PURE-AIR will give you a detailed introduction to the dust explosion accident in Kunshan City that has been heard for a while, and analyze to large enterprises why it is necessary to install an explosion-proof dust collector to remove dust, and a laser air filter!

On August 2, 2014, a heavy aluminum dust explosion occurred in the second grinding and polishing workshop of Suzhou Kunshan Zhongrong Metal Manufacturing Co., Ltd., which caused 75 deaths, 185 injuries and property losses of 350 million yuan on the same day. The subjective cause of this accident was that the dust removal equipment in the workshop where the accident occurred was not removed in accordance with regulations for a long time, and aluminum dust accumulated. After the centrifugal fan of the dust removal equipment is turned on, the high-temperature particles formed during the whole process of polishing and polishing will produce dust clouds on the top of the laser air filter mini for fume barrel. Because there is no explosion venting equipment, the high-temperature steam and combustion products caused by the explosion are sprayed out from the dust removal outlets through the ash removal pipeline in an instant, causing the actual operating staff of all stations in the whole workshop to be immediately exposed to explosive shocks, resulting in extreme safety accident.

The company did not deal with long-term deficiencies and potential safety hazards, which caused the dust concentration value to exceed the standard, and an explosion occurred when it encountered an ignition source. The company's industrial plant did not develop and build infrastructure as a Class II hazardous material site, and violated the regulations on the two-story design plan to build a production and manufacturing workshop, and the building spacing was insufficient. The production process is too tight and too dense. There are 29 production lines and more than 300 workstations in the 2000 square meter workshop. The ash removal capacity is insufficient, and no separate dust collection equipment is designed for each position as required. All electrical equipment in the workshop is not equipped in accordance with the fire protection regulations. 

The production safety rules and regulations and countermeasures are not complete and not implemented, and the pipeline dust is not removed on time for each shift as required, which leads to excessive dust accumulation; no safety education and training for employees, and no flame-retardant and anti-static configuration are required. Labor protection supplies; violations of labor laws and regulations, requests to work overtime, many unsafe factors have planted major safety hazards for this accident, and accidents are inadvertent, and accidents are inevitable.

Even the medium and large intermediate explosion-proof dust collector equipment of supporting facilities may accumulate dust due to lack of maintenance and eventually cause large and medium-sized accidents. The explosion-proof dust collector with PURE-AIR technology removes dust, laser air filtration is exquisite and has a small footprint and clear boundaries, which can be trusted!
