Abstract
"APERFEIçOAMENTOS INTRODUZIDOS EM DISPOSITIVO DIFUSOR DE FLUXO DE AR PARA VENTILAçãO DE GRANDES AMBIENTES FECHADOS". Trata esta patente de um dispositivo difusor de fluxo de ar para dutos verticais de ventilação forçada, permitindo uma perfeita distribuição omnidirecional do ar que percorre o duto, de maneira a garantir a renovação uniforme do volume de ar existente no recinto. Em linhas gerais, a novidade consiste de um dispositivo difusor ( 1 ) de fluxo de ar para instalação em dutos verticais ( 2 ) de ventilação forçada presos ao teto ( 3 ) de um galpão industrial ou outro ambiente fechado semelhante, dispositivo este fabricado em chapa metálica, ou confeccionado em fibra de vidro, fixado à extremidade inferior do duto por suportes ou tirantes ( 4 ) presos ao corpo central ( 5 ) do próprio dispositivo e à parede do duto por meio de parafusos, o mencionado corpo central exibindo formato cilíndrico ou cónico, tendo a extremidade superior fechada para impedir a passagem axial de ar, das laterais deste corpo derivando um conjunto de chapas triangulares encurvadas ( 6 ), dispostas em posição quase vertical, do rebordo inferior (7 ) de cada uma destas chapas derivando uma superfície plana ( 8 ) que o interliga ao rebordo superior ( 9 ) da chapa vertical que lhe é contígua, e assim sucessivamente, cada um destes pares ( 6 )/( 8 ) de chapas definindo uma guia predisposta para receber e direcionar uma parcela do fluxo de ar insuflado pelo ventilador, o difusor podendo apresentar de quatro a oito guias."IMPROVEMENTS INTRODUCED IN A AIR FLOW DIFFUSER DEVICE FOR VENTILATION OF LARGE CLOSED ENVIRONMENTS". This patent deals with an air flow diffuser device for forced ventilation vertical ducts, allowing a perfect omnidirectional distribution of the air that flows through the duct, in order to ensure the uniform renewal of the air volume in the enclosure. Generally speaking, the novelty consists of an airflow diffuser (1) for installation in vertical forced-ventilation ducts (2) attached to the roof (3) of an industrial building or similar enclosed environment, which is made of sheet metal. or made of fiberglass, fixed to the lower end of the duct by brackets or tie rods (4) attached to the central body (5) of the device itself and to the wall of the duct by means of screws, said central body having a cylindrical or the upper end is closed to prevent axial air flow from the sides of this body by deriving a set of curved triangular plates (6) arranged almost vertically from the lower lip (7) of each of these plates deriving a surface connecting it to the upper edge (9) of the adjoining vertical plate, and so on, each of these pairs (6) / (8) of plates defines Not having a guide arranged to receive and direct a portion of the air flow inflated by the ventilator, the diffuser may have from four to eight guides.
