Method for movably collecting, conveying, dedusting and desulfurizing dust of coke oven coke guide

Abstract

A method for movably collecting, conveying, dedusting and desulfurizing dust of coke oven coke guide belongs to the separation type (B01D) of physical or chemical methods. The method solves the disadvantages that the design and arrangement of prior collecting and conveying pipeline are complicated, the operation is inconvenient, the resistance loss is huge, the energy consumption is high, and the investment is huge and the like. A movable bolt and a supporting rod are arranged on a coke guide so as to fix and support a dust hood, and connected with a flue by a movable joint. A draught fan makes the smoke dust generated in the coke guiding process pass through the dust hood for collection, and then the smoke dust enters an internal channel by a U-shaped flue. The smoke gas purified by a plurality of comprehensive effects including spraying, gravity settling and impact wet dedusting and desulfuration and the like enters an external-connected pipe duct for secondary purification, and finally the clean gas reaching the discharge standard is discharged. The water storing bent channel between a baffle plate and the tank bottom is designed in an unobstructed manner so as to ensure that the U-shaped flue is capable of moving in liquid. The invention is matched with the design of movable hanging block, the coke guide is capable of integrally moving to another coke discharge opening under the driving force traction of the coke guide under the premise that the integral smoke dust collecting and conveying system (pipelines and flanges) is not dismounted or reassembled, after finishing the work of collecting smoke dust and dedusting and desulfuration in a charcoal chamber of a coke oven so as to start a next working procedure. The operation in the whole process is simple and practical.

Description

(1) Technical field: [0001] The method for collecting, transporting, dust removing and desulphurizing dust from a coke hauler of the present invention belongs to the separation category of physical or chemical methods (B01D). (two) background technology: [0002] It usually takes 7-15 minutes for each hole of the coke oven to charge coal and take out coke. This process will produce a lot of black smoke, yellow smoke and dust, which contain unburned carbon particles, raw coal gas that is easy to cause explosion (deflagration), Hydrogen and sulfur dioxide, which are seriously harmful to the environment, are therefore very important for their collection, transportation, and treatment. At present, most of the smoke and dust generated during coke blocking in domestic coke ovens have not been effectively treated. Even if some have been treated, they are generally transported by fixed pipelines (see Figure 4), and each corresponding coke outlet hole is designed with fixed flanges a...
