Description

Technical Field

[0001] This invention relates to the field of waste gas concentration equipment technology, and more specifically, to a high-concentration-ratio, high-temperature resistant, lightweight organic waste gas concentration equipment. Background Technology

[0002] With increasingly stringent industrial waste gas emission standards in my country and globally, the treatment of volatile organic compounds (VOCs) has become an environmental challenge that industries such as chemical, coating, printing, electronics, and pharmaceuticals must address. Among numerous VOC treatment technologies, the combined adsorption concentration and high-temperature oxidation process is widely used due to its high treatment efficiency and relatively low operating costs. The core component of this process is the concentration unit, which adsorbs and enriches large volumes of low-concentration organic waste gas, transforming it into small volumes of high-concentration gas, thereby significantly reducing the size and energy consumption of subsequent oxidation treatment equipment.

[0003] Adsorption is the current mainstream concentration technology. Its core principle is to selectively adsorb volatile organic compounds using an adsorbent. In existing adsorption methods, air is blown through a simple filter to the adsorption mechanism by a fan and transported by a pipeline. However, simple pipeline transport cannot effectively adjust the air flow. During desorption, hot air is blown directly onto the adsorbate, resulting in excessively scattered hot air and failure to produce uniform desorption. To solve these problems, this application proposes a novel high-concentration-ratio, high-temperature resistant, lightweight organic waste gas concentration device. Summary of the Invention

[0004] The purpose of this invention is to provide a high-concentration-ratio, high-temperature resistant, lightweight organic waste gas concentration device to solve the problems mentioned in the background art: ensuring that the airflow is evenly distributed to each area of ​​the adsorption unit, avoiding the decrease in concentration ratio caused by local overload, making filter replacement more convenient, and improving the desorption effect of the adsorption ring.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A high-concentration-ratio, high-temperature resistant, lightweight organic waste gas concentration device includes:

[0007] The air intake mechanism includes a straight cylindrical shell, an annular plate, and multiple rotating rods. An outer ring is fitted on the end face of the straight cylindrical shell. Each of the multiple rotating rods is connected to a guide vane. Each of the multiple rotating rods is connected to a first swing plate. Multiple first vertical rods are provided on the end face of the annular plate.

[0008] The preliminary filtration mechanism includes a housing, three embedded shells and a ridge; each of the three embedded shells is equipped with four filter screens; the ridge is connected to a top plate;

[0009] The adsorption mechanism includes an adsorption shell, a ring sleeve, a rotating shaft, and an arc plate. Multiple adsorption rings are sleeved on the end face of the rotating shaft. A placement groove is opened on the end face of the arc plate. A movable plate is set inside the placement groove. Multiple conical plates are connected to the end face of the movable plate. Multiple flipping rods are set on the end faces of the multiple conical plates. A second swing plate is connected to the end face of the movable plate. An inner disk is set inside the ring sleeve. The rotating shell is connected to the inner disk. Multiple fan blades are set on the end face of the rotating shell.

[0010] By adopting the above technical solution, the airflow is evenly distributed to each area of ​​the adsorption unit through the guide vanes, avoiding the decrease in concentration ratio caused by local overload;

[0011] The use of the protrusions and the top plate facilitates the replacement of the embedded shell;

[0012] The rotating inner disc facilitates the even blowing of hot air, and the cone plate and the flipping rod work together to sweep across the adsorption ring, increasing the desorption effect.

[0013] Preferably, it also includes a base plate, a preliminary filtration mechanism connected to a sinking air casing, a cooler installed on the end face of the sinking air casing, an adsorption mechanism connected to an air outlet casing, a partition installed on the end face of the base plate, a heating box installed on the end face of the base plate, and a high-temperature box installed on the end face of the base plate.

[0014] By adopting the above technical solution, air is supplied by the air intake mechanism to the preliminary filtration mechanism, which filters out large particles in the air. The air passes through the sinking air shell to the adsorption mechanism, where it is processed. After desorption, the adsorption mechanism is cooled by a cold air blower for reuse. Moreover, the desorption process requires heating from a heating box, and the high-concentration waste gas desorbed enters the high-temperature box for high-temperature purification.

[0015] Preferably, a horn shell is connected to the end face of the straight shell, four first guide plates are provided on the inner wall of the horn shell, six second guide plates are provided on the inner wall of the straight shell, and an initial fan is connected to the end face of the straight shell.

[0016] By adopting the above technical solution, the initial fan can draw air into the straight cylindrical shell. The air passes through the guide vanes and is guided evenly by the second guide plate to reach the horn shell. Then, it is drawn by the first guide plate and stably enters the preliminary filtration mechanism.

[0017] Preferably, the outer end face is provided with an annular groove, the inner wall of the annular groove is provided with multiple holes, and the holes penetrate the straight cylindrical shell. Each of the multiple holes is provided with a support cylinder, multiple rotating rods are provided on the inner wall of the multiple support cylinders, multiple first swing plates are respectively connected to multiple first vertical rods, and a sealing plate is provided inside the annular groove.

[0018] By adopting the above technical solution, the support cylinder can stably install the rotating rod inside the hole. The ring plate will drive the first swing plate to swing through the first vertical rod. The swinging first swing plate will drive the rotating rod to rotate, thereby driving the guide vane to rotate. Moreover, these structures are sealed inside the ring groove by the sealing plate to prevent external factors from affecting the normal use of the structure.

[0020] By adopting the above technical solution, the motor inside the annular groove will drive the gear to rotate, and the rotating gear will drive the annular plate to rotate through the toothed plate. The annular plate is supported by the rollers between the support plates, so that the annular plate can be stably driven by the first vertical rod to move the first swing plate.

[0021] Preferably, the end face of the housing is provided with two side blocks, the inner wall of each side block is provided with two baffles, the three embedded end faces are provided with multiple transverse grooves, and the end face of the protrusion is connected to a rotating block.

[0022] By adopting the above technical solution, air enters the embedded shell from the horizontal groove and reaches the position of the filter screen. The filter screen filters large particles in the air. Moreover, the rotating block can drive the convex strip to rotate, which facilitates the fixation of the filter screen. In addition, the stop bar on the rotating side block can block the outer end of the embedded shell to prevent the embedded block from falling out of the shell.

[0023] Preferably, each of the three embedded shells has a side plate fixedly installed on its inner wall, each of the three embedded shells has an inner groove, the three top plates are respectively installed inside the three inner grooves, and the three protrusions are respectively installed inside the three inner grooves.

[0024] By adopting the above technical solution, when installing the filter screen, first insert the filter screen into the embedded shell, insert one end of the filter screen into the inner wall of the side plate, and the other end is driven by the rotating convex strip to tighten and fix the top plate.

[0025] Preferably, the inner wall of the adsorption shell is provided with two support frames, and the inner wall of each support frame is provided with two fan plates. Two of the four fan plates are connected to two hot air pipes, and the other two of the four fan plates are connected to two cold air pipes. Magnetic levitation bearings are provided inside the two support frames, and the rotating shaft is located between the two magnetic levitation bearings.

[0026] By adopting the above technical solution, the magnetic levitation bearing reduces the resistance to the rotation of the shaft. Moreover, the magnetic levitation bearing is supported by a support frame, and the fan plate can separate the cold air and hot air zones. Furthermore, air at different temperatures is output through the hot air pipe and the cold air pipe, which facilitates desorption and allows the adsorption ring to quickly enter the working state.

[0027] Preferably, the inner wall of the adsorption shell has a top groove, the arc plate is disposed inside the top groove, the end face of the arc plate has multiple swing grooves, and multiple cone plates are disposed inside the multiple swing grooves respectively.

[0028] By adopting the above technical solution, the cone plate will move inside the swing groove, allowing the cone plate to stroke the adsorption ring, thereby improving the desorption effect of the adsorption ring.

[0029] Preferably, the rotating shell end face has multiple air inlets, the inner plate end face has multiple air outlets, the inner plate end face is provided with a second vertical rod, the second swing plate and the second vertical rod are connected and arranged, and the ring is sleeved on the inner wall of one of the two hot air pipes.

[0030] By adopting the above technical solution, when hot air is blown from the hot air pipe to the rotating shell, the air will enter the inner plate through the air inlet and eventually be discharged from the air outlet. Moreover, the seal will drive the inner plate to rotate, which will drive the second swing plate to swing through the second vertical rod, thereby controlling the use of the cone plate.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] 1) When this waste gas concentration device is in use, the rotating ring plate drives the first swing plate to swing through the first vertical rod. The rotating rod will drive the guide vanes to rotate inside the straight cylinder shell, thereby changing the angle of the guide vanes inside the straight cylinder shell. This facilitates the flow guidance under different conditions, ensuring that the airflow is evenly distributed to each area of ​​the adsorption unit and avoiding a decrease in the concentration ratio caused by local overload.

[0033] 2) When using this waste gas concentration device, the filter screen can be removed from the embedded shell by pulling out the embedded shell inside the housing and rotating the convex strip to loosen the pushing action on the top plate. After installing the new filter screen, rotate the convex strip again, and the convex strip will push the top plate, while the top plate presses on the filter screen to fix the filter screen, making it easier to replace the filter screen.

[0034] 3) When this waste gas concentration device is in use, when hot air blows towards the rotating shell, the fan blades on the rotating shell will drive the rotating shell to rotate. The rotating shell will drive the inner disc to rotate inside the ring, allowing the inner disc to drive the second swing plate to swing, thereby driving the cone plate below the moving plate to move between the adsorption rings. The flipping rod will move the adsorption rings, making the desorption effect of the adsorption rings better. Moreover, the rotating inner disc makes the hot air blowing more even, further improving the desorption effect. Attached Figure Description

The second vertical rod 520 is fixedly disposed on the rear end face of the inner plate 518. The second vertical rod 520 is slidably disposed on the inner wall of the second swing plate 513. The ring sleeve 519 is fixedly disposed on the inner wall of the short hot air pipe 502. The short pipe of the hot air pipe 502, one of the cold air pipes 503 and the heating box 8 are connected. The long pipe of the hot air pipe 502 is connected to the high temperature box 10. The other cold air pipe 503 is connected to the air cooler 4. The adsorption ring 507 is made of corrugated ceramic fiber paper.

[0062] The steps of using this invention are as follows: The filtered air enters from below the adsorption mechanism 5. An external motor installed in the sinking air housing 3 drives the rotating shaft 506 to rotate. The rotating shaft 506 drives the adsorption disc to rotate, adsorbing the waste gas in the air. The purified air is discharged from the lower rear side of the adsorption housing 501. The adsorption ring 507, which adsorbs the waste gas, rotates to the top of the adsorption housing 501. The cool air blower 4 blows air to the heating box 8 through the cool air pipe 503. The heating box 8 heats the air, and the heated air enters the hot air pipe 502 and blows towards the rotating housing 515. When the air blows the fan blades 517, it causes the rotating housing 515 to rotate. The rotating housing 515 causes the inner disc 518 to rotate inside the ring 519. Hot air enters the inner disk 518 through the air inlet 516 and then exits through the air outlet 523, blowing towards the adsorption ring 507 and carrying the exhaust gas out through the long hot air pipe 502. The rotating inner disk 518 drives the second swing plate 513 to swing via the second vertical rod 520. The second swing plate 513 causes the moving plate 511 to move inside the placement slot 512. The moving plate 511 drives the cone plate 521 to move between the two adsorption rings 507. The flipping rod 522 on the cone plate 521 slides over the adsorption ring 507, improving the desorption effect of the exhaust gas. After desorption, the adsorption ring 507 reaches the position of the cold air pipe 503 and is quickly cooled down by the cold air, making it convenient for the next use.
