Embodiment Construction
[0016] Such as figure 1 As shown, a new type of high-efficiency dust removal and desulfurization integrated system process for tamping coke charging, coal charging and coke discharge ground station, including the following steps:
[0017] (1) The upper part of the furnace door on both sides of the machine coke is equipped with a suction hood. If there is smoke occasionally at a certain furnace door, the butterfly valve here can be opened to suck the smoke into the main flue, preventing the dispersion and diffusion of the smoke. When coal is added, the soot gas emitted by the coke oven enters the regenerative cooler through the coal charging fixed interface valve and the coal charging dust collection pipe from the furnace top smoke guiding vehicle, and is cooled to below 120 ° C; The soot gas enters the regenerative cooler from the suction hood on the upper part of the furnace door through the coal charging dust collection pipe, and is cooled to below 120°C; The coke fixed in...

Abstract
The invention relates to a novel high-efficiency dedusting and desulphurization integrated system process for a coke-tamping, coaling and coke-discharging ground station, comprising the following steps: smoke gas enters a heat accumulating type cooler to be cooled to below 120 DEG C during coal feeding or coke discharging; the cooled smoke gas enters a multifunctional separator and separated tar and a part of large-particle sparkle dust enter a tar settling tank; the smoke gas processed by the multifunctional separator enters a fire resistance bag type dust remover to be filtered; and clean gas is discharged into the atmosphere after filtration. The novel high-efficiency dedusting and desulphurization integrated system process for the coke-tamping, coaling and coke-discharging ground station thoroughly solves the core problems of flammability, explosion proof, hard elimination of toxic gas and high-sulphur coal desulfurization of hard fire cloth bags, tar paste cloth bags and bag-typedust removers, which plague coking enterprises and dust removal enterprises for many years. Proved by practical tests, the dust removal efficiency is more than 99.7 percent, the discharged dust concentration is less than 40mg / m<3>, dust recycled by the ground station is 1400t / a, and smoke and dust are not generated in the production process of a coke oven, thereby completely meeting environmentalrequirements.
Description
technical field [0001] The invention relates to the technical field of environmental protection and dust removal for smoke and dust control in the coking process of a coking plant, in particular to a novel high-efficiency dust removal and desulfurization integrated system process for a ground station for stamping coke, coal charging, and coke discharge. Background technique [0002] At the beginning of the 21st century, our country built a number of tamping coke ovens with a height of 4.3 meters or more. Restricted by various factors at that time, most of the coke ovens used mobile smoke and dust removal vehicles. When only using high-pressure ammonia water to remove dust, the disorderly discharge during coke discharge has made great progress. Due to the increasing number of large coke ovens, government departments have raised the threshold for coking production, stepped up environmental law enforcement, and formulated strict emission standards. Bag dust removal, but due to...
