Design And Research Of Integrated Filter Feeding System Based On Fuzzy Control

The problem of air pollution brought by the economic developmentbecomes increasingly serious. Dust pollution is an important factor affectingthe atmospheric environment. The traditional dust removal equipments havethe shortcomings of low intelligence and efficiency with the fine particles inthe field of polluted air purification. It is difficult to meet the air qualityrequirements alone due to the mechanism, structural characteristics and alsothe complex application environments of the dynamic processing andemission standards. The blower24hours running at full capacity caused hugewaste of energy power. With the continuous improvement of the national airquality standards, to develop energy-efficient filter which adapts even higherthan the new standards are not only the needs of production but also therequirements of the national environment protection. Raised against thissituation and on the research of cyclone and bag filter technology, a noveldust removal technology was proposed, analyzed its feasibility andadvantages in the removal of industrial dust. The main innovation of thepaper includes:The cyclone-bag compound dust removal technology was an organiccombination of cyclone technology with bag approach. The cyclone bag dustremoval technology was proposed and a novel filtering method was studied inthis essay on the base of analyzing the cyclone and bag filtering method. Anew novel integrated filter was designed and achieved.Combined with frequency control technology, the new dust removaldevice system was designed in the paper, focused on the adaptive variablespeed feeding control method and system to achieve an efficient and stableworking with pulsing processions objects and complex condition. For the dynamics of the dust intake process and the requirements of thesystem control, Fuzzy control strategy and algorithm was studied and appliedin this paper, the fuzzy PID controller was designed and the system modelwas analyzed. The pressure feeding system of the new dust removal devicewas successfully simulated and studied with MATLAB fuzzy toolbox andsimulation environment. The results expressed that fuzzy PID control showedan excellent control performance in the system response characteristics,steady precision, adjust speed and anti-jamming compared with theconventional PID control.Finally, the test system combined with the design requirements wasestablished and did preliminary comparative experiments. The results showedthat the novel integrated device’s particle capture rate of above5μm particles,5μm--1μm fine particles and complex mixture of particles could respectivelyreach99.9%,97%and98%. With the situations of complex inletconcentration, particle size and different dust intake condition, the integrateddevice also had a dust removal rate of over95%, It can also remained at95%with mixed dust inlet concentration change rate and the case of the efficiencyof the wasted air intake, to achieve a composite dust removal device systemto adapt to different dust concentration, particle size, specific gravity changescomplex efficiently and conditions stable operation.
