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.
Accessories
Desulfurization & dedusting specialized non-clogging nozzle. Mainly made of silicon carbide, PTFE, 316L and ceramic.
Installation and Precautions
1.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.
2.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.
3.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)
4. 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.
5. Please pay attention to the position of water feeding so as to connect the position of spray nozzle and pump.
6. After finishing the installation of tower, please make sure the seal of flange joints.
| 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
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.
