Description

The rotator type cleaning and heat-transfer enhancing device
Technical field
The utility model relates to the antiscaling, descaling in the heat-transfer pipe that is used for pipe type heat transfer equipment and the device of augmentation of heat transfer, particularly utilizes the be used as power device of automatic antiscaling, descaling and augmentation of heat transfer of heat-transfer pipe inner fluid.
Background technology
Heat exchanger is after contamination, fouling on the heat-transfer area, can make poor heat transfer, fouling seriously can cause the fluid transporting resistance to increase even cause line clogging, and fouling not only can cause underdeposit corrosion, potential safety hazard, increase energy resource consumption and production cost, and stopping production to clean also can influence production.
In numerous antiscaling, descaling methods, the spiral band method is a kind of method of utilizing the fluid dynamic energy online automatic desludging.A kind of device of descaling and antiscaling is disclosed in " cleaning device of descaling and antiscaling in the heat-transfer pipe " (ZL 95236063.2), this device is made of the mutually isometric substantially distortion band of installing in the heat-transfer pipe and heat-transfer pipe, the radial dimension of distortion band is less than the internal diameter of heat-transfer pipe, there is flow-in hole at the middle part that the axial restraint frame is housed at heat-transfer pipe inlet end, the head of axial restraint frame has an axis hole, dress bearing pin in the axis hole, the afterbody of bearing pin is connected with the distortion band." spiral enhanced heat exchange of dual turbulent and automatic descaling apparatus " (publication number CN 1424554) discloses a kind of enhanced heat exchange and automatic descaling apparatus, this device is except being provided with spiral band, fixed mount, spiral band is arranged in the helix tube, drives spiral band by flowing by the fluid in the helix tube and rotates.Though shape is mobile in the shape of a spiral in helix tube for medium, helps improving the heat exchange effect, the slit between spiral band rotation and the helix tube inwall is inhomogeneous, and spiral band is little and inhomogeneous to the scraping effect of helix tube inwall dirt layer, is unfavorable for scale removal.More than the distortion band (or claim spiral band) of apparatus for eliminating sludge of two kinds of spiral band methods all be that an end is connected with fixed mount in heat-transfer pipe, the other end is unfixed, though the radial dimension of distortion band, also causes the outer rim of the distortion band heat-transfer pipe inner surface of directly swiping easily less than the internal diameter of heat-transfer pipe.And fluid can only flow to the effect that scale inhibition and augmentation of heat transfer are just arranged in the pipe from a direction.
Summary of the invention
The utility model provides a kind of rotator type cleaning and heat-transfer enhancing device that is used in the pipe type heat transfer equipment heat-transfer pipe.It has the function of the pre-good antiscale property of automatic on-line, cleaning and augmentation of heat transfer, under the situation of fluid following current or adverse current in heat-transfer pipe, the effect of scale inhibition and augmentation of heat transfer is arranged all.
The utility model rotator type cleaning and heat-transfer enhancing device, this device is made of fixed mount, rotor, steel wire and stay pipe.Fixed mount is 2, and two fixed mounts are separately fixed at the two ends of heat-transfer pipe; The appearance of rotor has the spiral shell rib, and centre bore is arranged on the rotor; Stay pipe is located between rotor and the fixed mount, and steel wire passes the centre of rotor hole and stay pipe is fixed on two fixed mounts.
The utility model device, the spiral shell rib head number of rotor is single head or bull.On the edge of rotor spiral shell rib perforate can be arranged.
The utility model device, rotor constitutes for one or more series connection, and the total length of rotor is less than heat-transfer pipe.
The utility model device, fixed mount is connected with the heat-transfer pipe socket joint.
The utility model device, the sidewall of fixed mount or flow-in hole is axially arranged, there is an axis hole termination of fixed mount, and steel wire passes the axis hole knot on fixed mount.
The utility model rotator type cleaning and heat-transfer enhancing device, this device are placed in the heat exchanger and use.Place one or more rotors in Exchanger Tubes, the total length of rotor is slightly less than heat-transfer pipe length.The external diameter of rotor is less than the internal diameter of heat-transfer pipe, and the centre of rotor bore dia is slightly larger than the external diameter of steel wire, and steel wire is fixed on the axial restraint frame at heat-transfer pipe two ends with tension, makes the central lines of the center line and the heat-transfer pipe of steel wire.Rotor can rotate under the effect of fluid media (medium) freely.The sidewall of fixed mount or two or more flow-in holes are axially arranged, so that the medium of heat exchanger tube side flows in the heat-transfer pipe smoothly, the gross area of flow-in hole equates with the interior area of section of heat-transfer pipe substantially.During operation, the tube side medium flows in the heat-transfer pipe by the flow-in hole on the fixed mount, and rotor rotates under the impetus of fluid, realizes the antiscaling, descaling effect.The structure of rotor spiral shell rib has guide functions, and the complexity that makes fluid advance in the shape of a spiral flows.On rotor spiral shell rib, establish perforate, can reduce the resistance of fluid, the augmentation of heat transfer effect.Under the impetus of fluid, the rotor fast rotational, strengthening fluid is disturbance in heat-transfer pipe, reduces heat transfer boundary layer, plays the augmentation of heat transfer effect.
Rotor adopts plastic production, and fixed mount adopts plastics or stainless steel material to make.Under the situation of steel wire tension, the rotor heat-transfer pipe that can not wear and tear, safety coefficient height; And it is low, corrosion-resistant to have cost.Rotor can be applicable to the heat-transfer pipe of different length during by a plurality of the composition.The utility model is made, assembling, use, change convenient, under the situation of fluid following current or adverse current in heat-transfer pipe, the effect of scale inhibition and augmentation of heat transfer is arranged all.
The utility model rotator type cleaning and heat-transfer enhancing device is applicable to pipe type heat transfer equipment, comprises the occasion of fouling in horizontal heat exchanger and vertical heat exchanger, condenser and the needs cleaning straight tube.Have the dual-use function of interior automatic on-line cleaning antiscale of heat-transfer pipe pipe and augmentation of heat transfer, can easily be used for the technological transformation of existing heat-transfer equipment.
