Vertical bearings - Import export

The Pallmann Depither, series PMS "Centurion" is used for depithing of sugar cane bagasse. The retained bagasse fibers are used for the production of cellulose, the production of fiber boards or for the production of particleboards. Furthermore, the depither can also be used for the preparation of other vegetable raw materials. The machine is designed for the wet preparation, moist preparation or dry preparation processes. Characteristics, Function The material is fed from the top The rotor is vertically arranged with bearings on both sides and equipped with hammers that can be used on both sides The hammers are free swinging and armoured at both sides of the tip Material preparation and separation of the pith from the fiber is performed by means of impact and friction Longer fibers are retained by a screen while the pith and the fines are discharged through a screen with the air flow Pith and fibers are discharged and transported separately Advantages High throughput rate...

The adsorption system (AD) from Venjakob Umwelttechnik serves to concentrate exhaust air flows containing low concentrations of pollutants, and is particularly suitable for removing extremely low to medium concentrations of solvent-based pollutants (VOCs). This machine is characterized by: During the adsorption process, the pollutants are physically retained on the surface of a solid material (e.g. activated carbon, zeolite). The pollutants are then removed /desorbed from the zeolite by means of a small, hot stream of air. Afterwards, the flow of exhaust air from the desorption process is cleaned by means of an exhaust air cleaning system (TI, RTO, CTO). By reducing the volume and by increasing the concentration, the operating costs of the downstream exhaust gas purification system can be kept very low and make autothermal operation possible among other things The rotor is mounted vertically on a shaft with bearing and rotated slowly in the air flow. During rotation, the adsorption and desorption take place simultaneously in separate chambers with cooling on a hydrophobic (water-repellent) incombustible zeolite material. For tough applications, versions can be provided with a removable wear layer and / or higher temperatures of up to 300 ° C for desorption. Two containers are operated alternately. While one of the containers is adsorbing, the other container can be desorbed The adsorption process can be used for smoothing pollutant concentration peaks. If pollutant peaks occur during a process that could lead to a potentially explosive mixture (> 25% lower explosion limit), they cannot be introduced into an incinerator. However, the pollutants may be temporarily stored in an adsorber and then be released during the desorption phase. In certain situations, the installation of an additional fixed bed adsorber (molecular sieve) may further enhance the process (safety, operating costs).
