Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically to a modular dual-rotor NMP waste gas treatment unit. Background Technology

[0002] The modular dual-rotor NMP exhaust gas treatment unit is an advanced purification device specifically designed for treating exhaust gas containing N-methylpyrrolidone (NMP). It adopts dual-rotor adsorption and concentration technology, combined with a modular design concept, and has the advantages of high efficiency, energy saving, and flexibility.

[0003] Patent specification CN109395533A discloses a modular waste gas treatment device, comprising a horizontally arranged, linearly connected, detachable modular structure, and interconnected by pipelines, consisting of a filtration module, an adsorption module, a distribution module, a heat storage module, a combustion module, and a heat exchange module. Each of these modules includes a cubic chamber with internal functional components of equal cross-section. The filtration module contains a filter bag, the adsorption module contains a concentrator impeller, the distribution module contains a rotary distribution valve, the heat storage module contains a ceramic heat storage element, and the combustion module contains a burner. This invention employs a modular integrated design, reducing the overall heat dissipation area of ​​the equipment, significantly shortening the length of various pipelines, resulting in significant energy savings, reduced manufacturing costs, and simplified on-site transportation and installation.

[0004] While the aforementioned technical solutions reduce the overall heat dissipation area of ​​the equipment, the impeller needs to rotate for extended periods, requiring regular maintenance and even repairs. In practice, maintaining the impeller in these solutions is cumbersome and inconvenient for replacement. Therefore, we propose a modular dual-impeller NMP exhaust gas treatment unit. Utility Model Content

[0005] This invention provides a modular dual-rotor NMP exhaust gas treatment unit that solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] An embodiment of this utility model provides a modular dual-rotor NMP exhaust gas treatment unit, comprising:

[0008] Adsorption box;

[0009] The rotary box is fixedly connected to one end of the adsorption box to realize the adsorption, desorption, and concentration of waste gas;

[0010] A connecting box is located at one end of the rotary wheel box to connect the absorption filter cartridge and the rotary wheel box;

[0011] The absorption filter cartridge is fixedly connected to one end of the connecting box to achieve the filtration and absorption of exhaust gas;

[0012] The drive motor is fixedly installed inside the wheel box to drive the adsorption wheel to rotate;

[0013] The connecting column is fixedly connected to the output end of the drive motor, enabling the adsorption wheel to rotate.

[0014] The adsorption rotor is rotatably installed at both ends inside the rotor box to achieve adsorption, desorption, and concentration of waste gas.

[0015] The disassembly and assembly device is located at one end of the rotary box and is used to disassemble and assemble the rotary box and the connecting box.

[0016] A mobile device is installed on the surface of the rotary box and the adsorption box to achieve the separation and connection of the rotary box and the connecting box.

[0017] Furthermore, the disassembly and assembly device includes a storage slot, which is located at one end of the connecting box. A connecting seat is provided inside the storage slot. Sliding plates are slidably installed at both ends inside the connecting seat. Positioning seats are fixedly installed on the surfaces of the two sliding plates.

A connecting rod is fixedly connected to one end of each of the two threaded rods. A dual-axis motor is provided inside the connecting seat.

[0018] The above technical solution utilizes a storage slot to house the connecting seat, allowing the rotary box and the connecting box to be joined. A dual-axis motor then drives the connecting rod and threaded rod to rotate, causing the threaded rod to move the threaded sliding and positioning seats, which then enter the positioning slot. This completes the assembly and fixing of the rotary box and the connecting box, effectively improving the efficiency of disassembly and installation. It also facilitates the inspection, replacement, and maintenance of the adsorption wheels inside the rotary box, increasing the device's working efficiency and making it easier for staff to maintain and service the device.

[0019] Furthermore, the connecting seat is movably installed with the communicating box, one end of the positioning seat extends into the interior of the positioning groove, and the positioning seat is movably installed with the communicating box.

[0020] By using the above technical solution, one end of the positioning seat extends into the interior of the positioning groove, allowing the positioning seat to enter the interior of the positioning groove or be pulled out of the positioning groove, thereby achieving the disassembly and assembly of the rotary box and the connecting box.

[0021] Furthermore, the positioning seat and the connecting seat are slidably installed, the connecting rod is fixedly connected to the output end of the dual-axis motor, a support seat is fixedly installed on the surface of the dual-axis motor, and the support seat is fixedly installed inside the connecting seat.

[0022] Through the above technical solution, by fixing the support base and connecting base and the dual-axis motor, the dual-axis motor can be positioned, thereby achieving the effect of the dual-axis motor driving the connecting rod to rotate.

[0023] Furthermore, a sliding rod is slidably installed on the other side of both sliding plates. The sliding rod is fixedly installed inside the connecting seat. An exhaust pipe is fixedly connected to the upper end of the absorption filter cylinder, and an exhaust gas pipe is fixedly connected to the other end of the adsorption box.

[0024] Through the above technical solution, the sliding plate is slidably installed with the sliding rod, making the movement of the sliding plate more stable. The exhaust pipe discharges the filtered and absorbed waste gas to the outside. The waste gas pipe introduces the generated waste gas into the adsorption box, where the activated carbon plate in the adsorption box performs the first step of adsorption treatment on the waste gas.

[0025] Furthermore, the mobile device includes a support plate, which is fixedly installed on the lower surface of the rotary box and the adsorption box. A connecting plate is fixedly installed at one end of the support plate, and a cylinder is fixedly connected to the surface of the connecting plate. A base plate is fixedly installed at the bottom end of the cylinder.

[0026] Through the above technical solution, the cylinder can drive the connecting plate and the support plate to move, thereby moving the wheel box away from the connecting box, which ultimately makes it easier for staff to repair and maintain the adsorption wheel inside the wheel box.

[0027] Furthermore, a base is fixedly installed on the lower surface of the base plate, a groove is formed on the upper surface of the base, and a movable wheel is provided on the lower surface of the support plate, with the movable wheel located inside the groove.

[0028] The above technical solution facilitates the movement of the support plate through the coordinated action of the movable wheels and the sliding groove.

[0029] Furthermore, a support frame is fixedly installed on the lower surface of both the connecting box and the absorption filter cartridge, and the support frame is fixedly connected to the base.

[0030] The above technical solution uses a support frame to elevate the connecting box and the absorption filter cartridge to the same height as the adsorption box, facilitating docking and separation between the adsorption box and the connecting box.

[0031] The above-described solution of this utility model has at least the following beneficial effects:

[0032] 1. This utility model uses a dual-axis motor to drive the connecting rod and the threaded rod to rotate, which in turn moves the threaded rod and the sliding and positioning seats that are threadedly installed with it. This allows the positioning seats to enter the positioning groove, thus completing the assembly and fixing of the wheel box and the connecting box. This effectively improves the efficiency of disassembling and installing the wheel box, and facilitates the inspection, replacement and maintenance of the adsorption wheel inside the wheel box. This improves the working efficiency of the device and also makes it easier for staff to maintain and repair the device.

[0033] 2. In this utility model, the cylinder can drive the connecting plate and the support plate to move, thereby moving the wheel box away from the connecting box, which ultimately makes it easier for staff to repair and maintain the adsorption wheel inside the wheel box.
