Description

Technical Field

[0001] This invention relates to environmental protection technology and equipment, with a particular focus on the treatment of solid waste, specifically a method for the complete combustion of hazardous waste. Background Technology

[0002] Incineration in an incinerator is a common method for treating hazardous waste, but there are several issues that need to be addressed during the process: 1) Some solid waste contains iron impurities. During the incineration process, this iron is easy to form a molten state and solidify in the incinerator after being mixed with the combustion residue, affecting the capacity of the incinerator. At the same time, with continuous incineration operations, the volume of the solidified body continues to accumulate, affecting the service life of the incinerator and greatly shortening the maintenance interval. 2) During incineration, some of the hazardous waste materials entering the incinerator contain large-volume waste clumps, which are round in shape. When the diameter is greater than 3cm, these large-volume waste clumps require a long time to burn in order to achieve complete incineration treatment, resulting in some hazardous waste not being treated adequately.

[0003] Therefore, a method for the complete combustion treatment of hazardous waste is provided to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a method for the complete combustion treatment of hazardous waste.

[0005] The present invention achieves the above objectives through the following technical solutions: A method for complete combustion treatment of hazardous waste, comprising the following steps: 1) A hazardous waste material conveying module is installed, and a hazardous waste material weighing module is connected to the tail end of the hazardous waste material conveying module; 2) A material collection box is set below the hazardous waste material weighing module. The bottom plate of the material collection box is used as a material homogenization treatment carrier. An integrated material homogenization and analysis device is set above the material homogenization treatment carrier. The material homogenization treatment carrier is uniformly provided with leakage holes with a diameter of no more than 2cm. 4) A feeding hopper for the hazardous waste after homogenization and sorting is set below the material homogenization treatment carrier, and the feeding hopper for the hazardous waste after homogenization and sorting is connected to the feeding port of the incinerator; The integrated material homogenization and analysis device includes an overall downward driving cylinder, which is connected to a vertical lifting plate. A homogenization lifting cylinder is installed on the vertical lifting plate, and a lifting head is connected to the homogenization lifting cylinder. The lifting head is equipped with a vibrator and lifting pressure teeth, and a material homogenization pressure plate is installed on the vertical lifting plate. The lifting pressure teeth penetrate the material homogenization pressure plate. The material homogenizing plate includes a magnetic adsorption layer, and the material homogenizing plate is also evenly provided with several adsorption ports, which are connected to an external vacuum generating device through pipes. 5) Primary homogenization: After the material homogenization plate 46 presses the hazardous waste material or the material homogenization plate is 4cm away from the bottom plate of the material collection box, the lifting pressure teeth are driven to descend and extend through the material homogenization plate by 1-2cm. The vibrator performs vibration at a frequency of 15-25HZ for a time of not less than 10min. The lifting pressure teeth 45 homogenize the hazardous waste material and serve as the primary material homogenization actuator. 6) Secondary homogenization: The lifting pressure teeth are driven to descend and extend 3cm through the material homogenization pressure plate. The vibrator 44 performs vibration at a frequency of 20-30HZ for 15min. The lifting pressure teeth homogenize the hazardous waste material and are used as the secondary material homogenization actuator. 7) Material sorting: The adsorption port of the material homogenization plate is connected to an external vacuum generator through a pipeline to perform adsorption, adsorbing large-volume hazardous waste that cannot be discharged through the leakage hole; simultaneously, the magnetic adsorption layer adsorbs iron impurities in the hazardous waste, serving as a material sorting actuator. 8) Complete combustion of hazardous waste that has undergone diameter screening to remove iron impurities.

[0006] Furthermore, the hazardous waste material conveying module is composed of a conveyor belt module, and the surface of the conveyor belt of the conveyor belt module is covered with a polyethylene film.

[0007] Furthermore, the hazardous waste material weighing module includes a weighing module housing, the bottom of which is an openable and closable weighing module base plate. A weight sensor is installed on the weighing module base plate, and the weighing module base plate is connected to a weighing module base plate opening and closing drive hydraulic cylinder installed on the weighing module housing.

[0008] Furthermore, the inner wall of the material collection box corresponding to the hazardous waste material weighing module has a slope A, which serves as a downward-sloping material collection plate.

[0009] Furthermore, A is 45-60°.

[0010] Furthermore, the material homogenization treatment carrier is connected to the material collection box and a hydraulic cylinder for opening and closing after material homogenization is installed.

[0011] Furthermore, one side of the hazardous waste feeding hopper is a feeding and collection plate with a slope B.

[0012] Furthermore, B is 15-30°.

[0013] Compared with existing technologies, this invention effectively ensures that no waste clumps larger than 2cm are present in the hazardous waste entering the incinerator through material homogenization and sorting. At the same time, it also sorts and removes iron impurities in the hazardous waste, effectively preventing iron impurities from entering the incinerator and ensuring that the incineration of hazardous waste is carried out fully and with high quality.
