1 is a block diagram showing the structure of a packaged heat collecting device of a solar boiler system to which the technology of the present invention is applied, and according to the present invention, the high temperature heat obtained from the heat collector 10 using solar heat is transferred to the boiler 20. In the solar boiler system is connected to the collector 10 using the solar heat is supplied after the high temperature heat via the heat collecting supply pipeline 30 and the boiler 20 to transfer the conductive liquid heated to a high temperature is returned The collected heat supply pipeline 30 is connected so that the water can be supplied directly

It is also connected to the water line (T) provided with a check valve (T-2) (T-3) for preventing backflow installed on both sides of the pressure reducing valve (T-1) and the seaside valve (T-1). Connect the air separator tank 40 is temporarily stored via the conductive fluid.

In this case, the air separator tank 40 may further use an air vent 41, a pressure gauge 42, and an expansion tank 43, and a heat collecting supply pipeline of a portion connected to the air separator tank 40 may be used. 30, it is preferable to provide a check valve (30-1) to prevent the back flow.

The low temperature drainage pipe line 50 is installed to transfer the low temperature conductive liquid stored in the air separator tank 40 to the collector 10, and the conductive liquid is a mixture of ordinary water and antifreeze.

The pump means 60 is installed on the low temperature drainage pipe line 50 connecting the air separator tank 40 and the collector 10, and the low temperature drainage pipe line 50 to maintain the concentration of the conductive liquid at a set concentration. The antifreeze auxiliary tank 70 for refilling antifreeze is installed.

On the other hand, the antifreeze auxiliary tank 70 is installed on the low temperature drainage pipeline 50 between the inlet side of the pump means 60 and the air separator tank 40 so that the conductive liquid supplemented with the existing conductive liquid is easily provided. It is preferred to allow mixing. This is because the supplemented antifreeze can be easily mixed with the existing conductive solution, thereby increasing the efficiency of the system.

A conductive liquid supply supply pipe line 70-1 connecting the heat collecting supply pipeline 30 connected to the air separator tank 40 and the antifreeze auxiliary tank 70 is installed in the air separator tank 40. It is connected to the drain pipe line (80A) is provided with a drain valve (80A-1) for discharging the conductive liquid to the outside.

Meanwhile, a conductive liquid discharge pipe line 80B having a manual valve 80B-1 installed therein is connected to the heat collecting supply pipe line 30 and the drain line 80A connected to the air separator tank 40, and the conductive line is installed. It is preferable to install a check valve 70-B in the liquid replenishment supply line 70-1.

In addition, the conductive liquid supply pipe line 80C constituting the heat collecting supply pipe line 30 and the antifreeze auxiliary tank 70 connected to the air separator tank 40 is installed, but in the conductive liquid supply pipe line 80C. When the pressure is generated higher than the set reference pressure is installed to operate the safety valve (80C-1) for converting the conductive liquid flowing through the heat collecting supply pipe line 30 to the antifreeze auxiliary tank 70.

The present invention having the structure as described above is installed in the housing 90 to protect the package-type heat collecting device by using a device made in advance during the installation of the boiler, the installation work is easy, simple and small, the boiler installation place is small It can be maintained to facilitate storage and transportation.

On the other hand, looking at the operation of the present invention having the structure as described above can be largely divided into the individual circulation operation showing the normal operating state of the package-type collector and the individual circulation operation showing the operation at the time of high pressure generated inside the package-type collector.

Referring to the normal operating state of the package-type collector first, as shown in the accompanying drawings, as shown in FIG. 2, solar heat is collected by the collector 10, and when the temperature of the conductive solution is heated to a high temperature, the high-temperature conductive solution is collected in a heat collecting supply pipeline 30. Heat exchange is performed inside the boiler via the pre-installed boiler 20 and the high-temperature conductive liquid becomes low temperature and is temporarily transferred to the air separator tank 40.

The pressure that can flow through the collector 10 or each pipeline is because the pump means 60 is operating, and after collecting the high temperature heat via the boiler 20, the heat collecting supply pipeline 30 is returned. The connection is transferred to the air separator tank 40 and the conductive liquid is stored.

In the air separator tank 40, the air contained in the conductive liquid is separated, so that the air, which is a gas at the upper part, and the conductive liquid in the liquid state at the lower part, separate the air contained in the conductive liquid using the air vent 41. Ejected to the outside, the pressure can be checked using a pressure gauge (42).

On the other hand, since the amount of the conductive liquid is reduced by evaporation, it is configured to receive water directly by using a direct water line (T).

Pressure control is made to maintain a constant pressure of the water supplied at a high pressure to be directly supplied with water by using the direct water line (T) by a pressure reducing valve (T-1) to supply water directly, and a check valve for preventing backflow (T-2). (T-3) prevents reverse flow of the conductive liquid.

Since the conductive liquid stored in the air separator tank 40 is in a low temperature state, it is transferred to the collector 10 through the low temperature drainage pipeline 50 by the pump means 60 and heated again to a high temperature.

When the high pressure is generated inside the packaged collector, the pressure is increased while the conductive liquid is heated by the collector 10 at the time of power failure or when the pump means 60 is broken, as shown in FIG. 3A. If only the temperature rise and the pressure rise according to the low temperature and pressure drop due to heat exchange does not occur, the pressure rises in each pipeline and air separator tank 40 to increase the risk of breakage, if the pressure is higher than the set reference pressure The safety valve 80C-1 installed in the conductive liquid supply pipe line 80C for converting the conductive liquid flowing through the heat collecting supply pipeline 30 to the antifreeze auxiliary tank 70 operates to conduct the flow flowing through the heat collecting supply pipeline 30. By switching the liquid to the antifreeze auxiliary tank 70, the pressure can be lowered to maintain and secure the stability.

When the pressure is lowered to a predetermined constant pressure, the operation of the safety valve (80C-1) is stopped to return to normal operation as shown in FIG. The safety valve (80C-1) operation is an example of the automatic operation, by manually operating the manual valve (80B-1) installed on the conductive liquid discharge pipe line (80B) as shown in Figure 3b attached to the heat collecting pipe The conductive liquid flowing through the line 30 may be discharged to induce a pressure drop.

On the other hand, by using the drain valve (80A-1) on the drain pipe line (80A) installed to the air separator tank 40, the conductive liquid filled in the air separator tank 40 may be discharged. The drain valve 80A-1 on the line 80A is used for internal cleaning.
