Abstract
A filter tube for high temperature gas-solid separation is provided that has a first cylinder and a second cylinder coaxially nested in the first cylinder with the first cylinder arranged so that an opening thereof faces upward, a first connection flange provided at a periphery of the opening of the first cylinder, and a circular through-hole provided at a bottom of the first cylinder. The second cylinder is nested in the first cylinder so that an opening of the second cylinder faces downward. The second cylinder has an end at an opening thereof that is hermetically connected to the circular through-hole of the first cylinder. The second cylinder has a bottom, and the bottom of the second cylinder and the opening of the first cylinder are at the same horizontal level. An annular gas passage is formed between the first cylinder and the second cylinder.
