HCM Machinery qattiq maishiy chiqindilarni maydalash zavodi "Milliy iqlim o'zgarishi rejasi (2014-2020)" ga ko'ra, "tsement sanoati kaltsiy karbid shlaklari, qog'oz loylari, oltingugurtdan tozalash gipsi, uchuvchi kul, metallurgiya shlaklari va boshqalardan foydalanishni rag'batlantirishi kerak". sanoat chiqindilari qoldiqlari va an'anaviy ohaktosh xom ashyolari o'rniga vulqon kullari va boshqa karbonat bo'lmagan xom ashyolar.Xo'sh, qog'oz loydan qanday foydalanish kerak?Qayta ishlash texnologiyasi haqida nima deyish mumkin?
HCM Machinery qattiq maishiy chiqindilarni maydalash zavodi jamiyatning uzluksiz rivojlanishi bilan Atrof-muhitni muhofaza qilish vazirligi korxonaning "chiqindi suvlari, chiqindilari, chiqindi gazlari" ning monitoringini bosqichma-bosqich oshirganligini bilib oldi.Qog'oz ishlab chiqarish jarayonida nozik tolalar va noorganik tuzlar oqava suvlarni tozalashning birlamchi va ikkilamchi cho'kindi tanklarida loy hosil qilish uchun to'planadi va har 1000 kg qog'oz uchun taxminan 500 ~ 700 kg ho'l loy hosil bo'ladi va tarkibi murakkab va suv miqdori yuqori, uni davolash qiyin.Hozirgi vaqtda qog'oz fabrikalarining ko'pchiligi ko'pincha konsentratsiya, ekstruziya, qozon yonishi yoki poligon kabi an'anaviy usullardan foydalanadi, bu nafaqat qimmat, balki ikkilamchi ifloslanishni keltirib chiqarishi ham oson.
Tsement sanoatida qog'oz loydan qanday foydalanish kerak?Jarayon qanday?
HCM Machinery qattiq chiqindilarni tegirmoni maxsus vertikal tegirmon tarmoq ma'lumotlaridan "tsement ishlab chiqarishda loyni hamkorlikda tozalash usuli" ni o'rgandi.Ma'lumotlar tsement ishlab chiqarishda loyni birgalikda tozalash usulini ochib beradi, tsement klinkerini ishlab chiqarish uchun mavjud yangi quruq texnologik tsement klinker ishlab chiqarish liniyasidan foydalangan holda va loyni birgalikda tozalash, suv miqdori ≥70% bo'lgan qog'oz loy to'g'ridan-to'g'ri vertikalga qo'shiladi. tegirmon, tsement xomashyosi bilan aralashtirilgan, mayda silliqlash, tsement xom ashyosini olish uchun qo'shilgan qog'oz loy miqdori tsement xom ashyosining og'irligining 5% ~ 12% ni tashkil qiladi.Gomogenlashtirgandan so'ng, tsement klinkeri kuyish uchun kaltsiylash tizimiga import qilinadi.Kalsinlash tizimidagi pechning chiqindi gazi quritish uchun vertikal tegirmonga beriladi.Usul loy va tsement xomashyosini vertikal tegirmonga oldindan nisbatlash, aralashtirish va lenta tashish jarayonlari orqali qo'yishga hojat yo'q va loyni oldindan suvsizlantirish yoki quritish kerak emas.U loyni yuqori namlik bilan davolashi mumkin va qayta ishlash quvvati katta, ikkilamchi ifloslanishsiz va ohaktosh va loy kabi tsement xomashyosini tejash imkonini beradi va tsement klinkerining sifatiga salbiy ta'sir ko'rsatmaydi.
Qog'oz loyini utilizatsiya qilish uchun maydalash kerakmi?
