Abstract
The cleaning of industrial gases from dust is one of the most significant current environmental protection problems. The search for new, more advanced and effective ways to clean dust gases and dust collector designs is based on the diversity of technological conditions for dust formation, the physicochemical properties of gases and trapped particles, and an increase in technical and economic requirements for cleaning processes. When cleaning hot or chemically aggressive gases and capturing abrasive dust, the use of electrostatic precipitators, bag, fibrous and granular filters is often associated with difficulties in protecting the devices from harmful factors or ensuring sufficient cleaning efficiency. The design features of slotted filters permit their use in solving such problems. An engineering method for calculating slotted filters developed on the basis of theoretical ideas and experimental studies is used to model and design slotted filters with specified performance indicators to ensure high cleaning efficiency and low hydraulic resistance. This technique is based on theoretical patterns of filtration using basic dust particle deposition mechanisms on isolated cylinders in relation to the stationary stage of the filtration process. A computer program that simulates the process of cleaning dusty gases in slotted filters has been developed. This makes it possible to determine the optimal operating parameters, design dimensions and regeneration conditions of slotted filters based on a specified cleaning efficiency and hydraulic resistance, taking into account the properties of dust and gas during prolonged continuous operation of the filter.
