Problems solved by technology
Due to the normal production in the construction area, frequent movement of coal loading trucks and coke pushing trucks, high temperature, heavy dust, and lack of gas, smoke, dust, and exhaust gas leak when the riser pipe is damaged, causing serious environmental pollution. riser
When the riser pipe is replaced, it involves the lack of gas in the riser pipe, and the contained CO and other gases will cause construction personnel to suffocate. It is especially important to choose the replacement time, which requires construction personnel to have professional skills and corresponding safety measures. The replacement time is long, usually at least 3 hours, and there may be high temperature burns during the construction process, which poses serious safety hazards

Embodiment Construction
[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0020] The installation method of the riser heat exchanger includes the following steps:
[0021] Step a, pretreatment of riser heat exchanger: At the end of coking, specifically 4 hours after the end of coking, and 2 hours before coking, connect the original riser heat exchanger with the spare riser base and the tee pipe; turn off the gas turning board, open the cover of the riser pipe, and there is a CO alarm at the cover of the riser pipe; pry open a coal charging hole cover, and use compressed air to blow down from the riser pipe; the air outlet of the riser pipe is connected to an exhaust fan, and the exhaust The outlet of t...

The invention belongs to the technical field of ascent tube installation, and particularly relates to an ascent tube heat exchanger installation method. The ascent tube heat exchanger installation method comprises the steps of ascent tube heat exchanger pretreatment, associated component detachment, replacement of an ascent tube heat exchanger, associated component recovery and ascent tube sealingtreatment. In ascent tube heat exchanger pretreatment, the selected replacement time is the 3.5 hours to 4.5 hours at the final stage of coking and 1.5 hours to 3 hours before coke push. During ascent tube heat exchanger pretreatment, an original ascent tube heat exchanger, a standby ascent tube base and a three-way tube need to be connected in a communication manner. By adopting the ascent tubeheat exchanger installation method for installation the ascent tube heat exchanger, the appropriate time for replacing the heat exchanger is selected, and it is avoided that high-concentration harmfulgas causes harm to human bodies; and the operation of replacing an ascent tube is simple and convenient to carry out, and the replaced ascent tube is good in sealing performance and is good in safetyperformance.
Description
technical field [0001] The invention belongs to the technical field of rising tube installation, and in particular relates to a method for installing a rising tube heat exchanger. Background technique [0002] The rising pipe is installed on the top of the coke oven, and is used to lead out the coke oven process equipment for carbonizing the raw gas in the chamber. Due to the normal production in the construction area, frequent movement of coal loading trucks and coke pushing trucks, high temperature, heavy dust, and lack of gas, smoke, dust, and exhaust gas leak when the riser pipe is damaged, causing serious environmental pollution. riser tube. When the riser pipe is replaced, it involves the lack of gas in the riser pipe, and the contained CO and other gases will cause construction personnel to suffocate. It is especially important to choose the replacement time, which requires construction personnel to have professional skills and corresponding safety measures. It take...
