4t boiler desulfurization with caustic soda

Hongyu Caustic Caustic 4t boiler desulfurization Contact: Toshihide 13931721530 90 90 Industrial Caustic Caustic Caustic is non-GB is mainly used for sewage treatment, boiler cleaning, brick desulfurization using caustic soda national standards Caustic is GB209-2006 industrial wastewater treatment from 90 to 32% of the caustic lye into the section of the tank, pump lye into the EV - 1, heating under vacuum concentration rose from 32% 48%. After evaporation concentrated by heating pump from EV - extract 1 through the heat exchanger HE - 2 and HE - 3 arrival EV - 2, after EV - 2 alkali concentration raised to 56%, then pump the lye from EV - 2 into the EV - 3. In order to prevent corrosion of equipment NaClO 3, lye entering EV - to add a certain amount of 5% sugar solution before 3. After EV - 3 56% lye dehydration, to achieve high concentrations of molten alkali. High concentrations of molten alkali rely canister by gravity into a producer of caustic soda to cool, caustic soda caustic soda into the groove to the packing scale packaging, leave out from packing scale interface alkali dust being sucked dust Caustic national standards (GB209 -2006) on solid sodium hydroxide (including flaky, massive, granular) part of the standard: 99 caustic soda (IS-IT-Ⅰ) sodium hydroxide, sodium carbonate ≥ ≤ ≤ sodium ferric oxide ≤ superior product First grade 0.5 99.0 98.5 0.8 0.03 0.005 0.008 0.05 0.08 0.01 1.0 98.0 qualified for caustic soda 96 (IS-DT-Ⅰ) sodium hydroxide, sodium carbonate ≥ ≤ ≤ sodium ferric oxide ≤ superior products 96.0 1.2 2.5 0.008 a and other goods 96.0 95.0 1.3 2.7 0.01 1.6 3.0 0.02 Qualified NOTE IS: solid sodium hydroxide caustic soda is a basic chemical raw material, widely used in papermaking, synthetic detergent and soap, viscose fiber, rayon and cotton fabrics and other textile industries , pesticides, dyes, rubber and chemical industries, oil drilling, refining petroleum grease and tar oil refining industry and the defense industry, machinery industry, wood processing, metallurgical industry, pharmaceutical industry and urban construction and other aspects. Also used in the manufacture of chemicals, paper, soap and detergent, artificial silk and cellophane, processing bauxite alumina, aluminum is also used silk textiles at the water treatment. Caustic generally use three 25kg plastic woven bag, inner and outer layers of plastic bags, the middle layer of plastic bags endometrial. Caustic soda was "common classification of dangerous chemicals and signs (GB 13690-92)" classified as Class 8.2 alkaline corrosive substances, is eight dangerous goods IMDG Code: 1823. It should be stored in ventilated and dry goods warehouse or shed. To complete the packaging container and sealed. Shall not combustible and acids during storage or shipment. During transport to avoid moisture and rain. Fire, water, sand and a variety of fire extinguishers to fight the blaze, but firefighters should be noted that corrosive caustic soda dissolved in water after. Production of alumina, zinc and copper surface treatment and glass, porcelain pond, leather, pharmaceuticals, dyes and pesticides used. It can be used for citrus, peaches and the like peeling agents and bleaching agents, deodorant. Widely used in various sectors such as chemicals, paper, printing and dyeing, electricity and so on. After the first predetermined temperature by heating equipment within caustic soda (430 degrees) ceasefire, after toning, settlement, so that the color had to caustic requirements, liquid caustic soda into the mechanism of the finished base sheet, after forming into the drum, cooler cooling, cooling after packaging into the warehouse. This is just a simple schematic. Available!
