The invention discloses a gas-solid phase feed distributor comprising a casing and a feeding mechanism arranged in the casing, wherein a feed opening communicated with the feeding mechanism is arranged on the casing. The gas-solid phase feed distributor is characterized in that the feeding mechanism comprises a sleeve which is coaxial with the casing, is arranged inside the casing and is provided with a first part, a third part and a second part; the distance between the outer wall of the first part and the inner wall of the casing is smaller than the distance between the outer wall of the third part and the inner wall of the casing; an annular gas-solid phase fluid channel is formed between the sleeve and the casing; the feeding mechanism further comprises a base plate, a plurality of deflectors, a plurality of spoilers and an emptying port; the bottom end of the sleeve is connected with the casing in a sealing manner by using the base plate; the deflectors are uniformly and symmetrically arranged on the base plate at intervals; the spoilers are spirally arranged between the inner wall of the casing and the outer wall of the first part of the sleeve; and the emptying port is arranged on the base plate and is used for draining liquid in a container during a hydraulic test. Compared with the prior art, the gas-solid phase feed distributor can be used for a high-temperature and high-pressure fly ash filter and has the advantages of not occupying the effective space of the casing, not influencing the falling of fly ash falling off a filter element, not giving rise to the secondary dust fly and the like.
