Technique effect of the present utility model is: it has following characteristics:
1, adopt vortex type rotation blower fan, noise is low, vibrate for a short time, and operation is quiet, does not have friction relatively, high life, and blast is moderate, and air quantity is stablized.
2, full embedding structure, do not have ignite, explode, the worry of leakage, volume is little, and is in light weight, easy to install, need not safeguard, safe and reliable to operation.
3, control section adopts the contactless chemical control systems of original paper such as controllable silicon solid-state relay, does not produce spark, do not have ignite, the worry of ignition, contact sintering, longer service life is of a specified duration.
4, have oil separating device, even a large amount of leakage of oils of generator also can not influence the operation of blower fan.
The advantage that the structure of this blower fan in contrast to magnetic transmission blower fan is simple in structure, and volume is little, no easily damaged parts, easy for installation, and rate of fault is low, and Maintenance free is durable in use.

Fig. 2 cuts open structural representation for the office of the utility model mode of execution two.
Embodiment
Mode of execution one:
As shown in Figure 1, the hydrogen circulation fan of present embodiment, comprise support 1, control gear 2 (referring to Fig. 2), blower fan 3 and be provided with into and out of the air port 5,6 blower fan cylinder 4, described blower fan cylinder 4 is a cylindrical body, and its top is provided with cylinder top cover 7, and the bottom is provided with sewage draining exit 8,5,6 upper and lower parts of being located at its outer wall respectively into and out of the air port of blower fan cylinder 4, described blower fan 3 is a Cyclone wind motor, and blower fan 3 is axially fixed in the blower fan cylinder 4, and its blade part is positioned at into and out of the air port 5,6 of blower fan cylinder 4.
Described blower fan cylinder 4 is provided with observation window 9 in the bottom.
Mode of execution two:
As shown in Figure 2, different with mode of execution one is, it comprises that also wall is provided with into, outlet 11,12 separator 10, separator 10 is a cylindrical body, its top is provided with separator top cover 13, the bottom is provided with sewage draining exit 8, the middle part is provided with cyclone separator 14 in the separator 10, cyclone separator 14 is made of circular filter cylinder 15 and the cyclone blade 16 that is arranged in filter cylinder 15 outer wall bottoms, filter cylinder 15 is built-in with filter core, 10 of filter cylinder 15 tops and separators are provided with toroidal membrane 17, filter cylinder 15 is fixing with separator 10 by dividing plate 17, the import 11 of separator 10 is located between dividing plate 17 and the cyclone blade 16, and the outlet 12 of separator 10 is located at dividing plate 17 tops and is connected with the intake grill 5 of blower fan cylinder 4.
Described separator 10 is provided with observation window 9 in the bottom.
Hydrogen circulation fan of the present utility model is mainly used in the hydrogen cooled generator hydrogen desiccation circulatory system, effect is to provide power for the circulation of generator hydrogen desiccation, when generator operation, strengthen the drying cycles amount of hydrogen, thereby improve the efficient of hydrogen desiccation, when the generator stall, keep the drying cycles of hydrogen, make to keep lower humidity in the generator.But and the oil in the filtering hydrogen and oil vapor, dust, impurity etc., protection equipment thereafter is not subjected to dust and oil pollution, thereby reduces cleaning, the maintenance work of equipment thereafter in a large number.For equipment such as adsorption type hydrogen exsiccator and hydrogen humidity on-line monitoring instrument, has excellent protective action especially.
The utility model adopts a kind of blower fan of vortex type structure, and this blower fan has characteristics such as volume is little, flow is big, and blast is moderate, the most important thing is that this blower fan does not have relative friction, need not oil lubrication, and be fit to be built in work in the seal container, can not cause any pollution hydrogen.
The blower fan embedding structure has been adopted in the utility model design.We know that the mixed gas that does not have the explosibility burning under the normal condition in the generator exists, even also do not have (by CO behind row's hydrogen
2Replaced).Therefore internal fan itself needn't be considered explosion-proof problem, and its Security is secure.
1. remove functional oil:
The hydrogen that generator comes at first enters oily hydrogen separator 10, in the oil hydrogen separator 10 cyclone separator 14 is arranged, the oil of vapour-liquid shape can be separated through centrifugal action with hydrogen, form fluid oil and be deposited on separator 10 foots downwards, can discharge (liquid level in the separator 10 can be observed out by the liquid level form) by separator 10 sewage draining exits 8, a small amount of steam state oil is with the filter layer of mixed airflow in cyclone separator 10 middle part filter cylinders 15 of hydrogen, this filter layer has adopted has strong adsorptivity and can be from clean filtering material to oil, can be with the oil gas in the hydrogen, the disposable filtering of impurity such as dust, absorption oil gas reach a certain amount of after, can form fluid oil flows down, make filter core from clean, non-maintaining.Simultaneously, this filter layer has high porosity, and its windage is very little, hydrogen be easy to by, guaranteed that hydrogen can pass through filter layer with enough big flow.Purified hydrogen after the process filtering layer filters enters in the blower fan cylinder 4 and boosts.
2. force the hydrogen recycle function:
Hydrogen is in blower fan cylinder 4, boosted by the running of built-in vortex type rotation blower fan, make the front and back of blower fan 3 produce leeway about the most about 12Kpa, under the effect of this difference force, hydrogen is circulated in the pipeline of generator between air port 5,6 at blower fan 3, thereby form the drying cycles of hydrogen.
