(hua)处理。如调味食(shi)品(pin)(pin)、制酸(suan)、酸(suan)洗、电(dian)(dian)镀(du)(du)、电(dian)(dian)解(jie)、蓄电(dian)(dian)池等(deng)。
It is widely used in the purification of acid and alkaline waste gases discharged from the chemical, electronics, metallurgy, electroplating, textile (chemical fiber), food, machinery manufacturing and other industries. Such as seasoning food, acid, pickling, electroplating, electrolysis, batteries and so on.
一(yi)、铸造废气(qi)的(de)由来(lai)：
铸(zhu)造(zao)废气的产生(sheng)(sheng)主要由于高炉原料(liao)、燃料(liao)及辅助(zhu)原料(liao)的运输、筛(shai)分(fen)、转运过程中(zhong)将产生(sheng)(sheng)粉尘；在高炉出铁时将产生(sheng)(sheng)一些有害废气
二、铸造废气处理原理：
铸造废气(qi)通过引(yin)风机抽出，由引(yin)尘(chen)罩管道进入(ru)除(chu)(chu)尘(chen)器(qi)设备再(zai)进入(ru)光催化(hua)除(chu)(chu)臭设备内(nei)，在高能紫(zi)外线照射下，使挥发性有机物（VOCs）化(hua)学键开环和断(duan)裂(lie)等多种反应（光化(hua)学反应），降解转变成CO2，H2O等低(di)分(fen)子化(hua)合物；
三、覆膜砂铸造过(guo)程：
融化(hua)-造型-下芯(xin)-浇注-后处理(li)等(deng)工序，其中(zhong)在浇注时(shi)产生大量水汽及(ji)树脂，乌(wu)洛托品，硬脂酸钙(gai)，煤粉(fen)，淀粉(fen)，孕育剂（锡）金属合金，在高(gao)温1400℃-1500℃下发(fa)(fa)生化(hua)学反应(ying)分解的氨气，乙酸酯，硫化(hua)氢，无量纲(gang)等(deng)挥(hui)发(fa)(fa)性臭(chou)味。
铸造废(fei)(fei)气(qi)(qi)(qi)通(tong)过引风(feng)机(ji)抽(chou)出，由(you)(you)引尘(chen)罩管道进入除(chu)尘(chen)器设备再进入光催化(hua)(hua)(hua)除(chu)臭(chou)(chou)设备内，在高能(neng)(neng)紫(zi)外线照射(she)(she)下，使挥发性(xing)有(you)机(ji)物（VOCs）化(hua)(hua)(hua)学键(jian)开环和断(duan)裂等多种反应(ying)（光化(hua)(hua)(hua)学反应(ying)），降(jiang)解转变(bian)成(cheng)(cheng)CO2，H2O等低分(fen)子化(hua)(hua)(hua)合物；一方(fang)面利用(yong)高能(neng)(neng)紫(zi)外光照射(she)(she)空气(qi)(qi)(qi)中(zhong)的(de)氧(yang)(yang)(yang)(yang)(yang)气(qi)(qi)(qi)生(sheng)(sheng)(sheng)成(cheng)(cheng)臭(chou)(chou)氧(yang)(yang)(yang)(yang)(yang)，臭(chou)(chou)氧(yang)(yang)(yang)(yang)(yang)吸收紫(zi)外线生(sheng)(sheng)(sheng)成(cheng)(cheng)氧(yang)(yang)(yang)(yang)(yang)自由(you)(you)基(ji)和氧(yang)(yang)(yang)(yang)(yang)气(qi)(qi)(qi)，氧(yang)(yang)(yang)(yang)(yang)自由(you)(you)基(ji)与空气(qi)(qi)(qi)中(zhong)的(de)水(shui)蒸气(qi)(qi)(qi)作用(yong)生(sheng)(sheng)(sheng)成(cheng)(cheng)羟基(ji)自由(you)(you)基(ji)，一种更强的(de)氧(yang)(yang)(yang)(yang)(yang)化(hua)(hua)(hua)剂，与醇、醛、羧酸等有(you)机(ji)废(fei)(fei)气(qi)(qi)(qi)，彻底氧(yang)(yang)(yang)(yang)(yang)化(hua)(hua)(hua)为水(shui)、二(er)氧(yang)(yang)(yang)(yang)(yang)化(hua)(hua)(hua)碳(tan)(tan)等无机(ji)物。另(ling)外，未(wei)吸收紫(zi)外线的(de)臭(chou)(chou)氧(yang)(yang)(yang)(yang)(yang)也(ye)是一种强氧(yang)(yang)(yang)(yang)(yang)化(hua)(hua)(hua)剂，与一些(xie)有(you)机(ji)废(fei)(fei)物接(jie)触后(hou)将(jiang)其氧(yang)(yang)(yang)(yang)(yang)化(hua)(hua)(hua)生(sheng)(sheng)(sheng)成(cheng)(cheng)水(shui)、二(er)氧(yang)(yang)(yang)(yang)(yang)化(hua)(hua)(hua)碳(tan)(tan)等无机(ji)物。
