HSUP series vibrating fluidized bed dryers produced by Chenghai Company completely replace any fixed fluidized bed and vibrated fluidized bed drying equipments produced by domestic drying manufacturers; for any solid material, we can always use dual vibrator fluids. The chemical bed completes the drying with the lowest energy consumption. In the cellulosic sodium industry, our dual-mass vibrating fluidized bed is the best in the country, even internationally, in terms of principle, performance, function, product quality and other aspects, and solves the shortcomings of all traditional fluidized beds in China. Completely avoids phenomena such as sticky wall, partial flow, dead bed, allergies, leakage, and low yield.
• This series of equipment adopts a new type of vibration mechanism and structure for the fluidized and drying of materials, and integrates a series of advanced technologies to solve the fixed fluidized bed produced by domestic dry manufacturers and the traditional two-side vibration motor driving forms. All the disadvantages of vibrating fluidized bed eliminate the traditional backward technology of fixed fluidized bed and vibrated fluidized bed;
• Chenghai's two-body fluidized bed vibration is stable, excitation force is completely uniform and synchronized, the bed surface is positioned by the leaf spring, the bed surface is always on a plane, plus horizontal air distribution technology, to ensure that under any circumstances, Any loose material will not die, go, drift, agglomerate, sticky bed, back mixing; this kind of vibratory conveying method can enlarge the bed, the length of bed is up to 20 meters, the material with high humidity and poor flowability Large-bulk materials, materials with large particle size differences, fiber materials, leaf-like materials, ultrafine powder materials, light-weight materials, heavy-density materials, etc. can be stably transported.
• The HSUP dual-mass vibrating fluidized bed adopts a powerful automatic control system and scientific monitoring optimization technology, so that the system always completes the process requirements with the lowest energy consumption. Our equipment saves energy than any domestic dryer manufacturers' equipment. %the above.
• This vibration mode achieves an ideal Plug Flow (SUB-FLUIDIZED) state. The Plug flow fluidization state is an ideal fluidization state. The wind speed is just below the fluidization velocity of the material. From the fluidized state, the material's There is no obvious violent movement between the particles. From the material movement speed point of view, the movement of the material realizes a plug flow movement. Every time the bed vibrates, the distance each particle moves forward is constant, and the particles are Evenly forward, no back mixing; drying in the plug flow state requires the lowest amount of air, the drying process requires less air volume, smaller auxiliary equipment, lower exhaust heat loss, and saves a lot of energy; Since the material is in a sub-fluidized state, the particles do not mix in the longitudinal and lateral directions of the bed, there is no backmixing phenomenon, and the difference in the residence time between the particles is close to zero. The advanced material first goes out (First in, first out). , The product's movement speed and dwell time, temperature and humidity can be precisely controlled, so the product will not be overheated, sintered, and allergic; similarly, in the state of the plug flow fluidization The material layer has no bias flow, channel flow, and hysteresis, and the fluidization is stable. The Plug flow fluidization state can ensure the utilization of thermal energy of the hot air. The contact between the hot air and the material, the full exchange of heat and mass, and the hot air without the phenomenon of blow-through, can be precise. The exhaust gas temperature is controlled so that the hot air after the exchange of heat and mass is basically at saturation humidity, and the corresponding temperature is also the lowest; the Plug flow fluidization state is dried at a lower wind speed, the treatment of the product is mild, and there is no friction between the particles. Destruction does not destroy the appearance of the product; in the case of Plug flow, the forward transport of the material is basically completed by the vibration of the fluidized bed. Many products can achieve this ideal state through a combination of fluidization and sub-fluidization technologies. Chenghai's sub-fluid bed material thickness between 5-60cm.
• 0.2-5m/s airflow velocity covers all fluidization spectra, enabling rewetting agglomeration granulation, spray granulation, coating, agglomeration granulation, inert particle drying, drying, cooling, high temperature sterilization , high temperature calcination, high temperature reaction, inert gas closed cycle drying, solvent recovery drying, hot air circulation drying and other processes.
• Frequency-adjusting vibration frequency, precise control of the product's residence time (5-160min), so that the product temperature and humidity are very uniform; avoid hot anaphylaxis, avoid transitional drying, avoid heat loss; unique horizontal airflow technology, forming air cushion, the material with Bed plate isolation, avoid sticky bed, hot allergy, agglomeration;
• The scope of application is greatly broadened, and all material with a particle size of less than 60mm is fluidized and transported. The material that requires a temperature of up to 600°C can be processed. Therefore, high-temperature drying of large materials can be performed, and high-temperature drying is an effective measure to save energy.
• The bed surface can be designed arbitrarily, the material residence time can be adjusted freely, and the drying temperature can be adjusted freely: there will be no contradiction between the drying time required for the material and the material retention time that the bed can guarantee; on the premise of fixed bed area, the material residence time According to the actual drying temperature of the material corresponding to the theoretical drying time can be arbitrarily adjusted without worrying about the material prematurely walk through the bed.
• Features a belt dryer for more efficient drying. Material that can only be treated with a belt dryer. Due to the limitation of the hot air speed of the belt dryer, the air flow of the belt dryer is limited under the same dry area, and the vibrating fluidized bed of the double mass body has a large wind speed range, a large air volume range, and a drying time exceeding the belt type. The scope of the dryer, so the drying strength, capacity, speed, effect greatly exceeds the belt dryer. Especially in the low-temperature drying, the dual vibrated fluidized bed can better reflect the advantages.
• Large-scale equipment, a single bed area of ​​44m 2 , high heat capacity, huge output, no need for two beds in series; for materials with large processing requirements and long drying time, only one bed is required to complete; for any material , Drying at any temperature, there is no contradiction between the required bed area and the required drying time, so the drying temperature is free to choose, the bed area is arbitrarily designed.
• Adopt advanced evaporative cooling technology to cool new concepts of most products and save energy.
• User-friendly design, easy installation and disassembly of equipment; no manual cleaning of leakage materials, equipment self-cleaning device; no daily maintenance, lower maintenance costs; everywhere for the operator to consider, easy to operate;
• The equipment can increase the auxiliary facilities such as stirring, screening, mixing, smashing, etc.
• High degree of automation and stable performance; The PLC system automatically adjusts the air volume according to the feed volume and humidity by calibrating the product temperature and the exhaust gas temperature, so that energy will not have additional losses; due to the stable performance of the equipment, the material will not stick to the bed and go Bias, channel flow, stagnation, backmixing, delamination, scabbing, etc., so there is no need for special personnel to monitor the operation.
• The built-in dust removal device of the equipment design captures the dust entrained by the airflow and falls directly into the bed, eliminating the need for extra cyclone, bag dusting, spray cleaning and other dust collectors, and does not require an additional dust pneumatic conveying system.
