Eject foreign matter faster with the Debris Removal System

Depending on the cosubstrates chosen, large quantities of foreign matter can occur in biogas plants. Until now, removal was quite complicated, which is why it pays to supplement the PreMix with the innovative Debris Removal System (DRS) by Vogelsang. It ejects foreign matter separated out while the PreMix is still running. Equipped with the DRS system, the PreMix does not need to be switched off or opened. Compared with conventional solutions, DRS completes the process in one sixth of the time, and can even be partially automated with a corresponding control. In addition, only roughly 15 l of medium is ejected with the heavy material. This not only avoids trouble and irregularities in feeding solid matter, it means that only a little of the suspension needs to be led back.

Features of the Debris Removal System (DRS)

The Debris Removal System is built to be tough and durable. This minimizes maintenance work.

The medium trapped in the heavy matter separator is returned to the machine via a check valve. Only 15 l of heavy material and medium are discharged.

Thanks to a free passage of 180 mm, even larger heavy material is reliably discharged.

Options of the Debris Removal System (DRS)

In the basic version, the slide valve is opened and closed using a hand wheel, and the DRS piston is driven by a manual pump.

Manually monitored by the operator, the slide valve is opened and closed using a hand wheel; however, the DRS piston is conveniently operated hydraulically.

Slide valve and DRS piston are hydraulically operated. The entire process is monitored by a control. Only the catcher has to be emptied manually at the end.

A hydraulic unit suitable for hydraulic operation of the DRS piston and slide valve can also be arranged to save space.

The Performance Control Unit (PCU) for the PreMix or RotaCut RCX is set up for monitoring the DRS in automatic mode. Alternatively, a separate Performance Control Unit (PCU) is available for the DRS.

Debris Removal System operating principle

Removing heavy material during operation

In biogas plants in particular, large amounts of heavy material usually accumulate. Stones, metal parts, porcelain, stoneware etc. get into the process via liquid manure as well as dung, organic waste etc. Separated by a heavy material separator, the final removal has so far involved a great deal of manual effort. In addition to the actual heavy material, large quantities of manure or suspension also escape, which then have to be fed back into the process.

The Debris Removal System (DRS) discharges the separated heavy material during ongoing operation with no need to switch off or open the solid matter feeder or the RotaCut / foreign matter separator. The system discharges the heavy material with only minimal loss of medium (only around 15 l). Compared to conventional solutions, the DRS reduces the work required by up to 80%.

The innovative DRS can therefore help optimize operations wherever large quantities of heavy material arise and the service interruptions necessary for removal are disruptive to the process. In particular, applications in which an interruption in operation is unacceptable or downstream units and process lines being at a standstill causes high costs.
