Problems solved by technology

[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

[0043] The specific embodiment of the comprehensive utilization of coal gangue pyrolysis gasification of the present invention is mainly introduced in detail below.

[0044] Part 1 Particle Size Control of Coal Gangue

[0045] 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.

[0046] Part II Humidity Control and Dehydration of Coal Gangue

[0047] Such as figure 1 , figure 2 Shown: the humidity control and dehydration device 1 for hot waste gas entering the furnace coal gangue, including a housing 11, a water vapor exhaust exporter 12, a waste gas heat exchange dehydrator 13, and a feeding bin 14; Coal gangue granules are silos 111 for humidity control and drying. The relatively closed top of the silo 1...

Abstract

The invention provides a continuous thermal cycle coal gangue pyrolysis gasification humidifying and tail gas purifying device which comprises a coal gangue pyrolysis gasification device, a crude gas guiding device, a furnace coal gangue hot waste gas humidifying dehydrating device, and a tail gas showering purifier, wherein the coal gangue pyrolysis gasification device consists of a coal gangue pyrolysis device and a water gas reaction device; the coal gangue pyrolysis device consists of a pyrolysis gasification chamber, an external gas heating device and an internal gas heating device; the water gas reaction device consists of a material cooling device and a steam generation device; the furnace coal gangue hot waste gas humidifying dehydrating device consists of a water vapor discharge guider and a waste gas heat exchange dehydrator; the tail gas showering purifier consists of a purifying cylinder, an atomized sprinkler, a stainless steel filter screen mesh layer, a tail gas deflector, a water tank, an impounding reservoir and a spray water pump; and raw gas guided from the raw gas guiding device is purified and then burnt, the burnt waste gas is sent to the waste gas heat exchange dehydrator to dehydrate coal gangue aggregates in the furnace, and the dehydrated waste gas is purified and discharged by using the tail gas showering purifier.

Description

technical field [0001] The invention relates to coal gangue pyrolysis gasification technology, in particular to a thermal cycle continuous coal gangue pyrolysis gasification humidity control and tail gas purification 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 (comp...
