Renewable energy comprehensive utilization system of sewage plant

Abstract

The invention discloses a renewable energy comprehensive utilization system of a sewage plant. The system comprises a photovoltaic power generation system and a sewage heat source heating and refrigerating system, the photovoltaic power generation system supplies power to sewage treatment, the sewage heat source heating and refrigerating system and a municipal power grid, and the sewage heat source heating and refrigerating system supplies cold and heat sources to a sewage plant. According to the invention, the solar energy of a sewage plant and the waste heat of municipal sewage are fully utilized; according to the electric energy consumption and photovoltaic power generation characteristics of a sewage plant, a photovoltaic power generation installed capacity optimal model is established, solar energy is fully utilized, the electric energy consumption of the sewage plant is reduced, meanwhile, the construction cost of photovoltaic equipment is saved, and environmental pollution caused by coal-fired power generation is reduced. Meanwhile, the seasonal temperature change characteristic of municipal sewage is utilized, the sewage supplies cold and heat to the sewage plant, energy consumption of the sewage plant is further reduced, and renewable energy sources of the sewage plant are fully utilized.

Description

technical field [0001] The invention relates to the technical field of utilization of renewable energy in sewage plants, in particular to a comprehensive utilization system for renewable energy in sewage plants. Background technique [0002] Under the grim situation of continuous growth in energy demand and increasing shortage of energy supply, more and more attention has been paid to renewable energy due to its ability to be recycled without human participation. The development and utilization of renewable energy will become an important issue in the energy field. research and development directions. [0003] Sewage plants in cities are mainly used to treat waste water that cannot be discharged directly, such as municipal sewage, but municipal sewage is also a high-quality low-temperature heat source, which contains waste heat in the process of life and production, and the annual flow rate changes little and is relatively stable , the temperature of municipal sewage is low...

AI Technical Summary

Problems solved by technology

However, traditional sewage plants cannot effectively utilize the waste heat of municipal sewage. The same sewage plants have very limited use of renewable energy such as solar energy, resulting in energy waste. Therefore, it is necessary to develop a renewable energy utilization system for sewage plants to realize Maximization of Renewable Energy Utilization in Wastewater Plants
