Zusammenfassung: | The invention discloses a cyclone dust removal device for recycling of high-temperature dust-containing tail gas. The cyclone dust removal device comprises a cylindrical hollow outer cylinder, a hollow inner cylinder, a central air discharging pipe, an inner layer heat exchange pipe, an outer layer heat exchange pipe and a spraying device, wherein the hollow inner cylinder is arranged in the hollow outer cylinder and comprises a first part, a second part and a third part in sequence from top to bottom; the first part is cylindrical, is provided with an air inlet pipe, and forms a first interlayer with the inner wall of the hollow outer cylinder; one end of the air inlet pipe tangentially penetrates through the first part, the other end of the air inlet pipe is communicated with the outside; the second part is conical; an opening is formed in the upper part of the side wall of the second part; the third part is reversely conical; the lower end of the third part props against the hollow outer cylinder so as to form a second interlayer with the second part and the hollow outer cylinder; the central air discharging pipe is arranged in the hollow inner cylinder; the inner layer heat exchange pipe winds along the outer wall of the central air discharging pipe; the lower end of the inner layer heat exchange pipe is communicated with the opening of the second part; the outer layer heat exchange pipe winds along the outer wall of the first part; the lower end of the outer layer heat exchange pipe is communicated with a liquid inlet pipe; the upper end of the outer layer heat exchange pipe is communicated with the upper end of the inner layer heat exchange pipe. The cyclone dust removal device disclosed by the invention has the advantages that both of the dust removal efficient and the heat exchange efficiency are high. |
