Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ash hopper manhole doors, in particular to an ash hopper manhole door structure which is easy to install. Background Art
[0002] The high-dust, high-temperature, high-concentration SO2 flue gas generated during the smelting process of copper concentrate in the smelting furnace is dedusted by an electrostatic precipitator and then transported to the acid-making process through a fan to produce concentrated sulfuric acid. The electrostatic precipitator is a process in which the dust is charged under the condition of an electric field. The dust moves under the action of the electric field force and is deposited on the electrodes in the electric field. When the dust is deposited to a certain thickness, the dust falls into the ash hopper under the action of the vibrator. A scraper conveyor is set at the bottom of the ash hopper to collect and pack the collected dust.
[0003] Workers usually need to check the inside of the ash hopper through the manhole door. The existing manhole door is not sealed tightly, which can easily allow air to enter. The fly ash produced by copper smelting mainly contains PbSO4, ZnSO4·H2O, etc. ZnSO4·H2O (zinc sulfate monohydrate) is very easy to deliquesce in the air, forming acidic corrosive substances that corrode the manhole door, causing fly ash leakage and polluting the environment. At the same time, the manhole door currently used is generally connected to the ash hopper with bolts, which is difficult to install and disassemble, and the workload is large, which affects production efficiency. In addition, the manhole door is heavy and high from the ground, requiring the cooperation of multiple people, there is a risk of falling, and there are great safety hazards. Utility Model Content
