Description

[Detailed description of the invention] The present invention relates to heat recovery and absorption heat pumps.

Conventionally, absorption type heat pumps have been used to recover waste heat, and this system is shown in Figure 1. That is, the heat removal fluid (a) is passed through the inner metal of the evaporator (1), where heat is removed by evaporation of the refrigerant, and the fluid is vaporized. ! The 6 medium moves to the absorber (2) and heats the fluid to be heated (eg boiler feed water) (b) passing through the absorber (2). Further, a part of the exothermic fluid (a) is guided to the regenerator (3) without passing through the evaporator (1), and is sent from the absorber (2) via the pump (4). The refrigerant in the collected liquid (Cl) is heated to evaporate the refrigerant in the collected liquid.Then, this vaporized refrigerant is further transferred to the condenser (5).
cooling fluid (e.g. cooling water) (d) and is condensed by the pump (6), (7) fc to the evaporator (1).
) will be sent to. Note that the concentrated absorption liquid (e) regenerated in the regenerator (3) is sent to the absorber (2) by the pump (8), but on the way, it is transferred to the concentrated absorption liquid (e) via the heat exchanger (9). c.
), conventionally, according to such devices, only a heated tube for one type of heated fluid is arranged in the absorber (2), and for example, a heated tube for a different type of heated fluid is disposed in the absorber (2). When it is necessary to heat fluids at the same time, an absorption heat pump must be installed for each fluid to be heated, which is uneconomical.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a heat recovery and absorption heat pump that can eliminate the above-mentioned drawbacks.

That is, the present invention provides an absorption heat pump having an evaporator, an absorber, a regenerator, and a condenser, in which the interior of the absorber is divided into a plurality of chambers, and a separate tube to be heated is provided in each of these chambers. This is what was placed.

According to this configuration, it is possible to simultaneously heat many kinds of fluids to be heated using the -based absorption heat pump, which is very economical.

An embodiment of the present invention will be described below with reference to FIGS. 2 and 3. (B) is an evaporator that evaporates the refrigerant, an absorber that absorbs all of the refrigerant vaporized by the evaporator (B), and an absorber @ that heats the liquid that has absorbed the refrigerant to release the refrigerant. 0 is a regenerator that evaporates and obtains a concentrated absorption liquid, 0 is a condenser that condenses the refrigerant vaporized in the regenerator, 4 is a pump that sends the collected liquid (D) to the regenerator (2), and qQ is a concentrated absorption A pump that sends the liquid (D) to the absorber, a heat exchanger that transfers the heat of the collected liquid (D) between the concentrated absorbing liquid and recovers it, and a refrigerant IF)
This is a pump that sends the water into the evaporator Oυ. By the way, as shown in FIG. 3, the evaporator (b) and the absorber side are provided with - cylinders @17]K and D valves of the main partition plate in the vertical direction and are disposed adjacent to each other. Also, inside the absorber, a plurality of (two in the non-example) space chambers (23
A) (23B), and further these space chambers (23A
) (23B) and the inside of the evaporator I are each separately,
They are communicated via a current plate (c) and an eliminator (4). In each of the space chambers (23AX23B), separate energized tubes (heat exchanger tube group) (26A) (26
B) is placed. In addition, (branch) is a heating tube (heat exchanger tube group) arranged in the evaporator I. Further, although not shown in detail, the regenerator @ and the condenser q4 are provided adjacent to each other in one cylinder with a partition plate interposed therebetween.

Next, we will explain the heat recovery effect. A part of the waste fluid particles passes through the heating tube in the evaporator (b), where heat is taken away by the evaporation of the refrigerant, and this vaporized refrigerant (F ) of the heated fluid that passes through the eliminator 4 and the rectifying plate (to), moves into each space chamber (23AX23B) of the absorber 0, and flows in each heated tube (26A) (26B). (Heating 0. - 10,000, the remaining exothermic fluid is passed through the heating tube in the regenerator side, where the refrigerant in the liquid collected ①) is evaporated. The vaporized refrigerant moves into the condenser CI4 and is condensed by the cooling fluid (G) flowing through the cooling pipe.

As described above, according to the above-mentioned embodiments, it is possible to simultaneously heat many types of fluids to be heated using the -based absorption heat pump, which is very economical.

Incidentally, in the above embodiment, the R thermal fluid (A) passing through the evaporator and regenerator side was explained as one type, but for example, the inside of these evaporator (6) and regenerator (13) is ), it is divided into a plurality of chambers, and each chamber is provided on the heating pipe through which the waste heat fluid passes. Heat recovery can be performed.
