Description

Open type suspension member and sleeve pipe stopping means in the heat exchanger tube
Technical field
The present invention relates to a kind of support component and sleeve pipe stopping means that is applied to the interior inserted component of augmentation of heat transfer and antifouling scrubbing in the heat exchanger tube in the equipment such as shell-and-tube heat exchanger, heat exchange reactor.
Background technology
21st century is along with the continuous progress of society, current social energy-saving and emission-reduction are the key technologies that the whole world is all paid much attention to, especially all to be applied to many heat exchangers in various fields such as oil, chemical industry, thermoelectricity, nuclear power, metallurgy, light industry, aviation device and boats and ships vehicles, what wherein be most widely used is shell-and-tube heat exchanger, but inwall ubiquity lamination dirt in these heat exchanger tubes, cause fluid transporting resistance in pipeline to increase, meeting blocking pipe when serious, heat transfer property greatly descends simultaneously; Dirt can seriously reduce heat transfer efficiency and cause great energy waste in the heat exchanger tube, and meanwhile dirt generally has corrosivity, therefore corrosion of tube wall, and leak fluid causes major safety risks.
On the problems referred to above, treating method traditionally is forced to exactly take stop production and please professional cleaning personnel be cleaned, and has so not only stopped over the manufacturing schedule of factory, also needs to pay expensive cleaning charge simultaneously and uses; In order to address this problem better, people study the on-line automatic augmentation of heat transfer that employing do not stop production and the various ways and the device of descaling and antiscaling always.China Patent No. is ZL200520127121.9 afterwards, the patent application of denomination of invention for " rotator type cleaning and heat-transfer enhancing device " disclosed, this device is to be made of fixed mount, rotor, flexible shaft and stay pipe, and two fixed mounts are separately fixed at the two ends of heat exchanger tube; The appearance of rotor has scroll, and centre bore is arranged on the rotor; Stay pipe is located between rotor and the fixed mount, and flexible shaft passes the centre of rotor hole and stay pipe is fixed on two fixed mounts.This device has the function of on-line automatic antiscaling, descaling and augmentation of heat transfer, under the situation of fluid following current or adverse current in heat-transfer pipe, the effect of antiscaling, descaling and augmentation of heat transfer is arranged all.But shortcoming be certain fluid by the time, the rotary speed of rotor is that the lead angle by the spiral shell rib is determined that lead angle is more little, promptly is fast more in the rotary speed of spiral shell rib helical pitch hour rotor, the resistance of convection cell increases thereupon simultaneously; Be head it off, Chinese patent application numbers 200620172805.5, denomination of invention is " low flow resistance rotor of cleaning and heat-transfer enhancing in the heat-transfer pipe ", this device is by rotor, suspension member and is connected axis and constitutes that suspension member is to be fixed on the heat-transfer pipe two ends, and the two ends that connect axis are separately fixed on the suspension member, a plurality of rotors are installed on and connect on the axis, rotor is to be made of hollow shaft and blade, and it is same skewed that each blade becomes with hollow shaft, and adjacent blades is end to end.This novel energy-saving and emission-reduction product through industrial inspection and application, has all reached augmentation of heat transfer and tartar preventing iron tartar effect preferably.Heat exchanger tube arranging in heat exchanger is that certain distance is arranged, and the space between the heat exchange pipe external surface is the shell fluid space.The suspension member that is installed in the heat exchanger tube end can reduce the flow that fluid flows into, next is a heat exchanger tube owing in installation and use deformation can take place, become ellipse or other shapes by circle, cause can comparing when suspension member is installed difficultly and wasting time, installation effectiveness is lower.
