Sludge fast heat drying treating device and sludge fast heat drying treating method

Abstract

The invention relates to a sludge fast heat drying treating device, which is composed of a controllable explosion combustor, a sludge conveying mechanism and a rear dryer. The controllable explosion combustor is composed of a combustion chamber, an igniter, an air inlet pipeline, a gas inlet pipeline, a tail pipe and a jacket, the combustion chamber is fixedly installed in the jacket, the air inlet pipeline, the gas inlet pipeline and the igniter are fixedly installed on the combustion chamber, the tail pipe is installed in the jacket fixedly, one end of the tail pipe is communicated with the combustion chamber, the other end of the tail pipe extends out of the jacket to be communicated with the rear dryer, the sludge conveying mechanism is fixedly installed above the outside of the jacket, and the tail end of the sludge conveying mechanism extends into the jacket to be communicated with the jacket. The sludge fast heat drying treating device has the advantages of being simple in structure, fast in drying, low in energy consumption of drying and even in sludge particle size and capable of leading the particles to be not apt to stick onto the wall and the like. Further, the heat drying treating method has the advantages of being simple in process, easy to achieve and good in effect. The sludge fast heat drying treating device is high in innovation.

Description

technical field [0001] The invention belongs to the field of sludge treatment and resource utilization equipment, and in particular relates to a sludge rapid thermal drying treatment device and method. Background technique [0002] Sludge is a solid waste produced by municipal sewage treatment, which contains a large amount of organic matter and pathogenic bacteria. If it is not handled properly, it will easily have adverse effects on the urban environment and residents' health. By the end of 2009, there were 3,134 urban sewage treatment plants nationwide, with a total treatment capacity of 111.6 million cubic meters per day, and 21.24 million tons of sludge with a moisture content of 80% per year. In 2015, the amount of urban sludge in my country is expected to reach 31.43 million tons per year. Therefore, it is one of the important challenges facing urban development in my country to carry out safe and standardized treatment and disposal of urban sludge and realize sludge...

Problems solved by technology

In addition, when the sludge slurry is atomized by the nozzle, the intense friction between the sludge slurry and the nozzle will cause the nozzle to wear, and the nozzle needs to be replaced frequently, resulting in shutdown and reduced production efficiency
