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 cannot be interpreted as limiting the protection scope of the application. 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 absorber, the generator 100 uses waste heat medium as a heating source, and the new absorber utilizes the generated The waste heat medium discharged from the heat source outlet of the generator 100 is used as the heat source for preheating the rich liquid discharged from the new absorber. On the one hand, it can improve the utilization rate of waste heat, and on the other hand, it can redu...

Abstract

The invention relates to a novel absorber and an absorption type refrigeration system thereof, and belongs to the technical field of absorption type refrigeration. The novel absorber comprises a pipe box and a shell, a U-shaped pipe bundle is arranged in the shell, an upper layer spraying device and a lower layer spraying device are arranged in the shell, and the first layer spraying device is fixed to the top end of the shell and is arranged above an upper layer pipe bundle. The second spraying device is arranged in a U-shaped groove of a side U-shaped pipe bundle, two main air inlet pipes are arranged on the two sides of the shell, linearly-arranged branch air pipes are arranged between each main air inlet pipe and the shell, and the pipe box is provided with a circulating water inlet and a circulating water outlet which are connected with the pipe bundle. Circulating water of the circulating water outlet in the pipe box is utilized to exchange heat with barren liquor entering the shell so as to precool the barren liquor. Compared with an absorber structure in the prior art, the double-layer spraying and multi-position air inlet mode is adopted, so that the absorption efficiency of the absorber is improved to be about 95%.

Description

technical field [0001] The invention belongs to the technical field of absorption refrigeration, and in particular 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, tube bundles are arranged in the casing, and 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 in an atomized form by the spraying device, sprayed on the outer wall of the tube bundle, forming a thin film and flowing down row by row, so that all the tubes are covered 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 absorbed by th...
