Problems solved by technology

Aiming at different types of pollution in China, researchers have developed a series of remediation technologies from the three directions of physics, chemistry and biology, but the research on remediation equipment is almost blank
[0003] Among the many types of soil pollution, one of them is organic pollution. After toxic and harmful organic substances enter the soil, their quantity and speed exceed the speed of soil purification, destroying the natural dynamic balance and gradually occupying the accumulation process of pollutants. Advantages, which lead to the normal dysfunction of the soil, the decline of soil quality, and affect the growth and development of crops, as well as the decline of yield and quality

Embodiment 1

[0021] Please refer to figure 1 As shown, a pyrolysis device for repairing contaminated soil includes a feed device 2 , a discharge device 3 , a soil pyrolysis device 1 , a transmission device 4 , a pyrolysis gas absorption and treatment device 5 and a gas supply device 6 .

[0022] The soil pyrolysis device 1 includes a heating furnace body 11 with a heating chamber inside and a pyrolysis cylinder 13 .

[0023] An opening communicating with the heating chamber is provided at the center of the left and right ends of the heating furnace body 11 . The top end of the heating furnace body 11 is provided with an air outlet 17 , and the bottom end of the heating furnace body 11 opposite to the air outlet 17 is provided with an air inlet 16 . The heating furnace body 11 is provided with a furnace body insulation layer 12 , and the bottom of the heating furnace body 11 is provided with an electric heating element 14 .

[0024] The pyrolysis cylinder 13 is arranged in the heating fur...

Embodiment 2

[0030] Please refer to figure 2 As shown, when the moisture content in the soil is high, the energy consumption of soil pyrolysis restoration will increase. In order to ensure a good pyrolysis effect, the soil pyrolysis device 1 described in Example 1 is set to two stages. Specifically: connect the discharge device 3 of the primary soil pyrolysis device 1 with the feed device 2 of the secondary soil pyrolysis device 1; connect the pyrolysis gas outlet 1817 of the primary soil pyrolysis device 1 with the secondary soil After the pyrolysis gas outlet 1817 of the pyrolysis device 1 is connected, it is collected in a connecting pipe, and the connecting pipe is connected to the suction fan; Air outlet connection.

Abstract

The invention provides a pyrolyzing device for repairing contaminated soil. The pyrolyzing device for repairing contaminated soil comprises a soil pyrolyzing device, a transmission device, a feeding device and a discharging device, and also comprises a pyrolysis gas absorption treatment device and a gas supply device for supplying gas to the soil pyrolyzing device; the soil pyrolyzing device comprises a heating furnace body internally provided with a heating chamber; an electric heating element and a pyrolyzing barrel which brings soil in the feeding device uniformly into the discharging device are arranged in the heating furnace body; a pyrolysis gas outlet is formed in the pyrolyzing barrel; the pyrolysis gas absorption treatment device is connected to the pyrolysis gas outlet; a gas inlet and a gas outlet are formed in the heating furnace body; and the gas supply device is connected to the gas inlet. The pyrolyzing device is used for repairing soil contaminated by organic pollutantsand absorbing contaminated gas generated in the pyrolyzing process, so that the purposes of improving and repairing the contaminated soil and reducing the atmospheric contamination are achieved.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a pyrolysis device for remediating polluted soil. Background technique [0002] With the development of industrial production and the acceleration of urbanization, the soil bears more and more waste water, waste residue and waste gas from factories and human activities. If these wastes are not treated in a timely and effective manner, they will infiltrate into the soil along with the rainwater. When these pollutants accumulate to a level that exceeds the self-purification capacity of the soil, it will cause serious deterioration of the soil quality and form soil pollution. Aiming at different types of pollution in China, researchers have developed a series of remediation technologies from the three directions of physics, chemistry and biology, but the research on remediation equipment is almost blank. [0003] Among the many types of soil pollution, one of them is organ...
