Description

Technical Field

[0001] The utility model belongs to the field of iron removal from coal raw materials, and particularly relates to an iron removal device for gasification raw coal. Background Art

[0002] Coal is an important raw material in the chemical production process. During the mining, storage, and transportation of raw coal, the iron element content generally increases. Its content and existence form affect the physical and chemical properties of the gasification ash slag of coal, thereby enhancing the slagging performance of the gasification ash slag of coal. In severe cases, it will lead to unsmooth slag discharge and slag blockage in the gasifier, and increased wear of the equipment in the coal gasification section, which has an adverse impact on the stable control of the process parameters in the coal gasification section.

[0003] When the existing iron removal device is used for gasification raw coal, an electromagnet iron removal device is often installed in the gasification coal conveying and coal grinding section to reduce the iron content. However, it is often difficult to achieve the iron removal effect required by the subsequent coal gasification section. The main reasons are as follows: the installation position and installation height of the electromagnet are unreasonable; the large thickness of the coal seam causes the weight of the coal to press and coat the iron, reducing the adsorption capacity of the electromagnet for iron.

[0004] Therefore, aiming at the problem that when the above iron removal device is used for gasification raw coal, the installation position and installation height of its electromagnet are unreasonable, and when the iron removal process is carried out on a relatively thick raw coal seam, the iron filings of the raw coal seam are often wrapped by the relatively thick coal seam, thereby affecting the iron removal effect on the thick raw coal seam. An iron removal device for gasification raw coal is developed. By adding a plow tooth structure with lifting function, a snap-fit assembly structure, an arc-shaped electric scraper structure, and an L-shaped storage structure to the iron removal device, the iron removal effect and efficiency of the device on the thick raw coal seam can be greatly improved, and the convenience of cleaning and collecting the iron filings after iron removal by the device can be enhanced. Summary of the Utility Model
