Description

Technical Field

[0001] The utility model relates to the technical field of pyrolysis pretreatment, in particular to a pyrolysis pretreatment device for high-fluorine and high-chlorine hazardous waste. Background Art

[0002] High-fluorine and high-chlorine wastes generated during chemical production pose a serious threat to the environment and human health due to their high concentrations of fluorine and chlorine elements. They are also difficult to treat and have become one of the environmental problems that urgently need to be addressed in the chemical industry. Traditional treatment methods, such as direct incineration or landfilling, are not only inefficient but may also cause secondary pollution, such as the emission of harmful substances such as dioxins, which increases the environmental burden. In addition, these methods often ignore the potential resource value of waste, fail to achieve resource recycling, and are not in line with the concept of sustainable development. In recent years, pyrolysis pretreatment is a process that decomposes organic matter into smaller molecular compounds through high temperature under anaerobic or anoxic conditions. Compared with traditional treatment methods, pyrolysis pretreatment technology has the following advantages: Resource recovery: The gas, liquid and solid products produced during the pyrolysis process, such as synthesis gas, tar and carbon black, have high economic value and can be used for energy production or as chemical raw materials to realize waste resource utilization; Pollution control: Pyrolysis under anaerobic or anoxic conditions can effectively avoid the generation of harmful substances such as dioxins, thereby reducing the risk of secondary pollution; Treatment efficiency: Pyrolysis pretreatment technology can more thoroughly decompose organic matter in waste, improve treatment efficiency, reduce waste volume, and reduce subsequent treatment costs.

[0003] In the existing technology, during the use of pyrolysis pretreatment, it is impossible to quickly improve the preheating treatment efficiency and the quality of waste pyrolysis during the pyrolysis of high-fluorine and high-chlorine waste solutions; therefore, we have made improvements to this and proposed a high-fluorine and high-chlorine industrial hazardous waste pyrolysis pretreatment equipment. Utility Model Content

[0004] The purpose of the utility model is to address the problem that the current design of pyrolysis pretreatment cannot quickly improve the preheating treatment efficiency and the quality of waste pyrolysis during the pyrolysis process of high-fluorine and high-chlorine waste solutions.

[0005] In order to achieve the above-mentioned purpose of the utility model, the utility model provides the following technical solutions:

[0006] A pyrolysis pretreatment device for high-fluorine and high-chlorine hazardous waste is provided to improve the above problems.

[0007] The specific application is as follows:

[0008] A pyrolysis pretreatment device for highly fluorinated and highly chlorinated chemical hazardous waste, including a preheating processor. A treatment chamber is provided at the inner end of the preheating processor. A circulation pipe is provided at the inner end of the treatment chamber. A buoyancy plate is provided at the upper end of the circulation pipe. A first positioning seat and a second positioning seat are provided at the lower end of the buoyancy plate. A rotating shaft is provided at the inner end of the first positioning seat. A gear shaft is provided at the inner end of the second positioning seat. A linkage telescopic pipe is provided at the upper end of the gear shaft. The linkage telescopic pipe is embedded in the center of the circulation pipe. A gravity ring is provided at the tail end of the circulation pipe. A positioning ring and a linkage frame are provided between the circulation pipe and the linkage telescopic pipe.

[0009] As a preferred technical solution of the present application, the treatment chamber is embedded at the inner end of the preheating processor. The circulation pipe is fixed at the left end of the treatment chamber. The upper end of the circulation pipe is movably connected to the buoyancy plate.

[0010] As a preferred technical solution of the present application, the lower end of the buoyancy plate is fixedly connected to both the first positioning seat and the second positioning seat. The inner end of the first positioning seat is movably connected to the rotating shaft. The inner end of the second positioning seat is movably connected to the gear shaft.

[0011] As a preferred technical solution of the present application, the upper end of the rotating shaft is in contact with the outer surface of the circulation pipe. The upper end of the gear shaft is meshed with the linkage telescopic pipe. The linkage telescopic pipe is fixed at the inner end of the circulation pipe. The tail end of the circulation pipe is fixedly connected to the gravity ring.

[0012] As a preferred technical solution of the present application, the positioning ring is wrapped around the outer end of the circulation pipe. The outer end of the positioning ring is fixedly connected to the linkage frame.

[0013] As a preferred technical solution of the present application, a filter plate is provided at the lower end of the treatment chamber.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] In the solution of the present application:

[0016] The waste is pyrolytically pretreated through the treatment chamber in the preheating processor. By using the circulation pipe movably connected to the buoyancy plate and combining the linkage mechanism of the first positioning seat, rotating shaft, second positioning seat and gear shaft, automatic adjustment of the telescopic component in the circulation pipe is achieved to adapt to the change of liquid level height and optimize the fluid circulation efficiency. The combined use of the linkage telescopic pipe and the gravity ring ensures that the circulation pipe is stably oriented downward, facilitating the injection and circulation of fluid. The positioning ring and the linkage frame enhance the structural stability of the circulation pipe. The filter plate at the lower end of the treatment chamber further improves the purity of the pretreated waste and provides high-quality raw materials for the subsequent pyrolysis process. Through these key technical points, the whole system realizes the high efficiency, stability and safety of the pretreatment of highly fluorinated and highly chlorinated chemical hazardous waste, significantly improving the pretreatment efficiency and the quality of waste pyrolysis;

[0017] In addition, the buoyancy plate is designed to sense the change in the liquid level in the processing chamber. When the liquid level rises, the buoyancy plate rises accordingly, and vice versa. This automatic adjustment mechanism ensures that regardless of how the liquid level changes, the buoyancy plate always remains above the liquid level, thereby providing a reference signal for the adjustment of the telescopic pipe fitting.

[0018] Precise cooperation between the linkage telescopic pipe and the gear shaft: The meshing design between the telescopic pipe fitting and the gear shaft enables the rotation of the gear shaft to precisely control the telescopic movement of the telescopic pipe fitting. The rotation angle of the gear shaft is directly related to the lifting height of the buoyancy plate. Through precise transmission ratio design, it is ensured that the telescopic pipe fitting can achieve precise telescoping at different liquid levels to meet the requirements of liquid circulation.

[0019] Stabilizing effect of the gravity ring: The gravity ring design at the end of the circulation pipe not only provides additional weight to maintain the vertical stability of the circulation pipe, but also helps to maintain the correct direction and stable state of the telescopic pipe fitting at different liquid levels through its own weight and position, ensuring smoothness and efficiency during the fluid circulation process.

[0020] Structural support of the positioning ring and the linkage frame: The positioning ring is wrapped around the outer end of the circulation pipe and is fixedly connected to the linkage frame, jointly providing additional structural support for the circulation pipe, preventing the circulation pipe from shifting or deforming due to external forces during telescoping or liquid circulation, and ensuring the stable operation of the telescopic pipe fitting at any liquid level.
