Abstract
The utility model discloses a heater for an expansion heating network, in particular to a U-shaped tubular steam-water heat exchanger, which belongs to heat exchanging devices. The heater for the expansion heating network comprises a tube case, a tube plate, a casing, a U-shaped tube bundle, a steam inlet-outlet and a heated water inlet-outlet, and is characterized in that a diameter enlarging section is arranged at a connecting position of the casing and the tube plate, a horizontal semicircular drain well is mounted on the outer side of the bottom portion of the casing, the casing is communicated with the drain well through a connecting hole, and a condensed water discharging opening is arranged at the bottom portion of the drain well. The heat exchanger adopts the horizontal drain well integrated with the heat exchanger, thereby enlarging effective heat exchanging area, enhancing heat exchanging efficiency, weakening shock of steam to the tube bundle and enabling a rolling wheel chute to be assembled easily by employing the diameter enlarging section at the connecting position of the tube plate and the casing. The heat exchanger has the advantages of reasonable and compact structure, high efficiency, low cost, convenient maintenance and the like.
Description
Technical field
The utility model belongs to heat-exchange apparatus, particularly U type tubular type vapor-water heat exchanger.
Background technology
The carbonated drink heat exchangers for district heating that is widely used in steam power plant, urban district heating system at present is a fixed tube-sheet exchanger.This heat exchanger shortcoming is obvious: heat exchange efficiency is low, production process is more loaded down with trivial details, heat exchanger tube is bearing the bigger stress that self produces in the equipment course of work, there is not hydrophobic well below the heat exchangers for district heating that is one of principal element of heat exchanger tube generation fracture, has, heat exchange weak effect and fluctuation of service, be furnished with split type hydrophobic well below the heat exchangers for district heating that has, so just caused shortcomings such as equipment occupation space is big, high material consumption, manufacturing cost height.
The utility model content
In order to reduce impact, the increase heat exchange area raising heat exchange efficiency of steam to tube bank, the purpose of this utility model provides a kind of expanding type heat exchangers for district heating, and this expanding type heat exchangers for district heating is the heat exchange efficiency height not only, and has alleviated the impact of steam to tube bank.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of expanding type heat exchangers for district heating, comprise bobbin carriage, tube sheet, housing, the tube bank of U type, water entrance is imported and exported, is heated to steam, it is characterized in that: described housing and tube sheet junction are extension diameter section, the hydrophobic well of horizontal semicircle is equipped with in the housing bottom outside, housing has connecting hole to communicate with hydrophobic well, and hydrophobic bottom has condensate drain outlet.
Between described housing bottom and the tube bank of U type the roller slideway is housed.
In the utility model because at housing and the interbank roller slideway that is provided with, the time saving and energy saving damage of having avoided tube bank when assembling, and can protect support to restrain.Hydrophobic well adopts structure horizontal and the heat exchanger Contiuum type, and the position that not only takes up room is little, is easy to install, and connects and stablizes, and help stable, the security of stable level and equipment operation, has improved heat transfer efficiency.Adopted extension diameter section at tube sheet and housing junction, steam inlet place circulation area is increased, steam flow rate sharply diminishes, and greatly alleviates the impact of exchange heat pipe, has eliminated the risk factor of tube vibration and disconnected pipe, makes heat exchanger tube avoid damage.Adopt clad tubesheet, make the welding that has formed metal of the same race between pipe joint and the tube sheet, and metal of the same race is compared with dissimilar metal and is easier to welding, has guaranteed welding quality.
The beneficial effects of the utility model are owing to adopted horizontal and the hydrophobic well of heat exchanger Contiuum type to increase that effective heat exchange area improves heat exchange efficiency, tube sheet has adopted extension diameter section to weaken the impact of steam to restraining with the housing junction, the roller slideway is convenient to assembling, makes to the utlity model has advantages such as compactness rational in infrastructure, efficient height, cost are low, easy to maintenance.
