Description

Technical Field

[0001] The utility model relates to the technical field of extracting char from coal gasification slag, in particular to a device for extracting char from coal gasification slag. Background Art

[0002] Coal gasification is a chemical process that converts coal into synthesis gas (primarily composed of hydrogen, carbon monoxide, and small amounts of carbon dioxide and methane) by reacting it with oxygen and water vapor under high temperature and high pressure. This technology offers a new approach to energy utilization, particularly in countries with abundant coal resources.

[0003] During the coal gasification process, the solid residue is called coal gasification slag. Its main components include:

[0004] Charcoal: The residual char in coal that does not participate in the reaction contains a certain calorific value and becomes a resource.

[0005] Minerals: such as ash and other non-combustible materials, mainly composed of silicon and aluminum components.

[0006] Organic matter: organic matter that is partially not converted during the reaction.

[0007] Among them, the carbon remaining in the coal gasification slag has a high calorific value and good adsorption properties and can be recycled for a variety of purposes, such as:

[0008] Fuel: can be used as a low-cost heat source.

[0009] Adsorbent: can be used in wastewater treatment, gas purification and other fields.

[0010] Soil improvement: Provides a good source of silicon and water retention for farmland.

[0011] Synthetic materials: Carbon-based materials can be prepared for use in catalysts, batteries, etc.

[0012] The recovery and utilization of carbon in coal gasification slag has important economic value and environmental significance, so the development of efficient carbon extraction equipment is particularly important.

[0013] Therefore, in order to further utilize the industrial solid waste discharged from the coal chemical industrial park - coal gasification slag, the carbon in the coal gasification slag is extracted, the larger solid particles and ash are separated, and the carbon-containing material (carbon powder) is obtained. It is convenient to prepare various building materials (such as concrete admixtures, concrete fine aggregate), mesoporous materials, silicon fertilizers and soil conditioner materials from the silicon and aluminum components after carbon extraction. A device for extracting carbon from coal gasification slag is proposed. Utility Model Content

[0037] The specific implementation process is as follows:

[0038] During use, the coal gasification slag is poured into the feed port 204, and the control device is used to control the operation of the crushing motor 201, so that the operation of the crushing motor 201 drives the active crushing roller 202 to rotate, and the active crushing roller 202 drives the driven crushing roller 203 to rotate, so that the active crushing roller 202 and the driven crushing roller 203 crush the coal gasification slag, so that the materials of different sizes are crushed into smaller and powdery materials, and the crushed coal gasification slag materials fall onto the surface of the screening plate 302, so that the control device controls the operation of the eccentric motor 301, so that the operation of the eccentric motor 301 drives the screening plate 302 to rotate eccentrically.
