I. Background: According to our technical staff on-site investigation cases, your existing blasting machine dust removal system can not meet the requirements, affecting the normal blasting operations, back gray phenomenon equipment operation, affecting the shop floor environment. Existing dedusting system is actually a simple ventilation system, there are many design problem of irrational, can not solve the dust problem. Second, the governance program: 1, for analysis of dust: dust, sand blasting machine shop mainly for devices attached above the dust, is at room temperature, non-corrosive dust, moisture-free, so the dust control belong easy cleaning dust. Xu Yang Albert recommends: Use Shanghai Borg company's polyester + PTFE membrane filter media, the filter has wear, oxidation, easy cleaning and long service life. 2, the cleaning system design: pulse jet can more effectively remove dust attached to the surface of the bag, the kinetic energy of the pulse airflow blowing big, thorough cleaning. I designed the pulse dust skeleton additional venturi orifice can induce several times in the compressed air flow naturally into the bag, so that the bag walls get high reverse acceleration to completely clean off the dust. Electromagnetic pulse valve is a key component of the entire injection system, played a crucial role in the long-term functioning of the device. Xu Yang Albert recommends: Use Shanghai bag (Shanghai Carbon Works joint venture with the United States Al Gore brand) produced DMF-Z-25 rectangular electromagnetic pulse valve. DMC-120 stand-alone pulse bag filter 3, equipment selection: The blasting machine exhaust gas volume I chose to run a stable, mature technology for DMC-120 type pulse bag filter, the filter for small stand-alone bag-type dust collector, dust collection system with external filter type, the use of high pressure (0.5-0.7Mpa) pulse-jet technology, with cleaning kinetic energy, high cleaning efficiency. 4, pipeline installation: combine your company's actual production, in order to shorten installation period, I will be both indoor and outdoor piping design component section flange connections for easy installation and maintenance, while reducing installation period, the normal production and the impact on your company's small. http://www.jinxuhb.com/djccq/2015/0307/152.html
