[0001] This invention relates to the field of aluminum plating machine technology, and more specifically, to a high-efficiency and environmentally friendly aluminum plating machine device that also features waste heat recovery and utilization. Background Technology

[0002] In the aluminizing process, heat exchangers are widely used to recover and utilize the waste heat generated during the aluminizing process. These heat exchangers transfer waste heat to other media through conduction and convection to improve energy efficiency. However, heat exchangers in the existing technology usually rely on fixed parameters for operation and lack real-time feedback and adjustment mechanisms, resulting in low heat recovery efficiency. In addition, the heat requirements of each process step in the aluminizing process are different, but the existing system cannot flexibly adjust the heat distribution, often resulting in some steps having too much heat and others having insufficient heat.

[0003] The main pain points and shortcomings of existing technologies are as follows: First, traditional heat exchangers lack real-time data acquisition and dynamic adjustment capabilities, and cannot effectively adjust according to the actual recovered heat and set targets, resulting in low waste heat recovery efficiency and high energy consumption; second, the heat distribution system is not intelligent enough and cannot be dynamically adjusted according to the needs and priorities of each process link, resulting in uneven resource utilization and affecting production efficiency and stability. In order to solve these problems, this invention proposes a high-efficiency and environmentally friendly aluminizing machine device that combines waste heat recovery and utilization. By acquiring data in real time and intelligent adjustment, the waste heat recovery efficiency is improved, and the dynamic distribution of heat is achieved through intelligent valves and pipeline systems to optimize resource utilization.

It is the first The priority of each process step; the larger the value, the higher the priority. The waste heat used in each process step is calculated using the formula. Calculate the heat distribution for each process step. ,in It represents the weighted sum of the priority and heat demand of all process steps. Through the electronically controlled valves and pipeline switching system, the waste heat is dynamically allocated according to the calculation results to ensure that each process step obtains the required heat first.
