Embodiment

[0290] Embodiment: An operation method of an integrated device for synergistic treatment of industrial solid waste and sludge rotary kiln is carried out according to the following steps:

[0291] (1) Structural composition:

[0292] Including sludge receiving system, sludge spray drying or disc drying system, sludge incineration system, flue gas treatment system, wind slag suction system and incineration slag collection system;

[0293] The sludge receiving system, sludge spray drying or disk drying system, sludge incineration system, flue gas treatment system, wind slag suction system and incineration slag collection system are connected in sequence;

[0294] (2) Sludge feeding system:

[0295] Sludge is received in two ways:

[0296] The first way: the sludge with a moisture content of 70%-80% is poured into the underground receiving system, then lifted by the shaftless auger, the screw pump is sent to the large sludge storage tank through the filter, and then the sludge i...

Abstract

The invention relates to a co-processing integrated device, in particular to an operation method of an industrial solid waste and sludge rotary kiln co-processing integrated device. The sludge spray drying (direct drying) + disc drying (indirect drying), rotary kiln and industrial leftover material (solid waste) collaborative incineration and flue gas purification system integrated device integrates sludge drying, sludge drying and industrial leftover material (solid waste) collaborative incineration and flue gas purification, achieves waste reutilization and reduces environmental pollution.

Description

technical field [0001] The invention relates to a cooperative processing integrated device, in particular to an operation method of an industrial solid waste and sludge rotary kiln cooperative processing integrated device. Background technique [0002] With the construction and operation of a large number of sewage treatment plants across my country, the sewage treatment rate has increased significantly, and the sludge output has also increased simultaneously. Based on a moisture content of 80%, by the end of 2012, the total annual sludge output in China had exceeded 30 million tons. According to forecasts, by 2020, the amount of sludge will exceed 60 million tons per year. Sewage plant sludge contains organic matter, heavy metals, pathogenic microorganisms and other toxic and harmful substances contained in sewage, which has greater biological toxicity. On the other hand, the "Water Ten Measures" issued in April 2015 further stipulates the promotion of sludge treatment an...
