The methods of quick lime exothermic mixture heats.When wherein using quick lime and the organic contamination sludge agitation containing organic pollution, raw stone
Ash and combination reaction heat caused by the moisture in the organic contamination sludge of organic pollutants, directly with containing the organic of organic pollution
Sludge contact is heated and makes the method for the moisture evaporation in organic contamination sludge, is at a kind of organic pollutants and organic contamination sludge
Manage lower-cost method.
Drying and other treatment is carried out to organic pollutants and organic contamination sludge using the reaction heat of quick lime exothermic mixture and water, is not required to
Heat energy is given from outside, simultaneously as the reaction organic contamination sludge of quick lime heating is converted into meta-alkalescence, oxygen by slant acidity
During change calcium changes into calcium hydroxide with water, calcium oxide is to the volatile organic component and heavy metal in organic contamination sludge
Trace element etc. generates the effect such as ion exchange and crystallisation solidification so that the foul smell in organic contamination sludge is eliminated.
Prior art has the method and equipment to organic contamination sludge drying using high-temperature steam, and its original intention is to make up quick lime hair
The deficiency of the method for thermit powder, reduce the loss of calorific value.But due to containing in waste gas caused by quick lime and water with substantial amounts of powder
Trifle in the world matter, constantly block in the secondary use of waste heat heater be allowed to can not normal operation, utilize various filters to remove
Waste heat is also reduced to normal temperature simultaneously after dust impurities, therefore, the technical method lose the reality of its use value, big
Confirmed in amount engineering practice.
