Adjustable inner-cooling type falling film absorption experimental device

Abstract

The invention discloses an adjustable inner-cooling type falling film absorption experimental device. The adjustable inner-cooling type falling film absorption experimental device is composed of an upper end cover, a lower end cover, a cylinder body and a falling film implement. The upper end cover, the lower end cover and the cylinder body are all in bolt connection to form an absorption bin. The falling film implement is placed in the absorption bin. The falling film implement is composed of a liquid overflow groove, a support, a liquid absorption layer, a falling film plate, adjusting rods, a water collecting pipe, a water distributing pipe, capillary tubes and a gradienter. According to the experimental device, the falling film implement can be horizontally adjusted through the thread connection of the four corners of the support, and the inclination, caused by installation or an uneven bottom contact surface, of the falling film implement is avoided; the uniformity of a liquid film in the falling film absorption process is ensured by arranging the gradienter to monitor whether the falling film plate is horizontal; a stable temperature field in the falling film absorption process is ensured by welding a same-course type cooling water pipeline on the lower surface of the falling film plate; the stability of liquid flow and the uniformity of the liquid film are ensured by bonding the liquid absorption layer with the upper surface of the falling film plate.

Description

technical field [0001] The invention belongs to the field of machinery, and relates to an absorption experiment device, in particular to an adjustable internal cooling falling film absorption experiment device. Background technique [0002] At present, under the dual pressure of energy supply shortage and environmental pollution, the vapor absorption air conditioning system is considered to be an ideal choice to replace the traditional vapor compression air conditioning system. The steam absorption air-conditioning system can use solar energy, geothermal energy and industrial low-temperature waste heat, expand the utilization of new energy, improve the mode of energy cascade utilization, get rid of the shackles of conventional energy, and play a positive role in sustainable development. [0003] The steam absorption air-conditioning system uses water as the refrigerant and a liquid with strong water absorption as the absorbent. Through the two circulation circuits of the abs...

AI Technical Summary

Problems solved by technology

Most of the existing falling film absorption experimental devices are fixed structures, which do not take into account the problem of tilting of the falling film plate caused by the installation or the uneven contact surface at the bottom, resulting in uneven film distribution

The falling film plate generally adopts a single stainless steel plate, which is easy to cause the liquid flow to converge, and the liquid film is not stable enough.

The falling film process generally adopts natural cooling method, and the cooling effect is poor, which reduces the steam absorption effect
