Abstract

<p>[Problema] Se proporciona un dispositivo de suministro de gas que puede suministrar de manera estable burbujas de aire que tienen un pequeño diámetro dentro de un líquido.<br /> [Solución] Un dispositivo de suministro de gas 1 configurado para suministrar burbujas de aire G dentro de un fluido L incluye: una parte de cuerpo 10 que es un elemento cilíndrico hueco que incluye una salida de descarga 10h en un extremo de la parte de cuerpo desde la que son descargadas las burbujas de aire G, teniendo la parte de cuerpo una superficie interior en la que está formado un agujero de expulsión de gas 10b para expulsar gas; y un elemento saliente 11 provisto en la superficie interior de la parte de cuerpo 10. El elemento saliente 11 está provisto entre el agujero de expulsión de gas 10b y la salida de descarga 10h. Las burbujas de aire G expulsadas desde el agujero de expulsión de gas 10b entran en colisión con el elemento saliente 11 antes de ser descargadas desde la salida de descarga 10h; por lo tanto, pueden formarse burbujas de aire G menores que las burbujas de aire G descargadas desde el agujero de expulsión de gas 10b. En consecuencia, aunque un tamaño del agujero de expulsión de gas 10b se aumente algo, puede reducirse un tamaño de las burbujas de aire G que se expulsan desde la salida de descarga 10h; por lo tanto, puede prevenirse la obstrucción o similar del agujero de expulsión de gas 10b y pueden suministrarse de manera estable las burbujas de aire finas G.<br /> </p><p> [Problem] A gas supply device is provided that can stably supply air bubbles that have a small diameter within a liquid. <br /> [Solution] A gas supply device 1 configured to supply air bubbles G within a fluid L includes: a body part 10 which is a hollow cylindrical element including a discharge outlet 10h at one end of the body part from which the air bubbles G are discharged, having the body part an inner surface in which a gas expulsion hole 10b is formed for expelling gas; and a projecting element 11 provided on the inner surface of the body part 10. The projecting element 11 is provided between the gas ejection hole 10b and the discharge outlet 10h. The air bubbles G ejected from the gas ejection hole 10b collide with the projecting element 11 before being discharged from the discharge outlet 10h; therefore, air bubbles G smaller than air bubbles G discharged from the gas expulsion hole 10b may be formed. Accordingly, even if a size of the gas ejection hole 10b is somewhat increased, a size of the air bubbles G that is ejected from the discharge outlet 10h may be reduced; therefore, clogging or the like of the gas ejection hole 10b can be prevented and fine air bubbles G can be stably supplied. <br /> </p>
