Detailed Description

[0035] Referring to Figures 1 and 9, there is shown an transportable evaporation system 10 having a base 12, two evaporator units 14 supported by the base 12 and a pump and control system 15 carried by the base 12 intermediate the two evaporator units 14. The base 12 includes opposing ends 16 and opposing sides 18. The evaporator units 14 are supported toward each of the opposing ends 16 and the pump and control system 15 includes a pump 20 located intermediate the two evaporator units 14. It is noted that whilst in this example two evaporator units are preferably shown, it is contemplated that examples with a single evaporator unit or even several evaporator units may be provided in a similar manner to the evaporation system 10 disclosed herein.

[0036] Each of the evaporator units 14 includes a hollow cylindrical body 22 having an inlet end 24 and an outlet end 26, an axial fan 28 housed by the cylindrical body adapted to provide an airflow in a direction from the inlet end 24 toward the outlet end 26, and a water outlet 30, provided in the form of a ring with nozzles, located proximate the outlet end 26. Suitable evaporator units 14 may be adapted from that disclosed in AU 2012238201 and commercially available from Minetek™, although other suitable evaporators may also be used and the system 10 is not limited to any specific type of evaporator unit.

[0037] The system 10 is configurable between a transport configuration, as shown in Figures 6 to 11, in which each of the hollow cylindrical bodies 22 is arranged in a substantially horizontal lengthwise orientation relative to the base 12, and an installed configuration in which the hollow cylindrical bodies 22 are angled upwardly with the outlet ends 26 elevated relative to the inlet ends 24 as shown in Figures 1 to 4. In the installed configuration, both evaporator units 14 face away from the centre of the base 12 and are angled upwardly and oriented toward the same side of the base 12.

[0038] The base 12 may be part of or fit with a container such as a 40ft“flat-rack” container. In this example, the base 12 is formed from a 40ft“flat-rack” container. Accordingly, the base 12 may include a common skid 33 and end structures 34 at each of the opposing ends 16. In this example, the end structures 34 are a series of corner pillars 36 that form ends and bounds of the container. However, in other examples, end walls may be provided as well as sides and tops of the container.

[0039] The end structures 34 allow the evaporator assembly to be stackable in the transport configuration. The base 12 may be adapted to allow lifting of the entire system 10, and the underside of the base 12 may be adapted to allow sliding or“skid” movement on-site of the evaporator system 10. Further, in this example, the end structures 34 may also include supports or brackets 39 to hold sections 35 of an inlet pipe 60 that may be cut a length less than a length of the container. An intermediate support or bracket 41 may also be provided.

[0040] The opposing sides 18 may include couplings 40 to allow attachment with travelling straps (not shown) and/or removable side and end wall structures (not shown) to substantially enclose the evaporator assembly 10 in the travelling configuration. In the transport configuration, the evaporator units 14 are arranged to sit within the bounds or perimeter of the base 12 and lower than tops 43 of the end structures 34, as shown in Figure 6.

[0041] In the installed configuration, the hollow cylindrical bodies 22 are each supported by support stands 32 coupled to the base 12. The stands 32 are arranged to angle the hollow cylindrical bodies 22 upwardly and away from one another at an angle of about 45 degrees. In the transport configuration, the hollow cylindrical bodies 22 of the evaporator units 14 are supported by travelling support legs or stands 42 that support the hollow cylindrical bodies 22 in the horizontal and lengthwise orientation. Accordingly, to configure the evaporator assembly on-site to the installed configuration, the travelling supports 42 are replaced by the stands 32. In the transport configuration, it is noted that the stands 32 may be fitted under or alongside the hollow cylindrical bodies 22 in the transport configuration, and may be partially disassembled so as to be fitted accordingly.

[0042] The pump 20 may be supported on a pump skid 38 seated on the base 12. The pump skid 38 allows the pump 20 to be installed and removed from the base 12. Associated piping 44 includes split feed piping 43 between the pump 20 and each of the evaporator units 14 and an inlet 49 for the pump 20. The split feed piping 43 is fed by a single pump outlet pipe 41. The pump 20 may selectively feed one or both evaporator units 14 simultaneously. The pump 20 may be a self-priming pump long coupled 75lps l2bar commercial/y available from Pioneer™ with 400V 50Hz l60kW 2 Pole Electric motor.

[0043] The pump and control system 15 includes a motor control centre (MMC) 47 including controller 46 in communication with a motor 21 of the pump 20 and axial fans 28. The controller 46 and associated components may be housed by a cabinet 48 located adjacent the pump skid 38. The associated components may include, for example, 2 x 90kW starters, 1 x l60kW starter, and an E-stop. Each of the evaporators 14 also include a local control box 51 that may include an E-stop.

[0044] The pump skid 38, pump 20 and cabinet 48 may be covered by a canopy 50. The canopy 50 may be removable in the transport configuration and it may be bolted to the flat rack or to tapped pads on the flat rack. The canopy 50 may include lifting lugs, as required.

[0045] The pump and control system 15 may further include a pressure transmitter and flow transmitter 54 in communication with the MCC 47 fitted to the single pump outlet pipe 41. A single outlet isolation valve 56, such as a butterfly wafer valve, is provided. The pump and control system 15 is preferably fully wired with the MCC 47, axial fans 28 and pump motor 21 at the point of manufacture and prior to being shipped to site.

[0046] The evaporation system 10 may be manufactured in a modular sequence starting with the base 12 and then including the evaporator units 14 fitted on the travelling supports 42. The pump 20 may then be loaded onto the base 12 and the MCC cabinet 48 is installed. The remaining components of the pump and control system 15 may then be installed. The canopy 50 may then also be fitted. The inlet pipe 60 may be about 30 metres, or other suitable lengths. At site, the inlet pipe 60 is connected to the inlet 49 in use to draw water from an external body to be drain or evaporated into the pump 20 and the evaporation unit 14. The inlet pipe 60 may be provided in the sections 35 as detailed above.

[0047] A method of transporting and installing the evaporation system 10, includes, in the transport configuration, fitting two evaporator units 14 supported toward opposing ends 16 of the base 12 with the pump 20 of the pumping and control system 15 located between the two evaporator units 14. The two evaporator units 14 being arranged in a generally horizontal lengthwise orientation so as to fit within the bounds of the base 12 and end structures 34 thereof extending upwardly from the opposing ends 16 as best shown in Figure 6.

[0048] To reconfigure the system 10 to the installed configuration, the two evaporator units 14 are oriented so as to be angled upwardly and outwardly of the base 12. This includes removing the traveling supports 42 and refitting the two evaporator units 14 to installed stands 32. To remove the traveling supports 42 preferably a lifting apparatus such as a crane is used to lift the two evaporator units 14 and allow the traveling supports 42 to be removed and installed stands 32 fitted. The evaporator units 14 are then lowered onto the installed stands 32. The lifting apparatus used may the same lifting apparatus used to lift the system 10 from a truck as shown in Figures 10 and 11.

[0049] Advantageously, there has been described an evaporator system that provides a substantially self-contained unit that may be easily transported and configured for use on site. In particular, the evaporator system is provided with a common supporting base for both evaporation units and is preinstalled with the pump and control system that minimises earthworks, hydraulic and electrical installation on-site. Moreover, the evaporator system is configurable between a transport configuration that allows the system to fit substantially within the bounds of a 40ft flat-rack style container. The system is easily configurable to the installed condition once on site to upwardly and outwardly orient the evaporator units and connect the pump to the external water source to be drained via evaporation. The evaporator system may then be configured back to the transport configuration and moved to another location or site.
