Guruva ndicho chimwe chezvikonzero zvikuru zvinotadzisa kuita zvakanaka, kwakachengeteka uye kwakachena kugadzirwa kwemugodhi wemugodhi. Ore kubva pakutakura, kutakura, kupwanya, kuongorora uye kupinda mumusangano wekugadzira uye mamwe maitiro anogona kuburitsa guruva, saka simbisa kugadzirwa kwemaitiro ekuvandudza ndiyo nzira huru yekudzora kupararira kweguruva, kubvisa kukuvadza kweguruva, uye wozowana kugadzirwa kwehushamwari. zvinangwa.
Iyo inokonzeresa kuongororwa kweguruva inogona kukamurwa kuita marudzi maviri zvichienderana nenzira yekugadzira guruva uye inducing zvinhu:
Kutanga, mukugadzirisa zvinhu zvakawanda, kuyerera kwemhepo kunowedzera zvakanyanya, uye ipapo iyo yakanaka granular zvinhu zvinobudiswa kuita guruva (guruva);
Chechipiri, nekuda kwekushanda kwemidziyo mumusangano wekugadzira, kufamba kwemhepo yemukati kunowedzera zvakanyanya, izvo zvinoita kuti guruva remukati risimudzwe zvakare (secondary dust).
Iyo huru huru inonyanya kugoverwa mumusangano wekupwanya, uye zvinokonzeresa kugadzirwa kweguruva zvinosanganisira:
① Hupfu hunokonzerwa nekuveura: ore inowira mubhini remugodhi kubva pakakwirira, uye hupfu hwakatsetseka hunoonekwa huchiveura pasi pechiito chemhepo-yekupikisa, uye yobva yayangarara mukumiswa. Iyo yakakura kureba kwezvinhu zvinowira, iyo yakakura kukurumidza kwehupfu hwakatsetseka, uye zvakanyanya kuoneka guruva.
(2) Induced air dusting: Kana zvinhu zvacho zvichipinda mubhini remugodhi padivi pemusuwo, zvinhu zvacho zvine kumwe kumhanya panguva yekudonha, izvo zvinogona kutyaira mweya wakatenderedza kuti ufambe nezvinhu, uye nekukasira kukurumidza kwekuyerera kwemhepo. inogona kutyaira zvimwe zvinhu zvakanaka kumisa uye kuumba huruva.
(3) Hupfu hunokonzerwa nekufamba kwemidziyo: muchirongwa chekuongorora zvinhu, midziyo yekuongorora iri mukufamba kwepamusoro-soro, iyo inogona kuita kuti mineral powder mu ore isanganise nemhepo uye iite guruva. Mukuwedzera, zvimwe midziyo yakadai semafeni, motors, nezvimwewo, inogona kukonzera guruva.
(4) Hupfu hunokonzerwa nekutakura zvinhu: guruva rinokonzerwa nekusvina zvinhu mukati mekugadzirisa bhini remugodhi rinoparadzirwa kunze kubva pachiteshi chekuchaja.
Dust control nzira yekupwanya uye kuongorora Dust control nzira yekupwanya uye kuongorora mumigodhi yekugadzira migodhi inonyanya kusanganisira:
Yekutanga ndeyekudzikisa guruva remukati muchirimwa chekusarudza zvakanyanya sezvinobvira, kuitira kuti guruva remukati rinosangana nezvinodiwa zvakakosha zvezviyero zvinoenderana nenyika;
Chechipiri ndechekuona kuti iyo exhaust guruva inosangana nezvinodiwa yenyika.
01 Yakavharwa mhepo yekubvisa huruva nzira yekudzivirira
Guruva riri mumugodhi wekusonga chirimwa rinonyanya kubva muwekishopu inobata nemidziyo yakawanda yesimbi, uye kupwanya kwayo, kuvheneka nemidziyo yekufambisa ndiyo manyuko ehuruva. Nokudaro, nzira yakavharwa yekubudisa mhepo inogona kushandiswa kudzora uye kubvisa guruva mumusangano, zvikonzero zvinosanganisira: kutanga, inogona kunyatso kudzora kupararira kwekunze kweguruva, uye yechipiri ndeyokupa mamiriro ezvinhu ekutanga ekubvisa mhepo uye kubvisa guruva.
(1) Kuiswa chisimbiso kwemidziyo inogadzira guruva panguva yekuitwa kwekuvhara kwemhepo yakavharwa uye kudzivirira guruva kwakakosha, uye ndiyo hwaro hwekudimbura kukurumidza kupararira kweguruva rimwechete.
(2) Iyo idiki hunyoro hwezvinhu, iyo yakakura huwandu hweguruva hunogadzirwa mukupwanya. Kuti uvandudze mhedzisiro yekubvisa mhepo uye kudzivirira guruva, zvinodikanwa kuvhara maburi ekupinda nekubuda kweiyo crusher, uye kuseta iyo yekuburitsa hood mune inopinza chute kana yekudyisa kuti inyatso kuvandudza guruva rekubvisa. (3) Izvo zvinhu zvinofamba zvichitevedza chidzitiro chepamusoro panguva yekuongorora, izvo zvinogona kuita kuti iyo yakanaka uye inonyura mhepo isanganise kuita guruva, saka mudziyo unogona kugadzirwa muchinhu chakavharika chakavharwa, ndiko kuti, iyo vibrating skrini yakavharwa. , uye chivharo chekubuda kwemhepo chinoiswa pachiteshi chekuburitsa chepamusoro pechiso, icho chinogona kunyatsobvisa guruva muchiratidziro chinozunguza.
Iyo yakakosha tekinoroji yekuvharwa kubviswa kweguruva ndeyekuisa yakavharwa chivharo cheguruva munzvimbo huru yekugadzira guruva, zvinobudirira kudzora guruva sosi, uyezve kuburikidza nesimba re fan mumhepo yekubvisa midziyo, guruva rinonyudzwa muvhavha yeguruva, uye mushure mekugadzirisa guruva rekuunganidza, rinobudiswa kubva paipi inoenderana. Naizvozvo, muunganidzi weguruva ndicho chikamu chikuru chemaitiro, uye kusarudzwa kunofanirwa kufunga nezve zvinotevera pfungwa:
(1) Mamiriro egasi anofanira kubviswa anofanirwa kutariswa zvizere, kusanganisira hunyoro, tembiricha, guruva, ngura, nezvimwewo;
(2) Zvimiro zveguruva zvinofanirwa kutariswa zvakazara, senge guruva kuumbwa, particle size, corrosion, viscosity, kuputika, chaiyo giravhiti, hydrophilic, heavy metal yemukati, nezvimwe.
③ Izvo zvinodiwa kuti utarise zviratidzo zvemhando yemhepo zvinodiwa mushure mekushanduka, senge guruva riri mumagasi.
02 Nzira yekudzivirira huruva yakanyorova
Wet dust control ndiyo inonyanya kushandiswa nzira yekubvisa guruva, iyo inowedzera humidity ye ore zvinhu nekupfapfaidza mvura mukuita ore zvinhu kutakura, kupwanya uye kuongorora, zvisina kunanga kuwedzera humidity, chaiyo giravhiti uye viscosity yezvinhu zvakanaka, kuitira kuti zvakanaka. zvinhu hazvisi nyore kusanganiswa nemhepo kugadzira guruva; Kana kupfapfaidza guruva rakagadzirwa panzvimbo yeguruva, kuitira kuti guruva remhepo rinyure nekuda kwekuwedzera kwehunyoro, kuitira kuti uwane chinangwa chekubvisa guruva.
Kuenzaniswa nekubviswa kweguruva rekupfapfaidza, kupfapfaidza guruva kubviswa (ultrasonic atomization guruva kubviswa) inzira iri nyore uye ine hupfumi, uye mhedzisiro yacho yakanaka, inonyanya kuumbwa nezvikamu zviviri: imwe ndiyo yekupfapfaidza system (atomizer, electric ball valve, mvura yekupa mudziyo. uye kuumbwa kwepombi), imwe yacho ndiyo yemagetsi control system.
Kuti uvandudze kunaka uye mhedzisiro yekubvisa guruva rekupfapfaidza, iyo spray system inofanirwa kutarisisa kune anotevera mapoinzi:
① Mhute yemvura inoshandiswa pakubvisa guruva inofanirwa kusangana nezvinodiwa zvekubvisa guruva zvakanyanya, uye kuchengetedza pamusoro pebhandi rekutakura uye dzimwe nzvimbo dzakanyorova sezvinobvira, ndiko kuti, kuve nechokwadi chekuti mhute yemvura inovhara iyo. huruva pachiteshi chengarava zvakanyanya sezvinobvira.
② Inofanirwa kutarisisa kuwanda kwemvura yekupfapfaidza, izvi zvinodaro nekuti mvura iri muore inowedzera zvakanyanya, izvo zvine chekuita nekutarisa maitiro, saka, mvura iri mumhute yemvura inofanirwa kudzorwa mukati meiyo ore. mvura yakawedzera ne 4%, iyo inogona kudzivirira zvinobudirira dambudziko rekuvhara pombi.
③ Iyo yekupfapfaidza sisitimu inofanirwa kuve yakavakirwa pane otomatiki michina, isina manyorero ekutonga kushanda.
Kune akawanda masosi eguruva mumigodhi, saka iyo organic musanganiswa wekuvharwa kwemhepo kubviswa uye kupfapfaidza guruva kubviswa kunogona kugamuchirwa. Mukuwedzera, kurapwa kwekubvisa guruva kunoda kuchengetedza zviwanikwa zvemvura, zviwanikwa zvemagetsi uye zvichingodaro, ndiko kuti, pasi peiyo guruva rekubvisa mhedzisiro, sezvinobvira kuchengetedza mutengo wekubvisa guruva.
