Paper industry
PROJECT OVERVIEW
The production of pulp and paper generally consists of processes such as pulping, washing, bleaching, and papermaking. The papermaking industry pulp includes alkaline pulp, chemical mechanical pulp, and mechanical pulp. The occurrence and discharge of pollutants in its wastewater vary greatly depending on the different pulping methods, raw materials, pulp yield, papermaking varieties, and the presence or absence of chemical recovery. However, they generally contain a large amount of suspended solids, BOD, COD, and some toxic substances, and are usually treated using a combination of physicochemical and biological methods. The main odor components are organic gases such as methanol, formic acid, acetic acid, unsaturated fatty acids, etc.
PROJECT INTRODUCTION
Source of exhaust gas
Mainly sourced from pulping, washing, bleaching, papermaking processes, etc
Exhaust gas volume
35,000m³/h
Composition of exhaust gas
Organic gases such as H ₂ S, NH ₂, methanol, formic acid, acetic acid, unsaturated fatty acids, etc
Project location
Leshan City, Sichuan Province
ECLEAR SOLUTION
Design air volume
35,000m³/h
Design process
YQWT spray absorption process
Preprocessing system
After being collected, the exhaust gas enters the YQWT pre-treatment section through pipelines, and the acidic gases (such as H ₂ S) in the exhaust gas are neutralized and washed using alkaline solution. Using multi-stage fillers and filter materials to adsorb and purify acidic gases (such as H ₂ S), alkaline gases (such as NH ₂), VOCs, etc. in the exhaust gas.
Adsorption purification system
The pre-treatment waste gas undergoes catalytic oxidation and adsorption in the YQWT system, passes through the filter material layer, and is transferred to the composite adsorption mixed phase. It is then decomposed and purified through neutralization adsorption.
Exhaust emission system
The exhaust gas treatment and emission system consists of explosion-proof fans and high-altitude emission pipelines to achieve exhaust gas emission standards and heights.
COMPLIANCE REQUIREMENT
