Episode 43 : DESIGN of Rotary Vacuum Drum Filter
Episode 43 : DESIGN of Rotary Vacuum Drum Filter
Theory of Separation
Rotary vacuum drum filter (RVDF) is one of the oldest filters used in the industrial liquid-solids separation .A rotary vacuum filter consists of a large rotating drum covered by a cloth. The drum is partially immersed in liquid/solids slurry with approximately up to (25-75) % of the screen area.
As the drum rotates into and out of the trough, the slurry is sucked on the surface of the cloth and rotated out of the liquid/solids suspension as a cake. When the cake is rotating out, it is dewatered in the drying zone. The cake is dry because the vacuum drum is continuously sucking the cake and taking the water out of it. At the final step of the separation, the cake is discharged as solids products and the drum rotates continuously to another separation cycle.

Types of air preheaters and its advantages
A very basic word to word meaning is a device used to heat the air before further use is called as Air Preheater. They are also recognized as air heaters or air-heating pipe. It is designed to exchange heat energy with desuperheaters. Desuperheater is a Device which is been used to reduce the temperature of the steam in a high heat generation plants where large amount of heat energy or steam is released in the atmosphere.
Surge in compressor
Surge is a phenomenon seen in gas turbine engines where there is a sudden decrease in the supply pressure to the compressor inlet. This causes air to flow in the reverse direction through the compressor, creating vibrations throughout the engine. Surge can be generated by diffuser vanes retarding the airflow or rotating stall causing breakdowns of the air flow between compressor blades. Repeated surging can damage components like rotor seals, bearings, and the compressor driver through high vibrations and temperature increases. Anti-surge systems aim to prevent surge by maintaining a minimum air flow through the compressor.

Baghouse Team
The document discusses particulate control and mercury removal technologies at a coal power plant. It considers three types of baghouse designs: shaker, reverse air, and pulse jet. Pulse jet is preferred due to increased filter bag life, lower maintenance costs, and ability to continuously clean bags. Mercury removal relies on installing SCR to oxidize mercury so it can be captured by the baghouse and wet scrubber. Adding powdered activated carbon is not needed if SCR oxidation and wet scrubber removal achieve over 90% mercury reduction. Annual operating costs for the pulse jet baghouse design are estimated to be $6.6 million per year.

Lecture3
Cyclones use centrifugal force from spinning gas to separate particulate matter. As gas enters the cyclone cylinder, it receives a rotating motion that develops centrifugal force pushing particles towards the wall. The gas then spirals down and reverses direction to exit through the outlet pipe. Particle collection efficiency depends on cut size, which is the diameter where 50% of particles are collected. Cut size can be estimated using gas properties, cyclone dimensions, and inlet velocity.
Cyclone resistant building design
This document discusses the design of cyclone resistant buildings. It first defines a cyclone as a low pressure system with inwardly rotating winds that can cause significant damage. Vulnerable structures are typically light wood frames or poorly constructed concrete blocks. During high winds, the suction on walls and roofs can effectively cause an explosion effect. The document then outlines various design considerations for cyclone resistant buildings, including choosing a sturdy site, reinforcing walls, designing strong roofs, properly placing windows, and using impact resistant materials.
ABS Air Tech presentation for hepa filters
HEPA filters can remove at least 99.97% of particles 0.3 micrometers or larger from air. They are constructed of borosilicate glass microfibers formed into pleated sheets separated by aluminum baffles within a framed filter. HEPA filters are classified by their efficiency in removing particles of different sizes and are critical components of laminar airflow cleanroom systems, which precisely control airflow to minimize particulate contamination. Proper handling and avoidance of moisture, heat, pressure, or chemicals is necessary to prevent damage to the delicate HEPA filter material.
Indoor air quality
Indoor air quality is influenced by emissions from building materials, products, combustion, and outdoor pollution infiltrating indoors. Common indoor pollutants can cause sick building syndrome symptoms. Passive sampling is a cost-effective technique for indoor air quality monitoring over long periods. Source control, ventilation, and air cleaning are strategies for reducing indoor pollutants, with source control being most effective. Air cleaners use mechanical filters, electronic methods, or ion generators to remove particulate and gaseous pollutants, with effectiveness depending on device efficiency and air flow rate. Activated carbon, zeolites, and chemisorbents can help filters remove gases and odors through adsorption and chemical reactions.

General Considerations for Operation
Face Velocity
Face velocity is the procedure whereby there is sufficient speed movement of air in the booth to enable it trap solvent emissions and particulate substances, therefore, is removed through the filters of a stack exhaust (Godish.,Davis., & Fu 2015). The face is referred to as the section whereby intake air goes in. The calculations of face velocity should consider the following:
1.0 The rate of make-up unit through which air run flows in cubic feet per minute.
2.0 The flow rate of exhaust fun in ft or cfm
3.0 The operation procedure entire opening section of the booth.
Calculations of either circular or rectangular opening are:
Circular
Area=
Rectangular
Area= Length x Width
A= 5m x 4m = 20m2
If the booth features numerous openings, the overall area will be derived by addition of each section. The air makeup flow rate and exhaust booth fun units will be subtracted:
Flow rate = exhaust fun flow = unit of air make up the flow rate
Thus, face velocity= total intake area/flow rate.
Filter velocity
Filter velocity can only be determined if slow-moving air is sufficient through filters in such a way that the drop of pressure is sustained and allowable in each filter, along with capturing particulate substances.
Method
To determine filter velocity, the calculation below must be made;
The exhaust fun flow rate in f3/min.
The booth filter area.
The booth including numerous filters will have its net area determined by the addition of areas of different booths Region (T. C. E. Q., Paso, E., Rubinstein, C., & Area, T. B., 2007).On the basis of the fact that the booth is comprised of the air makeup equipment and exhaust fun, the exhaust fun flow rate will be utilized as the net air that shifts into the booth will originate from the exhaust fan.
Flow rate = exhaust flow rate
Filter velocity= rate of flow/ total filter area
Thus, filter velocity = 15/20 = 0.75m3/s
VOC and ES Content per Vehicle
The calculations in this section are based.
Design and Fabrication of Economical Air Filter
The most general problem of todays environment is the presence of dust. The dust stability in air will lead to instability in human routine in the form of health disorders. The filtration of this kind of impurities from air is one of the best possible epidemiology and probably an economical and less expensive filtration system will further help to overcome this situation. The work in this project puts its concentration on the above mentioned factors. An air filter produced form the very often fetch of simple materials is designed, analyzed and fabricated. The trapezium modeled air filter with slots embedded in it, facilitate the fatigue replacement of materials after the expiry of the same. The incoming air is forced through an Exhaust fan for a faster movement of air rather than depending on the conventional method of air income. The air entering from the inlet gets protruded through different layers of filtration. The entire model, its analysis and results are discussed in the below work. Dr. B. Vijaya Kumar | M. Naveen | P.

Effect of plasma modification on comfort properties of blend fabric
In this dissertation, the effect of cold plasma treatment on the comfort properties of P/C blend fabric has been studied in a low pressure plasma reactor. The plasma treatment was conducted on the samples of 65% polyester and 35% cotton blend fabric using argon, oxygen and air, separately, as well as mixtures of O2/ HMDSO , N2/ HMDSO , H2O/ HMDSO and HMDSOmonomers alone as working gases. Special attention was given to oxygen plasma due to its wide application for various textile/polymer materials. Due to this reason, the Taguchi method was used to design, analyze and optimize the oxygen plasma process. Other plasma parameters including working pressure, discharge power, duration of treatment and flow rate were also considered. The various comfort properties of plasma treated and untreated P/C blend fabric have been studied. In particular, thermal comfort such as water vapor, air permeability, thermal resistance and wickability as well as tactile comfort including hand-feel and electro-physical properties were investigated. As the results showed that the oxygen plasma treatment had a positive effect on the thermal comfort and resistivity properties of P/C the blend fabric.
My published research paper
This document summarizes research on using a carbon dioxide laser to fade the color of cotton/kapok indigo denim fabric. Key findings include:
1) Laser treatment successfully faded the color of the cotton/kapok fabric, reducing the K/S value, while having little impact on thickness or permeability.
2) Tensile strength of the cotton/kapok fabric decreased with laser treatment, likely because the internal air of hollow kapok fibers was squeezed out.
3) Increasing laser power or decreasing speed led to greater reductions in both K/S values and strength, but negligible changes in thickness and permeability.

Schiffter aaps poster05
This study examined the drying kinetics of catalase protein solutions using acoustic levitation. Catalase droplets containing trehalose dried more slowly and formed denser particles compared to catalase-only droplets. Trehalose increased the residual enzyme activity of catalase to 95% while droplets dried at higher humidity showed lower activity. Acoustic levitation is a useful technique for studying single droplet drying kinetics but may not replicate conditions of spray drying.

Acoustic textiles (sound absorbing textile)
The document discusses acoustic textiles and summarizes:
1. Nonwovens are preferred for use as acoustic materials due to their porous structure, large surface area, and low production costs.
2. Sound absorption in fibrous materials occurs through frictional losses as sound pressure causes air molecules to oscillate within material interstices, and through momentum and temperature fluctuation losses.
3. A fabric's sound transmission loss increases with frequency, weight per unit area, and air resistance, but decreases with thickness and fiber density. Fabric microstructure also influences transmission loss.
