Foundry Emissions

Increased pressure to reduce pollution from foundry emissions

Foundries around the world are the backbone of modern metallurgy, casting molten iron into engine blocks, tools, frying pans and many other everyday objects. Unfortunately, the process generates hazardous, health-threatening air pollution. Among other, foundry emissions such as carcinogenic BTEX (benzene, toluene, ethylbenzene and xylene) and foul smelling amines.

Technical principle:
INFUSER’s CLIMATIC industrial system uses a combination of scrubbers and Gas Phase Advanced Oxidation (GPAO) to remove pollution from foundries. GPAO imitates and accelerates the natural self-cleaning mechanisms of the Earth’s atmosphere in a closed reactor system, and captures emissions before they pollute the environment.

By eliminating the need to force air through static filters with limited capacity, the system avoids large pressure differences and can therefore purify air using significantly less energy than con­ventional methods. Energy consumption can also be optimized because the treatment system can be actively tuned to match the load. Initially, ozone is mixed with the polluted exhaust. The mixture is irradiated with high intensity UV light which transforms ozone into OH radical molecules. These are extremely reactive towards most pollutants, transforming these into aerosol particles which may be filtered off using an electrostatic precipitator. As a final treatment stage, a catalyst removes residual ozone.

Intelligent power management system:
It is a unique feature of the CLIMATIC for foundries that the system only uses the amount of energy required to clean the pollution at any time – the CLIMATIC will go into sleep mode when the pollution is below the threshold emission levels. Sensors can be placed in the production sending a signal to the CLIMATC when the pollution load increases, the CLIMATC will then within 7 seconds be at full power.

FAQ

Frequently asked questions

What are the waste products from the CLIMATIC system?
The only waste is water, but compounds are partly or fully oxidizes in the vapor phase

Will the CLIMATIC system clean the particles in the intake?
The CLIMATIC will partially oxidize existing particles, but is cases of heavy particle loads, the most practical solution is to remove the particles before the CLIMATIC, e.g. using a cyclone or a bag filter.

Is it difficult to change the modifications of the CLIMATIC if the emission changes?
CLIMATIC is based on a modular design, which allows for modification of the number and order of the modules.

Can there be indirect toxic reactions?
The emission air will always be tested in order to identify possible indirect reactions

How often does the system require service?
It is recommended that the system is serviced every 3 month

How often does the system need to be cleaned?
The cleaning and maintenance is dependent on the type and amount of pollution. But, most installation requires cleaning twice per month.
