The upper layer point being arranged concentrically respectively with each heat exchanger tube is distributed on the distribution grid of upper layer for the conical distribution plate distribution hole different to position
Multiple groups lower layer distribution grid distribution hole is distributed on the distribution grid of downside in fabric swatch distribution hole, and every group of lower layer's distribution grid distribution hole includes
At least three along the corresponding circumferentially spaced lower layer's distribution grid distribution hole of upper layer distribution grid distribution hole.
The diameter of upper layer distribution grid distribution hole is less than the internal diameter of corresponding heat exchanger tube.
The upper perforated plate upper end is provided with multiple connecting screws being vertically arranged, and sets on upper layer distribution grid, lower layer's distribution grid
It is equipped with screw rod perforation corresponding with each connecting screw, upper layer distribution grid, lower layer's distribution grid are by spinning on connecting screw
Attaching nut is fixed on connecting screw.
The outer rim of upper layer distribution grid is fixed with annular baffle ring, and the outer rim of lower layer's distribution grid is fixed with lower annular baffle ring.
The height of upper annular baffle ring is higher than the height of lower annular baffle ring.
The utility model has the following beneficial effects: material enters in the intracorporal conical distribution plate of tank through material inlet when work
In chamber, each position of upper layer distribution grid is uniformly then flowed to along corresponding conical distribution plate distribution hole, and be distributed along upper layer
Plate distribution hole flows to lower layer's distribution grid, and each upper layer distribution grid distribution hole flows to the material on lower layer's distribution grid and then dissipates around
It opens and flows in each lower layer's distribution grid distribution hole of each group lower layer distribution grid distribution hole, due to every group of lower layer's distribution grid distribution hole edge
The circumferentially-spaced arrangement of corresponding heat exchanger tube, therefore the logistics through every group of lower layer's distribution grid distribution hole can flow in each heat exchanger tube
Wall, and flow downward along the inner wall of heat exchanger tube, the tube wall contact of material and heat exchanger tube sufficiently, realizes good heat transfer effect.
