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:
Coke guide flue dust of the present invention moves to collect and carries and dust-collecting sulfur-removing method, belongs to the separation class (B01D) of physics or chemical method.
(2) background technology:
Each hole of coke oven time of the discharging of the coke of coalingging was generally 7-15 minute, this course of work can produce a large amount of black smokes, tobacco and dust, wherein contain unburnt carbon granule, the raw coke oven gas of set off an explosion easily (detonation), hydrogen and the sulfur dioxide etc. that environment had serious harm, therefore very important to its collection, conveying, processing.The flue dust that present domestic coke oven produces when blocking Jiao is not effectively handled mostly, even what have handles, also generally adopt fixed-piping to carry (see figure 4), the equal designs fix flange in every corresponding hole of the discharging of the coke, flange plate, set bolt dock with dust shield pipe flange on the coke guide.When collect certain hole block the flue dust of Jiao's (discharging of the coke) process the time, with the flange plate in corresponding fixed ducts road open, allow the dust shield pipe flange in the mounting flange and the coke guide sky dock, be connected and fixed with set bolt, the flange plate in the fixed ducts road when other is not discharged of the coke is closed.Then dusty gas being transported to dusting and desulfuring system purifies.When needs move to 4.3 when the discharging of the coke hole 2 from 4.3 holes 1 of the discharging of the coke, adpting flange 4.6 dismountings need be covered (analogizing in proper order) with the 4.6.1 flange plate; Therefore it is complicated that the method has the pipeline designs laying, operation inconvenience; Drag losses is big, and power consumption is high, invests shortcomings such as big.
(3) summary of the invention:
The coke oven barrier flue dust that the present invention proposes moves collection conveying and dust-collecting sulfur-removing method, is exactly that the existing feed-line of collecting of solution designs the laying complexity, operation inconvenience; Drag losses is big, and power consumption is high, invests shortcomings such as big.
Its technical scheme is as follows:
1. the coke oven barrier flue dust moves to collect and carries and dust-collecting sulfur-removing method (Fig. 1), on coke guide 3, establish dust shield 7, by air-introduced machine 10 and flue 9, it is indoor that dusty gas enters dust-removal and desulfurizing from dusty gas import 11, contact after-purification with the atomized liquid point that contains desulfurizing agent of shower nozzle 14 ejections, it is characterized in that this method also comprises the following steps:
