Description
Technical Field
[0001] The utility model belongs to the technical field of industrial fume purification, and specifically relates to an electric tar precipitator. Background Technique
[0002] An electric tar precipitator refers to a primary cooling equipment for coke oven gas that uses the action of a high-voltage DC electric field to separate tar droplets and gas. Its working principle is to apply a high-voltage direct current between a metal wire and a metal pipe wall to maintain an electric field sufficient to ionize the gas, so as to form a corona region between the anode and the cathode. According to the electric field theory, positive ions are adsorbed on the negatively charged corona electrode, and negative ions are adsorbed on the positively charged precipitation electrode; all the ionized positive and negative ions fill the entire space between the corona electrode and the precipitation electrode. When the gas containing impurities such as tar droplets passes through this electric field, the impurities adsorbed with negative ions and electrons move to the precipitation electrode under the action of the electric field Coulomb force, release the charges carried, and are adsorbed on the precipitation electrode, thus achieving the purpose of purifying the gas, which is usually called the charge phenomenon. However, when the existing electric tar precipitator is in use, if the precipitation electrode and the corona electrode of one of the pipes lose power, gas will pass through the upper end of the precipitation electrode. Due to the loss of power, the tar removal effect will not meet the requirements, which affects the exhaust effect. Therefore, we propose an electric tar precipitator. Content of the Utility Model
[0003] The utility model provides an electric tar precipitator to solve the technical problems raised in the above background technique.
[0004] To achieve the above object, the technical solutions adopted by the utility model are as follows:
[0005] An electric tar precipitator, the key lies in that it includes a plurality of tubular precipitation electrodes fixedly arranged inside the shell, and the precipitation electrodes are equidistantly distributed. An electric corona wire coaxially passes through the inside of the precipitation electrode. The upper and lower ends of the electric corona wire are fixedly connected to a hanger, and the hanger is fixedly connected to the shell. A porcelain tube is coaxially arranged above the precipitation electrode, and the electric corona wire coaxially passes through the inside of the porcelain tube. A plug and an iron plate for blocking the upper port of the precipitation electrode are coaxially movably sleeved outside the porcelain tube. The iron plate is fixedly connected to the top surface of the plug. An electromagnet is coaxially arranged above the plug. The upper end of the porcelain tube passes through the electromagnet and is fixedly connected to it. The two sides of the bottom end of the electromagnet are elastically connected to the plug through elastic components. The electromagnet, the precipitation electrode, the electric corona electrode are connected in series with an external high-voltage power supply.
[0006] Further, the upper end of the precipitation electrode passes through the upper partition plate and is fixedly connected to it, and the lower end of the precipitation electrode passes through the lower partition plate and is fixedly connected to it. The upper partition plate and the lower partition plate are respectively fixedly connected to the inner wall of the shell.
[0007] Further, a fixing ring is arranged above the electromagnet. The fixing ring is coaxially and fixedly sleeved outside the porcelain tube. Connecting rods are respectively and fixedly connected to both sides of the fixing ring. The connecting rods are fixedly connected to the upper end surface of the upper partition plate.
[0008] Further, the elastic component includes a stable sliding rod fixedly connected to the bottom end of the electromagnet. The stable sliding rod slides downward through the iron plate and is slidably inserted into the plug. A spring is coaxially sleeved outside the stable sliding rod. The top end of the spring is fixedly connected to the bottom end of the electromagnet, and the bottom end of the spring is fixedly connected to the iron plate.
[0009] Further, a limiting ring is coaxially and slidably sleeved outside the bottom end of the plug. Connecting rods are respectively and fixedly connected to both sides of the bottom end of the limiting ring. The bottom ends of the connecting rods are fixedly connected to the precipitation electrode.
[0010] Further, electric conduction insulator boxes are fixedly connected to the openings at the left and right sides of the top end of the housing. An exhaust pipe and an air inlet pipe are respectively and fixedly connected to the upper and lower ends of the side wall of the housing. A liquid discharge pipe is fixedly connected to the bottom end of the side wall of the housing.
[0011] Due to the adoption of the above structure, compared with the prior art, the technical progress achieved by the present utility model is as follows: When a certain precipitation electrode and the corona wire are powered off, the electromagnet will lose magnetism, and the iron plate will not be attracted by the electromagnet, so it cannot overcome the elastic force of the elastic component. The elastic component pushes against the iron plate and the plug to slide downward and displace outside the porcelain tube, so that the plug seals the upper end of the precipitation electrode. In this way, the gas will not be introduced into the precipitation electrode and the corona wire that have lost the ionization function, thus not affecting the filtering effect of the electric tar precipitator. The powered-off precipitation electrode is sealed by the plug and will not filter the gas, enabling other normal precipitation electrodes and corona wires to still be used normally without affecting the filtering effect.

Detailed implementation manners
[0019] The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustration and explanation of the present utility model, and are not intended to limit the present utility model.
[0020] The present utility model discloses an electrostatic tar precipitator, as Figures 1-4As shown in the figure, it includes several tubular precipitator electrodes 8 fixedly arranged inside the housing 1. Each precipitator electrode 8 is equidistantly distributed. A corona wire 9 coaxially passes through the inside of the precipitator electrode 8. The upper and lower ends of the corona wire 9 are respectively fixedly connected to a hanger 18, and the hanger 18 is fixedly connected to the housing 1. A porcelain tube 10 is coaxially arranged above the precipitator electrode 8. The corona wire 9 coaxially passes through the inside of the porcelain tube 10. A plug 13 and an iron plate 14 are coaxially and movably sleeved outside the porcelain tube 10. The plug 13 is used to block the upper port of the precipitator electrode 8. The iron plate 14 is fixedly connected to the top surface of the plug 13. An electromagnet 17 is coaxially arranged above the plug 13. The upper end of the porcelain tube 10 passes through the electromagnet 17 and is fixedly connected to the electromagnet 17. The two sides of the bottom end of the electromagnet 17 are elastically connected to the plug 13 through elastic components. The electromagnet 17, the precipitator electrode 8, and the corona wire 9 are connected in series with an external high-voltage power supply. The left and right sides of the top end of the housing 1 are fixedly connected with lead-in insulator boxes 2. The lead-in insulator boxes 2 are connected to high-voltage wires. The precipitator electrode 8 and the corona wire 9 are respectively powered by an external high-voltage power supply. And the positive and negative poles of the electromagnet 17 are also connected to the terminals of the positive and negative poles of the corresponding precipitator electrode 8 and corona wire 9. When the electromagnet 17 is powered, a transformer needs to be connected to change the magnitude of the supply voltage. The upper and lower ends of the side wall of the housing are respectively fixedly connected with an exhaust pipe and an intake pipe. The bottom end of the side wall of the housing is fixedly connected with a drain pipe. The housing 1, the lead-in insulator boxes 2, the exhaust pipe 3, the intake pipe 4, and the drain pipe 5 all adopt existing equipment. The working principle and advantages of the present utility model are as follows: When a certain precipitator electrode 8 and corona wire 9 are powered off, the electromagnet 17 will demagnetize, and the iron plate 14 will not be attracted by the electromagnet 17, so it cannot overcome the elastic force of the elastic component. The elastic component pushes against the iron plate 14 and the plug 13 to slide downward outside the porcelain tube 10, so that the plug 13 blocks the upper end of the precipitator electrode 8. In this way, the precipitator electrode 8 and corona wire 9 that have lost the ionization function will not pass gas, thus not affecting the filtering effect of the electro-tar precipitator, and enabling other normal precipitator electrodes 8 and corona wires 9 to still be used normally.
[0021] Specifically, the upper end of the precipitator electrode 8 passes through the upper partition plate 6 and is fixedly connected to the upper partition plate 6. The lower end of the precipitator electrode 8 passes through the lower partition plate 7 and is fixedly connected to the lower partition plate 7. The upper partition plate 6 and the lower partition plate 7 are respectively fixedly connected to the inner wall of the housing 1. To fix the porcelain tube 10, a fixing ring 19 is arranged above the electromagnet 17. The fixing ring 19 is coaxially and fixedly sleeved outside the porcelain tube 10. Two connecting rods 20 are respectively fixedly connected to the two sides of the fixing ring 10. The connecting rods 20 are fixedly connected to the upper end surface of the upper partition plate 6.
[0022] The elastic component of the utility model comprises a stable sliding rod 15 fixedly connected to the bottom end of an electromagnet 17. The stable sliding rod 15 slides downward through an iron plate 14 and is slidably inserted into a plug 13. A spring 16 is coaxially sleeved outside the stable sliding rod 15. The top end of the spring 16 is fixedly connected to the bottom end of the electromagnet 17, and the bottom end of the spring 16 is fixedly connected to the iron plate 14. By arranging the spring 16, when the precipitation electrode 8 and the corona wire 9 are not de-energized, the electromagnet 17 overcomes the elastic force of the spring 16 to attract the iron plate 14 to drive the plug 13 to move upward, so that the upper port of the precipitation electrode 8 is opened. When a certain precipitation electrode 8 and corona wire 9 are powered off, the electromagnet 17 will lose magnetism, and the iron plate 14 will not be attracted by the electromagnet 17, so it cannot overcome the elastic force of the spring 16. The spring 16 abuts against the iron plate 14 and the plug 13 to slide downward and displace outside the porcelain tube 10, so that the plug 13 seals the upper end of the precipitation electrode 8. The porcelain tube 10 can play an insulating role and a smooth role, so that the up and down displacement of the plug 13 is more stable, and the effect of the stable sliding rod 15 is also to make the up and down displacement of the plug 13 stable.
[0023] Specifically, a limiting ring 12 is coaxially and slidably sleeved outside the bottom end of the plug 13. Connecting rods 11 are respectively fixedly connected to both sides of the bottom end of the limiting ring 12. The bottom ends of the connecting rods 11 are fixedly connected to the upper end of the precipitation electrode 8. By arranging the limiting ring 12 and the connecting rods 11, the plug 13 moves up and down in the limiting ring 12 without deviation, further enhancing the stability of the displacement of the plug 13.
[0024] Finally, it should be noted that the above are only the preferred embodiments of the utility model and are not used to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included within the scope of protection of the claims of the utility model.
