[0002] Coal gangue - the stone selected from raw coal is the waste residue of coal preparation plants, which is not easy to deal with. In China, hundreds of millions of tons of coal gangue cannot be used every year, and it still continues to discharge about 100Mt every year. It not only accumulates and occupies land, but also It can spontaneously combust to pollute the air or cause a fire, causing serious environmental pollution

Embodiment Construction
[0012] The specific embodiment of the comprehensive utilization of coal gangue pyrolysis gasification of the present invention is mainly introduced in detail below.
[0013] Part 1 Particle Size Control of Coal Gangue
[0014] The coal gangue is processed and crushed into a particle size of 0-20 mm, and the crushed coal gangue is dehydrated and dried within this particle size range, and the drying is sufficient and the dehydration efficiency is high, but this does not constitute a limitation on the coal gangue required by the present invention.
[0015] The second part of coal gangue humidity control dehydration
[0016] The waste coal gasification produced by coal gangue high temperature pyrolysis and water gas reaction is recovered and purified, and the hot waste gas generated after combustion of clean coal gas is used for humidity control and dehydration of crushed coal gangue pellets before being put into the furnace.
[0017] In order to keep the environment clean and ti...

According to the control device provided by the invention, the coal gangue pyrolysis gasification technology is under stable control through control on the equipment in a thermal cycle continuous coal gangue pyrolysis gasification comprehensive technology, and the production efficiency is high.
Description
technical field [0001] The invention relates to coal gangue pyrolysis and gasification technology, in particular to a control device for thermal cycle continuous coal gangue pyrolysis and gasification comprehensive device. Background technique [0002] Coal gangue - the stone selected from raw coal is the waste residue of coal preparation plants, which is not easy to deal with. In China, hundreds of millions of tons of coal gangue cannot be used every year, and it still continues to discharge about 100Mt every year. It not only accumulates and occupies land, but also It can spontaneously combust and pollute the air or cause a fire, causing serious environmental pollution. [0003] Due to coalification for hundreds of millions of years, coal gangue contains 20-30% of carbon, oil, and gas substances, of which oil and gas account for 11-15%, and carbon accounts for 7-15%. Pyrolysis and gasification of coal gangue to obtain oil and gas products and 70-80% solid products (compon...
