Original Abstract
Current interest in environmental issues is closely linked to issues of waste treatment. Produced waste is mostly categorized as dangerous and other types of waste. Waste which is not suitable for material utilization may be processed in several other ways; it may be landfilled, thermally processed, etc. Though landfilling may seem like the best solution, it causes piling of produced waste, polluting of surroundings and underground water, spread of infection and so on. Processes of thermal decomposition are necessary not only for detoxication, but also for reduction of negative impacts on the environment. At the same time, waste serves as secondary source of energy. However, thermal processing has its drawbacks as well. These include release of emissions into the atmosphere, residual waste and water pollution. Waste incinerators are equipped with various types of technologies for flue gas cleaning which require various physical-chemical technological procedures and devices to efficiently clean flue gas. Dry, semi-dry and wet flue gas cleaning methods are used for capture of gaseous components of acidic nature (SO2, HCl). This paper focuses on wet cleaning. This paper presents results of research at two stage equipment for flue gas cleaning and describes new prototype of first stage wet cleaning of flue gas. This spheric O-element prototype replaces old type Venturi scrubber equipment for intensive contact between gas and liquid. Paper will also give results from experimental measuring of efficiency of HCl absorption in various operating conditions.
