Production Description
Spray Desulphurization Tower is the main equipment to absorb sulfur dioxide (SO2), including single tower, twin towers, integrated tower and so on. This kind of tower has advantages of high desulphurization efficiency, little resistance, high adaptability and availability. Spray desulphurization tower is dominated tower among the gas desulphurization process.
Types of wet Scrubber Spray Tower
• Single Desulphurization Wet Scrubber
• Main-Vice Desulphurization Wet Scrubber
• Integrated Desulphurization Wet Scrubber
Main-vice Desulphurization Wet Scrubber
Main-vice Desulphurization Wet Scrubber is made of carbon steel and lined with granite. Several modules are separated and assembled at site. (Or made as a whole steel-made tower and lined with granite.) The gas after dedusting enters into the desulphurization tower, and the SO2 containing in the flue gas is purified due to neutralization reaction. The vice tower has the function of dehydration in order to protect the ID fan, flue and chimney that connected after the vice tower.
Installation Statement
| Installation Statement | |
| 1 | After ensuring the position of desulfurization spray tower, infrastructure should be covered normal mortar, the horizontal position should be found after installing the first section according to the number of each section. |
| 2 | Please ensure the consistency between inlet center of the device and the boiler outlet duct center. The connection should be smooth to reduce the resistance of the system. |
| 3 | When hoisting one section, rub the furan resin daub dispatched together with the equipment and then apply furan powder as well as furan resin daub at a ratio of 2.5:1. Then stir and pave them evenly on the annular face of the shell, about 1 to 2 cm thick. When stirring the daub, we shall control the time. |
| 4 | After acid-proof mortar is used to connect sections, joint should be filled with furan resin daub. |
| 5 | Spray pipe, mist eliminator, back washing pipe should have been installed. If somewhere need to be welded, please pay attention to falling sparks to light up mist eliminator. |
| 6 | After the completion of hoisting the whole equipment, daub shall be used to fill full the notch of each section connection and build a slope that is inclined in a downward way so that the rain dew will not accumulate at the seams of the equipment under outdoor environment. |
Preparations before operation
1.Fill full the circulating sink, the limestone slurry pool and soda slurry pool shall be filled adequate water, or high water level will bring about corrosion of circulating water pump), Start the limestone slurry pump and soda slurry pump to ensure the PH value of clean water sink fall between 9 and 12. Control the water level of sink to avoid water being extracted out completely.
2.Check whether the quality of joints between electric motor and water pipe valve is acceptable and water supply system works.
3.Check whether electric motor of stirrer can operate normally and storage of alkaline solution is enough.
4.Check whether sealing device of electric motor is good and shaft is lubricative enough.
5.Check whether outlet baffle of induced fan is open.
6.Check whether outlet of wet scrubber spray desulphurization tower is smooth
7.Open the valves of spray devices.
