Hazardous waste pretreatment mixing equipment and treatment method thereof

Abstract

The invention discloses hazardous waste pretreatment mixing equipment and a treatment method thereof. The mixing equipment includes a double-screw stirring device, wherein a uniform feeding mechanismfor ensuring synchronous and uniform stirring of all materials so as to effectively control the stirring efficiency is fixed at the top of the double-screw stirring device. The hazardous waste pretreatment mixing equipment and the treatment method thereof are different from the prior art, wherein in the real-time pretreatment and mixing process of hazardous wastes, the continuous, stable and uniform scattering of the materials can be ensured; effective diffusion of the hazardous waste materials before premixing and stirring is ensured; after the materials enter the stirring equipment, the stirring time of the materials at each stirring position is the same, and the synchronous stirring of the materials at each position is ensured, so that the stirring uniformity of the hazardous waste materials in a relatively fixed time period is ensured, and the premixing treatment efficiency of the hazardous waste materials is effectively improved.

Description

technical field [0001] The invention relates to the technical field of mixing equipment, in particular to hazardous waste pretreatment mixing equipment and a treatment method thereof. Background technique [0002] Hazardous solid waste, referred to as hazardous waste, refers to the waste that is included in the national hazardous waste list or identified according to the national hazardous waste identification standards and identification methods, because it will cause serious impact on the environment and even the human body. It must be handled safely and properly, and in order to ensure the efficient treatment of hazardous solid waste, before its normal reaction treatment and disposal, the hazardous solid waste is generally pre-mixed to add a uniform catalyst to the hazardous solid waste etc. to ensure efficient processing and disposal. [0003] However, most of the hazardous solid waste premixing devices in the prior art have poor premixing performance. When the premixin...

[0003] However, most of the hazardous solid waste premixing devices in the prior art have poor premixing performance. When the premixing is used, the hazardous solid waste enters the mixing device through the feeding port of the mixing device for mixing. Regarding the feeding method, The existing conceivable and common ones are generally divided into fixed type and directional mobile type. The fixed type means that the position of the feed outlet is fixed, and the material is simply sent into the mixing device for mixing. The accumulation position of the material after entering is relatively fixed. In the process of continuous stirring and mixing, the materials are stirred and diffused to the surroundings. The mixing efficiency is low, and the mixing is not uniform enough in a relatively fixed period of time. In order to mix uniformly, it is necessary to prolong the mixing time, which makes the premixing time longer. As a result, the premixing efficiency is low, and the directional mobile feeding method can avoid the problem that the material accumulates in a fixed position and affects the premixing efficiency to a certain extent by moving the feeding method, but this method will make the continuous feeding In the process of feeding, within a moving feeding cycle of the moving feeding port, the stirring and mixing time of the materials at each position in the moving feeding direction is different, and within a relatively fixed period of time, the mixing time of the last entering material is the shortest. As a result, the degree of mixing of materials at each position cannot be guaranteed, which affects the uniformity of premixing. Similarly, in order to ensure the uniformity of premixing, the premixing time must be extended to ensure sufficient mixing of materials at each position. Naturally, premixing efficiency cannot be avoided. Low problem, for this reason, we propose hazardous waste pretreatment mixing equipment and its treatment method
