Preparation system of coal-electricity integrated three-waste-based foamed material and using method thereof

Abstract

The invention discloses a preparation system of a coal-electricity integrated three-waste-based foamedmaterial and a using method thereof. The preparation system is characterized in that: a water-liquid mutual driving unit is used for supplying a foaming agent mixed solution to a novel foam maker through a coil pipe under the driving of a constant-flow constant-pressure pump; desulfurization equipment and compression equipment are sequentially used for treating flue gas to form flue gas liquid, and gasification equipment is used for treating the flue gas liquid to form flue gas to be suppliedto the novel foam maker; a three-waste-based foamed material mixer is used for fully and uniformly mixing a generated foam material and a mixed slurry to generate the three-waste-based foamed material. The comprises the following steps: carrying out desulfurization and compression treatment on flue gas, treating high-salt mine well water, and mixing and stirring fly ash, cement and high-salt minewell water to form the mixed slurry; supplying flue gas and a foaming agent mixed solution to the novel foam maker to generate a foamed material; uniformly mixing the foamed material and the mixed slurry to generate a three-waste-based foamed material; injecting into a self-top-contact region; and injecting flue gas into a worked out section. According to the system and the method, three wastes are scientifically treated and recycled, and the preparation process can be monitored.

Description

technical field [0001] The invention belongs to the technical field of green mines, and in particular relates to a preparation system of a coal-electricity integration three-waste-based foaming material and a method for using the same. Background technique [0002] With the development of the national coal-electricity integrated production model, the development model of "coal-electricity joint operation" has become increasingly mature, which has effectively alleviated the severe contradictions in the coal-electricity industry caused by supply-side reforms, improved energy utilization, and brought relatively Good economic benefits. The coal-electricity integrated production model is distributed in a wide area and involves many enterprises, including Inner Mongolia, Guizhou, Xinjiang, Shanxi and other provinces, and many coal-fired power group companies such as the National Energy Group, China Coal Group, and Tongmei Group. While the integration of coal and electricity bring...

Problems solved by technology

[0003] The treatment and utilization of fly ash, flue gas, and high-salt mine water (solid, gas, and liquid wastes) produced by coal-electricity integration have always been a difficult problem to be solved. The degree of comprehensive utilization is low, and the feasibility of a single method is poor, which is not conducive to large-scale promotion and industrial application

However, in the prior art, there is no device suitable for preparing three-waste-based foaming materials, which is not convenient for the preparation of three-waste-based foaming materials. At the same time, the use method for three-waste-based foaming materials is unreasonable and the utilization efficiency is low.
