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

[0016] 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 invention belongs to the technical field of sludge cleaning and incineration disposal, and in particular relates to a feeding device with a knife for slicing and diverting sludge. Background technique [0002] Sludge treatment is an industrial operation method driven mainly by economic benefits, and a variety of sludge treatment methods and their characteristics are compared comprehensively. The advantage of sludge incineration is that it can achieve rapid and maximum reduction. It not only solves the sludge outlet but also makes full use of the energy in the sludge, and does not need to consider the inactivation of pathogenic bacteria. The heat energy of sludge incineration can be recycled, toxic pollutants are oxidized, and the activity of heavy metals in ash is greatly reduced. [0003] Since the moisture content of dewatered sludge is generally about 80%, in actual projects, generally, the actual situation is that the sludge treatment volume i...
