Abstract
The utility model relates to the field of chemical industry and metallurgy production, and discloses a tile-shaped throttle orifice device for a flash evaporator, comprising a tile-shaped orifice plate, and the tile-shaped orifice plate is provided with a central hole along the axial direction. By using the tile-shaped throttle orifice device, the manufacture, installation and overhauling of the throttling device are easier, and the requirement that the charging rate is increased can be met.
Description
Technical field
The utility model relates to metallurgy, chemical industry technology production field, relates in particular to a kind of watt shape restricting orifice device that is used for flash vessel.
Background technology
High pressure stripping flash tank is a common equipment on the aluminium oxide high pressure stripping production line.In the production run; After being installed in the throttling arrangement throttling on the feed pipe; Make the slip that gets in the flash tank through feed pipe atomize, evaporate rapidly, separate into enriching slurry and indirect steam from the throttling arrangement ejection; Enriching slurry is discharged to next stage flash tank or dilution trap from the bottom, indirect steam is discharged from the top and got into corresponding heat exchanger, thereby the slip pressure and temperature is reduced rapidly.
The flash tank throttling arrangement generally is installed in the feed pipe end; Its aperture is less than pipe diameter; When getting into pipeline and the rate-of flow one through throttling arrangement regularly; Flow velocity through throttling arrangement is bound to greater than the flow velocity of medium in pipeline, therefore can when flowing out throttling arrangement, form the conical jet state.
The feed pipe outlet of flash tank can extend into the center of flash tank.For to the flow velocity that gets into the slip in the flash tank with pressure is controlled and balance, must be at feed pipe port of export installation throttling arrangement, to reach the throttling purpose.The radially sketch map of at present traditional throttling arrangement that is used for flash vessel is as shown in Figure 1; Throttling arrangement is by orifice plate seat 1; Orifice plate 2 is formed; Orifice plate 2 usefulness screws are connected on the orifice plate seat 1, again the throttling arrangement that links together are welded on the suitable position of feed pipe 3 ports of export, are illustrated in figure 2 as the axial cross section sketch map of conventional throttle device.
The shortcoming of traditional throttling arrangement is: the throttling arrangement volume is big, and Heavy Weight is installed in the termination, extracts difficulty when maintenance is changed out; Because orifice plate and orifice plate pedestal are long-pending bigger, corresponding flash tank feed pipe is taken over also very big.Along with improving constantly of stripping unit inlet amount, require feed pipe to take over and further become big.But take over and infinitely to amplify according to the restriction feed pipe of flange standard; As according to GB/T9115.2-2000 flange standard; The maximum nominal diameter of the flange of PN5.0Mpa is DN600; And the stripping inlet amount reaches 850m3/h when above, and flash tank feed pipe specification is increased to Ф 426 * 16, requires the flash tank feed pipe to take over and is increased to more than the DN800.Therefore traditional flash tank can not meet the demands with the restricting orifice device.
The utility model content
The technical problem that (one) will solve
The technical problem that the utility model solved is: provide a kind of volume little, and in light weight and satisfy the big throttling arrangement of inlet amount.
(2) technical scheme
In order to achieve the above object, the utility model provides a kind of watt shape restricting orifice device that is used for flash vessel, comprise a watt shape orifice plate, said watt of shape orifice plate axially is provided with center drilling along it.
Wherein, said watt of shape orifice plate processed by wear-resisting alloy steel.
Wherein, the thickness of said watt of shape orifice plate is 20~50mm.
Wherein, the center drilling of said watt of shape orifice plate is shaped as circle, ellipse or rectangle.
(3) beneficial effect
The technical scheme of the utility model has following advantage: manufacturing, installation, the maintenance of watt shape restricting orifice device of the utility model all are easy to, and can satisfy the requirement that inlet amount increases.
Description of drawings
Fig. 1 is the longitudinal section view of the throttling arrangement of prior art;
Fig. 2 is the axial, cross-sectional view of the throttling arrangement of prior art;
Fig. 3 is the longitudinal section view of watt shape restricting orifice device that is used for flash vessel of the utility model;
Fig. 4 is the axial, cross-sectional view of watt shape restricting orifice device that is used for flash vessel of the utility model.
The specific embodiment
In order to be illustrated more clearly in the technical scheme of the utility model, be further described below in conjunction with accompanying drawing.
Shown in Fig. 2-3; Watt shape restricting orifice schematic representation of apparatus that is used for flash vessel for the utility model comprises a watt of shape orifice plate 4 of being processed by wear-resisting alloy steel, and a watt shape orifice plate 4 axially is provided with center drilling 6 along it; The size of center drilling 6 is calculated according to feed size and is got; Shape can be circle, ellipse or rectangle, and it meets the requirement of corresponding flash tank feed rate, pressure, bore edges pile-up welding hard alloy.The thickness of watt shape orifice plate 4 is generally 20~50mm.Watt shape orifice plate 4 axial lengths can be with center drilling size and Adjusting Shape.
The utility model is used for watt shape restricting orifice device of flash vessel and directly detains the outlet position that is welded in feed pipe 5; Directly watt shape restricting orifice device is sliced off from feed pipe during replacing; Again weld a new watt shape restricting orifice device again, make manufacturing, installation, maintenance become very easy like this, not high to watt shape restricting orifice device required precision yet; Thereby cost-saved, reduce labour intensity.
Use the utility model be used for watt shape restricting orifice device of flash vessel the time; Feed pipe adapter aperture is a bit larger tham feed tube diameter and gets final product; Guarantee feed pipe is extracted out smoothly, like feed pipe Ф 426 * 16, then charging pipe connecting flange specification can be selected the flange of PN5.0Mpa, DN600.
The above only is the embodiment of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model know-why; Can also make some improvement and modification, these improvement and modification also should be regarded as the protection domain of the utility model.
