AI Technical Summary

Technical Problem

In existing deep dry desulfurization and denitrification methods for biomass boilers, the lag in waste heat recovery leads to serious energy waste, high system energy consumption, low equipment integration, and the inability to carry out purification and waste heat recovery simultaneously.

Method used

A composite waste heat recovery mechanism for biomass power generation boilers based on phase change equilibrium is adopted. Through the coordinated design of cyclone dust collector, purification components, scraping components and heat exchange components, the mixture of high-temperature flue gas and powder is slowly transported under the guidance of spiral blades, so as to carry out purification and waste heat recovery in a coordinated manner.

Benefits of technology

It achieves efficient purification and waste heat recovery in synergy, improves the waste heat recovery utilization rate, reduces system energy consumption, enhances equipment integration, and reduces floor space and operating costs.

Abstract

This invention relates to the field of boiler waste heat recovery technology, and more particularly to a composite waste heat recovery mechanism for biomass power generation boilers based on phase change equilibrium. This invention provides a composite waste heat recovery mechanism for biomass power generation boilers based on phase change equilibrium that enables synergistic purification and waste heat recovery. The composite waste heat recovery mechanism for biomass power generation boilers based on phase change equilibrium includes a support frame, fixing screws, a cyclone dust collector, and purification components. The cyclone dust collector is detachably connected to the upper part of the support frame via multiple fixing screws. The cyclone dust collector is equipped with purification components for purifying high-temperature flue gas. In this invention, when the high-temperature flue gas and powder mixture are slowly conveyed downwards along the spiral blades, the heat in the high-temperature flue gas is conducted through the reaction vessel to the low-temperature medium in the heat exchange tubes, achieving waste heat recovery from the flue gas and achieving the effect of synergistic purification and waste heat recovery.
