Embodiment Construction

[0004] The processing technology is as follows:

[0005] 1. Add industrial hydrochloric acid with a concentration of 36% to the collected waste residue; the amount added is 8% to 10% by weight, and placed naturally.

[0006] 2. Mix the above materials with the collected diatomaceous earth filter aid waste residue from brewery production in a ratio of 3:1 to 1:1 and stir evenly.

[0007] 3. Thermal regenerative calcination process, the equipment is a rotary kiln, and the hot air in the furnace and the material flow in reverse. The fuel can be fuel oil, gas or coal. The calcination temperature is initially 350°C and the high temperature zone is 850°C. The material is calcined in the kiln for about 40 minutes to 1 hour, and then cooled. Through high-temperature calcination, hydrochloric acid and calcium oxide in the waste residue generate calcium chloride, which can be used as a flux to improve the adsorption and filtration performance of the product. At the same time, the org...

Abstract

This invention relates to a mahogany sulfonate product garbage diatomite filter aid regeneration technique in non-metal mine products, which uses the characteristics of the diatomite self anti-acid and alkali and stable physical properties and the calcium oxide during the production process. Through integral process and by adding muriatic acid, it mixes with the beer factory production garbage diatomite filter aid and regenerates the filter aid by burning and gravity degrading process.

Description

technical field [0001] The invention relates to the regeneration technology of the non-metallic mineral product diatomite filter aid. Background technique [0002] Sulfonate is an additive to improve the performance of lubricating oil. In its production process, a very important filtration process uses diatomite filter aid. After filtering, the waste filter residue is thrown away and becomes one of the sources of environmental pollution. The production of diatomite filter aid is made through the processes of mining, drying, crushing, fluxing and calcination, crushing and winnowing. Its raw material soil requires sio 2 The content is above 85%. Therefore, a large amount of high-quality mineral resources must be consumed. Contents of the invention [0003] The purpose of the invention is to regenerate diatomite filter aid waste residue. The raw material used is the sulfonate production waste of Jinzhou Petrochemical Fine Chemical Co., Ltd. Utilize the physical and che...
