Alkaline waste etching liquid cyclic regeneration equipment

Abstract

The invention relates to alkaline waste etching liquid cyclic regeneration equipment, which comprises a base, wherein a filtering tank is arranged on the base; the inside of the filtering tank is of a cavity structure; the top of the filtering tank is provided with a feeding opening; a filtering frame is arranged in the filtering tank; a first filtering bed and a second filtering bed are arranged inside the filtering frame; a discharging opening is formed in one side of the bottom of the filtering tank; a conveying pump is arranged at the other side of the bottom of the filtering tank; a first filtering net and a second filtering net are arranged inside the filtering tank; the first filtering net and the second filtering net are arranged above the filtering frame; the first filtering net and the second filtering net are arranged under the feeding opening. The alkaline waste etching liquid cyclic regeneration equipment has the advantages that the filtering treatment effect on alkaline waste etching liquid is greatly improved; the cycle use of the alkaline waste etching liquid is convenient.

Description

technical field [0001] The invention relates to regeneration equipment, in particular to recycling equipment for alkaline waste etching solution. Background technique [0002] Circulating water treatment equipment is a set of system equipment for cooling and water quality treatment of circulating water, including raw water supply pressure part, raw water treatment part, precision filtration part, reverse osmosis supply pressure and reverse osmosis membrane filtration part, and final water storage part, etc. components. The circulating water cooling treatment system is a system for cooling and water quality treatment of the cooling water recycled in the industrial sector. The recycled cooling water is called circulating water. In the process of cooling production equipment or products, the temperature of the cooling water rises. Although its physical properties do not change much, after long-term recycling, some dissolved substances in the water will condense or disappear. ...

AI Technical Summary

Problems solved by technology

The recycled cooling water is called circulating water. In the process of cooling production equipment or products, the temperature of the cooling water rises. Although its physical properties do not change much, after long-term recycling, some dissolved substances in the water will condense or disappear. The accumulation of dust and the growth of microorganisms will cause scale deposition in equipment and pipelines or corrosion of metal equipment and pipelines; therefore, it must be cooled and stabilized to ensure the normal operation of the circulating water system

The existing circulating water treatment equipment is inconvenient to perform multi-stage filtration treatment on alkaline waste etching solution, and it is inconvenient to carry out recycling control on alkaline waste etching solution
