Abstract
An anti-corrosion zirconia corundum red brick for an acid gas incinerator and a preparation process of the anti-corrosion zirconia corundum red brick belong to the field of refractory materials. The anti-corrosion zirconia corundum red brick is formed by mixing zirconia, tabular corundum, fused corundum, andalusite fine powder, a-alumina, binding clay and the like, then pressing to be formed and finally firing at high temperature. The red brick has the following advantages: firstly, acid gas corrosion is resisted, and the service cycle is prolonged; secondly, a heat-insulating layer refractory material can be protected or replaced; (3) a housing is protected. The anti-corrosion zirconia corundum red brick for the anti-corrosion zirconia corundum red brick is simple in process and high in cost performance.
Description
Technical field
The invention belongs to refractories industry, especially the corrosion-resistant zircon corundum common brick of a kind of sour gas incinerator, refer to the preparation technology that this corrosion-resistant zircon corundum common brick is provided simultaneously.
Background technology
Along with the raising of industrialization development and environmental protection standard, the sour gas incinerator developing direction becoming garbage harmless, garbage as resource.In sulphur recovery, the long-time running under 1430 DEG C of high temperature of carbon monoxide incinerator; it within 4 to 5 years, is a turnaround; in common refractory brick cannot meet its anti-erosion, resistant to elevated temperatures requirement, cannot the acid attack that is subject to of available protecting insulated lining and metal cylinder, the life-span shortens greatly.
Summary of the invention
The invention provides a kind of corrosion-resistant zircon corundum common brick of sour gas incinerator of high performance-price ratio; by the mixing such as zirconium white, plate diamond spar, andaluzite, A aluminum oxide, bonding clay repressed shaping after become refractory brick through high-temperature firing; while meeting durable energy saving; obvious opposing is by disposing acid attack; protection metal shell and insulated lining, cost performance is high.
Technical scheme of the present invention is:
The corrosion-resistant zircon corundum common brick of a kind of sour gas incinerator, the weight proportion of each component is:
Additional:
Yellow starch gum 0.3% ~ 0.6%
Methylcellulose gum 0.3% ~ 0.6%
Water 3% ~ 5%
Above-mentioned component is mixed, in mixing roll, makes pug, after being pressed into adobe, sinter goods into.
The weight proportion of each component of the present invention is:
Additional:
Yellow starch gum 0.3% ~ 0.6%
Methylcellulose gum 0.3% ~ 0.6%
Water 3% ~ 5%
A sour gas incinerator preparation technology for corrosion-resistant zircon corundum common brick, mixes raw material by ratio requirement, in mixing roll, makes pug, after being pressed into adobe, sinter goods into.
In the present invention, under 1500 tons of pressure, pug is pressed into adobe.
In the present invention, adobe sinters in hyperthermia tunnel Kiln, and sintering temperature is 1760 DEG C-1780 DEG C.
Beneficial effect of the present invention:
Product of the present invention uses through the sulphur recovery such as Nanjing petrochemical industry, Yanshan Petrochemical, Luoyang Petrochemical, Jinzhou Petrochemical Company, Tahe petrochemical industry and magnificent bright and beautiful chemical industry, carbon monoxide incinerator, efficiently solve common refractory brick, insulated lining are subject to a corrosion corrosion difficult problem by corrosion expansion disintegration and metal shell, there is the resistant to elevated temperatures advantage of resistant to corrosion, very positive effect is played to operation factor, the life cycle improving equipment.
The corrosion-resistant zircon corundum common brick of the sour gas incinerator that the present invention is fired into has the following advantages: 1) resist sour gas and corrode, extend life cycle.; 2) protection or alternative thermofin refractory materials; 3) protective housing.This sour gas incinerator is simple by corrosion-resistant zircon corundum common brick technique, and cost performance is high.
