Hollow glazed-face acid-resistant brick

Abstract

The invention relates to a chimney construction antiseptic material that includes the brick containing glaze. The feature is that at least one cavity is installed in the brick, and exhaust vent is set on it. It has the advantages of high density, low water absorption, and good acid resistance. It ensures the quality of brick placing.

Description

technical field [0001] The invention belongs to anticorrosion materials for chimney construction, in particular to a hollow glazed acid-resistant brick suitable for chimney inner lining. Background technique [0002] In order to solve the deteriorating natural environmental problems, the State Environmental Protection Administration reiterated the environmental protection regulations to strictly control the emission of sulfur dioxide. At present, in order to meet the standard thermal power plants generally use wet flue gas desulfurization. The flue gas after desulfurization treatment has high moisture content, high humidity, and low temperature, which is prone to condensation in the flue gas, and the flue gas contains a large amount of strong corrosive substances such as hydrogen fluoride and chloride. Therefore, the chimney of the power plant requires good corrosion resistance and impermeability. Generally, there are two types of anti-corrosion and acid-resistant bricks f...

AI Technical Summary

Problems solved by technology

Its advantage is small bulk density, but its disadvantages are high water absorption (10-15%) and no impermeability; the other is commonly used in the chemical industry to make ceramic solid bricks with ceramic materials, which have low water absorption (≤4%), The impermeability is good, but the disadvantage is that the capacity is large (2300-2400kg / m 3 )
