Description

Technical Field

[0002] Heat exchangers are common heat transfer equipment in industrial processes. Their main function is to transfer heat from hot fluids to cold fluids to meet the temperature requirements of the process. However, during use, impurities in the heat exchange medium often cause scaling problems inside the heat exchanger, affecting its normal operation. The main problem with current heat exchangers is that it is difficult to effectively filter the heat exchange medium during use, resulting in the accumulation of impurities on the inner wall of the heat exchanger and the surface of the heat exchange components, which in turn affects the service life of the equipment.

[0022] Preferably, it also includes a stirring component, which includes a stirring motor 206, a stirring shaft 207, a sealed shaft seat 208, a movable seat 209 and a stirring blade 210. The stirring motor 206 is arranged on the top of the pretreatment box 102, and the output end of the stirring motor 206 is connected to the stirring shaft 207. The stirring shaft 207 is arranged inside the pretreatment box 102 and passes through the sealed partition 103 and is rotatably arranged on the movable seat 209. The movable seat 209 is arranged on the bottom surface of the pretreatment box 102. The stirring blade 210 is arranged on the side of the stirring shaft 207, and the sealed shaft seat 208 is arranged at the connection between the stirring shaft 207 and the sealed partition 103, and the stirring shaft 207 is movably connected to the sealed shaft seat 208. When in use, the stirring motor 206 drives the stirring shaft 207 to rotate, and the stirring shaft 207 drives the stirring blade 210 to rotate, stirring the filtered heat exchange medium, so that it fully reacts with the water softening material inside the pretreatment box 102, and the water softening material adsorbs the calcium ions and magnesium ions in the heat exchange medium to soften the heat exchange medium.

Therefore, the setting of the stirring component further softens the heat exchange medium, improves the water quality, and reduces the risk of scaling.

[0023] Preferably, two sealing door panels 205 that can be opened and closed are provided on one side of the pretreatment box 102 away from the heat exchanger body 101, one of the sealing door panels 205 is correspondingly arranged at the top position of the sealing partition 103 and the bottom of the sealing door panel 205 is connected to the sealing partition 103, and the other sealing door panel 205 is arranged at the bottom position of the side panel of the pretreatment box 102.

[0027] Preferably, a removable sealing plate is provided on the side of the pretreatment box 102. The design of the removable sealing plate makes the maintenance process more flexible, which not only facilitates the cleaning and replacement of the water softening material, but also provides a more flexible operating space for the inspection and maintenance of other components inside the pretreatment box 102. It should also be noted that the water softening material can be selected as a softening resin. It should be noted that the softening resin is usually composed of polymer particles and has a negative charge. These particles have sodium ions on their surface. The softening process is mainly achieved through ion exchange, and the specific steps are as follows:

[0028] Adsorption of hardness ions: Water containing hardness ions is passed through a softening resin column. Hardness ions (mainly Ca2+ and Mg2+) are adsorbed by the resin and replaced with sodium ions on the resin surface. Na+ on the resin is released into the water.

[0029] Ion exchange: Ion exchange is a key process in softening water. Hardness ions (Ca2+ and Mg2+) are exchanged with sodium ions on the resin surface. Because Na+ ions on the resin are easier to release than Ca2+ and Mg2+ ions, they are more easily stripped from the resin surface.

[0030] Resin regeneration: Over time, the sodium ions on the softening resin are gradually replaced by hardness ions, causing the resin to fail. In order to maintain the softening effect of the resin, the resin needs to be regenerated or regenerated, usually by passing a brine solution (NaCl) through the resin column to recharge the sodium ions onto the resin.

[0031] It should be noted that the staff transports the brine through the connecting pipe provided at the front end of the pretreatment box 102. The brine reacts with the softened resin to restore the failed resin to the sodium type resin for re-softening. Therefore, the softened resin can be used for a long time.

[0032] The anti-scaling high-efficiency heat exchanger provided by the utility model comprises a heat exchanger body 101 and a pretreatment box 102 connected to the heat exchanger body 101. Through the filter plate 104 arranged in the pretreatment box 102, the heat exchanger realizes efficient filtration of impurities in the heat exchange medium, effectively reduces the accumulation of impurities on the inner wall of the heat exchanger and the surface of the components, thereby significantly slowing down the formation process of scaling. At the same time, the cleaning brush 107 is driven to rotate by the driving motor 105, especially in the cleaning process on the water inlet side of the filter plate 104, the impurities are thoroughly cleaned by the cleaning brush 107, avoiding the accumulation of impurities and the blockage of the filter plate 104, which not only ensures the efficient filtration of the heat exchange medium, but also effectively reduces the risk of scaling. Therefore, the anti-scaling high-efficiency heat exchanger greatly extends the service life of the heat exchanger, and by preventing the formation of scaling, it not only reduces the maintenance cost, reduces the frequency of equipment maintenance and replacement, but also improves the stability and performance of the equipment.

[0033] The above disclosures are only several preferred embodiments of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
