Description

Technical Field

[0001] The utility model relates to the technical field of waste gas purification, in particular to an RCO catalytic combustion device. Background Art

[0002] RCO catalytic combustion equipment is a new type of environmentally friendly energy-saving product. It uses a high-energy ratio activated carbon adsorption bed and a catalyst bed to purify the organic waste gas under the action of the catalyst before discharging it. The principle of RCO catalytic combustion equipment: The activated carbon adsorption method uses the physical adsorption of porous activated carbon (mainly carbon) to adsorb pollutants in organic waste gas onto its surface to achieve purification. Since the reaction temperature of this method is relatively low (generally 200-300°C), energy consumption can be reduced and purification efficiency can be improved. The RCO catalytic combustion treatment device generally needs to pass through a cyclone spray tower, a dry filter box, an activated carbon adsorption bed, a combustion furnace, and an exhaust chimney in sequence. In the prior art, the dry filter box and the activated carbon adsorption bed need to be cleaned or the filter element replaced after filtering for a period of time at one end. After searching, a Chinese patent with publication number CN220471644U discloses an RCO catalytic combustion device, including a dry filter box, an air inlet and an air outlet are respectively provided at both ends of the dry filter box, a double-channel structure is arranged inside the dry filter box, a valve plate is movably installed at one end of the double-channel structure in the dry filter box, and a plurality of filter components are movably installed in the double-channel structure of the dry filter box, and the interior of the dry filter box is divided into a plurality of filter components by a partition plate. The double-channel structure consisting of the upper channel and the lower channel is further rotatably installed with a valve plate at one end of the partition to ensure that one of the upper and lower channels works normally during operation. If the filter element needs to be replaced, the valve plate is driven by the cylinder to close one of the upper and lower channels to ensure that one of the groups can continue to perform filtering work normally, and the inside of one group of channels is closed to replace or clean the filter element. Compared with the traditional device, the filter element can be replaced without stopping the machine. Although the filter element can be replaced without stopping the machine, the replacement requires replacing the filter channel to replace the filter element. The overall structure is large and complex, and the production is relatively large. At the same time, the double filter channels increase the risk of gas leakage. Therefore, an RCO catalytic combustion device with a single filter channel and filter element replacement without stopping the machine is designed, which reduces the overall volume while reducing the manufacturing cost and the risk of gas leakage.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example:

[0022] See also Figure 1-4A RCO catalytic combustion device comprises a filter box 1 symmetrically connected with connecting pipes 2 on the left and right sides, a rotating ring 3 having four groups of circumferentially evenly distributed spacers 4 is rotatably connected in the filter box 1, and also comprises four groups of filter frames 5 which can be separately arranged and slidably arranged between two adjacent spacers 4, a filter element 6 is fixedly installed on the filter frame 5, a top plate 9 which is sealingly and slidably matched with four spacers 4 and four filter frames 5 is arranged at the top of the rotating ring 3, the top plate 9 is fixedly connected to the filter box 1, and two side baffles 8 which are symmetrically arranged and have a width greater than the width of the filter frame 5 are fixedly connected to the bottom of the top plate 9, and the two side baffles 8 are symmetrically arranged on both sides of the connection line of the two connecting pipes 2, the side baffles 8, the filter box 1 and two adjacent side baffles 8 can form a replacement space, and a rotating adjustment mechanism for driving the rotating ring 3 and the four filter frames 5 to rotate is also arranged on the filter box 1.

[0023] Specifically, the rotation adjustment mechanism includes a mounting frame 10 fixedly mounted on the top of the filter box 1, the top plate 9 is fixedly connected to the mounting frame 10, and a connecting shaft 12 that is sealed and passes through the top plate 9 is rotatably connected to the mounting frame 10. The bottom of the connecting shaft 12 is fixedly connected to the bottom of the rotating ring 3 through a rotating plate 7. A driving member for driving the connecting shaft 12 to rotate is provided on the mounting frame 10. By starting the driving member, the output shaft of the driving member is rotated ninety degrees, which can drive the rotating ring 3 and the four filter frames 5 and the four filter elements 6 to rotate ninety degrees as a whole. By setting the mounting frame 10, the stability of the top plate 9 is increased while facilitating the installation of the driving member.

[0024] Specifically, the filter element 6 is configured to be an arc-shaped structure, and a filter residue gap is provided between the outer wall of the filter element 6 and the outer wall of the filter frame 5. By configuring the filter element 6 to be an arc-shaped structure, the filtration area is increased and the filtration effect is improved. By configuring the filter residue gap, it is convenient for the filter residue adhered to the filter element 6 to enter the replacement space as it rotates, thereby preventing it from being scraped off when passing through the gap between the side baffle 8 and the filter box 1.

[0025] Specifically, a plurality of lifting grooves 13 are provided on the top of the filter frame 5. The provision of the lifting grooves 13 facilitates lifting the filter frame 5 from the replacement space by means of a hook.

[0026] Specifically, the connecting pipe 2 is provided with a flaring structure, the side with a larger flaring on the connecting pipe 2 is fixedly connected to the filter box 1, and the side with a smaller flaring on the connecting pipe 2 is fixedly connected with a flange. The filtration area of ​​the filter element 6 is increased through the flaring structure, so that the filter element 6 can be fully utilized as much as possible. By setting the flange, the pipeline can be easily connected.

[0027] Specifically, the driving member includes a rotating motor 11 fixedly mounted on the mounting frame 10, and the output shaft of the rotating motor 11 is fixedly connected to the connecting shaft 12. The rotating motor 11 is started to rotate the output shaft of the rotating motor 11, so as to drive the connecting shaft 12 and the rotating plate 7 to rotate as a whole.

[0028] When in use, the RCO gas is introduced from the connecting pipe 2 on one side, then passes through the filter box 1, and is discharged through another connecting pipe 2. Two filtering operations are performed when passing through the filter box 1. After filtering for a period of time, the adjusting mechanism can be selected to drive the partition bar 4 and the four filter frames 5 to rotate ninety degrees as a whole, so that the unfiltered filter elements 6 on both sides are moved to the connecting pipes 2 on both sides without stopping the machine, and the filter element 6 to be replaced is moved to the gap between the filter box 1, the side baffle 8 and the two partition bars 4, separated from the filter channel, and then the filter frame 5 is taken out for replacement. After replacement, the above operation is repeated to perform the preparatory operation of replacing the filter element 6.
