The invention relates to the field of environmental protection, in particular to the field of household garbage treatment, and specifically relates to a combustion and purification integrated furnace and application thereof. More specifically, the application provides a burning purifies integrative stove for organic matter is handled and uses thereof, and it is at the in-process of burning domestic waste, can realize the purification treatment to the flue gas, and then realizes the treatment effect of no flue gas.

Background

In daily life, a large amount of household garbage is always generated. With the development of economy and the improvement of the living standard of people, the production amount of domestic garbage is increasing day by day. The recyclable articles in the household garbage, such as glass, metal and the like, are generally recycled due to certain economic value. The plastic bags, leaves, kitchen waste and the like in the household garbage are generally treated by two modes of garbage landfill and garbage incineration power generation due to the defects of high recovery difficulty, low recovery value and the like.

Wherein, the garbage landfill is to extrude the garbage into blocks and then transfer the blocks to a garbage landfill site for landfill treatment. The landfill treatment has low requirement on equipment and low cost, and is more common in early years. However, under the influence of rain water and the like, the penetrating fluid in the landfill site flows out along with the water flow, and pollutes the surrounding soil and underground water. Meanwhile, the landfill occupies a large amount of land; along with the development of society, the production amount of garbage is increasing day by day, and the demand of garbage landfill sites for land is increasing day by day.

The waste incineration is to treat the waste in an incineration mode. Compared with a garbage landfill treatment mode, the garbage incineration has great advantages in the aspects of reduction, harmlessness, resource utilization and the like, and the garbage incineration treatment method is widely applied to large and medium-sized cities with dense population, short land resources and high garbage heat value and coastal economically developed areas.

In the household garbage, plastic products represented by plastic bags, kitchen waste, dry branches and fallen leaves and the like are included, so that the household garbage has the characteristics of large volume and large quantity, and a large amount of land can be occupied by adopting a landfill mode. In view of the above problems, incineration of household garbage tends to be a trend. At present, a waste incineration power plant is generally established in the center of a city or a district, and household waste is treated by the waste incineration power plant, wherein the waste treatment capacity is more than 300 tons/day. However, the investment of a single waste incineration power plant is generally in billions of units, which is costly. On the other hand, small-sized waste incineration equipment is usually relatively low in price, but a large amount of smoke is generated in the incineration process, and certain influence is caused on the environment. Meanwhile, the transportation of the domestic garbage is a huge problem due to the large amount of the domestic garbage.

Therefore, the application provides a smokeless waste treatment device and application thereof to solve the problems.
