大型焊(han)烟(yan)滤(lv)(lv)(lv)(lv)筒除(chu)尘(chen)(chen)(chen)器具(ju)有结构(gou)(gou)紧凑(cou)、占(zhan)地面(mian)(mian)(mian)积(ji)小、维修(xiu)(xiu)方(fang)便(bian)(bian)等显著优(you)点。除(chu)尘(chen)(chen)(chen)效率达99.5%以(yi)上,废(fei)气(qi)排(pai)放(fang)≤30mg/m3,优(you)于GB16297—1996(120mg/m3)的(de)(de)排(pai)放(fang)标(biao)准(zhun)具(ju)有以(yi)下优(you)点:的(de)(de)空间利(li)用(yong)率过滤(lv)(lv)(lv)(lv)元(yuan)件滤(lv)(lv)(lv)(lv)筒采折叠的(de)(de)形式(shi)(shi)(shi)布置(zhi)滤(lv)(lv)(lv)(lv)料,过滤(lv)(lv)(lv)(lv)面(mian)(mian)(mian)积(ji)与其所占(zhan)体(ti)积(ji)之(zhi)比(bi)(bi)是传(chuan)统(tong)滤(lv)(lv)(lv)(lv)袋的(de)(de)30-40倍,达到300m2/m3。使(shi)(shi)用(yong)滤(lv)(lv)(lv)(lv)筒可(ke)以(yi)使(shi)(shi)除(chu)尘(chen)(chen)(chen)器结构(gou)(gou)加紧凑(cou),减少(shao)(shao)除(chu)尘(chen)(chen)(chen)器的(de)(de)占(zhan)地面(mian)(mian)(mian)积(ji)和空间。 节能(neng)性(xing)好,滤(lv)(lv)(lv)(lv)料使(shi)(shi)用(yong)寿命长,滤(lv)(lv)(lv)(lv)筒式(shi)(shi)(shi)除(chu)尘(chen)(chen)(chen)器因其滤(lv)(lv)(lv)(lv)料布置(zhi)密(mi)度大,较小体(ti)积(ji)里(li)可(ke)以(yi)有很大的(de)(de)过滤(lv)(lv)(lv)(lv)面(mian)(mian)(mian)积(ji),因而可(ke)以(yi)降低(di)(di)过滤(lv)(lv)(lv)(lv)速度,减少(shao)(shao)系统(tong)阻(zu)力(li),降低(di)(di)运行费用(yong),节约能(neng)源。低(di)(di)过滤(lv)(lv)(lv)(lv)速度也减少(shao)(shao)了气(qi)流对(dui)滤(lv)(lv)(lv)(lv)料的(de)(de)破坏(huai)性(xing)冲刷(shua),延长了滤(lv)(lv)(lv)(lv)筒寿命。 使(shi)(shi)用(yong)方(fang)便(bian)(bian),维护(hu)工作(zuo)量小,整体(ti)式(shi)(shi)(shi)滤(lv)(lv)(lv)(lv)筒比(bi)(bi)柔软的(de)(de)传(chuan)统(tong)滤(lv)(lv)(lv)(lv)袋具(ju)有的(de)(de)固定(ding)方(fang)式(shi)(shi)(shi),便(bian)(bian)于运输(shu)、安装与检(jian)修(xiu)(xiu),一人即可(ke)方(fang)便(bian)(bian)地拆(chai)装,地减少(shao)(shao)维修(xiu)(xiu)工作(zuo)量。 滤(lv)(lv)(lv)(lv)筒性(xing)能(neng)好采用(yong)脉冲、震动或逆气(qi)流清(qing)灰,都可(ke)轻易地使(shi)(shi)滤(lv)(lv)(lv)(lv)筒,清(qing)灰效果好。滤(lv)(lv)(lv)(lv)筒过滤(lv)(lv)(lv)(lv)除(chu)尘(chen)(chen)(chen)技术是袋式(shi)(shi)(shi)除(chu)尘(chen)(chen)(chen)的(de)(de)换代(dai)产品,是二十一世纪的(de)(de)过滤(lv)(lv)(lv)(lv)技术

工作原理 :正常操(cao)作,在正常操(cao)作下,含尘空(kong)气(qi)(qi)经(jing)(jing)顶部入口进入HR型(xing)除(chu)尘器,然后(hou)向下经(jing)(jing)导流板分散后(hou)通过滤(lv)(lv)芯(xin),粉(fen)尘即被阻挡在滤(lv)(lv)芯(xin)外(wai)表面上,过滤(lv)(lv)后(hou)的清洁空(kong)气(qi)(qi)经(jing)(jing)滤(lv)(lv)芯(xin)进入清洁空(kong)气(qi)(qi)室(shi),通过出(chu)口管排出(chu)。

滤(lv)筒清(qing)(qing)灰(hui),滤(lv)芯(xin)(xin)可自动地和间断地进行清(qing)(qing)灰(hui),其方式是在任一给(ji)定(ding)的时间内(nei)一组(zu)(2只)滤(lv)芯(xin)(xin)进行离线清(qing)(qing)灰(hui)。 

在滤(lv)(lv)芯清(qing)(qing)灰过程中(zhong),脉(mai)冲(chong)(chong)控制仪接(jie)通(tong)一(yi)只电磁脉(mai)冲(chong)(chong)阀(fa)的(de)(de)(de)电源,使相应的(de)(de)(de)薄膜阀(fa)喷出脉(mai)冲(chong)(chong)高(gao)压(ya)(ya)(ya)空(kong)气(qi)(qi),高(gao)压(ya)(ya)(ya)空(kong)气(qi)(qi)即(ji)从(cong)内到外(wai)穿过滤(lv)(lv)芯,将附着在滤(lv)(lv)芯外(wai)表面(mian)上(shang)的(de)(de)(de)粉尘除去(qu),尘粒落(luo)入(ru)(ru)尘斗,然后(hou)进(jin)入(ru)(ru)集(ji)灰桶。压(ya)(ya)(ya)缩(suo)(suo)空(kong)气(qi)(qi)的(de)(de)(de)压(ya)(ya)(ya)力(li)(li)调整为6kg/cm2,6kg/cm2-7kg/cm2压(ya)(ya)(ya)缩(suo)(suo)空(kong)气(qi)(qi)压(ya)(ya)(ya)力(li)(li)是可以(yi)满(man)足清(qing)(qing)灰功能(neng)(neng)要求(qiu)的(de)(de)(de)标(biao)准(zhun)的(de)(de)(de)设定值。压(ya)(ya)(ya)缩(suo)(suo)空(kong)气(qi)(qi)压(ya)(ya)(ya)力(li)(li)的(de)(de)(de)设定值越(yue)小,脉(mai)冲(chong)(chong)阀(fa)的(de)(de)(de)耗气(qi)(qi)量越(yue)小。脉(mai)冲(chong)(chong)喷吹(chui)控制仪一(yi)般(ban)可调整到每两(liang)分钟(zhong)清(qing)(qing)扫(sao)一(yi)列滤(lv)(lv)芯,即(ji)每两(liang)分钟(zhong)接(jie)通(tong)一(yi)只脉(mai)冲(chong)(chong)阀(fa),要加大清(qing)(qing)灰能(neng)(neng)量,可提(ti)高(gao)压(ya)(ya)(ya)缩(suo)(suo)空(kong)气(qi)(qi)的(de)(de)(de)压(ya)(ya)(ya)力(li)(li),但不应超过7kg/cm2。
