After a long time of joint exploration and development,YANCHUANG SCIENCE AND TECHNOLOGY CO., LTD. and design institutes and cooperative colleges have made significant breakthroughs and Optimization in wet,dry and semi-dry flue gas desulfurization technology.The most reasonable scheme has been worked out by investigating and analyzing the actual situation of different users.It solves the problem for users and gains the trust of users.
Aiming at users of steel making,heating and environmental protection,YANCHUANG TECHNOLOGIES CO., LTD. has innovated on the basis of traditional double subtraction desulfurization technology,independently developed several technical patents,which have achieved remarkable results in flow field distribution, flue gas mixing,desulfurization efficiency,fog removal and dust reduction.At the same time,under the premise of technological innovation,the investment cost and operation cost have been reduced,and thus won the praise of customers.
Highlights of the new technology :
1. New technology of flow field equalization in built-in pipeline of desulfurizationtower
2. Solid spray technology and agglomeration atomization technology
3. Swirl Disturbance and Surge Mass Transfer Technology for Special Airfoils
4. Automatic cleaning of baffle interception defogging and gas-water separation
technology
5. New process layout desulfurizer regeneration technology
Sodium-calcium double-alkali desulfurization process is similar to other wet desulfurization processes such as limestone-gypsum process.The main reaction is that SO2 in flue gas is dissolved in absorption solution and then dissociated into:
H+ ,HSO3 SO2(g) = SO2(aq)(1)
SO2(aq)+H2O(l) = = H++HSO3 = 2H++SO32-(2)
Formula (1) is a slow reaction,which is one of the speed control processes.
Then H + reacts with OH - in solution to form salt and water,which promotes the continuous absorption and dissolution of SO2.
The main reaction equations are as follows:
Absorption process:Na2CO3 + SO2 → Na2SO3 + CO2↑
2NaOH + SO2 → Na2SO3 + H2O
Na2SO3 + SO2 + H2O → 2NaHSO3
Regeneration process2NaHSO3 + Ca(OH)2 → Na2SO3 + CaSO3↓+ 2H2O
Na2SO3 + Ca(OH)2 → 2NaOH + CaSO3↓
Oxidation process:Ca(OH)2 + Na2SO3 + 1/2O2 + 2H2O → 2NaOH + CaSO4H2O
Negative products under desulfurization precipitate in the form of CaSO3and CaSO4,and then they are beaten to ash water drainage treatment system by slurry pump and disposed of harmlessly directly for sale.
Technical advantages:
1. Customization scheme provides optimal design for users
2. Small area and rational use of site resources
3. Low cost of equipment investment
