摘要：

The effects of the nozzle size and its shape for the pulse cleaning of a ceramic filter candle were observed experimentally in the hot and cold bench units using commercial filter elements. The traces of the transient pressure, temperature, and overpressure in the filter cavity were measured to estimate the pulse cleaning effects. At the given pulse cleaning system, the pulse cleaning was optimized by the reciprocal effect of the nozzle size, which increases the primary pulse gas mass and reduces the secondary pulse mass as its size increases. The convergent nozzle showed a higher pulse effect than the straight one due to its concentrating effect, which leads to high pressure of the gas leaving the pulse nozzle.
