Description
Technical field
The utility model relates to a kind of vacuum hot water boiler, particularly a kind of heat-exchanger rig of vacuum hot water boiler.
Background technology
The full name of vacuum boiler is called phase change vacuum boiler.Vacuum boiler is the vacuum environment forming a negative pressure at the furnace interior closed, in body, fill heat medium water, by burning or alternate manner heating heat medium water, then is evaporated by heat medium water, is condensed on heat exchanger, then heated the water needing heating by heat exchanger.Vacuum boiler, by vacuumizing, forms the environment under low pressure that does not almost have air, then utilizes water under low pressure (lower than atmospheric pressure) low-temperature boiling generation steam, the principle work exported by heat by carbonated drink condensation heat transfer mode.Heat medium water in vacuum boiler is through the high purity water of the specially treated such as deoxidation, scale removal, once fill before dispatching from the factory, in the circulation of unit enclose inside (vaporization → condensation → vaporization) during use, do not increased, do not reduce, do not need to supplement or change within unit service life.
The heat-exchanger rig of vacuum hot water boiler is the core component of boiler, in heat-exchanger rig, form low pressure, carries out heat exchange, and its air-tightness security is the basic guarantee ensureing vacuum hot water boiler trouble-free operation.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of heat-exchanger rig of vacuum hot water boiler, comprise front water chamber 2, U-shaped housing 5 and rear hydroecium 11, and the water inlet tubing string 201 be arranged on front water chamber 2 and rear hydroecium 11 and water outlet tubing string 111, upper cover plate is had in U-shaped housing 5, the forward and backward tube sheet 10 of heat exchanger is placed on upper cover plate, and Tube Sheet of Heat Exchanger 9 is arranged on the forward and backward tube sheet 10 of described heat exchanger, and described U-shaped housing 5 has exhaust tube 23.
Preferably, Tube Sheet of Heat Exchanger 9 described in fixed head 7 is also had to be fixed.
Preferably, U-shaped housing 5 there is blasting piece device 6.
Preferably, hydroecium steam trap connection 24 is connected with in the bottom of Tube Sheet of Heat Exchanger 9.
Preferably, water inlet tubing string 201 and water outlet tubing string 111 place are equipped with pressure-temperature sensor.
Above-mentioned heat-exchanger rig; vacuum hot water boiler is run more steady; solve the problem that the Tube Sheet of Heat Exchanger caused due to water flow velocity is easy to rock; provide overvoltage protection; and the unnecessary condensed water in heat exchange is rationally discharged; the temperature and pressure imported and exported rationally is monitored, adjustment heat exchanger types can be required according to different boiler, be easy to dismounting.

Detailed description of the invention
Below in conjunction with diagram, the utility model is described in detail.Fig. 1 is the front view of vacuum hot water boiler, and as shown in the figure, the vacuum hot water boiler related in the utility model is primarily of upper part and lower part composition, and top is divided into heat-exchanger rig, and bottom is divided into heater, by upper water box, and burner hearth and lower header composition.
As depicted in figs. 1 and 2, the heat-exchanger rig of the upper part in vacuum hot water boiler mainly comprises front water chamber 2, U-shaped housing 5 and rear hydroecium 11, and the water inlet tubing string 201 be arranged on front water chamber 2 and rear hydroecium 11 and water outlet tubing string 111.
Can see in fig. 2 and U-shaped housing is provided with exhaust tube 23, be used for vacuumizing in heat-exchanger rig, make to form negative pressure in U-shaped housing 5, simultaneously in order to the consideration of safety factor, U-shaped housing has blasting piece device 6, play the effect of pressure release when pressure exceeds standard.Blasting piece device 6 forms primarily of three parts, be respectively orifice plate sheet, rupture pressure disc and sharp object composition, its aperture plate sheet is a circular piece made by on-deformable material, circular piece has some passages, rupture pressure disc is placed on the top of orifice plate sheet, place very near with rupture pressure disc above rupture pressure disc is equipped with a sharp object, and when pressure overpressure malleation in U-shaped housing, rupture pressure disc can protuberance slightly, now sharp object can puncture rupture pressure disc at once, plays the effect of pressure release.
Be connected with hydroecium steam trap connection 24 in the bottom of Tube Sheet of Heat Exchanger, be used for collecting condensed water.
The inside of U-shaped housing, the forward and backward tube sheet 10 of heat exchanger is placed on upper cover plate, Tube Sheet of Heat Exchanger 9 is arranged on the forward and backward tube sheet of heat exchanger, be easy to dismounting, the type of arrangement of Tube Sheet of Heat Exchanger can be adjusted as required, the arrangement formula of putting of Tube Sheet of Heat Exchanger 9 determines according to the temperature difference of the water of boiler water inlet pipe and water outlet pipe, rocking of the Tube Sheet of Heat Exchanger 9 adopting fixed head 7 fixing to cause due to water flow velocity, cold water is introduced after Tube Sheet of Heat Exchanger 9 by front water chamber 2, export through hydroecium 11 later, water inlet tubing string 201 and water outlet tubing string 111 place are equipped with pressure-temperature sensor again.
The all interior arrangements of large young pathbreaker of U-shaped housing 5 load just, unsuitable excessive.
Be more than one of embodiment of the present utility model, for those skilled in the art, do not spend performing creative labour, multiple change can be done in the basis of above-described embodiment, can the purpose of this utility model be realized equally.But this change obviously should in the protection domain of claims of the present utility model.
