Gasification device for sludge treatment

Abstract

The invention discloses a gasification device for sludge treatment. The gasification device comprises a combustion chamber, an ignition device, a fan, an air pipe assembly and a residue discharging device, wherein the air pipe assembly comprises a first air pipe and a plurality of second air pipes, the ignition device is arranged at the bottom end of the combustion chamber, and an air inlet end ofthe first air pipe is communicated with an air outlet of the fan; an air outlet end of the first air pipe is communicated with the bottom end of the combustion chamber; the plurality of second air pipes are uniformly distributed around the center axis of the combustion chamber at intervals; air outlet ends of the plurality of air outlet pipes are communicated with the bottom end of the combustionchamber, and air inlet ends of the plurality of the second air pipes are communicated with the air outlet of the fan; the air outlet end of the first air pipe is communicated with middles of the airoutlet ends of the plurality of second air pipes; the residue discharging device is communicated with the bottom end of the combustion chamber; a gas outlet is arranged at the top end of the combustion chamber. The gasification device for sludge treatment can distribute air uniformly, thus, the gasification temperature in the combustion chamber can be as high as 800 DEG C or above, and harmless decomposition of sludge is realized finally.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a gasification device for sludge treatment. Background technique [0002] At present, the special gasification device for sludge is mainly used to treat sludge and gasify the biomass with high calorific value, but the existing sludge treatment gasification device mainly has the following technical problems: due to uneven air distribution, resulting in The combustion temperature does not meet the requirements of complete gasification, and the low gasification temperature only gasifies the essence of the biomass, and the fixed carbon in it is not gasified; and the heavy metals after gasification cannot be solidified in the glass state, which cannot be realized. Fully vaporized. In addition, the gasification speed is slow and the gasification amount is small. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the purpose of the pr...
