Many times, we reduce costs and improve efficiency, energy efficiency, cost reduction, and profitability while maintaining the same number of fully automatic washing and dewatering machines and detergent quality.
The basic mechanism of continuous water washing is to replace the water around the fibers in the fabric with a solution with lower dirt content, allowing the dirt inside the fibers to diffuse into the new washing solution. This process is repeated until the washing process is completed. In order to reduce the consumption of water during the cleaning process of the fully automatic washing and dewatering machine and achieve the purpose of cleaning.
1. Countercurrent washing
Countercurrent refers to the process in which the flow direction of the detergent is opposite to the direction of the fabric's movement. In a fully automatic washing and dewatering machine, the washing solution is added to the last washing tank and sequentially flows in reverse into the other washing tanks in this washing equipment. In a separate washing tank, water is added from the outlet of the fabric and flows out from the place where the fabric enters this tank. When the fabric passes through the sink, the flow of water in the sink continuously supplies the fabric to gradually reduce the amount of dirt on the fabric. Countercurrent not only saves energy, but it is also a fundamental method for modern water washing processes.
2. Increase washing temperature
The most effective way for a fully automatic washing and dewatering machine to achieve the purpose of washing in a short period of time is to improve the diffusion system of pollutants. The diffusion system is the amount of dirt molecules carried on a fabric that diffuse into the washing solution per unit time. There are many factors that affect the diffusion coefficient, and temperature is one of the main factors affecting the diffusion coefficient. As the temperature increases, the diffusion system coefficient increases because the activity energy of the molecules in the washing solution increases, reducing the concentration of pollutants in the fiber surface boundary layer. The saturation state of the fiber surface boundary layer is disrupted, resulting in an increase in the amount and speed of dirt on the fiber entering the washing solution, and an improvement in the diffusion system. In addition, due to the increase in temperature, the surface tension and viscosity of water decrease, which can accelerate the expansion and separation of pollutants on the fibers. An increase in temperature can also reduce the affinity of dyes and other pollutants to fibers, thereby accelerating the exchange rate of the boundary layer. So, increasing the washing temperature can significantly increase the diffusion system.
The fully automatic washing and dehydration machine achieves high efficiency and energy conservation through methods such as countercurrent water washing and increasing washing temperature.
