[0001] The invention relates to the field of ship equipment design and development, and in particular to a low-carbon design method for ship sewage treatment equipment. Background Art

[0002] Intelligent design and low-carbon transformation are two important directions for the development of the shipbuilding industry. As a key technology in the field of ship design, intelligent parametric design realizes automation and optimization of design through parametric modeling, which greatly improves design efficiency and quality. In ship design, intelligent parametric design allows designers to define a set of parameters to control different aspects of the design, thereby achieving rapid iteration and automated design process. In addition, intelligent parametric design supports full life cycle management, from conceptual design to production and manufacturing, ensuring the consistency and traceability of the design, and providing the possibility for carbon footprint calculation and evaluation of the equipment life cycle.

[0003] Current equipment carbon footprint research focuses on the environmental impact assessment of the entire life cycle, focusing on the efficient energy use, material selection, manufacturing process optimization, intelligent control system, and energy recovery technology of the equipment. Eco-design principles are increasingly considered in the design process to achieve low-carbon goals for equipment in the production, use, and disposal stages. Integrate the current status of equipment carbon footprint research into the entire design process of ship sewage treatment equipment, reduce material use, and optimize equipment shape and structure to reduce weight and space requirements. In addition, modular and integrated design is adopted to improve production efficiency, reduce assembly time and cost, and simplify the maintenance and upgrade process of the equipment. Summary of the invention

[0004] The purpose of the present invention is to provide a low-carbon design method for ship sewage treatment equipment. By constructing an equipment parameter design method and process, an automatic calculation method for the carbon footprint of the equipment is integrated into the design process to adapt to different types of ship sewage treatment technical routes, so as to achieve low-carbon and intelligent design process, and improve the green and low-carbon level of ship sewage equipment while improving the design efficiency.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] A low-carbon design method for ship sewage treatment equipment, including a sewage treatment equipment module parameterization design method and an equipment carbon footprint calculation and evaluation method.

[0007] The sewage treatment equipment module parametric design method includes cabinet design parameterization, model generation, and design result output. The cabinet design parameterization refers to the cabinet module parameters and layout design of the regulating cabinet, aerobic cabinet, anaerobic cabinet, clean water cabinet, and membrane cabinet of the sewage treatment equipment; model generation refers to the establishment and assembly of the UG NX model through parameter expressions; design output refers to the output of the equipment three-dimensional model and the content of the detailed list;

[0008] The equipment carbon footprint calculation and evaluation method includes the calculation of the equipment cabinet carbon footprint, the process carbon footprint calculation and the calculation output. The equipment cabinet carbon footprint calculation refers to the sub-item calculation of the carbon footprints of various materials used in the equipment. The process carbon footprint calculation is the calculation of the carbon footprint generated during the degradation process of pollutants in the sewage treatment process. The calculation output refers to the method of outputting the equipment carbon footprint in combination with the equipment parameterization table and the carbon footprint calculation method.

[0009] Furthermore, the sewage treatment equipment module parametric design method has the following specific steps: first, UG NX is used to perform three-dimensional modular design and modular decomposition of the equipment; then, the product rapid design based on the three-dimensional design management platform automatically drives the driving parameters of the background parametric digital model by adopting parameters to realize the cabinet design parameterization; finally, the design results are output, including the output of the equipment three-dimensional model and the content of the detailed list.

[0010] Furthermore, the drive parameters come from the key parameters defined by the user on the program interface, and the parameters automatically calculated or verified by the program according to the background calculation formula and logic, wherein the device parameters are automatically adjusted as the data table is adjusted.

[0011] Furthermore, the equipment carbon footprint calculation and evaluation method has the following specific steps: first, a carbon emission model is established. Combined with the composition of the ship domestic sewage treatment equipment, the carbon emission model of the domestic sewage treatment equipment during its life cycle is:

[0012] Z=Z pr +Z tr +Z ru +Z re

[0013] Carbon emissions in the manufacturing stage are divided into carbon emissions from material production and carbon emissions from equipment processing. The carbon emission model is:

[0014]

[0015] Where Z is the total carbon emissions during the life cycle, in kg;

[0016] Z pr —Carbon emissions during the manufacturing phase, in kg;

[0017] Z tr—Carbon emissions during the transportation phase, in kg;

[0018] Z ru —Carbon emissions during the operation and maintenance phase, in kg;

[0019] Z re —Carbon emissions during the scrapping and recycling phase, in kg;

[0020] Z pr,j —The jth carbon emission in the manufacturing stage, in kg;

[0021] m i —The mass of the i-th material used in the manufacturing stage, in kg. The main components of the MBR (C) -200 domestic sewage treatment equipment are all made of Q25 steel;

[0022] z i,j —The emission coefficient of the jth pollutant of the i-th material used in the production stage. The carbon emission coefficients of different materials are shown in Table 1;

[0023] m k —The mass of the kth component at the manufacturing stage, in kg;

[0024] q k —The power consumption per unit mass of the k-th component during the manufacturing phase is 0.12 kWh / kg;

[0025] z e,j —Emission coefficient of the jth pollutant per unit of electricity consumption;

[0026] Then, according to the above carbon emission calculation method, the different carbon emissions in the production stage and operation stage of the domestic sewage treatment equipment during its entire life cycle are calculated;

[0027] Finally, the equipment parameterization table and carbon footprint calculation method are combined to output the equipment carbon footprint.

[0028] Furthermore, in the calculation of carbon emissions, the conversion of other pollutants into carbon dioxide is achieved through the global warming potential, the factor by which different pollutants are converted into carbon dioxide.

[0029] Furthermore, during the operation stage, the carbon emissions generated by equipment power consumption, carbon emissions generated by operating processes, and indirect carbon emissions generated by the addition of chemical agents are calculated using a product method similar to that of the production and manufacturing stage.

[0030] The beneficial effects of the present invention are:

[0031] A low-carbon design method for ship sewage treatment equipment of the present invention reflects the carbon footprint level of the equipment design process in real time through an intelligent and low-carbon design process for ship sewage treatment equipment. The product design can be quickly modified by modifying the cabinet parameters of the sewage treatment equipment, and the carbon footprint of the equipment is generated accordingly, which reduces the dependence on manual calculations, can quickly respond to market changes and customer needs, and improve the market competitiveness of products and enterprises. The method integrates the parametric design module of the sewage treatment equipment module and the equipment carbon footprint calculation and evaluation module, and integrates the carbon footprint evaluation method and low-carbon thinking into the design process of ship equipment, which complies with the requirements of documents such as the "Action Program for Green Development of Shipbuilding Industry (2024-2030)" and the "Implementation Plan for Establishing a Carbon Footprint Management System" issued by the state.
