Delivery Time:20 work days
Certification:ISO9001:2008
Production Description
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.
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. |
Installation and Precautions
When installation, equipment should refer to general assembly drawing from the bottom to the top sequentially. it can also be installed according to the number of each section since there are numbers attached on tower when the equipment is delivered. When the base has been placed to the position, top flange washer should be covered 1-2cm thick furan resin daub from the second section, and then the uppers can be lift one by one. Installation of equipment inlet: orientation of inlet should be determined in advance (ensure the consistency between inlet center of device and the boiler outlet duct center so as to connect with air duct conveniently) Please follow the above steps to install successively. After finishing water tank section, please enter into the device with ladder or scaffold and clear excess cement of cyclone muff, seam between internal section and section should be filled. Please pay attention to the position of water feeding so as to connect the position of spray nozzle and pump. After finishing the installation of tower, please make sure the seal of flange joints.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.
