Bubble pump and application of bubble pump

Abstract

The invention relates to a bubble pump which is composed of a vertical lifting pipe, a high-level liquid storing device, a low-level liquid storing device and a heating device. The heating device is a flat-board type heater or a combination of the flat-board type heater and a fin device for strengthening heat exchange. The flat-board type heater is horizontally arranged in the low-level liquid storing device and adjacent to the bottom of the low-level liquid storing device. The fin device for strengthening heat exchange is installed vertical to the flat-board type heater. The surface of the bottom of the fin device for strengthening heat exchange is tightly connected with the upper surface of the flat-board type heater in a welding mode. The bubble pump is simple and compact in structure, high in heat transmission efficiency, capable of shortening time cost in starting the bubble pump and even and stable in generated bubbles, improves a production rate of the bubbles, reduces heat loss and improves a heat energy utilization rate by enlarging heat transmission area. The bubble pump can be applied to a lithium bromide absorbing type refrigerating device to improve refrigerating capacity of the lithium bromide absorbing type refrigerating device.

Description

technical field [0001] The invention relates to a bubble pump and its application in a lithium bromide absorption refrigeration device. Background technique [0002] At present, the bubble pump is a special form of solution pump, and its structure diagram is as follows: figure 1 As shown, it consists of a vertical riser 4, a high-level liquid reservoir 5, a low-level liquid reservoir 1 and a heating device.
