Abstract

The invention discloses a sludge incineration utilization system, which comprises a furnace body, a screw extruder and a smoke exhaust pipe are installed on the upper part of the furnace body, a discharge pipe is installed at the extrusion port of the screw extruder, and a fixing frame is installed on the bottom of the furnace body. A fixed rod is installed in the middle part of the fixed frame, and a bearing is installed in the middle part of the fixed rod. The present invention disturbs the flame in the process of sludge combustion through a simple and effective structure and process, so that the organic matter and oxygen in the flame can be fully contacted, so that harmful substances such as benzopyrene and aromatic compounds in the sludge Complete combustion prevents harmful substances such as benzopyrene and aromatic compounds from being discharged into the atmosphere, and the removal rate of harmful substances such as benzopyrene and aromatic compounds increases from less than 50% to more than 89.3%.

Description

technical field [0001] The invention relates to an incineration utilization system, more precisely a sludge incineration utilization system. Background technique [0002] Sludge incineration is a process of sludge treatment. It uses an incinerator to heat and dry the dewatered sludge, and then uses high temperature to oxidize the organic matter in the sludge to make the sludge a small amount of ash. In the process of sludge incineration in the existing sludge incinerator, on the one hand, the ignition point of the sludge is unstable, and the sludge layer accumulated together during combustion is likely to cause oxygen deficiency and extinguish, and the use and maintenance are complicated; on the other hand, Harmful substances such as benzopyrene and aromatic compounds in the sludge cannot be completely burned, and will be discharged into the atmosphere along with the flue gas, causing environmental pollution. Contents of the invention [0003] The object of the present i...
