Production Description

Single 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.) Inside devices include three-level spray systems, two-level baffle demisters and three-level backwash spray equipments. The efficiency to get rid of SO2 can be up to 90%.

Large-scale Tower and Accessories (flue gas treatment ＞ 100000m3/h)

Installation Materials

1.Acid-proof mortar (yellow) ,glassy water(transparent liquid), furan powder(black), furan resin (black liquid), the above installation accessories will all be delivered from my company together with equipment.

2.Acid-proof cement: 25kg/bag, equipped with 1kg curing agent, mixing evenly after opening.

Inside Details of Desulphurization Wet Scrubber

These are the spray Pipes inside the wet gas scrubber desulphurization tower, which are the main parts that have the function on desulphurization to get ride of SO2. The material of the spray pipe is fiberglass which is 100% corrosion resistant. 

Corrosion prevention is the key of the desulfurization tower, with outer lining steel plate, inter lining granite, and middle acid-resistant castable; called heavy anti-corrosion structure (or flake resin instead)

Principle of Operation

Desulphurization spray layer is based on the upper part of the tower, the absorption tower slurry circulating pump corresponding to each spray layer. The nozzle configuration of spray layer is simulated designed by professional software in order to ensure good contact with alkali and acid reverse gas reaction; and finally reach purification effects.

Demister installs in the upper desulphurization tower, a total of two levels. The net is used to separate the entrainment of flue gas cloud droplets, and droplet concentration in flue gas export from mist eliminator is less than 75 mg/Nm3 (dry basis). At the same time, the equipment also has spray washing device to the tiny dust particles adhesion and desulphurization of flue gas crystallization on the demister system resistance increases.

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.

Transportation

Usually, the wet gas scrubber is transported seperately to make it convenient for long distance transportation. 

Maintenance in Operation

Maintenance in Operation
1	Import pipeline	Import pipeline must be full of liquid; long-term work under cavitations condition of pump is not allowed.
2	Regular Check	Check regularly the current value of electric motor that cannot exceed the rated current.
3	long Running	During long running, if the leakage increases, pressure drops dramatically, or the noise and vibration rise, stop the pump and check. Chang the wearing parts like mechanical seal, bearing, impeller, etc.
