BETE not only has one of the largest ranges of nozzles in the world but has an enviable reputation for fire protection, pollution control and flue gas desulphurisation.  The company also supplies Stang water cannons and monitors as well as a large range of hose reels for different applications.

Dust is a chronic problem at many stone or dirt quarries or mines. We offer dust control products that cater to conveyors, transfer stations, hoppers, crushers and unloaders. Below are common dust suppression nozzles:

Air atomising nozzles

XAAD-Low-Flow-Misting-and-Air-Atomising-Nozzles

These nozzles use a secondary fluid or gas to break up the primary spraying fluid into an exceptionally fine spray (atomisation).  The secondary fluid is usually air, but can be any gas, but the term “air atomising” is used for all.

Spiral full cone nozzles

A relatively small average droplet size can be achieved with the TF range of spiral nozzles. But within the mix of droplet sizes there exist some larger drops. These tend to concentrate in concentric rings of higher spray density.

Impingement misting nozzles

With this design of nozzle the fluid is ejected from the nozzle orifice and impacts upon a pin in the direct path of the water flow. This breaks up and disrupts the flow into a fine spray cone. As the fluid is being broken up by impact this allows for a larger orifice, thus allowing for more viscous or “dirty” fluids to be sprayed into a fog pattern.

More details

Wash applications rely on the impact of the spray to help dislodge residue. The full cone spray pattern nozzles distribute the kinetic energy of the fluid being sprayed over a large area and this reduces impact.  So in order to achieve the required impact other spray patterns are required. Typically a flat fan spray pattern will be used.  The problem is that this only cleans a thin line, so some kind of relative motion will be needed to clean a target area. This motion can be provided by a conveyor moving product under a cleaning spray bar or by a moving spray bar. Below are common washing nozzles for mining:

Deflector Flat Fan Nozzles for Cleaning

FF-Extra-Wide-Angle-Nozzles

The deflection type nozzle produces the flat fan pattern by deflecting the fluid stream against a curved surface after exit from the nozzle orifice.  The impact of the fluid on the deflection surface causes the desired atomisation and the geometry of the surface shapes the resulting spray into a flat fan pattern.

More details

Elliptical Orifice Flat Fan Nozzles

NF-1

With this design of nozzle the spray pattern is formed by the exit of the fluid through a shaped orifice.  This spray will be a high impact flat fan. These nozzles have a lower profile than their deflector design cousins and so may be more appropriate where space is confined.

There are stringent safety regulations in place to help mitigate this risk to life and property. It is useful to point out that the term fire protection refers to a system that is designed to protect an asset from the effects of fire as opposed to a fire extinguishing system that will help put our fires or a fire prevention system that helps stop fires from occurring in the first place. BETE produces a range of spiral nozzles (the N series) for fire protection systems. These combine fine droplets with the excellent spray reach and impact needed to work through the often strong thermal currents generated by fire. The combination of small and large droplets from these nozzles means the cooling power of small droplets can be delivered to fire by effectively being carried by the larger droplets. The N series of fire fighting nozzles have been approved by Lloyd’s, FM and UL. Below are common fire protection nozzles for mining:

Spiral nozzles for fire extinguishing systems

N Fire Protection Spiral Spray Nozzles

These nozzles produce a relatively fine spray with low medium droplet size. This gives them great cooling power. But the spectrum of droplet sizes is also larger than most nozzles. This makes them ideal for fire protection systems as the heavier droplets act to carry the smaller droplets to areas they would otherwise fail to reach. This is particularly important in fire protection systems as the air currents caused by heat may simply blow very fine droplets away before they can act on the fire.

Misting impingement nozzles for fire extinguishing systems

PJ-3

With this design of nozzle the fluid is ejected from the nozzle orifice and impacts upon a pin in the direct path of the water flow. This breaks up and disrupts the flow into a fine spray. This nozzle can produce the finest spray of any direct pressure nozzle making them suitable for many halon replacement fire extinguishing applications.

More details

Small orifice misting nozzles

MW

By forcing fluid through very small orifice at high pressure sufficient turbulence is created to atomise the spray into a fine fog. At lower pressures such a nozzle will form a mist. This makes these nozzles ideal for water misting fire extinguishing applications. As these nozzles work by having a very small orifice they are prone to clogging. Effective filtration is thus important. Bete’s MicroWhirl range of small orifice misting nozzles are a suitable choice for many halon replacement/ water misting fire extinguishing systems.

Our expertise extends to vehicle fire protection nozzles incorporating patented protective nozzle cap systems. Just like our range of ‘Blow-off’ cap nozzle series, the BM Foil nozzle is also designed with fire systems in mind. Below are common fire protection nozzles for mining:

BM nozzles

The BM spray nozzle range with patented rolled lip reduces internal vane dislodging from the nozzle body during handling and installation or due to thermal expansion. This technology coupled with the Patented BM14 protective dust caps with retention lanyards utilise an internal O-ring that retains itself on a standard non-modified BM Series nozzle.

BM foil series

BM-Foil-Family

With this design of nozzle the fluid is ejected from the nozzle orifice and impacts upon a pin in the direct path of the water flow. This breaks up and disrupts the flow into a fine spray. This nozzle can produce the finest spray of any direct pressure nozzle making them suitable for many halon replacement fire extinguishing applications.

BETE offers a wide variety of nozzles which can provide the low flow rates and fine atomisation required for humidification applications. This evaporation of fine water sprays can also reduce the temperature of the air, depending on the amount of water added and overall change in humidity.  Below are common humidification nozzles for mining:

The spraying of a fluid to cool gas, solids or even other fluids is a common industrial application. Cooling is achieved by spraying a cooler liquid that absorbs and carries away heat. Heat energy is transferred to the coolant either by warming it in its still liquid state or by evaporating/boiling the liquid into a gaseous state (phase change). Spray nozzles are used to cool a variety of processes in the Mining industry. 1) Cooling of gasses can be achieved by spraying a fine mist of coolant into the gas stream 2) The cooling of fluid beds 3)The cooling of reaction tanks. Below are common cooling and quenching nozzles for mining:

  • Eliminate Tank Entry
  • Clean any Tank regardless of residue
  • Clean 80% faster with less wastewater

Automated tank-cleaning programs can save time and labor when the solution is tailored to the cleaning environment

tank cleaning

What are the most important factors that make up an oil and gas industry tank or vessel cleaning program? It’s a succinct question and one that many contractors have never asked themselves. In many cases, tanks and vessels are cleaned when they’re no longer functional, using high pressure washing devices and brute human force supplied by workers who must often enter tanks to achieve acceptable results.

“To us, the most important factor in tank cleaning has nothing to do with cleaning the tank,” says Michael Delaney, vice president of business development with automated tank cleaning equipment manufacturer Gamajet. “It has to do with protecting workers and promoting their safety by eliminating the use of confined-space entry for cleaning, when that cleaning could easily be handled by an automated system.”

BeforeAftertrailerGamajet was founded about 60 years ago, offering a cleaning system that applied detergent to the insides of ocean-going oil tankers. About 20 years ago, the company diversified to cover tank cleaning in a number of industries, including oil and gas, using a wide range of cleaning systems and nozzles. The company’s approach to cleaning employs rotary impingement tank-cleaning machines.

Engineered tank cleaning

Each oil and gas tank cleaning application may be engineered differently, ranging from smaller totes, mud tanks and frac tanks to vacuum trucks, crude oil-carrying rail tank cars, transport tankers and larger refinery tanks.

liquid-transportTank owners first need to assess their needs and goals, whether worker safety, reduced labor cost, reduced use of cleaning fluids (either chemicals or water), reduced downtime for vessels and production equipment, the possibility of using tanks to hold more than one substance after cleaning and better tank performance. They next need to describe how the tank is currently cleaned and the type, size and interior layout of the tank.

 

Automated tank-cleaning programs can save time and labor when the solution is tailored to the cleaning environment.

sidewinder-2

Spray Nozzle Engineering and Gamajet have created a solution for cleaning the notoriously hard-to-reach bulkheads in cargo tank: The Sidewinder.

A revolutionary device for achieving the most effective tanker, trailer, and railcar cleaning, the Sidewinder enables a Gamajet Tank-cleaning device to be placed on its side, completely changing the nature of the nozzles’ orbit, enabling it to focus on the bulkheads. In effect, tankers can be cleaned in half the time.

Instead of following an ellipse pattern across the tank wall, as is the case when spinners are inserted vertically, the Sidewinder enables the machine to form a figure-8 pattern sweeping the length of the tanker. With the implementation of a Sidewinder, the spinner will deliver 30 times more hits to the bulkheads, cleaning tankers in half the time with no shadow areas, according to Gamajet officials.

Coupled with Gamajet spinners, which are designed to easily handle 6m to 9m throw lengths, the Sidewinder enables wash stations to provide the most efficient and effective clean to every inch of the tanker, giving you a Total Spraying Solution for the toughest application.
