Adsorbent for rust-cleaning and pickling waste liquid treatment and preparation process of adsorbent

Abstract

The invention discloses an adsorbent for rust-cleaning and pickling waste liquid treatment and a preparation process of the adsorbent. Coal powder, sodium chloride, SiO2-CaCO3 crystallized ores, bentonite, nut shell, orange peel, timber, pomelo peel, resin, waste asphalt, waste tire particles, an activating reagent and distilled water are taken as raw materials; the proportions of all the components are strictly controlled, and a traditional adsorbent formula is changed; sources of the SiO2-CaCO3 crystallized ores, the bentonite, the nut shell, the orange peel, the timber, the waste asphalt and the waste tire particles are wide; a finished product adsorbent is granular, and has the advantages of good use effect, convenience in preservation, long shelf life, simple preparation process and low production cost; a water bath heating mode is adopted for easily controlling the water temperature; the temperature environment of preparation is ensured, so that the performance of the adsorbent becomes more stable.

Description

technical field [0001] The invention relates to the technical field of hardware recycling and processing, in particular to an adsorbent for rust removal and pickling waste liquid treatment and a manufacturing process thereof. Background technique [0002] Hardware is obtained through mechanical processing. Hardware is widely used in daily life. Hardware can be recycled and reused, which is of great significance to sustainable development. In the process of recycling hardware, pickling is often used The pickling solution is used to derust the surface of the hardware. The main component of the pickling solution is dilute hydrochloric acid. The pickling solution needs to be treated and then discharged. The pickling solution needs to use an adsorbent during the treatment process. The traditional adsorbent production process is complicated. The production cost is high, and the adsorption effect is not good, which has great limitations. Now there is a lack of an adsorbent for rust...

[0002] Hardware is obtained through mechanical processing. Hardware is widely used in daily life. Hardware can be recycled and reused, which is of great significance to sustainable development. In the process of recycling hardware, pickling is often used The pickling solution is used to derust the surface of the hardware. The main component of the pickling solution is dilute hydrochloric acid. The pickling solution needs to be treated and then discharged. The pickling solution needs to use an adsorbent during the treatment process. The traditional adsorbent production process is complicated. The production cost is high, and the adsorption effect is not good, which has great limitations. Now there is a lack of an adsorbent for rust removal and pickling waste liquid treatment and its manufacturing process to solve the above problems
