A kind of hot air blowing bulk material device and using method thereof

Abstract

The invention relates to a hot wind blowing material dispersing device and a using method thereof. The hot wind blowing material dispersing device comprises a hot wind blowing pipe and a movable trolley; the hot wind blowing pipe is composed of a blowing main pipe and blowing branch pipes, and the multiple blowing branch pipes are arranged in the axial direction and the circumferential direction of the blowing main pipe; universal nozzles or blowing branch pipe plugs are selectively arranged on the blowing branch pipes; the blowing main pipe is fixed to the movable trolley, and the blowing main pipe is connected with a kiln head end plate of a rotary kiln in a sealed manner after being moved; and the end, provided with the blowing branch pipes, of the blowing main pipe stretches into the rotary kiln, and the other end of the blowing main pipe is connected with a telescopic hot wind pipeline. According to the hot wind blowing material dispersing device, by arranging a hot wind blowing device at the feeding end of the rotary kiln for incinerating solid waste, powder materials at the position of a pipe opening of a feeding pipe and on the barrel wall of a kiln barrel are blown, the materials are blown away and raised, the contact area between the materials and gas is increased, and therefore the heat transfer, drying and combusting effects are strengthened.

Description

technical field [0001] The invention relates to the technical field of solid waste incineration treatment, in particular to a hot air blowing system for blowing powder on the feed pipe nozzle of a solid waste incineration rotary kiln (rotary kiln for short) and on the wall of the kiln cylinder. Bulk material device and method of use thereof. Background technique [0002] With the rapid development of the national economy, the amount of solid waste generated has gradually increased in recent years, and solid waste treatment has become a problem that needs to be solved urgently in China. [0003] Solid waste can be divided into two categories according to different sources: domestic solid waste and industrial solid waste, which mainly include municipal solid waste, sewage treatment plant sludge, waste residue in industrial production process and sludge generated in raw material mining process Wait. At present, the relatively mature and effective solid waste treatment method ...

AI Technical Summary

Problems solved by technology

[0004] Due to the variety of solid wastes and their complex physical properties, when using a rotary kiln to incinerate powdery materials (such as sludge, oil residue, etc.), due to the small porosity of the powder after accumulation, it is difficult to combine with hot flue gas and air. The contact area is small, and its convective heat transfer and combustion will be weakened, resulting in a decrease in the burnout rate
