The main control unit is also connected to an electromagnetic three-way valve. One end of the electromagnetic three-way valve is connected to the main steam pipeline, one end is connected to the main steam pipeline, and one end is connected to the water washing storage tank.

[0013] This application uses a main steam pipeline as the primary heating stage, outputting steam to the tank through a steam generator; it uses an annealing waste heat system as the secondary heating stage, recovering waste heat and transferring it to the tank through a heat exchanger; finally, it uses a finned tube heat exchanger as the tertiary heating stage, which is connected to the main steam pipeline. The low-temperature steam and condensate generated after heating the air are directly discharged into the water washing storage tank through the pipeline. Ultimately, this application has multiple heating sources, which improve heating efficiency in combination, and the positions of the multiple heating sources are set to make the heating in the tank more uniform.

[0018] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] Please refer to Figure 1-3 As shown in the first embodiment, a high-efficiency waste heat utilization water washing storage tank system includes an annealing waste heat system 1, a plate heat exchanger 2, a steam main pipeline 3, a water washing storage tank 4, a finned tube heat exchanger 5, and a water washing tank 6, wherein the water washing storage tank 4 is connected to the water washing tank 6.

[0020] The annealing waste heat system 1 is connected to one end of the plate heat exchanger 2. The other end of the plate heat exchanger 2 recovers waste heat from the water washing storage tank 4 on one side and outputs heat to the water washing storage tank 4 on the other side.

[0021] The main steam pipe 3 outputs steam to the water washing storage tank 4;

[0022] The finned tube heat exchanger 5 receives steam from the main steam pipe 3, heats it, and then outputs it back to the water washing storage tank 4.

[0023] This application uses a main steam pipeline as the primary heating stage, outputting steam to the tank through a steam generator; it uses an annealing waste heat system as the secondary heating stage, recovering waste heat and transferring it to the tank through a heat exchanger; finally, it uses a finned tube heat exchanger as the tertiary heating stage, which is connected to the main steam pipeline. The low-temperature steam and condensate generated after heating the air are directly discharged into the water washing storage tank through the pipeline. Ultimately, this application has multiple heating sources, which improve heating efficiency in combination, and the positions of the multiple heating sources are set to make the heating in the tank more uniform.

[0024] Embodiment 2 also includes a main control unit for controlling the operation of each module, and multiple temperature sensors disposed at multiple locations in the water washing storage tank 4 for detecting the temperature at several locations;

[0025] It also includes electric valves and electric pumps connected to several branches of the main steam pipeline 3.

[0026] First, several branches of the main steam pipeline extend to multiple locations within the tank. Temperature sensors are installed at the corresponding locations of each branch to provide real-time feedback of the current temperature value to the main control unit. Then, the main control unit adjusts the electric valves and electric pumps based on the feedback information to regulate the steam volume and thus control the heating effect.

[0027] In Embodiment 2, a detection unit for detecting whether several modules are working properly is further included. The detection unit is connected to the main control unit. The main control unit is also connected to an electromagnetic three-way valve. One end of the electromagnetic three-way valve is connected to the main steam pipeline 3, and the other end is connected to the water washing storage tank 4.

[0028] In this embodiment, reference Figure 3 Taking the main steam pipeline and the annealing waste heat system as an example, the main steam pipeline is configured with a branch connected to point 1 of the three-way solenoid valve, the pipeline of the annealing waste heat system is connected to point 2, and point 3 outputs to the tank. The detection unit can be a sensor to detect whether the annealing waste heat system is working properly. If it is working properly, the main control unit sends a signal to connect points 2 and 3. In this way, the main steam pipeline heats the tank with steam, and the annealing waste heat system supplies heat energy to the tank through the three-way valve. When the annealing waste heat system malfunctions, points 1 and 3 are connected. In addition to working, the steam pipeline itself also uses the solenoid three-way valve to heat the tank with steam through the pipeline. This can achieve uninterrupted operation and prevent the impact on work efficiency.

[0029] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
