Price Description:
Detailed Product Description：	This product is our patent product for 1 - 130T coal-fired boiler, oil boiler, heat and power plant fluidized bed boiler, the smelter furnace desulphurization and dust removal. First, the works The XL-D multi-stage high efficiency desulphurization and dust removal desulfurization Our company (factory) combined with years of desulfurization equipment operation practices, problems exist for the wet FGD to improve the desulfurization efficiency design and development of next-generation products. The product is maintained at the same time carbon steel + clay scales corrosion or reinforced concrete + clay flake anti-corrosion materials, acid, alkali, wear advantages, but also has the following significant features: A flue gas desulphurization by washing multi-stage separation dehydration. Undertaking a unique design of the rotary washing device, set in the multi-stage separator for exhaust movement of imports under the above exhaust gas from the bottom of the imports into the scrubber liquid is generated by the decomposition of water droplets, mist mixed in the gas rise This process is to increase the degree of dust body weight adhesion, and full access to and sulfur dioxide gas and the alkaline washing liquid. 2 cylinder body, within legislation cylindrical, the upper part of the unique design of the rotating multi-chip inertial separation devices not only separately, but also closely linked to the structure. Not only makes the combination of detached droplets in the gas liquid fluid in a round basin, once again dispersed, rotating airflow with conversion into a multi-port rotary separator. Both the gas dispersion liquid of various joint diversion board, but also play the role of the secondary liquid droplets dispersed in the gas. The desulfurization efficiency ≥ 80%, in order to ensure continuous reliable operation of the HSS devices. By the combination of the inner cylinder into the workspace outsourcing his mouth round dehydration tube, into the lower part of the work area by Dr Di, the water vapor mixing up several times in centrifugal gas-liquid separator, droplet again produce mixed, after the separation containing small portion of droplets of the gas into the space of dehydration, a more reliable separation from the bottom up low flow rate centrifugal dehydration. Achieve the moisture content of the gas emissions <8 the best available data. All the materials used in the tower in vitro and in vivo compared with the five leakage of alkaline white phenomenon of granite materials. So, the tower body is beautiful, sturdy, corrosion, wear, and no air leakage leakage. Second, the technical indicators and parameters SO2 emission concentration: ≤ 400mg/Nm3, (to meet the water pressure, water quality and amount of drugs); (2) the concentration of dust emissions: ≤ 120mg/Nm3 (now in the flue gas report data); The device resistance: ≤ 1200 Pa,; Flue gas moisture content: ≤ 8; Liquid-gas ratio: ≤ 0.8 l/m3; (6) the utilization of recycled water ≥ 95%; Desulfurization process is safe, reliable, high technology, the system is simple, short duration, low investment and operating costs; Device main side of the device can run side repair; 9 does not affect the boiler combustion conditions; 10 device master life: ≥ 20 years; 11 after the construction of an integrated system of the desulfurization equipment, in order to optimize the process to achieve maximum social and economic benefits. Third, the technical standards and regulations "Design of Industrial Enterprises hygiene standards (GB17055-1997) "Construction for fire protection design (GBJ16-87) (3) industrial and civil general equipment of electrical installations design specifications (GBJ55-83) Four. "Seismic Design of Buildings" (1993 partial revision GBJ11-89) Five. "Design of Concrete Structures" (1993 partial revision GBJ11-89) 6. "Steel design specifications (GBJ17-88) 7 building structures specification "(GBJ9-87) 8 design of building foundation specification (GBJ7-89) Fourth, the design principles Select the proven desulfurization and dust removal process; (2) to minimize the investment in desulphurization and dust removal systems engineering; (3) process indicators to meet the desulphurization and dust removal system under the premise of best corporate energy saving; Desulphurization and dust removal system to maintain, easy management. Fifth, the basic principle of "dual-alkali absorption The basic chemistry principles can be divided into the desulfurization process and the regeneration process: Ⅰ. Desulfurization process: Sodium-calcium pairs of alkali Na2CO3-Ca (OH) 2] method using sodium alkali start to absorb SO2, lime regeneration. Compared with limestone France and other desulfurization process has the following advantages: Na2CO3 + SO2 ← → Na2SO3, + CO2 ↑ (1) 2NaOH + SO2 ← → Na2SO3, + H2O (2) Na2SO3 + SO2 + H2O ← → 2NaHSO3 (3) The above three type as the absorption of the solution pH varies: (1) absorption to start the reaction; (2) for the reaction (water pH 9); alkaline reduce to neutral or even acidic 5
