Design and plan the construction and operation of the power plant according to the client's needs (site size, budget, fuel (mainly local waste and sludge) parameters, etc.). Provide the customer with a variety of combustion furnace types, design the matching storage and feeding methods, as well as the dimensions and types of combustion furnace components, and give the construction and operation costs of the plant and its power generation through the calculation and analysis of the operating temperature of the combustion chamber and the composition of the exhaust gases.

Based on the calculated exhaust gas parameters, a number of alternative exhaust gas treatment options are developed for each combustion furnace to meet the requirements of local laws and regulations for waste treatment power plants. Calculation of the construction and operating costs of each option, as well as the parameters of the treated exhaust gases.

Taking all of the above into account, the customer is offered a number of options to consider and choose from.

Design non-standard automated mechanical production equipment and production process lines according to the requirements put forward by customers. The business is mainly for labor-intensive enterprises, to achieve the mechanization and automation of the original manual assembly line, for customers to reduce labor costs and improve production efficiency. During the internship, the following products were designed:

• Fully automatic air nail gun nailer for the production of cat crawler paper tube and the matching automatic rope winding machine, the
• a fully automatic assembly line for assembling cosmetic pressing pumps.
• Automatic gluing machine for hot melt glue machine, etc.

Automated control of a metal smelting process in an electric arc furnace based on multiple sensing signals, which includes, among other things, automation of electrode expansion and contraction based on the height of the melting pool, automation of power adjustment of the equipment based on the melting process, automation of cooling water circulation based on the temperature of the furnace and the electrodes, and automation of waste gas treatment based on the temperature of the exhaust gas and the composition of harmful gases in the exhaust gas. Based on multiple sensing signals characterizing the working state of the electric arc furnace, and taking into account factors such as energy utilization, working efficiency and pollutant generation, the online control and precise adjustment of different operating parameters are realized, which optimizes the process flow and improves energy efficiency and economic benefits.

The coupling characteristics of interstitial electric field and flow field in gas-assisted high-efficiency electric discharge molding machining were investigated. Different kinds of gases, such as air, oxygen, nitrogen and helium, are mixed into the traditional water-based working fluid to suppress the strong electrolytic reaction between the electrode and the workpiece caused by the water-based working fluid due to the high conductivity, and to reduce the energy loss and improve the stability of the machining process. The coupled model of electric field and flow field is constructed by the finite element method to analyze the effect of bubble diameter on the electric field strength and potential distribution. Based on the simulation results, the machining speed, precision and stability are optimized by controlled experiments, which significantly improve the efficiency of the machining process.
