Embodiment Construction

[0020] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail, but present embodiment is not intended to limit the present invention, and every adopt similar structure of the present invention and similar change thereof, all should be included in the protection scope of the present invention.

[0021] A bubble pump with a bubble trap, such as figure 1 As shown, it includes a riser 4, a bubble collection device 3 and a low-level liquid reservoir 1. The lower part of the bubble pump riser 4 is connected to the low-level liquid reservoir 1, and the low-level liquid reservoir 1 is connected to the generator. The low-level liquid reservoir 1 A heat exchanger 2 is arranged inside, and the heat exchanger 2 is connected to an external heat source. Above the heat exchanger 2, a bubble collecting device 3 is connected at a position perpendicular to the heat exchanger. The upper part of the low-level liquid reservoir 1 has a fig...

Abstract

The invention relates to a gas bubble pump with a gas bubble collecting device. The gas bubble pump is characterized in that the lower part of a lifting pipe of the gas bubble pump is connected with a low-level liquid storage device; the low-level liquid storage device is connected with a generator; a heat exchanger is arranged in the low-level liquid storage device and is connected with an outside heat source; the position above and perpendicular to the heat exchanger is connected with a gas bubble collecting device; the upper part of the low-level liquid storage device forms a horn-shaped structure; the gas bubble collecting device is fixedly connected with the inner wall of the low-level liquid storage device through three rib plates; the lower part of the low-level liquid storage device forms a horn-shaped structure; the upper part is connected with an exit pipe opening; and the horn-shaped structure at the upper part of the low-liquid storage device is parallel with the horn-shaped structure at the lower part of the low-liquid storage device. The invention has simple structure, the amount of the lifted liquid in the lifting pipe in unit time is maximum, and the efficiency of the gas bubble pump is enhanced. The low-grade unstable heat source can be directly utilized, the manufacture cost is low, and the efficiency is high.

Description

technical field [0001] The invention relates to single-pressure absorption refrigeration technology and equipment, in particular to a bubble pump with a bubble collection device. Background technique [0002] In the single-pressure absorption refrigeration system, the bubble pump works in the state of two-phase flow, and the external heating device at the bottom of the vertical riser generates enough heat flux to evaporate the ammonia in the pump tube and form bubbles; the bubbles rise in the tube and push the liquid At the same time, the density of the gas-liquid mixture in the riser is smaller than that of the liquid in the generator (ie, the low reservoir), so it can generate enough buoyancy to lift the two-phase fluid in the tube to a certain level. high. Current research points out that when the two-phase flow in the riser is in a slug flow or transitions from a slug flow to a block flow, the delivery efficiency of the bubble pump is the highest, that is, the amount of...
