Embodiment
Below in conjunction with embodiment and accompanying drawing thereof, the present invention is illustrated further.
Embodiment 1
Now refer to Fig. 1, Fig. 1 is that the caloric value instrument of the embodiment of the present invention gets source block and base, valve, the connection diagram of bushing and short tube.Caloric value instrument of the present invention gets the online installation method of source block, it is characterized in that comprising the following steps:
A, set up temporary construction facility
In coking subsidiary factory of Baosteel iron making portion first phase coke oven instrument improvement project, need at the upper newly-increased a set of caloric value instrument of first phase coke oven gas pipe (COG).Caloric value instrument is installed, first first must holes on coke oven COG pipeline, install and get source block.
Overhead there is more than 10 meter high owing to getting source block mounting points, in order to ensure construction safety, needing to set up the platform that a band protects to block, simultaneously in order to workmen can flee the scene rapidly when meeting accident, also setting up the passage of an escape on platform side.In order to ensure that workmen can not by gas poisoning, dilution coal gas, needs to place an explosion-proof axial flow fan at the uptake of construction point, and specifies that workmen constructs at the uptake of construction point; When welding base and boring, in order to reduce temperature, two barrels of water also must be prepared.
