Description

A tumbling small domestic waste incinerator and tumbling incineration method

technical field

The invention relates to the field of harmless and reduction disposal of household garbage, in particular to a small clean incinerator for household garbage.

Background technique

With the continuous increase of non-degradable components in domestic waste, centralized incineration is a better choice for the reduction, harmlessness and resourceful disposal of urban domestic waste in the future. However, for vast rural areas, it is unrealistic to use large-scale incinerators for centralized incineration because the garbage is scattered and difficult to concentrate on a large scale. In order to solve the garbage problem in rural areas, especially in remote villages, a small-scale collection is used to clean and incinerate the garbage on the spot to realize the harmless and reduced decentralized disposal of garbage. It does not require high advantages and is in line with the current level of social and economic development in the vast rural areas of our country.

A relatively common method of decentralized disposal of rural domestic waste is to use small incinerators to incinerate domestic waste, and the incinerated flue gas will be treated and discharged after reaching the standard. Compared with cities, the domestic garbage removal and transportation system in villages and towns is not perfect. It is difficult to ensure that the garbage of the day is sent to the incineration station in a timely manner, and the moisture content and decay of garbage are affected by factors such as weather and seasons. The composition and state of garbage are more complex than MSW. For small incineration plants, it is difficult to adjust the calorific value of waste, reduce moisture content, break bags, sieve, and homogenize a series of pretreatment measures like large incineration plants, and it is also difficult to adjust in real time through complex means. Incineration parameters to control the incineration process. The above situation has brought great difficulty to the design of small incinerators.

For the current traditional small incinerators, once the garbage is incinerated, the incineration status of each part of the garbage in different parts varies greatly due to factors such as density, composition, and oxygen demand. In some parts, the incineration speed is faster due to loose accumulation of garbage, better flammability, and less oxygen consumption of components, while in some parts, the incineration is faster due to denser garbage, poor flammability, and more oxygen consumption in combustion of components. The speed is slower; the parts with fast burning speed will form airflow channels as the garbage burns out, causing more and more combustion air to flow through these "short-circuit channels" with less resistance, while those parts with dense garbage have to Without sufficient oxygen, it is in a smoldering state of hypoxia. In the smoldering state of garbage, not only the harmful components such as unburned hydrocarbons will increase greatly, but also it is difficult to increase the temperature of the furnace, so that the generated harmful substances cannot be incinerated in a high temperature environment, resulting in the total amount of harmful pollutants in the flue gas discharged from the incinerator. The content is very high, which greatly increases the workload of the post-treatment system, thereby increasing equipment investment and operating costs, which is why the cost of the flue gas treatment of small incinerators is much higher than that of incineration.

If a small-scale garbage incinerator can be developed, it can overcome the unevenness of garbage incineration in the furnace, improve the relationship between garbage and air, and then reduce the total amount of harmful substances generated in the incineration process, which will help reduce the load of the flue gas treatment process , Save the investment and operating costs of the entire incineration system, which is of great significance to the disposal of rural domestic waste.
