Coke oven riser tube replacement apparatus and coke oven riser tube replacement method

Abstract

The invention provides a coke oven riser tube replacement apparatus and a coke oven riser tube replacement method, and especially relates to a coke oven riser tube replacement apparatus and a coke oven riser tube replacement method applied in the field of coke oven production. The coke oven riser tube replacement apparatus provided by the invention has the advantages of simple structure, shortening of the unkeeping time, and maintenance of the coke oven production continuity, and comprises a coal car, a fixed stand column, a rotating stand column, a crane and a transverse arm. The coke oven riser tube replacement method can reduce the danger of replacement working, and comprises the following steps: 1, rotating the transverse arm to a position above a riser tube to be replaced; 2, hoisting the riser tube to be replaced; 3, moving out the riser tube to be replaced; 4, moving a new riser tube to a position to be installed, and installing; 5, rotating the transverse arm to the initial position, and fixing. A rotatable cantilever crane in the invention has the advantages of simple structure, low cost, realization of no influences on the use performances of the coal car, coal car walking or normal production of a coke oven after installation, and flexible usage.

Description

technical field [0001] The invention relates to a coke oven rising tube replacement device and a coke oven rising tube replacement method, in particular to the coke oven rising tube replacement device and the coke oven rising tube replacement method applied in the field of coke oven production. Background technique [0002] During the long-term production process of the coke oven, the rising pipe of the coke oven is affected by the frequent start and stop of circulating ammonia water and the corrosive substances in the gas, and frequent cracks and corrosion holes occur, which not only deteriorates the coke oven operating environment, corrodes the iron parts of the furnace, and Cause a large amount of raw gas loss. With the increase of the age of the coke oven, the degree of damage to the raw gas exporting equipment is increasing year by year, which seriously affects the clean production of the coke oven, and the rising pipe on the coke side of the coke oven must be replaced....

AI Technical Summary

Problems solved by technology

Due to the large volume of the riser, each riser weighs 700-800kg, and the replacement position is narrow, it is difficult to replace the riser

Traditionally, large and medium-sized cranes are used to replace the rising pipe of coke oven. The cost of renting a large crane is high, and the furnace roof is narrow and close to the gas collecting pipe. The pipeline is complicated, and there is a large safety risk during operation.

Therefore, there is no one in the prior art that is simple in structure, low in cost, does not affect the normal production of the coke oven, and can save a lot of manpower, material resources, and financial resources, greatly shortens the maintenance time, maintains the continuity of coke oven production, and reduces the cost of coke oven production.
