First, the foreword

Pulse bag type dust collector in China's development over the past more than and 20 years, due to the introduction of new technology, coupled with the efforts of colleagues and struggle, bag filter effect, has been unanimously endorsed by the majority of users.

Dedicated to the research and development of electromagnetic pulse valve, automatic control system, filter bag, bag cage bag type dust collector accessories. In order to study deeply on the system, we will study the object to expand to the entire bag type dust collector. Pulse cleaning system is the core part of pulse bag filter, through more than and 10 years of research and manufacture of bag filter, the performance of electromagnetic pulse valve and ash cleaning system has been improved. At the same time, the performance of the bag filter and the use of the effect has been greatly improved.

Dust collector's operation is economical and reliable; fault detection is accurate and convenient, and the maintenance is simple and convenient. This is the user's requirements, but also our goal. Over the past two years, through our unremitting efforts, has achieved some results, are summarized as follows:

Two, how to realize the fluid port isobaric spray nozzles blowing in nozzle on

The pulse valve of the injection flow into the nozzle at high speed, near the nozzle inlet when the maximum dynamic pressure, static pressure of the fluid in the nozzle at the bottom of the minimum, fluid dynamic pressure drop to zero, the static pressure reaches the maximum value. The fluid depends mainly on the static pressure from the nozzle into the bag. Adjust the injection tube on the nozzle aperture size is realized in different resistance, the fluid through the nozzle when the static pressure is equal. Which guarantees the consistent cleaning effect of the filter bag, the same life.

Handling the nozzle in the nozzle of the manufacturer, now most of the dust removal equipment are used as the pore structure, fluid pressure in the blowing nozzle of the spray is not the same, so the impact of differences in the bag, it will lead to excessive load from some bags, and shorten the life span. There are a number of dust removal equipment factory is the use of the nozzle aperture was reduced by the method, it is difficult to ensure that the nozzle orifice at the nozzle pressure is equal to the nozzle.

Injection pipe with nozzle structure can be adjusted through the activities of the test, pressure sensor, transmitter, oscilloscope and multiple detection, done during the cleaning fluid pressure is basically the same in the blowing nozzle spray, ensure the injection fluid on the impact of the basic bag, cleaning effect to achieve equal.
