Problems solved by technology
This kind of reverse osmosis membrane water purification unit has high requirements on the working pressure of the reverse osmosis membrane, and due to the structural characteristics of the reverse osmosis element itself, the water production is small and the water production efficiency is low. Under certain circumstances, solutes or ionic compounds may be adsorbed to the surface of the reverse osmosis membrane to contaminate the reverse osmosis membrane, thereby deteriorating the water purification function of the reverse osmosis membrane, and also easily causing clogging, resulting in a decrease in the permeability of the membrane, affecting the The water output per unit time of the device directly affects the water purification efficiency

Abstract
The invention discloses a reverse osmosis water purification unit which comprises a pressure piston, a pre-purification assembly and a reverse osmosis filter element assembly, the pressure piston comprises a piston sleeve and a piston body, and the pre-purification assembly and the reverse osmosis filter element assembly are arranged in the piston body installed in the piston sleeve; the piston body is connected with a pressurizing device for pressurizing the piston body; wherein a water inlet hole is formed in the inner end surface of the piston body, a buffer cavity is formed behind the water inlet hole, a flow equalizing plate and the pre-purification assembly are arranged at the tail end of the buffer cavity, the reverse osmosis filter element assembly is arranged behind the pre-purification assembly and comprises a first ceramic filter element and a second ceramic filter element which are concentrically sleeved, and a reverse osmosis film is formed on the outer surface of the second ceramic filter element; a concentrated water outlet is formed between the rings of the two ceramic filter elements, and a purified water outlet is formed in the ring of the second ceramic filter element. The working efficiency and the working effect of the reverse osmosis film can be effectively improved, and the working stability and the service life of the reverse osmosis film can be ensured.
Description
technical field [0001] The invention relates to drinking water purification device technology in the field of water purification treatment, in particular to a reverse osmosis water purification unit. Background technique [0002] With the continuous improvement of people's living standards, people have higher requirements for drinking pure water, therefore, higher requirements are also put forward for the equipment for producing pure water. The reverse osmosis membrane drinking water purification process is one of the more common water treatment processes currently used in water purification equipment on the market. It is mainly realized by the membrane separation structure and membrane separation technology with reverse osmosis membrane. The reverse osmosis membrane used in the field of water treatment has membrane pores as small as nanometers. The reverse osmosis membrane is used to apply an external pressure higher than the osmotic pressure level on one side, so that wate...
