GAS AND SMOKE PURIFICATION
The capture of gases and fumes that are harmful to the population is one of INTEROZONO’s main operation.
This process is carried out in 5 well- defined phases:
The study of the air needing to be purified (chemical, bacteriological, )
This is the air environment saturated with bacteriological load, odours and particles in suspension from wastewater treatment or industrial processes. We first study the current situation to decide on the best method to improve it.
Air capture (mercaptan gases, bad smells, particles, and others)
The installation contains a suction duct for the air (gases) that are directed towards the purification system. This duct is suspended in the building, warehouse etc., above the hoppers/chutes, or areas to be purified. The cylindrical ducts made of anti-corrosion material.
The extraction calculation (air/gas/particle extraction) is based on obtaining a healthy, clean environment for the workers and that the discharge complies with the regulations in force. For this purpose, the calculation begins with a scale of between a minimum of 10 and a maximum of 30 air renewals per hour. In this case, this data (flow and pressure) indicates the type of fan required: a centrifugal fan made of anti-corrosion material.
Once the air has been captured and channelled through the ducts, it is directed towards the Scrubber deodorisation system “through moisture + ozone”, or through activated carbon filters, manufactured by INTEROZONO with its own technology.
- Scrubber towers made up of special filtering material for contact with different corrosive components, where one of the phases of purification and deodorization of the air is treated (contact between gases – ozone – water – filtering material) is carried out.
- Generation of ozone/air (in situ), for this process the equipment takes the filtered ambient air as raw material to convert it into ozone by means of an electro-physical process that converts oxygen (O2) into ozone (O3). once the ozone has been generated, it is injected into the scrubber towers and into an attached water tank, which supplies water to the pump that injects saturated water with ozone into the scrubber/wash towers. The ozone injected (in air and water) to the 3 scrubber towers is mixed with gases and filled with filter material, the mixing time inside the scrubber towers ensures the deodorization process. this process is based on the oxidation of organic matter in the air. The greater the saturation of organic matter in the air, the greater the filtering mass and the concentration of ozone/m3. Ozone oxidizes the organic matter, obtaining purified air or water (disinfected) without providing chemical products.
- Once the air has passed through the deodorisation system, it is released through a chimney providing air free of unpleasant gases, odours and particles. Complying with the regulations for the discharge of industrial fumes and gases.
Clean air released back into the atmosphere. We will explain those steps in more detail
Una vez realizado el paso del aire por el sistema de desodorización, se realiza el vertido mediante una chimenea de salida al exterior. Aire exento de gases molestos, olores y partículas. Cumpliendo las normativas de vertido de humos y gases industriales.
