Title
(EN) DEVICE FOR DRYING PRODUCTS SUCH AS IN PARTICULAR PURIFYING STATION SLUDGE
(FR) DISPOSITIF DE SECHAGE DE PRODUITS TELS QUE NOTAMMENT DES BOUES DE STATIONS D'EPURATION
Abstract
(EN)
The invention concerns a device for drying sludge derived from urban or industrial wastewater purifying stations using solar energy, produced in the form of a greenhouse (1) comprising a slab or floor (2) whereon is deposited the bed (3) of sludge to be dried, means (4) being provided for turning over the sludge spread on said floor and driving it forward along the drying device, the latter further comprising ventilators to renew the air contained in said greenhouse. The invention is characterized in that said ventilators (6) are positioned on the means (4) turning over and driving forward the sludge bed.
(FR)
Dispositif de séchage de produits tels que notamment des boues provenant de stations d'épuration d'eaux résiduaires urbaines ou industrielles mettant en ouvre l'énergie solaire, réalisé sous la forme d'une serre (1) comportant une dalle ou plancher (2) sur lequel est déposé le lit (3) de boues à sécher, des moyens (4) étant prévus pour assurer le retournement des boues épandues sur ledit plancher et leur progression le long du dispositif de séchage, ce dernier comporte en outre des ventilateurs pour assurer le renouvellement de l'air contenu dans ladite serre, caractérisé en ce que lesdits ventilateurs (6) sont positionnés sur les moyens (4) assurant le retournement et la progression du lit de boues.
