The cement industry kiln has become more and more urgent for the technical innovation and transformation of the existing dust removal equipment. At present, there are three main schemes for the renovation of cement furnace kiln flue gas dedusting technology: one is to increase the electric field on the existing electric dust removal, increase the dust collection area of ​​the electric dust removal to improve the dust collection efficiency (electricity conversion); the second is to directly use the cloth bag. The dust collector (electrical change bag); the third is to add a bag filter on the basis of the electrostatic precipitator, and adopt the electric bag composite dust removal technology. The three schemes have their own advantages and disadvantages. Among them, the electric bag composite dust collector organically combines the dust collecting characteristics of the electrostatic precipitator and the bag dust collector. Under the condition of meeting the high standard discharge, the workload of the retrofit engineering is relatively small and the floor space is small. The utility model has the advantages of high cost performance, simple operation and maintenance, and the like, and is widely used in the retrofitting of the electrostatic precipitator. The electric bag composite dust remover is a new generation of high-efficiency dust removal equipment that combines electric dust removal and bag filter in a box. The electric bag composite dust removal technology combines the advantages of electric dust removal and bag dust removal. The mechanism is “charged dust collection†and “intercepting filtrationâ€. In the electric field, 80% of the coarse particle dust is removed with a small energy consumption to reduce the dust load of the filter bag; the electrocoagulation between the charged dust particles improves the characteristics of the dust layer and generates a new charge. Mechanism of dust filtration characteristics: heterogeneous charge particles coagulate and form large particle dust, improve the fine particle collection rate; the same charge repels each other and rapidly spreads to form a uniform distribution of gas gel suspension, so that the dust arrangement rules on the surface of the filter bag are Order, fluffy, good gas permeability, high porosity of the dust layer, good exfoliation. Therefore, using a lower cleaning pressure (0.25 MPa), the desired cleaning effect can be achieved, thereby prolonging the cleaning cycle of the filter bag and the service life of the filter bag. In the electric power conversion bag project, the shell structure of the original precipitator, the inlet horn, the ash discharge device, the air distribution device, and the first electric field (or the first two electric fields are retained according to actual conditions and user requirements) are generally retained or updated. Transformation. The latter electric fields will be transformed into bag dust removal areas. After the completion of the transformation, the main structural components of the electric bag composite dust collector can be roughly divided into: the dust removal part of the electric area, the dust removal part of the bag area, the outlet flue, the bypass system, the water spray cooling system of the grate cooler and other parts. The electric-to-electricity bag project needs to consider the characteristics and functions of the major components of the entire precipitator, as well as the interaction and influence of each part, and also consider the modification of the induced draft fan directly related to the precipitator. The following mainly describes the design points of the dust removal part of the electric area, the dust removal part of the bag area, the bypass system, and the water spray cooling system of the grate cooler. First look at the dust removal part of the electrical area. The electric dust removal part is located at the front part of the electric bag composite dust remover. Its function is to perform dust removal on the flue gas entering the dust remover, remove most of the coarse particles in the flue gas and a considerable amount of medium and small particle dust, and greatly reduce the dust entering the bag. Part of the smoke dust concentration and charge the dust particles. In the bag dust removal part, the charge force between the dust particles makes the dust layer formed on the surface of the filter bag relatively loose when the filter bag is filtered, and the filtration resistance is greatly reduced compared with the pure bag filter. In the retrofit design of the electric zone, it is generally necessary to ensure that the dust removal efficiency of an electric field is above 80%. To achieve this requirement, the following conditions must be met: sufficient dust collection area to meet efficiency; uniformity of airflow distribution into the electric field. ; to ensure the restoration of the normal operation of the original equipment electrical area, including the adjustment of the pole spacing, the replacement of the vibrating hammer and the vibrating anvil. The transformation of the electrical area is generally based on recovery and overhaul. For the original equipment to be used for a long period of time and the internal damage of the electrical area is relatively serious, all internal parts will be replaced to ensure the normal operation of the electrical area.
