Nano-filtration device for dyeing water

Abstract

The invention discloses a nano-filtration device for dyeing water. According to the technical scheme, the nano-filtration device is characterized by comprising a frame body, a plurality of filter pipes are placed on the frame body, the adjacent filter pipes are communicated with one another, a plurality of filter membrane filter assemblies used for filtering wastewater are arranged in each filterpipe, and a pump body used for pumping the wastewater into the filter pipes is further arranged on one side of the frame body; the filter membrane filtering assembly comprises a pipe body, a bottom cover fixed at one end of the pipe body and a top cover fixed at the other end of the pipe body, the diameter of the pipe body is equal to that of the inner wall of the filtering pipe, openings are formed in the top cover and the bottom cover, and nanofiltration membranes are arranged in the pipe body, sequentially laid on the bottom cover and arranged in the length direction of the pipe body in multiple layers. The nano-filtration device has the advantages that the wastewater is filtered, so that the filtered water resource can be recycled, and the waste of the water resource is reduced.

Description

technical field [0001] The invention relates to the field of dyeing water treatment equipment, in particular to a nanometer filter device for dyeing water. Background technique [0002] Dyeing is the process of dyeing fiber materials with color. That is, the physical or chemical combination of dyes and fibers, or the use of chemical methods to generate pigments on fibers to make the entire textile a colored object. There are many types of dyeing equipment: 1. According to the nature of mechanical operation, it can be divided into intermittent dyeing machine and continuous dyeing machine; 2. According to the dyeing method, it can be divided into exhaust dyeing machine, jigger, pad dyeing machine, etc.; 3. The state of the dyed object can be divided into bulk fiber dyeing machine, yarn dyeing machine and fabric dyeing machine. and [0003] After the dyeing machine dyes the fabric, a large amount of waste water will be generated. At present, some dyeing factories usually dis...

AI Technical Summary

Problems solved by technology

[0003] After the dyeing machine dyes the fabric, a large amount of waste water will be generated. At present, some dyeing factories usually discharge the waste water directly, which not only pollutes the environment, but also wastes recyclable water resources, which is not environmentally friendly and energy-saving.
