I Cooling Tower Winterizing: Freeze laka invenna atana kaihhruaina pawimawh tak

Thlasik a hnaih tawh avangin khaw lum hmuna facility manager-te chuan harsatna lian tak an tawk a, chu chu an industrial cooling system-te chu khaw lum lutuk laka venhim a ni. Tui hi a vawt chuan a zau a, chu chuan pipe a puak thei a, heat exchanger coil a ti chhe thei a, pump a chhe thei bawk-chu chuan siamthatna man to tak leh downtime rei tak a thlen thei a ni.

 

Tan khar-circuit cooling tower te a awm,freeze chhiatna ven hi maintenance chauh a ni lo va; sumdawnna chhunzawm zel chungchang a ni. I cooling tower winterize theihna tur strategy tha ber berte chu hetiang hi a ni.

 

 

1. Glycol Dosing (A hman dan rintlak ber) .

 

Circulating fluid-ah glycol (a tlangpuiin propylene emaw ethylene glycol) dah chuan a freezing point a tihhniam a ni. Hei hi closed-circuit system tan chuan standard solution a ni a, a chhan chu process fluid hi boruak atanga isolated a nih vang a ni.

 

 

 

 

Thurawn chu:Glycol concentration chu ambient temperature beisei hniam ber aia 10℃F (-12℃) aia hniam lo laka invenna tur khawpa vawn reng tur a ni.

Testing neih dan:Glycol concentration chu refractometer hmangin test fo la, leak emaw tui make-up vangin level a tlahniam lo tih enfiah thin ang che.

 

2. Electric hmanga Heater & Basin Heater te hman theih a ni

 

Pawn lam spray water system (thlipui laka inhawng) tan chuan glycol hi hman a ni lo fo thin. Chu ai chuan tui lum-tui tlakna hmunah electric heater dah a ni.

 

 

 

 

 

 

Thiltih:Heng heater te hi tui lumna freezing hnaih taka a tlak chuan automatic in an activate a, basin tui chu a fluid reng avangin spray pump te chu a thawk thei a ni.

Hmawr:Heater capacity chu i basin volume leh local insulation condition angin size dik tak a nih ngei ngei tur a ni.

 

3. A hun laia Operation & Drain Down

 

Thlasik laiin cooling tower hi 24/7 kal a ngai lo a nih chuan:

Drain Down-ah chuan:System chu hun rei tak chhung idle a nih chuan basin leh piping zawng zawng chu drain vek rawh. Spray nozzle leh coil atanga tui awm chhunte chu compressed air hmangin puak chhuak rawh.

Run inkara tlan: 1.1.Load-in a phal chuan tui a kal zel theih nan system chu a chang chuan run la, mahse off-cycle-ah basin heater-te chu active a nih ngei ngei tur a ni.

 

4. Insulation leh Thlipui Damna

 

Thli lum hian heat loss rate leh freezing risk nasa takin a tisang thei a ni.

Tower casing chhehvelah insulated panel dah rawh.

Air intake louver-a thlipui (wind barrier) hmangin tower chhunga boruak vawt lut zat tihtlem a, chutih rualin hnathawhna atana boruak mamawh chu a la phalsak tho.

 

 

 

Tawpna

 

Freeze protection ngaihtuah turin vur tla hmasa ber nghak suh. I heating elements te enfiah a, i glycol level test te, tunah hian i control logic check te hian a hnua hmanrua thlak nan dollar sang tam tak a humhim thei a ni.

I model bik atana glycol concentration emaw heater size dik tak thlan dan tur thurawn i mamawh em? Vawiin hian kan engineering team te hi biak theih reng e.
