The present invention relates to a non-condensable gas removal device that immediately removes non-condensable gas that tends to stay near the area.

Conventionally, in a boiler/condensing turbine plant in which a boiler, turbine, condenser, and condensing pump are connected by piping, the evaporation section (heat receiving section) of a heat pipe type heat exchanger is used to collect exhaust gas (i.e., heated fluid) from the boiler. The condensing part (heat radiation part) of the heat pipe heat exchanger is placed in the line for fuel or combustion air (i.e. heated fluid) to the boiler, and the exhaust heat held by the exhaust gas is transferred to the boiler. Devices for feeding and recovering fuel or combustion air are known.

と凝縮部との間を作動流体が相変態しながら循環
するようになつている。 In this exhaust heat recovery device, when the evaporation section and the condensation section are separated from each other by a considerable distance, a separate heat pipe heat exchanger is used.
Its operating principle is that the evaporation section and condensation section of a separate heat pipe heat exchanger are connected by two mutually insulated pipes, and the vapor of the working fluid (usually pure water) is transferred to the evaporation section. The condensate flows from the condensate through one pipe to the condensing part, and the condensate flows from the condensing part to the evaporating part through the other pipe, thereby causing a phase transformation of the working fluid between the evaporating part and the condensing part. It is becoming more and more cyclical.

て、熱交換の効率を低下させる。 In an exhaust heat recovery device using such a separate heat pipe heat exchanger, non-condensable gas (mainly air and dissolved oxygen) may be generated in the working fluid system of the separate heat pipe heat exchanger. The generated non-condensable gas obstructs the movement of the working fluid or occupies the condensing section, reducing the efficiency of heat exchange.

を正圧にして放散している。 The conventional method for eliminating such non-condensable gas is that when the pressure in the system of a separate heat pipe heat exchanger is positive, it can be dissipated by simply opening it, but when the pressure is negative, For example, JP-A-57-199777, JP-A-58-123088, JP-A-58-
As disclosed in Japanese Utility Model Application No. 106743 and Japanese Utility Model Application Publication No. 106743 and Japanese Utility Model Application Publication Nos. 106743 and 107469, an evacuation device using a pressure difference using a pump is used. In addition, when a pump is not installed, the load on the heat equipment of the heat source is increased, and the inside of the system of the separate heat pipe heat exchanger is made positive pressure and dissipated.

However, in the case of a non-condensable gas removal device in such a conventional separate heat pipe heat exchanger, it is necessary to operate a dedicated pump, increase the load on the heating equipment of the heating source, and reduce the pressure in the system. There was a problem in that special work time was required to eliminate the non-condensable gas, such as by applying positive pressure and dissipating the non-condensable gas.

することを目的とするものである。 This invention was made by focusing on these conventional problems, and it is necessary to operate a dedicated pump and heat in an exhaust heat recovery device using a separate heat pipe heat exchanger in a boiler/condensing turbine plant. This eliminates the need for special work to eliminate non-condensable gas, such as increasing the load on heat equipment at the source, and immediately eliminates non-condensable gas generated in the system of the separate heat pipe heat exchanger, thereby improving heat exchange. The purpose is to prevent a decrease in efficiency.

Therefore, a non-condensable gas removal device in an exhaust heat recovery device for a boiler/condensing turbine plant according to the present invention connects a boiler, a turbine, a condenser, and a condensing pump through piping to form a boiler/condensing turbine plant. In an exhaust heat recovery device that uses a separate heat pipe heat exchanger to recover exhaust heat held by exhaust gas from the boiler of the plant, a non-condensable gas retention section near the condensation section of the separate heat pipe heat exchanger is provided. and the condenser are connected by piping, and the condensate pump outlet and the working fluid supply section of the separate heat pipe heat exchanger are connected by piping.

The action of the non-condensable gas removal device in the exhaust heat recovery device of the boiler/condensing turbine plant to which this invention relates is that the working fluid ( A portion of the purified water is constantly passed through the condenser,
The resulting shortage of working fluid is replenished by supplying the working fluid (pure water) of the boiler/condensing turbine plant from the condensate pump output side to the working fluid supply section of the separate heat pipe heat exchanger. Ru.

Therefore, the non-condensable gas is immediately removed without remaining in the system of the separate heat pipe heat exchanger, and the heat exchange is performed without blocking the movement of the working fluid or occupying the condensing section. This prevents deterioration of efficiency and does not require special work to eliminate non-condensable gases.

As a result, it becomes high-temperature, high-pressure steam. This steam rotates the turbine 2, which drives, for example, a generator (not shown) to generate electricity. turbine 2
The low-temperature, low-pressure steam that exits is condensed in a condenser 3 to become pure water, pumped by a condensate pump 4, degassed in a deaerator 5, and supplied to the boiler 1.
Repeat this cycle.

圧送され、このサイクルを繰り返す。 In the exhaust heat recovery device, the pure water that has circulated through the pipe 13 to the evaporator 9 is heated by the exhaust gas (heated fluid) in the exhaust gas line 8 in the evaporator 9 and becomes steam, and this steam is converted into steam in the condenser 10. The blast furnace gas (fluid to be heated) in the supply line 7 is heated, and thus the heat held in the exhaust gas is recovered. The steam itself that heats the blast furnace gas in the condensing section 10 is condensed into pure water, which is temporarily stored in a condensed water tank 11 and fed under pressure to the evaporation section 9 by a circulation pump 12, and this cycle is repeated.

自動的に行われる。 In the non-condensable gas removal device, the condenser 3 is operated at negative pressure (usually about -0.05Kg/cm 2 abs or 0.95Kg/cm 2 G), so the separate heat pipe heat exchanger A small portion of the working fluid (that is, pure water) always flows into the condenser 3 via the piping 14 from a portion downstream of the condensing section 10 where non-condensable gas tends to accumulate. At this time, the amount of pure water flowing through the pipe 14 is adjusted by the valve 16. Furthermore, when the liquid level of the condensed water tank 11 decreases, the liquid level control valve 18 opens, and pure water is supplied from the condensate pump 4 to the condensed water tank 11 via the piping 17, and the separate type heat pipe heat exchanger The shortage of pure water in the system is replenished, and the amount of pure water in the system is controlled to be always constant. This liquid level control is performed automatically.
