Specific embodiment
Present embodiment provides a kind of embodiment, with the present invention is further described.
In one embodiment, as the heat recovery system, thermal power plant based on seawater as cooling water of Dalian use in winter
System, including closed irrigation canals and ditches, with tilt flat plate type upper cover 1, the outer surface of the upper cover 1 is laid with insulating layer, on described
The inclined direction of lid 1 opens up several condensed water drainage channels on it, which, which converges in, is placed in the upper cover
Hermatic door is installed at the guiding gutter 2 on 1 inclination bottom edge, the both ends of the closed irrigation canals and ditches, and the guiding gutter 2 is stretched out by hermatic door.
In heat transfer process, a large amount of vapor are had in upper cover 1 and are condensed into condensed water, are typically considered a kind of recyclable clean water,
To be recycled to this part water, plate inclination upper cover 1 is set by upper cover 1, and opens up several condensed water drainage canals
Road drains the condensed water for condensing in upper cover 1 by gravity, and converges in the guiding gutter 2 on the inclination bottom edge of upper cover 1, with
So that this partial coagulation water is collected.And it is laid with insulating layer, it is to guarantee that low temperature season does not freeze, when such as winter, upper cover 1 is warm
Spend it is low, may cause condensation water freezing the problem of appearance.The tilt angle of the tilt flat plate type upper cover is 5~10 degree, excellent
8 degree are selected as, since the purpose that upper cover is obliquely installed is to collect condensed water, if tilt angle is too small, condensed water is not easy
Flowing, cannot reach guiding gutter, so that condensed water can not be collected by drainage；And wide-angle is crossed, and condensation water flow velocity is difficult to
Control generates overflow phenomena, and excessive angle, also wastes a large amount of heat preservation layer material, which is by a large amount of
Angle replacement experiment discovery preferred range, condensed water flow velocity under the range is ideal, gathering speed can be adapted to, and
Overflow phenomena will not occur, under the angle, the use for keeping the temperature layer material not will lead to apparent increased costs.In the embodiment
In, the evaporation and condensation water of seawater is recycled, is to obtain a kind of very effective means of clean water, this recycling occurs
In heat transfer process, the water of recycling is further promoted, for example, the flow of processed seawater is 10000 ton/hours, according to
The evaporation capacity of a ten thousandth, evaporation capacity hourly can achieve 1 ton, and the clean water energy collected reaches 24 tons or so within one day, receives
The water of collection is considerable.
In the system, the water inlet of the seawater flowed into after exchanging heat for the first time is mounted on the hermatic door of side, and has filtering
Net, to filter out the thing of the more big parts such as the rubbish that falls into during discharge flow of seawater after exchanging heat for the first time.It is described
The horizontal lower cover of irrigation canals and ditches is laid with a ZuUXing PE intermediary water return pipe 3, is in Semi surrounding type between each PE intermediary water return pipe 3 of the group
Uniformly arrangement, and closely knit in gap filling sand, each PE intermediary water return pipe 3 is equipped with circulating pump, and with intermediary's water water tank
Connection, and control valve is installed on connecting pipe；The intermediary's water circulated in U-shaped PE intermediary water return pipe 3, water tank
Intermediary's water in the water supplement PE intermediary water return pipe 3 in water tank can be used directly from tap water, when needed in water.
Exchange heat as the seawater of cooling water and the turbine condenser of thermal power plant, seawater after heat exchange by side hermatic door into
Enter, exchange heat in the closed irrigation canals and ditches with intermediary's water in PE intermediary water return pipe 3, and the heat is passed through into heat pump unit progress
Next round heat exchange, to supply the workshop or house of irrigation canals and ditches two sides, in this way, even if user disperses, however, since discharge seawater is along row
It puts channel and is in flow regime, each dispersion user can be supplied thermal energy to achieve the purpose that obtain heat nearby, and use sand
On the one hand closely knit U-shaped PE intermediary water return pipe 3 plays fixing pipe, on the other hand, the heat transmitting of sand preferably, is suitble to change
Heat uses, if not using sand, once the impurity Long-Term Sorption being easily bonded on pipe, will extreme influence heat exchange effect
Rate.
Seawater after exchanging heat for the first time is entered by side hermatic door, in the closed irrigation canals and ditches with PE intermediary water return pipe 3
In intermediary's water heat exchange；One layer of water-permeable brick 4 is covered on the upper layer of PE intermediary water return pipe 3, the inclination of water-permeable brick 4 is laid with, and
The row's of digging out ditch near the water-permeable brick 4 for being located at inclination lowest part is connected to the water-permeable brick 4 for being located at inclination lowest part with row's ditch,
For row's ditch equipped with scraper plate, Pai Gouzhong is equipped with the track advanced for scraper plate；The upper cover 1 and the laying of water-permeable brick 4 are inclined
Tilted direction is consistent；Purpose using water-permeable brick 4 is to form one layer of filtering between U-shaped PE intermediary water return pipe 3 and water inlet, make
Water can be exchanged heat and impurity is filtered by water-permeable brick 4 by water-permeable brick 4, and in order to avoid water-permeable brick 4 is bonded by impurity, inclined
Tiltedly setting as long as ditch is arranged in periodic cleaning, and makes so that impurity slides down into Pai Gou by gravity, by water-permeable brick 4
It driving scraper plate most to arrange ditch with track to be cleared up, period and the intensity of controller control cleaning can be used, cleaning effect is preferable,
Extend water-permeable brick 4 uses time and clearance time.The laying tilt angle of the water-permeable brick is 7~12 degree, preferably 10
Degree preferably can attach permeable slip layer in water-permeable brick upper surface in this scenario, so that impurity, which is easier to slide, falls into Pai Gou,
The purpose that water-permeable brick inclination is laid with is in order to enable impurity is slid down onto row's ditch by gravity, since seawater is when introducing power plant,
It is primary by filtering, thus, the seawater of impurity significantly relatively in the sea is few in discharge process, in this case, be not necessarily to so that
Water-permeable brick tilt angle is excessive；Water-permeable brick tilt angle is big, and impurity is easy to fall, however but but also seawater be easy row ditch it is attached
Nearly accumulation, leads to the non-uniform problem that exchanges heat, and angle too small, impurity are not easy to fall into Pai Gou, find by a large amount of inclined experimentals,
Above range is ideal, and within this range, impurity is easy to be slipped to Pai Gouzhong, and the not seawater product near the row's of will cause ditch
It is poly-, and upper cover 1 is consistent with the laying inclined direction of water-permeable brick 4, in order to when overflow occurs for the condensed water of upper cover, due to
The condensing water temperature and ocean temperature difference fallen will affect heat exchange uniformly, thus, above-mentioned restriction is made, even if overflow occurs,
Since inclined direction is consistent, overflow water can generally far from water-permeable brick, reduce the influence of heat exchanging near the row's of flowing to ditch.In this reality
It applies in example, the amount that preferably seawater introduces closed irrigation canals and ditches, which maintains, just not to be had water-permeable brick or do not had water-permeable brick, and did not had second just
Driving chain, heat transfer effect is preferable at this time.
It is filtered, is found in multiple practice, water-permeable brick 4 makes however, it has been found in practice that only using water-permeable brick 4
It is still undesirable with the time, in order to increase the use time of water-permeable brick 4, also for filter effect is improved, increase heat exchange efficiency, saturating
The upper layer of water brick 4 is laid with corrosion-resistant net 5, and the corrosion-resistant net 5 is single layer of wires net, it is of course also possible to be multilayer steel wire, net
Silk is uniformly arranged in transverse and longitudinal square crossing；Drive roll 6 and driven voller 7 are mounted on the support frame of left and right sides hermatic door, and first

The rear end of the drive roll 6 is connected with the rear end of the driven voller 7, so that the drive roll 6 and the driven voller 7 link, institute
Corrosion-resistant net 5 is stated to be covered on the first driving chain 8 or the second driving chain 12；With this, so that the circulation of corrosion-resistant net 5 is driven,
Impurity is allowed to be bonded on steel wire, and in order to increase the filter effect of steel wire and using the time, in the both sides sealing door
One or two of support frame is equipped with outer net perching knife, to root out the outer impurity being bonded on the net, the perching knife can cooperate with
Bracket stretches out, and can strike off outer net sticky object, under there is splicing groove, catch adhesive, with periodic cleaning, thus, the biography
