Definitions

• Apparatus for the recovery of the latent heat of a liquid such as waste-water refers to an apparatus of the type in the claim's introductory description.
• the hot waste-water flows down into a thermal-vessel and is stored there until the next outflow of waste-water.
• the thermal-vessel's wall is produced of a high-insulating material, e.g. plasticfoam.
• a container such as a commonly available tapwater tank produced of a heat conductive material, e.g. iron, is submerged in the thermal-vessel.
• the container-part holds the liquid which shall receive the heat energy.
• the waste-water transmits its heat energy to, for example, tapwater in the container-part.
• the waste-water is stored in the thermal-vessel so long as it is necessary to release its optimum heat energy.
• the size of the thermal-vessel is adopted to the prevailant conditions, so for example, it can contain the amount of waste-water that flows out of a bath.
• Waste-water has direct contact with the container-part, therefore resulting in a quick and effective heatflow from waste-water to tapwater. Waste-water and tapwater reach the same temperature relatively quickly.
• the wall of the thermal-vessel is formed internally as a screw-shaped channel.
• This screw-shaped channel or coil completely encircles the container-part.
• thermal-vessel + Container-part to work as a Heat Transference Unit, when warm liquid flows down into the thermal-vessel.
• the claim's characterization is achieved, in that the waste-water's energy is utilized as best as possible.
• the coil fulfills four functions: 1) It can store large quantities of liquid. 2) It strengthens the vesselwall.
• the thermal-vessel's simple developement and production material ensures that no heat emmission transmits to its surroundings.
• the thermal-vessel can be developed very cheaply, and there are many choices of production material.
• the thermal-vessel can be used as an ordinary container for liquid, a watertank, or for example, in connection with a periodic heat source - solar heat.
• the thermal-vessel can be used as a common insulation holder.
• the thermal-vessel can be developed on the site of use and, for example, be cast down into the ground, or placed outside the house.
• the thermal-vessel can if it is. utilized as a part for changing heat, be supplied with a drain-cock in the bottom in respect to sludge-rinsing possibilities, but when the cost of the thermal-vessel is so little, it should be thought that the thermal-vessel can be replaced by a new one if there is need for that.
• the container-part can be supplied with a coil-insert, where the inflow of, for example, tapwater is in the bottom through the centre of the coil-insert, and the outflow of tapwater at the top, after running through a screw-shaped channel or coil.
• a coil-insert where the inflow of, for example, tapwater is in the bottom through the centre of the coil-insert, and the outflow of tapwater at the top, after running through a screw-shaped channel or coil.
• the thermal-vessel would be completely insulated if provided with a thermal-lid.
• Fig. 1. shows the elaborated form for the apparatus according to the invention. The drawing is in sectioned perspective.
• Fig. 2. shows the container-part's coil-insert in perspective.
• Fig. 3. shows the elaborated form for the apparatus according to the in vention. The drawing is in section.
• Fig. 1. shows the elaborated form for the apparatus according to the invention.
• the drawing is in sectioned perspective.
• the warm waste-water flows down into the thermal-vessel K, through the livery pipe t, and runs through the coil S.
• the waste-water is now stored in the coil S, which encircles the container B.
• the container B is suplied inside with a coil-insert P.
• the coil-insert P is formed with a screw-shaped channel or coil s.
• the substance which shall recieve heat from the waste-water flows into the container through the coil-insert P's centre tb, whereafter it runs through the coil s and drains at the top through ab.
• the next emtyring of waste-water takes place, it flows into the thermal-vessel K in the described way, therewith the earlier-emtied waste-water is discharged through the coil S and flows out at the bottom, then up through the discharge pipe a.
• Fig. 2. shows the container-parts coil-insert P.
• P can be constructed of, for example, plastic or plasticfoam.
• Fig. 3. shows the elaborated form for the apparatus according to the invention.
• the drawing is in section and shows a typical container with a coil-insert P.
