Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] see figure 1 , the combined smoke pyrolysis kiln and furnace sludge incineration device shown in the figure includes a rotary pyrolysis device 100, an incinerator 200, a waste heat boiler 300, an air preheater 400 and a Taiyan wind matching device 500.

[0031] The rotary pyrolysis device 100 includes a rotary kiln body 110, a rotary kiln body support 120, and a rotary kiln body drive mechanism 130. The rotary kiln body drive mechanism 130 is installed on the rotary kiln body support 120 to support the rotary kiln body 110 and Drive the rotary kiln body 110 to rotate. The drive mechanism 130 of the rotary kiln body is driven by a frequency conversion speed control device to meet the needs of different sludge pyrolysis conditions.

[0032] The rotary kiln body 110 has two opposite ends, one of which is the feed end 111, and the other e...

Abstract

The invention discloses a smoke pyrolysis kiln-furnace-combined type sludge incinerator. The smoke pyrolysis kiln-furnace-combined type sludge incinerator comprises a rotary pyrolysis device, an incineration furnace, a waste heat boiler, an air preheater and a smoke distribution device and integrates the advantages of a rotary kiln, a pyrolysis gasifier and a reciprocating grate furnace; a rotary pyrolysis gasifier is provided with the smoke distribution device and mixes and distributes smoke in a flow temperature and oxygen content adjustable mode to achieve stable pyrolysis gasification and anoxic combustion of in-furnace sludge, combustible gas generated during the pyrolysis process can enter two combustion chambers of the incineration furnace under the action of system negative pressure for high-temperature incineration; unburnt solid sludge during the anoxic combustion can directly drop on the reciprocating grate of the incineration furnace for continuous incineration. According to the smoke pyrolysis kiln-furnace-combined type sludge incinerator, sludge is pyrolyzed through waste heat inside system smoke, so that energy consumption can be reduced; meanwhile, the content of oxygen entering the rotary kiln is strictly controlled, detonation can be effectively avoided; the waste heat boiler can generate steam for heat supply and power generation.

Description

technical field [0001] The invention relates to the technical field of sludge incineration treatment, in particular to a smoke pyrolysis kiln and furnace combined sludge incineration device. Background technique [0002] The sludge incinerator should at least complete the two basic functions of sludge incineration and providing heat source for sludge drying. In terms of incineration characteristics, sludge has the characteristics that are very different from general fuels: it has a large ash content and a large internal moisture content. Therefore, the calorific value is low; its combustible base has high volatile content and fine particles, so it is easy to burn. [0003] Among the commonly used sludge incineration treatment technologies in the domestic market, comprehensive analysis of their respective incineration treatment results shows that its fluidized bed sludge incineration treatment technology is at the leading level. The main technical features of the circulating...
