With the rapid growth of my country's industrialization, the demand for energy is increasing day by day, and the rapid economic development also leads to an imbalance in sustainable development. Saving resources and reducing energy consumption are the primary tasks of socialist construction at present. The energy consumption of industry is relatively large compared with other industries. From the perspective of the country and enterprises, if we want to take the road of sustainable development, we must use less resources to obtain large economic benefits, which will not only promote the development of enterprises, but also make Energy has been fully utilized, and it has also promoted the steady progress of my country's energy conservation and emission reduction cause.
Industrial kilns operate under heavy load and alternating slow speed at high temperature, and the maintenance of their accessories and the control level of thermal system are related to the operation and efficiency of the kiln. Different types of kilns have the problem of high temperature insulation under normal working conditions. The loss of a large amount of heat results in a large amount of energy waste, which greatly shortens the life of the kiln. The external components are used for a long time at high temperatures, and there are great hidden dangers. . Therefore, in order to achieve the purpose of energy saving, industrial furnaces should first consider saving energy and make full use of it. The furnace body dissipates heat energy by heat conduction. In order to reduce the heat loss of the furnace body, an insulating layer is added inside the furnace body. The heat insulating material selected for the heat insulating layer directly determines the energy saving efficiency of the industrial furnace.
In recent years, a lot of in-depth research on refractory insulation materials has been carried out at home and abroad, and a variety of materials have been successfully developed, such as glass wool, mineral wool, microporous calcium silicate, composite silicate, closed-cell expanded perlite, ceramics Fiber, etc., to achieve high temperature resistance, low thermal conductivity, thermal shock resistance, flame retardant, and can slow down the industrial demand for heat loss caused by heat conduction, heat convection, etc. Most refractory insulation materials are loose and porous, and the voids in the material account for a large proportion. When they come into contact with moisture, they will absorb a lot of water. Since the thermal conductivity of water is much greater than that of air, it will seriously affect the thermal insulation performance of the material. Its own hydrophobicity is an important indicator for judging the performance of materials.
Aerogel thermal insulation material, Class A fireproof, temperature resistance up to 1800°C, high hydrophobicity (≥99%), with special treatment for infrared shielding and reflection, it is attached to the surface of the furnace body and has a strong isolation of infrared rays It can prevent the conduction and transmission of high-temperature thermal electromagnetic waves, effectively reduce the amount of heat absorbed by the object per unit time, and reduce the surface temperature of the object. By increasing the thickness of the aerogel material, the radiation energy level can be increased to the greatest extent, and the radiation degree of the heat energy can be increased when the heat energy is effectively stored, and the heat energy utilization rate can be improved in both directions, and the energy saving effect is better and obvious.
