Showering spray type generator with exhauster

Abstract

The invention relates to an atmospheric generator which is used in a steam-type lithium bromide absorptive water chilling unit and is provided with an exhaust device, which comprises a steam inlet pipe (1), an inlet end cover (2), a tube plate (3), a heat exchange tube bundle (4), a dilute solution distribution device (5), an outlet end cover (6) and a condensate water outlet pipe (7), wherein, the outlet end cover (6) is provided with an exhaust device (8); the exhaust device (8) consists of a plurality of inner exhaust branch pipes (8.1), an inner exhaust pipe (8.2) and an outer exhaust pipe (8.3), wherein, the inner exhaust branch pipes (8.1) are vertically connected with the lower part of the inner exhaust pipe (8.2 ); a plurality of air vents (8.1.1) are arranged vertically in the opposition of the steam outlet of each inner exhaust branch pipe (8.1); the bottom part of each inner exhaust branch pipe (8.1) is provided with a portiforium (8.1.2) used to exhaust liquid and gas; the lower end of the outer exhaust pipe (8.3) is communicated with the inner exhaust pipe (8.2), while the upper end extends out of the outlet end cover (6). The invention is capable of exhausting foul gases in multi-component gases, thus ensuring the heat exchange effect of the atmospheric generator and improving the performance and stability of the unit.

Description

(1) Technical field [0001] The invention relates to a shower type generator used for a steam type lithium bromide absorption chiller. It belongs to the technical field of refrigeration equipment. (2) Background technology [0002] The previous steam-type lithium bromide absorption chiller shower generator is shown in Figure 1. The heating steam enters the inlet end cover 2 through the steam inlet pipe 1 and is distributed to the tube side of the heat exchange tube bundle 4. The heating shell side is evenly distributed to the dilute solution produced by the falling film outside the heat exchange tube through the dilute solution distribution device 5, and the steam condenses Become water, discharge through condensed water outlet pipe 7 after outlet end cover 6 merges. The above structural form is suitable for the heating source being a single component such as pure water vapor. At present, with the continuous development of energy-saving technology, lithium bromide absorpti...
