Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment equipment, in particular to an exhaust gas adsorption device capable of on-line detection. Background Technique

[0002] Waste gas refers to the toxic and harmful gases discharged by humans in the process of production and life. Especially in chemical plants, steel plants, pharmaceutical factories, coking plants and oil refineries, etc., the discharged waste gas has a strong smell, seriously pollutes the environment and affects human health. In order to make the waste gas meet the emission standards, it is necessary to use adsorption equipment to absorb the harmful substances in the waste gas. The adsorption capacity of the adsorption component is limited, and it cannot perform the adsorption work after reaching the adsorption limit. Existing equipment usually has a remote monitoring function to ensure that it can be quickly discovered after the adsorption component is saturated. However, these devices can only give reminders and warnings after detecting that the adsorption component is saturated, and cannot replace the adsorption material in time. Content of the Utility Model

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the present utility model provides an exhaust gas adsorption device capable of on-line detection, having the following beneficial effects:

[0015] 1. By providing a chute and a locking member, before installation, two frames and adsorption plates are placed in the chute. The lower frame and adsorption plate are aligned with the connecting pipe and adsorption work is carried out. When the adsorption plate is saturated, the exhaust gas cannot pass through, the air pressure on the front side of the adsorption plate increases, and the air pressure on the back side decreases. When the air pressure detection component detects that the pressure difference reaches the set value, a signal is sent through the remote control terminal, and at the same time, the locking member is controlled to open. The locking member releases the restriction on the frame, so that the frame drives the adsorption plate to slide down, and at the same time, the upper frame drives a new adsorption plate to slide down to align with the connecting pipe and is fixed by the locking member inside, achieving the purpose of timely replacing the adsorption plate.

[0016] 2. By providing a closed cover and a cover plate, the closed cover can protect the adsorption plate to be replaced, prevent it from contacting the air, and prevent dust in the air from falling on the adsorption plate, resulting in the performance of the adsorption plate being affected. The cover plate can open or close the closed cover. When it is closed, it can completely seal the closed cover. When it is opened, it is convenient to place a new frame and adsorption plate in the closed cover and the chute. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation manner

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , an exhaust gas adsorption device that can be detected online, including a connecting pipe 1. Connecting plates 8 are provided at both ends of the connecting pipe 1. The connecting plates 8 are used to connect with the exhaust gas pipeline. Chutes 5 are provided on both sides in the middle of the connecting pipe 1. The chutes 5 penetrate the connecting pipe 1. Two frames 12 are slidably connected in the chutes 5. Adsorption plates 9 are provided in both of the two frames 12, and the positions of the lower frame 12 and the adsorption plate 9 are aligned with the connecting pipe 1. Fixing grooves 13 are provided on the side surfaces of the frames 12. Locking components 4 are provided at positions corresponding to the fixing grooves 13 on the side surfaces of the chutes 5. The locking components 4 are inserted into the fixing grooves 13. A remote control terminal 3 is provided outside the chutes 5. Air pressure detectors 2 are provided on both sides of the remote control terminal 3. The air pressure detectors 2 are located on both sides of the adsorption plate 9;

[0024] In the present invention, the chute 5 and the locking component 4 are provided. The chute 5 can limit and store the adsorption plate 9 through the frame 12. On the one hand, it enables the frame 12 to drive the adsorption plate 9 to be aligned with the connecting pipe 1 for adsorption work. On the other hand, it stores a brand-new frame 12 and adsorption plate 9, and automatically slides down to make up the position after the lower frame 12 and the adsorption plate 9 fall off, achieving the purpose of rapid automatic replacement, and the locking component 4 can control the fixation and detachment of the frame 12.

[0025] The locking component 4 includes a solenoid valve 401, a locking rod 402, and a first spring 403. The solenoid valve 401 is provided outside the chute 5. The locking rod 402 is connected to the solenoid valve 401 and is inserted into the fixing groove 13. The first spring 403 is provided outside the locking rod 402 and applies an elastic force to the locking rod 402 to move it into the fixing groove 13;

[0026] By setting the first spring 403, the first spring 403 uses its own elastic force to push the locking rod 402 into the fixing groove 13, so that the locking component 4 is in the locked state under normal conditions. Only when the solenoid valve 401 drives the locking rod 402 to open under the energized state. In this way, it can be avoided that in the case of accidental power failure, the locking component 4 is accidentally opened, resulting in the separation of the frame 12 and the adsorption plate 9.

[0027] At the position where the top of the connecting pipe 1 is located on the side of the sliding groove 5, there is a closed cover 10. The closed cover 10 is used to store the frame 12 and the adsorption plate 9. The top end of the closed cover 10 is slidably connected with a cover plate 11, and the cover plate 11 is used to open or close the closed cover 10;

[0028] By setting the closed cover 10, the closed cover 10 can protect the frame 12 and the adsorption plate 9 to be replaced, avoiding the contact of the adsorption plate 9 to be replaced with air, resulting in the attachment of impurities such as dust in the air to the adsorption plate 9, leading to the problem of reduced working performance of the adsorption plate 9.

[0029] Below the sliding groove 5, there is a buffer component 7. The buffer component 7 is used to receive and buffer the falling frame 12 and adsorption plate 9. The buffer component 7 includes a sliding rod 701, a second spring 702 and a support plate 703. The sliding rod 701 is slidably connected with the sliding groove 5. The second spring 702 is arranged on the side of the sliding rod 701 and applies an upward pulling force to the sliding rod 701. The support plate 703 is arranged at the bottom end of the sliding rod 701;

[0030] By setting the second spring 702 and the sliding rod 701, when the frame 12 drives the adsorption plate 9 to fall off along the sliding groove 5, the frame 12 will be carried by the support plate 703. The falling force of the frame 12 and the adsorption plate 9 will act on the sliding rod 701, causing the sliding rod 701 to slide downward. The sliding rod 701 uses the second spring 702 to absorb the downward impact force, so that the frame 12 and the adsorption plate 9 are firmly fixed, which is convenient for subsequent centralized treatment of the used adsorption plate 9.

[0031] On the outside of the sliding groove 5, near the position of the buffer component 7, there is an indicator light 6. The indicator light 6 will be turned on after the buffer component 7 works;

[0032] By setting the indicator light 6, after the buffer component 7 is triggered, the indicator light 6 will correspondingly light up, indicating that the adsorption plate 9 has been replaced at this time, and the used adsorption plate 9 has been automatically discharged, prompting the staff to collect the used adsorption plate 9 in time and replenish a new adsorption plate 9.

[0033] Working principle:

[0034] The border 12 to be replaced and the adsorption plate 9 are placed in advance in the closed cover 10. After the adsorption plate 9 in the connecting pipe 1 is protected, the waste gas cannot pass through the adsorption plate 9, resulting in different air pressure differences on both sides of the adsorption plate 9. After the air pressure detector 2 detects that the difference reaches the set value, it sends a signal through the remote control terminal 3 and controls the solenoid valve 401 to work. The solenoid valve 401 causes the locking rod 402 to move out of the fixed slot 13, releasing the fixation of the border 12. The border 12 slides along the chute 5, and the waste adsorption plate 9 drops downward and is received by the buffer member 7. At the same time, the border 12 and the adsorption plate 9 in the closed cover 10 lose support, slide downward, align with the connecting pipe 1, and are then locked by the locking member 4, completing the automatic replacement of the adsorption plate 9.

[0035] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements, or modifications made based on the present invention to solve substantially the same technical problems and achieve substantially the same technical effects are all covered by the protection scope of the present invention.
