Abstract

An automatic descaling, antiscaling and cleaning device for heat transfer tubes is suitable for various shell-and-tube heat transfer devices, such as heat exchangers, condensers, evaporators and the like. The plastic twisted hole belt type heat exchanger is composed of a plastic twisted hole belt (2) which freely rotates in a heat transfer pipe (1), wherein an axial fixing frame (4) is arranged at the liquid inlet end of the heat transfer pipe (1), a pin shaft (7) is arranged on the axial fixing frame, and the twisted hole belt (2) is connected to the pin shaft, so that the twisted hole belt (2) is axially positioned in the heat transfer pipe. When the device is operated, the tube side liquid drives the twisted hole belt (2) to rotate, thereby achieving the purposes of heat transfer enhancement and online automatic descaling and scale prevention. The twisted belt (2) is made of engineering plastics, does not wear the inner wall of the pipe, and can be applied to both vertical and horizontal heat transfer equipment.

Description

Flushing device for descaling and scale prevention of heat transfer tube
The cleaning device of descaling and antiscaling is applicable to various shell-tube type heat-transfer equipments, as heat exchanger, condenser, evaporimeter etc. in a kind of heat-transfer pipe.
The heat-transfer pipe interpolation is gone into the existing more reported in literature of heat conduction reinforced device that static distortion band constitutes, and strengthening effect is generally more than 30%.As everyone knows, static distortion band does not clean the function of antiscale, but considerable shell and tube exchanger is arranged, and contamination is long dirty easily in the production run process, causes heat transfer efficiency significantly to descend, and resistance rises, even the part heat-transfer pipe blocks.
The utility model aims to provide in a kind of heat-transfer pipe that is applicable to the shell-tube type heat-transfer equipment, can clean antiscale automatically, can realize the cleaning device of automatic desludging antiscale in the heat-transfer pipe of heat conduction reinforced a kind of like this dual-use function again simultaneously.
Fig. 1 is the structural representation of the cleaning device of automatic desludging antiscale in the heat-transfer pipe.
Fig. 2 is the apparatus structure schematic diagram of the distortion band of multiple perforate mode.
The utility model is achieved through the following technical solutions:
Insert the distortion band [ 2 ] isometric substantially in the heat-transfer pipe [ 1 ] with heat-transfer pipe [ 1 ].Offer many holes [ 3 ] above the distortion band [ 2 ].The radial dimension of distortion band [ 2 ] is less than the internal diameter of heat-transfer pipe [ 1 ].The inlet end of heat-transfer pipe [ 1 ] is equipped with axial restraint frame [ 4 ], there are one or more flow-in holes [ 5 ] at the middle part of axial restraint frame [ 4 ], so that make in the smooth and easy inflow heat-transfer pipe of tube side liquid [ 1 ], the gross area of flow-in hole [ 5 ] is equal to or greater than the interior sectional area of heat-transfer pipe [ 1 ].The head of axial restraint frame [ 4 ] has an axis hole [ 6 ] with the concentricity line of heat-transfer pipe [ 1 ], and a bearing pin [ 7 ] is housed in the axis hole [ 6 ].The diameter of bearing pin [ 7 ] is littler than the aperture of axis hole [ 6 ], and the radial dimension of bearing pin [ 7 ] head is greater than axis hole [ 6 ], and bearing pin can freely rotate in axis hole [ 6 ] like this, but axial location is fixed.The afterbody of bearing pin [ 7 ] is connected with distortion band [ 2 ].During operation, tube side fluid flows in the heat-transfer pipe [ 1 ] by the flow-in hole [ 5 ] at axial restraint frame [ 4 ] middle part, and distortion band [ 2 ] is just scraped the inside pipe wall surface by the liquid in pipe driven rotary, realizes the antiscaling, descaling effect; Because of the guide functions of porous distortion band [ 2 ] itself, form the basic complexity that flows to helical flow and flow again, add that distortion band [ 2 ] rotation scrapes the direct perturbation action to the border detention layer, and realize heat conduction reinforced simultaneously.
Distortion band [ 2 ] adopts the engineering plastics manufacturing, can reduce cost, and avoids the wearing and tearing of heat-transfer pipe inwall effectively, and good Corrosion Protection is arranged again simultaneously.
The utility model has the advantages that, have automatic on-line cleaning antiscale and heat conduction reinforced dual-use function in the heat-transfer pipe pipe, fluid resistance is little, Fouling Cleaning is relatively evenly clean, the heat-transfer pipe inwall does not does not wear and tear, vertical heat-transfer equipment and horizontal heat-transfer equipment can be used, also all can be general to new control equipment and existing equipment technological transformation.
Embodiment 1, as shown in Figure 1, dress distortion band [ 2 ] in the heat-transfer pipe [ 1 ], distortion band [ 2 ] is made by engineering plastics.Be arranged in the hole of offering on the distortion band [ 2 ] [ 3 ] on the edge of the nearly both sides of distortion band [ 2 ], perhaps be arranged on the center line of distortion band [ 2 ], also can on center line and edge, all offer hole [ 3 ].The hole shape in these holes [ 3 ] is generally circle, also can be other shape, as ellipse.These holes [ 3 ] help augmentation of heat transfer, help reducing flow resistance again.But, perforate is more conducive to reduce fluid resistance on the center line, and the edge perforate more helps heat conduction reinforced.The mode of perforate can be with [ 2 ] position of opening material all dig out distortion and form the hole; Also can be that periphery is tripartite cuts, and the part that makes incision forms the hole of hole sideband wing along the side bending of not cutting.Axial restraint frame [ 4 ] is made by engineering plastics, and the head of bearing pin [ 7 ] is the pin of band cap shape, and afterbody is connected with distortion band [ 2 ].
Embodiment 2, and as shown in Figure 2, axial restraint frame [ 4 ] is made by engineering plastics.Bearing pin [ 7 ] is the metal wire structure of wear-and corrosion-resistant, directly is bent to form its gib head by wire, and the afterbody of bearing pin [ 7 ] hooks distortion band [ 2 ].Distortion band [ 2 ] material is engineering plastics.Distortion band [ 2 ] can be a whole piece, also can be that two sections or multistage are formed by connecting; The direction of twist of each section can be opposite, also can be identical; Or the inconsistent plurality of sections distortion of perforate mode is with [ 2 ] to be formed by connecting.The multistage connection can make things convenient for long transportation and manufacturing processing of twisting band [ 2 ], also can utilize the connection of the distortion band of different direction of twists to regulate the velocity of rotation that distortion is with according to the actual motion needs simultaneously.
