Description
Technical Field
The invention relates to the technical field of membrane separation, in particular to a small-scale membrane separation device.
Background
The membrane separation technology has the functions of separation, concentration, purification and refining, and has the characteristics of high efficiency, energy conservation, environmental protection, simple molecular filtration and filtration process, easy control and the like. Therefore, the membrane separation technology has been widely applied to the fields of food, medicine, biology, environmental protection, chemical industry, metallurgy, energy, petroleum, water treatment, electronics, bionics and the like, generates great economic benefits and social benefits, and becomes one of the most important means in the separation science at present. The membrane separation phenomenon is widely present in nature, particularly in living bodies, but human recognition and research thereof has passed a long and tortuous path. Engineering applications of membrane separation technology were started from desalination of sea water in the 60's of the 20 th century-1960) professor lobbies and sorilagin made the first high flux and high salt rejection cellulose acetate paper membranes with a symmetric structure, from which reverse osmosis was moved from laboratory to industrial use. Then various novel membranes are successively appeared, and in 1967, DuPont company in the United states firstly develops a hollow fiber membrane component taking nylon-66 as a membrane material; in 1970, a Pemiasep B-9 hollow fiber membrane module with aromatic polyamide as a membrane material was developed, and the highest prize of the chemical engineering of CockParteick in 1971 was obtained. From this reverse osmosis technology, there has been a rapid development in the united states and subsequent use throughout the world. Meanwhile, microfiltration and ultrafiltration technologies are also developed correspondingly. The membrane separation technology can be applied to the fields of food, medicine, biology, environmental protection, chemical industry, metallurgy, energy, petroleum, water treatment, electronics, bionics and the like, and particularly, the ultrafiltration ceramic membrane is applied to various industries, such as heavy metal wastewater treatment and recovery. The existing traditional membrane separation technology equipment can cause that the purity cannot meet the requirement when certain fine materials are separated, thereby affecting the quality. Due to state of the art limitations, inorganic membranes are mainly only microfiltration and ultrafiltration grade membranes, mainly ceramic and metal membranes.
