Introduction to Lime types and Slurry preparation Design considerations for storing feeding and flow promotion of dry.
. Kpro K and HD are all designed with their suction on the side of the pump and with the. Special considerations relevant to this systems are introduced by the fact that slurry in not homogeneous phase unlike gas or liquid. The design of biogas digesters demands engineering expertise.
Lime Slurry - Up to 150 PSIG. Fiberglass can be used in abrasive and corrosive applications but it can also be used to create custom parts to fit almost any need. PO Box 536 730 Superior St Building 16 Carnegie PA 15106.
A suspension of solid particles in a liquid as in a mixture of cement clay coal dust manure meat etc. The half pipe was run over the sedientation tank. Abrasion resistant fiberglass pipe was chosen to move the limestone slurry within the system.
Mechanically the design of the lime-slurry spraying equipment is important. Inlet Design Hints 1. In transport systems for slurries its important to avoid settling of solids by keeping the fluid velocities in the pipe lines.
On-site preparation of high-density slurry concentrations ranging from 32-38 eliminates the need for costly delivery of lime in slurry form HDL Slurry remains in suspension drastically reducing scaling build-up in pipe and equipment HDL reduces operator maintenance and equipment downtime. - with water is often called a slurry. 22001 Piping systems are not subject to the approval of TSSA Boilers and Pressure Vessels Safety Division.
The limestone is abrasive and requires an abrasive resistant piping system. Classes of Construction see Standard Specification Section 225 1. Lime slurry can be an unforgiving material to pump because it is inherently abrasive corrosive has high particulate and high viscosity.
Maintain the inlet line in as straight a run of piping as possible. Scaling of the pipe lines troughs slakers etc. Chemco hydrated lime systems are able to produce a range of lime slurry concentrations from 5 concentration up to a high density concentration greater than 375 to meet the application requirements as well as the customers expectations for functionality and operability.
Browse Our Slurry Pumps Contact Us For a Quick Quote. Design the inlet piping to be as short as possible between the sump and pump. The lime changes its state to a solid mass of material commonly referred to as scaling.
Class A- Used for extremely poor soils PI 45 to 50. Wilfley Kpro K and HD slurry pumps are very commonly used in lime slurry applications. This Manual sets out the basic principles and gives a good appreciation of the technology.
I have also seen a half pipe PVC_U used in a gravity situation. The EDDY Slurry Pump was designed to excel in the harshest applications and makes it a superior. Flow velocities in slurry transport systems to avoid settling of solids.
Reduces cost of lime supply. Any design should assume that and provide for back-flushing of the nozzle or dilution of the slurry by having a side port where liquid from the top of the tank can be injected into the nozzle. Slurry piping system like any other system consists of slurry pumps pipelines and valves.
A straight line from tank to. Lime is applied in 2 applications. Lime slurry would be one of the most difficult fluids to work with.
We worked with Westar Energy to identify problem. One of the many advantages of working with fiberglass is its versatility. This was for lime dosing in a sewage treatment plant.
Material buildup on valve seats and other surfaces can cause the valves to freeze in position. One advantage of the process is the lack of serious material corrosion problems. Lime slurry is a stable suspension and is not corrosive once the slurry has been stabilized by allowing all of the water to fully react with the calcium hydroxide usually about 15 minutes minimumThe dissolved solids from the dilution water will precipitate if injected before stabilization on piping and injectors and form scale.
Transportation of bulk materials in the form of a slurry through piping systems is a most efficient and effective mechanism. In order to replace the worn elbows. The factors decisive for design are too complex to be expressed in simple up-scaling tables.
The lime slurry is hauled to the roadway and placed via special slurry tanks with agitators to keep the lime in suspension during transport and placement. Tubular Bag Separator 23. A rotating atomiser is used situated in the top of the spray-dry chamber.
Tomato juice is 180 cps Size metering pumps with a 301 turn-down. Probes used for level control in the slurry tank are often coated with lime solids and rendered ineffective. Scaling of the pipe lines.
After some time in operation it was determined that there were areas of high wear in one of the 8 inch fiberglass pipe lines at some of the elbow locations. Design Conditions 150 PSIG 149oF Operating Conditions Atmospheric - 125 PSIG 110oF Design Fabrication Installation Approval Requirements ASME B311 Power Piping OReg. Lime Slaker and Lime Slurry Tank 20.
Scaling causes a pipelines inner diameter to become smaller and smaller. Lime Slurry Piping Reduces Westar Plant Downtime July 9 2013 in Blog by theVR. Every change of direction adds friction losses to the flow.
Construction must be carried out by qualified masons. Lime Slurrying A severe problem of abrasion occurs if fiber rein- forced plastic FRP tanks are used for slurry pre- paration. Size slurry piping with a min velocity of.
Lime Slurry Feed Pumps Quantity 3 21. Their unique design makes them almost perfect for this duty but care must be taken in the inlet design to ensure proper operation. Air Compressor This project consists of replacement ofthe following equipment.
Vacuum Cleaner System 22. If this wears or suffers blockage the spray pattern is affected which reduces further the desulphurisation efficiency. Specifics - High density lime 35 35 slurry acts as a pseudo plastic and will not settle or scale pipelines 35 slurry has a viscosity of 200 cps.
Slurry can be described as liquid with solids suspended therein. Tanks made of corrosion resistant metal should be used to avoid abrasion problems. The financial ramifications of improper valve instrumentation and piping selection for processes such as lime slurry can have a long-term negative impact on most operations.
Training for design and construction of. Specialized valves can minimize the buildup in the nozzle but aren t foolproof. Plate and Frame Press with a Belt Filter Press or Centrifuge to be confirmed by Consultant during preliminary design 2.
