1. Application
This machine is development for the wet profession (textile, printing and dyeing, papermaking, foodstuff, leather, chemical industry) which the energy conservation request. it can recycle effectively discharges in the sewage the heat energy to enhance the temperature of the clear water. when reduced the clear water elevation of temperature greatly needs the steam energy consumption, achieved the energy conservation reduces the platoon, the regeneration resources circulation use goal.
2. Features
①. Adapt to process requirements in printing and dyeing plants completely and feature blockage free and corrosion resistance.
②. Specially-designed structure. To make heat change contact surface initiative clean.
③. Easy and flexible installation and small apace. THE basin liquid level dropping variance may adjust.
④. High rate of return.
3. Effect of energy-saving
①.Save much steam: the temperature of washing water is raised from 22℃ to 65 to 70℃ with water heat exchanger. Therefore heating the washing water to the required temperature at 95 to105℃ can not only save much steam but also shorten the heating period, resulting in a higher efficiency.
②.Avoid the adverse effect of cold water on textile and improve the washing effect.
③.Lower the high temperature of waste water 85 to 90℃ to 40℃, which facilitates the treatment of waste water.
The picture shows the use of disc heat exchanger in single machine and sewage respectively. Due to its disc rotating structure, it is necessary to check the rotating joint regularly.
The picture shows the new developed and designed curved plate heat exchanger of our company. The whole machine has no transmission system, which is easy to clean and maintenance free, and gradually replaces the disc heat exchanger.
Calculation formula of investment recovery:
Every 1 degree rise of clean water is 1 kcal / kg of hot card, energy saving per hour of clean water (6x1000) GKX temperature difference degree ÷ 600000 kcal = saving steam / hour Steam saving / hour x working time x steam price = recovery cost price, equipment cost ÷ recovery cost price = recovery cost days
