Coal gangue treatment system

The utility model provides a coal gangue treatment system, which comprises a melting device, a combustion device, a gas supply device, a gas supply device, a gas supply device, a gas supply device and a gas supply device, and is characterized in that the melting device is provided with a melting cavity for accommodating coal gangue; and the Brown gas generator is connected with the combustion device, the Brown gas generator is used for providing Brown gas for the combustion device, and the ignited Brown gas ignites the coal gangue in the melting cavity. According to the technical scheme, the combustion device is arranged, Brown gas can be introduced into the melting device for combustion supporting, the Brown gas is high in combustion speed and temperature rising speed and can rapidly reach the ignition point of coal gangue, and therefore cracking and combustion of organic matter in the coal gangue are accelerated, complete combustion of the coal gangue is achieved, and the coal gangue combustion efficiency i
