Apparatus for the extraction of heat from sewage and method for the operation of the said apparatus
Реферат: Abstract of the Disclosure This invention relates to an apparatus for the removal of heat from sewage. Sweage is fed to the top of a tank through an inlet. A connecting line between an inlet and an outlet, fitted with a shut-off valve, comprises, in the vicinity of the said inlet, two hollow bodies in the form of inverted truncated cones arranged in immediate proximity to each other. The area between the said hollow bodies is in the form of a coarse screen. A circular fine screen, extending downwardly, surrounds the said hollow bodies. Located in the space between the fine screen and the wall of the tank are heat exchangers. Located at the bottom of the said tank is an outlet which merges into a riser and is connected, through an elbow, to a sewer. Sweage passes through the coarse screen into the said tank and heat reaches heat-exchangers through the fine screen. As a result of this, almost dirt-free sewage is provided and purification work is substantially reduced.
