Unit configuration

(1) Chikamu chekubvisa mvura mumuviri chakaiswa skid, uye midziyo yemagetsi uye zviridzwa zviri paskid zvinodzivirira kuputika.

(2) The dehydration unit inoiswa mumba.Mutengesi achagadzira iyo yakakodzera sisitimu zvinoenderana neyakaderedzwa tembiricha nharaunda munguva yechando kuti ave nechokwadi chekushanda kwakajairika kweiyo dehydration unit munguva yechando.

(3) Mapombi ese akabatanidzwa kune skid side, uye ese ekuchengetedza valve vent pombi uye blowdown pombi akabatana kudivi reskid kuburikidza nezvakawanda.

(4) Ichakwanisa kushanda zvakanaka pasi pemamiriro akanyorwa mune data data.

(5) Ese maflange achabatanidzwa nemuridzi achafananidzwa butt welding flange ine gasket, bhaudhi uye nati.Iyo flange chiyero ndeye Hg / t20592-2009, iyo flange inotora RF kumeso, B yakatevedzana, uye zvinhu i16Mn;iyo spiral ronda gasket standard ndeye Hg / t20610-2009, giredhi rekumanikidza rakafanana neflange, gasket inotora spiral ronda gasket nemhete yemukati uye mhete yepakati, mhete yepakati isimbi kabhoni, zvinhu zvesimbi bhandi uye yemukati. mhete ndeye 0Cr18Ni9, iyo yekurongedza inochinjika graphite bhandi;iyo stud yakakosha-chinangwa yakazara shinda stud (35CrMo), maererano neHg / t20613-2009;iyo nzungu ndeye II hex nut (30CrMo), maererano neGB / t6175.

(6) Iyo yekuvandudza maitiro ndeye yakaenzana kumanikidzwa yakavharwa kutenderera nekunze kwemagetsi kupisa.

(7) Iyo sefa yakashongedzerwa pane inopinza ine sefa yechokwadi ≤ 10 μ m, iyo inogona kunyatso dzivirira iyo adsorbent kubva pakunyorova uye kusvibiswa nemvura uye kuwedzera hupenyu hwebasa reiyo adsorbent;iyo guruva sefa inoshongedzerwa pakubuda nesefa kurongeka kwe3 μ m, iyo inogona kuchengetedza yakajairika kushanda kweanotevera compressors.

(8) Iyo yekuvandudza sisitimu inotora iyo yekutenderera compressor kutyaira kutenderera kudzoreredzwa, uye yekuvandudza sisitimu inoshongedzerwa negasi mvura yekuparadzanisa kuti iite kutenderera kutenderera gasi kuchena.

(9) Iyo gasi-mvura inoparadzanisa ine kaviri kupatsanurwa kwesimba rinokwevera uye kusefa, ine yakanaka yekuparadzanisa mhedzisiro.Tangi yekuchengetera mvura inoiswa kuseri kwegasi-mvura yekuparadzanisa ine mvura yekuchengetera vhoriyamu ye0.05m3 kusangana nekubuda kwese kwekuzvarwa patsva.

(10) Kudzora sisitimu: PLC chirongwa chekudzora chinosanganisira kugara tembiricha kutonga uye kubata skrini.Mushure mekunge iyo control parameter yekupinda yagadziriswa, inozoratidzwa paLCD skrini, uye chirongwa chakaseti chinozodzora otomatiki mashandiro akajairwa ekutenderera fan, heater, inotonhorera uye anti kutonhora uye kupisa kuchengetedza mudziyo.Yakashongedzerwa nechiridzwa chemuno uye indoor control chiridzwa, pamwe neremote control chiridzwa.Kutanga uye kumira kwekuvandudza kutonhora, kutenderera booster uye heater yemagetsi inogona kuona magetsi ekuvhara kudzora uye bhuku rakazvimirira kudzora, uye manyorero ekutonga anosarudzwa.Multi point tembiricha sensor yekutarisa, kuratidzwa kwakaringana uye kutonga kweheater yekubuda, kuvandudza gasi rekubuda uye inotonhorera yekubuda tembiricha, kudzora paramita yekupinda kuPLC yepakati processor yekugadzirisa, uye kutonga chiito chekuvandudza system zvinoenderana nechirongwa chakaiswa, uye yakashongedzerwa nekutaurirana kure. interface, RS485 interface, kutaurirana protocol ndeye MODBUS-RTU.Heater overheat yekudzivirira switch, dzivirira heater yakaoma kupisa, chengetedza magetsi ekudziya ehupenyu hupenyu.

(11) Iyo PLC inodzora kabati yakarongedzerwa mukamuri yekugovera magetsi muchiteshi, uye iyo PLC yekudzora kabati ichave ine maheater emuchadenga kuti ive nechokwadi chekushanda kwakajairwa kwenzvimbo yakaderera tembiricha munguva yechando.

(12) Basa rekuchengetedza kuchengetedza: iyo heater barrel uye yekubuda inopihwa tembiricha yekudzivirira basa;iyo mota inopiwa nekudzivirira kwekupisa uye kupfupika kwedziviriro yedunhu, uye iyo yemagetsi sisitimu inopihwa pfupi pfupi uye kudzivirirwa kwekudzivirira.

(13) Motokari inotora moto usingapindi moto asynchronous, chiyero chekuputika-chinoputika hachisi pasi peExd Ⅱ BT4, chiyero chekudzivirira chemidziyo yemagetsi haisi pasi pe IP54, uye chiyero chekudzivirira chechiridzwa chemunda hachisi pasi pe IP55.

(14) Mhepo inotonhorera: chubhu fin heat exchanger

Kugadziriswa kwechimiro

(1) Mushure mekunge adsorption shongwe yakaputirwa nemafuta ekudzivirira, inoputirwa nealuminium yekushongedza ndiro, ine yakanaka corrosion resistance uye kutaridzika kwakanaka.

(2) Iyo yemagetsi yekudziya chubhu ndeye yakakosha mhando, yakagadzirwa nesimbi isina tsvina 1Cr18Ni9Ti.Iyo yekupisa simba pamusoro peiyo yemagetsi kupisa chubhu inosvika 2.0w/cm 2.

(3) Dew point analyzer sampling port inoiswa panzvimbo yekubuda kwedehydration unit.Yakashongedzerwa neinternet dova point mita.

(4) Iyo adsorption tower inoshongedzerwa nenharaunda yekuratidzira pressure gauge uye thermometer kuratidza kushanda nesimba uye tembiricha yeiyo adsorption shongwe;iyo regeneration system yakashongedzerwa ne thermometer, gauge yekumanikidza uye thermocouple kuendesa kure kure tembiricha yekubuda kweiyo heater yekuvandudza, inotonhorera uye yekuvandudza gasi reiyo adsorption shongwe kune yekudzora kamuri;iyo control cabinet ine PLC control instruments.

(5) Yese midziyo yemagetsi pamudziyo inoputika-inodzivirira dhizaini.Iyo pa-saiti inoputika-humbowo nhanho haisi pasi peExd Ⅱ BT4, nhanho yekudzivirira ndeye IP54, uye pa-saiti chiridzwa chekudzivirira chikamu hachisi pasi peIP65.

(6) Manozzles ese ekunze akabatana kune skid.

(7) Iyo adsorption tower yakashongedzerwa yakakosha yekurodha uye yekuburitsa chiteshi che molecular sieve, iri nyore uye nekukurumidza kutsiva mamorekuru.

(8) Pane chivharo chekuchengetedza muhurongwa hwekuvandudza.

(9) Midziyo yakadai seye adsorption tower, yekuvandudza gasi heater, inlet yekuparadzanisa sefa kuvhuvhuta, kugadziridza gasi mvura yekuparadzanisa, tangi yekuunganidza mvura inoputika uye mapaipi avo ekubatanidza achavharirwa.Kana tembiricha yakadzikira kupfuura 5 ℃, iyo blowdown system inogona kutangwa kuchengetedza kupisa uye kutsvaga.

Anti corrosion uye kupisa kuchengetedza kurapwa

(1) Bato B richave nebasa rekupfapfaidza primer uye pendi yekupedzisa pazvikamu zvese kunze kwezvigadzirwa zvesimbi isina tsvina uye zvikamu zvakajairwa.

(2) Bato B richave nebasa rekutenga nekuputira zvinhu zvekudzivirira uye mahwendefa ealuminium eiyo adsorption tower, heater yemagetsi uye pombi.

Mutengi anofanira kupa ruzivo

Air inlet pressure, air inlet flow, air inlet water dow point and gasi outlet water dova point (kana risingawirirane negasi rechisikigo, mukuwedzera, tembiricha yemhepo inopinza uye gasi inogadzirwa. , shale gasi, biogas, gasi, nezvimwewo).
