Drop-leaching device and lithium bromide unit

Abstract

The embodiment of the invention discloses a drop-leaching device. The drop-leaching device comprises a top-layer drop-leaching liquid distribution tank, a bottom-layer drop-leaching liquid distribution tank and at least one middle-layer drop-leaching liquid distribution tank arranged between the top-layer drop-leaching liquid distribution tank and the bottom-layer drop-leaching liquid distribution tank. First positioning lugs are arranged at the top of the middle-layer drop-leaching liquid distribution tank located on the top layer, and positioning space for positioning the top-layer drop-leaching liquid distribution tank is formed between the first positioning lugs on the same middle-layer drop-leaching liquid distribution tank. The top-layer drop-leaching liquid distribution tank and the middle-layer drop-leaching liquid distribution tanks can be conveniently positioned, the positioning difficulty is lowered, and positioning reliability is improved. The positioning lugs have the reinforcing effect, the thickness of a steel plate can be effectively reduced, the weight of the drop-leaching device is reduced, and connecting strength is enhanced. The invention further discloses a lithium bromide unit.

Description

technical field [0001] The invention relates to the technical field of lithium bromide unit, more specifically, to a dripping device and a lithium bromide unit. Background technique [0002] Lithium bromide units include lithium bromide absorption refrigerators and lithium bromide direct-fired refrigerators. In the lithium bromide absorption unit, water is used as the refrigerant and lithium bromide is used as the absorbent. In order to achieve sufficient heat exchange between fluids and save the amount of solution, liquid dripping or spraying technology is often used to achieve uniform liquid distribution. [0003] At present, the liquid distribution structures widely used include spray liquid distribution, plate-sprinkling liquid distribution, upper-hole spray distribution liquid and multi-layer dripping liquid distribution. Among them, although the use of spray liquid distribution can ensure the uniformity of liquid distribution, the outlet of the nozzle is prone to bloc...

AI Technical Summary

Problems solved by technology

Among them, although the use of spray liquid distribution can ensure the uniformity of liquid distribution, the outlet of the nozzle is prone to blockage; the fluid circulation required for the liquid distribution of the spray plate is relatively large, and the dripping small holes are also prone to blockage; The drip cloth technology effectively prevents the problem of drip hole blockage, but at the end of the drip pipe due to the loss of pipeline resistance along the way, the amount of drip cloth is prone to unevenness; multi-layer drip cloth is used The liquid distribution method is uniform and the drip device is not easy to block through the upper hole of the liquid distribution pipe. However, due to the layered arrangement of the device, it is difficult to locate between layers, resulting in ineffective positioning and poor reliability.
