Detailed description of the invention
Below in conjunction with diagram, the utility model is described in detail, Fig. 1 is the front view of film-type wall-type vacuum hot water boiler, as shown in the figure, the vacuum hot water boiler related in the utility model is primarily of upper part and lower part composition, top is divided into heat-exchanger rig, bottom is divided into heater, by upper water box, and burner hearth and lower header composition.
As shown in the figure, 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.
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, the temperature difference of formula according to the water of boiler water inlet pipe and water outlet pipe is put in the arrangement of Tube Sheet of Heat Exchanger 9, the rocking of Tube Sheet of Heat Exchanger 9 caused due to water flow velocity adopts fixed head 7 to be fixed, cold water is introduced after Tube Sheet of Heat Exchanger 9 by front water chamber 2, then the water after hydroecium 11 exports heating later, water inlet tubing string 201 and water outlet tubing string 111 place are equipped with pressure-temperature sensor.
The all interior arrangements of large young pathbreaker of U-shaped housing 5 load just, unsuitable excessive.
The lower part of vacuum hot water boiler is by upper water box 3, and burner hearth and lower header 1 form, and upper water box 3 centre position has a water level observation hole 29 and is used for observing the water level in water tank, has a lower header drain pipe 26 bottom lower header, is used for discharging the water in water tank.
Fig. 4 is the profile of burner hearth in Fig. 1, burner hearth is a cuboid cavity, be positioned in the middle of upper water box 3 and lower header 1, burner hearth porch is provided with burner jockey 12, be used for install combustion device, burner hearth inside circumference by membrane wall around, membrane wall can be close arranging pipe membrane wall, also can be extended surface tube membrane wall.As shown in Figure 2, two of burner hearth porch light pipes are curved and allow pipe by conveniently install combustion device, form two and allow pipe 13.Meanwhile, in order to reduce thermal loss in burner hearth and flue gas leaks, have flue gas shrouding 25 allowing between pipe 13 and membrane wall, the cut-out in the middle of flue gas shrouding 25 is equal to the size of burner nozzle.
Membrane wall is around the surrounding being vertically arranged in burner hearth, and membrane wall is symmetrical many backhauls membrane wall, and with the center line symmetry arrangement of burner hearth, can be 2-5 backhaul, be good with three backhauls.
For three backhauls, in three backhaul membrane walls, the first backhaul is due to the membrane wall I 14 of inlet face, is positioned at the membrane wall II 16 of cuboid burner hearth two sides and surrounds with the membrane wall V 20 of inlet face opposite face; Second backhaul is folded by membrane wall II 16 and membrane wall III 17 and forms; 3rd backhaul both sides are folded by membrane wall III 17 and membrane wall IV 18 and membrane wall V 20 and membrane wall VI 28 fold and form, wherein membrane wall VI 28 interposition is equipped with some light pipes and does not weld in flakes, relative with exhanst gas outlet device 22, in burner hearth, the discharge of flue gas provides passage.The width of two return is more than or equal to the width of three backhauls.Exhanst gas outlet is provided with at the end of each backhaul.
Bottom the left and right sides of the in the end burner hearth of a backhaul, steam trap connection 27 is installed, is used for the condensed water collected because heat exchange produces on membrane wall.
The flue gas that burner combustion produces carries out heat exchange along membrane wall flowing with the heat medium water in membrane wall, then discharges from outlet 22.
The design of all membrane walls is all with the sectional elevation symmetrical placement of burner hearth center line above, and this symmetric design makes the flue gas in burner hearth spread to both sides, uniform force, and heat transfer evenly, reduces energy loss.
