Method for protecting a rotation separator from icing, and rotation separator

Abstract

The invention relates to a method for operating a rotation separator (1), wherein a gas flow, which is laden with solid and / or liquid particles and originates from an internal combustion engine, is fed to a rotationally driven element labeled as a rotor (3), in which method particles are separated from the gas flow and deposited onto the rotor (3), wherein the rotor (3) is operated at a rotationalspeed labeled as an effective rotational speed in such a way that the particles deposited on the rotor (3) are spun off from the rotor (3) as a result of the rotational motion of the rotor (3). According to the invention, after the internal combustion engine has been shut off, the rotor (3) is set into rotation at the effective rotational speed by means of a so-called separate start (A) while theinternal combustion engine is at a standstill. The invention further relates to a rotation separator (1) that is controlled by a control system in such a way that the rotation separator is operated in accordance with said method.

Description

technical field [0001] The invention relates to a method according to the preamble of claim 1 . Background technique [0002] A method of the same type is known from EP 1 532 353 B1. This known method is used to clean the air flow from the crankcase of an internal combustion engine. On the more general principle of centrifugal separators (which can also be designed, for example, as cyclone separators which do not require rotatable parts but instead have a fluid placed in rotation), a rotary separator is a An embodiment variant in which a rotating component is provided, which is accordingly designated as the rotor. In particular, the rotor can have a plurality of separation surfaces arranged one above the other in a stack, wherein such a rotary separator is also referred to as a disk separator in practice. Within the scope of this approach, such a disc separator is always considered and mentioned as an exemplary embodiment of a rotary separator, without the invention being...

AI Technical Summary

Problems solved by technology

Especially when several short trips are carried out in succession, it cannot be ruled out that an ice layer forms in the rotary separator, which prevents the flow through the rotary separator

For example, the gaps between the individual disks of a disc separator may be closed by such ice, or the bearings of the rotor may freeze so that when the internal combustion engine is restarted, the rotary separator either cannot (or is not balanced) set in rotation , or cannot be flowed through as intended, so that the power of the rotary separator may in any case be partially or completely impaired
