Embodiment 1

[0029] A method for preparing a carbonized organic matter adsorbent, comprising the following steps:

[0030] Step 1. Prepare materials, in parts by weight, including the following materials: 60 g of crop straw, 10 g of starch, 15 g of carrageenan, 10 g of silica gel, and 5 g of aluminum oxide;

[0031] Step 2. Put the crop straw into the carbonizer for carbonization treatment. After cooling the carbonized straw, put it into the activation machine to activate the carbonized straw. The activated straw needs to be put into the cleaning cleaning inside the machine;

[0032] Step 3. After the cleaning is completed, a solid-liquid separation device is needed to separate the carbonized straw from the fixative liquid, so that the cleaning water inside the straw can be further discharged;

[0033] Step 4. Put carbonized straw, starch, carrageenan, silica gel and alumina into the mixing device after discharge, then heat the mixing device in a water bath, and fully stir the raw materia...

Abstract

The invention belongs to the field of adsorbent production, and particularly relates to a carbonized organic matter adsorbent preparation method which is prepared from the following materials: 60-70 parts of crop straw, 10-20 parts of starch, 15-25 parts of carrageenan, 10-20 parts of silica gel and 5-15 parts of aluminum oxide. The invention has the following beneficial effects: by designing the main formula of the crop straw, starch, carrageenan, silica gel and alumina as the adsorbent and designing the matched preparation method for production, the crop straw can replace wood to produce activated carbon, so that wood waste can be reduced, the environment can be protected, and the production cost can be reduced. And the strength of the adsorbent can be improved through the proportioning of the formula.

Description

technical field [0001] The invention belongs to the field of adsorbent production, and in particular relates to a method for preparing a carbonized organic matter adsorbent and a solid-liquid separation device. Background technique [0002] Adsorbents are also called absorbents. This substance allows the active ingredient to attach to the surface of its particles, turning the liquid micro-compound additive into a solid compound, which is conducive to the implementation of uniform mixing. It is a solid substance that can effectively absorb some of its components from a gas or liquid. Has a large specific surface area, suitable pore structure and surface structure; has a strong adsorption capacity for adsorbates; generally does not chemically react with adsorbates and media; is convenient to manufacture and easy to regenerate; has excellent adsorption and mechanical properties . [0003] In the prior art, when producing adsorbents, after cleaning the carbonized raw material...
