Abstract
A method and apparatus are disclosed for treating refuse preparatory to its discharge in a body of water in which air incorporated in the pores and interstices of the material of the refuse is replaced with a liquid, such as water, sea water, or brine, by applying fluid pressure in the range of 200-300 p.s.i. to the refuse containing an added quantity of the liquid.
Claims39
A method of treating refuse including components that are porous and contain trapped air, comprising depositing such refuse in a chamber;
- supplying sufficient liquid to such chamber to assure substantially even fluid pressure throughout such refuse, which liquid has sufficiently low viscosity and surface tension to be capable of being forced into the pores of such porous components;
- and applying fluid pressure throughout such liquid adequate to impregnate enough liquid into such pores to increase the density of such porous components to a value greater than that of water.
Apparatus for treating refuse including components that are porous and contain trapped air comprising means forming a refuse receiving chamber;
- means for supplying fluid to said chamber and for determining when there is sufficient fluid in the chamber to transmit substantially even fluid pressure throughout such refuse deposited therein;
- means for raising the fluid pressure within the chamber to apply a substantially uniform fluid pressure throughout refuse deposited therein, such pressure being adequate to impregnate such fluid into the interstices of such porous refuse components for rendering them more dense than water;
- and means for removing the treated refuse from said chamber.
Apparatus for treating refuse comprising means forming a chamber for receiving refuse therein;
- means for supplying sufficient fluid to said chamber to assure substantially even fluid pressure on all the particles of such refuse;
- means for applying pressure throughout such fluid upon substantially all refuse contained in said chamber;
- means for detecting a predetermined level of fluid pressure in the chamber;
- means responsive to the detecting means for venting such fluid from the chamber after such predetermined level of fluid pressure has been attained therein;
- and means for mechanically compacting the refuse in the chamber into a slug denser than the initial density of refuse placed in said chamber.
