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 combined smoke pyrolysis kiln and furnace sludge incineration device disclosed by the present invention includes a rotary pyrolysis device, an incinerator, a waste heat boiler, an air preheater and a flue gas selection device. The invention integrates the advantages of rotary kiln, pyrolysis gasifier and reciprocating grate furnace. Among them, the rotary pyrolysis gasifier is equipped with a flue gas selection device, and the flow rate, temperature and oxygen content are controllable. Mixing flue gas, stable pyrolysis gasification and anoxic combustion are carried out on the sludge entering the furnace, and the combustible gas generated during the pyrolysis process enters the second combustion chamber of the incinerator for high-temperature incineration under the action of the negative pressure of the system , the solid sludge that has not been burned during the anoxic combustion process directly falls into the reciprocating grate of the incinerator to continue incineration. The invention utilizes the residual heat in the flue gas of the system to pyrolyze the sludge, reduces energy consumption, and at the same time strictly controls the oxygen content entering the rotary kiln body, effectively avoiding the occurrence of deflagration. The invention is also equipped with a waste heat boiler, and the steam generated by the waste heat boiler is used 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...
