一种循环流化床锅炉内置翻板阀及其SCR脱硝系统
By designing a thick-walled structure with a built-in flap valve and an adjustable counterweight torque, the problems of easy deformation and poor sealing of traditional flap valves are solved. This achieves a precise balance between efficient reducing agent evaporation and gasification and airlock ash discharge, improving the operational stability and denitrification efficiency of the circulating fluidized bed boiler.

AI Technical Summary
Traditional circulating fluidized bed boiler flap valves are prone to deformation and have poor sealing performance. The counterweight torque cannot be adjusted, and the bushing is prone to ash ingress. They have limited functionality and cannot meet the needs of airlocking and ash discharge under different operating conditions. Furthermore, they cannot effectively utilize the heat of high-temperature flue gas or fly ash for the evaporation and gasification of reducing agents.
Design a built-in flap valve with an integrated thick-walled flap plate, setting up an evaporation zone and a liquid inlet zone. It uses a heat storage column to absorb the heat of high-temperature flue gas or fly ash for reducing agent evaporation. Through a combined anti-ash bushing and a counterweight component with adjustable counterweight torque, the flap plate can be flexibly rotated and the sealing performance can be improved. At the same time, it is linked with the SCR denitrification system.
It improves the sealing performance and operational stability of the flap valve, realizes the efficient evaporation and vaporization of the reducing agent, simplifies the structure of the denitrification system, reduces equipment costs and energy consumption, and improves denitrification efficiency.
