Technical Field

[0001] The utility model relates to the technical field of resources and environment - air pollution control, and particularly relates to a novel activated carbon filter for natural gas. Background Technique

[0002] Air pollution is caused by certain substances entering the atmosphere due to human activities or natural processes, presenting a sufficient concentration for a sufficient time, and thus endangering human comfort, health, and welfare or the realization of the environment. Natural gas refers to a mixture of hydrocarbon and non-hydrocarbon gases naturally occurring in underground strata. Its main use is as fuel, and it can be used to manufacture carbon black, chemical drugs, and liquefied petroleum gas. Propane and butane produced from natural gas are important raw materials for modern industry. During the processing and transportation of natural gas, an activated carbon filter is required to filter it.

The currently common structure is a packed activated carbon type. When the adsorption capacity of the activated carbon reaches the requirement, the activated carbon filter material needs to be replaced. Due to the packed structure during the installation of the activated carbon, it is time-consuming and laborious to replace. In addition, there are gaps between the activated carbon particles, resulting in an unsatisfactory adsorption effect. Moreover, once air leakage occurs at the interface of some activated carbon filters, it is not easy to detect and maintain in a timely manner.

Both the gas detection module 20 and the alarm module 19 are connected to the control end of the filtering device;

[0026] Specifically, as Figure 1 andFigure 3 As shown, the first sealing ring 16 and the second sealing ring 18 on the connecting pipe 2 and the intake pipe 17 are closely attached to achieve sealing. Once natural gas leaks at the connection, the gas detection module 20 can detect the natural gas leakage in time, and then the alarm module 19 alarms the control terminal to remind the staff to repair.

There are three groups of support skeletons 11 and they are annularly installed inside the filter frame 4. Threaded sealing grooves are arranged inside both the first sealing cover 8 and the second sealing cover 12.

[0028] Specifically, as Figure 1 and Figure 2 shown, the activated carbon filter element 5 adopts a columnar sintered structure. The activated carbon filter element 5 is sintered as a whole, which is convenient and quick to take out and replace during replacement.

When limiting, first pull down the adjusting rod 23. When the adjusting rod 23 drives the limit plate 9 to move to fit the top of the filter rack 4, the clamping plate 6 at the bottom of the limit plate 9 can clamp both sides of the filter rack 4. Then, tightening the locking bolt 22 can achieve the limit. The activated carbon filter element 5 adopts a columnar sintered structure. The activated carbon filter element 5 is sintered as a whole, which is convenient and fast to take out and replace during replacement. Moreover, the gaps between the activated carbon particles of the columnar sintered activated carbon filter element 5 become smaller, with reliable sealing and better adsorption effect. The first sealing ring 16 and the second sealing ring 18 on the connecting pipe 2 and the air inlet pipe 17 are closely attached to achieve sealing.
