The invention discloses a loose component in a GSP gasification pulverized coal conveying system. The loose component comprises a metal shell and a multi-layer sintering metal net filter core, wherein the metal shell is provided with a connecting disk and a connecting pipe; the connecting disk and the connecting pipe have an integrated structure; the first end of the connecting disk is connected with a loose gas pipeline; the second end of the connecting disk is connected with the first end of the connecting pipe; the second end of the connecting pipe is connected with pulverized coal conveying equipment; the multi-layer sintering metal net filter core is welded in the second end of the of the connecting pipe and has a cylindrical structure; the upper surface of the multi-layer sintering metal net filter core is flush with the pipe orifice of the second end of the connecting pipe; and the lower surface of the multi-layer sintering metal net filter core extends into the connecting pipe. The loose component radically solves the problem that a synthetic resin bonding sand material cannot bear high fatigue stress and the loose component is damaged in a short time, and improves the operating stability of the pulverized coal conveying system.
