Abstract

Abstract

To improve the problem of poor pulse cleaning of the filter element, this paper took the special-shaped filter element as the research object, and the pulse injection performance under the combination of filter element shape, nozzle angle, and injection pressure difference was investigated, also the numerical model of pulse injection was built. The flow field inside the filter element was simulated and analyzed by Ansys Fluent software. The results showed that the static pressure in the collision zone of the inverted trapezoid and contractile filter was larger, while that in the trapezoid and bulging filter was smaller. When the nozzle angle increased from -45° to 45°, the injection pressure and performance of the straight cylinder and shrink filter element increased first and then decreased, and the optimal nozzle angle was 30°. Increasing the injection pressure difference PR helped improve the injection performance of the filter element, and the pressure difference had a stronger effect on the injection performance of the shrink filter element than that of the straight cylinder filter element. Generally, the shrinkage structure of the dust filter element is beneficial to improve the cleaning performance of the pulse injection.
