Kutulutsa madzi kwa Sludge
01
Sludge mankhwala lamba fyuluta atolankhani mchenga kutsuka kumunda matope dewatering zida

Zogulitsa Zamankhwala
1) Makina osindikizira a sludge dewatering belt ali ndi malo apadera komanso aatali owoneka ngati mphero kuti atsimikizire kugwira ntchito mokhazikika.
2) Kutaya madzi m'thupi kumakhala ndi malo akuluakulu, mphamvu zopangira mphamvu, mphamvu zazikulu zolemetsa, kugwiritsa ntchito mphamvu zochepa, komanso ntchito zotsika mtengo.
3) Mipikisano yodzigudubuza imachepa ndipo kapangidwe kake kamakhala kakang'ono, komwe kumawonjezera zolimba za keke ya fyuluta.
4) Njira yatsopano yosinthira yokhayokha imathandizira kwambiri moyo wautumiki wa lamba wa fyuluta.
5) Gwiritsani ntchito machitidwe awiri odziyimira pawokha.

Zosefera zikugwira ntchito
Ntchito yonse ya makina osindikizira a lamba akhoza kugawidwa m'magawo atatu: sludge flocculation, sludge flocculation, gravity fyuluta atolankhani kusefera, mphamvu yokoka madzi m'thupi, ndi Finyani madzi m'thupi / kutaya madzi m'thupi.
1) Sludge flocculation
Pamaso sludge ndi dewatered, ayenera choyamba kudutsa ndondomeko flocculation. Flocculation amatanthauza kugwiritsa ntchito flocculant (ie polima, polima electrolyte) kuchiza kuyimitsidwa. Pambuyo pa flocculant imasakanizidwa ndi sludge, tinthu tating'onoting'ono tomwe timayimitsidwa Njirayi imapangitsa kuti zomatira zikhale condensate ndikulekanitsa magawo olimba ndi amadzimadzi. The sludge ndi flocculated mu flocculation riyakitala, ndi okhala nthawi ya sludge mu flocculation riyakitala ndi za 1 mpaka 3 mphindi.
2) Kuchepetsa mphamvu yokoka
Kupyolera mu flocculation, mphamvu yokoka madzi m'thupi thickener ikuchitika pamene sludge chinyezi okhutira ndi 99.3%. Chinyezi chamatope chimatha kufika 95-98%. Pofuna kuchepetsa kusungunuka kwa sludge musanayambe kukanikiza, madzi ambiri aulere ayenera kuyandama ndikuchotsa mphamvu yokoka. Zone amazindikira izi. The sludge mu thumba fyuluta sichimakhudzidwa ndi mphamvu zakunja. Gawo la sludge load lamba wa fyuluta lili ndi ngodya inayake. Ndi kugunda kwapakati pakati pa lamba wosefera ndi madzi amatope, lamba wa sefa yamatope amakokera mzerewo mmwamba ndi pansi. , pali njira ya madzi owunjikana matope, omwe amatalikitsa nthawi yokoka ya kutaya madzi m'thupi, zomwe zimathandiza kuti madzi atuluke atuluke. Dothi limabwerera kukafinya thumba la fyuluta kumbali yakumbuyo ndikulowetsa ma compactor awiri. Imagwira ntchito mwachisawawa mu fyuluta imodzi. Ntchito yake ndikukhuthula matope ndikugawa mofanana pamwamba pa lamba wa fyuluta kuti awononge madzi ambiri.
3) Kupondereza ndi kutaya madzi m'thupi
Dothi lopanda madzi ndi mphamvu yokoka. Lambawo akamasuntha, amalowa m'gawo lopondereza lokhala ngati mphero pakati pa malamba a fyuluta, pomwe amakanikizidwa ndikusowa madzi. Gawo la madzi aulere pamwamba pa sludge limachotsedwa, ndiyeno limalowa mu gawo la "S" la ma rollers asanu ndi awiri. Chifukwa cha The kuchepetsa matope ndi kupinda kukameta ubweya mphamvu kwaiye angapo mamasukidwe akayendedwe mphamvu pakati pa fyuluta malamba Finyani kunja madzi ufulu mkati.

Mapulogalamu
Kusindikiza ndi utoto sludge, electroplating sludge, papermaking sludge, mankhwala sludge, masewage sludge, matope sludge, heavy metal sludge, chikopa sludge, kubowola sludge, sludge mowa, matope chakudya.
