Embodiment 1

[0035] A drying-free solidification material for recycling industrial flue gas solid waste and its application, which is composed of 50% forming agent, 10% modifying agent and 40% catalyst. The preparation method is as follows: the above-mentioned raw materials are input into a mixer according to the proportion and mixed evenly, and then crushed to 150 mesh by a pulverizer to obtain a solid waste solidified material product.

[0036] The application of the present invention includes the following steps: adding 95% of the solid waste (coke powder, blue charcoal powder) and 5% of the solidified material into the mixing homogenizer for mixing and homogenizing; sending the homogenized mixture into the forced mixer for grinding Stirring; send the stirred mixture into a high-pressure molding machine to form agglomerates, which can be used as auxiliary materials and raw materials for reducing agents in calcium carbide plants after 18 hours of natural curing. The test results are show...

Abstract

The invention relates to an industrial flue gas solid waste recycling drying-free curing material and application, and effectively solves the technical problems that the existing pollution treatment method affects the air permeability of a sintered material layer and the strength of sintered ore and cannot be recycled and reused for application, and the curing material is prepared from the following raw materials in percentage by weight: 40-50% of a forming agent, 5-10% of a modifier and 40-50% of a catalyst. Wherein the forming agent consists of polysaccharide sludge, boric sludge and citric acid; the modifying agent is prepared from N-hydroxymethyl acrylamide and dicyclopentadienyl iron; the catalyst is composed of sodium aluminate, calcium aluminate and active magnesium oxide. The material is used for industrial flue gas solid waste solidification treatment, industrial flue gas purification solid waste can be directly solidified into block mass particles through a forming device, the block mass particles can be used as auxiliary materials or raw materials for smelting after being naturally solidified for 8-18 h, and therefore industrial flue gas pollution treatment and solid waste recycling application are achieved.

Description

technical field [0001] The invention relates to the technical field of industrial flue gas pollution control, in particular to an industrial flue gas solid waste recycling-free drying and curing material and its application. Background technique [0002] In the production process of iron and steel, alloy, chemical industry, carbon and other industries, the dust removal system will collect a large amount of iron-containing and carbon-containing dust, polysaccharide sludge, which contains iron and carbon content of 30% to 70%, which is of great value High secondary resources. Most of the traditional treatment adopts low-cost efflux, transfer, back-mixing sintering, cold solidification pellets, etc. The traditional efflux and transfer methods can only be digested on site due to solid waste pollution prevention and discharge permit policies, and cannot be discharged and transferred . The back-mixing sintering method and cold solidification pellets are currently the most used m...
