Description

Technical Field

[0001] The invention belongs to the technical field of solid waste mixing and relates to a coupled co-firing solid waste mixing device for a coal power plant. Background Art

[0002] As a key equipment for treating solid waste and realizing efficient resource utilization in the modern coal-fired power industry, the design optimization and function improvement of the coal-fired power plant coupling solid waste mixing device are of great significance to promoting the sustainable development of the energy industry. This type of device can effectively reduce the accumulation of solid waste by mixing solid waste such as slag, fly ash, municipal waste incineration ash, etc. with coal in proportion, and can also improve the combustion efficiency of coal to a certain extent, reduce pollutant emissions, and achieve a dual improvement in environmental protection and economic benefits.

[0003] However, the coupled co-combustion solid waste mixing device for coal-fired power plants faces a series of challenges in practical application, especially in terms of cleaning, maintenance and stability of the device: Cleaning and maintenance challenges: During the cleaning process of traditional mixing devices, it is usually necessary to manually open the top cover and use brushes, shovels and other tools to clean the interior. This cleaning method is not only inefficient, but also difficult to completely remove the fine waste particles attached to the inner wall. These residues not only affect the uniformity of the next mixing, but may also become a potential source of pollution, affecting combustion efficiency and environmental quality. In addition, manual cleaning also has safety hazards, especially when handling solid waste containing toxic and harmful components, which poses a threat to the health of operators.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0024] As the problem raised in the background technology, when cleaning the coupled co-combustion solid waste mixing device used in traditional coal-fired power plants, it is usually necessary to open the top cover, and the staff can use cleaning tools to clean the inside. However, when cleaning the inner wall, some smaller waste will adhere to the inner wall, so it is not clean enough during cleaning; when most coal-fired power plants use coupled co-combustion solid waste mixing devices, the device body is often supported on the ground by the bottom support structure. When more solid waste is stirred inside the device body, the weight of the device body will increase, resulting in weaker stability when placed.

[0025] like Figure 1-6 As shown, in order to solve the above problems, the first aspect of the present invention discloses a coupling and co-combustion solid waste mixing device for coal power plants, comprising a device body 1 and a top cover 2.
