Embodiment Construction

[0030] The application will be described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific embodiments are only used to further illustrate the application, and should not be construed as limiting the protection scope of the application. Those skilled in the art can The above application content makes some non-essential improvements and adjustments to this application.

[0031] like Figure 7 As shown, the absorption refrigeration system in this embodiment includes an evaporator 300, a condenser 200, a generator 100, a solution pump 400 and a new type of absorber. The generator 100 uses waste heat medium as a heating source, and the new type of absorber uses a The waste heat medium discharged from the outlet of the heat source of the generator 100 is used as a heat source for preheating the rich liquid discharged from the new absorber. On the one hand, it can improve the utilization rate of the waste ...

Abstract

The invention relates to a novel absorber and an absorption refrigeration system thereof, belonging to the technical field of absorption refrigeration. The first-layer spraying device is fixed on the top of the shell, and the first-layer spraying device is arranged above the upper-layer tube bundle, and the second spraying device is arranged in the U-shaped groove of the side U-shaped tube bundle. There are two groups of main air intake pipes on the side, and each group of main air intake pipes is provided with linearly arranged air distribution pipes between the casing and the pipe box. The circulating water at the circulating water outlet on the tank exchanges heat with the lean liquid entering the shell to pre-cool the lean liquid. Compared with the absorber structure of the prior art, the present invention adopts the double-layer spraying + multiple air intake methods, so that the absorption efficiency of the absorber is increased by about 95%.

Description

technical field [0001] The invention belongs to the technical field of absorption refrigeration, and particularly relates to a novel absorber and an absorption refrigeration system thereof. Background technique [0002] At present, the absorber in the absorption refrigeration unit mostly adopts the horizontal falling film absorber, which is similar to the shell and tube heat exchanger, such as Figure 1-2 As shown, a tube bundle is arranged in the casing, and the circulating water passes through the tubes. There is a layer of spraying device above the tube bundle. The lean liquid enters the spraying device from the top, and is sprayed by the spraying device in an atomized form, and sprayed on the outer wall of the tube bundle to form a film and flow down one by one, so that all the surfaces of the tubes are filled with liquid. surrounded by membrane. The gaseous refrigerant enters from the upper part of the shell, contacts with the liquid film outside the tube wall and is a...
