상품 소개

The Acid and Alkali Gas Scrubber is a vertical packed absorption tower for centralized chemical exhaust. Contaminated air enters below the packing and rises against a downward flow of recirculated scrubbing liquid. Polypropylene packing increases gas-liquid contact, a spray header distributes the selected absorbent and a top mist eliminator retains entrained droplets before the cleaned stream reaches the outlet. The FRP shell, sump and external piping provide a practical corrosion-resistant construction basis. Despite the product name, one circulation loop is charged for either compatible acid-gas neutralization or alkaline-gas absorption; the actual contaminant mixture determines the liquid chemistry, materials, packing depth, blowdown and monitoring package.

주요 기능

Counter-current gas and liquid flow provides efficient mass transfer through the packed section

FRP tower construction resists many corrosive exhaust and wash-liquid environments when the resin is correctly selected

Polypropylene random or structured packing offers high surface area with moderate pressure drop

A full-width spray header distributes recirculated liquid across the packing bed

The integral sump gives the pump a stable suction source and accommodates controlled make-up and blowdown

A top mist eliminator reduces droplet carryover into the outlet stack or downstream fan

External pump and union connections remain accessible without opening the packed tower body

Chemical dosing and pH or conductivity monitoring can maintain the selected absorption condition

Inspection covers provide access to the demister, spray header and packing support zones

Tower diameter, packing height and circulation rate can be scaled to the verified exhaust duty

고객 제품 관심사

A packed tower works only when the gas chemistry, absorbent, contact time and materials are compatible. Gas loading, salts, solids, pressure drop, liquid carryover and wastewater handling determine the reliable operating window.

Using an alkaline wash for an alkaline gas or an acidic wash for an acid gas provides little neutralization capacityIdentify every significant contaminant and select the recirculating absorbent from the reaction chemistry rather than the tower label.

Insufficient packing depth or excessive gas velocity shortens contact and increases breakthroughSize tower diameter and packed height from the actual airflow, inlet loading, reaction rate and allowable pressure drop.

Precipitated salts or captured solids can channel the liquid and plug packingEvaluate reaction products, maintain blowdown, inspect pressure drop and add solids separation or cleanable pre-treatment where needed.

A resin or gasket that tolerates the inlet gas may fail in the concentrated recirculating liquidCheck shell resin, liner, packing, seal, pump and piping compatibility against both the exhaust and the full wash-liquid composition.

An exhausted or over-diluted wash solution can look normal while absorption capacity fallsUse suitable pH, conductivity, oxidation-reduction or concentration control with defined make-up and blowdown logic.

High outlet velocity or a fouled demister can carry corrosive droplets into the stack and fanKeep separator face velocity within its selected range and provide wash access, drainage and differential-pressure inspection.

기술 매개변수

The displayed basis is a vertical FRP packed tower approximately 1800 mm in diameter and 6000 mm overall height, with a 2000 mm nominal packing zone, integral recirculation sump, one external pump, top demister and small dosing package. The site's fixed ten-row schema uses panel-oriented labels; Panel Thickness therefore records the representative structural shell wall rather than cabinet depth, while Steel Facing Thickness is zero because the corrosion barrier is nonmetallic. Exhaust volume, packing, liquid chemistry, circulation rate, resin system, fan and instrumentation are selected for the actual duty.
