Lime sulfur mixture residue recycling method

Abstract

The invention relates to a waste utilization method, and in particular relates to a lime sulfur mixture residue recycling method. The lime sulfur mixture residue recycling method comprises the following steps: placing lime sulfur mixture residues into a muffle furnace, and calcining for 0.5-3 hours at 500-900 DEG C to obtain recyclable lime sulfur mixture residues, wherein the recyclable lime sulfur mixture residues can be taken as a white coating agent, and the white coating agent is prepared from the following components in parts by weight: 5 parts of the recyclable lime sulfur mixture residues, 1 part of lime, 0.5 part of a lime sulfur mixture and 20 parts of water, and the whiteness degree of the white coating agent is more than or equal to 80%. According to the lime sulfur mixture residue recycling method provided by the invention, the recyclable lime sulfur mixture residues obtained by virtue of calcination can be reused to produce the white coating agent or can be taken as calcium oxide instead of raw material calcium oxide to produce the lime sulfur mixture, and thus the resource utilization rate can be increased.

Description

technical field [0001] The invention relates to a waste utilization method, in particular to a method for recycling lime sulfur residues. Background technique [0002] Lime sulfur mixture is a fungicide used in agriculture made from quicklime, sulfur and water. Boiling the lime sulfur medicinal liquid produces a large amount of lime sulfur residues. For lime sulfur manufacturers, lime sulfur residues are solid wastes, which are generally sold at a low price or even lost money to use nearby farmland as whitening agent. Lime sulfur residues are mainly composed of CaO, CaS·S x And lime residue, its useful component CaO has not been rationally utilized. Contents of the invention [0003] Aiming at the above-mentioned technical problems, a method for reusing lime sulfur residues is provided, and the specific technical scheme is as follows: [0004] The method for recycling lime sulfur residues comprises the following steps: [0005] The lime sulfur residue is placed in a m...
