Working Principle of Net Wet Curtain
02
Horizontal ventilation Mode:
When Exhaust in pig farm passing Fan to Washed filter wall,Exhausts humidity will increase by be spayed and form air & liquid mixing.Partly of Ammonia and dust will be absorb by droplet and fell down the reservoir.Hydrogen sulfide and ammonia and so on will be grasped by Biological bacteria attached on wet net filler module and decomposed. Therefore, Exhaust will be purified.
In order to ensure the activity of biological bacteria, the spray system will automatically adjust PH, spray volume, water replenishment volume and so on based on PH,LF test equipment’s test data. This adjustment keeps Biological bacteria’s Long-term & effective activity
Structured packing media is versatile and can be stacked into block-form, suitable for use in towers. Made of Polypropylene (PP) in colour black. Net Wet Curtain
Net Wet Curtain Longitudinal ventilation:
The working principle of Net Wet Curtain is same with horizontal ventilation.The biggest difference is air flow direction.Longitudinal ventilation can extend the vertical channel height and increase wet net filler module thickness.
In big pig farm or livestock farm with large displacement,Two mod integrated application will achieve outstanding Deodorizing effect.
A net wet curtain, also known as a water curtain or wet screen, is a type of air pollution control device used to remove particulate matter and other pollutants from industrial exhaust streams or air. Here are the key details about net wet curtains:
Working Principle:
A net wet curtain consists of a series of fine-mesh screens or perforated plates arranged in a curtain-like configuration.
Water is sprayed or distributed across the surface of the screens, creating a continuous wet curtain or barrier.
As the polluted air stream passes through the wet curtain, the water effectively captures and removes the particulate matter, dust, and other contaminants.
Pollutant Removal Mechanism:
The wet curtain provides a large surface area for the air-water contact, facilitating the following removal mechanisms:
Impaction: Larger particles collide with the water droplets and are captured.
Interception: Smaller particles are intercepted and removed by the water droplets.
Diffusion: Extremely small particles are captured through the diffusion process.
Advantages of Net Wet Curtains:
Effective Particulate Removal: Net wet curtains can achieve high removal efficiencies, typically in the range of 80-99%, for a wide range of particulate sizes.
Versatility: They can be used to remove various types of particulates, including dust, fumes, mists, and aerosols.
Low Maintenance: The water distribution system and screens require relatively low maintenance compared to other air pollution control devices.
Cost-Effective: Net wet curtains are generally a cost-effective solution for particulate matter removal, especially in large-scale industrial applications.
Applications:
Foundries and metal processing industries: To control the emission of metal dusts and fumes.
Cement and mining industries: For the removal of mineral dusts and particulates.
Woodworking and furniture manufacturing: To capture wood dust and particles.
Chemical and pharmaceutical industries: For the control of process-related particulate emissions.
Power plants and boilers: To remove fly ash and other combustion-generated particulates.
Design Considerations:
Water distribution and recirculation system: Ensuring uniform water coverage and efficient water management.
Pressure drop and airflow: Designing the system to minimize pressure drop and maintain the desired airflow.
Corrosion and scaling: Using appropriate materials and water treatment to prevent corrosion and mineral scaling.
