The condition that horizontal tube falling film heat exchanger operates normally first is that liquid is evenly distributed on every heat exchanger tube with membranaceous,
And the stabilization liquid film of continuous uniform is kept on the entire circumferential and axial direction of every heat exchanger tube.Now widely used drop
Film liquid distributor be cloth liquid structure of orifice plate shape, there are the problem of for orifice flow close from inlet on pipe range direction it is big, from
The remote orifice flow of inlet is small, causes uneven along pipe range direction upper fluid dielectric cloth liquid, substantially reduces changing for heat exchange equipment
Hot property even results in part " dry spot " phenomenon, reduces the service life of heat exchange equipment.
Summary of the invention
In order to solve horizontal falling liquid film liquid distributor on pipe range direction cloth liquid problem of non-uniform and carry out, and it is an object of the present invention to provide
A kind of Novel horizontal falling liquid film liquid distributor, so that spray fluid media (medium) can be uniformly distributed in heat exchange during falling film evaporation
Pipe outer wall face.
The present invention provides a kind of horizontal falling liquid film liquid distributors, including inlet tube and liquid distributor, inlet tube to be connected with liquid distributor,
Inlet tube hollow space is inlet, the sealing of liquid distributor both ends；It is disposed with flow deflector along liquid distributor axis direction below inlet,
Flow deflector is connect with liquid distributor both ends, and there are gaps with liquid distributor shell for flow deflector two sides；Flow deflector down either side is set respectively
It is equipped with the overflow launder along liquid distributor axis direction arrangement, is provided with several cloth along liquid distributor axis direction between two overflow launders
Liquid bath；Overflow hole is had between cloth liquid bath and two overflow launders, cloth liquid bath bottom is provided with liquid distributing hole.
Further, two overflow launders are axially and symmetrically arranged along liquid distributor.
Further, inlet tube and liquid distributor are all cylinder-shaped.
Further, flow deflector is relative to inlet tube axisymmetrical.
Further, the width of overflow launder is greater than the spacing of flow deflector and liquid distributor body clearance.
Further, cloth liquid bath is cone, and radius is gradually reduced from the top to the bottom.
Further, cloth liquid bath is located at two sides overflow launder middle position.
Further, liquid distributing hole is located at cloth liquid bath middle position.
Further, liquid distributing hole aperture is less than or equal to the minimum spacing of the bottom of cloth liquid bath.
Further, overflow hole is rectangular or arc.
Traditional cloth of orifice plate is replaced using flow deflector combination two sides overflow hole slot and intermediate liquid distributing hole slot in the present invention
Liquid mode makes fluid after the inlet of inlet tube inflow liquid distributor, first passes through the overflow launder that flow deflector is evenly distributed to two sides
Interior, after overflow tank liquid reaches full liquid, liquid flows into cloth liquid bath from the overflow hole on both sides, and aggregation forms one in cloth liquid bath
Section fluid column, provides certain static pressure, finally flows out from liquid distributing hole, liquid is made equably to spray the heat exchange to lower section along pipe range direction
Pipe pipe outer wall face, forms the liquid film of stable and uniform.The present invention, which solves horizontal falling liquid film cloth liquid is non-uniform on pipe range direction, to be asked
Topic reduces the probability of liquid distributing hole blocking.
