Spray Tower

The spray tower, also known as a wet scrubber or wet dust collector, is an important activated carbon production equipment in an activated carbon plant. The spray tower uses water to contact the dust-laden gas and separates the dust from the gas by washing.It is used to capture coarse dust particles larger than 10 to 15 microns and is used for cooling and conditioning. The specific liquid consumption is low - only 0.5 to 8 liters per cubic meter of clean air. It can effectively remove odors, sulfur compounds, phenol, formaldehyde and other impurities.

The design of the spray tower scrubber features a cylindrical vessel with inlet and outlet pipes for air flow and nozzles or sprayers for distributing the liquid. One or more layers of nozzles are located in the upper portion of the housing to spray the scrubbing liquid. The scrubbing liquid has a droplet size of 0.025 to 0.04 inches and effectively flushes the gas being cleaned, which moves in a countercurrent flow (from bottom to top) at a velocity of 2.3 to 5 ft/sec. At higher velocities, moisture entrainment occurs and dust is deposited on the inner surface of the scrubber outlet pipe.

The exhaust gas is introduced into the purification tower by the wind pipe. Through the packing layer, theexhaust gas and the absorption lquld are tully exposed to the absorption and neutrallzation reaction ot the gasliquid two phase. After the exhaust gas is purified, the fan is discharged into the atmosphere by the dehydrationof the mist removal plate and the mist eliminator, The absorption liquid is pressurized by the pump at the bottomof the tower and then sprayed down at the top of the tower. Finally, it is recycled to the bottom of the tower forrecycling. The purified acid mist exhaust gas is lower than the national emission standard.

The process and product have the characteristics of simple structure, low energy consumption, high purification efficiency and wide application range. They can effectively remove water-soluble gases such as hydrogen chloride gas (HCl), hydrogen fluoride gas (HF), ammonia (NH3), sulfuric acid mist (H2SO4), chromic acid mist (CrO3), hydrocyanic acid gas (HCN), alkali vapor (NaOH), hydrogen sulfide gas (H2S), and formalin (HCHO). The acid mist waste gas is introduced into the purification tower through the air duct. After passing through the packing layer, the waste gas and the sodium hydroxide absorption liquid undergo a gas-liquid two-phase full contact absorption and neutralization reaction. After purification, the acid mist waste gas is dehydrated and defogged by the demister plate and then discharged into the atmosphere by the fan. The absorption liquid is pressurized by a water pump at the bottom of the tower and sprayed down at the top of the tower, and finally refluxed to the bottom of the tower for recycling. The purified acid mist waste gas meets the emission requirements of the Guangdong Provincial Local Emission Standard, which is lower than the national emission standard.
