Abstract

Patente de Invenção: <B>"PROCESSO E DISPOSITIVO PARA A PROTEçãO DE PESSOAS E/OU DE PRODUTOS CONTRA PARTìCULAS CARREGADAS PELO AR"<D>. A presente invenção refere-se a um dispositivo e a um processo para a separação de pelo menos dois espaços físicos (1, 2) e para a diminuição da transmissão de partículas carregadas pelo ar entre os espaços físicos, para a proteção de pessoas e/ou produtos (26) contra as partículas carregadas pelo ar, onde a pessoa se encontra pelo menos parcialmente no primeiro espaço físico (1), e os produtos (26) no segundo espaço físico (2), no qual é usado pelo menos um jato de ar laminar (13) de ar purificado para a separação, caracterizado pelo fato de que é gerada com ar purificado em pelo menos o segundo espaço físico (2) pelo menos uma corrente de ar de deslocamento de baixa turbulência (14) perto do pelo menos único jato de ar (13), sendo que a pelo menos única corrente de ar de deslocamento é dirigida predominantemente para a mesma direção como o pelo menos único jato de ar (13).Invention Patent: <B> "PROCESS AND DEVICE FOR THE PROTECTION OF PEOPLE AND / OR PRODUCTS AGAINST PARTICLES LOADED BY THE AIR" <D>. The present invention relates to a device and a process for the separation of at least two physical spaces (1, 2) and for reducing the transmission of airborne particles between physical spaces, for the protection of people and / or products (26) against airborne particles, where the person is at least partially in the first physical space (1), and products (26) in the second physical space (2), in which at least one jet is used of laminar air (13) of purified air for separation, characterized by the fact that at least the second physical space (2) is generated with purified air at least a low turbulence displacement air stream (14) close to the hair least single jet of air (13), with at least the single displacement air current being directed predominantly in the same direction as the least single air jet (13).
