AI Technical Summary

Technical Problem

In existing waste incineration power generation flue gas treatment systems, pipe-through injection has low mixing efficiency, central shock cone injection has high operating resistance and large space requirements, and multi-point high-dispersion injection is prone to caking and difficult to clean.

Method used

A new type of high-dispersion material spraying device is adopted, including a main spraying ring pipe, four spraying pipes and a compressed air main pipe. The spraying pipes are arranged counterclockwise along the circumference. The diameter and angle of the spraying pipes are reasonably designed. Combined with the regulating valve to control the compressed air flow, the material is uniformly dispersed.

Benefits of technology

It improves the uniformity and dispersion of materials in the flue, reduces operating resistance, lowers the risk of end-point blockage, and enhances mixing efficiency and equipment lifespan.

Abstract

The application discloses a novel material high-dispersion spraying device, which comprises a main spraying ring pipe, a first spraying pipe, a second spraying pipe, a third spraying pipe, a fourth spraying pipe and a compressed air main pipe. The open end of the first spraying pipe, the open end of the second spraying pipe, the open end of the third spraying pipe and the open end of the fourth spraying pipe are arranged on the circumference of the inlet flue of a bag-type dust collector; the other end of the first spraying pipe, the other end of the second spraying pipe, the other end of the third spraying pipe and the other end of the fourth spraying pipe penetrate the main spraying ring pipe and flow into the compressed air main pipe, and the compressed air main pipe is arranged vertically. The material enters the first spraying pipe, the second spraying pipe, the third spraying pipe and the fourth spraying pipe from the main spraying ring pipe and enters the flue under the action of the compressed air main pipe. Since four spraying pipes are arranged on the main spraying ring pipe, the uniformity and dispersity of the material entering the flue can be improved.
