Abstract
The utility model discloses a kind of finned steam air heater, comprising: swivel joint, reinforcement, fixed frame and heat-exchanging component, heat-exchanging component is corrugated plate shape aluminium flake and stainless steel tube; The punching press of corrugated plate shape aluminium flake forms stretchable holes; Corrugated plate shape aluminium flake is through on stainless steel tube by stretchable holes, and last expanded joint is fixing forms heat-exchanging component; Heat-exchanging component is welded on framework, and fixes with reinforcement; Heat-exchanging component after fixing is arranged on the fixed frame that bearing is housed by pipeline, outside pipeline, swivel joint is housed.It is combined closely between stainless-steel pipe and corrugated plate shape aluminium flake, and heat transfer coefficient is high; This multilayer corrugated tabular aluminium flake area of dissipation is large simultaneously, heat exchange efficiency is high; Overall structure windage is little, rigidity is large; Can not vibrate in steam air heater rotary course, bite.
Description
Technical field
The utility model relates to a kind of steam air heater, particularly relates to a kind of finned steam air heater.
Background technology
Coal-fired boiler in thermal power plant will heat the primary and secondary air entering air preheater to prevent low-temperature corrosion of air preheater and stifled ash winter, usually adopts steam air heater to come to heat to primary and secondary air.Performance major embodiment two point of steam air heater: one, steam air heater body construction windage is the smaller the better; Two, steam air heater body heat exchange area in limited space, air channel is enough large, and heat transfer rate is high; Three, steam air heater entirety has very large rigidity.
Steam air heater conventional in the market has various structures form, each pluses and minuses of having oneself by oneself.The problem having that windage is large, heat transfer rate is little and leak in various degree in actual applications.Therefore need a kind of new steam air heater structure to make up above-mentioned drawback.
Utility model content
The purpose of this utility model is to provide a kind of finned steam air heater, solve the technical problem that windage is large, heat transfer rate is little and leak.
For achieving the above object, the utility model proposes a kind of finned steam air heater, comprising: swivel joint, reinforcement, fixed frame and heat-exchanging component, heat-exchanging component is corrugated plate shape aluminium flake and stainless steel tube; The punching press of corrugated plate shape aluminium flake forms stretchable holes; Corrugated plate shape aluminium flake is through on stainless steel tube by stretchable holes, and last expanded joint is fixing forms heat-exchanging component; Heat-exchanging component is welded on framework, and fixes with reinforcement; Heat-exchanging component after fixing is arranged on the fixed frame that bearing is housed by pipeline, outside pipeline, swivel joint is housed.
Further, the spacing between multilayer corrugated tabular aluminium flake is 4 ~ 5mm.
Further, the stretchable holes internal diameter of corrugated plate shape aluminium flake and the external diameter of stainless steel tube adapt.
Compared with prior art the utility model has following characteristics and beneficial effect:
Combine closely between stainless-steel pipe and corrugated plate shape aluminium flake in steam air heater of the present utility model, heat transfer coefficient is high; This multilayer corrugated tabular aluminium flake area of dissipation is large simultaneously, heat exchange efficiency is high; Overall structure windage is little, rigidity is large; Can not vibrate in steam air heater rotary course, bite.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in more detail.
Fig. 1 is the overall structure figure of finned steam air heater;
Fig. 2 position heat-exchanging component bulk junction composition;
Fig. 3 is the schematic diagram of corrugated plate shape aluminium flake punching;
Fig. 4 is the schematic diagram of corrugated plate shape aluminium flake and stainless steel tube expanded joint;
Reference numeral:
1-corrugated plate shape aluminium flake, 2-stainless steel tube, 3-swivel joint, 4-reinforcement, 5-fixed frame.
Detailed description of the invention
As shown in Figure 3, first corrugated plate shape flake aluminum is stamped out stretchable holes as shown in the figure.As shown in Figure 4, be then through on stainless steel tube 2 by corrugated plate shape aluminium flake 1, design different aluminium flake quantity as required, complete rear structure as shown in Figure 2; Finally adopt expanding joint process, even if stainless steel tube external diameter increases, itself and aluminium flake are firmly combined.As shown in Figure 3, stretchable holes has certain height, and object is that bond strength strengthens simultaneously in order to the bonded area of aluminium flake guarantee and pipe is enough large.
As shown in Figure 1, the heat-exchanging component be made up of corrugated plate shape aluminium flake 1 and stainless steel tube 2 is welded on framework and forms an entirety, fixes with reinforcement 4 simultaneously.This structural rigidity is large, the defect such as pipeline can not be caused to sink, bending, avoids the damage of pipe and the dielectric leakage that causes.
Heat-exchanging component is arranged on by pipeline and is equipped with on the fixed frame 5 of bearing, and swivel joint 3 is housed outside pipeline.Such heat-exchanging component rotates freely in framework 5, because its rigidity is large, therefore can not vibrate.This Novel fin steam air heater device heat exchange efficiency traditional heat exchangers more in the past improves greatly, and windage is little simultaneously, decreases the loss of blower fan energy.
Above-mentioned embodiment is not to restriction of the present utility model; the utility model is also not limited in above-mentioned citing; the change that those skilled in the art make within the scope of the technical solution of the utility model, remodeling, interpolation or replacement, also all belong to protection domain of the present utility model.
