Technical energy saving and process energy saving are direct energy saving methods, and the following methods can be adopted from the technical and process ways of energy saving: improving the efficiency of energy transfer and conversion equipment, reducing the number of conversions and the distance of transmission; Rational use of energy according to the quality of energy, as far as possible to prevent the downgrading of high-quality energy; In accordance with the principle of system engineering, the electricity, hydropower, heat energy, waste heat and residual pressure of the entire enterprise or regional energy-using system are fully utilized to maximize energy utilization.
The general energy-saving technologies that organically combine energy saving and environmental protection are as follows:
High-efficiency and low-pollution combustion technology
According to the characteristics of the combustion of different fuels such as gas, oil, and coal, various measures are adopted to improve the combustion efficiency of fuels.
Enhanced heat transfer technology
The heat transfer process is divided into three basic modes: heat conduction, convective heat transfer and radiation heat transfer, which are effective energy-saving technologies to reduce the power consumption and enhance the thermal conductivity in the heat transfer process.
Waste heat ** technology
It is an advanced technology that achieves energy conservation through direct utilization, power generation and comprehensive utilization of six types of waste heat, including high-temperature flue gas waste heat, combustible exhaust gas, waste liquid, waste heat of waste materials, waste heat of high-temperature products, waste heat of chemical reactions, waste heat of cooling medium, waste gas and waste water.
Thermal insulation technology
The equipment and pipe network in the process of heat conversion, transmission and use are insulated with lightweight ceramic fiber insulation materials to reduce heat loss, save fuel and meet user requirements.
Heat pump technology
A heat pump is a device that utilizes the ability to transfer heat from a cold object to a high temperature object, which can extract heat from the environment for heating. This is a technology that consumes a small amount of mechanical energy but provides a large amount of heat for heating, and heat pump technology.
Heat pipe technology
It refers to the technical method of using new heat transfer elements to strengthen heat transfer and energy saving.
Air cooling technology
Direct and indirect air cooling technologies are used to address traditional cooling technologies such as increased energy consumption caused by water cooling, increased consumption of precious fresh water, environmental pollution caused by water cooling, and sharp increase in operating costs.
Solvent** technology
It is to extract the organic solvent air mixture gas volatilized into the air, and through the operation of a certain device (such as: absorption method, freeze condensation method, solid adsorption method, etc.), the solvent gas is intercepted, and the exhaust gas that meets the emission standards is discharged into the atmosphere. The trapped solvent gas can be reused in production after fractionation, purification and other preparation methods. Therefore, solvent technology is a practical technology that is both environmentally friendly and cost-saving.
