Deodorization and Waste Gas Treatment Project of Chitianhua Paper Industry in Guiyang City, Guizhou Province

PROJECT OVERVIEW

Chitianhua Paper Industry Company is a bamboo pulp production enterprise with advanced technology and large single series output in the world today. It is one of the first pilot enterprises for circular economy in China. In recent years, Chitianhua Paper Industry Company has invested 200 million yuan to accelerate the technological transformation and upgrading of waste gas and wastewater recycling and utilization, and to protect the beautiful Chishui River with practical actions. The original design of Chitianhua Paper Industry Company had an odor collection and treatment system, but after the industrial transformation of 100000 tons of natural color pulp structure, the original system's processing capacity was insufficient. To this end, Chitianhua Paper Industry Company has invested 30 million yuan in the odor optimization and renovation project, adding five sets of odor treatment systems and significantly improving the processing capacity.

PROJECT INTRODUCTION

Source of exhaust gas

Mainly sourced from pulping, washing, bleaching, papermaking processes, etc

Exhaust gas volume

30,000m³/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

Guiyang City, Guizhou Province

ECLEAR SOLUTION

Design air volume

30,000m³/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 treated exhaust gas is subjected to catalytic oxidation adsorption in the YQWT system, passes through the filter material layer, and the foul odor gas is transferred to the composite adsorption mixed phase. It is then decomposed and purified through neutralization adsorption purification.

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

Odor components	Odor inlet indicators	Odor discharge indicators	Exhaust pipe height
H2S	≤100mg/m3	≤0.6kg/h	15m
NH3	≤40mg/m3	≤0.6kg/h
C2H6S	≤50mg/m3	≤0.6kg/h
Odour	≤3000	≤800
