Abstract

PURPOSE:To make a title device compact by disposing a fluid tube communicating with a fluid wall to be heated in a cyrindrical structure with its exhaust part on its upper part so as to cross the cylindrical structure slantingly longitudinally, mounting a fin on the fluid tube and disposing a burner below the cylindrical structure. CONSTITUTION:Once combustion is started in a burner 6, combustion gas is raised in its temperature heating a fluid wall 2 to be heated and a fluid tube 4. The fluid tubes 4 are disposed to cross each other slantingly longitudinally, so heat exchanger is with a cross type to greatly improve heating efficiency. More specifically, since the fluid tubes 4 are disposed to cross each other slantingly longitudinally, a heat transfer area is increased and the rising combustion gas becomes turbulent owing to the fluid tubes to sharply improve the heating efficiency. When such fluid tubes are crossed slantingly at the upper portion, the combustion gas is not cooled rapidly in a space at the lower portion of the device and exchanges heat in a completely burned state. Additionally, since the fluid tubes 4 are constructed slantingly, bubbles in the tube are easily released to improve the heating efficiency and hence make the device more compact.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a vertical high temperature regeneration device for a gas absorption chiller/heater.

(Prior art and problems) As shown in Figure 1, conventional high-temperature regeneration devices for gas absorption chiller/heaters are usually furnace-tube-type devices that have separate furnace tube sections and smoke tube sections. Ta. This device exchanges heat by flowing combustion gas from a plasto burner through a smoke tube inside a dilute lithium bromide solution reservoir, boils the lithium bromide solution, and generates a concentrated solution and refrigerant vapor. Since such conventional devices are horizontally long, they require a large installation space.
In addition to occupying a large volume, it holds a large amount of solution and has slow load response. Moreover, since it is a horizontally elongated type, a plasto burner with a long flame length must be used, and such a burner has a high noise level, requires periodic inspection, and is costly. Furthermore, since the furnace cylinder section and the smoke tube section, that is, the combustion chamber and the heat exchange section, are constructed separately, it has been difficult to improve the compactness of the conventional apparatus. Through repeated trial and error, the inventors of the present invention learned that there were difficulties in improving conventional devices, and arrived at the present invention by thinking from a completely different angle.

It is a cylindrical body composed of a liquid wall 2, and this cylindrical body 1 has an exhaust port 3 at the upper end, and inside thereof is a liquid pipe 4 communicating with the heated liquid wall 2 as described in f. The liquid pipe 4 is arranged so as to cross the subject in the vertical direction, and a fin 5 is attached to the liquid pipe 4.
A bar 6 is installed at the lower end of the cylindrical body 1. In the device described in item 2, the liquid pipes 4 described in item 1 are constructed so as to intersect diagonally at the upper position of the liquid pipes.

(Function) When combustion starts in the burner 6, the combustion gas rises while heating the heated liquid wall 2 and the liquid pipe 4.

In this case, since the liquid pipes 4 are piped so as to intersect with each other in the vertical direction, the heat exchange is of the orthogonal type, and the heating efficiency is greatly improved. Since the pipes are laid across the pipes, the heat transfer area becomes large, and the liquid pipes create a turbulent flow of the combustion gas, which dramatically improves the heating efficiency. When such liquid pipes are diagonally crossed at their upper positions, the combustion gas is not rapidly cooled down in the space at the lower position, and as a result, heat exchange as described above can be performed in a complete combustion state. There are advantages. In addition, since the liquid pipe 4 is used as a subject, there is an advantage that air inside the pipe can be easily removed from the pipe.

In this way, the combustion chamber and the heat exchange section are integrated, and as described above, the heating efficiency is improved, so that the -layer can be made more compact. In fact, compared to conventional equipment, the installation area is 70% to 80% smaller, and the occupied volume is reduced by 70% to 80%.
It was possible to configure the size by 20% to 30%. Moreover, by making the apparatus itself vertical, a commonly used short flame burner can be used, and maintenance is easy and extremely low noise can be achieved. Furthermore, the vertically elongated configuration can reduce the installation area.

(Effects of the Invention) As described above, the present invention has a unique configuration for the playback device, thereby making it possible to reduce the size of the playback device, and at the same time,
In addition to being able to provide a low-cost playback device that generates little noise and requires almost no maintenance, it also has the great advantage of reducing the installation area.
