Abstract

The invention belongs to the technical field of heat energy and power equipment and particularly relates to a variable flow whirlcone. The variable flow whirlcone comprises a rotatable inner hub, a fixed-type outer hub and rotatable blades, one sides of the rotatable blades are mounted on the fixed-type outer hub, and the other sides of the rotatable blades are mounted on the rotatable inner hub.The rotatable inner hub comprises an inner hub bottom plate and an inner hub outlet ring way, the fixed-type outer hub comprises an outer hub bottom plate and an outer hub outlet ring way, and the rotatable blades comprise rotatable blade bodies, first blade sliding shafts, first blade rotating shafts, second blade sliding shafts and second blade rotating shafts. According to the variable flow whirlcone, the blade mounting angle and the through flow area of the whirlcone can be changed, thus the flow of air entering the whirlcone and the swirling number can be changed, the defect that as for atraditional fixed-type whirlcone, the blade angle and the air flow cannot be adjusted is overcome, and non-detachable online adjustment of the whirlcone is achieved; and the time of shutting down forreplacing and test adjustment is saved, and the utilization rate of the variable flow whirlcone is increased.

Description

Technical field: [0001] The invention belongs to the technical field of thermal energy and power equipment, and in particular relates to a variable flow cyclone. Background technique: [0002] With the increasingly stringent environmental protection of oceans, ports and the atmosphere, countries around the world have put forward stricter and stricter limits on pollutant emissions from gas turbine combustors. In the compact space with high heat load in the combustor of ships and industrial gas turbines, in order to maintain high combustion efficiency and flame stability, and to achieve the required pollutant emission indicators, it is necessary to adopt low-emission combustion technology and control NOx at the same time and CO emissions. However, in conventional combustion chambers, the two are contradictory. How to reduce NOx emissions and ensure that CO emissions meet the standards in a wide range of working conditions is the main technical problem to be solved by the pre...
