Description
Technical field
The utility model relates to the device improving warm air flow direction and distribution, and particularly a kind of improvement prevents the device of warm air flow direction and distribution in heat-transfer pipe deformation heat treating processes.
Background technology
When large heat exchanger carries out tube sheet and seal head girth thermal treatment, in order to prevent the heat-transfer pipe in interchanger from producing pit, in the cartridge bore when thermal treatment near tube sheet, pass into the warm air of certain flow and certain temperature.The conduit that ventilation installation connect is put into inner barrel by the cartridge bore near tube sheet, and after the warm air in conduit passes into, in cylindrical shell, air flowing is uneven, and causes certain damage to heat-transfer pipe when warm air directly blows on heat-transfer pipe.
Utility model content
The purpose of this utility model is to provide a kind of device improving warm air flow direction and distribution, safe and reliable, and convenient disassembly is quick, and can improve the thermal cycling in cylindrical shell, uniformity of temperature profile also protects heat-transfer pipe injury-free.
In order to realize above object, the utility model is achieved through the following technical solutions:
Improve a device for warm air flow direction and distribution, be characterized in, comprise:
Vent-pipe, its one end connects outside warm air;
Air plate, it is arranged on vent-pipe the other end position;
Keep out the wind parts, and its connection is arranged on air plate, for blocking the warm air be perforated through from air plate.
A large nozzle is provided with on the barrel of described vent-pipe and near air plate position.
Described air plate surface uniform is distributed with several apertures, makes described warm air blow to vent-pipe outside via aperture.
The described parts that keep out the wind comprise:
Web member, its one end is vertically set on described air plate, and the other end is extended on outside air plate;
Windsheild, it is connected with the web plate the other end.
The thickness of described windsheild from periphery to center thickeies gradually, and the distance inside described windsheild and between air plate is successively decreased from outside to inside successively.
The utility model compared with prior art, has the following advantages:
The utility model is safe and reliable, and convenient disassembly is quick, and can improve the thermal cycling in cylindrical shell, uniformity of temperature profile also protects heat-transfer pipe injury-free.
Accompanying drawing explanation
Fig. 1 is a kind of front view improving the device of warm air flow direction and distribution of the utility model;
Fig. 2 is a kind of side-view improving the device of warm air flow direction and distribution of the utility model;
Fig. 3 is that the utility model keeps out the wind the structural representation of parts;
Fig. 4 is the structural representation of the utility model air plate.
Embodiment
Below in conjunction with accompanying drawing, by describing a preferably specific embodiment in detail, the utility model is further elaborated.
As shown in Figure 1, 2, a kind of device improving warm air flow direction and distribution, comprises: vent-pipe 4, and its one end connects outside warm air; Air plate 3, it is welded on vent-pipe 4 the other end position; Keep out the wind parts 1, and its connection is arranged on air plate 3, for blocking the warm air be perforated through from air plate 3.
A large nozzle 41 is provided with on the barrel of described vent-pipe 4 and near air plate 3 position.
As shown in Figure 4, above-mentioned air plate 3 surface has the aperture 31 that several diameters are Φ f on different diameter of phi a, Φ b, Φ c, Φ d, makes warm air blow to vent-pipe 4 via aperture 31 outside.
As shown in Figure 3, the above-mentioned parts that keep out the wind comprise: web member 11, and its one end is provided with screw thread L, and are vertically set on air plate 3 by nut 2, and the other end is extended on outside air plate 3; Windsheild 12, it is connected with the other end of web plate 11.
The thickness of above-mentioned windsheild 12 from periphery to center thickeies gradually, and the distance inside windsheild 12 and between air plate 3 is successively decreased from outside to inside successively.
During thermal treatment, be connected with the conduit passing into warm air by the vent-pipe 4 of this device, the large nozzle 41 of windsheild 12, air plate 3 and vent-pipe 4 all stretches into inner barrel, during assembling, windsheild 12 is towards the heat-transfer pipe in cylindrical shell, and large nozzle 41 is towards tube sheet side.
During thermal treatment, warm air flows through vent-pipe 4 by conduit, and a part of warm air blows on tube sheet by the large nozzle 41 on vent-pipe 4, and another part warm air flows out via air plate 3.The gas flow direction of this kind of mode and the thermal cycling that can improve in cylindrical shell that distributes, uniformity of temperature profile, windsheild can protect heat-transfer pipe injury-free simultaneously.
In sum, a kind of device improving warm air flow direction and distribution of the utility model, safe and reliable, convenient disassembly is quick, and can improve the thermal cycling in cylindrical shell, uniformity of temperature profile also protects heat-transfer pipe injury-free.
Although content of the present utility model has done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple amendment of the present utility model and substitute will be all apparent.Therefore, protection domain of the present utility model should be limited to the appended claims.
