Description
Technical Field
The utility model relates to the technical field of boiler heating surfaces, in particular to a karman vortex street vibration-proof device.
Background
In some domestic projects, the acoustic resonance phenomenon of the karman vortex street occurs when the boiler operates. Through analysis and judgment, the width of a heating channel of the boiler is generally wide, the flow rate of flue gas is high, the vortex street acoustic resonance phenomenon is easy to occur, the heating surface pipe system in the boiler is damaged, and the potential safety hazard is high.
Disclosure of Invention
In order to solve the problem that the acoustic resonance phenomenon of the karman vortex street is easy to occur in the heated channel of the existing boiler, the utility model provides a karman vortex street vibration-proof device which can effectively eliminate the acoustic resonance phenomenon of the boiler and ensure the safety and the stability of the operation of the boiler.
The technical scheme is as follows: the utility model provides a karman vortex street anti-vibration device, its includes the passageway of being heated that the flue backplate is constituteed, install the heating surface piping in the passageway of being heated, the heating surface piping both ends are passed through the pipe clamp and are connected the flue backplate is inboard, its characterized in that, install the passageway baffle of taking the mesh in the passageway of being heated, the passageway baffle sets up between two adjacent rows of heating surface piping, comb plate and last U-shaped bolt are installed to passageway baffle top both sides, go up comb plate direct support in just not weld on the first layer pipe in upper end of heating surface piping, go up U-shaped bolt with the first layer pipe in upper end of heating surface piping is fixed.
The heat exchanger is further characterized in that lower comb plates and lower U-shaped bolts are arranged on two sides of the bottom of the channel partition plate, the lower comb plates are supported on a first layer of tubes at the lower end of the heating surface piping system, and the lower U-shaped bolts are fixed with the first layer of tubes at the lower end of the heating surface piping system
The upper comb plate and the lower comb plate are symmetrically welded on two sides of the channel partition plate respectively;
the upper U-shaped bolt and the lower U-shaped bolt are arranged on two sides of the channel partition plate in a staggered mode;
the channel partition plate comprises two blocks which are arranged side by side at intervals;
the number of the upper comb plate and the upper U-shaped bolts is more than that of the lower comb plate and the lower U-shaped bolts.
After the utility model is adopted, the channel clapboard arranged between two adjacent rows of heating surface pipe systems is added in the heating surface pipe, the upper end of the channel clapboard is positioned and supported by the upper comb plate, the upper U-shaped bolt is fixed, the existence of the channel clapboard changes the inherent acoustic frequency in the original heating channel, prevents the karman vortex street and effectively avoids the resonance phenomenon; furthermore, a lower comb plate and a lower U-shaped bolt are arranged at the lower end of the channel partition plate and used for preventing shaking, ensuring reliable installation of the channel partition plate and ensuring safe and stable operation of the boiler.

Detailed Description
Referring to fig. 1 to 5, a karman vortex street vibration isolator comprises a heated channel 2 formed by flue protection plates 1, a heated surface piping system 3 is installed in the heated channel 2, two ends of the heated surface piping system 3 are connected with the inner side of the flue protection plates 1 through pipe clamps 4, a channel partition plate 5 with meshes is installed in the heated channel 2, the channel partition plate 5 is arranged between two adjacent rows of the heated surface piping systems 3, a comb plate 6 and an upper U-shaped bolt 7 are installed on two sides of the top of the channel partition plate 5, the upper comb plate 6 is directly supported on a first layer of pipes at the upper end of the heated surface piping system 3 and is not welded for suspension support, meanwhile, deformation of steel plates caused by fixing of the upper U-shaped bolt 7 can be avoided, the upper U-shaped bolt 7 is matched with an upper nut 8 to be fixed with the first layer of pipes at the upper end of the heated surface piping systems 3, assembly and disassembly are convenient, and free expansion of the piping systems is not influenced.
The two sides of the bottom of the channel partition plate 5 are provided with a lower comb plate 9 and a lower U-shaped bolt 10, the lower comb plate 9 is supported on the first layer of pipe at the lower end of the heating surface piping system 3, the lower U-shaped bolt 10 is fixed with the first layer of pipe at the lower end of the heating surface piping system 3, in general arrangement, the number of the upper comb plate 6 and the upper U-shaped bolt 7 is more than that of the lower comb plate 9 and the lower U-shaped bolt 10, the upper end is used for fixing and supporting, the lower end is only shaken till now, the number can be a little less, and the purpose of saving materials can be achieved. The upper comb plate 6 and the lower comb plate 9 are of asymmetric construction.
Go up comb-shaped plate 6 and comb-shaped plate 9 respectively the symmetric welding in 5 both sides of passageway baffle, guaranteed the stability of support, go up U-shaped bolt 7 and stagger with lower U-shaped bolt 10 and arrange in 5 both sides of passageway baffle for dodge each other, can realize reliably fixing simultaneously.
In this embodiment, the channel partition 5 includes two blocks arranged side by side at intervals, and the specific number and size can be adjusted according to the size of different chambers, so as to be suitable for different furnace types with different capacities.
