Description

Garbage incinerator lining structure based on scouring-resistant silicon carbide zirconium bricks

Technical Field

The utility model relates to the technical field of environmental protection chemical industry, in particular to a washing-resistant silicon carbide zirconium brick-based lining structure of a waste incinerator.

Background

The garbage incinerator is used for incinerating garbage, the garbage is burnt in the hearth to become waste gas, the waste gas enters the secondary combustion chamber, the waste gas is completely combusted under the forced combustion of the combustor, and then enters the spray type dust remover, and the waste gas is discharged into the atmosphere through a chimney after dust removal. The garbage incinerator consists of four systems, namely a garbage pretreatment system, an incineration system, a smoke biochemical dust removal system and a gas producer (auxiliary ignition incineration), and integrates automatic feeding, screening, drying, incineration, ash removal, dust removal and automatic control. The garbage incinerator is a harmless treatment device which is commonly used for harmless treatment of medical and domestic wastes and animals. The principle is that the objects to be treated are incinerated and carbonized at high temperature by utilizing the combustion of fuels such as coal, fuel oil, fuel gas and the like so as to achieve the aim of disinfection treatment.

The existing incinerator lining refractory material is easy to find serious erosion stripping in about one year, and particularly the erosion stripping is the most serious at the upper 1/4 part of the upper inclined section and the middle straight section.

Analysis can be carried out according to the current situation, when the waste liquid is normally atomized by injection, the corrosion stripping of the lining of the incinerator is mainly caused by that part of the insufficiently combusted waste liquid and the combustion products of the waste liquid are in contact with the lining of the incinerator wall to react, so that compounds which can damage the lining are generated on the surface of the incinerator lining, the lining is cracked, and the reacted chemicals are easy to strip from the surface of the lining, so that the cracked lining is separated away, the lining of the incinerator is gradually thinned, 1/4 parts on an upper inclined section and a middle straight section are mixed main reaction areas, the positions where the atomized waste liquid and the combustion products are most accumulated on the incinerator wall are the most, the contact reaction is the most serious, and the corrosion stripping is the most serious; when the waste liquid is abnormally sprayed and atomized, most of the waste liquid is directly sprayed onto the furnace lining, so that the temperature of the local lining subjected to scouring is sharply reduced, and a temperature difference is formed between the local lining and the surrounding furnace lining layer, thereby generating internal stress, when the internal stress exceeds the strength of the furnace lining, cracks are generated, and are continuously expanded and extended along with the lapse of time, so that the furnace lining is broken and thinned, and 1/4 parts on the upper inclined section and the middle straight section are the parts which are most directly contacted with scouring erosion, so that the erosion stripping is the most serious.

Therefore, an incinerator lining structure which can resist corrosion, high temperature and scouring is urgently needed.
