Description

Technical Field

[0001] The present application relates to the technical field of deaerators, and in particular to a partition-type thermal deaerator used in a nuclear heating reactor. Background Art

[0002] Thermal deaerator (rotating film deaerator) is a new type of deaerator, which can remove dissolved oxygen and other gases in the feed water of the thermal system, prevent the corrosion of thermal equipment, and is an important equipment to ensure the safe operation of power plants and industrial boilers. The main method of thermal deaerator is to use steam to heat the feed water, increase the water temperature, so that the partial pressure of steam on the water surface gradually increases, while the partial pressure of dissolved gas gradually decreases, and the gas dissolved in the water continuously escapes. When the water is heated to the boiling temperature under the corresponding pressure, the water surface is full of water vapor, the partial pressure of dissolved gas is zero, and the water no longer has the ability to dissolve gas, that is, the gas dissolved in the water, including oxygen, can be removed.

[0003] Since most traditional thermal deaerators heat water directly with a heat source, during this process, the heat source comes into direct contact with water, which can easily cause water pollution; especially in nuclear power projects, since the heat source of nuclear power projects may contain radioactive substances, it is more likely to cause water pollution if it comes into direct contact with water. Summary of the invention

[0004] In order to reduce water pollution, the present application provides a partition-type thermal deaerator applied to a nuclear heating reactor, which adopts the following technical solution: A partition-type thermal deaerator applied to a nuclear heating reactor, comprising: Deaerator body; The heat exchanger is inserted into the deaerator body and arranged near the bottom water outlet of the deaerator body.

[0005] By adopting the above technical solution, the heat source liquid generated by the nuclear power project enters the heat exchanger, the heat exchanger heats the water in the deaerator body, and the heat source liquid after heat exchange is circulated and discharged through the heat exchanger outlet. Since the water in the deaerator body is heated indirectly through the heat exchanger, the heat source does not come into direct contact with the water, thereby reducing water pollution.

[0006] Optionally, the partition-type thermal deaerator further comprises: A temperature control component, used to adjust the temperature of the heat source liquid entering the heat exchanger; The temperature control component comprises: A regulating shell, one end of which is provided with a heat source inlet, a steam inlet and a coolant inlet, and the other end of which is provided with a heat source outlet and a discharge port; the steam inlet can be communicated with the steam discharge port on the deaerator body, and the heat source outlet is communicated with the inlet on the heat exchanger; the discharge port is communicated with a first solenoid valve; the steam inlet and the coolant inlet are both communicated with a second solenoid valve; A regulating coil is installed in the regulating shell, and multiple groups are arranged along the axial direction of the regulating shell; the head end of the first group of regulating coils is connected to the heat source inlet, and the tail end of the last group of regulating coils is connected to the heat source outlet; The heat source discharge branch pipe is connected to the adjacent control coil connection point and is connected to the connection point of the last group of control coils and the heat source outlet; the water outlet of the heat source discharge branch pipe is connected to the heat source outlet; The opening and closing assembly is arranged between adjacent regulating coils and between the last group of regulating coils and the heat source outlet, and is used to control the connection between adjacent regulating coils, the connection between the regulating coils and the heat source discharge branch pipe, and the connection between the regulating coils and the heat source outlet.

[0007] By adopting the above technical solution, since the best deoxygenation effect is usually to heat water to near the boiling point, when the heat source temperature is too high, it will easily cause the water to overboil. When the water overboils, it will affect the deoxygenation effect. Therefore, when the heat source temperature is relatively high, the heat source liquid enters the regulating coil through the heat source inlet and exchanges heat with the coolant in the regulating coil, thereby reducing the temperature of the heat source liquid. The heat source liquid with reduced temperature enters the heat exchanger through the heat source outlet.

[0008] Optionally, the opening and closing component includes: The connecting pipe is arranged between adjacent regulating coils and is connected to the adjacent regulating coils; the connecting pipe arranged at the last group of regulating coils is connected to the regulating coils and the heat source outlet; the heat source discharge branch pipe is connected to the connecting pipe near the previous regulating coil; A third solenoid valve is installed at the connecting pipe near the latter regulating coil and at the connecting pipe near the heat source outlet; The fourth solenoid valve is installed on the heat source discharge branch pipe near the connecting pipe.

[0009] By adopting the above technical solution, for example, two regulating coils are provided. During heat exchange, if the temperature of the first regulating coil is still relatively high after heat exchange, the third solenoid valve in the first opening and closing component can be controlled to open, so that the heat source liquid continues to flow to the second regulating coil for heat exchange again; then the fourth solenoid valve in the second opening and closing component is opened, so that the heat source liquid that has completed the heat exchange enters the heat exchanger through the second heat source discharge branch pipe; if the temperature of the first regulating coil meets the requirements after heat exchange, the fourth solenoid valve in the first opening and closing component can be controlled to open, so that the heat source liquid enters the heat exchanger through the first heat source discharge branch pipe; it can be adapted to different heat exchange requirements, thereby improving applicability.

[0012] By adopting the above technical solution, when the current regulating coil is performing heat exchange, the coolant can be blocked from flowing to the rear area, so that the coolant can fully exchange heat with the heat source liquid.

[0014] By adopting the above technical solution, the rotation of the middle rotary joint can be driven by the rotating component, thereby realizing the rotation of the regulated coil to stir the coolant, thereby improving the heat exchange efficiency.

[0015] Optionally, the rotating component includes: A rotating motor is installed on the connecting pipe; A rotating main gear is coaxially fixedly connected to the output shaft of the rotating motor; The rotating slave gear is coaxially fixedly connected to the rotating end of the middle rotating joint and meshes with the rotating master gear.

[0016] By adopting the above technical solution, after the rotating motor is started, the rotating main gear drives the rotating slave gear to rotate, so that the rotating end drives the rotation of the regulating coil.

[0017] Optionally, the temperature control component further includes: The liquid collecting box is provided with a first connecting port, a second connecting port and a connecting outlet, and the connecting outlet is connected to the inlet of the heat exchanger; the heat source outlet includes a first heat source outlet and a second heat source outlet, the first heat source outlet is connected to the first connecting port, and the first heat source outlet is connected to the heat source discharge branch pipe, the second heat source outlet is connected to the second connecting port, and the second heat source outlet is connected to the last connecting pipe.

[0018] By adopting the above technical solution, when there is no need to exchange heat for the heat source liquid, the heat source liquid can directly pass through the regulating coil, enter the liquid collecting box from the second heat source outlet, and then enter the heat exchanger through the connecting outlet; when the heat source liquid needs to exchange heat, the heat source liquid after heat exchange can enter the liquid collecting box through the first heat source outlet, and enter the heat exchanger through the connecting outlet.

[0019] Optionally, the temperature control component further includes: A reflux housing is installed on the regulating housing; the bottom of the reflux housing is tilted and tilted toward the liquid collecting box; A liquid return plate is installed in the reflux shell and is inclined toward the heat source inlet; the heat source discharge branch pipe is connected to the discharge space formed by the liquid return plate and the bottom of the reflux shell; the first heat source outlet is connected to the discharge space; A liquid discharge pipe, one end of which is in communication with the regulating housing, and the other end of which is in communication with the liquid return plate and the liquid collecting space formed at the top of the reflux housing, and a liquid discharge solenoid valve is installed on the liquid discharge pipe; The liquid return component is used to recover the cooling liquid in the liquid collecting space into the regulating shell.

[0020] By adopting the above technical solution, when the temperature of the coolant at the end of the regulating shell is relatively low, the drain solenoid valve can be opened as needed to allow the coolant at the end of the regulating shell to enter the liquid collecting space, and then enter the head end of the regulating shell through the liquid return component, so that this part of the coolant continues to exchange heat with the heat source liquid to save energy.

[0021] Optionally, the liquid return component includes: Two rotating plates are provided, which are coaxially rotatably connected to the regulating housing, and the two rotating plates are spaced apart; A liquid return hopper is installed between the two rotating plates, and a plurality of liquid return hoppers are arranged along the circumference of the rotating plates, and the liquid return hoppers move synchronously with the rotating plates; a liquid inlet is provided on the regulating shell, and the liquid inlet is located between the two rotating plates; A cover body is installed on the liquid return housing and covers the liquid return hopper; A rotating gear ring is coaxially sleeved on the regulating housing and fixedly connected to one of the rotating plates; A rotating gear meshed with the rotating gear ring and rotatably connected to the cover body; The rotating motor is mounted on the cover body, and the output shaft is coaxially fixedly connected with the rotating gear.

[0023] In summary, the present application has at least the following beneficial effects: 1. The purpose of setting the heat exchanger inside the deaerator is that the heat source liquid generated by the nuclear power project enters the heat exchanger, and the heat exchanger heats the water in the deaerator to generate steam. The heat source liquid after heat exchange is circulated and discharged. Since the water is heated by the heat exchanger, the heat source does not come into direct contact with the water, thus reducing the pollution to the water.

[0024] 2. The purpose of setting up the temperature control component is that the best deoxygenation effect is usually to heat the water to near the boiling point.

Therefore, when the heat source temperature is relatively high, the heat source liquid enters the control coil through the heat source inlet and exchanges heat with the coolant in the control coil, thereby reducing the temperature of the heat source liquid. The heat source liquid with reduced temperature enters the heat exchanger through the heat source outlet. BRIEF DESCRIPTION OF THE DRAWINGS
