Description

A kind of tower surface heat dump tube panel of vacuum heat-preserving
Technical field
The utility model belongs to solar light-heat power-generation technical field, and in particular to a kind of tower surface heat absorption of vacuum heat-preserving Device tube panel.
Background technology
At present, China is wideling popularize the utilization of the new energy such as solar energy, wind energy.Solar energy power generating and wind-force hair Electricity is influenceed the problem of intermittent and fluctuation all be present by weather, and solar light-heat power-generation is due to energy-storage system being present, thus Intermittence and the fluctuation sex chromosome mosaicism for solving photovoltaic generation and wind-power electricity generation are can be very good, stable, adjustable electricity is provided to power network Power exports.
At present, China in solar light-heat power-generation field also in the starting stage.Tower solar-thermal generating system is because thermal-arrest Temperature is higher, so the vapor (steam) temperature of conversion is also high, the transformation efficiency increase of steam turbine generator, the conversion effect of solar-thermal generating system Rate increase.Current tower heat absorber system is mainly spliced by heat dump tube panel.Low-temperature molten salt passes through on heat dump tube panel Endothermic tube absorb heat, reach the temperature of system requirements, convert solar energy into the heat energy of fused salt.But because composition is inhaled The endothermic tube of hot device tube panel is directly exposed in air, the thermal loss of two kinds of forms of heat radiation and heat transfer be present, in high temperature Under the conditions of endothermic tube thermal loss it is very big.
Utility model content
Deficiency, the utility model provide a kind of tower surface heat dump tube panel of vacuum heat-preserving for more than, effectively reduce The thermal loss of endothermic tube, add the photothermal conversion efficiency of collecting system.
The technical solution of the utility model is:
A kind of tower surface heat dump tube panel of vacuum heat-preserving, including endothermic tube and fused salt pipeline, the both ends of the endothermic tube It is fixedly connected respectively with upper and lower fused salt pipeline, glass tube is cased with outside the endothermic tube, the glass tube both ends passes through bellows It is connected and seals with endothermic tube, the glass tube is provided with bleeding point and valve, is vacuum between the endothermic tube and glass tube.
The bellows, valve and fused salt pipeline external are covered with protective cover.
The glass pipe surface is coated with anti-reflection film.
The endothermic tube is the metal alloy pipe of resistance to fused salt corrosion, and outer surface is coated with absorbing membranous layer.
The endothermic tube is divided into two rows, and interlaced arrangement in two rows.
The multiple tower surface heat dump tube panel serial or parallel connection composition collecting system of vacuum heat-preserving.
The utility model vacuumizes by glass tube in endothermic tube outer cover, and by space therebetween, reaches and outside The effect of air exclusion, greatly reduce the heat transfer with air under endothermic tube high temperature, the thermal loss of endothermic tube at high temperature By original thermal radiation loss and heat conduction loss, it is changed into mainly thermal radiation loss, the overall heat loss of endothermic tube substantially subtracts It is small, the photo-thermal efficiency increase of collecting system, and then increase the electricity conversion of tower photo-thermal power station.The utility model structure Simply, cost is low, is adapted to large-scale promotion application.

Embodiment
Design, concrete structure and caused technique effect of the present utility model are made furtherly below with reference to accompanying drawing It is bright, to be fully understood from the purpose of this utility model, feature and effect.
With reference to figure 1- Fig. 4, the tower surface heat dump tube panel of vacuum heat-preserving of the present utility model, including endothermic tube 1 and fused salt Pipeline 5, the both ends of endothermic tube 1 are welded and fixed with upper and lower fused salt pipeline 5 respectively to be connected, and glass tube 2, glass are cased with outside endothermic tube 1 Glass pipe 2 is provided with bleeding point and valve 4, and peripheral hardware air extractor is by bleeding point and valve 4, by between endothermic tube 1 and glass tube 2 It is evacuated, endothermic tube 1 and glass tube 2 constitute a sealing space, avoid endothermic tube 1 from directly being contacted with outside air, have Effect reduces the heat conduction loss of endothermic tube 1.When air extractor is evacuated, bleeding point and valve 4 are open mode;Remaining time, Bleeding point and valve 4 are closed mode, it is ensured that the space between endothermic tube 1 and glass tube 2 keeps vacuum.
The both ends of glass tube 2 are connected and sealed with endothermic tube 1 by bellows 3, and the effect of bellows 3 has two, first, real Existing interconnection between endothermic tube 1 and glass tube 2, second, the expansion system for solving the unlike material in temperature change mismatches The problem of, avoid because thermal expansion and contraction degree is different and caused by crack damage.In use, bellows 3, valve 4 and fused salt pipeline 5 Outside is covered with protective cover, prevents these parts from crossing cause thermal damage.
In order to increase the transmissivity of incident light, normal absorption of the endothermic tube 1 to solar energy optical-thermal, the table of glass tube 2 are not influenceed Face is coated with anti-reflection film, meanwhile, endothermic tube 1 is the metal alloy pipe of resistance to fused salt corrosion, and outer surface is coated with absorbing membranous layer;Endothermic tube 1 Be divided into two rows, and interlaced arrangement in two rows, it is ensured that incident light can full illumination to the absorption effect on tube panel, increased to incident light Rate.The endothermic tube 1 of diagram only draws 11 (front-seat 6, heel row 5), according to the design requirement of real system, endothermic tube 1 Quantity can be accordingly increased or reduced.
The tower surface heat dump tube panel serial or parallel connections composition collecting systems of multiple vacuum heat-preservings, during series connection, difference heat absorption The entrance of fused salt pipeline 5 between device tube panel interconnects with outlet.During work, fused salt pipeline 5 of the fused salt from bottom (or top) After being absorbed heat into endothermic tube 1, fused salt pipeline 5 of the fused salt again from top (or bottom) flows out.
Disclosed above is only embodiment of the present utility model, and still, the utility model is not limited to this, any ability What the technical staff in domain can think change should all fall into the scope of protection of the utility model.
