Due to the advantages of low cost and simple structure,the filter cartridge dust collector is widely used in the purification of industrial waste gas.At present,there are still problems of secondary dust,uneven flow field distribution,and serious erosion of the filter cartridge in the filter cartridge dust collector equipment used in the industry.Therefore,it is particularly important to optimize the internal flow field of the dust removal equipment,improve the dust treatment efficiency of the dust collector,and minimize the energy consumption and maintenance costs of the dust removal system.In this paper,the current intake field filter cartridge dust collector used in the plant is taken as the research object,and the internal flow field of the lower intake filter cartridge dust collector used in the plant is systematically analyzed.In order to obtain accurate conclusions and apply the conclusions to practice,this paper analyzes and compares the results through a combination of numerical simulation and experimental research.It also proposes a method of installing a glyph guide plate inside the dust collector and changing the arrangement of the filter cartridge to improve the flow field inside the current dust collector of the project,increase the service life and dust removal efficiency of the dust collector,and thus reduce the production and maintenance costs of the enterprise.The thesis is mainly divided into the following points:First of all,the dust collector model used in the factory area was numerically simulated.Through simulation analysis of the current filter cartridge dust collector,it was found that there were secondary dust,filter cartridge erosion and other problems inside the dust collector;based on the analysis conclusion,Propose an improved plan to add a new type of font deflector and change the arrangement of the filter cartridge group.Then,according to the improvement plan of the flow field,combined with the installation angle of the glyph deflector,a variety of optimized numerical models were established to study the effect of the glyph deflector with different installation angles on the internal flow field of the filter cartridge duster,and finally obtained The installation angle of the product-shaped deflector with the best distribution of the flow field;and comparative analysis of the flow field environment of the filter cartridge group in different arrangements.Finally,according to the results of the optimized numerical simulation,a deflector is installed inside the dust collector box.Under the actual working conditions of the dust collector,the air velocity and wind pressure of the filter cartridge dust collector are measured by using the instrument.After analyzing the obtained data,the uniformity of the flow field is obtained,and the feasibility of the optimization scheme is verified by comparing with the optimization simulation;And measure whether the particle concentration meets the emission requirements. |
