Embodiment 1

[0046] A method for collecting and recycling transformer insulating waste oil, said method comprising

[0047] 1. Establish a transformer oil recycling center to recycle waste oil;

[0048] 2. Carry out oil level monitoring and GPRS positioning for new oil barrels and waste oil barrels in substations:

[0049] The liquid level sensor monitors the oil level, and the oil level data is transmitted to the data processing module through the wireless data acquisition module, and the data processing module transmits the data to the background server through the 4G communication module;

[0050] Install GPRS positioning module on new oil drums and waste oil drums in substations;

[0051] After installing the APP application on the mobile terminal, you can browse the current liquid level schematic diagram, historical value, and location of the new oil barrels and waste oil barrels in each substation according to the authority, and you can customize the upper and lower limit alarm valu...

Embodiment 2

[0063] Oil level monitoring and GPRS positioning of new and waste oil barrels in 77 substations:

[0064] The liquid level sensor monitors the oil level, and the oil level data is transmitted to the data processing module through the wireless data acquisition module, and the data processing module transmits the data to the background server through the 4G communication module;

[0065] Install GPRS positioning module on new oil drums and waste oil drums in substations;

[0066] After installing the APP application on the mobile terminal, you can browse the current liquid level schematic diagram, historical value, and location of the new oil barrels and waste oil barrels in each substation according to the authority, and you can customize the upper and lower limit alarm values ​​of the liquid level;

[0067] After the oil level monitored by the liquid level sensor reaches the alarm value, click the alarm station to generate a navigation path, and give voice prompts during the j...

Embodiment 3

[0114]Adsorbent is provided in the adsorption tank group 4 described in embodiment 1, and described adsorbent comprises the following components by weight: mass percent concentration is 25 parts of hydrochloric acid solution of 17%, and mass percent concentration is 9% sodium sulfate 24 parts of the solution, 25 parts of sodium silicate solution with a mass percent concentration of 8%, and 1.32 parts of ammonia water with a concentration of 19%. The above solutions are mixed, then aged, baked and dried to make the finished adsorbent. The aging temperature is 85° C., and the aging time is 7 hours. The drying temperature is 110°C for 4 hours, soaked in phosphoric acid, washed with water, and then baked at 135°C for 23 hours to obtain the finished adsorbent. The average pore size of the finished adsorbent reaches 10-50nm. The specific surface of the adsorbent is 300-500m 2 / g.

Abstract

The invention relates to a waste transformer insulating oil collection and recycling method, and mainly aims to recycle and circulate waste transformer oil. The waste transformer insulating oil collection and recycling method comprises the following steps: establishing a transformer oil recycling treatment center for recycling and reusing waste oil; performing oil level monitoring and GPRS (General Packet Radio Service) positioning on a new oil drum and a waste oil drum of a transformer substation; monitoring an oil level by using an oil level sensor, transmitting oil level data to a data processing module by a wireless data acquisition module, and transmitting data to a background server by the data processing module through a 4G communication module; mounting GPRS positioning modules on the new oil drum and the waste oil drum of the transformer substation; after the oil level monitored by the oil level sensor reaches an alarm value, clicking an alarm station to generate a navigation route, performing voice prompting in the moving process, and transporting waste oil of a corresponding transformer substation back to the transformer oil recycling treatment center, thereby recycling the waste oil. Due to adoption of the waste transformer insulating oil collection and recycling method provided by the invention, no secondary pollution can be caused, recycled inferior oil is free of pollution source, and thus the transformer oil can be recycled and reused.

Description

technical field [0001] The invention relates to a method for collecting and recycling transformer insulating waste oil, which is mainly used for recycling and recycling transformer waste oil. Background technique [0002] The State Environmental Protection Administration’s reply letter on whether “waste oil” is “solid waste” (Huanfahan (2002) No. 3) pointed out that “waste oil” is a “solid waste” and should be disposed of as solid waste. The "Environmental Protection Law of the People's Republic of China" (implemented on January 1, 2015) stipulates the prevention and control of pollution and other public hazards and its legal responsibilities, and the reduction of pollutant emissions, which is encouraged and supported by the government. Pollution is caused, the substation is shut down, and punishments are imposed for several days. In serious cases, the responsible person shall be held legally responsible. "State Grid Corporation Environmental Protection Technology Supervisi...
