Industry status and problems (flue gas system)

After 30 years of development and exploration of waste incineration, the entire technological process, including the major unit equipment and local systems, has reached the foremost level. Among them, the flue gas system process is as follows:

Waste power generation: In 2017, 70% of the 359 operating waste incineration plants did not disclose monitoring data, especially dust particles (the above data)

Analysis of the current status of filter bags: PTFE membrane filter bags have become a must for waste incineration and hazardous waste disposal industry for ultra-low emission of dust particles, but there are still a series of problems

PTFE fibers are uneven
Backward production equipment
Strict quality control
Lack of post-service process

Precautions

华滤环保
1. Dust leakage at the mouth of the filter bag
The head support of the filter bag has not been reset, the naked eye feels that it has been reset, but there is actually a gap;
2. The filter bag falls
The misalignment of the bag head makes the filter bag lose the supporting force of the flower plate to the filter bag. During the operation, it is dropped by the pneumatic blow of compressed air;

Supplementary points

  • Correct the demonstration picture, the PTFE membrane filter bag must use a protective sleeve and the installer must wear soft fabric gloves for installation;
  • The stitches are facing away from the air inlet;
  • Do not use heavy objects or metal objects to strike the head of the filter bag;
  • Set cages must be handled lightly, with a little rotation when placed;
  • After the installation is completed, use the packaging carton to lay the cover to avoid deforming the lead by foot;

Proper use of PTFE filter bags

PTFE membrane caused by incomplete combustion of start-up fuel and inadequate pre-spraying;
Circumvention measures
Start the furnace and borrow the debugging filter bag;
Increase the amount of slaked lime during the start-up phase;
