Embodiment 1

[0031] The embodiment is basically as attached figure 1 Shown: a sophorolipid compound spraying device for soil improvement includes a storage layer 1, a rotating layer 2 and a base 3 sequentially connected from top to bottom, and the connection between the storage layer 1 and the rotating layer 2 has several The helical teeth 4 , one end of the helical teeth 4 is fixedly connected to the rotating layer 2 , and the other end of the helical teeth 4 extends to the storage layer 1 .

[0032] Please refer to figure 2 ,and image 3 There is a rotating notch 5 at the overlap between the helical teeth 4 and the storage layer 1, and an outflow channel 6 is provided above the adjacent helical teeth 4, and the outflow channel 6 is connected to the storage layer 1, and a flow channel 6 is provided below the adjacent helical teeth 4. Channel 7, the flow channel 7 is located in the rotating layer 2, the flow channel 7 is provided with a feed port and a discharge port 8 along the flow di...

Embodiment 2

[0042] The difference between this technical solution and the above-mentioned embodiment is that a sophorolipid compound for improving soil is disclosed in this embodiment, which includes the following components: sophorolipid, NaCl, ethylenediaminetetraacetic acid, diethyl hexanoate , konjac glucomannan and water, wherein the ratio of sophorolipids, NaCl, ethylenediaminetetraacetic acid, diethyl hexanoate, konjac glucomannan and water is 4:1:2:2:2:6.

[0043] (1) Screen out the better oily soil cleaning process: through single factor experiments, the solution for cleaning oily soil is determined under this formula: the liquid-solid ratio is 2:1, the temperature is 35°C, the stirring rate is 600r / min, The cleaning time is 20 minutes, and the soil crude oil removal rate can reach up to 92.31% under this condition.

[0044] (2) Scale-up experiments and repeated use experiments show that the oil-bearing soil is enlarged to 300 times, and the sophorolipid compound can still mainta...

Abstract

The invention discloses a sophorolipid compound for improving soil and a spraying device, and belongs to the field of soil remediation. The invention relates to a sophorolipid compound for improving soil. The sophorolipid compound is prepared from the following components: sophorolipid, NaCl, ethylenediamine tetraacetic acid, diethyl aminoethyl hexanoate, konjac glucomannan and water. The spraying device for improving the soil comprises a storage layer, a rotating layer and a base which are sequentially connected from top to bottom, a plurality of helical teeth are arranged at the joint of the storage layer and the rotating layer, outflow channels are arranged above the adjacent helical teeth, and the outflow channels are communicated with the storage layer. According to the technical scheme, due to the special sprayed substance, the sprayed substance is a sophorolipid compound with certain viscosity. Therefore, in the technical scheme, the sophorolipid compound flowing from the storage layer to the outflow channel is cut through the helical teeth, so that the agglomerated viscous compound is prevented from blocking the channel, the volume of the compound is reduced, the single-flow sophorolipid compound can be sprayed out conveniently, and the spraying speed and distance of the sophorolipid compound can be kept conveniently.

Description

technical field [0001] The invention belongs to the field of soil restoration, in particular to a sophorolipid compound and a spraying device for improving soil. Background technique [0002] With the rapid development of the petroleum industry, in the process of crude oil exploration, transportation, processing and storage, a large amount of petroleum-contaminated soil will inevitably be produced, and the oil will penetrate into the groundwater layer and affect the growth of plants and crops. [0003] Active agents for remediating soil toxicity are mainly divided into biological surfactants and non-biological surfactants. Non-biological surfactants are commonly used sodium dodecylbenzenesulfonate, sodium dodecyl sulfate, etc., which have certain toxicity to plant growth and are not conducive to the further treatment of recycled soil. Compared with biological surfactants , has the characteristics of low toxicity and biodegradability. Sophorolipid is one of the typical biol...
