[0002] The electric tar collector is a machine used for gas mist purification, specifically refers to a coke oven gas primary cooling equipment that uses the action of a high-voltage direct current electric field to separate tar droplets and coal gas.

[0003] The internal shapes of the electric tar precipitator can be roughly divided into three types: concentric circle type, tubular type and honeycomb type. In these three structures, high voltage direct current is applied between the metal wire and the metal tube wall (or electrode plate) to maintain an electric field sufficient to ionize the gas, forming a corona zone between the anode and cathode, and then purifying the mist.

[0004] It has been found in long-term observation and use of existing electric tar precipitators that when the temperature of the electric tar precipitator is too low, tar, naphthalene and water vapor in the coal gas condense and deposit on the insulator. When too many impurities are deposited, the electric tar precipitator will be affected.

Through the above structure, the middle of the electric tar collector body can be continuously heated, so that the heat is conducted to the inside of the electric tar collector body to achieve heating of the inside of the electric tar collector body. At the same time, by heating the inside of the electric tar collector body, the condensation and deposition of tar, naphthalene and water vapor in the coal gas on the insulator can be reduced, thereby affecting the operation of the electric tar collector body.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figures 1 to 4As shown, an electric tar collector heating device described in an embodiment of the utility model comprises an electric tar collector body 1; a protective shell 12 is provided on the outside of the electric tar collector body 1; a thermal insulation cushion layer 13 is fixedly connected to the inner ring of the protective shell 12; a heating wire 14 is fixedly connected to the side wall of the electric tar collector body 1; the heating wire 14 is located near the middle of the electric tar collector body 1 and is located inside the protective shell 12; the heating wire 14 is located inside the protective shell 12; a plurality of copper wires 15 pass through the middle of the heating wire 14; the plurality of copper wires 15 are in contact with the side wall of the electric tar collector body 1. When working, in order to prevent tar, naphthalene and water vapor in the coal gas from condensing and depositing on the insulator, it is necessary to heat the electric tar collector. At this time, the heating wire 14 is started. As the heating wire 14 is started, the surface of the heating wire 14 will gradually heat up. The temperature emitted by the hot wire 14 will fill the interior of the protective shell 12. At the same time, the multiple copper wires 15 inserted in the middle of the heating wire 14 will conduct the heat emitted by the heating wire 14. At this time, because the copper wire 15 and the electric tar precipitator body 1 are in close contact, the multiple copper wires 15 will synchronously heat the side walls of the electric tar precipitator body 1. At the same time, the emitted heat will be blocked by the thermal insulation cushion layer 13, so that it will be continuously preserved in the interior of the protective shell 12. Through the above structure, the middle part of the electric tar precipitator body 1 can be continuously heated, so that the heat can be conducted to the interior of the electric tar precipitator body 1 to achieve heating of the interior of the electric tar precipitator body 1. At the same time, by heating the interior of the electric tar precipitator body 1, the condensation and deposition of tar, naphthalene and water vapor in the coal gas on the insulator can be reduced, thereby affecting the operation of the electric tar precipitator body 1.

[0024] like Figure 3As shown, the inner ring of the protective shell 12 is provided with two slide grooves 2; the two slide grooves 2 are located near the two ends of the protective shell 12; the slide grooves 2 are slidably connected inside with a sliding ring 21; the inner ring of the protective shell 12 is fixedly connected with two fixing plates 22; the two fixing plates 22 are both located on the side of the sliding ring 21; the top of the sliding ring 21 is provided with a plurality of second through holes 24; the plurality of second through holes 24 are equidistantly distributed; the top of the fixing plate 22 is provided with a plurality of first through holes 23; the plurality of first through holes 23 are equidistantly distributed, and the radius of the first through holes 23 and the second through holes 24 are the same. When working, the two ends of the protective shell 12 can be closed by cooperating with the fixing plate 22 and the sliding ring 21. At this time, when the internal temperature of the protective shell 12 is too high, the sliding ring 21 can be rotated to As the sliding ring 21 rotates, the second through hole 24 and the first through hole 23 gradually overlap. When the second through hole 24 and the first through hole 23 overlap, a hole will be generated. At this time, as the hole is generated, the heat inside the protective shell 12 will gradually evaporate through the flow of air, so that the internal temperature of the protective shell 12 will gradually decrease. When reheating is required, the sliding ring 21 can be rotated again. At this time, as the sliding ring 21 rotates again, the second through hole 24 and the first through hole 23 can be gradually separated, so that the hole is eliminated. At this time, as the heating wire 14 is started, the temperature inside the protective shell 12 will gradually increase. Through the above structure, the sliding ring 21 can be rotated to overlap and separate the second through hole 24 and the first through hole 23, so as to achieve the dissipation and maintenance of the temperature inside the protective shell 12.

[0025] like Figure 1 and Figure 4 As shown, two slots 3 are provided in the middle of the electrostatic precipitator body 1; the two slots 3 are both located on the side close to the sliding ring 21; an annular block 31 is detachably installed inside the slot 3; a plurality of brushes 32 are provided in the middle of the annular block 31; the plurality of brushes 32 are equidistantly distributed and in contact with the top of the sliding ring 21. When working, the annular block 31 is installed inside the slot 3. At this time, as the annular block 31 is installed, a plurality of brushes 32 will also be installed to the specified position. At this time, as the brushes 32 are installed, the brushes 32 will contact with the top of the sliding ring 21. At this time, by rotating the sliding ring 21, the brushes 32 will continuously clean the top of the sliding ring 21. Through the above structure, it is possible to reduce the accumulation of excessive dust or impurities on the top of the sliding ring 21, thereby reducing the sliding ring 21 from sliding or blocking the second through hole 24.

[0026] like Figure 2As shown, a plurality of fixing rings 4 are fixedly connected to the middle of the electric tar precipitator body 1; the plurality of fixing rings 4 are equidistantly distributed, and the heating wire 14 is located inside the fixing rings 4; the fixing rings 4 do not contact the heating wire 14, and during operation, as the heating wire 14 is started, the interior of the protective shell 12 is heated, thereby heating the interior of the electric tar precipitator body 1. At this time, by providing a plurality of fixing rings 4, the plurality of fixing rings 4 are used to fix and limit the heating wire 14, thereby reducing the heating wire 14 from falling off the side wall of the electric tar precipitator body 1 over time.

[0027] like Figure 4 As shown, the side walls of the two sliding rings 21 are fixedly connected with a plurality of gripping rods 5; the plurality of gripping rods 5 are equidistantly distributed and staggered with the second through hole 24. When working, by rotating the sliding ring 21, the first through hole 23 and the second through hole 24 can be overlapped and separated, thereby realizing the control of the internal temperature of the protective shell 12. At this time, by setting the gripping rod 5, the sliding ring 21 can be driven to slide inside the slide groove 2 by pulling the gripping rod 5. Through the above structure, the situation that the sliding ring 21 is difficult to move due to the excessively high internal temperature of the protective shell 12 can be reduced. At the same time, by setting the gripping rod 5, the sliding ring 21 can be more conveniently slid.

[0028] like Figure 4 As shown, a protrusion 6 is fixed to the top of the grip 5; an anti-skid pad 61 is pasted to the middle of the protrusion 6. When working, the grip 5 can be rotated to drive the sliding ring 21 to slide. At this time, the friction of the grip 5 on the hand can be increased by setting the protrusion 6. Through the above structure, the friction between the hand and the grip 5 can be increased, thereby reducing the situation where the hand falls off from the middle of the grip 5.

[0029] like Figure 4 As shown, the fixing plate 22 and the sliding ring 21 fit tightly together. Through the above arrangement, the heat inside the protective shell 12 can be reduced from flowing out from the gap between the fixing plate 22 and the sliding ring 21.

[0030] During operation, in order to prevent tar, naphthalene and water vapor in the coal gas from condensing and depositing on the insulator, the electric tar precipitator needs to be heated. At this time, the heating wire 14 is started. As the heating wire 14 is started, the surface of the heating wire 14 will gradually heat up. At this time, the temperature emitted by the heating wire 14 will fill the inside of the protective shell 12. At the same time, the multiple copper wires 15 inserted in the middle of the heating wire 14 will conduct the heat emitted by the heating wire 14. At this time, because the copper wire 15 is in close contact with the center of the electric tar precipitator body 1, the multiple copper wires 15 will synchronously heat the side wall of the electric tar precipitator body 1. At the same time, the heat emitted will be kept warm. The cushion layer 13 blocks the heat, thereby continuously storing it inside the protective shell 12. The fixing plate 22 and the sliding ring 21 cooperate to close the two ends of the protective shell 12. At this time, when the internal temperature of the protective shell 12 is too high, the sliding ring 21 can be rotated. As the sliding ring 21 rotates, the second through hole 24 and the first through hole 23 gradually overlap. When the second through hole 24 and the first through hole 23 overlap, a hole will be generated. At this time, as the hole is generated, the heat inside the protective shell 12 will gradually evaporate through the flow of air, thereby gradually reducing the internal temperature of the protective shell 12. When reheating is required, the sliding ring 21 can be rotated again. The ring 21 rotates. At this time, as the sliding ring 21 rotates again, the second through hole 24 and the first through hole 23 can be gradually separated, so that the hole is eliminated. At this time, as the heating wire 14 is started, the temperature inside the protective shell 12 will gradually increase, and the annular block 31 is installed inside the card slot 3. At this time, as the annular block 31 is installed, multiple brushes 32 will also be installed to the specified position. At this time, as the brush 32 is installed, the brush 32 will contact the top of the sliding ring 21. At this time, by rotating the sliding ring 21, the brush 32 will continuously clean the top of the sliding ring 21. As the heating wire 14 is started, The interior of the protective shell 12 will be heated, thereby realizing heating of the interior of the electric tar precipitator body 1. At this time, multiple fixing rings 4 are provided to fix and limit the heating wire 14. By rotating the sliding ring 21, the first through hole 23 and the second through hole 24 can be overlapped and separated, thereby realizing the control of the internal temperature of the protective shell 12. At this time, a grip rod 5 is provided, and the sliding ring 21 can be driven to slide inside the slide groove 2 by pulling the grip rod 5. The sliding ring 21 can be driven to slide by rotating the grip rod 5. At this time, the friction of the grip rod 5 on the hand can be increased by providing a protrusion 6.
