Description

Technical Field

[0001] This utility model belongs to the field of adsorption tower technology, specifically relating to an activated carbon adsorption tower. Background Technology

[0002] Activated carbon adsorption towers are dry waste gas treatment devices, mainly composed of a housing and internally filled activated carbon adsorption units. Utilizing the high specific surface area and porous structure of activated carbon, they efficiently remove organic pollutants and some inorganic harmful gases from waste gas through the synergistic effect of physical and chemical adsorption. Designed for industrial environments with low-concentration, high-volume emissions or high-concentration, intermittent emissions, they are widely used in waste gas purification in industries such as chemical, electronics, coating, pharmaceutical, and food processing, and can meet stringent emission standards.

[0003] One activated carbon adsorption tower, with announcement number CN222723911U, addresses the issue of low gas filtration efficiency when only one chamber is functioning normally during replacement. This tower utilizes an adsorption assembly and an adsorption disassembly assembly. The disassembly assembly seals only one-quarter of the entire tower, allowing disassembly of the remaining three-quarters, which are then protected by a shielding plate. Simultaneously, the normal adsorption and filtration flow of the remaining three-quarters is increased from one-quarter to three-quarters, thus improving the tower's gas treatment efficiency. However, the rotating filter element in this design causes friction between the filter element and the adsorption tower during rotation. Over time, this friction can create gaps between the filter element and the tower, affecting filtration efficiency and potentially leading to gas leakage. Utility Model Content

[0004] To address the problem in existing technologies where gaps exist between the filter element and the adsorption tower, affecting filtration efficiency and potentially causing gas leakage, this invention provides an activated carbon adsorption tower. This tower employs a parallel design of a main tower and a secondary tower, ensuring airtightness while resolving the gas treatment issue during activated carbon replacement. The specific technical solution is as follows: An activated carbon adsorption tower includes: an adsorption tower body; an inlet pipe installed on the lower wall of the adsorption tower body; an outlet pipe installed on the upper wall of the adsorption tower body; a secondary adsorption tower structure installed on the side wall of the adsorption tower body; several adsorption structures installed inside the adsorption tower body; and a sealing structure movably installed outside the adsorption tower body. The secondary adsorption tower structure includes: a secondary inlet pipe, a secondary outlet pipe, and a secondary adsorption tower body; one end of the secondary inlet pipe is connected to the inlet pipe, one end of the secondary outlet pipe is connected to the outlet pipe, and the secondary adsorption tower body is installed between the secondary inlet pipe and the secondary outlet pipe.

[0005] Preferably, the adsorption structure includes: two adsorption supports and adsorption activated carbon; the two adsorption supports are respectively installed on the inner wall of the adsorption tower body, and the adsorption activated carbon is movably installed between the two adsorption supports.

[0006] Preferably, the sealing structure includes: a sealing plate, a plurality of sealing bolts, and a plurality of sealing nuts; the sealing plate is movably installed inside the adsorption tower body, and the sealing plate is connected to the adsorption tower body by a plurality of sealing bolts and a plurality of sealing nuts.

[0007] Preferably, isolation valves are provided on the outside of the secondary inlet pipe and the secondary outlet pipe.

[0008] Preferably, isolation valves are provided on the outside of the inlet and outlet pipes of the adsorption tower body.

[0009] Preferably, a sealing strip is provided between the sealing plate and the adsorption tower body.

[0010] Preferably, an exhaust pump is provided outside the discharge pipe of the adsorption tower body.

[0011] The activated carbon adsorption tower of this utility model has the following advantages compared with the prior art: the activated carbon adsorption tower solves the problem of waste gas treatment when replacing activated carbon through the design of a main tower and a secondary tower; the parallel main tower and secondary tower are controlled by an isolation valve, which allows the waste gas to be purified and discharged through one of the two towers. When the main tower is under maintenance, the secondary tower is used for purification, which not only does not affect the filtration efficiency of the waste gas, but also ensures that the waste gas will not leak.

The present invention provides a technical solution: an activated carbon adsorption tower, comprising: an adsorption tower body 1, an inlet pipe installed on the lower wall of the adsorption tower body 1, an outlet pipe installed on the upper wall of the adsorption tower body 1, a secondary adsorption tower structure installed on the side wall of the adsorption tower body 1, a plurality of adsorption structures installed inside the adsorption tower body 1, and a sealing structure movably installed outside the adsorption tower body 1; the secondary adsorption tower structure comprises: a secondary inlet pipe 2, a secondary outlet pipe 3, and a secondary adsorption tower body 4; one end of the secondary inlet pipe 2 is connected to the inlet pipe, one end of the secondary outlet pipe 3 is connected to the outlet pipe, the secondary adsorption tower body 4 is installed between the secondary inlet pipe 2 and the secondary outlet pipe 3, an isolation valve 10 is provided outside the secondary inlet pipe 2 and the secondary outlet pipe 3, an isolation valve 10 is provided outside the inlet pipe and the outlet pipe of the adsorption tower body 1, a sealing strip is provided between the sealing plate 7 and the adsorption tower body 1, and an exhaust gas pump 11 is provided outside the outlet pipe of the adsorption tower body 1.

[0014] As a preferred embodiment, further, the adsorption structure includes: two adsorption supports 5 and adsorption activated carbon 6; the two adsorption supports 5 are respectively installed on the inner wall surface of the adsorption tower body 1, and the adsorption activated carbon 6 is movably installed between the two adsorption supports 5.

[0015] As a preferred embodiment, the sealing structure further includes: a sealing plate 7, a plurality of sealing bolts 8 and a plurality of sealing nuts 9; the sealing plate 7 is movably installed inside the adsorption tower body 1, and the sealing plate 7 is connected to the adsorption tower body 1 by the plurality of sealing bolts 8 and the plurality of sealing nuts 9.

[0016] Working principle: Before using this device, the exhaust gas pipe and the inlet pipe of the adsorption tower body 1 need to be connected, and an external AC power supply needs to be connected to the exhaust gas pump 11 to provide energy for the operation of the exhaust gas pump 11.

[0017] This device has two operating modes: normal use and maintenance.

[0018] During normal operation, the isolation valves 10 of the inlet and outlet pipes of the adsorption tower body 1 are open, while the isolation valves 10 of the secondary inlet pipe 2 and secondary outlet pipe 3 are closed. Simultaneously, the exhaust gas pump 11 is turned on. Waste gas enters the adsorption tower body 1 through the outlet pipe and exits through the outlet pipe. The waste gas is purified by passing through the activated carbon 6 before being discharged.

[0019] During maintenance, the isolation valves 10 of the inlet and outlet pipes of the adsorption tower body 1 are closed, while the isolation valves 10 of the secondary inlet pipe 2 and secondary outlet pipe 3 are opened. Simultaneously, the exhaust pump 11 is turned on. The waste gas passes through the secondary inlet pipe 2, the secondary adsorption tower body 4, and the secondary outlet pipe 3, finally exiting through the outlet pipe of the adsorption tower body 1. As the waste gas passes through the secondary adsorption tower body 4, it is purified by the activated carbon within it. At this time, the adsorption tower body 1 can be cleaned and maintained. First, several sealing bolts 8 and several sealing nuts 9 are removed. Then, the sealing plate 7 is removed. The operator then removes the saturated activated carbon 6 and reinstalls new activated carbon 6 into the two adsorption supports 5. Simultaneously, the operator reinstalls the sealing plate 7 into the adsorption tower body 1 using the sealing bolts 8 and sealing nuts 9. The adsorption tower body 1 can then resume operation.
