Ngụkọ dosing RO antiscalant na-atụgharị dose-mmiri nri ahọpụtara n'ime oke mmiri kemịkalụ achọrọ yana ịgbapụta oke mgbapụta dosing. Maka ọgwụ egosipụtara dị ka ngwaahịa azụmaahịa ewepụtara:

  • Oriri ngwaahịa (kg/h) = Nri nri (m³/h) × dose (mg/L) ÷ 1,000

  • Ngosipụta ngwaahịa dị mma (L/h) = oriri ngwaahịa (kg/h) ÷ Njupụta ngwaahịa (kg/L)

Ọ bụrụ na agbazere antiscalant tupu ịgba ọgwụ mgbochi ahụ, mgbako ahụ ga-azakwa maka ọnụ ọgụgụ dị nta nke ngwaahịa enyere na njupụta nke ngwọta ngwaahịa akwadoro.

Mgbakọ ahụ bụ naanị ihe a pụrụ ịdabere na ya dị ka ntinye ya. Usoro akwadoro, ntinye ihe na-arụ ọrụ na-eme ihe na nhazi ngwọta edozi dị iche iche. Ntugharị nkeji ziri ezi na-ekpebi ọnụego nri achọrọ; Ọ naghị egosi ma usoro ahọpụtara ọ dabara maka otu sistemụ osmosis (RO).

1. Kedu ihe nrịba ama na usoro dose ị kwesịrị iji?

Họrọ dose maka ngwa RO akọwapụtara

Nhọrọ antiscalant kwesịrị ịtụle nyocha nri-mmiri, kemịkalụ a na-atụ anya ya, pH, okpomọkụ, mgbake, nhazi akpụkpọ ahụ na ọnọdụ pretreatment. Usoro ahọpụtara kwesịrị ịgbaso nyocha ngwa yana nkwanye maka ngwaahịa na sistemu akpụkpọ ahụ akọwapụtara.

A gaghị ebufe dose a na-eji maka otu nhazi ozugbo na ngwaahịa ọzọ, ọbụlagodi mgbe akọwara ha abụọ dị ka antiscalants RO. Mgbanwe na mgbake nwere ike ịgbanwe kemịkalụ itinye uche, mana ha anaghị enye ọnụọgụ dị mfe maka ịgbakọ ọgwụ kemịkalụ achọrọ. Ịtinyekwu kemịkalụ abụghị ihe ngbanwe maka ịtụle ihe egwu na-egbu egbu na ndakọrịta ngwaahịa.

Tupu ịgbakọ oriri, gosi ka esi akọwapụta mkpokọta akwadoro:

  • Ọnụọgụ ngwaahịa ewepụtara: uka nke ngwaahịa azụmahịa agbakwunyere kwa nkeji olu nke mmiri nri a na-emeso.

  • Usoro ihe na-arụ ọrụ: uka nke akọwapụtara nke ọma na-arụsi ọrụ ike n'otu nkeji oke mmiri nri a na-agwọ.

  • Nleta ihe ngwọta ngwaahịa: Ọnụ ọgụgụ nke ngwaahịa a na-enye n'ime mmiri a kwadebere nke mgbapụta dosing na-ebute.

Ụkpụrụ ndị a anaghị agbanwe agbanwe. Ọ bụrụ na ekwupụtala nkwanye dị ka mg/L nke ngwaahịa ewepụtara, etinyela mmezi ọdịnaya arụ ọrụ.

Ọ bụrụ na onye na-ebubata ya na-akọwapụta ppm karịa mg/L, kwado ntọala ekwuputara. Uru nke dabere na oke ppm na-anọchite anya mg/kg; ịtụgharị ya kpọmkwem na mg/L chọrọ njupụta mmiri dị mkpa. Mgbakọ ndị dị n'isiokwu a na-eji usoro mg/L akọwapụtara nke ọma.

Jiri eruba na ebe a na-enye ọgwụ

Maka otu dose akọwapụtara kwa liter nke mmiri nri RO, jiri usoro nri na-abanye na oke ọgwụgwọ akọwapụtara, kama ịgbapụta mmepụta permeate.

Maka sistemu RO kwụ ọtọ dị mfe:

Iweghachite = Permeate eruba ÷ Nri nri

Dịka ọmụmaatụ, ọ bụrụ na mmepụta permeate bụ 75 m³ / h na mgbake 75%, ntinye nri kwekọrọ bụ:

75 ÷ 0,75 = 100m³/h

Iji 75 m³ / h kama 100 m³ / h na ngụkọ dabere na mmiri nri ga-eleda oke ngwaahịa achọrọ anya site na 25%.

Sistemu nwere iyi mgharịgharị ma ọ bụ ọtụtụ ebe injection chọrọ nlekọta ọzọ. Kọwaa iyi a na-agwọ, chọpụta ebe kemịkalụ dị ọhụrụ na-abanye n'ime sistemu ahụ, wee kọwapụta kemịkalụ ọ bụla na-alọta site na mgharịgharị. Mgbasa mgbasa ozi n'ime adịghị adaba na ntinye nri ọhụrụ chọrọ dose ọhụrụ.

2. Otu esi agbanwe dose Antiscalant site na mg/L ruo kg / h na L / h

Gbakọọ ọsọ ọsọ ngwaahịa achọrọ

Maka ọgwụ egosipụtara dị ka ngwaahịa azụmaahịa ewepụtara:

Ọnụ ọgụgụ nke ngwaahịa (kg/h) = Nri nri (m³/h) × dose (mg/L) ÷ 1,000

Nkewa site na 1,000 na-atụgharị nkeji nke ọma. Otu cubic mita nwere 1,000 lita, ebe otu kilogram nwere 1,000,000 milligrams.

Tụgharịa oke ngwaahịa n'ime oke mgbapụta mgbapụta

Ozugbo amaara oke mmiri achọrọ, gbakọọ olu ngwaahịa dị mma:

Ngosipụta ngwaahịa na-adịghị mma (L/h) = Ọnụ ahịa ngwaahịa (kg/h) ÷ Njupụta ngwaahịa (kg/L)

Njupụta dị mkpa n'ihi na kilogram na lita anaghị agbanwe agbanwe ma ọ bụrụ na amataghị njupụta mmiri. Jiri njupụta dabara na ọkwa ngwaahịa ewepụtara yana ọnọdụ nha dị mkpa.

Ọmụmaatụ rụrụ ọrụ: na-agbakọ eruba antiscalant dị mma

Ụkpụrụ ndị a bụ ntinye mgbako echiche. Ha abụghị nkọwapụta ngwaahịa QINGQUAN ma ọ bụ usoro ọrụ akwadoro.

Were:

  • A na-eche na njupụta ngwaahịa dị ọcha: 1.20 kg/L

Kwụpụ 1: Gbakọọ oriri ngwaahịa

Nzọụkwụ 2: Tụgharịa uka eruba n'ime olu eruba

0,300 ÷ 1.20 = 0.250 l/h

N'okpuru echiche ndị a, ọnụego nri achọrọ bụ 0.300 n'arọ nke ngwaahịa a na-enye kwa elekere, nke ya na 0.250 L / h na njupụta echere.

Mgbakọ a na-egosi ntugharị otu naanị. A ga-ahọrọ dose ahụ iche dabere na kemistri mmiri, ihe ndị chọrọ akpụkpọ ahụ na nkwenye ngwa akọwapụtara nke ngwaahịa.

Ọ bụrụ na akọwara n'ụzọ doro anya dị ka ihe na-arụsi ọrụ ike dị ka ihe na-arụsi ọrụ ike, a ga-edozi oke ngwaahịa a na-eweta maka obere akụkụ na-arụsi ọrụ ike.

Nri nrịbama ngwaahịa (kg/h) = Nri nri (m³/h) × Ọgwụ na-arụ ọrụ (mg/L) ÷ [1,000 × fraction mass na-arụ ọrụ]

A na-akọwapụta ụmụ irighiri ihe na-arụ ọrụ dị ka nkeji iri. Dịka ọmụmaatụ, ọnụọgụ ọnụọgụ ekwenyesiri ike nke 0.10 na-anọchite anya 10% site na oke.

Tinye mmezi a naanị mgbe nkwanye dose ahụ na-ezo aka na ihe ahụ na-arụ ọrụ achọpụtara na akwụkwọ ngwaahịa na-akọwa ntọala ntinye dị mkpa. Njupụta, pH ma ọ bụ nkọwa dị ka “gbadoro anya” enweghị ike dochie ozi ọdịnaya na-efu efu.

3. Otu esi agbakọ usoro ịgbakọ dosing-pump maka ngwọta ngwaahịa agbazere

Kọwaa mkpokọta ngwaahịa nke ọma

Ngwọta ngwaahịa nwere 10% w/w ngwaahịa ewepụtara nwere kilogram 10 nke ngwaahịa azụmaahịa n'ime kilogram 100 nke ngwọta emechara. Nke a apụtaghị na 10% nke olu ngwọta bụ ngwaahịa azụmahịa, ma ọ bụ na ọ pụtaghị na ngwaahịa ahụ nwere 10% na-arụ ọrụ.

Maka ngwọta ngwaahịa dabere na oke, kọwaa:

  • wp: eweta-ngwaahịa uka nta n'ime njikere ngwọta.

  • ρs: njupụta nke ngwọta ngwaahịa a kwadebere, na kg/L.

  • qs: ihe ngwọta ngwaahịa achọrọ, na L/h.

  • mp: a chọrọ ka ewebata-ngwaahịa oke eruba, na kg/h.

Nha nhata nke ngwaahịa bụ:

Ngwunye ihe ngwọta ngwaahịa (L/h) = Ọnụ ọgụgụ nke ngwaahịa (kg/h) ÷ [Mkpụrụ nrịbama ngwaahịa × Njupụta ngwaahịa (kg/L)]

Mpekere oke ngwaahịa na njupụta ngwaahịa ga-arụtụ aka na otu ngwọta akwadoro. Ejila njupụta nke ngwaahịa dị ọcha dochie njupụta nke ngwaahịa ahụ ozugbo maka njupụta nke ngwaahịa agbazere.

A olu dabeere dilution uzommeputa chọrọ ya n'ụzọ doro anya kọwaa ngụkọta oge ndabere. A gaghị emeso nkwupụta dịka "10% w/w" dị ka 10 lita ngwaahịa agwakọta na 90 lita mmiri.

Ọmụmaatụ rụrụ ọrụ: ịgbakọ ọsọ ngwaahịa agbazere

Gaa n'ihu na echiche echiche achọrọ nke 0.300 kg / h nke ngwaahịa ewepụtara.

Were:

  • Ngwa ngwa ngwa ngwa ewepụtara achọrọ: 0.300 kg / h

  • Iberibe oke ngwaahịa ewepụtara na ngwaahịa: 0.10

  • Njupụta ngwọta ngwaahịa akwadoro: 1.02 kg/L

Usoro ihe ngwọta ngwaahịa achọrọ bụ:

0.300 ÷ (0.10 × 1.02) = ihe dịka 2.94 l / h

Ọnụnọ nke oke ngwaahịa dị ihe dịka:

2.94 × 1.02 = 3.00 n'arọ / h

N'ihe dị nta nke ngwaahịa 0.10 ewepụtara, ihe ngwọta a na-ebuga ihe dịka 0.300 kg / h nke ngwaahịa ewepụtara. Dilution na-abawanye olu nke mgbapụta ahụ na-enye, mana ọ naghị agbanwe oke ngwaahịa a chọrọ.

Naanị ịmụba olu ngwaahịa dị mma site na iri ga-eleghara ọdịiche dị n'etiti njupụta ngwaahịa dị ọcha na njupụta ngwọta ngwaahịa.

Maka nrụnye n'ezie, soro ọnọdụ nkwadebe na dilution enyere maka nhazi ahụ akọwapụtara. Ogo dilution-mmiri, ọnọdụ nchekwa na nkwụsi ike ngwaahịa kwesịrị ka enyocha ya megide akwụkwọ ngwaahịa dị. Ngwaahịa 10% nke a na-eche n'echiche a na-eji ebe a bụ ihe atụ mgbako, ọ bụghị ntụziaka nkwadebe zuru ụwa ọnụ.

4. Kedu RO Antiscalant Product Data ga-ekwenyerịrị?
