Problems solved by technology

During this period, the experimental site needs to be isolated to prevent accidents, and personnel cannot enter the site to replace the pipeline due to continuous gas generation
The semi-focus produced by the experiment is difficult to remove, and such shutdown also prolongs the experiment cycle

Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0035] The embodiments of the present invention take the 40kg small coke oven as an example, the fluid generating device is the coal screen 1 of the coke oven heating furnace; the fluid receiving device is the gas cooler 4, and the experimental process of the 40kg small coke oven produces coal gas from the coal screen 1, and the gas To the gas cooler 4 for cooling.

[0036] Such as figure 1 As shown, in the prior art, one end of the original pipeline 2 is connected to the gas outlet 101 of the coal mine 1, and the other end is connected to the gas inlet 401 of the gas cooler 4, and is tightened with a turnbuckle. During the experiment, when the original pipeline 2 gas leaks (such as corrosion and damag...

Abstract

The invention discloses a real-time pipeline replacement method and real-time pipeline replacement system for a coke oven. The system comprises a fluid generating device, an original pipeline, a firstthree-way valve, a second three-way valve and a fluid receiving device. The invention also discloses a method for replacing the pipeline in real time for the coke oven, which comprises the followingsteps of: when gas leakage occurs in the original pipeline, connecting one end of the standby pipeline to the third connecting port, connecting the other end of the standby pipeline to the sixth connecting port, and opening the third ball valve and the fourth ball valve, or, when the standby pipeline is connected to the third connecting port and the sixth connecting port, directly opening the third ball valve and the fourth ball valve, and closing the first ball valve and the second ball valve. According to the method and the system, the pipeline replacement time is short, the efficiency is high, and the risk that coal gas pollutes the environment is reduced. The pipeline can be replaced without stopping the experiment, so that the experiment efficiency is greatly improved, and unnecessaryresource waste is reduced.

Description

technical field [0001] The invention relates to the field of coke oven transformation in the coking industry, and more particularly, relates to a method for real-time replacement of pipelines for coke ovens and a system for real-time replacement of pipelines. Background technique [0002] In the coking industry, many coke manufacturers and colleges specializing in coal coking basically have a set of 40kg small coke oven experiment system. By adjusting the weight of the coal sample, it is possible to effectively simulate the coking process of coke ovens with different volumes and provide homogeneous coke that represents the average quality of the coke ovens produced; A complete and accurate evaluation of the coking performance can be made to accurately and quantitatively predict the coke reactivity and post-reaction strength of the coke oven produced. [0003] However, as the number of small coke oven experiments increases, gas pipes will be corroded and perforated, and gas ...
