Description

Technical Field

[0001] This application relates to a deep dehydration device for fine residue from coal-to-methanol gasification. Background Technology

[0002] Gasification slag is a solid waste generated from the coal gasification process. Its main components are coal ash, some unconverted carbon, and heavy metals that can easily pollute soil, water, and the atmosphere. Due to the ash content of the raw coal and the system load, the moisture content of the gasification slag exceeds 60%, resulting in significant water waste. Furthermore, it presents challenges such as difficult slag disposal and high transportation costs. Therefore, dehydration of the coal-to-methanol gasification slag is necessary.

[0003] Existing technology disclosure number CN217120558U discloses a coal processing dewatering device for mining, relating to the field of coal processing technology. It includes a housing, with a support member fixedly connected to the bottom surface of the housing, a feed cylinder fixedly connected to the upper surface of the housing, a first motor fixedly connected to the right side of the housing, a first rotating shaft fixedly connected to the output end of the first motor, and a first spiral blade fixedly connected to the outer surface of the first rotating shaft. A dewatering mechanism, including a dewatering barrel, is provided inside the housing. Through the cooperation of the feed cylinder, the first motor, the first rotating shaft, the first spiral blade, the dewatering mechanism, and the cleaning mechanism, coal to be dewatered is easily added to the dewatering barrel using the feed cylinder, the first motor, the first rotating shaft, and the first spiral blade. The dewatering mechanism performs rotary dewatering on the coal, and the cleaning mechanism facilitates the collection and cleaning of coal slag and washing water.

[0004] Gasification slag dewatering devices are generally sealed. After dewatering, some gasification slag will adhere to the internal structure of the device, making it difficult to clean the inside of the device, such as the dewatering device mentioned above. Moreover, rotary dewatering can only remove the moisture on the surface of the slag, while the moisture inside the slag will still be retained, resulting in a low dewatering effect.

[0005] Therefore, it is desirable to provide a deep dehydration device for coal-to-methanol gasification fine residue. Utility Model Content
