Waste Water Heat Recovery Machine

Evolution of Waste Water Heat Recovery Machine Through Generation

In 1970's waste-water-heat-recovery-system was applied, but early days machines caused jamming problems made it not so effective. Now i 21st century development in multipurpose waste water filtering system made it very effective.

evaluation	Simple heat exchanger plate type, shell and tube type	Deformation heat exchanger In order to prevent machine jamming from waste-water-filtering, water flowing tube size increased (increase in water flowing tube size caused flowing speed reduced which eventually caused jamming) decrease in performance	heat exchanger with auto waste-water-filtering system size of water flowing tube is decreased again, and to prevent jamming, auto waste water filter was mounted to a new generation	heat exchanger with upgraded auto waste-water-filtering system In 3rd generation product filtering performance was significantly improved, causing 30% increase in heat exchanger performance, and 50% increase in filter performance maintenance can be made anywhere around the world through internet, and best life span is made in this generation
problems	Heat exchanger waste water jam	Heat exchanger waste water jam	waste water jamming was minimized, but heat exchanger and filter's performance went down	no problem

Global Network Ensaver

Flow of Waste Water Heat Recovery Machine

1. Supplied water is supplied from manufacture system (Winter : 0.5°c, Summer : 26~28°C)
2. Coolant, condensate sent to hot water tank
3. Heated water sent to manufacture facilitiese
4. Steam used for production
5. Waste water discharged

1. Heated waste water takes heat exchange with supplied water through ENSAVER and cooled waste water is discharged
2. Supplied water heated through ENSAVER and sent to hot water tank
3. Heated water sent to manufacture facilitiese
4. Steam used for production
5. Waste water discharged
