Box-type membrane separation device

Abstract

The invention discloses a box-type membrane separation device, and relates to the technical field of membrane separation equipment. The box-type membrane separation device comprises a box with an opening in the top; a box cover is arranged at the top of the box in a matching manner; a plurality of supporting plates are arranged up and down inside the box longitudinally side by side; the opposite ends of the supporting plates are fixedly connected to the side surface of the box through connecting plates; a plurality of mounting holes are formed in the surfaces of the supporting plates side by side; membrane assemblies are arranged inside the mounting holes through fixing mechanisms; the tops of the membrane assemblies are connected to a first liquid conveying pipe through connecting pipes;the first liquid conveying pipe is positioned above the box cover; one end of the first liquid conveying pipe is connected to a liquid draining pipe; the bottoms of the membrane assemblies are connected to a second liquid conveying pipe through connecting pipes; the second liquid conveying pipe is positioned below the box; one end of the second liquid conveying pipe is connected with a liquid inlet pipe. Through the arrangement of the membrane assemblies in the box with good sealing performance and coordination with the fixing mechanisms, the service lives of the membrane assemblies are effectively prolonged, and the production cost of a product is reduced; the box-type membrane separation device is suitable for popularization.

Description

technical field [0001] The invention belongs to the technical field of membrane separation equipment, in particular to a box-type membrane separation device. Background technique [0002] Membrane technology is known as the water treatment technology of the 21st century, and it is the fastest-growing and most widely used technology in the past 40 years. The basic principle of the application of membrane technology in water treatment is: the water molecules in the aqueous solution (raw water) have the ability to pass through the separation membrane, while the solute or other impurities cannot pass through the separation membrane, and the aqueous solution (raw water) is treated under the action of external force. Separation to obtain pure water, so as to achieve the purpose of improving water quality. Compared with traditional water treatment technology, membrane technology has the advantages of energy saving, less investment, easy operation and high treatment efficiency. The...
