Abstract
The characteristic lies in that the crushed bauxite is put in the reaction still to react with hydrochloric acid or sulfuric acid. The recation temp. is 80-100 deg.C, the reaction pressure is 3-5 atmospheric pressure. Then the reacted mixture is poured in the stirred pool and the high aluminium lime and water are added in at temp. of 60-75 deg.C, then they are stirred for 2-5 hr, and it is obtained after precipitation. The water purifier of poly aluminium-ferrous chloride and polymerized aluminium-ferrous sulfate produced by said method features good result for purifying water, simple productive process, quick speed for purifying water and non corrosiveness.
Description
The present invention belongs to the natural terrain water of field of environment protection to purify the water purification agent of handling usefulness with industry, civil sewage.
The at present domestic water purification agent of generally producing mostly is single aluminium salt and single molysite greatly, for example Tai-Ace S 150, aluminium chlorohydroxide, polymerize aluminum chloride, iron trichloride, ferrous sulfate, bodied ferric sulfate etc., the shortcoming of its product mainly is the production cost height, cleaning water is low, water purification speed is slow: great majority have the different corrodibility of degree.
The object of the invention provides that production cost is low, cleaning water is high, the fireballing water purification agent of water purification.
The present invention is achieved in that
The technology of poly aluminium chloride iron is: bauxite → pulverizing → hydrochloric acid acid is molten → and alkaline substance polymerization → precipitation → separation → product
Bauxite is through pulverizing, in reactor with hydrochloric acid at temperature 80-100 ℃, pressure is under 3-5 the normal atmosphere, after reaction in 2-5 hour, pour in the agitated pool, add water and stir, when heating, add the high alumina ash to 60-75 ℃, the reaction times is 1.5-4 hour precipitation, separate product.
Proportioning raw materials is:
Bauxite 12-18%, high alumina ash 8-10%
Hydrochloric acid (concentration is 30%) 35-42%, water 30-45%
The production technique of PAFS:
Bauxite → pulverizing → sulfuric acid solution → modification → precipitation → product (chemical formula [(AL

Proportioning raw materials is:
Bauxite 14-18, sulfuric acid (concentration 90%) 20-35%, high alumina ash 0.25-0.5%, water 46.5-65.7%.
Poly aluminium chloride iron of the present invention, the PAFS cost is low, and purifying water effect is good, and cohesive force is strong in water purification, and sedimentation speed is fast, and filterableness is good, has no side effect, and is easy to use, simple to operate, and can not increase corrosion to equipment, pipeline.
The poly aluminium chloride iron (20 ° of B é) of producing 1 ton is after 150kg bauxite is pulverized, join in the reactor, with 30% hydrochloric acid of 390kg be through 2 little reactions under 4 normal atmosphere at 95 ℃ of temperature, pressure, then mixture is put into agitated pool, in temperature is under 75 ℃, add 90kg high alumina ash and 470kg water, stirred 2 hours, post precipitation gets product.
Producing 1 ton of PAFS is after the bauxite of 160kg is pulverized, join in the reactor, with 90 sulfuric acid of 300kg be that 100 ℃, pressure are just then the mixture in the reactor to be put into agitated pool through 2.5 hours anti-under 4 normal atmosphere in temperature, in temperature is under 70 ℃, add 4kg high alumina ash and 636kg water, stirred 2 hours, the precipitation and product.
