The inside of the rubber ball of the invention is a hollow structure, the axial direction of the hollow shaft is arc-shaped or conical, and the rubber ball expands when a fluid acts on the inner surface, thereby the contact area of the outer surface of the rubber ball and the inner wall of the heat exchange tube is increased, and the forward driving force of the fluid for the rubber ball is increased; the mass of the rubber ball is reduced due to the hollow structure, the material cost is saved, the resistance for the fluid is reduced, and the circulation performance of the rubber ball in the heat exchange tube is improved; the vane is arranged in the hollow shaft, and when the fluid flows through the vane, the rubber ball receives an upward circumferential force vertical to the diameter to rotate, thereby the cleaning effect is enhanced; and the rubber ball ceaselessly rotates, thereby the dirt on a ball collecting net can be cleaned, and the recovery rate of the rubber ball is increased.
Description
Technical field
The present invention relates to a kind of element of water purification installation, particularly a kind ofly be applied in the equipment such as shell-and-tube heat exchanger, heat exchange reactor cleaning element in the heat exchanger tube.
Background technology
Deposition dirt easily in the heat exchanger tube is when containing the fluid of impurity at cooling water particularly all the time, and for example when seawater, river, heat exchanger tube will deposit very thick dirt in very short time as 3-5 days.The dirt of deposition has very big harmfulness, and the thermal resistance of dirt is very big, has directly lowered the heat transfer efficiency in the heat exchanger tube greatly, and dirt is also had corrosivity in addition, can shorten the life-span of heat exchanger tube, thereby bring very big economic loss to factory.The method of dirt has machine cleaning technique, glueballs cleaning technique and on-line cleaning technology in the heat exchanger tube for removing.The very big hydraulic pressure of machine pressure wash Technology Need, very high to the requirement of machine, but the result of machine pressure wash is not satisfactory, it is complete inadequately to clean dirt.The on-line cleaning technology is the technology that last decade grows up, generally be that interspersed descaling component cleans automatically in heat exchanger tube, consequently the cleaning to dirt produces effect, but can pose a big pressure loss, influence runner, entrainment in the fluid is easy to stop up heat exchanger tube simultaneously, and this technology is perfect not enough simultaneously.Technology is to utilize the glueballs on-line cleaning relatively preferably, and shape and material can be adjusted, and has friction effect still can not damage tube wall to tube wall, and glueballs can reuse simultaneously, and cost is lower.The patent No. 200710098489.0, name is called a kind of member for online cleaning and removing scale of heat exchange tube, and this element has runner, but the shortcoming of element is a maximum outside diameter to be contacted with the heat exchanger tube inwall is that line contacts, the effect of cleaning dirt is limited, and hollow shaft is a d-axis, and the element traffic capacity forward is limited; The glueballs that uses at present is the soft body structure of porous softness, and in use the hygrometric state diameter of glueballs and proportion are difficult to control, and also is easy to by mud, dirt and microorganism etc. accompanyingly, so trafficability performance is bad, glueballs is hindered during recovery, and organic efficiency is lower; When glueballs was made solid shape, the resistance of convection cell was bigger, easily blocks pipeline.
