Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a gas-liquid separator for an absorption refrigeration system.

[0002]

2. Description of the Related Art In an absorption refrigerating apparatus using, for example, water as a refrigerant and lithium bromide as an absorbing liquid, a dilute solution after the completion of absorption is heated and boiled by a high-temperature regenerator and then cooled by a gas-liquid separator. It separates into a vapor and an intermediate concentrated solution (for example, see Japanese Patent Publication No. 6-21743).

As described above, in the case of an absorption refrigeration system using, for example, a water-lithium bromide-based working medium,
In general, the structure of the gas-liquid separator itself is relatively simple compared to the ammonia-water system that requires a rectifier,
This is also advantageous in terms of miniaturization and cost reduction of the refrigeration apparatus itself.

However, since the gas-liquid separation efficiency of the gas-liquid separator affects the absorption / refrigeration performance in the subsequent refrigeration cycle, the gas-liquid separation efficiency is reduced as much as possible while simplifying the structure and reducing the cost. Various improvements have been made to improve efficiency.

[0005] As one of the conventional examples of such a gas-liquid separator, there is one disclosed in, for example, JP-A-7-190554.

In the structure of the prior art, an intermediate concentrated solution partition having a predetermined height is provided inside a bottomed cylindrical outer body, and a lower portion having a lower height is provided inside the intermediate concentrated solution partition. Each of the refrigerant partitioning tubes is provided, and a liquid supply pipe for supplying a dilute solution from the high-temperature regenerator is introduced to a predetermined height position of the refrigerant partitioning tube, and a predetermined distance is provided above the liquid collecting tube at a predetermined interval. An impact plate having a width is provided in an umbrella shape. Then, a high-temperature dilute solution (boiling gas-liquid) in a gas-liquid two-phase state from a high-temperature regenerator discharged from the pumping pipe at a predetermined supply pressure is caused to collide with the collision plate to separate the refrigerant vapor and the intermediate concentrated solution. It has become.

[0007]

However, the above configuration has the following problems.

(1) The intermediate concentrated solution component after colliding with the collision plate is easily scattered, and the gas-liquid separation efficiency is poor.

(2) As a result, the intermediate concentrated solution is apt to be mixed into the refrigerant vapor side. When the intermediate concentrated solution is mixed with the refrigerant vapor, the condensation ability of the condenser and the evaporation ability of the evaporator are reduced, and the apparatus and the system are corroded.

(3) If an attempt is made to improve the gas-liquid separation efficiency, the size of the main body of the gas-liquid separator becomes large, and there is a limit to downsizing.

(4) Since the collision plate and the partition tube are separate bodies, the number of parts is large, and working and assembling also require many man-hours.

The present invention has been made to solve such a problem. In the gas-liquid separator main body, a partition wall for separating and preserving a refrigerant vapor and an intermediate concentrated solution and an impingement plate are integrated. An object of the present invention is to provide a gas-liquid separator for an absorption refrigeration system which has a high gas-liquid separation efficiency, has a simple structure and is inexpensive, by being combined.

[0013]

In order to achieve the object, the present invention is provided with the following means for solving the problems.

That is, the gas-liquid separator for an absorption refrigerating apparatus of the present invention is a gas-liquid separator for an absorption refrigerating apparatus for separating a dilute solution heated by a high-temperature regenerator into a refrigerant vapor and an intermediate concentrated solution. A cylindrical separator body; a partition plate for partitioning at least a predetermined depth portion in the separator body into two horizontal chambers of a collision separation chamber and a gas-liquid storage chamber; and a predetermined height position of the partition plate. And a collision plate of an integral structure which extends a predetermined width in the direction of the collision separation chamber.

More specifically, the partition plate is provided with an intermediate concentrated solution outlet for regulating the liquid level of the intermediate concentrated solution at a position lower than the collision plate.

That is, in this configuration, first, a boil-off gas from the high-temperature regenerator is introduced and collided to separate the refrigerant vapor and the intermediate concentrated solution into a collision plate, and the refrigerant vapor and the intermediate concentrated solution after the collision separation are stored. The partition plate forming the chamber is integrated and shared.

Accordingly, the number of parts is reduced, the structure and assembly are simplified, the cost is reduced, and the collision separation chamber for performing collision separation and the refrigerant vapor and intermediate concentrated solution storage chamber are integrated with a partition plate. It is surely divided by the impact plate,
As in the related art, it is possible to minimize the mixing of the intermediate concentrated solution into the refrigerant vapor.

The partition plate thus configured is provided with an intermediate concentrated solution discharge port located below the collision plate so that the level of the separated intermediate concentrated solution in the storage state can be reduced. It is regulated to a desired level.

Therefore, the liquid level can be prevented from fluctuating, and the liquid level (head) can be easily controlled.

[0020]

As described above, according to the gas-liquid separator for an absorption refrigeration system of the present invention, the following advantageous effects can be obtained.

(1) The gas-liquid separation efficiency between the refrigerant vapor and the intermediate concentrated solution is improved, and the absorption performance is improved.

(2) Since the mixing of the intermediate concentrated solution into the refrigerant vapor is reduced, the condensation in the condenser and the decrease in the evaporation ability in the evaporator are prevented, and the corrosion of the device and each part of the system is prevented. Is prevented.

(3) Since the collision plate and the partition plate are configured as a single component, the number of components is reduced, the configuration and assembly are simplified, and the cost is reduced.

It is formed in a semi-elliptical shape with external dimensions that can be kept.

At the lower position of the partition plate 3, an intermediate concentrated solution discharge port 9 having a liquid level control function having a predetermined vertical width which is long in the front-rear direction is provided as shown in the figure. Therefore, the boiling gas-liquid from the high-temperature regenerator discharged from the tip of the pumping tube 6 at a predetermined discharge pressure collides with the back surface of the collision plate 8 and does not scatter to the second space 4b side. Gas liquid 2
The refrigerant vapor is separated into phases, and the refrigerant vapor rises from the gap around the outer periphery of the collision plate 8 toward the refrigerant vapor storage space 11 above the second space 4b, while the intermediate concentrated solution falls downward and stays there. When the liquid level L becomes higher than the concentrated solution discharge port 9, the liquid is supplied from the bottom of the second space 4 b below the refrigerant vapor storage space 11 to the low temperature regenerator via the intermediate concentrated solution supply pipe 7.

Further, in the refrigerant vapor storage space 11 above the collision plate 8 in the separator body 2 communicating with the second space 4b, a refrigerant vapor supply pipe 12 to the low temperature regenerator side is provided.
Are open through the ceiling 19 of the separator body 2. Then, the refrigerant vapor in the refrigerant vapor storage space 11 is supplied to the low-temperature regenerator through the refrigerant vapor supply pipe 12.

As described above, the gas-liquid separator for the absorption type refrigeration system according to Embodiment 1 of the present invention uses the high temperature gas-liquid two-phase dilute solution heated by the high temperature regenerator in the middle of the refrigerant vapor and the intermediate solution. Upon separation into a concentrated solution, a cylindrical separator body 2 with a bottom serving as a main casing of the gas-liquid separator 1 and at least a predetermined depth of the separator body 2 are introduced with a boiling dilute solution from a high-temperature regenerator.

In addition, it is possible to minimize the mixing of the intermediate concentrated solution into the refrigerant vapor.

The partition plate 3 thus constructed

For example, in the case of an air-cooled absorption refrigeration system in which the heat absorbed in an absorber is cooled by an air-cooling system, an absorption / evaporator for cooling is generally used in combination with a cooling / heating device for taking out heat even during a heating operation in winter. However, since heat loss will increase if it is used, a dedicated heater is usually provided separately. Further, the diluted solution supplied to the high-temperature regenerator 1 after the completion of the absorption action is transported by a solution pump. However, in order to prevent empty cooking and control the liquid level in the high-temperature regenerator. A dilute solution receiver is provided in the high-temperature regenerator, and liquid level control means such as a float valve is provided therein.

However, in the case of a configuration in which a heater is provided separately from the gas-liquid separator, the heat loss of the high-temperature refrigerant and the absorption liquid is large, and a configuration in which a dilute solution receiver and liquid level control means are separately provided on the high-temperature regenerator side. In this case, there is a problem that the structure of the high-temperature regenerator is complicated.

Therefore, in the present embodiment, in order to solve the problem, by integrating the heater and the dilute solution receiver with the gas-liquid separator, the switching of the cooling / heating operation is performed by the refrigerant vapor and the intermediate concentration.

The collision plate 8 has a size sufficient to cover the opening at the tip of the liquid pumping tube 6 as in the first embodiment, for example.
It is formed in an elliptical shape having a dimension to keep a predetermined interval between the inner peripheral surface of the side wall portion.

The storage solution level of the separated intermediate concentrated solution is regulated to an appropriate level. In this case, particularly in the case of the present embodiment, a large number of Punching holes 15, 15, ...
Since the first and second baffle plates 13 and 14 provided with are provided, and the refrigerant vapor is extracted to the low-temperature regenerator through the first and second baffle plates, the intermediate concentrated solution is mixed into the refrigerant vapor. Can be difficult.

On the other hand, the dilute solution receiver 16 is formed by a bottomed cylindrical receiver body 17 having an inner diameter sufficient to incorporate the gas-liquid separator 1 having the above-described structure.
The surface is continuously integrated with the bottom portions 5a and 5b surfaces of the gas-liquid separator 1, while the refrigerant vapor supply pipe 12 to the low-temperature regenerator passes through the closed ceiling 19 as described above. Dilute solution supply pipes 21 from the high-temperature solution heat exchanger penetrate through the side wall portion 20 and are respectively opened.

In addition, easy liquid amount control can be realized.
