The dust problem of environmental protection in concrete mixing plant

1. Correct design, layout and reasonable selection of dust removal equipment. Install the dust collector directly on the head cover of the inclined belt. All the induced air ducts are also connected to the inclined belt hood, which provides a space for the dust blown off by the induced air ducts to settle, and is effective in reducing the amount of dust directly entering the dust collector. Then install a pneumatic butterfly valve automatically controlled by the mixing station operating system at the lower mouth of the dust collecting hopper of the dust collector.

  2. The dust removal equipment should be carefully inspected and maintained. The control of the dust removal vibrator of the silo dust collector is very important, but the majority of concrete mixing plant customers often do not realize its importance. When the dust removal effect is found to be poor and the safety relief valve starts to emit dust, the dust collector has already It is full of dust, and then I want to start the vibrator to remove the dust on the filter element. It is often too late and does not work at all. Therefore, each shift must be checked for dust accumulation in each dust removal pipe, because the non-vertical dust removal pipe is easy to block. It is necessary to check the dust accumulation of the filter elements of each dust collector regularly, and if necessary, disassemble, clean and clean the filter elements.

   The correct and reasonable design, layout and selection of dust removal equipment can not only ensure the overall quality of the mixing plant, but also have important meanings for reducing the cost of use and maintenance.
