Akụkụ Electrolysis: eriri electrolyzer

a. Sistemụ Anolite

A na-enyefe brine dị ọcha nke ukwuu site na tank brine dị ọcha site na nke ọ bụla n'ụdị electrolyzer wee kesaa ya n'ọnụ ụlọ anode ọ bụla ebe ọ na-aghọ chlorine na ion sodium. Onye na-ahụ maka eruba nke nwere pipeline brine nri na sekit eletrọlịza ọ bụla na-enyocha ọnụọgụ brine dị ọcha nke ukwuu.

Mmiri mmiri nke nwere akụkụ abụọ nke brine mebiri emebi na gas chlorine dị mmiri na-asọfe site na ọnụ ụlọ anode ọ bụla n'ime ebe a na-anakọta nke nwere electrolyzer nke ọ bụla nke na-ekewapụ brine na chlorine.

Nri ahụ mebiri emebi sitere na manifold na-esi na ọkpọkọ alaka na isi isi banye na tank anolyte site na ike ndọda, ebe a na-eziga gas chlorine na B/L (ngalaba nhazi gas chlorine).

A na-ebufe brine nke si na tank anolyte na mpaghara dechlorination site na njikwa ọkwa. A na-emegharị ụfọdụ brine mebiri emebi n'ime tankị anolyte na ndị electrolyzers site na ịgwakọta ya na brine dị ọcha dị ọhụrụ.

A na-enye eriri mmiri nke demineralized maka dilution anolyte iji gbochie crystallization nnu n'oge mmechi yana maka mmezi ntinye uche nke anolyte iji zute ihe akpụkpọ ahụ chọrọ n'oge mmalite.

b. Sistemụ Catholyte

A na-enyefe caustic nke ọ bụla na electrolyzer manifold site na onye na-ekpo ọkụ catholyte, wee kesaa ya na ụlọ cathode ọ bụla ebe mmeghachi omume cathode na-emebi mmiri n'ime hydrogen na ions hydroxide. Onye na-ahụ maka mmiri na-asọ asọ nke etinyere na sekit electrolyzer ọ bụla na-achịkwa ọnụego nrụgharị caustic.

Mmiri nke ụzọ abụọ nke ihe ngwọta caustic na hydrogen gas na-esi n'ime ụlọ cathode ọ bụla na-asọba n'ime ebe nchịkọta nke a kwadebere na electrolyzer ọ bụla bụ ebe a na-ekewa ihe ngwọta caustic na hydrogen.

Ihe ngwọta nke caustic sitere na manifold na-agafe na ọkpọkọ alaka, na isi isi n'ime tankị catholyte site na ike ndọda, ebe a na-eziga hydrogen gas na ngalaba nhazi gas hydrogen site na alaka na nkụnye eji isi mee. Mgbe ị na-ahapụ tankị nke na-emegharị ihe, ihe ngwọta caustic na-ekewa n'ime iyi abụọ: iyi ngwaahịa na B / L na iyigharị caustic iyi na electrolyzers.

Onye na-ekpo ọkụ soda na-ekpo ọkụ na-ekpo ọkụ ma ọ bụ na-eme ka caustic megharịa ka ọ nọgide na-arụ ọrụ okpomọkụ na 85 ~ 90 deg-C. N'oge mmalite, a na-eji ihe na-ekpo ọkụ soda na-ekpo ọkụ na-ekpo ọkụ na-ekpo ọkụ na electrolyte, na-eme ka njedebe zuru oke dị ugbu a na-enweghị oke voltaji.

A na-enyocha ike caustic electrolyzer site na njiri njupụta nke caustic, ma na-edobe ya na ihe dịka 32wt%, mkpokọta arụmọrụ kachasị mma nke akpụkpọ ahụ, site na ịchịkwa ọnụọgụ mmiri na-emebi emebi n'ime iyi caustic megharịrị.

Iji chọpụta ihe na-adịghị mma nke electrolyzers, a na-etinye voltaji electrolyzer na usoro nlekota okpomọkụ.

c. Sistemụ gas

A na-achịkwa nrụgide hydrogen gas na ihe ruru. 400 mm H2O dị elu karịa nrụgide gas chlorine.
