Description
The invention belongs to a kind of Application of Solar Energy technology.
At present, in the bituminous paving of highway was built, the intensification dewatering process of pitch mostly adopted fuel naked light or steam-heated mode, this mode energy consumption is big, and the thermal efficiency is low, and labor strength is big, environment and air pollution are serious, and because the pitch flashing point is low, breaking out of fire easily.
Middle nineteen seventies adopted the spray burning method once, and Yin Wendu is too high and cause the physical property of pitch to change and increase iron and steel consumption and promoted and use.In recent years, our province utilizes approximate this character of black matrix of greenhouse effects principle and pitch when sun, Qianjiang, the sunray in the Asphalt Absorption certain limit and temperature raises, but maximum temperature can not break through 100 ℃ and do not reach requirement of engineering.
The purpose of this invention is to provide the multimode solar heat collector of a kind of segmentation, with the intensification of satisfying pitch, the process that dehydration requires.
Solar energy is a kind of low-density energy, uses the room temperature effect principle, pitch can only be heated to fluidised form, therefore with greenhouse (1) as the first order of the present invention.For making pitch utilize solar energy further to be warming up to more than 100 ℃, just must improve the heat flow density of solar energy, increase the focusing ratio.Select for use the two-dimension focusing system can satisfy this requirement, and simple, easy from motion tracking.
Caustic surface is made into column type parabola (8), and caustic surface should be a minute surface, and this minute surface is to realize with the vacuum aluminum-coated mylar of high reflectance again on caustic surface.The cross section of column type parabola (8) is a parabola.This parabolical perifocus also is its center of gravity, the light that is incident on the column type parabola is converged to a focal line, adorn a metallic conduit (9) along focal line, fuse with the parabolic framework of column type, when fluidised form pitch passes through pipeline (9), by the heating that heats up, this root metallic conduit (9) also is the trunnion shaft of column type parabola (8), can rotate around it, make caustic surface by the hour angle of photo-electric control, when the installation key is whole, make focal line be parallel to earth's axis from the motion tracking sun, adjust stringing mechanism (14) and make caustic surface aim at the one dimension position of the sun, another dimension position then is caustic surface is followed the tracks of the sun according to turning cylinder a hour angle.
In the west side of caustic surface, be furnished with suitable weight (7) and tension spring (13), rotate along focal line as caustic surface, photo-electric control is from the power of motion tracking solar hour angle.Its principle is: braked wheel (11) and brake band (10) are housed on collector metal pipe (9), brake band (10) is connected with tractive magnet (12), electromagnet (12) is subjected to the control of automatic control output signal, and the frictional force between braked wheel (11) and the brake band (10) keeps the balance in the tracing process.Usually, brake makes heat collector be fixed on a certain orientation.When optical detection device (6) when sending deviation signal, through relatively amplifying, make multivibrator produce output signal control tractive magnet (12), it is unclamped, heat collector is rotation westwards under the gravity effect, finishes tracing process.
According to requirement of engineering, solar energy automatic tracking heat collector (3) can a plurality ofly be connected in parallel becomes intergrade in the whole heater, and this intergrade can be a two-stage or more than the two-stage.
Afterbody adopts FAR INFRARED HEATING pot (5), and pitch still can reach the dehydration requirement that heats up when making whole heater working stability and remedying because of the illumination deficiency.
Heaters at different levels are connected in series with metallic conduit (2), and stepped arrangement, so that fluidised form pitch can flow to each grade heat temperature raising in turn under the gravity effect, dewater in terminal at last.
This device adds the technology of heated bitumen to be compared with fuel naked light heating process, and energy savings about 80% has alleviated working strength of workers, has improved the environmental pollution degree, has high economic benefit.
Fig. 1 is a device schematic diagram of the present invention.
Fig. 2 is the schematic diagram of solar energy automatic tracking heat collector of the present invention (3), (4).
Fig. 1 is a kind of successful embodiment.Whole device is by pitch greenhouse (1), the automatic tracking heat collection device of column type (3), (4), far infrared carburetion pot (5) level Four altogether forms through metallic conduit (2) serial connection, the whole device work initial stage, place the fix-bitumen in the greenhouse (1), must initially be fused into fluidised form by other thermal source (as the heating wire heating), so that make the heating works that begin as early as possible at different levels.Greenhouse (1) part daylighting area 95M
2, the parabolic equation of the automatic tracking heat collection device of column type (3), (4) is: Y
2=1600X, daylighting area: each 6M
2, thermal-collecting tube (9) diameter: 90MM, far infrared carburetion pot (5) appearance and size: 1500MM * 1000MM * 1000MM, pitch dehydration power 18KW, insulation power 6KW, 1.2 tons～8 tons of 8 hourly outputs.
Far infrared carburetion pot is an open type, and the good pitch of intensification processed is in far infrared carburetion pot heat preservation for standby use, all the other closed heat temperature raisings that are at different levels.
