Abstract

The purpose of the solution is hot waste separation water from cold directly at its formation to preheating service water. This is achieved by a recycling device heat from wastewater, the essence of which it consists in that it consists of a dirt trap where the hot water separator is located cold, which is drained into the sewer and hot water is drained by thermal insulation pipes into an insulated sink in which they are inclined, alternately with opposite inclination arranged hollow plates for water flow from the tap order, while at the bottom the sump is located a drain of water with overflow.

Description

The invention relates to an apparatus for recycling heat from waste water.

Today's recycling of wastewater heat from bathrooms, laundries, kitchens, and various industrial water preheating equipment due to the necessary mixing with cold water yields little heat gain and is therefore scarce.

»

The lack of known devices is largely eliminated by the waste water heat recycling plant according to the invention, which consists of a dirt trap in which a hot water separator is located and which is provided with a cold water drain pipe and a hot water drain pipe. water, which is connected to a thermally insulated sump, in which hollow plates for the flow of water from the water main are arranged at an oblique level, and at the bottom of the sump there is a water outlet with an overflow.

Advantages of waste water heat recovery equipment are higher heat recovery from waste water by placing a hot water separator behind the dirt trap directly at the waste water trap, which only discharges the hot water in a thermally insulated pipe into a thermally insulated sump, where layer flows along obliquely arranged hollow plates, through which water from the water supply system flows to the after heater.

An exemplary device for recycling waste water heat is schematically shown in the accompanying drawing, in which a vertical cross-section of a hot water separator with a dirt trap, a hot water duct and a hollow plate well is shown.

According to the illustration of the waste water heat recovery plant, a dirt trap 2 with a basket 2 and a hot water separator 2 is placed directly at the waste water generation, from which cold water is led through a pipe 4 into the sewer and the hot water is led through a pipe 5 Insulation 6, into the upper part of the sump 9, from where it flows along obliquely-mounted hollow plates 2 through which water from the water system removes heat to the hollow plates 7, to the after-heater.

The hollow plates 2 are arranged obliquely, alternately with an opposite incline, in the deck and overlap the sump 9 so that the upper hollow plate 2 forms a narrow gap 10 for the water outlet at the opposite wall of the inlet 8 to the bottom plate T. to drain the water to the other hollow plate 2 and in the bottom of the well 9 there is a drain 11 with an overflow 12.
