How to do with moisture in the Air flow of Dust removal system?
Aug 23, 2018

The moisture in dust airflow in dust precipitator may cause serious problems in our dust removal system, including shortening the service life of filter and dust accumulation, resulting in system component failure or dust accumulation in dust funnel.


In addition, these and other complications caused by moisture will reduce the performance of the dust removal system, thereby increasing the operating cost of the system and affecting the quality of the product.


When warm, humid (humid) air in the atmosphere cools, the moisture condenses to form Rain Water. The same thing can happen in our dust removal system. During warm and humid processes, empty air cools as it flows through the duct system of the dust removal system, causing water to condense into liquid water droplets.


If dust absorbs moisture, it absorbs water and forms sludge that accumulates on the inner surface of the system. This accumulation may cause the ash hopper to fail to discharge normally, and the blade of the hopper rotary gas gate valve to jam. Dust accumulates on the pressure sensor, resulting in the wrong pressure reading, and the dust attached to the inner surface of the pipe. Make pipeline weight and pipe diameter smaller, may lead to pipe failure.


Sludge also accumulates on the surface of the filter, increasing the pressure loss of the filter and reducing the efficiency of reverse pulse injection or mechanical oscillator cleaning. Moisture weakens the filter medium, causing the filter to leak or malfunction, and allowing dust to pass through the filter. Moisture can also reduce the amount of dust recovered to product quality standards. These questions can increase operating costs by reducing productivity, shortening the service life of filters, causing maintenance problems, and leading to unstable and unreliable system performance. Moisture in the dust removal system can cause problems, even if it does not cause dew. In vapor form, moisture is less dense than dry air. If our system components operate under false conditions of dry airflow without moisture, but our actual airflow contains moisture, the airflow through our system will be higher than the rating. This results in increased energy costs for running system fans at higher speeds, shorter filter life, unstable system equipment and poor performance, all of which have a negative impact on our operations.
