Example Embodiment
[0025] Example 1
[0026] The flue gas is produced by a fully automatic coal-fired boiler, and the flue gas volume is 300Nm 3 / h, supplemented by SAG-410 aerosol generator to add an appropriate amount of coal-fired fly ash to the flue gas to make the dust concentration in the coal-fired flue gas 4850mg / m 3 , Where PM 2.5 The concentration is 172mg / m 3 . Along the flue gas flow direction, there is a flue gas humidification device, an electric dust collector, a low-temperature economizer, and a limestone / gypsum flue gas desulfurization system. The electrostatic precipitator has a three electric field structure, the cathode is a conventional acupuncture electrode, and the distance between the plates is 0.30m. The heat exchange tube of the low-temperature economizer is made of finned tubes and made of ND corrosion-resistant steel. The wet desulfurization tower adopts a spray tower with a diameter of 200mm and a tower height of 4500mm, and a baffle demister is installed on the top of...
Example Embodiment
[0027] Example 2
[0028] Add polymeric ferric sulfate and polyether modified silicone to the atomized hot water sprayed into the flue gas humidification device to form a chemical agglomeration agent solution. The mass percentage composition of the agglomeration agent solution is: 0.05% polymeric ferric sulfate, 0.005% poly Ether-modified silicone, the rest is the same as in Example 1. Tested by the WJ-60B Pitot tube parallel automatic dust sampling instrument, the dust concentration at the outlet of the electrostatic precipitator and the outlet of the desulfurization tower are respectively 37mg / m 3 , 13mg / m 3 ; Among them, use the electric scale low-voltage impactor ELPI online test, the electric precipitator outlet, the desulfurization tower outlet PM 2.5 The mass concentration is 12mg / m respectively 3 , 5mg / m 3 .
