Problems solved by technology
The rubber balls currently used have a porous and soft soft structure. It is difficult to control the wet diameter and specific gravity of the rubber balls during use, and they are also easy to be attached by sludge, dirt, and microorganisms, so the circulation performance is not good. Recycling is the rubber ball. If it is hindered, the recovery efficiency is low; when the rubber ball is made into a solid shape, the resistance to the fluid is relatively large, and it is easy to block the pipeline

The invention discloses a rubber ball with a hollow structure and random motions for a heat exchange tube, which mainly comprises a connecting ring, a hollow and gaps, wherein the hollow is a hollow structure in the connecting ring, the gaps are hollow parts in the connecting ring, the left sides, the right sides, the upper sides and the lower sides of the gaps on the same plane are all asymmetric, the outer surface of the connecting ring is circular or approximately circular, and the diameter of the connecting ring is equal to or smaller than the inner diameter of the heat exchange tube. In the technical scheme, the gaps on the connecting ring further increase the hollow parts, the asymmetric gaps cause fluid to act on the connecting ring to form unbalanced rotary moment, the rubber ballcarries out uninterrupted random rotary motions, the outer surface of the connecting ring can wash the inner wall of the heat exchange tube effectively, the rubber ball moves randomly and also can not be blocked in the heat exchange tube, the flexibility of the motions of the rubber ball is enhanced, the turbulivity of the fluid when passing through the gaps is increased, and the rubber ball has the effect of reinforcing heat transfer; and the hollow structure decreases the weight of the rubber ball, increases the motion flexibility of the rubber ball in the heat exchange tube and saves the material cost.
Description
technical field [0001] The invention relates to a component of a water purification device, in particular to a component used for cleaning and enhancing heat transfer in heat exchange tubes in shell-and-tube heat exchangers, heat exchange reactors and other equipment. Background technique [0002] The rate of energy consumption in today's world continues to increase, but some energy sources on the earth are limited, such as oil and natural gas. It has always been easy to deposit dirt in the heat exchange tubes, especially when the cooling water is a fluid containing impurities, such as sea water and river water, the heat exchange tubes will deposit very thick dirt in a short period of time, such as 3-5 days. The deposited dirt is very harmful. The thermal resistance of the dirt is very large, which directly and greatly reduces the heat transfer efficiency in the heat exchange tube, resulting in a great waste of energy. In addition, the dirt is corrosive and will shorten the ...
