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.
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
Operation
1. Firstly, please turn on pump, turn off the door of induced fan, reduce current. Then, open the door of the fan when the fan operates normally. At last, when there is water overflowing at the outlet of water spray tower, please turn on the induced fan.
2. When operating, please observe the operation of water supply system and ensure water supply even and normal.
3. When operating, it is not allowed that there is no water in cylinder. Please check whether the outlet of ash water is smooth regularly and observe the temperature of flue gas and resistance of system.
4. When operating, PH value of water in tank should be tested regularly, when PH value is less than 7, alkali matter should be added to ensure the PH value of circulating water.
5. According to the amount of ash, mist eliminator backwash pump does not need to operate for a long time, it should be controlled well.
6. Water level in processing water tank should be normal before turning on backwash pump. Water level in circulating water tank should be normal before turning on circulating water pump as well. If the water level cannot achieve the requirement, please start clarified water pump so that water in processing tank can flow into circulating tank, as a result, water level in processing water tank is of importance.
7. When turn off device, please turn off induced fan firstly and then water pump.
8. If the device has been rested for a long time, there is necessary to drain water in water pipe and tower and clean up the ash in multi cyclone dust collector.
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
Open the valves of spray devices.
