Problems solved by technology

[0004] However, with the change of system working fluid, solution concentration, heating power, submersion ratio and other parameters, the pipe diameter with the best lifting efficiency of the bubble pump or the optimized pipeline combination will change immediately. Constructing the entire system is a complex, tedious, and costly process

Embodiment 1

[0035] The riser combination device is a set of devices connected between the bubble generator and the gas-liquid separator. figure 2 An example of adapting a round tube size (outer diameter 19mm) is given. The outer diameter of the part is fixed, and the size of the inner diameter is determined by the outer diameter of the required round tube. Adjust the inner diameter to adapt to different outer diameters. Round tube, the inside of the part is composed of two cylinders with an outer diameter of 22mm and a height of 25mm and a cylinder with an outer diameter of 20mm and a height of 5mm. A gap with a thickness of 1mm is formed between the two for filling and sealing Materials (such as water-swellable water-stop rings resistant to high heat). The upper part of the part is punched, and the special tool is designed to facilitate installation and disassembly. Different round pipe joints are combined with round pipes of different diameters image 3 Tube assembly shown. In the s...

Abstract

The invention discloses a coordinated controllable bubble pump lifting pipe device. The lifting pipe device comprises a universal joint, a connector and a pipe assembly, wherein the universal joint isused for being connected with a bubble generator or a gas-liquid separator, the outer diameter of the connector connected with the universal joint is fixed and unchanged, and the size of the inner diameter is matched with the size of the outer diameter of the pipe assembly; and the outer sidewall of the pipe assembly is mounted in the inner sidewall of the connector. With the coordinated controllable bubble pump lifting pipe device, free combination of different types of lifting pipes under different working conditions and variable parameters is realized, two-phase flow patterns in the lifting pipes are controlled to be kept at the highest lifting efficiency through coordinated control of the lifting pipe device, a bubble pump system is optimized, and thus the utilization rate of waste heat energy of ships is accordingly improved.

Description

technical field [0001] The invention relates to the technical field of fluid machinery, in particular to a coordinated and controllable air bubble pump riser device. Background technique [0002] At present, more than 90% of the global trade is transported by ships, which makes the shipping industry the weathervane of the global economy. With the continuous deepening and practice of the concept of "green ocean", the research on energy saving, emission reduction and energy recovery of ships is becoming more and more important. practical significance. The recovery and utilization of ship waste heat is an effective measure for ship energy saving and emission reduction. Bubble pump technology is driven by ship waste heat. It is widely used in the research field of ship absorption refrigeration system and can replace traditional mechanical pumps. It is not only safe and environmentally friendly It is non-polluting, and can save 30% of electric energy consumption and increase the...
