Example Embodiment

[0022] The technical solutions of the present invention are further described in detail below through the examples.

[0023] Example. See Figure 1. The sludge drying and incineration integrated device in this example has a daily sludge processing capacity of 50 tons. It consists of four functional parts connected.

[0024] I-Sludge pretreatment part: beater 2, screening machine 3, conveying pump 4, mud storage tank 6 (capacity 5m 3 ) are connected in turn, and are connected with the air flow nozzle of the spray drying tower 8 through the high pressure pump 7 (pressure is 1.5Mpa~2.4MPa).

[0025] II-Drying and incineration part: It is a spray drying tower 8 with a height of 40m and a diameter of 3.5m. The top part of the tower has an airflow nozzle / air compressor 5, a high temperature gas inlet, a tail gas outlet at the bottom of the tower, and a discharge outlet at the bottom of the tower. The nozzle of the drying tower is connected with the high pressure pump 7 and the air ...

Abstract

The invention relates to a disposal method and integrated gear of anhydration and incineration of sewage sludge. The technical problems that the invention has solved are that the anhydration of incineration of sewage sludge are integrated, the heat utilization of incineration and the comprehensive processing effect are good. The methods of the invention are that: 1) pretreatment of wet sewage sludge; 2) access to a spray head on the top of a spray drying tower (8) of the sewage sludge for spray drying after which drying particles are obtained; exhaustion of offgases from an offgas outlet at the bottom of a tower drier (8); 3) access of the drying particles to a rotary burning kiln (10) for incineration, with the high temperature gases needed by the startup and operation of the rotary burning kiln (10) supplied by a hot-blast stove; exhaustion of the slag particles from a slag outlet; 4) access of the high temperature gases from the rotary burning kiln (10) to a second combustion chamber (9) for sufficient combustion; delivery of the high temperature gases after combustion to the spray drying tower (8).

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a sludge drying and incineration treatment method and an integrated device. Can also be applied to silt. Background technique [0002] Sludge treatment technology is a major issue in the field of environmental protection, and the technical solutions have their own advantages and disadvantages. Chinese patent document CN1931752A discloses "a wet sludge incineration treatment device with a particle dryer". In addition to the circulating fluidized bed incinerator, the device also has a sludge breaking device and a particle dryer. It concentrates the drying and incineration of wet sludge in one device. A large amount of moisture contained in the wet sludge is drawn out with the fluidized gas of the particle dryer, or recycled as the fluidized gas of the particle dryer or sent to the furnace for incineration, so as to reduce the heat loss of the system and not emit odorous ...
