Description

Technical Field

[0001] The utility model relates to the technical field of electric filter equipment, in particular to an electric filter used for removing carbon black dust by oxidative cracking of natural gas. Background Art

[0002] Electrostatic precipitators primarily refer to electrical devices used in industrial or commercial environments to remove or reduce suspended particulate matter in the air. These devices can be electrostatic precipitators (ESPs) or electrostatic filters, which use electric field forces to capture and remove dust and particles from the air.

[0003] The natural gas partial oxidation cracking process involves thoroughly mixing natural gas with oxygen to produce cracked gas. During this reaction, a large amount of carbon black dust is produced as a byproduct. While most of this dust is removed by carbon black water, the cracked gas still contains a high concentration of carbon black dust, making it unsuitable for further separation in downstream units. Carbon black dust is typically removed using an electrofilter. Within the electrofilter, a negatively charged discharge electrode (wire) and a settling electrode (plate) are arranged vertically between the discharge electrodes. Demineralized water is sprayed over the electrodes, capturing entrained carbon black particles. The carbon black, surrounded by the high-voltage ionized water droplets, settles on the electrodes and is removed by ionization. The demineralized water spray ensures that a continuous water film forms on the settling electrode, flushing away the carbon black. However, current electrofilters operate in a relatively open environment, making it difficult for the atomized water droplets to evenly distribute across the settling plates.

[0004] Therefore, those skilled in the art are committed to developing an electric filter for removing carbon black dust from natural gas oxidative cracking, reducing the escape of cracked gas and facilitating the washing of carbon black with softened water. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide an electric filter for removing carbon black dust by oxidative cracking of natural gas, thereby reducing the escape of cracked gas and facilitating the washing of carbon black with softened water.

[0006] The technical solution of the utility model to solve the above technical problems is as follows:

[0007] An electric filter for removing carbon black dust by oxidative cracking of natural gas, comprising

[0008] Box;

[0009] A dust removal chamber is installed in the box body, and the dust removal chamber is connected to an air inlet and an air outlet, the air inlet and the air outlet are respectively located on the lower side and the upper side of the box body, and the lower side of the dust removal chamber is also connected to a liquid storage bin;

[0010] An electric filter dust removal component is installed in the dust removal cavity, and an adjustment component is connected to the end of the electric filter dust removal component;

[0011] A spray assembly is installed in the dust removal chamber and is located on the upper side of the electric filter dust removal assembly.

[0012] The beneficial effects of the above scheme are as follows: the mixture of cracked gas and carbon black enters the dust removal chamber from the air inlet, the strong electric field generated by the electric filter dust removal component causes the carbon black to settle on the electrode plate, and the softened water sprayed by the spray component sprays the carbon black settled on the electrode plate and flows into the liquid storage tank;

[0013] The dust removal chamber adopts a closed cavity and is only connected to the air inlet and outlet to reduce gas escape and improve the dust removal efficiency of the cracking gas;

[0014] The spray assembly sprays in multiple directions to remove the carbon black deposited on the electrode plate and reduce residue.

[0015] On the basis of the above technical solution, the present invention can also be improved as follows.

[0016] Furthermore, the spray assembly includes a spray pipe, a liquid inlet pipe and an atomizing rotary nozzle. The spray pipe is installed in the dust removal chamber. The liquid inlet pipe is connected to the spray pipe and extends out of the box body. The spray pipe is equipped with multiple atomizing rotary nozzles arranged at intervals.

[0017] The beneficial effect of adopting the above further solution is that the softened water enters the spray pipe through the liquid inlet pipe and is then sprayed out through the atomizing rotary nozzle, thereby reducing the carbon black residue on the electrode plate.

[0018] Furthermore, the atomizing rotary nozzle includes a rotary nozzle body and a first spray port located at the bottom of the rotary nozzle body. The rotary nozzle body has multiple side surfaces, and each side surface is respectively provided with a second spray port.

[0019] The beneficial effect of adopting the above further scheme is that the atomizing rotary nozzle has multiple spray ports facing different directions. At the same time, during the spraying process, the rotary head body rotates under the action of hydraulic pressure, so that all positions in the dust removal chamber can be flushed by softened water, and then all positions of the electrode plate are flushed clean.

[0020] Furthermore, the electrostatic precipitator assembly includes an anode busbar, an anode plate, an insulating plate, a cathode filament and a cathode busbar. The anode busbar and the insulating plate are arranged opposite to each other, and a plurality of anode plates are installed between the anode busbar and the insulating plate at intervals. A plurality of cathode filaments are installed between the anode busbar and the insulating plate. The cathode filaments in the same vertical column are spaced apart from the anode plate, and the cathode filaments extend out of the insulating plate and are connected to the cathode busbar.

[0021] The beneficial effect of adopting the above further scheme is: the anode plate busbar provides positive charge to each anode plate, and the cathode plate busbar provides negative charge to each cathode filament, and a strong electric field is generated between the anode plate and the cathode filament, so that the carbon black is deposited on the electrode plate.

[0022] Furthermore, insulators are installed between the cathode wire and the insulating plate, and between the cathode wire and the anode busbar.

[0023] The beneficial effect of adopting the above further solution is that the insulator prevents interference between the positive electrode and the negative electrode.

[0024] Furthermore, the anode busbar and the cathode busbar are connected to an anode terminal and a cathode terminal, respectively, and the anode terminal and the cathode terminal both extend out of the box.

[0025] The beneficial effect of adopting the above further solution is that the anode terminal and the cathode terminal are used to connect to the positive electrode and the negative electrode respectively.

[0026] Furthermore, the adjustment assembly includes an adjustment rod and a hinged rod, one end of the adjustment rod is connected to the cathode busbar and extends out of the dust removal chamber, the end of the adjustment rod and the side opposite to the cathode busbar are hinged to the middle of the hinged rod, one end of the hinged rod is connected to the side wall of the box, and the other end of the hinged rod is connected to a tension spring and an elastic force adjuster in sequence, and the other end of the elastic force adjuster is connected to the inner wall of the box.

[0027] The beneficial effect of adopting the above further solution is that the tension spring pulls the hinged rod to rotate around the adjustment rod, thereby tensioning the cathode filament.

[0028] Furthermore, an observation window and a control device are installed on the outer wall of the box.

[0029] The beneficial effect of adopting the above further solution is that the observation window helps the operator to observe the dust removal situation in the box in time, so as to make corresponding adjustments in time. BRIEF DESCRIPTION OF THE DRAWINGS
