Description
Technical Field
[0001] The utility model relates to the technical field of heat exchangers, in particular to a heat exchanger that is convenient to use. Background Art
[0002] Heat exchangers are devices that transfer part of the heat of hot fluid to cold fluid. They are also called heat exchangers. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc. They are widely used. However, the most troublesome thing about the use of heat exchangers is the generation of scale. Since calcium and magnesium ions in water and carbonate ions in water form calcium carbonate and magnesium carbonate, which are difficult to dissolve in water, they aggregate and precipitate to form scale. Over time, they will corrode the internal metal, reduce the efficiency of heat exchange, affect the life of the equipment, and are very likely to cause pipe bursts and safety accidents.
[0003] China Public Invention: CN202320897725.X discloses a heat exchanger that is easy to install and is used in the field of heat exchangers. The utility model has flanges 1 fixedly bolted at both ends of the heat exchanger body, and a fixing rod is provided at the bottom of the heat exchanger body. A guide rod is provided inside the fixing rod that penetrates one end of the fixing rod. When the heat exchanger that is easy to install is used, the heat exchanger body is disassembled and repaired by disassembling flange 1. During installation, the guide rod is first pulled out from the inside of the fixing rod, and then the clamping block at the bottom of flange 1 is clamped with the clamping block, and then the guide rod is pushed to move inside the fixing rod. The guide rod plays a role in stabilizing and smoothing the movement of flange 1, and is convenient for sliding and positioning it. After continuing to move forward, the rod is inserted into the slot to increase its positioning. The cooperation of the fixing rod and the guide rod increases the convenience of installing the heat exchanger body and increases its positioning and guiding performance of installation.
[0004] The heat exchanger softens water and reduces scale through the descaling filter element, but the descaling effect is poor after saturation, and frequent replacement of filter materials leads to low utilization, high cost, and inconvenience in use;
[0005] To this end, a heat exchanger that is convenient to use is proposed. Utility Model Content
