Description

Electromagnetic whitening system

Technical Field

The utility model relates to a white flue gas processing technology field, concretely relates to electromagnetism takes off white system.

Background

Common white smoke comes from various industries, such as active power generation, biomass power generation, boiler heat supply, waste incineration and the like, and especially the smelting industry generates a large amount of white smoke. White smoke is one of serious environmental air pollution sources, needs to be treated when being discharged, and is treated by electromagnetic de-whitening at present, but the existing electromagnetic de-whitening Bai Renran has a plurality of disadvantages, such as: 1. before entering the electromagnetic whiting device, the temperature of the flue gas from the chimney is higher, and if the flue gas directly enters the electromagnetic whiting device for whiting, the electromagnetic whiting device is damaged due to overhigh temperature, so that the flue gas is cooled before entering the electromagnetic whiting device; 2. after the smoke enters the electromagnetic whitening device through the air inlet pipe, the gas mainly flows through the flow equalizing and guiding section by self and then enters the smoke inlet section. When the smoke output in phosphate fertilizer production is low, the gas self-moving speed is low, the smoke amount entering the cooling section is low, the cooling section idles, and energy waste is caused. When the production is in a peak, the smoke amount is large, and gas meeting the emission requirement cannot be obtained, so that the electromagnetic whitening treatment effect is influenced; 3. and in the process of whitening, the generated dust can form a caking on the inner wall of the whitening tower and support the caking on the inner wall of the whitening tower or the cylinder, especially when a spraying system is used for removing other gases in the whitening tower, the generated dust can form a caking after being combined with sprayed water and acidic water mist and support the caking on the inner wall of the whitening tower or the cylinder, the electromagnetic whitening effect can be influenced or even the electromagnetic whitening effect can be disabled after the dust is not treated for a long time, the dust is manually and periodically cleaned in the radial direction in a conventional mode, but the cleaning is very inconvenient and is easy to cause danger.
