Hearth refractory layer and manufacturing method thereof

Abstract

The invention discloses a hearth refractory layer and a manufacturing method thereof, and relates to the technical field of hearth refractory layers of incinerators. The hearth refractory layer comprises a high-temperature-resistant brick wall layer, a first fused alumina zirconia brick wall layer, a gravel slurry layer, a second fused alumina zirconia brick wall layer, a third fused alumina zirconia brick wall layer, a first concrete layer, a second concrete layer, a third concrete layer and a fourth concrete layer. With adoption of the technical scheme, the hearth refractory layer and the manufacturing method thereof have the beneficial effects that the hearth refractory layer comprises a multi-layer refractory and high-temperature-resistant brick wall structure, the refractory and high-temperature-resistant effects are good, the structure is firm, bricks on the inner wall of a furnace body cannot fall off after long-time incineration working, and the service life is long; the masonry technology is short in man-hour, the steps are relatively simple, the labor cost is low, and the normal progress of the whole process of the hazardous waste treatment technology can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of the furnace refractory layer of an incinerator, in particular to a furnace refractory layer and a manufacturing method thereof. Background technique [0002] The incinerator is a kind of high-temperature incineration of exhaust gas, waste liquid, solid waste: for example, toxic gas (paint exhaust), toxic rocket liquid fuel, medical waste, domestic waste, animal carcasses, etc., to reduce or reduce the number of quantitative It is a kind of environmental protection equipment, and at the same time achieves a product that utilizes part of the heat energy of the incineration medium. Divided into fixed incinerators and mobile incinerators. Incineration treatment of hazardous waste has become one of the main methods for treating hazardous waste at home and abroad because of its significant volume reduction and heat recovery. However, the residue and fly ash generated during hazardous waste incineration (gener...

AI Technical Summary

Problems solved by technology

However, the residue and fly ash generated during hazardous waste incineration (generally referred to as ash residue and fly ash, accounting for about 25-35% of the total volume before treatment) contain high concentrations of heavy metals and dioxins and other harmful substances. Failure to carry out harmless treatment again will cause serious environmental pollution

[0003] Most of the incinerators currently used for hazardous waste treatment are built with brick walls, and in order to improve the fire resistance of the furnace body, the bricks used for the masonry are selected when the existing incinerators are built. A layer of ordinary brick wall and a layer of refractory brick wall constitute the incinerator body. Its fire resistance and high temperature resistance are average, and it is not strong enough. Internal damage will affect the incineration work of the entire furnace body, and even lead to the abandonment of the entire incinerator, increasing the work cost of hazardous waste treatment; and the masonry process takes a long time, the steps are more troublesome, and the labor cost is high, which affects the overall flow of the hazardous waste treatment process bigger
