Description

Technical Field

[0001] The utility model belongs to the technical field of electric tar collectors, and more specifically, relates to an electric tar collector system. Background Art

[0002] The electrostatic tar precipitator system consists of an oxygen analyzer, an insulated box, and other equipment. The electrostatic tar precipitator uses an electrostatic purification method, utilizing a discharge electrode and a precipitation electrode to collect tar and dust. When the system is operating, high-voltage direct current is applied between the two electrodes, generating anions and cations in the air. These charged particles interact with tar particles, causing them to adhere to the surface of the tar particles in the electrostatic field, thereby charging them. Under the influence of the electric field, the charged tar particles migrate toward the counter-electrode, ultimately settling on the electrode surface and collecting dust. The electrode plates are mounted on a circuit board. When dust and tar deposits on the electrode surface reach a certain level, an electric scraper removes them. The insulated box isolates the high-voltage electrode from the ground electrode. Its internal porcelain cylinder requires nitrogen protection to prevent gas contamination. The oxygen analyzer measures the oxygen content in the gas to prevent malfunctions in downstream user systems caused by excessive oxygen levels. The oxygen analyzer also requires nitrogen protection during operation.

[0003] In existing technology, the oxygen analyzer and the insulated box share a nitrogen pipeline and are controlled by a single master valve. The insulated box requires a nitrogen pressure of no less than 35kPa-40kPa, while the oxygen analyzer requires a nitrogen pressure of no less than 100kPa. To ensure proper operation of both, the nitrogen pressure must be controlled at 100kPa, which far exceeds the nitrogen pressure required by the insulated box, resulting in a waste of nitrogen energy.

[0028] The following describes preferred embodiments of the present invention in greater detail. Although preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0029] like Figure 1 As shown, this embodiment provides an electric tar collector system, comprising:

[0030] Electric tar collector body 1;

[0031] Nitrogen main 2;

[0032] The heat preservation box 3 is installed on the top of the electric tar precipitator body 1;

[0033] An oxygen analyzer 4 is installed on the electric tar precipitator body 1 and is used to detect the oxygen content of the coal gas discharged from the electric tar precipitator body 1;

[0034] a first pipeline 5, wherein the air inlet of the first pipeline 5 is connected to the nitrogen main pipe 2, the air outlet of the first pipeline 5 is connected to the heat preservation box 3, and the first pipeline 5 is provided with a first valve 6 for adjusting the nitrogen pressure;

[0035] The second pipeline 7 has an air inlet connected to the nitrogen main pipe 2, and an air outlet connected to the oxygen analyzer 4. The second pipeline 7 is provided with a second valve 8 for adjusting the nitrogen pressure.

[0036] Specifically, the electrostatic precipitator body 1 is based on an electrostatic purification method, utilizing a discharge electrode and a precipitation electrode to collect tar and dust. The insulation box 3 is an important component in the electrostatic precipitator, which is used to isolate the high-voltage electrode and the ground electrode. Under the action of voltage, a strong electric field is formed on the high-voltage electrode, and the tiny particles in the coal gas are charged under the action of the electric field, and are thus captured on the surface of the insulation box 3. Therefore, the temperature increase of the insulation box 3 is a prerequisite for the normal operation of the electrostatic precipitator body 1. More importantly, the internal porcelain cylinder needs to be protected by nitrogen to avoid coal gas pollution. The temperature and nitrogen protection of the insulation box 3 are very important during the operation of the electrostatic precipitator body 1. The oxygen analyzer 4 detection point is connected to the coal gas outlet 11 to detect the oxygen content in the coal gas. The first pipe 5 of this system connects the nitrogen and the insulation box 3 and is provided with a first valve 6; the second pipe 7 is connected to the nitrogen main pipe 2 and is connected to the oxygen analyzer 4 and is provided with a second valve 8; the nitrogen pressure connected to the insulation box 3 and the oxygen analyzer 4 can be controlled separately, so as to ensure that the nitrogen pressure of the insulation box 3 is controlled at the lowest level and the oxygen analyzer 4 can be displayed and operated normally, thereby avoiding waste of nitrogen energy.

[0037] Optionally, the nitrogen pressure in the first pipeline 5 is 35KPa-40KPa.

[0038] Specifically, the nitrogen pressure in the first pipeline 5 is controlled and adjusted by the first valve 6 , and the nitrogen pressure in the first pipeline 5 is 35KPa-40KPa, which can ensure the normal operation of the insulation box 3 .

[0042] Specifically, when the electric tar collector (1) is in operation, high-voltage direct current is applied between the two electrodes, generating anions and cations in the air. These charged particles act on tar particles, causing them to adsorb onto the surface of the tar particles in the electrostatic field, thereby charging the tar particles. Under the influence of the electric field, the charged tar particles migrate toward the counter-polarity electrode, ultimately settling on the electrode surface and collecting dust. The electrode plates are mounted on a circuit board. When a certain amount of dust and tar deposits on the electrode surface reach a certain level, a motorized scraper moves to remove the electrode plates.

[0043] Optionally, the oxygen analyzer 4 can control the shutdown of the electric tar precipitator body 1 according to the oxygen content in the coal gas.

[0044] In this embodiment, the oxygen analyzer 4 is shut down immediately when the detection value exceeds 2%, otherwise it will cause a failure in the gas rear user system.

[0046] Optionally, the air inlet of the first pipeline 5 is welded to the nitrogen main pipe 2, and the air outlet of the first pipeline 5 is welded to the insulation box 3;

[0048] Optionally, the thermal insulation box 3 is a three-point thermal insulation box.

[0049] Specifically, the three-point insulation box has a more stable voltage than the single-point insulation box, and the tar droplet removal rate is greatly improved.

[0050] Optionally, a gas release port 9 is provided on the top of the electric tar precipitator body 1 .

[0051] Specifically, the gas release port 9 is used for maintenance of the electric tar precipitator body 1 , and the gas in the electric tar precipitator body 1 is discharged through the gas release port 9 before maintenance.

[0052] Optionally, a gas inlet 10 is provided on the lower side wall of the electric tar precipitator body 1 , and a gas outlet 11 is provided on the upper side wall of the electric tar precipitator body 1 .

[0053] Specifically, the main function of the electric tar precipitator is to remove tar droplets in the coal gas. The coal gas enters from the coal gas inlet 10 on the lower side wall of the electric tar precipitator body 1 and is discharged from the coal gas outlet 11 on the upper side wall of the electric tar precipitator body 1 through the electrodes.

[0054] While various embodiments of the present invention have been described above, the above description is intended to be illustrative, not exhaustive, and not limited to the disclosed embodiments.
