Nanometer fluid self-dispersion device and lithium bromide absorption refrigeration circulating system

Abstract

The invention discloses a nanometer fluid self-dispersion device, which comprises a shell provided with an inlet and an outlet, and an impeller, a first revolving shaft, a first gear, a second gear, a second revolving shaft, a cutting blade, a sieving chamber and a mixing chamber which are positioned inside the shell. According to the self-dispersion device, agglomerated nanoparticles enter a cutting chamber under the sieving action of a sieve plate, and self-dispersion is performed by using the cutting movement provided by pressure difference, so that nanometer fluid has a self-dispersion function. The invention further discloses a lithium bromide absorption refrigeration circulating system, which comprises a condenser, a generator, an evaporator, an absorber, a heat exchanger, a U-shaped throttling tube, an anti-crystalizing tube, a generator pump, an absorber pump, the self-dispersion device, an evaporator pump, a vacuumizing device, a solution three-way valve, a high-pressure cylinder and a low-pressure cylinder. According to the lithium bromide absorption refrigeration circulating system, the absorber pump or the generator pump is used for driving the self-dispersion device to run, so that the stability and reliability of the lithium bromide absorption refrigeration circulating system are improved.

Description

technical field [0001] The invention relates to a nanometer fluid self-dispersing device and a lithium bromide absorption refrigeration cycle system. Background technique [0002] With the rapid development of nanomaterials science, more and more studies have shown that nanofluids not only have the advantages of improving fluid thermal conductivity, convective heat transfer and boiling heat transfer, but also have the advantages of reducing wall friction resistance and improving optical properties. The enhancement of nanofluids in both heat and mass transfer can be used to enhance the absorption, regeneration, and heat exchange processes in LiBr refrigeration systems. At present, there have been studies at home and abroad to apply nano-materials such as alumina, iron, silicon dioxide, and carbon nanotubes to lithium bromide absorption refrigeration systems, and achieved relatively ideal results. [0003] However, the biggest challenge in the application of nanofluid enginee...
