Description

Technical Field

[0001] This utility model relates to the technical field of heat exchange equipment, specifically to energy-saving heat exchange equipment for coal chemical industry. Background Technology

[0002] A heat exchanger is a device that transfers some of the heat from a hot fluid to a cold fluid; it is also called a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food, and many other industrial production processes. In chemical production, they are widely used as heaters, coolers, condensers, evaporators, and reboilers.

[0003] The coal chemical industry uses heat exchangers to improve energy efficiency, ensure safe and stable production, promote environmental protection and sustainable development, and drive technological innovation and industrial upgrading.

[0004] In heat exchangers, there are graphite heat exchangers. In existing graphite heat exchangers, the heat exchange channels on both sides of the heat exchange block are relatively short, while the heat exchange channel in the middle is relatively long. As a result, the heat exchange liquid passing through the channels on both sides will pass through the heat exchange block quickly, which leads to incomplete heat exchange. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an energy-saving heat exchange device for coal chemical industry, which solves the problems mentioned in the background.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a coal chemical energy-saving heat exchange equipment, including a shell, two retaining rings provided on the inner side wall of the shell, two retaining rods fixed between the two retaining rings, a plurality of arc-shaped partition rods provided between the two retaining rings, the two ends of the arc-shaped partition rods being fixedly connected to the two retaining rods respectively, a heat exchange block being provided inside the arc-shaped partition rods, and sealing covers being fixed on both the left and right sides of the shell;

[0007] A heat exchange medium pipe is fixed to the outer wall of the sealing cover, and two heat exchange liquid pipes are fixed to the outer wall of the shell. Multiple rotating rods are rotatably connected between the two retaining rings. The rotating rods pass through multiple arc-shaped partition rods and are rotatably connected to the arc-shaped partition rods. Multiple fixed cylinders are fixed to the outer wall of the arc-shaped partition rods, and multiple blades are fixed to the outer wall of the fixed cylinders.

[0008] Preferably, the left-side sealing cover has a drive mechanism inside, and the drive mechanism has multiple transmission rods rotatably connected inside. The transmission rods are located inside the left-side sealing cover and are rotatably connected to the sealing cover.

[0009] Preferably, a rotating block is rotatably connected to the inside right side of the sealing cover. A storage hole is provided at the right end of the rotating block. A spring is fixed inside the storage hole. An insert block is fixed at the other end of the spring. The left end of the rotating rod passes through the left retaining ring. An insert hole is provided at the left end of the rotating rod. The transmission rod and the rotating block are connected by a first bevel gear.

[0013] Beneficial effects

[0014] This utility model provides an energy-saving heat exchange device for coal chemical industry. Compared with the prior art, it has the following advantages:

[0015] 1. This coal chemical energy-saving heat exchange equipment is equipped with a rotating rod, a fixed cylinder, and blades. The rotation of the rotating rod will cause the fixed cylinder and blades to rotate, and the blades will agitate the liquid that needs to exchange heat. This allows the liquid that has not been thoroughly heated at the top and bottom to exchange heat with the liquid that has been thoroughly heated in the middle of the heat exchange block, so that the liquid that has been thoroughly heated can be conducted and diffused.

[0016] 2. This energy-saving heat exchange equipment for coal chemical industry, by setting up a drive mechanism, uses the heat exchange medium to impact the fan blades, which causes the round rod, transmission rod and rotating block to rotate. The rotating block drives the rotating rod to rotate through the insert block, so no additional energy is needed when stirring the liquid that needs heat exchange. Attached Figure Description
