Description
Technical field
The present invention relates to the water intake end support component of inserted component in heat exchanger tube augmentation of heat transfer in the equipment such as a kind of shell-and-tube heat exchanger, heat exchanger and antiscaling, descaling.
Technical background
Along with the development of World Economics, energy shortage becomes the world problem being badly in need of solving, energy-saving and emission-reduction become the key technology solving energy problem, be widely used in the shell-and-tube heat exchanger of the industries such as oil, chemical industry, electric power, metallurgy, pharmacy and machinery, the quality of its heat exchange efficiency directly decides economic benefit and environmental benefit.But the situation of ubiquity fouling in pipe wall of heat exchange pipe, not only cause the increase of flow resistance, and reduce heat exchange efficiency, cause great waste to the energy, the dirt in heat exchanger tube also easily causes underdeposit corrosion, has a strong impact on the safety of equipment.
For the problems referred to above, traditional method shuts down to adopt the method such as mechanical cleaning, Chemical cleaning to clean it, and the waste of the manpower and materials not only caused, also causes the pollution of environment.Owing to shutting down, equipment is cleaned, also can delay production, cause huge economic loss.For the designer that solves the problem is researching and developing always can in non-stop-machine situation, the method and apparatus of online strengthening heat transfer and antis cale.China Patent No. is ZL200520127121.9, and disclose the patent No. that denomination of invention is " rotator type cleaning and heat-transfer enhancing device ", this device is made up of suspension member, rotor, flexible shaft and stay pipe, and two suspension members are separately fixed at the two ends of heat exchanger tube; The outer surface of rotor has scroll, and rotor has centre bore, and flexible shaft is fixed on the suspension member at two ends through the centre bore of rotor.This device has the function of on-line automatic antiscale, scale removal and augmentation of heat transfer.Wherein suspension member is a kind of diversion type self-tightening hanging part, and China Patent No. is 201010184095.9, and it mainly comprises hollow shaft, connecting rod.Brace table and external part, it well can ensure the centering of flexible shaft, but the loss that suspension member is arranged on the heat exchanger tube resistance that heat exchange tube inlet causes is larger, needs to install at the scene fixing, install consuming time more in actual installation.For solving the large problem of suspension member comparison of resistance, Chinese patent 201210067268.8, disclose a kind of low flow-resistance quick-mounting hanger, this suspension member solves the larger problem of entry resistance, but it is in the project installation of reality, this suspension member can only be installed at the scene, can not fit together in processing factory and plug-in part, add on-the-spot installation work-hour, owing to needing shutdown to carry out when installing, the time of shutting down is very limited, and in-site installation suspension member likely causes engineering extension to complete; And need with locating part suspension member is on center shaft spacing when suspension member is fixed, because locating part and central shaft are metal, easily cause between locating part and central shaft and occur corrosion, cause unnecessary loss.
Summary of the invention
For solving the problem that in-site installation suspension member is wasted time and energy, and etching problem between the locating part of fixing suspension member and central shaft, the present invention devises a kind of suspension member that can be used for managing interior inserted component Fast Installation, this suspension member can when factory-assembled and heat exchanger tube plug-in part fit together.In in-site installation heat exchanger tube during inserted component, suspension member can with interior inserted component by heat exchanger tube, is combined into a complete work suspension member, saves the field erected time at mouth of pipe suspension member by left and right two parts.The screw clamping device at suspension member top can make suspension member fixing on center shaft, prevents the corrosion between locating part and central shaft.
