Abstract
The utility model discloses a horizontal adverse current syllogic U -shaped pipe high pressure feed water heater, it includes that it includes casing, tube sheet, hydroecium, superheated steam cooling zone, saturated steam condensation segment, hydrophobic cooling zone, built -in exhaust apparatus, U -shaped pipe, and the hydroecium passes through the tube sheet and the casing links to each other, and the casing below is equipped with sliding support and fixing support. After adopting the horizontal type structure, the increase of water level control volume, the high control that adds the water level of being convenient for, the prevention water level is too high to be poured steam turbine or water level into and crosses low damage low reaches water -feeding pump, and furthest utilizes the steam superheating degree, adopts built -in exhaust apparatus, in time discharges and condenses in the incondensable gas of equipment, avoids corroding, and built -in exhaust apparatus condenses in the incondensable gas of equipment except that timely discharge, can also guide steam to press certain orientation and flow, and the cooperation guide plate uses, optimizes the heat transfer effect.
Description
Technical field
This utility model belongs to high-pressure heater, is specifically related to a kind of horizontal reversed flow syllogic U-tube high-pressure heater。
Background technology
High-pressure heater is a kind of to utilize the extracted steam from turbine heating feedwater heat transmission equipment to improve the thermal efficiency。It is generally adopted shell-and-tube heat exchanger。It is relatively big to there is installing space in Conventional upright high-pressure heater, the shortcomings such as water lev el control volume is little, and conventional high-pressure heater mostly is and only arranges a heat exchange section, for reaching heat transfer effect, it is necessary to arrange externally arranged steam cooler, its consumptive material is many, system complex, maintenance workload is big, now seldom adopts。
Summary of the invention
For the drawbacks described above overcoming prior art to exist, the purpose of this utility model is in that, it is provided that a kind of horizontal reversed flow syllogic U-tube high-pressure heater, it is simple and reasonable, stable, long service life。
The horizontal reversed flow syllogic U-tube high-pressure heater that this utility model provides, it includes it and includes housing, tube sheet, hydroecium, superheated steam cooling section, saturated vapor condensation segment, hydrophobic cooling section, built-in exhausting equipment, U-tube, hydroecium is connected with housing by tube sheet, housing is connected with sliding support and hold-down support, hydroecium is hemispherical, hydroecium both sides are provided with feed-water inlet pipe and feedwater outlet pipe, and feed-water inlet pipe is positioned at the lower section of hydroecium, and feedwater outlet pipe is positioned at the top of hydroecium；Superheated steam cooling section and hydrophobic cooling section are located on tube sheet side by side, and superheated steam cooling section is positioned at above hydrophobic cooling section, and saturated vapor condensation segment is positioned at superheated steam cooling section and hydrophobic cooling section rear；U-tube is located on tube sheet, lower end traverse superheated steam cooling section, saturated vapor condensation segment and hydrophobic cooling section；Steam inlet pipe is provided close on the upside of the housing of tube sheet, is connected with the superheated steam cooling section in housing, is provided with hydrophobic import and hydrophobic outlet on the downside of the housing relative with steam inlet pipe, is connected with the hydrophobic cooling section in housing；Built-in exhausting equipment is located on tube sheet。
The horizontal reversed flow syllogic U-tube high-pressure heater that this utility model provides, it has the beneficial effects that, after adopting horizontal type structure, water lev el control volume increases, it is easy to height and adds the control of water level, water level is too high pours steam turbine or water level too low damage downstream feed pump in prevention, utilize steam superheat to greatest extent, adopt built-in exhausting equipment, discharge in time and condense the incondensable gas in equipment, avoid corrosion, built-in exhausting equipment condenses except the incondensable gas of equipment except discharging in time, steam can also be guided to flow in certain direction, deflector is coordinated to use, optimize heat transfer effect。
