HEAT UTILIZER Russian patent published in 2008 - IPC F28D15/02 

FIELD: heat and power industry; other industries; production of the heat utilizers.

SUBSTANCE: the is intended for heat utilization from the waste waters and can be used in the heat-and-power engineering. The heat utilizer contains the evaporation and condensation sections and the heater made in the form of the bundles of the heat-exchange tubes passing through these sections and partially filled with the intermediate heat-carrier. The evaporation section is made in the form of the expansion tank with the central siphon offset, the internal surface of which has the longitudinal ribbing, and the bundle of the heat-exchange tubes is disposed on its external surface and connected in the lower and upper cross-sections by the collectors. The section condensation is made in the form of the body, inside which in the center there is the tube for delivery of the waste waters and the bundle of the heat-exchange tubes is disposed along the perimeter inside the body and is connected in the lower and upper cross-sections by the collectors. At that the lower collectors of the section of condensation and the upper collectors of the evaporation section are connected among themselves by the U-shaped tubes. The upper collector of the section of condensation is supplied with the fitting tube with the valve used for filling-in of the heat-exchange tubes with the heat-exchange medium, and the body of the section of condensation is supplied with the fitting tubes of feeding of the cold water and withdrawal of the hot water. The invention allows to use the reclaimed heat for heating of the water used for the industrial and household needs, to simplify the design and to reduce the heat and power inputs.

EFFECT: the invention ensures usage of the reclaimed heat for heating of the water used for the industrial and household needs, simplification of the device design, reduction of the heat and power inputs.
