Description

Technical Field

[0001] The invention relates to the technical field of turbine casings, and in particular to a turbine casing capable of reducing noise and dust. Background Art

[0002] The turbine fan rotates the impeller at high speed. The blades in the impeller force the gas to rotate, doing work on the gas and increasing its momentum. Under the action of centrifugal force, the gas is thrown around the impeller and converts kinetic energy into pressure energy through the turbine casing to supply air to the equipment.

[0003] During the operation of the turbine fan, particulate impurities may be sucked into the air inlet of the turbine fan. The high-speed rotating impeller may collide with the particles and cause damage. The discharged particle dust may also affect the equipment that requires air supply, and the dust accumulated on the impeller may also make the impeller produce louder noise, affecting the working environment. Summary of the invention

[0004] The technical problem solved by the present invention is to provide a turbine casing with noise and dust reduction to solve the problems raised in the above-mentioned background technology.
