by a hydraulic pressure butterfly valve of opening in a lime white centrifugal dehumidifier, wait a lime Slurry centrifugal dehumidifier fills a number hydraulic pressure butterfly valve of closing after slaked lime slurry, then opens No. two hydraulic pressure butterfly valves, anti-from quick lime The slaked lime slurry that the funnel in bottom portion comes out is answered to enter No. two by No. two hydraulic pressure butterfly valves of opening after lime slurry pump pressurizes In lime white centrifugal dehumidifier.Start a lime white centrifugal dehumidifier, calcium hydroxide is slightly soluble in water, from a lime white The calcium chloride solution containing micro calcium hydroxide that centrifugal dehumidifier comes out enters neutralization reaction kettle after neutralizing pump pressurization In.Dehydration terminates a number lime white centrifugal dehumidifier for the first time, a lime white centrifugal dehumidifier shuts down, and starts pure Clarified water pump, pure water pump extracts pure water from purifying water pool and flows into a lime white by a pure water solenoid valve of opening The slaked lime slurry in a lime white centrifugal dehumidifier after the dehydration of the first magnetic is soaked in centrifugal dehumidifier, then starts one Number lime white centrifugal dehumidifier 4 carries out second to slaked lime slurry and is dehydrated.By twice dehydration white lime mud from a stone Released in mortar centrifugal dehumidifier, be that the charging of next round slaked lime slurry is prepared.Deng No. two lime white centrifugal dehumidifier dresses No. two hydraulic pressure butterfly valves are closed after full slaked lime slurry, a hydraulic pressure butterfly valve is then opened, goes out from the funnel of quick lime reactor bottom The slaked lime slurry come enters a lime white centrifugal dehydration by a hydraulic pressure butterfly valve of opening after lime slurry pump pressurizes and filled Put in 4.Start No. two lime white centrifugal dehumidifiers, contain micro hydroxide from what No. two lime white centrifugal dehumidifiers came out The calcium chloride solution of calcium enters in neutralization reaction kettle after neutralizing pump pressurization.No. two lime white centrifugal dehumidifiers are de- for the first time Water terminates, No. two lime white centrifugal dehumidifiers shut down, and pure water pump extracts pure water from purifying water pool and passes through opening No. two pure water electromagnetism flow into No. two lime white centrifugal dehumidifiers in immersion for the first time be dehydrated after No. two lime whites centrifugation Slaked lime slurry in dehydration device, then starts No. two lime white centrifugal dehumidifiers, to No. two lime white centrifugal dehumidifiers Slaked lime slurry carry out second and be dehydrated.The white lime mud Jing Guo twice dehydration from No. two lime white centrifugal dehumidifiers White lime mud is released, and is that the charging of next round slaked lime slurry is prepared.A number lime white centrifugal dehumidifier and No. two lime whites from Heart dehydration device is dehydrated to the slaked lime slurry come out from quick lime reactor in turn.From a lime white centrifugal dehumidifier It is good construction material, white lime with the white lime mud containing calcium chloride released in No. two lime white centrifugal dehumidifiers In have no effect on the quality of white lime containing a small amount of calcium chloride, calcium chloride is the main additive of cement, is a kind of water reducer, White lime, cement, sand are mixed in proportion with water and mud, then cover brick wall wall indoors and mixed with the mud become reconciled On solidifying soil ceiling.Chlorine burns in hydrogen in burner generates hydrogen chloride gas and discharges substantial amounts of heat, in combustion The hydrogen chloride gas produced in burner, which enters to be dissolved in neutralization reaction kettle in calcium chloride solution, turns into hydrochloric acid, the chlorination in hydrochloric acid Hydrogen occurs chemical reaction generation calcium chloride and water with the calcium hydroxide in calcium chloride solution, concurrently bears substantial amounts of heat.Or Hydrochloric acid pump extracts concentrated hydrochloric acid from hydrochloric acid tank, during the concentrated hydrochloric acid pumped out from hydrochloric acid enters neutralization reaction kettle, the chlorination in hydrochloric acid Hydrogen occurs chemical reaction generation calcium chloride and water with the calcium hydroxide in calcium chloride solution, concurrently bears substantial amounts of heat.Neutralize It can accelerate the hydrogen chloride and chlorine in neutralization reaction kettle equipped with the neutralization agitator work being equipped with neutralization agitator on reactor The calcium hydroxide changed in calcium solution chemically reacts.From the temperature that comes out of reactor very high calcium chloride solution is neutralized by spray Enter the number row of first order sprayer after the first order flash distillation liquid feeding pump pressurization of mist formula calcium chloride solution multistage flash evaporation enrichment facility In the calcium chloride
