Phosgene kukweshainzira yakakosha yekubvisa gasi iri rine njodzi kubva mukuburitswa kwemaindasitiri, kuchengetedza vashandi, nharaunda, uye zvakatipoteredza uku uchiona kutevedzerwa kwemirau yakaoma seiya kubva kuEvironment Protection Agency (EPA).
Pakati pekuita uku ndikokukwesha liquid concentration mita, mudziyo unotarisisa kuwanda kwekukwesha zvinwiwa sesodium hydroxide (NaOH) kuchengetedza kunyura kwakaringana. Nekudzivirira nyaya dzakaita senge under-dilution kana over-dilution, aya metres anowedzera kuita kwegas scrubbing systems.
Lonnmeter, inotungamira uye ine ruzivo mugadziri wehungwaru process sensors, inokunda mukugadzira yakasimba maindasitiri process sensors kuvandudza otomatiki mwero wekubatanidza mutsara wekugadzira. Kunyangwe iwe uriisocyanate mugadziri,mugadziri we polycarbonate, kana kutonga anzvimbo yekugadzirisa tsvina, Lonnmeter inline yekumisikidza mita ndeyekuenda-kune mhinduro yekuvandudza kugona uye kuderedza mutengo.
Kunzwisisa Phosgene Gasi Kukwesha
Kukwesha kunosanganisira kupfuudza phosgene-ine gasi kuburikidza neagasi scrubbing towerkana sisitimu iyo mvura, kazhinji NaOH, inodzikamisa kana kusveta gasi, ichiishandura kuita makomisheni akachengeteka sesodium carbonate (Na₂CO₃) uye sodium chloride (NaCl). Kubudirira kweiyi nzira kunoenderana nekuchengetedza iko kwakaringana kwemvura yekukwesha, iyo iri kupikukwesha liquid concentration mamitakuita basa rinokosha.
Sei Phosgene Gasi Kukwesha kuchidikanwa?
Phosgene gasi kukweshazvinokosha nokuda kwezvikonzero zvakawanda:
Safety:Kuratidzwa kwePhosgene pakudzika kwakadzika se3-5 ppm kunogona kukonzera kutsamwa kwekufema, nepo mazinga epamusoro achitungamira kumapapu edema. Kukwesha kunodzivirira kuratidzwa kwevashandi nenharaunda.
Regulatory Compliance:Mitemo yakasimba, yakadai seiyo inobva kuEPA, inorayira kutarisa uye kudzora kubudiswa kwephosgene kuchengetedza nharaunda.
Environmental Protection:Kusadzora kuburitswa kwephosgene kunogona kusvibisa mweya nemvura, kukuvadza ecosystem.
Operational Continuity:Kukwesha kunoshanda kunodzivirira kutadza kwehurongwa, kuve nechokwadi chekugadzirwa kusingapindiki.
Caustic Scrubbers yePhosgene Gas Scrubbing
Caustic scrubbers anoshandiswa zvakanyanya mukatiphosgene kukweshanekuda kwekureruka kwavo uye kushanda. Vanoshanda nekupfuura phosgene gasi kuburikidza nekoramu yakazara yakazadzwa neNaOH, iyo inomira kuita Na₂CO₃, NaCl, uye mvura. Mafungiro akakosha anosanganisira:
Concentration Monitoring:Iyo NaOH yekumisikidza inofanirwa kuchengetedzwa mukati me5-20 wt% kuti ive nechokwadi chekunwa kunoshanda.
Heat Management:Iyo exothermic reaction inoburitsa kupisa, inoda kutonhora system.
Kuvaka Munyu:Yakakwira NaCl kana Na₂CO₃ mazinga (5-30 wt%) anogona kukonzera crystallization, zvichidikanwa kubviswa kwemunyu kudzivirira kuvharika kwehurongwa.
Redundancy:Mapombi ekuchengetedza uye magetsi ekukurumidzira anovimbisa kuenderera mberi kwekushanda.
Basa Rokukwesha Liquid Concentration Meters
Anoshanda Sei?
Kukwesha liquid concentration mamitakuyera kuwanda kweNaOH, NaCl, uye Na₂CO₃ munguva-chaiyo, kuve nechokwadi chekunyura kwakaringanagas scrubbing systems. Uchishandisa ultrasonic tekinoroji, aya mamita anoongorora sonic velocitymanufactured by Lonnmeterkuziva concentrations.
Iyo mita yekunyudza sensor inowanzo kuisirwa muDN 80 mapaipi pakati pekugezesa uye tangi yekuvandudza, ichibatanidza neyekutonga masisitimu ekugadzirisa otomatiki.
Zvishandiso muPhosgene Scrubbing
Inline Monitoring:Inovimbisa kuenderana kwemvura kuumbwa panguva yekukwesha.
Process Control:Inogadzirisa otomatiki NaOH dosing kana kubviswa munyu kudzivirira crystallization.
Waste Management:Inoongorora zvakasara zvekemikari kuti idzokororwe kana kuraswa.
Zvakanakira Kukwesha Liquid Concentration Measurement
Kuchengetedzwa Kwakawedzerwa
Kukwesha kuyerwa kwemvurainova nechokwadi chekuti mvura yekukwesha inogara ichishanda, ichideredza njodzi yekubuda kwephosgene. Izvi zvakakosha pakuchengetedza vashandi nenharaunda kubva pakusangana negasi rine muchetura uyu.
Regulatory Compliance
Maindasitiri anofanirwa kutevedzera mirau yakasimba, senge iyo kubva kuEPA neOSHA. Concentration metres inopa chaiyo, chaiyo-nguva data yekuburitsa mishumo, kurerutsa maodhisheni uye kudzivirira faindi.
