Abstract

The invention relates to a heat exchanger for heat recuperation from contaminated water. Draining takes place through a syphon whose action at each drain instant is broken through an air intake which is exposed when a suitable amount of liquid is drained. <IMAGE>

Claims (4)

7903938-4 kan bibehållas i kärlet samt att god kontaktverkan för värme- överföring erhålles mot det inre kärlets mantelyta. Slam och partiklar sjunker mot botten, vilken utformas med lutning mot avloppet. När det yttre kärlet fyllts upp till sådan nivå att hävertverkan erhålles sker snabbt en avbördning av en viss mängd vatten. Den avbördade volymen Skall vara minst så stor att vatten i hävertledningen 6 omsättes helt. Häverten har givits sådana.dimensioner att även de tyngsta förekomman- de sedimenterade partiklarna följer med ut. Uppvärmt vatten från det inre kärlet 3 tas ut genom ett rör 10 vid kärlets överdel. Det yttre kärlet låär försett med ett bräddavlopp ll vilket även kan nyttjas för avledning av skum och flytan- de partiklar. Genom en avstängningsventil 12 kan hävertled- ningen 6 temporärt stängas varigenom vattenytan höjes och rensas från flytande föroreningar. Värmeväxlaren är utvändigt försedd med ett hölje l3 av värmeisolerande material. De båda kärlens volymer avpassas var för sig till aktuella flöden så att erforderliga kontakttider för värmeväxling erhålles. Inom uppfinningens ram kan flera utföringsformer före- komma. Yttre och inre kärl kan ha cylindrisk eller annan form. Inre kärl kan bestå av en eller flera enheter. Hävert kan ha olika utformningsformer. Patentkrav7903938-4 can be maintained in the vessel and that a good contact effect for heat transfer is obtained against the mantle surface of the inner vessel. Sludge and particles sink to the bottom, which is formed with a slope towards the drain. When the outer vessel is filled to such a level that a siphoning effect is obtained, a certain amount of water is drained off quickly. The volume carried must be at least so large that water in the siphon line 6 is completely converted. The siphons have been given such dimensions that even the heaviest occurring sedimented particles follow. Heated water from the inner vessel 3 is taken out through a pipe 10 at the top of the vessel. The outer vessel is provided with a overflow drain 11 which can also be used for diverting foam and liquid particles. Through a shut-off valve 12, the siphon line 6 can be temporarily closed, whereby the water surface is raised and cleaned of liquid contaminants. The heat exchanger is externally provided with a housing 13 of heat-insulating material. The volumes of the two vessels are adapted separately to current flows so that the required contact times for heat exchange are obtained. Within the scope of the invention, several embodiments may occur. Outer and inner vessels may have a cylindrical or other shape. Internal vessels may consist of one or more units. Siphons can have different shapes. Patent claims 1. Värmeväxlare för tillgodogörande av värme från föro- renat vatten innefattande ett yttre kärl (l) för förorenat vatten samt ett eller flera inre kärl för rent vatten eller annan vätska, k ä n n e t e c k n a d av att vätskenivân. i yttre kärlet regleras intermittent genom hävertverkan vil- ken efter en bestämd avbördningsvolym bringas att upphöra ge- nom luftinsläpp vilket åstadkommes då vätskenivân i yttre kärlet frilägger ett luftintag för häverten.A heat exchanger for absorbing heat from contaminated water comprising an outer vessel (l) for contaminated water and one or more inner vessels for clean water or other liquid, characterized by the liquid level. in the outer vessel is intermittently regulated by siphoning action which after a certain volume of discharge is caused to cease by means of air inlet, which is achieved when the liquid level in the outer vessel exposes an air intake for the siphon. 2. Värmeväxlare enligt krav l k ä n nye t e c k n a d av att den är försedd med ett bräddavlopp (ll) och att vätske- nivån i kärlet (l) med en avstängningsventil (12) i anslut- ning till hävert kan temporärt höjas så att flytande partik- lar kan avbördas genom bräddavloppet. 7903938 -læHeat exchanger according to claim 1, characterized in that it is provided with a overflow drain (ll) and that the liquid level in the vessel (l) with a shut-off valve (12) in connection with the siphon can be temporarily raised so that liquid particle lar can be discharged through the overflow drain. 7903938 -læ 3.
