Description
Technical field
The utility model relates to a kind of built-in deaerator constant speed shower nozzle, belongs to mechanical field.
Background technology
Owing to generally adopting rotating-film deaerator for petrochemical industry boiler, the supporting oxygen-eliminating device generally using of medium temperature and medium pressure station boiler at present, because rotating-film deaerator is because of self reason, huge structure, takes up room large, and cost is high, cause the waste in the energy and space, and built-in deaerator nozzle structure is single, ability is little, and atomizing effect and constant velocity characteristics are undesirable, heat transfer efficiency is low, thereby has affected oxygen-eliminating device performance.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of volume little, the built-in deaerator constant speed shower nozzle that atomizing effect is good.
Built-in deaerator constant speed shower nozzle described in the utility model, comprise tubular nozzle holder, double-screw bolt is established in nozzle holder lower end, double-screw bolt passes successively spaced dish-shaped nozzle piece and spacer, compressing tablet and is fixed on nozzle holder by nut, nozzle holder upper end flange, on nozzle holder outer tube wall, establish spring, nozzle holder is arranged in housing, its internal diameter coordinates with nozzle holder flange place, in nozzle mount pad, establish screen pack, screen pack upper end is arranged on housing upper end by screw.
Between nut and compressing tablet, establish retaining pad.
Operation principle and process:
During work, water inherent filtration net enters in nozzle mount pad, and eject umbrella shape atomization moisture film by dish-shaped nozzle piece, pressing plate pressurized when the supply water yield is large, spring is compressed, under dish-like nozzle piece is whole, stretch, reach maximum stream flow, when flow reduces, pressing plate pressurized diminishes, under the effect of spring, the working quantity of dish-like nozzle piece reduces, the size of flow is regulated the working quantity of dish-like nozzle piece voluntarily by spring, water enters in multilayer dish nozzle piece gap, under the effect of small pressure difference very, condensate water ejects multilayer moisture film from inside to outside along the radial direction of parallel dish-shaped nozzle piece, under the effect of nozzle lip, moisture film is broken, change and flow to, the final multilayer that forms intermeshes, shape, the 360 degree umbrella shape atomization moisture films that size is desirable, moisture film can not destroy because of changes in flow rate yet, the built-in screen pack of nozzle is not subject to the impact of impurity in water while making work, do not exist seriously stuck, block, wearing and tearing, the failure phenomenons such as leakage, this constant speed shower nozzle and oxygen-eliminating device body without a head support the use, the quantity of dish-like nozzle and size are determined by metered flow and the deaerator nozzle arrangement of deaerated water.
The beneficial effect that the utility model compared with prior art had is:
Built-in deaerator constant speed shower nozzle described in the utility model, volume is little, atomizing effect is good, is not subject to the impact of impurity in water, do not exist seriously stuck, block, wear and tear, the failure phenomenon such as leakage, simply efficient.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment schematic diagram.
In figure: 1, nut; 2, retaining pad; 3, double-screw bolt; 4, pressing plate; 5, spacer; 6, dish-like nozzle piece; 7, nozzle holder; 8, spring; 9, sealing ring; 10, filter; 11, housing; 12, screw.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figure 1, schematic diagram when left-half is work, schematic diagram when right half part is static, built-in deaerator constant speed shower nozzle described in the utility model, comprise tubular nozzle holder 7, double-screw bolt 3 is established in nozzle holder 7 lower ends, double-screw bolt 3 is successively through spaced dish-shaped nozzle piece 6 and spacer 5, compressing tablet 4 is also fixed on nozzle holder 7 by nut 1, nozzle holder 7 upper end flange, on nozzle holder 7 outer tube walls, establish spring 8, nozzle holder 7 is arranged in housing 11, its internal diameter coordinates with nozzle holder 7 flange places, in nozzle mount pad 7, establish screen pack 10, screen pack 10 upper ends are arranged on housing 11 upper ends by screw 12.
Between nut 1 and compressing tablet 4, establish retaining pad 2.
Operation principle and process:
During work, water inherent filtration net 10 enters in nozzle mount pad 7, and eject umbrella shape atomization moisture film by dish-shaped nozzle piece 6, pressing plate 4 pressurizeds when the supply water yield is large, spring 8 is compressed, under dish-like nozzle piece 6 is whole, stretch, reach maximum stream flow, when flow reduces, pressing plate 4 pressurizeds diminish, under the effect of spring 8, the working quantity of dish-like nozzle piece 6 reduces, the size of flow is regulated the working quantity of dish-like nozzle piece 6 voluntarily by spring 8, water enters in multilayer dish nozzle piece 6 gaps, under the effect of small pressure difference very, condensate water ejects multilayer moisture film from inside to outside along the radial direction of parallel dish-shaped nozzle piece 6, under the effect of nozzle lip, moisture film is broken, change and flow to, the final multilayer that forms intermeshes, shape, the 360 degree umbrella shape atomization moisture films that size is desirable, moisture film can not destroy because of changes in flow rate yet, the built-in screen pack 10 of nozzle is not subject to the impact of impurity in water while making work, do not exist seriously stuck, block, wearing and tearing, the failure phenomenons such as leakage, this constant speed shower nozzle and oxygen-eliminating device body without a head support the use, the quantity of dish-like nozzle and size are determined by metered flow and the deaerator nozzle arrangement of deaerated water.
