Abstract

The invention relates to a liquid distribution device, and particularly relates to a uniform overflow type liquid distributor used for uniformly distributing liquid on a horizontal heat exchange pipe. The liquid distributor comprises a flange, a feeding pipe, a horizontal branch pipe, a spray pipe, a folded-plate type overflow groove, a connecting channel and liquid distributing teeth, wherein the flange is arranged at a feeding opening; one end of the feeding pipe is connected with the flange, and the other end of the feeding pipe is connected with horizontal branch pipe; the spray pipe and the horizontal branch pipe are not in central butt joint, and occurrence of liquid accumulation in the spray pipe can be avoided; liquid in the overflow groove slowly increases by using the spray pipe, so that liquid overflows stably and has small fluctuation.

Description

technical field

[0001] The invention relates to a liquid distribution device, in particular to a uniform overflow liquid distributor for uniformly distributing liquid on a horizontal heat exchange tube. Background technique

[0002] The horizontal tube falling film evaporator has the advantages of high heat transfer efficiency; small temperature difference, especially suitable for evaporation of heat-sensitive solutions; simple equipment, small volume; Food, medicine, chemical industry, sewage treatment, seawater desalination and other industries. One of the key equipment of the horizontal tube falling film evaporator is the liquid distributor (ie, the liquid distributor). The solution passes through the liquid distributor and is evenly distributed on the horizontal heat exchange tubes to form a thin liquid film, which is heated and evaporated. The key to the high heat exchange efficiency of the horizontal tube falling film evaporator is that the liquid distributor can dist...

Embodiment Construction

[0025] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] Such as figure 1 , the flange 1 is set at the entrance, the solution enters the horizontal branch pipe 3 through the feed pipe 2, the horizontal branch pipe 3 is connected with a plurality of spray pipes 4, the spray pipe 4 is arranged on the horizontal branch pipe 3 in parallel, and the center of the spray pipe 4 The line is perpendicular to the horizontal direction of the center line of the horizontal branch pipe 3, the number of the horizontal branch pipe 3 and the spray pipe 4 is determined according to the length of the heat exchange pipe 8 in the evaporator, and the distribution and number of the nozzles 5 are determined according to the number and length of the spray pipe 4 . When the solution is sprayed from the nozzle 5 onto the folded plate overflow tank 6, because the overflow channel 11 has a cer...
