Problems solved by technology

[0003] At present, thermal desorption and additional heating equipment is mainly composed of heating containers, fans, heating devices and other components; among them, the existing heating devices mainly use combustion heating or microwave heating, but combustion heating has long heating time and high energy consumption. , low desorption efficiency and other problems, and the use of microwave heating has problems such as uneven heating and easy flash point. Therefore, the existing thermal desorption and heating equipment has poor repair effect on oily soil and is very unstable.

Embodiment approach

[0026] (1) Since the oily soil is placed in the lower part of the casing 2 (whether it is figure 1 inside the heating tank 7, or figure 2 On the conveyor belt 61 in the middle, the oily soil is all in the lower part in the housing 2, even if the heating tank 7 rotates, most of the oily soil is also in the lower part in the housing 2 under the action of gravity), and the microwave heating device 3 and ultrasonic dispersion Device 4 all penetrates casing 2 (and figure 1 The heating tank 7) in the oily soil directly acts on the oily soil, so the microwave heating device 3 and the ultrasonic dispersing device 4 are fixed on the top of the housing 2, so that the oily soil can be maintained between the microwave heating device 3 and the ultrasonic dispersing device 4. A certain distance, which not only helps the microwave heating device 3 directly heat the inside of the oily soil to make the heating more uniform, but also helps the ultrasonic dispersing device 4 to disperse the co...

Abstract

The invention discloses a thermal desorption heating device for oily soil restoration. The thermal desorption heating device structurally comprises a microwave heating device (3), an ultrasonic dispersion device (4) and an infrared heating device (5). Both the microwave heating device (3) and the ultrasonic dispersion device (4) are fixed to the top of a shell (2). The microwave heating device (3) is located on the left side of the ultrasonic dispersion device (4), and the infrared heating device (5) is fixed to the bottom of the shell (2). In the oily soil heating process, oily soil placed on the lower portion in the shell (2), the ultrasonic dispersion device (4) is switched on, the infrared heating device (5) is used for heating the oily soil to a preset temperature firstly, and then the microwave heating device (3) is switched on for heating. The thermal desorption heating device can effectively keep the stability and the evenness of heating and greatly improve the oil soil restoration effect and is simple in structure, low in energy consumption and wide in application range.

Description

technical field [0001] The invention relates to the technical field of oily soil remediation, in particular to a thermal desorption and heat addition equipment for oily soil remediation. Background technique [0002] Thermal desorption technology is a technology that desorbs volatile substances from non-volatile substances by direct or indirect heating, and it is one of the effective technologies for remediating polluted soil. Different from incineration, the thermal desorption technology does not decompose the organic pollutant components, but heats the organic pollutant components in the soil to volatilize through direct or indirect heating, so that the organic pollutant components are separated from the soil and achieve the purpose of remediating the soil. Purpose. The research and application results show that thermal desorption technology has a good remediation effect on oily soil remediation. [0003] At present, thermal desorption and additional heating equipment is...
