Problems solved by technology

In areas with poor geological conditions and high soil resistivity, bentonite can generally be used as a drag-reducing agent. At present, the commercial bentonite drag-reducing agent generally needs to add some specially prepared additives (such as graphite, K 2 O), to achieve the technical index of drag reduction, thus greatly increasing the cost of drag reduction agent, and some additives are toxic and pollute the surrounding environment
In addition, the corrosion and stability of the resistance reducing agent to the grounding body have not been fully resolved. Although some resistance reducing agents have a certain resistance reducing effect in the short term after the application, the active components in the resistance reducing agent will change with time. With the loss of rainwater, it gradually loses its resistance-reducing effect, so that the grounding resistance of the grounding device rebounds rapidly

Embodiment 1

[0023] Bentonite ground to 100 mesh per 100 kg, 2×10 10 a silicate bacterium. Mix bentonite and mine tailings with about 50 kg of water. Before stirring, add silicate bacteria, about 500 grams of nutrients, 30 grams of magnesium sulfate (MgSO 4 ·7H 2 O). 50-250 kg of water can be injected after the drag-reducing agent is buried in the grounding pit. In the rainy season, the amount of water injected can be reduced and replenished by absorbing rainwater.

Embodiment 2

[0025] Every 60 kg of bentonite ground to 100 mesh, plus 40 kg of mine tailings, 1.1×10 10 a silicate bacterium. Mix bentonite and mine tailings with about 30 kg of water. Before stirring, add silicate bacteria, about 500 grams of nutrients, 30 grams of magnesium sulfate (MgSO 4 ·7H 2 O). 30-150 kg of water can be injected after the drag-reducing agent is buried in the grounding pit. During the rainy season, the amount of water injected can be reduced and replenished by absorbing rainwater.

Embodiment 3

[0027] Every 40 kg of bentonite ground to 200 mesh, plus 60 kg of mine tailings, 7×10 9 a silicate bacterium. Mix bentonite and mine tailings with about 20 kg of water. Before stirring, add silicate bacteria, about 500 grams of nutrients, 30 grams of magnesium sulfate (MgSO 4 ·7H 2 O). 20-100 kg of water can be injected after the drag-reducing agent is buried in the grounding pit. During the rainy season, the amount of water injected can be reduced and replenished by absorbing rainwater.

Abstract

The invention discloses a biological bacteria grounded resistance-reducing agent and a preparation method thereof. The biological bacteria grounded resistance-reducing agent comprises sillico aluminatemiberals and silicate bacterium. Mill tailing sand is added in another component of the biological bacteria grounded resistance-reducing agent. The preparation method of the biological bacteria grounded resistance-reducing agent comprises the steps of grinding bentonite and adding water doped with silicate bacterium and evenly stirring. The invention has the advantages of ensuring the conductivity of electrolyte in the bentonite and other functions and advantages of the invention, activating or improving conductive active components in the resistance-reducing agent and improving the resistance-reducing performance. The invention reduces the resistivity of soil around a grounded body and the contact resistance of the grounded system and protects the metal grounded body from being oxidized and corroded. The mill tailing sand is wastes of a mine. The resistance-reducing agent utilizes tailing sand, not only is environment-friendly, but also greatly reduces the self cost.

Description

technical field [0001] The invention relates to power grid grounding technology, biotechnology, aluminosilicate mineral structure technology, especially a grounding resistance reducing agent using biotechnology and its preparation method. Resistor, a technology to improve the resistance-reducing performance of grounding resistance-reducing agents. Background technique [0002] At present, in order to solve the comprehensive lightning protection of enterprise power grid, in addition to adopting the current advanced line lightning protection technology at home and abroad, it is very important to try to reduce the grounding resistance of the key points of the line. In areas with poor geological conditions and high soil resistivity, bentonite can generally be used as a drag-reducing agent. At present, the commercial bentonite drag-reducing agent generally needs to add some specially prepared additives (such as graphite, K 2 O), to achieve the technical index of drag reduction, ...
