A cyclone separator is disclosed. The cyclone separator includes a housing that forms a separation chamber, a central cylinder made of a non-metal refractory material and located inside the housing, and a support structure that supports the central cylinder. The separation chamber is divided by the central cylinder into an outer separation chamber and an inner separation chamber. The separation chamber includes an inlet and an outlet that are in communication with the outer and inner separation chambers, respectively. The support structure comprises a hollowed-out upwardly-arched structure that is connected to an inner wall of the separation chamber by continuous pouring or masonry, with an arch face of the support structure being connected to a lower end of the central cylinder to support the central cylinder. The central cylinder is connected to both the housing and the supporting structure by continuous pouring or masonry.

The present disclosure provides an internally self-circulating fluidized bed gasifier and an air distributor therein for generating a stepped constrained wind. The air distributor includes a gas-material mixture through hole and a plurality of vent holes. Each of the vent holes is designed to have a winding path. Due to the winding paths of the vent holes and an arrangement of converging outlets of the vent holes to the gas-material mixture through hole, which is in communication with a furnace chamber, the present disclosure enables a gas entering the furnace chamber to form a stepped constrained wind and effectively prevents solid-phase materials in the furnace chamber from leaking into a gas mixture chamber. The internally self-circulating fluidized bed gasifier can achieve self-circulation combustion gasification for multiple times and a well-controlled gasification temperature, resulting in a high coal gasification efficiency without an ash leakage.
