Abstract

A liquid distribution device used for an absorber comprises a drop-leaching device, a liquid guide device and a liquid distribution plate. The drop-leaching device is installed in a barrel of the absorber and located above an upper layer heat exchange pipe and communicates with a concentrated solution storage device. The liquid guide device is installed below the upper layer heat exchange pipe, the outer side of the liquid guide device is slightly higher than the inner side in the inclined direction, and the liquid guide device is fixed to the barrel or a water blocking set. The inner side of the liquid guide device is fixedly connected with the liquid distribution plate. Lower spray holes are evenly distributed on the liquid distribution plate and correspond to row tubes of a lower layer heat exchanger in number and position one to one, wherein the lower heat exchanger is arranged below the lower spray holes. The interception device used for the absorber is simple in structure and convenient to use, concentrated solution drops which are blown away are collected through the liquid guide device, the waste quantity of concentrated solutions is decreased, the concentrated solution drops then drip on and sprinkle over a lower layer heat exchange pipe through the liquid distribution plate, the utilization rate of the concentrated solutions is increased, and the coefficient of performance (COP) of absorption chiller-heaters is accordingly increased.

Description

technical field [0001] The invention relates to a liquid distribution device, in particular to a liquid distribution device for an absorber and an absorber containing the liquid distribution device. Background technique [0002] Absorption cooling and heating units rely on the evaporation and cooling of the refrigerant water in the evaporator. The refrigerant water becomes water vapor and blows to the absorber through the water blocking group, and the water vapor is absorbed by the concentrated lithium bromide solution in the absorber, and the released heat Passed to cooling water, released to atmosphere. The concentrated solution dripped by the dripping device in the absorber is inevitably blown by the water vapor to the cylinder, the water retaining group or the heat exchange tube, so that the solution flows directly to the bottom of the unit, resulting in the waste of the concentrated solution and reducing the water vapor Absorption and inhibition of the evaporation of t...
