Heat insulating sludge drying incineration device and heat insulating sludge drying incineration method

Abstract

The invention relates to a heat insulating sludge drying incineration device and a heat insulating sludge drying incineration method. The device consists of a conveyor, a lifting machine, a sludge incinerator, an active carbon jetting system, a flying ash recirculating system, a dust remover and a chimney, wherein the lifting machine is arranged at the discharging end of the conveyor; a sludge hopper is arranged on the lifting machine; the discharging end of the lifting machine is connected with a charging port of the sludge incinerator; the active carbon jetting system is used for jetting active carbon into the sludge incinerator; one end of the dust remover is connected with the sludge incinerator through a pipeline; the other end of the dust remover is connected with the chimney through the pipeline; and the flying ash recirculating system is respectively connected with the dust remover and the sludge incinerator. The device has the advantages of energy conservation, environment friendliness, low construction cost, stability in operation, reasonability in technological design, and low investment and operation cost; and moreover, the innocent treatment is realized.

Description

technical field [0001] The invention relates to a thermal insulation sludge drying and incineration device and method, belonging to the technical field of environmental protection. Background technique [0002] Developed countries such as Europe, the United States, and Japan pay great attention to the disposal of sludge while treating sewage, and spend huge sums of money on the harmless disposal of sludge. Especially in the past ten years, with the continuous advancement of technology, countries such as Europe, the United States, and Japan have adopted a large number of new technologies to dispose of sludge from sewage treatment plants. With the vigorous development of urban sewage treatment in my country, the amount of sludge discharged from urban sewage treatment plants is increasing. However, the treatment and disposal of sludge is a weak link that plagues the healthy development of the sewage treatment industry. In recent years, the reduction, harmlessness, and resource...

Problems solved by technology

The former is mainly suitable for areas with dry climates. It is characterized by less drying equipment, energy consumption is mainly electric energy, and relatively low operating costs. However, it occupies a large area and is easily affected by the ambient temperature and humidity. The working environment is relatively poor. The latter has a wider scope of application and can be used for drying various materials without being affected by regions and climates. It has a high degree of automation, stable and reliable operation, and its energy consumption is mainly electric energy and heat energy. The operating cost is relatively high.

[0004] The dried sludge is mainly disposed of in a landfill. The landfill is generally built in a place far away from the city and the crowd. The sludge transportation distance is long, the cost is high, and the pollution of the road along the way is serious. At the same time, the landfill is built It also requires a lot of money and space; in addition, the sludge in the landfill is undergoing biological, chemical, and physical reactions all the time, producing a large amount of harmful gases and seepage fluids, which can easily pollute the atmosphere, water embankments, and soil. Therefore, landfills need Equipped with special management personnel and testing personnel for management
