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 )

Embodiment Construction

[0013] The technical characteristics of the present invention will be further described below in conjunction with the accompanying drawings through the preferred embodiments.

[0014] See attached drawings 1-3 for details, a cavity glazed acid-resistant brick, including a brick body 1 with a glazed surface 5, and more than one cavity 3 is arranged inside the brick body, and the number of cavities can be set according to different specifications Multiple cavities3. The shape of the horizontal cross-section of the cavity of the brick body is various shapes such as quadrangle, circle or ellipse, and can be applied to brick bodies of various shapes and specifications used in various chimneys or flue linings. The cavity is provided with an air vent 4, which can prevent the cavity from bursting during the firing process of the adobe. The cavity is the hollow inside the brick body and the cover 2 is added or the cover is respectively arranged in the hollow opening of the brick body ...

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...
