Problems solved by technology

[0006] The purpose of the present invention is to overcome the problem that the current sludge incineration directly enters the incinerator and the bulk sludge deposits on the hood, which causes serious damage to the hood due to rapid cooling and quenching. Knife slice sludge diversion device, which makes the sludge divert efficiently before entering the incinerator

Embodiment

[0019] The device of the present invention is applied in a biochemical sludge fluidized bed incineration project of a certain pharmaceutical factory. In this project, the water content of the sludge is 70% to 80%, and the incineration capacity is 100 tons / day. Before the device of the present invention is installed, the wet sludge is directly transported to the fluidized bed through the sludge pump in the sludge bin. The boiler is incinerated, and the diameter of the sludge conveying pipe is Φ219×7. Because the large sludge directly enters the fluidized bed, and cannot be diffused out in time, the low-temperature sludge may directly contact the high-temperature air cap, resulting in frequent quenching and quenching damage to the air cap. Within half a year, multiple hoods were damaged, which resulted in 2 shutdowns for maintenance. The device is welded on the lower part of the original sludge pipeline. Before the sludge enters the boiler, the sludge is quickly divided into 4 p...

Abstract

The invention discloses a sludge dividing device with cutting blades. The sludge dividing device with the cutting blades comprises a pipeline body and the two cutting blades. The two cutting blades are perpendicularly arranged in an intersecting mode and welded to the inner portion of the pipeline body. The pipeline body is welded to the lower portion of a sludge inlet incinerator pipeline. According to the sludge dividing device with the cutting blades, the structure is simple, the manufacturing cost is low, the possibility that sludge sinks to the bottom is reduced due to the design of the cutting blades, damage caused by a funnel cap is remarkably reduced, and the operation stability of a fluidized bed boiler is improved.

Description

Technical field [0001] The present invention is a technical field of sludge clean incineration, especially involving a feed device with a knife -slicing sludge diversion. Background technique [0002] The processing of sludge is an industrialized operation of economic benefits as the main driving force, and comprehensively comprehensively more sludge treatment methods and their characteristics.The advantage of the sludge incineration is that it can achieve reduction quickly and maximum. It not only solves the sludge road, and make full use of the energy in the sludge, and there is no need to consider the active treatment of the pathogenic bacteria.The thermal energy of sludge incineration can be recycled, the toxic pollutants are oxidized, and the heavy metal activity in the ashes is greatly reduced. [0003] Because the moisture content of dehydrated sludge is generally around 80%. In actual engineering, in general, the actual situation of the sludge treatment is more. If the i...
