Abstract

An apparatus which absorbs gas that has been discharged from a pipe at a high velocity and which releases the gas to the atmosphere at a reduced velocity and with relatively low noise. The apparatus includes a container which has a container interior, a container inlet through which the gas enters the container interior, and a container outlet, preferably located at the top of the container, through which the gas is released to the atmosphere. The container further includes a container expanded section and a container main section. The container expanded section, which acts to reduce the velocity of the gas, is located intermediate the container inlet and the container main section and has an inner surface cross-sectional area which expands from the container inlet to the container main section. The container also includes deflector vanes for diverting the flow of the gas within the container interior towards the container outlet. The deflector vanes provide the gas flow with a smooth and gradual transition from the container inlet to the container outlet thereby enhancing the flow characteristics and properties of the gas flow within the container and reducing the vibrations and noise level associated with high velocity gas flow and speed reduction. In the preferred embodiment, deflector vanes are attached within the container interior to divert the flow of gas, each vane preferably attached at an angle from horizontal ranging from 20 to 50 degrees.
