Abstract

The invention relates to a multi-tube type bubble pump device. The multi-tube type bubble pump device is provided with a low-level reservoir and a high-level reservoir. A liquid supplementing port is formed in the side face close to the bottom of the low-level reservoir, a liquid drainage port is formed in the side face close to the bottom of the high-level reservoir, an air exhaust port is formed in the side face close to the top of the high-level reservoir, the low-level reservoir is communicated with the high-level reservoir through multiple vertical lifting tubes, and a bubble generating device is arranged at the bottom of the low-level reservoir. The liquid lifting device is simple and compact in structure and high in lifting efficiency, bubbles are generated uniformly and stably, and the utilization rate of the bubbles and the lifting amount of a liquid lifting pump are increased by increasing the number of the lifting tubes and reasonably distributing air.

Description

technical field

[0001] The invention relates to a multi-pipe air bubble pump device, in particular to a vertical riser pipe air bubble pump device. Background technique

[0002] In the single-pressure absorption refrigeration system, the working state of the bubble pump is a gas-liquid two-phase flow state, and the mixed working medium in the bubble pump is heated by inputting energy to the heating tube in the low-level liquid reservoir, so that the easily vaporized components form bubbles Separated from the mixed working medium; the formed bubbles rise in the vertical riser and push the liquid mixed working medium to flow to the upper gas-liquid separator; at the same time, the density of the gas-liquid two-phase mixture in the vertical riser is higher than that of the gas-liquid two-phase mixture The density of the liquid in the container that delivers the mixed working fluid to the bubble pump is low, so there is a certain pressure difference between them to form an u...
