Hazardous waste pretreatment mixing equipment and its treatment method

Abstract

The invention discloses a hazardous waste pretreatment mixing device and a treatment method thereof, including a double-helix stirring device, and a uniform feeding mechanism is fixed on the top of the double-helix stirring device to ensure that all materials are synchronized and uniformly stirred to effectively control the stirring efficiency. Hazardous waste pretreatment mixing equipment and its treatment method are different from the existing technology. During the real-time pretreatment and mixing process of hazardous waste, it can ensure that the materials are continuously and stably scattered, and ensure that the hazardous waste materials are pre-mixed and stirred. It is effectively diffused, and after the material enters the mixing equipment, the mixing time of the material at each mixing position is the same to ensure the synchronous mixing of the materials at each position, so as to ensure the uniformity of the mixing of hazardous waste materials within a relatively fixed period of time. , effectively improving the efficiency of premixing treatment of hazardous waste materials.

Description

technical field [0001] The invention relates to the technical field of mixing equipment, in particular to a hazardous waste pretreatment mixing equipment and a processing method thereof. Background technique [0002] Hazardous solid waste, referred to as hazardous waste, refers to the waste that is listed in the national hazardous waste list or identified according to the national hazardous waste identification standards and identification methods. It must be disposed of 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 disposal. [0003] However, most of the pre-mixing devices for hazardous solid waste in the prior art have poor pre-mixing performance. When pre-mixing is used, the hazardous solid waste enters the mixing device through the feed port of ...

Problems solved by technology

[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
