JPH07117318B2 - Vertical high-temperature regenerator for gas absorption chiller / heater - Google Patents

Description

TECHNICAL FIELD The present invention relates to a vertical high temperature regenerator for a gas absorption chiller / heater.

(Prior Art and Problems) As a conventional high-temperature regenerator for a gas absorption chiller-heater, as shown in FIG. 1, a furnace tube smoke tube type apparatus having a furnace tube section and a smoke tube section separately is usually used. It was Such an apparatus is an apparatus for causing heat exchange by flowing combustion gas from a blast burner to a smoke pipe section in a lithium bromide dilute solution reservoir to boil the lithium bromide solution to generate a concentrated solution and a refrigerant vapor. Since such a conventional device is horizontally long, the installation space is large,
In addition to occupying a large volume, it also has a large amount of solution and has a slow load response. Further, since it is a horizontally long type, it is necessary to use a blast burner having a long flame length, and such a burner has a high noise value, requires periodic inspections, and is a disadvantage of high cost. Further, since the furnace tube portion and the smoke tube portion, that is, the combustion chamber and the heat exchange portion are separately configured, it is difficult to improve the compactness of the conventional apparatus. While repeating trial and error, the inventors of the present invention have found that there is a difficulty in improving the conventional device, and arrived at the present invention by thinking from a completely different angle.

(Structure of the Invention) In FIGS. 2 and 3, reference numeral 1 is a tubular body constituted by a heated liquid wall 2, and the tubular body 1 has an exhaust port 3 at its upper end.
And a liquid pipe 4 communicating with the heated liquid wall 2 is disposed inside the liquid pipe 4 so as to intersect the slant in the longitudinal direction, and fins 5 are attached to the liquid pipe 4. The tubular body 1
A burner 6 is installed at the lower end. According to the second aspect, the liquid pipe 4 according to the first aspect is configured such that the liquid pipe 4 crosses obliquely at the upper position of the liquid pipe.

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

At this time, since the liquid pipe 4 is piped so as to cross the slant in the vertical direction, the heat exchange becomes orthogonal and the heating efficiency is remarkably improved. That is, as described above, since the liquid pipe 4 is arranged so as to intersect the slant in the vertical direction in the vertical direction, the heat transfer area is increased, and the rising combustion gas is turbulently formed by the liquid pipe to heat the combustion gas. Greatly improve efficiency. When such a liquid pipe is crossed obliquely at the upper position, the combustion gas is not rapidly cooled in the space at the lower position, and as a result, the heat exchange as described above can be performed in the complete combustion state. There are advantages. In addition, since the liquid pipe 4 is formed in a slanted shape, there is an advantage that the air inside the pipe can be easily removed from the inside of the pipe.

As described above, since the combustion chamber and the heat exchange section are integrated with each other and the heating efficiency is improved as described above, further compactness can be achieved. In fact, compared with the conventional device, the size of the installation area was 70 to 80%, and the occupied volume was 20 to 30%. Further, by making the apparatus itself vertical, it is possible to use a short-flame burner that is normally used, and it is possible to easily maintain and manage and to achieve extremely low noise. Further, the vertically long structure can reduce the installation area.

(Effects of the Invention) As described above, according to the present invention, by making the playback device have a unique configuration, it is possible to achieve compactness and at the same time,
In addition to providing a low-cost reproducing device with little noise and requiring almost no maintenance, it has a great advantage that the installation area can be reduced.
