Abstract
The utility model relates to an on-line anti-scaling and intensified heat exchange device of a tube type heat exchanger, and adopts the scheme that fixed brackets installed at two ends of a stainless steel rope under tensioning state are respectively fixed at two ends of a heat exchange pipe; stop collars are fixed on the stainless steel rope at equal intervals; and corotation impellers and counterotation impellers are sequentially installed on the stainless steel rope positioned at the front end part of each stop collar. The utility model has the advantages of simple structure, reasonable design, improved decontamination and heat transfer effects and long service life, and weeds and other flocculus can not be left on the waterward sides of the impellers due to chamfer angles arranged thereon, so that the impellers can continuously steadily operate in dirty tube side fluid heat transferring medium.
Description
Technical field
The utility model relates to a kind of tube type heat exchanger on-line antiscale and reinforced heat exchanger.
Background technology
Its heat exchanger tube inwall fouling inevitably after the tubular heat exchanger operation, and then cause heat exchange efficiency to reduce, be example with the turbine condenser, move after 1 year, heat exchange efficiency reduces 20-30%.Machinery when tubular heat exchanger heat exchanger tube inwall cleans based on overhaul at present cleans or Chemical cleaning, and online in good time cleaning seldom.At the in good time cleaning method of conventional online, middle segmented twisted strip is a kind of advanced person's a method.
Summary of the invention
The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, and a kind of compact conformation, reasonable in design is provided, the tube type heat exchanger on-line antiscale of online in good time cleaning and reinforced heat exchanger.
In order to achieve the above object, the technical solution adopted in the utility model is: the stainless steel rope ends that is tension is equipped with fixed mount and is separately fixed at the heat exchanger tube two ends, stainless steel rope equal intervals is fixed with stop collar, is positioned at first impeller, second impeller that positive and negative rotation direction is installed on the stainless steel rope at each stop collar front end position successively in order.
The utility model has the advantages that:
1, impeller independent operating separately damages the operation that can not influence other impeller as certain impeller.
2, owing to meeting breakdown speed of the wake flow mixed zone between the impeller and boundary layer, its strengthening effect is better than continuous twisted strip.
3, rotation direction is opposite, and specific rotation can obtain bigger moment of torsion and rotating speed to unanimity.
4, rotation direction is opposite, and specific rotation can obtain littler spacing to unanimity, to arrange more impeller, improves scrubbing and heat-transfer effect.
5, rotation direction is opposite, makes wheel speed unanimity in the whole heat exchanger tube, avoids the consistent low phenomenon in preceding high back that produces of rotation direction.
6, rotation direction is opposite, impeller moment of torsion direction vector is opposite, guarantee that impeller moves at the heat exchanger tube center substantially in the whole heat exchanger tube, the scraped finish of heat exchanging inside pipe wall is slight, but so promptly guaranteed also enhanced heat exchange of antiscale, do not exchange heat pipe again and cause bigger wearing and tearing, self wear extent also reduces, thereby has improved service life.
7, rotation direction is opposite, and impeller moment of torsion direction vector is opposite, makes impeller action total moment of torsion and be zero to the stainless steel cable, and then has alleviated the stressed of fixed mount.
8, the impeller side that meets water is provided with chamfering, does not hang floccules such as staying weeds, and its effect is the winding that has prevented weeds and floccule in the water, guarantees impeller operation continually and steadily in dirty tube side fluid heat transferring medium.

The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
By Fig. 1-Figure 16 as can be known, stainless steel rope 1 two ends that the utility model is tension are equipped with fixed mount 3 and are separately fixed at heat exchanger tube 6 two ends, stainless steel rope 1 equal intervals is fixed with stop collar 2, is positioned at first impeller 4, second impeller 5 that positive and negative rotation direction is installed on the stainless steel rope 1 at each stop collar 2 front end position successively in order.
Described first impeller 4, second impeller 5 are single leaf, double leaf or three leaves.
Described first impeller 4, second impeller 5 are hollow or real core.
The side that meets water of described first impeller 4, second impeller 5 is provided with chamfering.
Described fixed mount 3 front end positions are provided with filter mantle 7.
The utility model according to the length of heat exchanger tube 6, is through a plurality of first impellers 4, second impeller 5 on the stainless steel rope 1 when installing in heat exchanger, separates the location by stop collar 2, and two ends are fixed on heat exchanger tube 6 two ends by fixed mount 3, and are tension.When in the fluid flowing pipe, drive its rotation by the blade on first impeller 4, second impeller 5, thereby play the effect that tube wall prevents fouling of sweeping of scraping.The fluid of disturbance simultaneously, enhanced heat exchange.First impeller 4, second impeller 5 select hollow impellers, single leaf and bilobed wheel to reduce the rotary resistance of impeller and the flow resistance of fluid according to actual conditions such as on-the-spot water quality, current.Fixed mount 3 front end positions are equipped with filter mantle 7, and filter mantle 7 is provided with ring-shaped groove, can filter out cotton-shaped foreign material in the water, are fit to the unclean occasion of water quality.
When the utility model tube side fluid heat transferring medium (being generally water) is flowed through in the heat exchanger tube, drive first impeller 4,5 rotations of second impeller, first impeller 4, disturbance boundary layer, second impeller, 5 edge, and fast slight scraped finish heat exchanger tube inwall, and then realize antiscale and enhanced heat exchange function.
