Sezvo tekinoroji yekuunganidza guruva inokura, nzira dzakawanda dzekuunganidza guruva dzinogadzirwa uye kuvandudzwa, nekuti zvakanakira zvemhando yepamusoro yekusefa uye yakagadzikana yakaderera kuburitsa guruva, iyobag style guruva mafiritandiyo inonyanya kufarirwa mafirita mazuvano, uye iyo pulse jet bag sefa imba ndiyo inonyanya kufarirwa mabhegi mafirita nekuda kwekuchinjika kwakafara.

Semazuva ese, kuramba mu pulse jet bag sefa imba iri pa700 ~ 1600 Pa, gare gare kushanda dzimwe nguva kwakawedzera kusvika 1800 ~ 2000Pa, asi kana ichienzaniswa nekupokana mumagetsi emagetsi precipitators (anenge 200 Pa), iyo yakazogadziriswa mutengo webhegi sefa. dzimba dzakanyanya kukwira, maitiro ekudzikisa kuramba muhombodo sefa dzimba ndiro dambudziko guru kune vanogadzira uye vashandisi vekupedzisira.

1.Zvinhu zvikuru zvinokonzera kupikisa mu pulse jet bag filter house kuwedzera
A.Kuvakwa kwebag sefa imba
Semazuva ese, zvinopikisa zvinogara zvakasiyana kana zvivakwa zvakasiyana.
Semuenzaniso, semazuva ese, dhizaini yemhepo inopinza inowanikwa pazasi peimba yebhegi uye mhepo inokwira kuburikidza neash hopper; kana iri pakati pehomwe sefa imba perpendicular kumasaga esefa. Iyo yekutanga dhizaini inogona kuita guruva mhepo yunifomu kugovera uye kudzivirira guruva mhepo kuparara zvakananga kune sefa mabhegi, uye rudzi urwu rwekugadzira nguva dzose nekushomeka kwakaderera.
Uyezve, chinhambwe pakati pebhegi kune bhegi chakasiyana, iyo inosimuka mhepo inomhanya yakasiyana zvakare, saka kuramba zvakare kwakasiyana.

B.Thesefa masaga.
Iwo mabhegi emhepo ekufambisa anogara aine kupokana, kupikisa kwekutanga kwemabhegi matsva esefa semazuva ese ari pa50 ~ 500 Pa.

C.Keke reguruva riri pamasaga esefa.
Kana iyo bhegi sefa imba ichimhanya, guruva rakaunganidzwa pamusoro pemasaga esefa, izvo zvinoita kuti mhepo iome uye iome kupfuura, saka kushorwa mubhegi sefa imba kuchawedzera, uye zvakare akasiyana guruva keke anoita kushora kwakasiyana, kunyanya. kubva pa500 ~ 2500 Pa, saka mabasa ekuchenesa / akachena ebhegi sefa imba akakosha kudzikisa kuramba.

D.Nekuvakwa kwakafanana, kupinza kwemhepo uye kubuda kwemhepo, saizi yetangi (bag house body), mavharuvhu saizi, nezvimwewo, kana kumhanya kwemhepo kwakasiyana, kushorwa kwakasiyanawo.

2.Kuderedza sei kupikisa mu pulse jet bag filter house?
A.Sarudza yakanyatsokodzera mhepo/jira reshiyo.
Mhepo / jira reshiyo = (Kuyerera kwemhepo vhoriyamu / sefa nzvimbo)
Kana iyo mhepo / jira reshiyo yakakura, pasi peimwe nzvimbo yekusefa, zvinoreva kuti mhepo yeguruva kubva pakupinza vhoriyamu yakakura, chokwadi kupikisa kuchakwira mubhegi sefa imba.
Semazuva ese, kune pulse jet bag sefa imba, iyo mhepo / jira reshiyo iri nani isapfuure 1m/min, kune imwe yakanaka particles kuunganidzwa, mhepo / jira rinofanirwa kudzora kunyange kuderera kana kuramba kuchiwedzera zvakanyanya, asi pakugadzira, mumwe mugadziri. vanoda kuita bhegi sefa imba yavo kukwikwidzana pamusika (udiki saizi, yakaderera mutengo), vanogara vachiedza kuzivisa yakakwira zvakanyanya mhepo / jira reshiyo, mune iyi kesi, kushorwa mune idzi bhegi sefa imba chokwadi ichaita padivi repamusoro.

B.Dzora kumhanya kwemhepo nekukwira kwakakodzera.
Kusimuka kwemhepo kunoreva kumhanya kwemhepo munzvimbo yebhegi kuenda kubhegi, pasi pehumwe vhoriyamu yekuyerera kwemhepo, kukwira kwemhepo inokwira zvinoreva kukwira kwehunyambiri hwemasaga esefa, kureva kuti chinhambwe chiri pakati pemasaga esefa chidiki, uye saizi yebhagi sefa imba idiki zvakare kana ichienzaniswa neyakakodzerwa dhizaini, saka yakakwira yekukwira kwemhepo inomhanya iyo inowedzera kushorwa mubhegi sefa imba. Kubva pane zvakaitika, kumhanya kwemhepo kukwira kuri nani kudzorwa nezve 1m/S.

C．Kumhanya kwemhepo kunofanirwa kudzorwa zvakanaka munzvimbo dzakasiyana dzebhegi sefa imba.
Kupokana kuri mubhegi sefa imba zvakare kunokanganisa nekumhanya kwemhepo kumhepo inopinza uye yekubuda, mavharuvhu ekuparadzira emhepo, poppet mavharuvhu, bhegi tube sheet, yakajeka imba yemhepo, nezvimwe, semazuva ese, pakugadzira bhegi sefa imba, tinofanira. edza kuwedzera mhepo inopinza uye yekubuda, shandisa mavharuvhu makuru ekugovera uye mavharuvhu makuru epoppet, nezvimwewo, kuti uderedze kukurumidza kwekuyerera kwemhepo uye kuderedza kuramba mubhegi sefa imba.
Kuderedza kuyerera kwemhepo muimba yakachena yemhepo zvinoreva kureba kweimba yebhegi inoda kuwedzera, chokwadi icho chichawedzera zvakanyanya pamutengo wekuvaka, saka tinofanira kusarudza mhepo yakakodzera yekuyerera kwemhepo ini ikoko, semazuva ose, mhepo inoyerera inomhanya mukati. imba yakachena yemhepo inofanira kudzorwa pa 3 ~ 5 m / S.
Kumhanya kwemhepo kubhegi chubhu yepepa inoenzana nehurefu hwebhegi kureba/dhayamita yebhegi. Iyo dhayamita imwechete, kureba kureba, kumhanya kwemhepo pabhegi chubhu pepa kunofanirwa kunge kwakakwira, izvo zvichawedzera kuramba mubhegi sefa imba, saka kukosha kwe (kureba kwebhegi / dhayamita yebhegi) semazuva ese kunofanirwa kudzorwa kusapfuure makumi matanhatu, kana kupikisa kunofanirwa kunge kwakakwira, uye kuchenesa bhegi kunoshandawo zvakaoma kugadzirisa.

D．Ita kugovera kwemhepo kuenzana nemakamuri ebhegi sefa imba.

E.Kuvandudza mabasa ekuchenesa
Iyo guruva keke pamusoro pemasaga esefa chokwadi ichaita kuti kushorwa muimba yebhegi kuwedzere, kuitira kuchengetedza kupikisa kwakakodzera, isu tinofanirwa kuchenesa mabhegi emasefa, kune iyo pulse jet bag sefa dzimba, ichashandisa yakakwira yekumanikidza mweya. kupuruzira jet kumabhegi ekusefa uye kuita kuti keke yeguruva idonhe kune hopper, uye basa rekuchenesa rakanaka kana kuti risingaiti rine chekuita nekuchenesa mweya wemhepo, kutenderera kwakachena, kureba kwemasaga emasefa, chinhambwe pakati pebhegi kuenda kubhegi zvakananga.
Mhepo yekuchenesa haigone kuderera zvakanyanya, kana guruva harizodonha; asi zvakare haigone kukwira zvakanyanya, kana mabhegi esefa anofanirwa kuputswa nekukurumidza uye anogona kukonzera guruva kudzoreredzwa, saka kudzvanywa kwemhepo yekuchenesa kunofanirwa kudzorwa munzvimbo yakakodzera zvinoenderana nehunhu hweguruva. Semazuva ese, kudzvanywa kunofanirwa kudzorwa pa 0.2 ~ 0.4 Mpa, kazhinji, isu tinofunga chete kana kumanikidza kuchigona kuita kuti mabhegi esefa achene, kudzika kuri nani.

F.Dust Pre- collection
Kupokana kwebhegi sefa imba zvakare ine chekuita neguruva remukati, yakakwira guruva remukati keke yeguruva inovaka nekukurumidza pamusoro pemabhegi emasefa, chokwadi kupokana kuchawedzera nekukurumidza, asi kana ichigona kuunganidza imwe guruva pamberi. ivo vanoenda kubhegi sefa imba kana kubata nemasaga esefa, ayo ane chokwadi anobatsira kurebesa nguva yekuvaka keke, saka kuramba hakuzowedzerwe nekukurumidza.

Nzira yekuita sei guruva risati raunganidza? Nzira dzacho dzakawanda, semuenzaniso: kuisa dutu rekusefa mhepo yeguruva isati yapinda muhomwe sefa imba; ita kuti mhepo ipinde kubva pasi peimba yebhegi, saka zvikamu zvakakura zvichadonha kutanga; kana iyo inopinza iri pakati pebhegi sefa imba, saka inogona kuisa guruva inobvisa baffle kuti itungamire mhepo kubva pasi nedivi remba yebhegi kuitira kuti zvimwe zvimedu zvakakura zvidonhe kutanga, zvakare zvinogona kudzivirira guruva remhepo kuparara. mabhegi ekusefa zvakananga, uye anogona kurebesa hupenyu hwesevhisi yemabhegi emasefa.
