Abstract
The utility model discloses a direct combustion lithium bromide absorption refrigerator's high pressure generator structure, which is composed of a burner port (3), a front smoke box (1), a front tube sheet (2), a furnace chamber (4), a water tube device (5), a rear tube sheet (6), a rear smoke box (7), a fire tube bundle (8), a cylinder (9), and refrigerant water vapor (10) welded with each other. The utility model is characterized in that the water tube device (5) is directly welded between the furnace chamber (4) and the rear tube sheet (6). The cylinder (10) adopts the structure matched with the special-shaped structure. Adopting the structure, the utility model raises the heat efficiency, protects the smoke box, simplifies the production process, lowers the manufacturing difficulty, enhances the reliability of operation, reduces the structure size, reduces the required quantity of the solution and accelerates the starting speed.
Description
The utility model is the high pressure generator structure about the direct combustion type lithium bromide refrigerator, particularly with the high pressure generator of water, fire tube structure, first backhaul of this high pressure generator is by burner hearth and place a pipe device of stove hall afterbody to constitute, and the fire tube tube bank is adopted in second backhaul.
The general high pressure generator that adopts two kinds of patterns of at present domestic direct-burning type lithium bromide absorption type refrigeration machine.A kind of is the fire tube structure, this structure utilization runs through the burner hearth of whole cylindrical shell as first backhaul, the fire tube tube bank constitutes second backhaul of flue gas, the high pressure generator of this structure is made simple, but volume dotes on greatly, and required solution is big, the startup of unit time is long, the thermal efficiency is low, and furnace flame act directly on the back smoke box on, smoke box is burnt out easily.Another is the extreme misery tubular construction; just on the basis of first kind of pattern; in the space that back smoke box and back tube plate surround, added the water screen tube structure; though protected back smoke box, water cooling tube is made difficulty, takes over complicated; and it is concentrated to be easy to generate stress; water-cooling wall is burnt out easily, influences the unit operation reliability, and improves not obvious to the thermal efficiency.
The utility model purpose provides a kind of high pressure generator structure of making the direct-burning type lithium bromide absorption type refrigeration machine simple, that the thermal efficiency is high, volume is little, and it can improve the thermal efficiency and the reliability of operation.
In order to realize the utility model, between as the burner hearth afterbody of first backhaul and smoke box, a pipe device is set, the two ends of pipe device respectively with burner hearth afterbody and back tube sheet welding.
After adopting this structure, owing to be provided with a pipe device at the burner hearth afterbody, this device can stop that furnace flame acts directly on the smoke box of back, has protected back smoke box, has increased operational reliability.Arrange the water pipe that quantity is suitable on the pipe device simultaneously, increased heat transfer area widely, improved the thermal efficiency.Water pipe adopts the straight tube must bending and forming, simplified manufacture craft, pipe device can be assembled back direct and burner hearth and back tube sheet welding separately, reduced manufacture difficulty, the high pressure generator cylindrical shell adopts the polymorphic structure that matches with structure, reduce volume, reduced required solution amount, thereby just accelerated priming speed.
Fig. 1 is the transverse sectional view of an embodiment of the utility model.
Fig. 2 is the longitudinal sectional view of an embodiment of the utility model.
Below in conjunction with description of drawings the utility model.
As shown in Figure 2, earlier pipe device 5, burner hearth 4 and port 3 assembly weldings are good, then that assembly welding is good assembly welds mutually with back tube sheet 6, selected back tube sheet is a benchmark, utilize three fire tubes in the fire tube tube bank 8 to determine the front tube sheet position, port 3 and front tube sheet 2 welding, again fire tube is restrained the welding of 8 polings, then welding mutually with the front and back tube sheet with the generator cylindrical shell 9 that internal structure matches as shown in Figure 1, on the front smoke box 4 welding front tube sheets 1, back smoke box 7 is welded on the back tube sheet 6, on water as refrigerant steamdrum 10 welding high pressure generator cylindrical shells 9 relevant positions.
Claims (3)
1, a kind of high pressure generator of direct-burning type lithium bromide absorption type refrigeration machine, be welded to form by front tube sheet (2), front smoke box (1), port (3), burner hearth (4), pipe device (5), back tube sheet (6), back smoke box (7), fire tube tube bank (8), cylindrical shell (9) and water as refrigerant steamdrum (10) etc., it is characterized in that between burner hearth (4) and back tube sheet (6), being provided with a pipe device (5).
2, direct-burning type lithium bromide absorption type refrigeration machine high pressure generator according to claim 1 is characterized in that the cross section of pipe device (5) is square, and the water pipe of pipe device (5) both can be horizontally disposed, also can vertically arrange.
3, direct-burning type lithium bromide absorption type refrigeration machine high pressure generator according to claim 1 is characterized in that cylindrical shell (9) adopts the polymorphic structure that matches with internal structure.
