Novel energy system for recycling chemical waste heat and scheduling method thereof

Abstract

The novel energy system comprises a waste heat recovery module, the waste heat recovery module comprises a micro gas turbine, a waste heat boiler, an isolation sewage disposal unit, a heat collection water tank, a heat pump and a waste heat conversion device, and the waste heat conversion device comprises a heat exchanger and a refrigerating machine; the micro-gas turbine absorbs natural gas to generate electrical load and flue gas, the waste heat boiler recycles and stores the flue gas generated by the micro-gas turbine and transmits redundant flue gas to the heat exchanger, the heat collection water tank absorbs solar energy, and when the water temperature reaches a preset temperature, water in the heat collection water tank is transmitted to the heat exchanger. The isolation and decontamination unit carries out isolation and decontamination on the chemical wastewater and then sends the chemical wastewater to the heat pump, and the heat pump conveys the treated chemical wastewater to the heat exchanger. The heat exchanger generates a heat load according to the received waste heat, and meanwhile the heat exchanger transmits the redundant waste heat to the refrigerating machine to generate a cold load. The waste heat recovery efficiency of the system is fully improved, and heat loads and cold loads required by chemical plants can be supplied.

Description

technical field [0001] The invention belongs to the field of energy saving and environmental protection. Background technique [0002] In the context of scrambling to pursue clean energy, fossil energy is being replaced step by step, which is also the result of the depletion of primary energy. In the future trend of the times, renewable energy such as wind power, solar energy, and water energy will gradually increase their status in the energy field. [0003] In this way, various energy systems using clean energy are designed and put into use. As an important part of the distributed energy system field, the cogeneration system of cooling, heating and power is gradually accepted by people and widely used for its small footprint and high safety and stability. [0004] As a distributed power supply system, the combined cooling, heating and power system has obvious advantages. Due to its small footprint, the construction site can be flexibly selected. Moreover, the system ca...

AI Technical Summary

Problems solved by technology

However, the system still has shortcomings

It is not sufficient for waste heat recovery. The traditional cooling and heating power system only relies on the waste heat boiler to absorb and utilize flue gas, and the recovery effect is not sufficient.

Second, excess load cannot be stored

Finally, the system only includes natural gas and grid as energy input, not enough diversification
