AI Technical Summary

Technical Problem

Traditional boilers suffer from problems such as waste of resources and serious harm to human health due to the mixing and collection of pulverized coal and ash during operation, and the dust generated during cleaning.

Method used

Design a device for recovering coal ash and coal powder from a boiler. The boiler is divided into three chambers by a partition plate inside the shell. The chambers are connected by an induced draft section and a regulating section to create a negative pressure, which collects coal powder and coal ash separately. The material collection section is then used for separation and recovery.

Benefits of technology

It enables the separation and recycling of coal powder and coal ash, reduces resource waste, improves the cleaning environment, reduces the risk of dust flying, and improves cleaning efficiency and safety.

Abstract

The utility model belongs to the technical field of boiler fuel recovery, and particularly relates to a device for recovering coal ash and pulverized coal of a boiler. The partition plate is fixed in the shell and divides the interior of the shell into a first cavity, a second cavity and a third cavity; the material collecting part is arranged on the outer wall of the shell and extends towards the interior of the shell, and the extending positions are located in the first cavity and the second cavity correspondingly. The air inducing part is arranged outside the shell; the adjusting part is arranged in the third cavity of the shell, the input end of the adjusting part is connected with the air inducing part, and the output end of the adjusting part extends and communicates into the first cavity and the second cavity. On one hand, the problem of energy waste caused by the fact that pulverized coal is treated as garbage is solved, and on the other hand, the problems that human bodies are hurt and manpower and material resources are wasted due to manual cleaning are solved.
