Description

Technical Field

[0001] The utility model relates to the technical field of glass furnaces, and particularly to a high-temperature electrostatic precipitator device for glass furnaces. Background Technique

[0002] The flue gas of a glass furnace refers to the waste gas generated by burning fuels such as petroleum coke powder, heavy oil, and natural gas in the glass manufacturing process. These flue gases contain a large amount of pollutants, such as sulfur oxides (SOx), nitrogen oxides (NOx), and dust, which pose a serious threat to the atmospheric environment and human health. In order to achieve the goal of clean production in the glass industry, it is necessary to carry out desulfurization, denitrification, and dust removal purification treatment on these flue gases to ensure that the discharged flue gas is relatively clean. An electrostatic precipitator is a dust removal device whose working principle is to charge dust particles using a high-voltage electric field and separate the dust particles from the dust-containing gas under the action of the electric field force. This device is usually called an electrostatic precipitator or an electrical precipitator. It makes the dust particles in the gas carry charges through corona discharge, and then uses the action of the electrostatic field to separate the dust particles from the air flow. The classification of electrostatic precipitator devices mainly includes plate type and tube type, which are distinguished according to the different forms of the dust collecting electrode. The main advantages of electrostatic precipitator devices include low energy consumption, small air flow resistance, high collection efficiency for fine dust, and the ability to operate under high temperature or strongly corrosive gases.

[0003] For example, application number: CN201510316705.9, the present invention discloses a high-temperature electrostatic precipitator device for pyrolysis gas with shock waves, including a high-temperature electrostatic precipitator device housing. There is a shock wave dust collector above the high-temperature electrostatic precipitator device housing. There are a pyrolysis gas inlet and a shock wave inlet at the top of the high-temperature electrostatic precipitator device housing. The shock wave inlet is connected to the outlet of the shock wave dust collector. There is an anode plate in the high-temperature electrostatic precipitator device housing. There are several through holes on the anode plate, and a cathode rod is inserted through each through hole. One end of the cathode rod is connected together through a cathode wire. There is a pyrolysis gas outlet at the lower part of the high-temperature electrostatic precipitator device housing. The bottom of the high-temperature electrostatic precipitator device housing is an ash discharge port, and the ash discharge port is connected to an ash lock through an ash lock feed valve, and the lower part of the ash lock is connected with an ash lock discharge valve. The present invention can effectively remove the ash accumulation, scaling, and blockage of the internal components of the high-temperature electrostatic precipitator device, and ensure the clean, safe, stable, and long-term production operation of the high-temperature electrostatic precipitator device.

A filter bag box 8 is arranged at the front end of the cathode and anode box 3, and a clean gas chamber 9 is provided at the upper end of the filter bag box 8. An elevator 10 is installed at the upper end of the clean gas chamber 9, and a flue gas pipe 11 is provided at the front end of the elevator 10. A spray box 13 is provided at the bottom end of the flue gas pipe 11, and a pump body 14 is installed at the front end of the spray box 13. The spray head 18 can spray water around the device to reduce the flying dust around the device and improve the working environment. The spray pipe 19 can further settle the discharged flue gas, wet the flue gas, so that the water can contact the particles in the flue gas, increase the weight of the particles and make the particles fall downward, thereby further improving the quality of the flue gas.

[0025] As Figure 3 and Figure 4 shown, a water tank 15 is installed at the right end of the spray box 13, and a spray pipe 19 is provided at the bottom of the water tank 15. An inner cavity 20 is provided at the end of the water tank 15, and an activated carbon package 21 is arranged on the inner wall of the inner cavity 20. A connecting plate 16 is provided on the left side of the spray box 13, and a drawer 22 is provided at the end of the connecting plate 16. A diaphragm 23 is arranged inside the drawer 22. The activated carbon package 21 has a certain adsorption property and can absorb the peculiar smell inside the spray box 13, effectively preventing the emission of the peculiar smell. The diaphragm 23 is adhesively connected to the drawer 22, which is convenient for positioning the diaphragm 23. At the same time, the diaphragm 23 can collect particles and prevent the particles from directly contacting the drawer 22. Tearing the diaphragm 23 can directly handle the particles and ensure the cleanliness inside the drawer 22.

[0026] Working principle: When the high-temperature electrostatic precipitator device for glass furnaces is in use, first, according to Figure 1 - Figure 4, the flue gas generated by the glass furnace is transported through a pipeline to the flue gas inlet 2 and enters the interior of the anode-cathode box 3. After the device is powered on, an electric field is formed between the cathode and the anode inside the anode-cathode box 3. When the flue gas dust enters, ionization occurs under the action of the electric field. The charged dust moves towards the cathode and the anode respectively. Then, by using a vibrator to vibrate these two electrodes, the dust falls into the first ash hopper 5 to achieve the purpose of dust collection. The treated flue gas will enter the interior of the filter bag box 8, and the electric field is located above the interior of the filter bag box 8, which is used to generate a high-voltage electric field to charge the dust particles and adsorb them onto the surface of the filter bag under the action of the electric field. Then, the filter bags inside the filter bag box 8 are cleaned by using the back-blowing component. The dust will be discharged through the second ash hopper 12. When the first ash hopper 5 and the second ash hopper 12 discharge dust, there will be dust flying. The atomizer 18 is used for sedimentation work. The elevator 10 is used to suck the treated flue gas into the interior of the clean gas chamber 9 and then enter the interior of the spray box 13 through the flue gas pipe 11. The spray pipe 19 can further carry out sedimentation work on the discharged flue gas, wet the flue gas, so that the water can contact the particles in the flue gas, increase the weight of the particles and make the particles fall downward, thereby further improving the quality of the flue gas. The activated carbon package 21 has a certain adsorption property and can absorb the peculiar smell inside the spray box 13, effectively preventing the emission of the peculiar smell. The diaphragm 23 and the drawer 22 are adhesively connected, which is convenient for positioning the diaphragm 23. At the same time, the diaphragm 23 can collect particles and prevent the particles from directly contacting the drawer 22. Tearing the diaphragm 23 can directly handle the particles and ensure the cleanliness inside the drawer 22.
