Ndezvipi zvakanakira mota dzeLNG zvichienzaniswa nemotokari dzeCNG?

Maitiro e Chirimwa chidiki cheLNG (chirimwa chidiki cheLNG) zvinosanganisira zvikamu zvina sezvinotevera.

Mota yeLNG ndeimwe yeinonyanya kushandiswa pakugadzira mafuta eLNG.

(1) Tsanangura muchidimbu maitiro ekuzadza mota dzeLNG uye kupihwa kwemafuta.

Mhinduro: Kuzadza kwemvura: LNG inoyerera kubva pachiteshi chekuzadza ichienda pamusoro petangi rekuchengetera zvinhu kuburikidza nevharuvhu ine nzira imwe chete. Gasi riri mukati metangi rinoita zvidimbu, uye kumanikidzwa kunodzikira. Kana razadzwa kusvika padanho remvura rakatarwa, rinomira roga;

Kuwanikwa kwegasi: Kana injini yatanga, vharuvhu yesolenoid inovhurika, uye LNG inobuda pasi pekumanikidzwa mukati metangi, inopinda muvaporizer kuti ishandurwe kupisa uye gasification, uye inoendeswa kuinjini.

(2) Ndezvipi zvakanakira mota dzeLNG zvichienzaniswa nemotokari dzeCNG?

Mhinduro: LNG ine simba rakawanda (rinopetwa katatu kupfuura CNG), inogona kutyaira daro refu rinodarika 400km, uye inoshandisa simba shoma uye ine utsi hushoma.

(3) Ndezvipi zvakanakira mota dzeLNG kana tichienzanisa nemotokari dzedhiziri?

A. Kuchengetedza Mari. 1m3 LNG yakaenzana ne625N m3 yegasi rechisikigo. Kushanda kwemotokari dzedhiziri dzine simba remabhiza rimwe chete kunoratidza kuti 1m3 yegasi rechisikigo yakaenzana ne1 litre ye0 # diesel, uye mutengo we1m3 wegasi rechisikigo ungangoita 5.2 yuan yepeturu, inova 70% yemutengo we1 litre ye0 # diesel (7.24 yuan). Izvi zvinoreva kuti kuchinja kushandisa gasi rechisikigo kumotokari dzedhiziri dzine simba remabhiza rimwe chete kunogona kuchengetedza 30% yemutengo. Makiromita ekushanda pagore anoverengerwa zvichienderana ne70000 makiromita (kushandiswa kwemafuta pamakiromita zana kunoverengerwa zvichienderana ne50 litres yedhiziri kana 50m3 yegasi rechisikigo), izvo zvinogona kuchengetedza 71000 yuan mumitengo yemafuta.

B. Kushanda zvakanaka kwekuchengetedza. LNG ine poindi yekupisa ye650 ℃, yakakwira kupfuura dhiziri nepeturu, uye yakaoma kuibatidza kupfuura peturu nedhiziri. Muganho wekuputika kweLNG i5% -15%, uye huwandu hwemhepo mushure mekugadzirwa kwegasi hunongova hafu yemhepo, saka chero bedzi paine kubuda kwemvura, ichabva yangopera uye inopararira. Kumanikidzwa kwekuchengetera LNG kwakaderera (0.3-0.7MPa), zvichiita kuti ive yakachengeteka kupfuura CNG.

C. Kudzivirirwa kwezvakatipoteredza. Nekuda kwekugadzirwa kwayo kwakachena uye kusviba kushoma, mota dzeLNG dzinoburitsa magasi asina kukuvadza akadai seSO2, NOX, uye CO2, ayo anobatsira pakuchengetedzwa kwezvakatipoteredza.

D. Yakavimbika. LNG ine simba rakanaka rekutanga pakupisa kushoma uye inogona kuchengetedza mafuta akawanda munguva dzekupisa kushoma. LNG ine simba rakawanda, uye marori makuru eLNG anogona kufamba makiromita 800 kusvika 1000 nguva dzose achiisa mafuta kamwe chete, izvo zvinogona kusangana nezvinodiwa zvekufambisa kure. Manyuko egasi reLNG akakwana uye anogona kutakurwa nedaro refu uchishandisa marori etangi akatsaurirwa, pasina kudziviswa nemapaipi egasi rechisikigo.

E. Kugadziriswa kwemotokari yeLNG. Huwandu hweoctane yegasi rechisikigo hwakakwira kusvika ku130, uye mashandiro ayo ekudzivirira kugogodza akanaka. Mushure mekushandurwa kwemotokari, hupenyu hweinjini hunogona kuwedzerwa kanopfuura kaviri, uye mari yekuchengetedza inoenderana inogona kuderedzwa neanopfuura 50%. Tekinoroji yekuchinja yemuno iripo yakura, uye mari inowanikwa inowanzo wanikwa mukati memwedzi mitanhatu mushure mekushandurwa. Kugadziriswa kwemotokari dzeLNG kunogona kuitwa nenzira mbiri: imwe ndeyekuvakazve injini yedhiziri iripo kuita injini yegasi rechisikigo uye kuisa sisitimu yekugovera gasi yeLNG; Yechipiri ndeyekutenga mota dzeLNG zvakananga. Injini iyi yakashandurwa nekambani yehunyanzvi, ichishandura injini yemotokari yekutanga kuita injini imwe chete yemafuta. Mushure mekushandurwa, injini inogona kusvika padanho rehunyanzvi reinjini itsva, ine hupenyu hwemakiromita 500,000.
