Description

Solid waste treatment device

Technical Field

The invention relates to the technical field of solid waste treatment, in particular to a solid waste treatment device.

Background

The solid waste generally refers to solid and semi-solid waste which is generated in daily life, production and construction and other activities of human beings and cannot be utilized for a certain time and place, and is discarded to pollute the environment, wherein the solid waste comprises solid particles separated from waste gas, garbage, slag, damaged vessels, sludge and the like.

Along with the improvement of the living standard of urban residents, the yield of urban solid waste is increased greatly, the contradiction of the occupation of the urban waste is increasingly prominent, more and more urban waste, mining waste, industrial waste and the like occupy more and more land, the urban environmental sanitation is hindered, the environmental pollution is caused, large quantities of green plants are buried, and the ecological balance of the natural environment is destroyed.

Compaction is one of the common pretreatment modes of municipal solid waste, and loose solid waste is extruded by adopting compaction equipment, so that the liquid content in the solid waste can be reduced, and more importantly, the occupied area of the solid waste can be greatly reduced.

The incineration treatment technology is a technology for fully oxidizing and decomposing combustible components in the solid waste in an incinerator to form inorganic residues, the process not only realizes the reduction and the harmlessness of the solid waste, but also generates heat for power generation and heating, and the recycling of the solid waste is primarily realized.

Because the treatment capacity of the incinerator for urban incineration is limited, and the waste gas generated after incineration needs to be treated before being discharged, the total incineration capacity of the solid waste is restricted. However, the total amount of solid waste generated on a single day throughout a city is often much greater than the total amount of solid waste burned on a single day, thus resulting in the accumulation of solid waste that has not been readily disposed of by incineration. The combustible solid waste after pre-screening is subjected to compaction pretreatment, so that the occupied area of the solid waste can be obviously reduced, the water content in the solid waste can be reduced to the maximum extent, and the incineration efficiency can be greatly improved after the combustible solid waste enters the incinerator and is further air-dried. However, when the compacted massive combustible solid waste is incinerated, the compacted massive combustible solid waste is not easily burnt rapidly and only gradually burns from outside to inside due to the compaction of the solid waste, so that the incineration efficiency is greatly reduced, and the problem of incomplete incineration easily exists.
