Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in detail.Following example will assist in the technology of this areaPersonnel are further appreciated by the present invention, but limit the present invention the most in any form.It should be pointed out that, the ordinary skill to this areaFor personnel, without departing from the inventive concept of the premise, it is also possible to make some deformation and improvement.These broadly fall into the present inventionProtection domain.
Embodiment 1
As it can be seen, boats and ships solar seawater desalination TRT, including thermal-arrest frame 3, add hot tank 13 and fresh water collecting case 19,Uniform on described thermal-arrest frame 3 parabolic lens 6 is installed；Thermal-collecting tube 5 is arranged on above parabolic lens 6, and its two ends connect drawing liquid pump 1,Described drawing liquid pump 1 quantity is 2, and connecting between the two has through the described circulating line 10 adding hot tank 13.The outside peace of drawing liquid pump 1Equipped with regulating gate 2, parabolic lens 6 is circular arc, and multiple parabolic lens 6 are installed by collection sheet 9 and are integrated to form circular arc, and pass through spiral shellNail 8 is connected fixing with collection sheet 9 locking, and parabolic lens 6 two ends are laid with hole 7, location by axle center, are used for regulating thermal-collecting tube 5 deviation angleDegree.
Add hot tank 13 inner top and the cloth 14 that catchments be installed, fresh water collecting pipe 21 be arranged on described in catchment below cloth 14, describedFresh water collecting pipe 21 has water delivery bar 18 with catchmenting uniform connection between cloth 14, catchments cloth 14 and water delivery bar 18 material is nylon, lightThe uniform circular hole that offers on water collection pipe 21, it is internal that the end that drips of water delivery bar 18 extends to fresh water collecting pipe 21 through circular hole, instituteState fresh water collecting pipe 21 to connect with drain pipe 12；Drain pipe 12 preferentially uses aluminum pipe, and the cloth 14 that catchments is high to by-level from four limitsDegree is gradually lowered, and fresh water collecting pipe 21 tilts from centre to both sides, water delivery bar 18 length different, from both sides to middle lengthShorter and shorter.Described circulating line 10 is provided with lateral 40 adding inside hot tank 13, described lateral 40 is uniform to be connected toThe top of circulating line 10, circulating line 10 and lateral 40 preferentially use copper pipe.Also set below described fresh water collecting pipe 21Having drainage screen 41, filter material is nylon；Drainage screen 41 is buckled in by fastener and adds hot tank 13 inside.
Drain pipe 12 is connected with fresh water collecting case 19, and water-delivery pump 15 is arranged on and adds in hot tank 13, water-delivery pump 15 and heatingConnect between case 13 and have supply channel, described in add liquidometer 11 be installed in hot tank 13, connect between water-delivery pump 15 and liquidometer 11Being connected to signal transmssion line, outlet pipe 20 is connected to below fresh water collecting case 19.Also including signal projector 16, described signal is launchedSignal line group it is respectively connected with between device 16 and water-delivery pump 15 and liquidometer 11.Described liquidometer 11 is electronic liquid level gauge.It addition,Also being provided with liquidometer on fresh water collecting case 19, being connected between liquidometer with signal projector 16 has signal transmission line.
Adding hot tank 13 and be also associated with appendix 42, described appendix 42 gas outlet connects steam turbine 48, electromotor 49Rotary shaft is connected with steam turbine 48.Steam turbine 48 drives electromotor 49 to generate electricity by the promotion of steam, sets bottom steam turbine 48Having coagulator 46, water-supply-pipe 45 to be connected to coagulator 46 one end, it is arranged above with water pump 3 44.The other end of coagulator 46 is evenIt is connected to hydrops drain 47, is condensed device 46 bottom entrance steam turbine 48 after Steam Actuation steam turbine 48 generating and condenses into water,Got rid of by hydrops drain 47.Described electromotor 49 side is provided with power distribution cabinet 50, and accumulator battery 51 is arranged on power distribution cabinet 50In, electromotor 49 is connected with power distribution cabinet 50 transmission line of electricity group.Accumulator battery 51 stores electric energy for external electric equipment.
This boats and ships solar seawater desalination TRT disclosed by the invention, operation principle is such, the most logicalCrossing water-delivery pump 15 and carry sea water within adding hot tank 13, water-delivery pump 15 controls motor for PLC, and the automatic sensed water level of liquidometer 11 is highSpend, and the moment sends information to water-delivery pump 15.Being marked with conduction oil in thermal-collecting tube 5, the heat of solar energy is concentrated by parabolic lens 6 simultaneouslyHeating conduction oil on thermal-collecting tube 5, conduction oil is the highest is heated to 400 degrees Celsius, and drawing liquid pump 1 is by the conduction oil of heatingSending in circulating line 10, it is heating of seawater that such conduction oil enters in adding hot tank 13 so that it is boiling produces steam.
Steam moves upward and condenses on the cloth 14 that catchments and forms fresh water, due to the cloth 14 that catchments from four limits to by-levelHighly being gradually lowered, by action of gravity, The natural flow of water always proceeds from a higher level to a lower one goes, and water lowers into fresh water along water delivery bar 18 in flow processEntering in collecting pipe 21 in drain pipe 12, fresh water is assembled, if desired in entering fresh water collecting case 19 eventually through drain pipe 12 againUsing fresh water, discharged by outlet pipe 20, outlet pipe 20 is installed above a hand door, controlled makes water size.
