Problems solved by technology

There are deficiencies in today's kiln ball forming technology, which requires high moisture content of ceramsite materials. Drying first will result in high energy consumption, high drying costs, high product costs, many supporting facilities, large land occupation, and large investment, especially for moisture content. Extremely high solid waste and sludge disposal is very limited
Moreover, the ball shape of ceramsite is large, and the specification of ceramsite is single, so the application in all walks of life is very limited.

Abstract

The invention discloses a treatment apparatus and process for in-kiln balling and firing ceramsite from industrial waste residue and sludge. The treatment apparatus is characterized by comprising a bidirectional axial stirrer, a double-shaft kneader, a combustion device, a ceramsite rotary kiln and a mobile feeding screw conveyor for conveying materials to the ceramsite rotary kiln, wherein an in-kiln balling device is arranged in the ceramsite rotary kiln. According to the invention, the structure is simple, the treatment capacity of the ceramsite kiln apparatus on agglomerate, high-moisture, high-viscosity and pasty industrial solid waste and sludge is greatly improved, and the waste treatment cost is low, thereby achieving favorable popularization values.

Description

technical field [0001] The invention relates to the technical field of industrial solid waste and sludge disposal of sewage treatment plants, in particular to an environmental protection equipment and process for final disposal of industrial solid waste and excess sludge of sewage treatment plants. Background technique [0002] Ceramsite is widely used in various industries due to its characteristics of reasonable particle size distribution, small bulk density, low thermal conductivity, low water absorption, high refractoriness, good thermal insulation effect, and acid corrosion resistance. [0003] From the perspective of the construction industry only, ceramsite is an economical and practical new wall material that has developed rapidly after hollow bricks and aerated concrete blocks in recent years, and is greatly favored by the construction industry. The frame building of high-rise buildings needs ceramsite as filling material, which can reduce the weight of the building...
