Description
Technical field
The utility model relates to technical field of heat exchange, particularly a kind of heat exchangers for district heating.
Background technology
Surface heater is applied relatively general in thermal power plant, and heat exchangers for district heating heat exchanger tube is U-tube formula, because of metal material and installation process is improper causes heating for multiple times pipe incident of leakage in heating network operation.After heat exchangers for district heating heat exchanger tube transform straight pipe heat exchanger as by U-tube, heat transfer effect is poor, and the problems such as hydrophobic water level is low, the temperature rise of water side is little, thermal effect is poor, badly influence economy and the security of unit heat supply running.
The performance of heat exchangers for district heating heat exchanger depends on structure, at the beginning of heat exchangers for district heating transform straight tube structure as, the design passed in and out for the intake-outlet employing level of heater hydroecium does not add variation, for straight pipe heat exchanger, because outlet pipe is not at hydroecium topmost, the shortcoming of this mode makes to there is large quantity of air in heat exchanger tube and gathers, and can not be full of water in heat exchanger tube, air accumulation can not be discharged.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of heat exchangers for district heating, solve heat exchangers for district heating heat transfer effect poor, the problems such as drain temperature is low, the temperature rise of water side is little, thermal effect is poor, heater heat transfer effect is improved greatly, improves economy and the security of unit heating period simultaneously.
For achieving the above object, the utility model provides following technical scheme: a kind of heat exchangers for district heating, comprise cylindrical shell body, the sidewall of cylindrical shell is provided with water inlet pipe, the top of cylindrical shell is provided with drainpipe, inner barrel tilts to be provided with dividing plate, dividing plate is provided with drain hole, the top of described cylindrical shell is provided with exhaust port, and the bottom in cylindrical shell is pyramidal structure, and cylindrical shell is provided with dewatering outlet in the both sides of sidewall, dewatering outlet place is provided with adjutage, adjutage is provided with water discharging valve, and exhaust port is provided with blast pipe, and blast pipe is provided with drain tap.
Preferably, the top of described cylindrical shell is provided with manhole, and manhole place is hinged with renovates.
Preferably, described in renovate and be provided with rotary handle with manhole place, the end of handle is provided with the baffle plate contacted with manhole, and the place of renovating is provided with rubber washer.
Preferably, the sidewall of described cylindrical shell is provided with and fills nitrogen interface.
Preferably, the bottom of described cylindrical shell is provided with supporting seat.
The beneficial effect of above technical scheme is adopted to be: by transformation heater outlet conduit frame mode, straight pipe type heat exchangers for district heating delivery port is changed the water outlet of into highest portion position by the horizontal water outlet in former middle and upper part, whole heat exchange area is effectively utilized, solve heat exchangers for district heating heat transfer effect poor, the problems such as drain temperature is low, the temperature rise of water side is little, thermal effect is poor, heater heat transfer effect is improved greatly, improves economy and the security of unit heating period simultaneously.
Heat exchangers for district heating hydroecium arranges manhole, during stop production to overhaul, conveniently carries out repair welding or plugging to tube-to-sheet joint place.Heat exchangers for district heating arranges nitrogen filled protection interface, when heat add device stop transport for a long time time, carry out filling nitrogen anticorrosion.Vapour side and the water side of heat exchangers for district heating all arrange dewatering outlet, for stop transport and maintenance time pressure release and drain ponding.Meanwhile, water side hydroecium median septum has drain hole, ensures that top hydroecium drains ponding.Heat exchangers for district heating hydroecium peak is provided with gas vent, for discharging the air in piping during water filling.
