Problems solved by technology

However, due to the low dielectric constant value of the soil, its ability to gather microwave energy is weak. Therefore, when heating with existing equipment, the soil temperature rises slowly and the heating efficiency is low, which affects the removal rate of organic pollutants and increases soil microwave thermal desorption. Energy consumption, high cost of use

Abstract

The invention discloses a material box for microwave heating, and relates to the field of microwave heating. Electrodes are arranged on the lower bottom surface of a box body. According to the resonant cavity theory and the medium perturbation theory, the electrodes are added into the material box, electromagnetic field distribution is improved, and electromagnetic field energy is evenly gathered in the material box. The material box can be used for heating soil and other materials with poor medium characteristics and weak microwave absorption characteristics, the temperature rise rate can be effectively increased, the treatment period is shortened, and heating energy consumption is reduced. The material box has wide popularization and application values in the application fields of environmental protection, chemical materials, mining and metallurgy products and the like.

Description

technical field [0001] The invention relates to the field of microwave heating, in particular to a material box for microwave heating. Background technique [0002] With the application of microwave heating technology more and more widely, there are more and more types of materials to be heated. For example, materials with low dielectric constant values ​​such as soil have weak ability to gather microwave energy, which means that such materials are During microwave heating, the energy density of the internal electromagnetic field is low, and the temperature of the material rises slowly, which affects the heating efficiency. [0003] Applying microwave technology to the field of environmental protection, heating the organic polluted soil with a certain thickness can make the organic pollutants heat up, gasify and volatilize and separate from the soil, so as to achieve the purpose of repairing the soil. However, due to the low dielectric constant value of the soil, its abilit...
