Description

(54) Hot water separation plant

The purpose of the invention is to separate hot used water from cold water to preheat the domestic water.

This is accomplished by a thermally insulated well having water channels formed by the wall and the water inlet ducts delimited by a partition wall with partitions whose height is less than the well height, with channels extending downwardly and upwardly through outlet openings into the well so that A outlet plate is provided with a slope to the opposite wall of the sump, and a register for the flow of water from the water line is arranged meanderingly above the sump, with an opening e overflow located at the bottom of the sump.

The invention relates to a device for separating hot used water.

Today's recycling of wastewater heat from eg bathrooms, laundries, kitchens and various facilities in the water pre-heating industry due to the necessary mixing with cold water brings little heat gain and therefore their realization is rare. from the waste water, which is located directly at the waste water generation, behind the dirt trap a hot water separator, which drains the hot water in a thermally insulated pipe to a thermally insulated sump with heat exchange elements · This device is suitable for investment purposes only where the sump is away from wastewater generation ·

This drawback is remedied by the hot water separation device according to the invention, which consists of a thermally insulated sump, in which one wall, into which the inlet pipe of used water flows from the sludge, is formed by channels bounded by a separating wall and partitions. height is smaller than sump height · Ducts open at the bottom and at the top into the sump space so that at the level of the upper outlets there is a plate inclined to the opposite wall of the sump · Above the plate there is a meandering register for water flow from the water main At the bottom of the sump there is a drain with overflow.

The advantages of the hot water separator are not only higher heat recovery from the used water, but also savings in investment costs, since it removes the hot water separator at its origin and also the cost of thermal insulation of the pipeline.

An exemplary embodiment of a device for separating hot used water is shown schematically in the attached drawing, where a vertical section through a separator sump is shown.

According to the depiction of the hot water separation device 1, consists of a thermally insulated sump 2 having vertical ducts 60, which are smaller than the sump height, The channels 2 utilize downstream and downstream apertures 2 into the sump space so that an inclined plate 8 is disposed at the level of the upper apertures 2 with a slope to the opposite wall of the sump. A register 2 for meandering the tap water 2 is provided. · Outflow 10 with overflow is located at the bottom of the sump £

In the hot water separator, the waste water is led through the sediment trap directly to the heat insulated sump separator 8 via separate hot inlet separators formed by vertical channels 8 at the bottom and upwards leading to the sump space 8 and by changing the cross-section into the separator. water against the cooler water in the sump causes spontaneous flow of hot water upwards, from where it flows on an inclined plate 8 between the ribs of the pipe register 6, in which water flows from the water main to the after heater and cooled water flows into the lower part of the sump 6 from where it is discharged ·

Claims (1)

SUBJECT VIMIDIZU 232 013 It is hindered for separating hot used water, characterized in that it consists of a thermally insulated sump (1), which has a vertical channel (4) delimited by a separating wall (5) near the wall (2) with the supply pipe (3) from the mud. with partitions (6) whose height is less than the height of the well (1), the channels (4) being discharged at the bottom and at the top through the outlet openings (7) into the chamber (1) so that a wide plate (8) is disposed with an inclination to the opposite wall of the well (1) and above the inclined plate (8) a register (9) is provided for the flow of water from the water main, where outlet / 10 / with overflow ·
