CPE dedicated large non-standard round the fluidized bed dryer, the acid phase chlorinated polyethylene production equipment, the German Technical chlorinated polyethylene boiling drying equipment principle Project Name: "CPE" dedicated large non-standard round the fluidized bed dryer unit Title: Drying Engineering Co., Ltd. Changzhou Hammer domestic water phase method most used process to produce CPE, our company has successfully developed four sets of CPE devices are using advanced hydrochloric acid phase process technology, and through continuous innovation and development, to achieve a high concentration of CPE hydrochloric acid reaction, washed and dried directly, eliminating the neutralization process, so that the product is not salt, higher purity and whiteness, by-product hydrochloric acid can be recycled, no waste acid emissions. Advanced technology allows CPE products with better flexibility, feeling of having a rubber, giving the product the appearance of fine supple, especially for plastics and rubber, and other high-end applications. First, the device design requirements: 1. Material conditions Material name: CPE initial moisture: 10% - 30 (30% basis) final moisture: <0.3% feeding amount: 6000Kg / batch wet material bulk specific gravity: 0.56g / cm2 feed temperature : 15 ℃ (according to room temperature design) product temperature: 35-40 ℃ 2, the process conditions drying methods: Round bubbling bed material in contact with the hot air: Direct heat source and heating method: steam heating (0.6-0.7Mpa 120 ℃) drying inlet air temperature: 110 ~ 120 ℃ (designed to take 120 ℃) ??drying exhaust air temperature: ≤75 ℃ (designed to take 75 ℃) product a material way: Dust round bed main ways: cyclone 3, design weather conditions Atmospheric pressure: 101.325KPa ambient temperature: 15 ℃ Relative Humidity: 80% 4, utilities 4.1 Power Power supply: 380V, 3-phase, 50HZ power: 324.1kw Second, the principle of the process equipment Description: 1, process: CPE wet material under positive pressure air into the dryer wind action, the filtered fresh air heater, heated from the bottom of the hot air blown into the drier dryer. Dryer by stirring and hot air was boiling like the role until the end of drying. Dried CPE material through the dryer discharge valve is discharged into the hopper, after the hopper discharge valve into dried granules CPE silos, fine materials into the grinding smash into the filter separator, CPE powder through the discharge valve by the process Wind will be transported to the packaging of its CPE silo. CPE powder drying process carried by the exhaust gas through the cyclone separator, blown back by the compression dryer exhaust qing chloride is neutralized and absorbed in the scrubber, the washing water concentrated at the bottom of the scrubber washing retracted tank, and regularly add lye by washing after using the pump power cycle, the excess water overflow to the waste water treatment station. Waste gas filter separator grinding pulverized material formed during the emptying smoking induced draft fan, exhaust ensure compliance. 2, the basic principle: Purified hot air from the bottom plate of the dryer perforated flower blown under stirring to full contact with the material, the material was boiling like a dryer. CPE material particles floating in a hot air up and down, collide with each other and inter-mixing, gas, solid mass transfer, heat transfer, so that the material in the water and the residual hydrogen chloride gas sufficiently volatile, so as to achieve the purpose of drying. 3, the actual design process: according to the material properties and the two sides discussed the results of the choice of wind sent equipment and drying equipment boiling gap connection. Material from the After centrifugation, positive pressure away from the fan inlet, fan the material by the wind into the boiling dry bed; 2 sets of equipment sharing a charging port, via a pneumatic control valve feed charge, at the same time open the dried feed The blower and induced draft fan, so that the material is formed under the action of high-speed air flow of drying. Material flow at a certain time of completion of the drying. After drying the material the door open, the material is discharged through the wind outside the host. As the material is centrifugal dehydration, the company considering the material in the centrifugation lump formation, and therefore in the transportation of materials, positive pressure conveying material formed by the fan, so that the material reaches crushing effect. Equipment using the cyclone dust, exhaust dust collection and purification by Shuimo ensure achieve results;
