PROJECT INTRODUCTION
Exhaust sources
water pumping station
Exhaust air volume
10,000m³/h
Exhaust gas composition
Hydrogen, methane, ethylene, ethane, propylene, propane, hydrogen sulphide, methyl mercaptan, hydroxy sulphur, carbon sulphide
Project location
Baiyin City, Gansu Province
ECLEAR SOLUTION
Design air volume
10,000m³/h
Design process
YQWT spray washing + YQD biofilter process
Pre-wash systems
The exhaust gases are collected and piped into the pre-treatment stage, where the alkaline/acidic gases in the exhaust gases are neutralised and scrubbed using acid/alkali solution.
biological response system
The pre-treated waste gas passes from the bottom of the biological reaction system from the bottom up through the packing material, and the malodorous gas is transferred from the gas phase to the water-microorganism mixed phase, and is decomposed through the metabolism of the microorganisms fixed on the filter media.
Exhaust gas emission system
Exhaust emission standards and discharge heights can be achieved by selecting a combination of explosion-proof fans and high altitude discharge pipework as required.
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 |

Eclear Environmental RELATED EQUIPMENT
Spray tower
Spray tower, as a type of environmental waste gas treatment equipment, exists. According to its working principle, it can be divided into circulating water spray tower, alkali spray tower, and acid spray tower (also known as acid washing tower). According to the material of the tower, it is divided into fiberglass spray towers, PP spray towers, and stainless steel spray towers. Choose a reasonable spray material and spray process based on the different properties of the exhaust gas. Spray tower is an important industrial waste gas treatment equipment, whose working principle is to use water and power technology to spray liquid or gas in a mist form into the waste gas, in order to remove harmful substances in the waste gas.
Biological filter
A biological filter is a device that uses effective deodorizing bacteria and a reasonable equipment structure to oxidize and decompose large molecules or structurally complex organic matter into simple inorganic substances such as water and carbon dioxide through differentiation. Eclear Environmental Biological Filter has been improved compared to its peers, adopting an integrated treatment process of pre-treatment and deep adsorption of biological treatment to ensure the stability of the intake during the biological treatment stage. At the same time, deep treatment is not configured at the end, which can ensure that the exhaust gas meets the standard when the emission concentration exceeds the design.
Biological strains
Eclear uses specialized composite bacterial strains, including methane producing bacteria, actinomycetes, Bacillus, yeast, and other bacterial strains, which can target the treatment of odorous components such as hydrogen sulfide, ammonia, and VOCs. Adopting a combination of heterotrophic and autotrophic bacteria, according to the composition of exhaust gas, the microbial composition is reasonably proportioned, taking into account the treatment of organic and inorganic pollutants. Microbial strains have high purity, fast biofilm formation, high activity, and high treatment efficiency, which have significant advantages compared to conventional single strains. Combined with biological enzyme products, it effectively and gently catalyzes the decomposition of pollutants by microorganisms, making their decomposition more targeted and achieving better treatment results for odor pollutants.
Washing tower
Washing tower is a mature waste gas treatment equipment widely used in pre-treatment of industrial waste gas treatment, dust removal, and other aspects. Gas enters the tower and fully contacts, adsorbs, and dissolves with the washing liquid inside the tower, achieving purification effect. The design forms of Yi cleaning towers are diverse, and vertical or horizontal structures can be used according to the project application site. The commonly used materials for washing tower equipment include PP, FRP, and stainless steel. PP and FRP are commonly used in chemical absorption towers and have the characteristics of acid resistance, alkali resistance, and corrosion resistance. Stainless steel materials can be used for high-temperature exhaust gas.
Biological deodorization
Biological deodorization is the process of using effective deodorizing bacteria and a reasonable equipment structure to oxidize and decompose large molecules or structurally complex organic matter into simple inorganic substances such as water and carbon dioxide through differentiation. Eclear Environmental Biological Deodorization has been improved compared to its peers, adopting an integrated process of pre-treatment and deep adsorption of biological treatment to ensure the stability of the intake during the biological treatment stage. At the same time, deep treatment is not configured at the end, which can ensure that the exhaust gas meets the standard emission when the emission concentration exceeds the design emission concentration.
Biofiller
Biofillers commonly used include bamboo charcoal, tree bark, fruit shell carbon, volcanic rock, plastic fillers, ceramic particles, etc. Combined with biological strains and enzyme products, they effectively and gently catalyze the decomposition of pollutants by microorganisms, making their decomposition more targeted and achieving better treatment effects on odor pollutants.
