Description

TECHNICAL FIELD

[0001] The application relates to the technical field of sludge combustion, in particular to a solid waste sludge combustion device. BACKGROUND

[0002] Solid waste sludge refers to a mixture containing solid particles and a large amount of water generated in the processes of water treatment, wastewater treatment, sewage treatment and urban sewage treatment.

[0003] The solid waste sludge combustion device decomposes and converts organic matter in the sludge through high-temperature combustion, and realizes the reduction and harmless treatment of the sludge at the same time. This device has important significance in the environmental protection field and can effectively solve the sludge treatment problem and reduce environmental pollution.

[0004] For example, the patent with the publication number CN214840832U discloses a municipal sludge incinerator. When the sludge in the furnace body is incinerated, the next group of sludge is placed on the filter screen through the feed inlet. The water in the sludge will fall onto the guide plate under the action of gravity, and then the water flow will flow out of the furnace body along the end face of the guide plate under the action of its own gravity. In addition, the heat energy generated during the incineration of the furnace body can dry the sludge on the filter screen, further removing the water in the sludge to be incinerated. This process is synchronized with the incineration process, has high efficiency, and reduces the use of external sludge water removal equipment.
