Cyclone separator having central cylinder made of non-metal refractory material

A cyclone separator, comprising:

• a housing that forms a separation chamber, an inlet of the separation chamber being provided on a side wall of the housing, an outlet of the separation chamber being provided on a top end of the housing;
• a central cylinder located inside the housing, the central cylinder dividing the separation chamber into an outer separation chamber and an inner separation chamber, the outer separation chamber being in communication with the inlet, the inner separation chamber being in communication with the outlet;
• and
• a support structure located inside the housing for supporting the central cylinder, the support structure being a hollowed-out upwardly-arched structure radially provided on an inner wall of the separation chamber, an arch face of the support structure being connected to a lower end of the central cylinder,
• wherein:
• the central cylinder is made of a non-metal refractory material, resistant to wearing and deformation under high temperature,
• an upper end of the central cylinder is connected to an inner side of the top end of the housing by continuous pouring or masonry,
• the lower end of the central cylinder is connected to the support structure by continuous pouring or masonry, and
• the support structure is connected to the inner wall of the separation chamber by continuous pouring or masonry.
