Description

Technical Field

[0001] This utility model relates to the field of pyrolysis gas recovery technology, specifically to a black powder anti-clogging mechanism. Background Technology

[0002] In the recycling of waste household appliances or lithium batteries, the pyrolysis gas in the pyrolysis furnace will produce black powder, which is mainly composed of black or dark-colored powdery solid impurities such as carbonaceous particles, heavy polymer residues, and metal oxide dust. Current technology uses a flame-retardant filter to filter the black powder from the pyrolysis gas; however, in actual production, the flame-retardant filter frequently becomes clogged and typically needs to be disassembled and cleaned every few days. This cleaning process requires a cooling time of more than eight hours, severely reducing production efficiency. Utility Model Content

[0003] In view of the above-mentioned problems in the prior art, the present invention provides a black powder anti-clogging mechanism, which solves the problem that the prior art is prone to clogging due to the use of a single flame-retardant filter to filter black powder.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0005] A black powder anti-clogging mechanism is provided, including an air inlet pipe connected to a pyrolysis furnace, the air inlet pipe being connected to an exhaust pipe via a parallel pipeline; the parallel pipeline includes at least two parallel gas pipes, each gas pipe having a flame-retardant filter detachably installed in the middle, and each gas pipe having a valve installed near the air inlet pipe and the exhaust pipe.

[0006] The beneficial effects of this solution are as follows: By connecting at least two flame-retardant filters between the intake and exhaust pipes through parallel piping, and with valves on each gas pipe, the appropriate flame-retardant filter can be activated as needed. Therefore, even if a flame-retardant filter becomes clogged during production, other unclogged flame-retardant filters can be immediately switched to filter the black powder via valves, without affecting production efficiency. After switching, the clogged flame-retardant filter can be disassembled for cleaning and reconnected to the gas pipeline without disrupting production. Compared to existing technologies using a single flame-retardant filter, the parallel piping and the combination of at least two flame-retardant filters reduce the risk of complete clogging of the entire filtration system, ensuring production efficiency.

[0007] Furthermore, each flame-retardant filter is equipped with connecting pipes at both ends, and each connecting pipe is connected to the gas pipeline via a flange. The flange connection structure facilitates the quick assembly and disassembly of the flame-retardant filter.

[0008] Furthermore, each gas pipeline is equipped with a pressure sensor and a flow sensor at the inlet and outlet ends near the flame-retardant filter, respectively. The pressure sensor's readings help determine which gas pipeline is connected to the pyrolysis gas, while the flow sensor's readings help determine whether the flame-retardant filter in the pyrolysis gas pipeline is clogged.

[0009] Furthermore, each valve is a solenoid valve, and each solenoid valve, each pressure sensor, and each gas flow sensor are electrically connected to the controller. The controller, solenoid valves, pressure sensors, and gas flow sensors form a control system. The controller can control the opening and closing of the solenoid valves based on the data from the pressure sensors and gas flow sensors. It can automatically switch the gas pipeline after detecting that the flame-retardant filter is clogged, thus avoiding manual control.

[0010] Furthermore, the controller is electrically connected to the alarm. The alarm can promptly alert workers when a blockage occurs, reminding them to disassemble and clean the clogged flame-retardant filter.

[0011] Furthermore, the parallel piping also includes a branch pipe and a manifold that are connected to both ends of each gas pipe, respectively. The branch pipe and the manifold are connected to the intake pipe and the exhaust pipe, respectively. The installation of the branch pipe and the manifold facilitates the optimization of the piping layout.

[0012] Furthermore, both the branch pipe and the manifold are T-type tees.

[0013] Furthermore, each flame-retardant filter element has a honeycomb structure. The alternating hexagonal channels within the honeycomb filter element guide gas flow, preventing localized particle accumulation caused by turbulence, thus reducing the risk of clogging compared to traditional random fiber filter elements.

[0014] Furthermore, all flame-retardant filters are arranged in a straight line. This straight-line arrangement facilitates consistent maintenance.

[0015] Furthermore, the controller is a PLC. Compared to microcontrollers, PLCs are better able to meet the high reliability requirements of industrial scenarios. Attached Figure Description

[0018] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.

[0019] This embodiment provides a black powder anti-clogging mechanism, which is used to solve the problem of easy clogging caused by the existing technology of filtering black powder through a single flame-retardant filter. It is shown in detail below.

[0020] refer to Figure 1 The black powder anti-clogging mechanism of this scheme includes an air inlet pipe 1, a parallel pipeline, and an exhaust pipe 3. One end of the air inlet pipe 1 is connected to the pyrolysis furnace, and the other end of the air inlet pipe 1 is connected to the exhaust pipe 3 through the parallel pipeline.

[0021] The parallel pipeline includes at least two parallel gas pipes 2, each gas pipe 2 has a flame-retardant filter 4 that can be detachably installed in the middle, and each gas pipe 2 has a valve 21 installed near the air inlet pipe 1 and the exhaust pipe 3.

[0022] Preferably, there are two air pipes 2. The intake pipe 1 and the exhaust pipe 3 are respectively connected to the middle of the branch pipe 24 and the manifold 25. Both the branch pipe 24 and the manifold 25 are T-shaped tee pipes. The two ends of the branch pipe 24 and the manifold 25 are respectively connected to the two air pipes 2.

[0023] In this embodiment, each flame-retardant filter 4 is provided with a connecting pipe 41 at both ends, and each connecting pipe 41 is connected to the gas pipeline 2 through a flange 42. The flange 42 connection structure facilitates the quick assembly and disassembly of the flame-retardant filter 4.

[0024] As a further aspect of this embodiment, for ease of maintenance, all flame-retardant filters 4 are arranged in the same straight line. Simultaneously, to reduce the risk of clogging for each flame-retardant filter 4, the filter element of each flame-retardant filter 4 has a honeycomb structure. The alternating hexagonal channels within the honeycomb filter element guide gas flow, preventing localized particle accumulation caused by turbulence, thus reducing the risk of clogging compared to traditional random fiber filter elements.

[0025] As a further embodiment, each gas pipe 2 is equipped with a pressure sensor 22 and a gas flow sensor 23 at the inlet and outlet ends near the flame-retardant filter 4, respectively. Both the pressure sensor 22 and the gas flow sensor 23 can be sensors with digital displays for easy viewing by workers. The pressure reading from the pressure sensor 22 helps determine the gas pipe 2 connected to the pyrolysis gas, while the flow rate from the gas flow sensor 23 helps determine whether the flame-retardant filter 4 in the pyrolysis gas pipe 2 is blocked.

[0026] In this embodiment, all valves 21 can be manual valves 21, and the pipeline can be switched by workers manually closing or opening the two valves 21 on the gas pipeline 2.

[0027] As another embodiment, to achieve automatic switching of gas pipeline 2, each valve 21 is a solenoid valve, and each solenoid valve, each pressure sensor 22, and each gas flow sensor 23 are electrically connected to the controller. The controller, solenoid valves, pressure sensors 22, and gas flow sensors 23 form a control system. The controller can determine whether the operating gas pipeline 2 is blocked by comparing the data from the pressure sensors 22 and gas flow sensors 23 with the corresponding set thresholds. At the same time, after the flame-retardant filter 4 is blocked, the controller can automatically switch gas pipeline 2 by controlling the opening and closing of all solenoid valves.

[0028] The controller can be a PLC. Compared to a microcontroller, a PLC can better meet the high reliability requirements of industrial scenarios. Additionally, to remind workers to disassemble and clean the clogged flame-retardant filter 4, the controller is electrically connected to an alarm, which can provide timely warnings when a blockage occurs.

[0029] In summary, the beneficial effects of this plan are as follows:

[0030] By connecting at least two flame-retardant filters 4 between the intake pipe 1 and the exhaust pipe 3 via parallel piping, and coordinating with valves 21 on each air pipe 2, the corresponding flame-retardant filter 4 can be activated as needed. Therefore, even if a flame-retardant filter 4 becomes clogged during production, other unclogged flame-retardant filters 4 can be immediately switched via valves 21 to filter the black powder, without affecting production efficiency. After switching, the clogged flame-retardant filter 4 can be disassembled for cleaning and reconnected to the air pipe 2 without disrupting production. Compared to the single flame-retardant filter 4 in existing technologies, the parallel piping and the combination of at least two flame-retardant filters 4 reduce the risk of complete clogging of the entire filtration system, ensuring production efficiency.

[0031] Although the specific embodiments of the utility model have been described in detail with reference to the accompanying drawings, this should not be construed as limiting the scope of protection of this patent. Various modifications and variations that can be made by those skilled in the art without inventive effort within the scope described in the claims still fall within the scope of protection of this patent.
