[0002] Waste heat in the cement industry refers to the large amount of low-grade heat energy generated during cement production, mainly from clinker cooling, kiln exhaust gas, and equipment heat dissipation.

The heat lost during the cooling process is generally not collected, which results in a waste of energy resources.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0023] This embodiment provides a waste heat exchange device for the cement industry, mainly used to address the problem that after cement clinker is produced, it generally needs to be rapidly cooled inside a cooling device. The heat lost during this cooling process is usually not collected, resulting in a waste of energy resources. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-4 Please provide a detailed explanation:

[0024] A waste heat energy exchange device for cement industry includes: a pair of mounting brackets 1 with adjusting pipes 2 mounted on the surface; a receiving space 3 (with an inlet 5 and an outlet 6) and an energy exchange space 4 (with a water inlet 7 and an outlet 8) are formed on the inner wall of the adjusting pipes 2. Therefore, in use, the user first needs to introduce cement clinker into the receiving space 3 through the inlet 5 and cold water through the inlet 7. Then, the driving unit 9 drives the cement clinker inside the receiving space 3 to move along the length of the receiving space 3. The heat energy inside the cement clinker will quickly heat the cold water. Finally, the heated cold water is discharged from the outlet 8, thus completing the energy exchange of the heat energy in the cement clinker (this hot water can be subsequently fed into a steam turbine for power generation). The cement clinker is discharged from the outlet 6 and enters the cooling device (existing technology) for the next process. The device also includes an adjusting unit 10 for adjusting the adjusting pipes. The tilt angle of the adjustment tube 2 is as follows: the main components of the drive unit 9 are: a drive motor 92 fixedly installed on the surface of the adjustment tube 2, and an auger 91 rotatably installed on the inner wall of the accommodating space 3. In use, the user controls the output end of the drive motor 92 to rotate through the controller 93, which drives the auger 91 fixedly installed on the output end of the drive motor 92 to rotate, thereby driving the cement clinker inside the accommodating space 3. The main components of the adjustment unit 10 are: a hydraulic rod 102 rotatably installed on the surface of the mounting frame 1, and a fixing frame 101 fixedly installed on the surface of the adjustment tube 2. In use, the user controls the extension and retraction of the hydraulic rod 102 through the controller 93, which drives the adjustment tube 2 rotatably installed on the other end of the hydraulic rod 102 to rotate. During this process, the fixing frame 101 rotates at the same time, thereby adjusting the tilt angle of the adjustment tube 2 (the speed at which the cement clinker slides on the inner wall of the accommodating space 3).

[0025] By installing an adjusting pipe 2 on the surface of the mounting frame 1, and having a receiving space 3 and an energy-converting space 4 on the inner wall of the adjusting pipe 2, the user puts cement clinker into the receiving space 3 through the inlet 5 on the inner wall of the receiving space 3 during use. External cold water is introduced into the energy-converting space 4 through the inlet 7 on the inner wall of the energy-converting space 4. Then, the cement clinker is driven to slide on the inner wall of the receiving space 3 by the drive unit 9, so as to realize the transportation of cement clinker and the rapid heating of cold water (energy conversion). After the energy conversion is completed, the hot water is discharged from the outlet 8 on the inner wall of the energy-converting space 4, and the cement clinker is finally discharged from the outlet 6 on the inner wall of the receiving space 3 and enters the cooling device (existing technology) for cooling.

[0026] like Figure 1 and Figure 4As shown, in some embodiments, several maintenance slots 11 are formed on the inner wall of the receiving space 3. Baffles 12 are slidably inserted into the inner wall of each maintenance slot 11. During use, the user needs to use the limiting unit 13 to restrict the baffles 12 to the inner wall of each maintenance slot 11, thereby blocking the maintenance slots 11. When cleaning the inner wall of the receiving space 3 is required, the user can remove the baffles 12, allowing the user to clean the inner wall of the receiving space 3 through the maintenance slots 11. The main components of the limiting unit 13 are: several limiting bolts 132, and limiting edges 131 are fixedly installed on the inner walls of several maintenance slots 11. In use, the user needs to slide several baffles 12 into the inner walls of several maintenance slots 11 in sequence, then thread the surfaces of several limiting bolts 132 onto the surfaces of several baffles 12, and finally thread them into the surfaces of several limiting edges 131 in sequence, so as to limit the several baffles 12 on the inner walls of several maintenance slots 11.

[0027] By opening several maintenance slots 11 on the inner wall of the accommodating space 3, during use, the user can use the limiting unit 13 to restrict several baffles 12 to the inner wall of several maintenance slots 11 respectively, thereby blocking several maintenance slots 11. Subsequently, the limiting unit 13 can be used to open several baffles 12 to clean the inner wall of the accommodating space 3.

[0028] like Figure 2 and Figure 4 As shown, in some embodiments, steel pipes 14 are fixedly inserted into the inner walls of the feed inlet 5, water inlet 7, and water outlet 8 (each of the steel pipes 14 is equipped with a solenoid valve 16, which can be controlled by the controller 93). At the same time, stainless steel corrugated pipes 15 are fixedly inserted into the other end of each of the steel pipes 14. In use, the user can connect the external cement clinker outlet, cold water outlet, hot water inlet of power generation equipment such as steam turbine to the stainless steel corrugated pipes 15 in sequence (there are various connection methods, such as welding or flange connection).

[0029] The working process of this utility model is as follows:

[0030] First, the user needs to pass cement clinker into the interior of the containment space 3 and cold water into the energy exchange space 4. After the cold water is heated into hot water, it can be discharged from the outlet 8 into the interior of the steam turbine and other power generation equipment to generate electricity.

[0031] Secondly, in the above process, the heat energy of cement clinker is not only recovered, but also the transportation of cement clinker is realized, thus achieving the rational recovery of the heat energy of cement clinker.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
