Abstract

PURPOSE:To disperse always uniformly a diluted liquid injected out of a diluted liquid conduit toward a thermal transmitting pipe by a method wherein the diluted liquid injected from the diluted liquid conduit is received by a baffle plate and a flow regulating plate is arranged so as to cause the diluted liquid to be uniformly dispersed into the thermal transmitting pipe. CONSTITUTION:Solution absorbing refrigerant within an absorption device 1 becomes a diluted solution. The solution is guided into a high temperature regenerator 4 through a diluted liquid conduit 3 through a solution pump 2 and then injected out of an opening of the diluted liquid conduit 3. The injected diluted liquid is received by a baffle plate 5 and accumulated on a flow regulat ing plate 6. The flow regulating plate 6 is formed with holes coinciding with a row of a thermal transmitting pipe 7, the accumulated diluted solution passes through the holes and the solution is uniformly dispersed onto the thermal transmitting pipe 7 where steam of heat source passes and then the solution is heated and condensed.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a regenerator for an absorption refrigerator.

[Conventional technology]

Conventionally, in regenerators in which high-temperature steam, which serves as a heat source, passes through the heat transfer tube and heats and concentrates the dilute liquid outside the heat transfer tube, the dilute liquid is introduced through the dilute liquid conduit and is ejected from the top into the heat transfer tube. A baffle plate is installed between the dilute liquid conduit opening and the heat transfer tube to adjust the distribution of the dilute liquid spouted from the dilute liquid conduit to the heat transfer tube, but simply installing a baffle plate is not enough. The intermittent presence of dry and wet areas in high-temperature heat transfer tubes may lead to a decline in heat transfer performance, and the high concentration and high temperature may lead to a negative corrosive environment for heat transfer tubes.

[Problem to be solved by the invention]

With the above conventional technology, the diluted liquid cannot be uniformly spread over the heat transfer tube, and the heat transfer tube has intermittently dry areas and wet areas, which leads to a decrease in heat transfer performance. However, there was a problem that the high concentration and high temperature created a corrosive environment for the heat exchanger tubes.

SUMMARY OF THE INVENTION An object of the present invention is to provide a regenerator for an absorption refrigerating machine that always evenly spreads diluted liquid ejected from a diluted liquid conduit to heat transfer tubes.

[Means to solve the problem]

In order to achieve the above purpose, a baffle plate catches the diluted liquid spouted from the diluted liquid conduit, and a rectifying plate is installed so that the diluted liquid is evenly distributed over the heat transfer tube, and the diluted liquid passes through the rectifying plate and is evenly distributed. It is designed to be sprayed onto heat transfer tubes.

[Effect]

By uniformly distributing the diluted liquid over the heat transfer tube, the concentration and temperature non-uniformity on the heat transfer tube surface is reduced, which reduces the loss of heat transfer area, and also reduces the loss of heat transfer area on the heat transfer tube surface, which is not good for heat transfer tubes due to the corrosive environment. It is possible to change the situation of high temperature and high concentration in a positive direction.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

The solution that has absorbed the refrigerant in the absorber 1 becomes a diluted solution, which is introduced into the high temperature regenerator 4 through the diluted liquid conduit 3 via the solution pump 2, and is ejected from the opening of the diluted liquid conduit 3. The ejected dilute solution is stopped by the baffle plate 5 and the baffle plate 5
and accumulates on the rectifying plate 6. The baffle plate 6 has holes that match the arrangement of the heat transfer tubes 7, and the accumulated dilute solution passes through the holes and is evenly spread onto the heat transfer tubes 7 through which the heat source steam passes, and is heated and concentrated. be done. In addition, 8 is heat source steam, 9
is a drain.

According to this embodiment, the diluted liquid spouted from the diluted liquid conduit can always be evenly distributed over the heat transfer tubes.

〔Effect of the invention〕

According to the present invention, it is possible to obtain a regenerator for an absorption refrigerator that can evenly distribute diluted liquid to heat transfer tubes.
