Description

Technical Field

[0001] This invention relates to the field of activated carbon adsorption equipment technology, and particularly to an activated carbon adsorption device. Background Technology

[0002] Activated carbon adsorption devices are dry waste gas treatment equipment, consisting of a housing and adsorption components filled inside the housing. They come in various specifications based on the number of adsorption components and air volume. Different fillers can be selected to treat various waste gases, mainly including: acidic waste gases and acid mists, alkaline waste gases, organic waste gases, and odors. Activated carbon adsorption devices are particularly suitable for operating environments with low-concentration, high-volume or high-concentration, intermittently emitted waste gases. Major application areas include: electronic component manufacturing, battery manufacturing, pickling workshops, laboratory exhaust, metallurgy, chemical plants, pharmaceutical manufacturing plants, painting workshops, food and brewing, and furniture manufacturing. Activated carbon adsorption devices can be used in conjunction with spray booths, drying rooms, and combined spray and dry booths to treat the generated organic waste gases.

[0003] To achieve better adsorption, two or more adsorption components are usually installed inside the housing. However, due to the multiple adsorption components inside the housing, after a period of use, the adsorption components closer to the air inlet are prone to blockage, while the adsorption components farther away from the air inlet adsorb normally. But because the adsorption components closer to the air inlet are blocked, the adsorption components farther away from the air inlet also cannot be used normally. Summary of the Invention

[0004] The purpose of this invention is to provide an activated carbon adsorption device to solve the problems in the prior art, so that when the adsorption component near the air inlet is blocked, the position of the air inlet can be changed in time.

[0005] To achieve the above objectives, the following technical solution is adopted: an activated carbon adsorption device, comprising a housing, wherein at least two sets of adsorption components are arranged vertically inside the housing, each adsorption component has a mounting hole at its center, and multiple adsorption components are connected to a connecting pipe through the mounting hole. The connecting pipe is open at the top and bottom and located inside the housing, and multiple sets of gas outlet mechanisms are arranged on the side wall of the connecting pipe at different heights. Each set of gas outlet mechanisms is located below the adsorption component adjacent to it. The device also includes a base, on which a driving mechanism for driving the housing to move up and down is provided. A fixed pipe is slidably connected inside the connecting pipe. Both the upper and lower end caps of the housing have sliding holes. Both ends of the fixed pipe extend to the outside through the upper and lower sliding holes respectively. The lower end of the fixed pipe is fixed to the base, and the upper end is closed. Multiple perforations are distributed circumferentially on the side wall of the fixed pipe at the same height. A gas outlet pipe is provided at the top of the housing.

[0006] Preferably, the outer wall of the housing is provided with a plurality of reverse tubes along the vertical direction, each reverse tube being located below the adsorption component adjacent to it, and both the reverse tube and the air outlet tube are provided with electromagnetic valves.

[0007] Preferably, multiple sets of air guide blades are rotatably connected to the connecting pipe, and each set of air guide blades is located below the adsorption component adjacent to it.

[0008] Preferably, a brush is provided on the upper side of each set of air guide blades.

[0009] Preferably, the driving mechanism is an electric telescopic rod.

[0010] Preferably, baffles are provided on both sides of the housing, and the lower ends of the baffles are fixed to the base.

[0011] Preferably, the adsorption assembly includes an outer skeleton and an inner skeleton located in the same plane. The outer wall of the outer skeleton is fitted to the inner wall of the shell, the inner skeleton forms mounting holes, and multiple connecting rods are provided between the outer skeleton and the inner skeleton. All the multiple connecting rods are arranged in the radial direction, and activated carbon blocks are provided in each fan-shaped area formed by the outer skeleton, the inner skeleton and the connecting rods.

[0012] Preferably, an air inlet pipe is fixed on the lower surface of the base, and the air inlet pipe is connected to the lower end of the fixed pipe.

[0013] Preferably, each air outlet mechanism includes multiple air outlets, which are circumferentially distributed on the side wall of the connecting pipe.

[0014] Preferably, the outer surface of the housing is provided with indicator marks.

[0015] The beneficial effects achieved by this invention are as follows:

[0016] The activated carbon adsorption device of the present invention, by setting up mounting holes, connecting pipes, driving mechanisms, fixing pipes, air outlet mechanisms and perforations, enables the housing to move by the driving mechanism when the adsorption component near the air inlet is blocked, thereby changing the position of the air inlet, so that the unblocked adsorption component can adsorb normally, extending the service life and avoiding frequent replacement.

[0023] See appendix Figure 1-4 An activated carbon adsorption device includes a housing 1, within which at least two sets of adsorption components 2 are arranged vertically. In this invention, three sets of adsorption components 2 are used. Each adsorption component 2 has a central mounting hole. Multiple adsorption components 2 are connected to a connecting pipe 3 via the mounting hole. The connecting pipe 3 is open at the top and bottom and located inside the housing 1. Multiple air outlet mechanisms are arranged on the sidewall of the connecting pipe 3 at different heights. Each air outlet mechanism is located below an adjacent adsorption component 2. Each air outlet mechanism includes multiple air outlet holes 13 circumferentially distributed on the sidewall of the connecting pipe 3. The device also includes a base 4, on which a driving mechanism 5, an electric telescopic rod, is provided to drive the housing 1 vertically. A fixed pipe 6 is slidably connected inside the connecting pipe 3. Sliding holes are provided on both the upper and lower end caps of the housing 1. The fixed pipe 6 is divided into two sections at its ends. The fixed tube 6 extends to the outside through two sliding holes at the top and bottom, so that the fixed tube 6 slides and seals with the sliding holes. The lower end of the fixed tube 6 is open to connect to the air intake assembly (air intake pipe 12) and is fixed on the base 4. The upper end is closed. Multiple perforations 7 are distributed around the side wall of the fixed tube 6. The multiple perforations 7 are set at the same height. An air outlet pipe 8 is set on the top of the housing 1. In the initial state, the perforations 7 on the fixed tube 6 are located below the bottom adsorption assembly 2, that is, below the lower end port of the connecting pipe 3. During adsorption, the gas passes through and is adsorbed sequentially from the bottom adsorption assembly 2, the middle adsorption assembly 2, and the top adsorption assembly 2. When the bottom adsorption assembly 2 is blocked, the housing 1 is controlled to move downward by the drive mechanism 5, so that the perforations 7 on the fixed tube 6 are aligned and connected with the air outlet mechanism, i.e., the air outlet 13, located below the middle adsorption assembly 2, thereby changing the air intake position, extending the service time and avoiding blockage.

[0024] In this embodiment, as a preferred embodiment of the above embodiment, the outer wall of the housing 1 is provided with a plurality of reverse tubes 9 in the vertical direction. Each reverse tube 9 is located below the adsorption component 2 adjacent to it, and both the reverse tube 9 and the air outlet pipe 8 are provided with electromagnetic valves. By controlling the corresponding electromagnetic valves, the adsorption component 2 can be reverse flushed. Specifically, purified air is introduced from the air outlet pipe 8, and the housing 1 is moved by the drive mechanism 5 to make the perforation 7 in a blocked state. The corresponding reverse tube 9 can be opened to achieve reverse flushing. When two adjacent reverse tubes 9 are opened, the upper reverse tube 9 can also be introduced with purified air to achieve reverse flushing.

[0025] To ensure more uniform adsorption during the adsorption process, multiple sets of air guide blades 10 are rotatably connected to the connecting pipe 3. Each set of air guide blades 10 is equipped with a brush on its upper side. Each set of air guide blades 10 is located below the adsorption component 2 adjacent to it. The air guide blades 10 rotate when they are connected to the air outlet 13 through the perforation 7 or when the gas is blown from bottom to top, so that the gas enters the adsorption component 2 evenly.

[0026] To improve the stability of the housing during movement, baffles 11 are provided on both sides of the housing 1, and the lower ends of the baffles 11 are fixed to the base 4.

[0027] Specifically, the adsorption component 2 includes an outer frame 201 and an inner frame 202 located on the same plane. The outer wall of the outer frame 201 is fitted to the inner wall of the shell 1. The inner frame 202 forms an installation hole. Multiple connecting rods 203 are arranged between the outer frame 201 and the inner frame 202. All connecting rods 203 are arranged in the radial direction. Activated carbon blocks are arranged in each fan-shaped area formed by the outer frame 201, the inner frame 202 and the connecting rods 203.

[0028] An air inlet pipe 12 is fixed on the lower surface of the base 4, and the air inlet pipe 12 is connected to the lower end of the fixed pipe 6.

[0029] To facilitate the determination of the location of the perforation 7, an indicator mark is provided on the outer surface of the housing 1.
