Visualized 3D model for design verification and optimization
3D modeling can provide intuitive intermediate connection structure, ensure the equipment accurate manufacturing and at the same time provide the packaging model with packing list which is helpful to control transportation cost.
Modular design can handle with various gas volume by different arrangement and combination
For high temperature long bag pulse bag house, the filtration area as 3840~25440m² and gas disposal volume as 196000~1030000m3 .
For low voltage long bag pulse bag house, the filtration area as 1060~27840m² and gas disposal volume as 11000~2000000m3 .
Advanced design technology to ensure uniform air distribution
CETEC can analyze physical capability of each system, optimize the fluid dynamics and study the efficiency of pollution removal by Ansys Fluent and CFD software. Based on the analysis to adjust inlet duct location, deflector and duct baffle to get optimal air distribution and reduce air speed.
The offline pulse cleaning effect is more thorough and maintenance can be carried out online. The large volume bag house is generally designed as an offline structure and has two dust cleaning functions that can be switched offline and online depending on the working conditions. No matter whether online or offline dust cleaning is chosen, it will not affect the operation of the bag house.
 Erection of bag house
from bottom to up. |  Ensuring hopper
and chamber welding no leakage by strict leakage detection measures. |
 Checking and
cleaning the impurities and iron filings in the gas path before the
installation of the injection system. |  At the same time of
ensuring the same distance between the spout and the tubeplate, the spout
and the bag mouth should be concentric. |
 The filter bag
shall not be scratched by hard objects and the mouth of the bag shall be
pinched into a concave shape, so that it can be fully embedded with the tubeplate. |  Inserting the
bag cages into the filter bags gently to avoid scratching the filter bag until
the cover is pressed on the cell. |
 Fluorescent powder
leakage detection is the key method to check whether there is a leak point,
ensure good sealing and low emission concentration. |  In order to
prevent water vapor from condensing and dust from pasting the bags, the external insulation
layer should be added to ensure that the gas temperature is 25~35℃ higher than
the dew point. |
