Using just a few parts per million of the drag reducer helps to reduce the turbulence inside the pipe. Because the oil pushes up against the inside wall of the pipe, the pipe pushes the oil back down causing a swirling of turbulence to occur which creates a drag force. When the polymer is added, it interacts with the oil and the wall to help ...
A dust collector is a system used to enhance the quality of air released from industrial and commercial processes by collecting dust and other impurities from air or gas. Designed to handle high-volume dust loads, a dust collector system consists of a blower, dust filter, a filter-cleaning system, and a dust receptacle or dust removal system.
Eccentric reducers are used at the suction side of pumps to ensure air does not accumulate in the pipe. The gradual accumulation of air in a concentric reducer could result in a large bubble that could eventually cause the pump to stall or cause cavitation when drawn into the pump. Eccentric reducers exhibit a unique design with one side having ...
Water is the most common solvent used to remove inorganic contaminants, particularly for dust, but solutions of reagents that specifically target certain compounds may also be used. [4] Process exhaust gas can also contain water-soluble toxic and/or corrosive gases like hydrochloric acid (HCl) or ammonia (NH 3). These can be removed very well ...
A high concentration of dust is in the inlet stream; The dust is sticky or has a tendency to plug openings; The gaseous contaminant is very soluble or chemically reactive with the liquid; To maximize the absorption of gases, venturis are designed to operate at a different set of conditions from those used to collect particles.
Cement, lime and lead industry accepted dust loads (for structural loading) are: Process ductwork is intended to convey large volumes of dust. some of this dust will settle to the bottom of the duct during power outages and normal operation. The percentage of duct cross section filled with dust is often assumed to be as follows:
A copper concentric reducer. A concentric reducer is used to join pipe sections or tube sections on the same axis. [1] The concentric reducer is cone-shaped, and is used when there is a shift in diameter between pipes. [1] For example, when a 1" pipe transitions into a 3/4" pipe and the top or bottom of the pipe doesn't need to remain level. [2]
These two factors result in better separation of dust particulates. The pressure drop of multiple-cyclone separators collectors is higher than that of single-cyclone separators, requiring more energy to clean the same amount of air. A single-chamber cyclone separator of the same volume is more economical, but doesn't remove as much dust.
