Claims

[Scope of Claim for Utility Model Registration] 1 a. A drain recovery tank that recovers return steam from steam-using equipment and separates it into a gas layer and a liquid layer, and b. A drain recovery tank that sucks the liquid in the drain recovery tank and supplies it to a boiler. c) A service tank that stores make-up water; d) A make-up water pump that pumps make-up water in the service tank; e) Transfers make-up water from the make-up water pump into the air layer of the drain collection tank. A drain recovery device comprising: make-up water control means for supplying water to the drain to recover heat held by the gas layer and controlling the level of the liquid layer in the drain recovery tank. 2. The make-up water control means has a jet nozzle that injects the make-up water into the air layer of the drain recovery tank, and a diffusion means that causes the make-up water jetted from the jet nozzle to collide and turn into droplets. A drain recovery device according to claim 1 of the utility model registration claim characterized by: 3. The drain recovery device according to claim 2, wherein the diffusion means is constituted by the inner wall of the drain recovery tank. 4. The diffusion means includes an inverted bowl-shaped diffusion member that is installed below the top wall of the drain recovery tank and turns a portion of the make-up water sprayed upward from the jet nozzle into droplets, and a jet nozzle that is installed in the center of the diffusion member. A drain according to claim 2 of the utility model registration claim, characterized in that the drain has a nozzle member that causes the remainder of the make-up water injected from the drain to pass through a diffusion member and collide with the top wall of the drain collection tank. Collection device.
