Description

Technical Field

[0001] This invention relates to the field of methane content control technology, and particularly to a device for controlling the methane content in a shift gas. Background Technology

[0002] A shift gas methane content control device typically involves multiple components for real-time monitoring and adjustment of methane content to ensure gas quality and match the required reaction conditions.

[0003] Existing technologies, such as the invention with publication number CN119281247A, disclose a product quality control device for a methanation unit. This patent includes a production system, a distributed control system, and an advanced control system. The production system includes a gasification unit for conveying crude coal gas to a shift converter, which converts the crude coal gas, and the resulting shifted gas is conveyed to a purification unit for purification. The resulting feed gas is then conveyed to the methanation unit for methanation to obtain the finished product gas. The distributed control system collects the hydrogen-to-carbon ratio of the shifted gas output from the shift converter, the feed gas specific gravity of the feed gas output from the purification unit, and the hydrogen content of the finished product gas. The advanced control system determines the valve increment based on the hydrogen-to-carbon ratio, feed gas specific gravity, and hydrogen content. Applying the solution provided in this application's embodiments enables precise control of the methanation production process, ensuring that the quality of the finished gas meets process requirements.

[0004] Shift gas is an important intermediate product in coal chemical or synthetic ammonia industries. The methane content directly affects the efficiency and safety of subsequent processes. As the core reaction equipment, the gasifier's internal wall temperature has a significant impact on the methane generation reaction: excessively high temperatures can easily lead to methane cracking or coking, while excessively low temperatures may inhibit the methanation reaction, resulting in fluctuations in product composition. Traditional gasifier temperature control often relies on external heating / cooling jackets or adjusting feed conditions, which has shortcomings such as slow response, low control accuracy, and large modifications to the furnace body.

[0026] Compared with related technologies, the shift gas methane content control device provided by the present invention has the following beneficial effects: This invention provides a methane content control device for shift gas. When it is necessary to control the methane content on the inner wall of the gasifier, the temperature of the inner wall of the gasifier can be controlled by an adjustment device to regulate the methane content. First, the positioning plate is precisely inserted into the inner wall of the positioning groove. During the insertion process, the positioning block on the surface of the positioning plate will drive the limiting plate to slide in along the inner wall of the auxiliary groove. At this time, the magnetic adsorption design of the limiting plate makes it quickly and firmly magnetically connected to the connecting plate on the inner wall of the auxiliary groove. The limiting block on the surface of the limiting plate is precisely inserted into the auxiliary groove of the auxiliary plate to ensure... After accurate alignment, the positioning shaft is rotated along the surface of the positioning plate, driving the positioning rod to move precisely until one end of the positioning rod is perfectly inserted into the positioning hole on the inner wall of the positioning groove. At this point, the positioning plate and auxiliary plate are securely installed. Then, the control panel is activated to start adjusting the temperature of the auxiliary plate. At this time, with the help of the excellent thermal conductivity of the graphene material of the auxiliary plate, the inner wall temperature of the gasifier can be efficiently adjusted to ensure the optimal conditions for gas reaction. Thus, the overall operation process of the adjustment device is successfully completed. By operating the adjustment device, the methane content on the inner wall of the gasifier can be controlled.

[0027] When it is necessary to dilute the methane content inside the gasifier, an auxiliary device can be installed to introduce air into the inner wall of the gasifier to dilute the methane concentration. First, precisely insert the connecting frame along the surface of the air inlet pipe. At this time, the connecting plate on the inner wall of the connecting frame will be securely inserted into the inner wall of the connecting groove until the sealing ring on the inner wall of the connecting frame is in firm contact with the surface of one end of the air inlet pipe, ensuring that there is no gas leakage. Next, by using the return torsion force of the coil spring, the connecting column is rotated along the arc surface of the connecting rod, thereby driving the adjusting rod to rotate accordingly until one end of the adjusting rod is perfectly connected with the inner wall of the fixed frame. At this time, the adjusting rod is rotated along the arc surface of the connecting rod. Gently rotate the connecting shaft on the arc surface of the linkage to move the auxiliary pad to a precise position until one end of the auxiliary pad abuts against the surface of the fixed frame, completing the stable connection between the connecting frame and the air inlet pipe. At this point, turn the hand valve to start the air extraction pipe, allowing air to flow into the gasifier along the inner wall of the connecting pipe for effective dilution. During this process, it is especially important to use a filter screen to purify the incoming air to ensure that the introduced air does not contain impurities and to ensure a clean environment inside the gasifier. The entire operation process of the auxiliary device is now complete. By operating the auxiliary device, the methane content on the inner wall of the gasifier is diluted.

[0028] When using the gasifier for reaction, the observation device can be used to observe the internal conditions. First, overcome the tension of the spring and carefully pull the fixing rod along the surface of the adjusting frame. This will move the adjusting block precisely until it reaches the appropriate position. Then, carefully insert the limiting frame along the surface of the fixing frame to ensure a stable installation and that the adjusting plate and adjusting groove are perfectly engaged. Next, easily release the fixing rod, allowing the spring's rebound force to accurately engage the adjusting block along the inner wall of the fixing groove, successfully completing the installation of the connecting frame. Finally, through the transparent and heat-resistant fixing plate, the operator can clearly observe the environmental changes inside the gasifier, monitor the reaction in real time, and provide reliable data support for subsequent operations. The operation of the observation device is thus successfully completed, facilitating convenient observation of the gasifier's internal structure during operation. Attached Figure Description
