The slower technical problem of technology heating.
The content of the invention
The purpose of the present invention is there is above mentioned problem for existing technology, it is proposed that a kind of series-connected solar thermal-arrest system
System, series-connected solar system pipeline length shorten reduce hot water pipeline flowing in heat loss, improve collecting efficiency.
The purpose of the present invention can be realized by following technical proposal：A kind of series-connected solar collecting system, it include into
Water pipe, outlet pipe, attemperater and some groups of heat collectors, the heat collector include the header and some thermal-arrests of a tubulose
Pipe, one end of thermal-collecting tube is inserted into header, is connected between header by the connecting tube for making all heat collectors be cascaded, the
One header is connected with attemperater by water inlet pipe, and the header of last position is connected by outlet pipe with attemperater, is incubated water
Have on case and filling pipe is connected with the flow pipe that hot water is outwardly provided, water inlet pipe, water inlet pipe is provided with circulating pump.
Cold water enters heat collector by water inlet pipe, and the heat that thermal-collecting tube absorbs sunshine transfers heat to header, header
Between connected by connecting tube, sequentially enter next header, enter attemperater after final fully heat absorption, attemperater is by sending
Water pipe outwardly conveys hot water, and attemperater water level supplements cold water when too low by filling pipe.
Further, filling pipe be provided with water compensating valve, for water level it is low when amount of makeup water.
Further, thermal-collecting tube improves collecting efficiency with ground in 25 degree of angles.
Further, the system is provided with 20 groups of heat collectors, and every ten groups are that a row are arranged side by side.
Further, water inlet pipe is provided with check-valves one, prevents water from flowing back.
Further, flow pipe is provided with check-valves two, prevents water from flowing back.
Further, level sensor is provided with attemperater, attemperater water level is detected, water is supplemented when too low.
Compared with prior art, advantages of the present invention has：
1. thermal-collecting tube has about 25 degree of angle with ground, its heat transfer is similar to vertical setting of types pipe, the physics of heat transfer
Curve is shortened, and heat conduction velocity is also just accelerated.
2. collecting system of connecting, its pipeline connecting length is attemperater to twice of nearest heat collector distance, and
Its duct length will not typically increase with the increase of heat collector, save cost.
3. temperature difference circulation under the same conditions, the time used in series connection collecting system, are four points of common string and system
One of, so the service life of circulating pump will extend, the maintenance of circulating pump, renewal cost are substantially reduced.
4. not needing blast pipe and air bleeding valve within 60 groups of collecting system of connecting, cost is saved.
5. header is the design of shape, greatly enhance system bearing capacity, system service life is greatly prolonged.
6. header designs for " centering type+tilting ", once system breaks down, and it is general in thermal-collecting tube to occur that water shortage shows
As so the possibility of bombing is preferably minimized significantly.
7. the installation for collecting system of connecting is adapted to the roofing of various structures, not any limitation in heat collector direction realizes 360 degree
Chaoyang.
8. collecting system supporting structure of connecting is simple, steel are saved.
