Production Description
Integrated Desulphurization Wet Scrubber is made of carbon steel and lined with flake resin (or granite). The tower can be manufactured in the factory and transport as a whole if the diameter of the equipment is below 5.5m; while the diameter of the equipment is above 5.5m, the tower should be manufactured at site. The integrated desulphurization wet scrubber has the advantages of lightweight and short period.
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.
Transportation
Inside Details of Desulphurization Wet Scrubber
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)
Demister in large tower is made of GRPP, which can bear 130 ℃ flue gas and high speed flow washout. Modular demister is convenient for installation and replacement.
Spray layer includes mother pipe and branch pipe, branch pipes arrange in pairs, which is made of FRP (or 316L stainless steel) with silicon carbide hollow-cone type nozzle (or 316L spiral nozzle). The spray tower commonly deals with huge amount of flue gas; eg. Power station boiler and Steel sintering machine.
Small tower uses steel plate with outer lining steel plate, inter lining granite, and middle acid-resistant castable. Spray device use material of FRP or 316L stainless steel.
Points for Attention
| Points for Attention | |
| 1 |
Please clean up settling tank regularly. Ash deposition will cause the incomplete precipitation of dust and desulfurization products. If impurity content of water which flows into clean water tank is too high, it will block pump and spray device so that desulfurization effect will be influenced. |
| 2 |
Feed water flow control: Adjust water flow supply and control the water supply in allowed range. Do not bring liquid water into induced fan and chimney. |
| 3 |
Boiler room operators should seriously record following information in time: the amount of alkali, PH value of water in tank, water addition, PH value of ash water and cleaning dust situation of depositing chamber. |
| 4 |
Check whether the pump, fan and electric motor are heating, whether there is abnormal noise and whether there is seepage water of pump. |
| 5 |
Check whether desulfurization products generate crystallizing, if crystallizing has been generated; please change circulating water in tank in case of clogging nozzle and affecting desulfurization effects. |
| 6 |
Circulating water should be changed when blow is out in case that there is no water but burning. |
| 7 |
Equipment failure: Firstly, please find the causes of the malfunction, if the problem can be solved individually, actions should be taken immediately, if the individual can not solve the problem, please inform the responsible officer and boiler operators as soon as possible. When stopping running the equipment for repair, the fan should be firstly turned off, and then the pump. |
