Generally, a vacuum hot water boiler operated by keeping the inside of a vacuum is low in equipment cost, safe, high in operation efficiency, and advantageous in energy saving. It boasts low boiling point and less corrosion than existing boilers, and has a lifespan of more than three times. However, there is a disadvantage that a phenomenon of breakage of the vacuum is likely to occur during long-time heating.

First, a general configuration of a vacuum circulation boiler according to an embodiment of the present invention will be described with reference to FIG.

The vacuum circulation type boiler according to the present embodiment includes a main body 100 in which high temperature steam is generated by heating internal heating water by a burner 150 and a vacuum pump 120 connected to the main body 100 to absorb high- A heating device 200 in which heating is performed through heat exchange between the pump 240 and the high temperature steam supplied from the main body 100 and a condenser 300 for storing the condensed water generated in the course of passing through the heating device 200 ). &Lt; / RTI >

Particularly, in the present invention, a condensate water supply pipe 360 provided with a condensate water control valve 361 is connected to supply the condensate water stored in the condenser 300 to the main body 100 as needed, A vacuum control pipe 170 provided with an air control valve 171 is connected to control the degree of internal vacuum through control of inflow amount of outside air and a vacuum gauge 310 for checking the degree of vacuum is constructed in the condenser 300 .

The main body 100 includes a low level sensor 110 and a high level sensor 130 for detecting the internal level of the main body 100. Between the low level sensor 110 and the high level sensor 130, 120 are additionally provided.

The main body 100 is connected to a direct water supply pipe 180 capable of direct water supply control by the direct water control valve 181 when the internal water level drops due to insufficient heating water, 161 are connected to each other through a discharge pipe 160 so that they can be discharged to the outside.

The main body 100 is connected to a steam recovery pipe 270 through which the waste steam discharged to the outside through the condenser 300 and then discharged through the vacuum pump 240 is connected to the steam recovery pipe 270 Is provided with a regulating valve 271 for regulating the amount of recovered steam.

Reference numeral 140 denotes a temperature sensor for sensing the temperature inside the main body 100. Reference numeral 260 denotes a check valve for preventing backflow. Reference numeral 320 denotes a level sensor. Reference numeral 340 denotes a temperature sensor. Reference numeral 350 denotes a control valve 351, respectively.

It is preferable that the control valves 161, 171, 181, 271, 351, and 361 in this embodiment are solenoid valves that are automatically opened and closed by the control unit.

Hereinafter, the operation and effect of the vacuum boiler according to the present invention will be described.

The vacuum pump 240 is turned on to turn off the vacuum pump 240 when vacuum pressure of about 10 to 15 Torr is formed on the main body 100, the heater 200, and the condenser 300, When the temperature sensor 140 of the main body 100 senses 70 ° C by igniting the burner 150 of the boiler, the steam of the main body 100 is discharged to the radiator 200 as the vacuum pump 240 is turned on. Indoor heating is continued while passing.

When the temperature sensor 340 of the condenser 300 senses 60 ° C in this driving process, the burner 150 is turned off.

When the condensation water level in the condenser 300 gradually increases due to condensation of steam as time elapses in the steam circulation process and a sensing signal is generated in the water level sensor 320, the condensate water control valve 361 and the air conditioning The valve 351 is opened so that the condensed water in the condenser 300 can be supplied to the main body 100 through the condensed water supply pipe 360.

The condensed water vapor passed through the condenser 300 is discharged to the outside through the vacuum pump 240. Since the discharged waste steam has heat, some of the waste steam is discharged through the steam return pipe 270 to the main body 100). &Lt; / RTI >

That is, at this time, when the control valve 271 is opened, the waste steam discharged to the outside is recovered through the steam recovery pipe 270, so that the waste heat source can be utilized.

On the other hand, when steam is generated in the main body 100, the amount of heating water in the main body 100 is reduced, and when the water level falls below the low water level sensor 110, direct water is supplied from the outside by control of the controller.

That is, at this time, the direct water control valve 181 is opened, so that the replenishing water can be replenished to the main body 100 through the direct water supply pipe 180, Until the detection is made.

When the heating water level in the main body 100 rises and reaches the high-level sensor 130, the discharge control valve 161 is opened to discharge the heated water through the discharge pipe 160.

Meanwhile, the internal vacuum degree of the boiler can be checked through the vacuum gauge 310 formed in the condenser 300, and when the degree of vacuum is too high or low, the vacuum degree is controlled by the vacuum control pipe 170.

That is, when the air control valve 171 is opened, external air flows through the vacuum control pipe 170 to lower the degree of vacuum. When the degree of vacuum is low, the air control valve 171 is closed to increase the degree of vacuum .

Therefore, by controlling the air control valve 171, the optimum degree of vacuum suitable for the circulation of the steam can be uniformly maintained, and the circulation of the steam can be smoothly performed.
