GAS PURIFICATION PLANT Russian patent published in 2008 - IPC B01D46/32 B01D53/06 

FIELD: engines and pumps.

SUBSTANCE: plant incorporates a filter chamber with branch pipes to intake contaminated gas and to discharge purified gas, a device to create the filter material vertical flows, a hopper for fresh filter material, a collector for waste filter material and a device for returning the filter material. Inclined flat plates are arranged in two vertical rows inside the said chamber. Each of the said first row plates is set with a 150-300 mm gap at an angle of α=30-60° to the chamber horizontal axis, while the second row plates are set in pairs at an angle of β=90° to each other and with a gap between them of 150-300 mm. The device to create the filter material vertical flows is made up of two branch pipes, two plate gates, two rectangular section diffusers with the distribution flat plates arranged inside the said diffuser at an angle of γ=0-70° to the device vertical axis. The contaminated gas intake branch pipe is open to the contaminated gas duct, the purified gas discharge branch pipe in open to the gas duct, the fan and the branch pipe discharging purified gas into atmosphere.

EFFECT: higher efficiency of gas purification and higher reliability of the plant operation.
