Using Molecular sieve as desiccant |
How it works
Drying cycle
| The process air enters the dryer through the inlet and is directed into the on-line drying chamber via the inlet valves and lower manifold. The air is evenly distributed through the drying units and passes over the desiccant material, reducing the water vapour content. The dried process air then combines in the upper manifold and exits the dryer via the outlet check valves |
Column changeover
| Before the on-line (drying) and off-line (regenerating) columns change over, the dryer exhaust valve, is closed, allowing the purge air to re-pressurise the off-line columns. This ensures a consistent system pressure and dewpoint when the drying chambers change over. |
Regeneration cycle
| At the start of the regeneration cycle, the exhaust valve of the dryer is closed and the off-line chamber is at full line pressure. The air in the off-line chamber has a dewpoint equal to the air leaving the dryer. The exhaust valve is then opened and the dry air within the chamber expands rapidly as it leaves the dryer via the exhaust silencer, forcing water to be removed from the desiccant material. Once the off-line chamber has de-pressurised, a continuous bleed of dried process air is directed into the off-line upper manifold. This air is known as purge air. With the exhaust valve open, the purge air expands from line pressure to atmospheric pressure and flows downwards through the columns, over the off-line desiccant material. As the purge air at line pressure contains a fixed amount of water vapour, allowing it to expand means the purge air becomes even drier, increasing its capacity to remove water from the saturated desiccant bed. |
Dewpoint Dependent Switching (DDS) system
| With the DDS system installed, the drying cycle remains unchanged, however as the drying chambers are about to change, the DDS system overrides normal operation to fully utilise the drying capacity of the on-line desiccant material. At column changeover, the exhaust valve is closed to allow the purge air to re-pressurise the off-line column, thus ensuring no loss of system pressure. At this time, both drying chambers are at full line pressure, so that no purge air is being used and the dryer is in a state of zero energy consumption. Under normal operation, the drying chambers would proceed to change over automatically, however the DDS system incorporates a hygrometer which is used to monitor the pressure dewpoint of the air leaving the dryer. If the air is drier than the pre-set dewpoint, the desiccant material is only partially saturated and has drying capacity remaining within it, therefore change over is delayed. The hygrometer constantly monitors the outlet dewpoint until the pre-set level has been achieved, at which point, change over will occur. The drying and regenerating cycle will then continue normally until the end of the next column changeover when the DDS system may again extend the drying period as dictated by the outlet air quality. Using DDS will ensure that the energy consumed by BITEMAN is directly proportional to the actual air flow, temperature and moisture loading, not the dryers rated capacity, thus providing signficant energy and environmental savings. |
Details of advantages
| Innovative structure with patents, adopts small desiccant chamber unit  1. Air flow equally and evenly pass through each desiccant chamber 2. Avoid channeling effect which more likely happens in traditional desiccant dryer 3. Small chamber allow no pressure vessel annul inspection 4. Molecular sieve capability is much better than Alumina and silicon desiccant in traditional dryer 5. Easy to maintain and replace factory filled desiccant chamber unit, ensure good performance as beginning 6. PLC controller, Full function touch panel control |

Backhoe loaders are general-purpose tools, and are being displaced to some extent by multiple specialist tools like the excavator and the speciality front-end Loader, especially with the rise of the mini-excavator. On many job sites which would have previously seen a backhoe used,.With the advent of hydraulic powered attachments such as a tiltrotator, breaker, a grapple or an auger, the backhoe is frequently used in many applications other than excavation and with the tiltrotator attachment serves as an effective tool carrier.We are a real manufacturer, looking for agents all over the world
