an agitator is a device or mechanism to put something into motion by shaking or stirring.there are several types of agitation machines, including washing machine agitators which rotate back and forth and magnetic agitators which contain a magnetic bar rotating in a magnetic field .
in chemical engineering, a jacketed vessel is a container that is designed for controlling temperature of its contents, by using a cooling or heating 'jacket' around the vessel through which a cooling or heating fluid is circulated.. a jacket is a cavity external to the vessel that permits the uniform exchange of heat between the fluid circulating in it and the walls of the vessel.
high-shear powder induction systems also offer easy interchangeability with multiple tanks. high-shear granulators. a high-shear granulator is a process array consisting of an inline or batch high-shear mixer and a fluid-bed dryer. in a granulation process, only the solid component of the mixture is required.
agitation is further assisted by the use of tank baffles to increase the efficiency of agitation and prevent centrifuging of slurries in circular tanks. extraction efficiency factors. aside from chemical requirements several key factors influence extraction efficiency: retention time - refers to the time spent in the leaching system by the solids. this is calculated as the total volumetric capacity of the leach tank/s divided by the volumetric throughput of the solid/liquid slurry.
a chemical reactor is an enclosed volume in which a chemical reaction takes place. in chemical engineering, it is generally understood to be a process vessel used to carry out a chemical reaction, which is one of the classic unit operations in chemical process analysis. the design of a chemical reactor deals with multiple aspects of chemical engineering.
economy favors using small tanks; but if flow rate through the tank is too high, most particles will not have sufficient time to settle, and will be carried with the treated water. considerable attention is focused on reducing water inlet and outlet velocities to minimize turbulence and promote effective settling throughout available tank volume.
if the operating conditions are under high pressure or high temperature, the agitator must be equipped with a sealing system to keep tightened the inside of the tank when the shaft is crossing it. if the shaft is long > 10m , it can be guided by a bearing located in the bottom of the tank bottom bearing .
hybrids also share additional traits with tank-type heaters like a floor-standing installation, standard pvc venting, draining pan, and they can be installed with a recirculation pump for even more water efficiency. during high demand, high-flow situations, hybrid technology behaves more like a tankless heater, with high heating capacity and .
this type of aeration has a very high oxygen transfer efficiency ote , sometimes as high as 15 pounds of oxygen / horsepower * hour 9.1 kilograms of oxygen / kilowatt * hour . on average, diffused air aeration diffuses approximately 2–4 cfm cubic feet of air per minute 56.6-113.3 liters of air per minute , but some operate at levels as low as 1 cfm 28.3 l/min or as high as 10 cfm 283 l/min .
ultrasonic cleaning uses cavitation bubbles induced by high frequency pressure sound waves to agitate a liquid. the agitation produces high forces on contaminants adhering to substrates like metals, plastics, glass, rubber, and ceramics. this action also penetrates blind holes, cracks, and recesses. the intention is to thoroughly remove all .
use of any other kind of detergent in a high-efficiency washer can confuse your washer cycle and stop the machine -- and it can prevent it from washing or rinsing properly. fortunately, prices are .
draft tube is a diverging tube fitted at the exit of runner of turbine and used to utilize the kinetic energy available with water at the exit of runner. '. this draft tube at the end of the turbine increases the pressure of the exiting fluid at the expense of its velocity. this means that the turbine can reduce pressure to a higher extent .
high-efficiency top-loaders with a wash plate instead of an agitator can spin up to 1100 rpm, as their center of gravity is lower. higher spin speeds, along with the diameter of the drum, determine the g-force, and a higher g-force removes more residual water, making clothes dry faster.
coarse bubble diffusers produce 1/4 to 1/2 inch 6.4 to 13 mm bubbles which rise rapidly from the floor of a wastewater treatment plant or sewage treatment plant tank. they are typically used in grit chambers, equalization basins, chlorine contact tanks, and aerobic digesters, and sometimes also in aeration tanks. generally they are better at .
agitator turning thanks to gas; the choice of the agitator depends on the phase that needs to be mixed one or several phases : liquids only, liquid and solid, liquid and gas or liquid with solids and gas. depending on the type of phase and viscosity of the bulk, the agitator can be named mixer, kneader, dough mixer, amongst others. the agitators use in liquids can be placed on the top of the tank on vertical position, or horizontally on the side of the tank or less common, agitator is .
the process proved successful at their central block plant, broken hill that year. significant in their 'agitation froth flotation' process was the use of less than 1% oil and an agitation step that created small bubbles, which provided more surface to capture the metal and float into to a froth at the surface.
the continuous stirred-tank reactor cstr , also known as vat- or backmix reactor, or a continuous-flow stirred-tank reactor cfstr , is a common model for a chemical reactor in chemical engineering and environmental engineering.a cstr often refers to a model used to estimate the key unit operation variables when using a continuous agitated-tank reactor to reach a specified output.
general structure of a continuous stirred-tank type bioreactor a bioreactor refers to any manufactured device or system that supports a biologically active environment. 1 in one case, a bioreactor is a vessel in which a chemical process is carried out which involves organisms or biochemically active substances derived from such organisms.
overdosage leads to drowsiness, agitation, nausea and anticholinergic effects like tachycardia high heart rate , dry mouth, blurred vision, glaucoma, or urinary retention. especially in children, pentoxyverine can cause hypoventilation, but much more seldom than codeine and other opioid antitussives.
