Description

Technical Field

[0001] This utility model relates to a connecting device, and more particularly to a connecting device for coking VOCs gas to enter a coke oven, belonging to the field of mechanical design and manufacturing technology. Background Technology

[0002] High-oxygen waste gas (VOCs) generated in coking processes such as cold drum, desulfurization, ammonium sulfate production, and ammonia stripping needs to be collected and treated in a scrubbing tower before being sent to the coke oven for combustion. Current technology primarily involves introducing VOCs waste gas by creating openings in the coke oven waste gas switch. This also requires a separate VOCs reversing rod connected to the coke oven waste gas tie rod. Furthermore, the waste gas switch is made of special materials, resulting in significant construction difficulties, slow progress, and potential leaks. The additional VOCs reversing rod also increases the load on existing coke oven heating equipment such as the waste gas tie rod and hydraulic cylinders, potentially causing tie rod breakage and cylinder malfunctions, thus posing a threat to the safe and stable production of the coke oven. Therefore, it is necessary to improve the existing technology. Summary of the Invention

[0003] To address the problems of high construction difficulty, slow progress, and significant safety risks associated with introducing VOCs waste gas by drilling holes in the coke oven exhaust gas switch, as well as the issues that connecting the VOCs reversing tie rod to the sector wheel on the exhaust gas switch or the coke oven exhaust gas tie rod can easily lead to breakage of the coke oven exhaust gas tie rod and failure of the hydraulic cylinder equipment, this utility model provides a connection device for introducing coking VOCs gas into the coke oven.

[0004] This utility model is achieved through the following technical solution: a connection device for direct entry of coking VOCs gas into the coke oven, comprising a VOCs gas main pipe and a coke oven exhaust gas switch, characterized in that it further comprises a main connecting pipe, a branch connecting pipe, and a valve, wherein one end of the main connecting pipe is connected to the VOCs gas main pipe, and the other end is connected to the cleaning hole on the double fork of the flue of the coke oven exhaust gas switch through the branch connecting pipe, and the original cleaning hole of the double fork of the coke oven exhaust gas switch, so that VOCs gas can be directly sent into the coke oven for combustion through the coke oven exhaust gas switch via the main connecting pipe, the branch connecting pipe, and the original cleaning hole of the double fork of the coke oven exhaust gas switch, without the need for drilling operations on the coke oven exhaust gas switch, effectively solving many problems caused by drilling operations on the coke oven exhaust gas switch in the prior art, and also eliminating the need to set up a separate VOCs reversing tie rod, thus avoiding the breakage of the coke oven exhaust gas tie rod and the failure of the hydraulic cylinder equipment.

[0005] Furthermore, the input end of the main connecting pipe is connected to the VOCs gas main pipe through a metal flexible hose, and the output end of the main connecting pipe is connected to the branch connecting pipe, so as to eliminate the stress caused by displacement between pipes through the buffering effect of the metal flexible hose, and prevent the pipe from deforming and cracking under stress.

[0006] Furthermore, the branch connecting pipe is configured as a tee pipe. The first port of the tee pipe is connected to the output end of the main connecting pipe, and the second and third ports of the tee pipe are respectively connected to the two cleaning holes at the lower part of the flue double fork on the coke oven exhaust gas switch. This allows VOCs gas to be sent into the coke oven for combustion through the two cleaning holes at the lower part of the flue double fork on the exhaust gas switch via the connection between the branch connecting pipe and the two cleaning holes at the lower part of the flue double fork on the exhaust gas switch. This avoids the problems of high construction difficulty, slow progress, and high safety risks associated with drilling operations on the exhaust gas switch.

[0007] Furthermore, the valve is configured as a wafer butterfly valve.

[0008] Multiple connection devices are provided for the coking VOCs gas to directly enter the coke oven, and the specific number is set according to the needs of coking VOCs gas recovery.

[0009] This utility model has the following advantages and effects: By adopting the above solution, after conveniently setting this connecting device between the VOCs gas main pipe and the coke oven exhaust gas switch, the VOCs gas can be directly sent into the coke oven for combustion through the coke oven exhaust gas switch. There is no need to perform hole-making operations on the coke oven exhaust gas switch, which effectively solves many problems caused by hole-making operations on the coke oven exhaust gas switch in the prior art. There is also no need to set up a separate VOCs reversing tie rod, which will not cause the coke oven exhaust gas tie rod to break or the hydraulic cylinder equipment to malfunction, ensuring the safe and stable production of the coke oven and allowing the VOCs gas to smoothly enter the coke oven for combustion.
