Embodiment Construction
[0055] The present invention will be further described below in conjunction with the accompanying drawings.
[0056] 1. Project content
[0057] On-site situation: There are two coke ovens, namely 1# and 2# coke ovens 20, which are located on both sides of the coal tower 19. There is a coal charging car track 16 on the top of the furnace, and the end platforms on both sides of the coke oven have resistance walls 18 .
[0058] The coke oven fugitive smoke and dust collection and treatment device is composed of two dust collection hoods, dust removal pipes, dust removal ground station and other parts.
[0059] Each dust collection hood has a total length of 95.36 meters and a span of 81.36 meters. The installation height is 23.78 meters, the supporting beam is 2.5 meters high, and the total weight of the dust collecting hood is about 460t. The weight is evenly distributed on the 4 supporting columns, and the top is tensioned by a cable stay to prevent the middle of the dust c...

The invention aims at providing a method for assembling a suspended cable type dust cage for a coke oven, which can save assembling time and is quick in construction and safe in operation under a condition that the coke oven is not shut down. The method comprises the following steps: fixing supporting columns on a resistance wall, setting a strengthening beam and a strengthening ring beam for a coal tower, and assembling a cable holder on the strengthening beam; assembling an assembly trolley capable of moving on a larry car rail; assembling the first section of a dust cage on the assembly trolley, pushing a first supporting cross beam to the side part of the coal tower, putting the first supporting cross beam on the two supporting columns, and assembling the first section of the dust cage; fixedly connecting the front end of the first section of the dust cage to the strengthening beam; assembling the intermediate section of the dust cage on the assembly trolley, pushing to the assembly position, and suspending the intermediate section of the dust cage on the cable holder through a cable; and finally, assembling the tail section of the dust cage on the assembly trolley, pushing to the assembly position together with a second supporting cross beam, putting the second supporting cross beam on the two supporting columns through a jack, and assembling the tail section of the dust cage.
Description
technical field [0001] The invention relates to an installation method of a coke oven fugitive dust collection device, in particular to an installation method of a cable-suspended dust collection hood of a coke oven under the condition of non-stop production. Background technique [0002] A company's 1.2 million tons / year coking project started construction in 2011 and was put into operation in 2012. The distance between the two 6m coke ovens and the surrounding villages is greater than 1.2km, meeting the requirements of environmental protection regulations at that time. However, in recent years, with the gradual improvement of national environmental protection standards and the consideration of a company's long-term development, in the spirit of green development and social responsibility, it plans to install a coke oven fugitive smoke collection and treatment device. [0003] This project belongs to the environmental protection project. During the normal production proces...
