Pulp Concentration Measurement
Iyo pulp concentration mubhokisi yemuchina inosvika 2.5-3.5% kazhinji. Mvura inodiwa kudzikisa pulp kusvika kune yakaderera yekumisikidza kune yakanyatso pararira fiber uye kubviswa tsvina.
Forfourdrinier michina, iyo pulp concentration inopinda mesh ndeye 0.3-1.0% mune yakajairwa zvinoenderana neiyo pulp maitiro, zvivakwa zvemidziyo, uye mhando yepepa. Panguva ino, mwero wedilution unoenderana neinodiwa pulp concentration pamesh, zvichireva kuti iyo imwechete yekumisikidza inoshandiswa kucheneswa, kusefa, uye kugadzira pamambure.
Iyo pulp yekumisikidza pamambure yakadzikira kusvika 0.1-0.3% chete kumichina yemacylinder. Kuyerera kweyero kuburikidza nekucheneswa uye kusefa kwakakwira kupfuura zvinodiwa neiyo yakaderera-concentration pulp. Uyezve, mamwe maturusi ekuchenesa uye kusefa anodiwa kugadzirisa iyo yakaderera-yakadzika pulp, inoda mari yakawanda, nzvimbo yakakura, mapaipi akaomarara, uye mashandisiro esimba rakawanda.
Michina yemacylinder inowanzotora amaviri-nhanho dilution process,umo kusungirirwa kunodzikiswa kusvika ku0.5 ~ 0.6% kutanga kwekucheneswa kwekutanga uye kusefa; yobva yadzikiswa kunonangwa kumberi mberi isati yapinda pamambure mubhokisi rekudzikamisa.
Pulp dilution inoshandisa mvura chena kuburikidza nemesh mune yakajairwa kuchengetedza mvura uye kudzoreredza mafibers akanaka, mafirita, uye makemikari kubva mumvura chena. Kudzoreredza kwemvura chena kunobatsira kuchengetedza simba kumichina inoda kupisa pulp.
Zvinhu Zvikuru Zvinokanganisa Diluted Pulp Concentration
Kusiyana kwePulp Concentration Kupinda muBhokisi Rinodzora
Kuchinja-chinja kwekusagadzikana kubva pakurohwa kana shanduko mune yakaputsika system inogona kukonzera mutsauko mukusungwa kwe pulp. Kusafamba zvakanaka mumabhokisi emuchina kunogona kutungamira mukusawirirana kwe pulp munzvimbo dzakasiyana, zvichikonzera kusagadzikana kwakawedzera.
Kudzokera shure kweKurambas muKucheneswa uyekusefa
Kurambwa kubva mukucheneswa uye kusefa kunowanzo kudzoserwa muhurongwa nemvura yekudiridza. Kusiyana kwevhoriyamu uye kusungirirwa kwekuramba uku kunoenderana nekuita kwekuchenesa uye kusefa michina uye mazinga emvura papombi inlets.
Shanduko idzi dzinoburitsa zvinokonzeresa pamvura chena inoshandiswa kunyungudutsa uye, zvakare, iyo yekupedzisira pulp concentration. Nyaya dzakafanana dzinogona kuitika mumasisitimu ekudzoka emasilinda emuchina anofashukira matangi.
Misiyano yekumisikidzwa yakanyungudutswa pulp inogona kukanganisa zvese kushanda kwemushini wemapepa uye yekupedzisira bepa mhando. Naizvozvo, zvakakosha kunyatso tarisisa pulp concentration nekuenderana mita pulpyakagadzirwa naLonnmeterpanguva yekugadzira uye gadzirisa iyo inflow kubhokisi rekutonga kuti uchengetedze kugadzikana kwakagadzikana. Michina yemapepa yemazuva ano inowanzo shandisa zviridzwa otomatiki ku:
- Gadzirisa otomatiki iyopulp concentrationkupinda mubhokisi rekuraira.
- Gadzirisa iyo inopinda zvichienderana nekuchinja kwebepa hwaro huremu uyeheadbox pulp concentration.
Izvi zvinovimbisa yakagadzikana pulp concentration.
Bets of Concentration Adjustment for Diluted Pulp
Concentration regulation ye diluted pulp mabhenefiti kune ese ari maviri akanyanya kushanda kwebepa muchina uye mapepa emhando yekuchengetedza.

Kana pulp ine yakaderera kurova dhigirii uye dewaters nokukurumidza, mukati uye kunze kwemvura mazinga ari mesh chikamu akaderedzwa, kushaya simba kubatanidzwa kwepepa layer kune mesh. Izvi zvinowedzera iyo yekusimbisa mhedzisiro, inoderedza kufashukira, uye inowedzera kukurumidza mutsauko pakati pepulp uye mesh, zvichitungamira kune isina kuenzana kuumbwa kwepepa.
Kuti ugadzirise izvi, kushandiswa kwemvura chena kunowedzerwa kudzikisa kudzika kwe pulp, kuwedzera kuyerera kwemesh. Izvi zvinosimudza mutsauko wehuwandu hwemvura, inowedzera kufashukira, inoderedza mhedzisiro, uye inoderedza kukurumidza mutsauko, nekudaro ichivandudza sheet kufanana.
YeFourdrinier Machines
Madhigirii ekurova madhigirii anoita kuti mvura iome, wedzera mutsetse wemvura, kuwedzera hunyoro mune pepa rakanyorova, uye zvinotungamira kune embossing kana kupwanya panguva yekudzvanya. Pepa kunetsana pamushini kunoderedza, uye shrinkage panguva yekuomeswa kunowedzera, zvichikonzera kuremara senge kupeta uye kuunyana.
Kukunda matambudziko aya, diluted pulp concentration inogona kuwedzerwa nekudzikisira kushandiswa kwemvura chena, kuderedza nyaya dzemvura.
Sezvineiwo, kana dhigirii rekurova rakaderera, mafibhi anowanzo kuyerera, uye mvura inoitika nekukurumidza pamambure, zvichikanganisa kufanana kwepepa. Muchiitiko ichi, kuwedzera kushandiswa kwemvura chena kudzikisa diluted pulp concentration kunogona kuderedza flocculation uye kunatsiridza kufanana.
Mhedziso
Dilution ibasa rakakosha mukugadzira mapepa. Mukugadzira, zvakakosha kuti:
- Nyatsotarisisa uye kunyatso dzora shanduko mu dilutedpulp concentrationkuve nechokwadi chekuita kwakagadzikana.
- Teerera kune shanduko yemhando yechigadzirwa uye mamiriro ekushandauye, pazvinenge zvichidikanwa, gadzirisa kuisa pfungwa pa pulp sechombo chekukunda matambudziko akaita seataurwa pamusoro.
Nekunyatso gadzirisa pulp dilution, kugadzirwa kwakagadzikana, mapepa emhando yepamusoro, uye kushanda kwakakwana kunogona kuwanikwa.
