Embodiment 1

[0077] Such as Figure 1 ~ Figure 4 As shown, this embodiment provides a heat exchanger for accelerating heat exchange, and the heat exchanger for accelerating heat exchange at least includes:

[0078] Shell 1 , head 2 , base 7 , heat exchange tube 8 , separator 12 , electrode 13 , stirring paddle 14 and connecting shaft 15 .

[0079] Such as figure 1 As shown, the housing 1 is a barrel-shaped structure. In this embodiment, the housing 1 is a cylindrical structure, and the diameter of the housing 1 is D1. The housing 1 is arranged laterally on the base 7, the upper surface of the base 7 is an arc-shaped structure, which fits with the arc-shaped surface of the housing 1, and the lower surface of the base 7 is a plane , used to support the housing 1 to keep the housing 1 stable.

[0080] Such as Figure 1 ~ Figure 2 As shown, the two ends of the housing 1 are connected to the head 2, and the housing 1 is separated from at least one head 2 by a partition 12. In this embodimen...

Embodiment 2

[0089] This embodiment provides a heat exchanger for accelerating heat exchange. The structure of the heat exchanger for accelerating heat exchange is similar to that of Embodiment 1. The difference is that the liquid stirring device in this embodiment is a magnet, which is driven by stirring. The device is a magnetic stirring device.

[0090] Specifically, such as Figure 5 As shown, the stirring driving device includes a magnet 17 and a filter screen cover 16, and the stirring driving device is a magnetic stirring device 18. The filter screen cover 16 is fixed on the partition between the housing 1 and the head 2, and the magnet 17 is arranged in the filter screen cover 16 to limit the magnet 17 Between the filter screen cover 16 and the partition plate 12, the magnet 17 is prevented from rotating and hitting the heat exchange tube 8, which plays a protective role. The magnetic stirring device 18 controls the rotation of the magnet 17 through magnetic force, so as to stir ...

Embodiment 3

[0092] This embodiment provides a heat exchanger for accelerating heat exchange. The structure of the heat exchanger for accelerating heat exchange is similar to that of Embodiment 1. The difference is that the size of the heat exchange tubes in this embodiment is the same as that of Embodiment 1. The heat exchange tubes in the tubes are of different sizes.

[0093] Specifically, the inner wall of the heat exchange tube 8 is provided with a screw thread 10, the pitch L of the screw thread 10 is 30 mm, and the groove depth H is 0.9 mm. The ratio of the helical diameter D2 of 8 was set to 0.18. The heat exchanger for accelerating heat exchange in this embodiment can also achieve the purpose of anti-fouling.

Abstract

The invention provides a heat exchanger for accelerating heat exchange and a heat exchange method. The heat exchanger comprises a shell, end sockets, a liquid stirring device, a heat exchange pipe, stirring driving devices, the liquid stirring device and the heat exchange pipe are arranged in the shell, and the stirring driving devices are arranged in the end sockets. A heat exchange medium entersthe shell through a heat exchange medium feeding port, and flows out of the shell through a heat exchange medium discharging port. Materials enter the heat exchange pipe in the shell through a material feeding port and flow out of the heat exchange pipe through a material discharging port. The heat exchange medium is stirred, so that the heat exchange medium is in full contact with the heat exchange pipe, and the materials and the heat exchange medium achieve energy interchange through the pipe wall of the heat exchange pipe. According to the heat exchanger, the heat exchange medium is promoted to accelerate motion through the stirring device, and the heat exchange efficiency is improved. The thread screw heat exchange pipe is adopted, the scouring force of the materials on the pipe wallis greatly increased, and condensation and scale formation of the pipe wall are avoided; scale formation prevention and energy saving are balanced by optimizing the size of the heat exchange pipe; theheat exchange pipe is made from aluminum-based alloy containing nano-graphite, the heat transferring performance is high, corrosion resistance is achieved, the application range is wide, the specificgravity is small, and the weight is low.

Description

technical field [0001] The invention relates to the field of heat exchangers for accelerating heat exchange, in particular to a heat exchanger for accelerating heat exchange and a heat exchange method. Background technique [0002] A heat exchanger is a device that transfers part of the heat of the heating medium to the refrigerant, also known as a heat exchanger. Heat exchangers play an important role in chemical, petroleum, pharmaceutical, power, food, energy and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc. ,Wide range of applications. [0003] The heat exchanger in the prior art often relies on the flow of the heat exchange medium (condensation medium) itself to take away the heat of the material, so as to achieve the effect of cooling the material. The fluidity of the heat exchange medium in this way is too low , part of the heat exchange medium does not even come...
