Technical Field
The utility model relates to an absorption tower sprays especially relates to a high efficiency absorption tower that sprays.
Background
The spray tower is a device for waste gas treatment, and the purification equipment can be used in industrial waste gas treatment.
The working principle is as follows: the acid mist waste gas is introduced into the purification tower through an air pipe, the acid mist waste gas and the sodium hydroxide absorption liquid are subjected to gas-liquid two-phase full contact absorption neutralization reaction through the packing layer, and the acid mist waste gas is purified, dehydrated and demisted through the packing demisting plate and then discharged into the atmosphere through a fan. The absorption liquid is sprayed down at the tower top after being pressurized by a water pump at the tower bottom, and finally flows back to the tower bottom for recycling. The purified acid mist waste gas meets the emission requirements of emission standards. The prior art spray tower has the following problems: because the waste gas contains a certain amount of particles, the filler is easy to block, the mass transfer efficiency is low, the pollution discharge is not clean, the exhaust gas contains a certain amount of spray liquid, the frequent maintenance is needed, the labor cost and the equipment cost are high, and the like.
