water film desulfurization deduster

Dust PrinciplesBoiler flue gas in the role of induced draft fan, by the tangential gas imports into the filter and along the inner wall of high-speed rotation rise; upper part of the overflow tube device, it can form a layer of 3-5mm wall perfectly uniform water film; smoke gas rises with the water film reverse contacts, the role of dust particles due to centrifugal force, trajectory changes left out of the cylinder wall, most of them were water film capture; dust at the bottom of the post by the overflow of sewage discharged into the circulating pool of mouth precipitation and then used; clean flue gas from the chimneys into the atmosphere. (In the loop to join the pool configured lye, you can play a desulfurization effects)

Desulfurization PrincipleUse of dual-alkali (NaOH and Ca (OH) 2) desulfurization, the law is to start using NaOH as desulfurization agent, desulfurization products were reduced to NaOH and beat back the use of desulfurization tower. The desulfurization system in the dust catcher house, right behind the device had no effect. The chemical reactions carried out as follows:The main reaction: NaOH + SO2 → Na2SO3 + H2OSide effects: Na2SO3 + SO2 + H2O → NaHSO3NaOH Regeneration: Ca (OH) 2 + Na2SO3 → 2NaOH + CaSO3Desulfurization specific operations1, run box before adding lye 96% ~ 99% of caustic soda and water to fully dissolve in order to do backup.2, in the mixing tube have added lime powder and water mixing into a stone mortar to make backup.3, run the pool circulation before adding 96% ~ 99% of caustic soda or caustic soda, so that PH value reached 98, and this time the system will enter the desulfurization operation status.4, operation and pay attention to circulating pool PH value of the solution changes in less than 9 below, start the liquid caustic soda lye box and add a small amount of mixing tube inside the stone mortar, the two slowly circle into the pool, so that PH value to operational requirements. Note that circular pool of water to replenish.5, the solution of general circulation in the pool half cycles.Specifications1, dust removal efficiency: ≥ 95%2, desulfurization efficiency: ≥ 80%3, import tobacco-speed :18-22m / s4, up smoke-speed :4-5m / s5, emission concentration <200mg/m36, device resistance: ≤ 800Pa7, Ringelmann smoke blackness 0-1 grade

Features1, the equipment used in all body-site natural granite masonry, because of the special nature of material, it has strength, high temperature, corrosion resistance and so on.2, the whole long life, stable performance, operation is also simple, easy operation and maintenance.
