Problems solved by technology

[0002] After the tube-and-tube heat exchanger is in operation, the inner wall of the heat exchange tube will inevitably foul, which will lead to a decrease in heat exchange efficiency. Taking the steam turbine condenser as an example, after one year of operation, the heat exchange efficiency will decrease by 20-30%.
At present, the cleaning of the inner wall of the heat exchange tube of the tube-and-tube heat exchanger is mainly performed by mechanical cleaning or chemical cleaning during overhaul, and online timely cleaning is rare.

Abstract

The invention relates to a tube type heat exchanger on-line antiscale and reinforcing heat exchange device. Fixed mounts arranged on both ends of a strained stainless steel rope are respectively fixed on both ends of a heat exchange tube; the stainless steel rope is fixed with limit sleeves at equal intervals; and the stainless steel rope at the front end of each limit sleeve is orderly provided with a forward-rotation impeller and a reverse-rotation impeller. The invention has the advantages of simple structure, reasonable design and long service life, enhances the effects of decontamination and heat transfer; and the upstream side of the impeller is provided with a chamfer so as not to hang and retain weed and other floccules, thereby ensuring continuous stable operation of the impellers in smudgy tube side fluid heat exchange media.

Description

technical field [0001] The invention relates to an on-line anti-scaling and enhanced heat exchange device for a tube-and-tube heat exchanger. Background technique [0002] After the shell and tube heat exchanger is in operation, the inner wall of the heat exchange tube will inevitably foul, which will lead to a decrease in heat exchange efficiency. Taking the steam turbine condenser as an example, after one year of operation, the heat exchange efficiency will decrease by 20-30%. At present, the cleaning of the inner wall of the heat exchange tube of the tube-and-tube heat exchanger is mainly performed by mechanical cleaning or chemical cleaning during overhaul, and online timely cleaning is rarely performed. Among the existing on-line timely cleaning methods, the segmented spiral twisted belt is an advanced method. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the above-mentioned technologies, and provide an on...
