Abstract
The invention relates to the field of coal gas producers, in particular to a clay-based refractory brick for a coal gas producer. A formula of the clay-based refractory brick comprises the following ingredients: 45-65% of clay, 15-25% of bauxite, 10-20% of wood dust, 5-10% of tabular corundum, 1-6% of silica micropowder, 1-6% of aluminum oxide micropowder, 1-5% of kyanite, 1-4% of andalusite, 0.5-2% of calcium aluminate, 1-5% of an additive and 0.5-2% of a coagulant. The preparation process comprises the following steps of: (1) porphyrizing; (2) mixing raw materials; (3) ageing the mixture; (4) sintering; (5) performing heat preservation; (6) molding; and (7) curing. The refractory brick is simple to manufacture, controllable in cost and excellent in high temperature resistance. Furthermore, by virtue of a large amount of adopted clay and the inherent characteristics of the clay, the refractory brick has better fire performance than those of traditional refractory bricks.
Description
Technical field
The present invention relates to gas generator field, a kind of gas generator refractory brick based on clay.
Background technology
Gas generator is the production that coal is converted into imflammable gas coal gas (being mainly composed of CO, H2, CH4 etc.)
Equipment, part gas generator uses refractory brick to pile up and forms.Its operation principle is: sieved by the coal meeting gasifying process index
After choosing, firing machine join in gas stove, blast self-produced steam with air gas mixture as gasifying agent from furnace bottom.Coal exists
Through physics, chemical reaction in stove, generating imflammable gas, gas in upper segment is through cyclone oil remover, electric trapper filtered tar. hypomere
Coal gas, through cyclone dust extractor dust out, is transported to user after mixing and uses.
Refractory brick is called for short firebrick.The refractory material being fired into refractory clay or other refractory raw materials.Faint yellow or band brown.Energy
The high temperature of resistance to 1580 DEG C 1770 DEG C.Also firebrick it is.There is the refractory material of definite shape and size.By process of preparing
Division can be divided into burnt brick, unburned brick, fused cast refractories (molten-cast brick), refratory insulating brick；Standard type can be divided into by shape and size
Brick, common brick, special shaped brick etc..Can be used as building kiln and the high temperature construction material of various Thermal Equipment and structural material, and
At high temperature it is amenable to various physicochemical change and mechanism.Such as chamotte brick, high-alumina brick, silica brick, magnesia brick etc..
Clay be containing the grains of sand seldom, have the soil of stickiness, moisture to be not easy to pass therethrough and just have preferable plasticity.General
Clay is all formed by after silicate mineral at the earth's surface air slaking.General in original place air slaking, it is the most original that granule forms more greatly tap
Stone, the most primary clay or a clay.Flint clay often in block or en plaque, does not typically soak scattered in water,
Refractoriness is higher, for the primary raw material of refractory product.
