Abstract
In order to provide a method of introducing auxiliary material into the flow path of a crude gas stream charged with wet-paint overspray before the crude gas stream passes through at least one filter element for separating the overspray from the crude gas stream, with which method an introduction of auxiliary material into the application region of a paint shop is reliably prevented even in the event of incorrect operation, a method is proposed, which comprises the following method steps: detecting whether there is an adequate crude gas flow through the at least one filter element; and blocking the introduction of auxiliary material into the flow path of the crude gas stream if it is determined that there is not an adequate crude gas flow.
Claims25
Method of introducing auxiliary material into the flow path of a crude gas stream charged with wet-paint overspray before the crude gas stream passes through at least one filter element for separating the overspray from the crude gas stream, wherein the auxiliary material deposits as a barrier layer on surfaces of the filter element in order to prevent these surfaces from being clogged by adhering wet-paint overspray particles, said method comprising the following method steps:
- detecting whether there is an adequate crude gas flow through the at least one filter element;
- and
- blocking the introduction of auxiliary material into the flow path of the crude gas stream if it is determined that there is not an adequate crude gas flow.
Apparatus for introducing auxiliary material into the flow path of a crude gas stream charged with wet-paint overspray before the crude gas stream passes through at least one filter element for separating the overspray from the crude gas stream, wherein the auxiliary material deposits as a barrier layer on surfaces of the filter element in order to prevent these surfaces from being clogged by adhering overspray particles and wherein the apparatus comprises the following:
- a detection device for detecting whether there is an adequate crude gas flow through the at least one filter element;
- and
- a blocking device for blocking the introduction of auxiliary material into the flow path of the crude gas stream if the detection device determines the absence of an adequate crude gas flow.
Apparatus for separating wet-paint overspray from a crude gas stream containing overspray particles, comprising at least one filter element for separating the overspray from the crude gas stream and at least one apparatus for introducing auxiliary material into the flow path of the crude gas stream charged with wet-paint overspray before the crude gas stream passes through the at least one filter element for separating the overspray from the crude gas stream, wherein the apparatus for introducing auxiliary material into the flow path of the crude gas stream comprises the following:
- a detection device for detecting whether there is an adequate crude gas flow through the at least one filter element;
- and
- a blocking device for blocking the introduction of auxiliary material into the flow path of the crude gas stream if the detection device determines the absence of an adequate crude gas flow.
Installation for painting articles, comprising at least one application region for applying wet paint onto the articles to be painted as well as at least one apparatus for separating wet-paint overspray from a crude gas stream containing overspray particles, comprising at least one filter element for separating the overspray from the crude gas stream and at least one apparatus for introducing auxiliary material into the flow path of the crude gas stream charged with wet-paint overspray before the crude gas stream passes through the at least one filter element for separating the overspray from the crude gas stream, wherein the apparatus for introducing auxiliary material into the flow path of the crude gas stream comprises the following:
- a detection device for detecting whether there is an adequate crude gas flow through the at least one filter element;
- and
- a blocking device for blocking the introduction of auxiliary material into the flow path of the crude gas stream if the detection device determines the absence of an adequate crude gas flow.
