Embodiment 1

[0030] Such as figure 1 As shown, this embodiment provides an open anode bed without filler, including a screen 100, a wellbore 200 arranged on the upper part of the screen 100 along the axial direction of the screen 100, and an anode arranged in the screen 100 300, specifically:

[0031] The screen 100 and the wellbore 200 are injected with brine.

[0032] The open unfilled deep-well anode bed includes a screen 100, a wellbore 200 and an anode 300. The wellbore 200 is arranged on the upper part of the screen 100, and the wellbore 200 is arranged along the axis of the screen 100 and connected to the screen 100. The anode 300 Set inside the screen pipe 100, the screen pipe 100 and the wellbore 200 are filled with brine. Compared with the prior art, the position where the anode 300 is placed is filled with granular coke, and the part above the anode 300 is filled with Stone or sand, use coke to increase the contact surface of the anode 300, maintain humidity to reduce the resi...

Embodiment 2

[0045] This embodiment provides a cathodic protection system, which includes the open and unfilled deep-well anode bed in Embodiment 1. The cathodic protection system can also include a power supply device and a conductor, etc. The protection current is introduced from the power supply device into the conductor in the soil, and the protection current is sent into the soil through the open and unfilled deep well anode bed, and flows into the protected pipeline through the soil , so that the surface of the pipeline is cathodically polarized, and the current flows from the pipeline into the negative electrode of the power supply device, thereby forming an electrolytic cell. By injecting brine into the screen pipe 100 and the wellbore 200, the anode 300 is filled with brine, and the wellbore 200 is used for direct Exhaust effectively reduces the resistance and avoids the occurrence of gas resistance, making the protection effect better. At the same time, it avoids the scrapping of ...

Abstract

The invention provides an open packless deep-well anode ground bed and a cathode protection system and relates to the technical field of electrochemical equipment. The open packless deep-well anode ground bed comprises a screen pipe, a shaft arranged above the screen pipe along the axis of the screen pipe, and an anode arranged in the screen pipe; the screen pipe and the shaft are filled with saline water; the technical problem of the prior art that a deep-well anode ground bed easily experiences air resistance, resulting in poor protection and low scrapping rate, is solved; by injecting saline water into the screen pipe and the shaft and exhausting straightly via an opening of the shaft, resistance is reduced effectively, air resistance is avoided, the protection effect is improved, the scrapping problem of the anode bed due to air resistance is avoided, scrapping rate is decreased, the service life is extended, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of electrochemical equipment, in particular to an open-open, filler-free deep well type anode bed and a cathodic protection system. Background technique [0002] The anode ground bed is a facility for installing and placing anodes in the applied electric cathodic protection system, also known as auxiliary anode. In the impressed current cathodic protection system, the protection current is introduced from the power source into the conductor in the soil, and the protection current is sent to Into the soil, through the soil into the protected pipeline, so that the surface of the pipeline is cathodically polarized (to prevent electrochemical corrosion), and the current flows from the pipeline to the negative electrode of the power supply to form a loop. This loop forms an electrolytic cell, and the pipeline is in the loop. The negative electrode is in a reducing environment to prevent corrosion, while the anode...
