Abstract
The utility model provides a superior drainage inlet device for a large nuclear power inversion type high-pressure feed water heater. The high-pressure heater is one of the key equipments of a heat regenerative system in a nuclear power unit. The high-pressure heater uses the wet vapor pumped out by a moisture separator reheater to heat main water supply to lead the water supply to achieve the required temperature, thus ensuring the output force of the power plant unit and improving the circulated heat efficiency. The superior drainage inlet device for the large nuclear power inversion type high-pressure feed water heater comprises a cylinder body (1), wherein one end of the cylinder body is connected with a small sealing head (2); the other end of the cylinder body is connected with an arc-shaped plate (3); the arc-shaped plate is connected with a supporting plate (4) and a drainage pipe (5); the cylinder body is internally connected with a stainless steel lining ring (6); the small sealing head is provided with a water spraying pipe (8) with a waist-shaped hole (7); and a plugging plate (9) is arranged at one end of the water spraying pipe (8). The superior drainage inlet device is used for the large nuclear power inversion type high-pressure feed water heater.
Description
Technical field
The utility model relates to a kind of higher level's inlet device of large nuclear-power inversion type high-pressure feed-water heater; Be specifically related to the hydrophobic inlet device of a kind of large nuclear-power inversion type high-pressure feed-water heater higher level
Background technology
Large-scale 1,000,000 grades Vertical Channel Down High Pressure Heater designs invention in Jiangsu Tian Wan nuclear power station project.High-pressure heater is one of key equipment of heat regenerative system in the nuclear power generating sets, it is the moist steam that is used to from the separator extraction, heat main feedwater, making feedwater meet the requirements of temperature, thereby guaranteed exerting oneself and improving thermal efficiency of cycle of Power Plant.If high-pressure heater is stopped transport, Power Plant exert oneself and the thermal efficiency will reduce greatly, net heat consumption will be increased, and will force steam generator under undesired operating mode, to move, equipment failure rate is risen; Will make the suffered stress of parts such as partition board of steam turbine, blade surpass the design permissible value, influence unit output; Also usually threaten the safe operation of other equipment, even cause serious device damage accident
Summary of the invention
The purpose of this utility model provides a kind of structure with big hydrophobic chamber, causes the hydrophobic further energy dissipating of higher level, avoids the hydrophobic inlet device of large nuclear-power inversion type high-pressure feed-water heater higher level of the next hydrophobic impingement heat transfer pipe of high speed of higher level.
Above-mentioned purpose realizes by following technical scheme:
The hydrophobic inlet device of a kind of large nuclear-power inversion type high-pressure feed-water heater higher level, its composition comprises: cylindrical shell, described cylindrical shell one end connects little end socket, the described cylindrical shell other end connects the arc plate, described arc plate connects gripper shoe and drainage tube, connect the stainless steel grommet in the described cylindrical shell, described little end socket is equipped with the spray pipe that has mounting hole, and described spray pipe one end is equipped with closure plate.
The hydrophobic inlet device of described large nuclear-power inversion type high-pressure feed-water heater higher level, described spray pipe along the circumferential direction is distributed with one group of mounting hole.
The hydrophobic inlet device of described large nuclear-power inversion type high-pressure feed-water heater higher level, described arc plate and described gripper shoe are formed casing, and described drainage tube one end embeds in the casing.
Beneficial effect:
1. the hydrophobic inlet fairing of the utility model higher level inserts below the normal level of liquid, makes to be full of water in the rectifying tube, avoids the hydrophobic impact to water level of higher level, avoids water-level fluctuation.
Little end socket of the present utility model welds mutually with spray pipe, cylindrical shell respectively, and at inner barrel soldering stainless steel grommet, anti-sealing is to cylindrical shell corrosion impact.
Spray pipe of the present utility model is through calculating the most reasonable perforated area of choosing, and with the stainless steel pipe one group of mounting hole that along the circumferential direction evenly distributes, spray pipe welds mutually with closure plate, make the higher level hydrophobic from the ejection of spray pipe mounting hole fully by vapour, liquid separation.
The hydrophobic inlet device of the utility model higher level adopts big hydrophobic pocket cell structure and open 48 mounting holes on spray pipe by calculating, can make higher level's dewatering capacity-enlarging after, vapour, liquid can be separated fully, the effect of step-down energy dissipating.
The utility model has been taked the structure of big hydrophobic chamber at the spray pipe next stage, is convenient to the hydrophobic further dilatation through separating, and causes the hydrophobic further energy dissipating of higher level, avoids higher level's the hydrophobic impingement heat transfer pipe of high speed.
The utility model is provided with the arc plate and welds mutually with gripper shoe and constituted a casing below cylindrical shell; one end of drainage tube is inlayed in the casing; one end inserts below the ordinary water level liquid level; hydrophobic direct impact arc plate is flowed down along drainage tube; prevent hydrophobic direct impingement heat transfer pipe and liquid level; cause reduce the service life of heat exchanger tube, cause the inaccurate phenomenon of liquid level, effectively protect heat exchanger tube and prevent water-level fluctuation.
