Device for cleaning of air filters

Abstract

A device for cleaning particle filters, includes an enclosure in which at least a number of particle filter can be placed, heating elements for heating the enclosure, elements for supplying air into the interior of the filters to be cleaned, heat exchange elements arranged in the enclosure for heating the air that is supplied to the particle filters, which air is used for burning of particles in the filters.

1 . Device for cleaning of particle filters, comprising an
 enclosure in which at least a number of particle filter can be placed,   heating means for heating of the enclosure, means for air supply into the interior of the filters to be cleaned,   heat exchange means arranged in said enclosure for heating of the air that is supplied to the particle filters, which air is used for burning of particles in the filters.   
     
     
         2 . Device according to  claim 1 , wherein the air supply means comprises an air pipe conduit, that the heat exchange means comprises a number of loops of the air pipe conduit, which loops are arranged in the enclosure. 
     
     
         3 . Device according to  claim 2 , whereby the air supply means further comprises a source of pressurized air and means for controlling the air to the filters. 
     
     
         4 . Device according to  claim 2 , wherein it further comprises temperature sensors for the respective filter, for sensing the temperature inside the filters during burning. 
     
     
         5 . Device according to  claim 3 , wherein data from the temperature is used for controlling the amount of air to the filter for controlling the burning. 
     
     
         6 . Device according to  claim 5 , wherein it further comprises a source of carbon dioxide, connections between the carbon dioxide source and the respective particle filter and control means for controlling the supply of carbon dioxide to the filters for controlling the burning.
