Description
Technical Field
The utility model relates to a cleaning structure applied to an RO water making machine, and belongs to the field of RO water making machines.
Background
RO is an abbreviation for English Reverse Osmosis, chinese means Reverse Osmosis. The general way water flows is from low concentration to high concentration, and once pressurized, water flows from high concentration to low concentration, i.e. the principle of reverse osmosis: since the pore size of RO membrane is one million (0.0001 micron) of hair, it is generally invisible to naked eyes, and the bacteria and virus are 5000 times of it, so only water molecules and partial mineral ions can pass through, and the water produced at the place is called "fresh water"; other impurities and heavy metals are discharged from the waste water pipe, and the water at the position is called as 'concentrated water'. The process of producing fresh water by RO reverse osmosis is to control the fresh water output by adjusting the discharge of the concentrated water, namely when the discharge of the concentrated water is large, the fresh water output is small; the discharge amount of the concentrated water is small, and the fresh water output is large.
The concentrated water generated during RO production operation is discharged completely, and the concentrated water generated during RO cleaning and disinfection is recycled.
The RO is cleaned and disinfected by cleaning and disinfecting agent with a certain concentration, and the inner and outer membranes of the RO are continuously washed by circulation, so that the cleaning and disinfecting effects are achieved. The concentrated water generated in the process is led into the intermediate water tank through a special recovery pipeline and is collected with fresh water to continue circulating.
However, the existing circulating pipeline is large in flow rate of concentrated water, and all the water after RO enters the intermediate water tank from the concentrated water pipeline, so that fresh water is difficult to enter the intermediate water tank, cleaning and disinfecting agents cannot enter the RO inner membrane, and the RO cannot achieve the cleaning and disinfecting effects.
According to the conventional cleaning method, only one hose can be directly connected to the draining position of the concentrated water, the concentrated water is led into the top cover of the intermediate water tank to enter the tank body in a split manner, and the reduction pipeline is removed after the cleaning and disinfection are finished, so that time and labor are wasted.
