Problems solved by technology
[0003] To sum up, the problem existing in the prior art is that there is still a large amount of waste in the treatment of velvet cleaning wastewater, and the treatment is not perfect. Only the PH treatment of the wastewater has been carried out, which cannot reach the industrial water treatment standard. The environment has caused great harm and reduced the production efficiency of enterprises

The invention belongs to the technical field of purification equipment, and discloses a waste water recovery device after velvet making and cleaning, which is provided with a cleaning box, and one end of the cleaning box is connected with a solution mixing box and an adsorption box; the other end of the adsorption box is connected with a distillation chamber; The bottom of the distillation chamber is connected with a water storage bucket; the side of the distillation chamber is connected with a collector; the bottom of the water storage bucket is provided with a water outlet; the water outlet is provided with a dense filter; the water outlet It is connected with the solution mixing box through pipelines. Through multi-layer filtration and multiple treatments, the present invention filters all kinds of impurities after velvet cleaning and separates reusable raw materials, so that NaOH can be reused, greatly saving costs and improving production efficiency.
Description
technical field [0001] The invention belongs to the technical field of purification equipment, and in particular relates to a device for recovering waste water after velvet making and cleaning. Background technique [0002] At present, silicon materials are widely used in daily life, and the production volume of silicon wafers is also increasing day by day. After a series of processing procedures, silicon wafers need to be cleaned and textured. The purpose of cleaning is to eliminate various particles adsorbed on the surface of silicon wafers. type of pollutants. There are mainly oil stains and metal impurities on the silicon surface in the waste water from texturing cleaning, and excess NaOH solution is put in during the texturing process. The traditional wastewater treatment is only PH treatment of the wastewater, and a large amount of NaOH is wasted, which reduces the cost of the enterprise. production efficiency, wasting production resources. [0003] To sum up, the pr...
