OPTIMIZATION OF BAG FILTER DESIGNS (ON THE EXAMPLE OF CEMENT PLANTS IN THE FERGANA REGION OF THE REPUBLIC OF UZBEKISTAN)

Cement production is one of the most common man-made air pollutants. In this regard, the need for dust collection in this process is obvious. The article presents an analysis of the used structures of dust collection devices in the cement production of the Fergana region of the Republic of Uzbekistan. Methods of tissue filter regeneration are analyzed. The results of experimental studies on the state of synthetic fabric bag filters installed on air purifiers from dust and gas flows are presented. The choice of the standard size, design and the required number of fabric bag filters was made. According to official data [1] currently, 22 cement plants in the Republic of Uzbekistan produce about 11 million tons of cement per year. The development of the construction industry over the past 5 years has dramatically increased the demand for cement in both domestic and foreign markets. In this regard, the Government has set a goal to increase the volume of cement production to more than 20 million tons per year by 2025. This is planned to be achieved not by increasing the capacity of existing enterprises, but by building and commissioning new plants. So, in the Fergana region there are 6 plants with a capacity of 0.5 million tons per year each, which is 1,400 tons. per day, 4 plants of the same capacity are being built and are at the stage of commissioning. At the same time, they ensure 90% cleanliness of the surrounding air pool. There is a share of emissions, existing dust collectors need to be systematically improved and require energy and resource-saving developments. We are conducting research to improve the standard sizes, weaving material design, design and optimal number of synthetic fabric bag filters themselves. Below is a detailed description of their work. The minimum filtering surface of fabrics and the maximum service life of hoses are achieved by combining short filtration and regeneration cycles. However, if the efficiency of cleaning gases immediately after shaking is very low and the sediment is formed slowly, then a high initial speed is necessary to ensure the rapid formation of such a sediment. And then a long period of effective gas purification until the set value ∆ρ is reached. This method is often used when operating high-temperature synthetic filters that operate at low speeds and long filtration cycles. 32 Specialized and multidisciplinary scientific researches Volume 2
