Amount size) control heating rate and hot blast temperature；By humidity discharging air force control room humidity size), it is achieved to hothouse 1
The control of internal humiture.
Wherein voltage stabilizing air port 27 configures a unidirectional air-valve, when using residual heat from kiln furnace heating mode, in order to keep hothouse 1
Internal gas pressure is constant, is got rid of by the additional air in hothouse 1 and can effectively prevent outdoor air from entering indoor simultaneously；Circulating fan 28
Use frequency conversion fan with moisture-eliminating blower 32, can at any time blower fan rotational frequency be adjusted, it is achieved automatically control；New wind air intake
Outdoor new wind is filled in hothouse 1 by pipe 23, the air of loss when working in order to supplementary moisture-eliminating blower 32, it is ensured that hothouse 1
Internal gas pressure is stable.
When only with combustion type heating mode: residual heat from kiln furnace ratio air-valve 25 (the ratio air-valve at the first blast pipe
25) and voltage stabilizing air port 27 ratio air-valve 25 is in normally off, on the circulated air blast pipe 22 in hothouse 1 (i.e. second enters
On airduct) ratio air-valve 25 is in normally open, and circulating fan 28 is in full frequency duty.When hothouse 1 starts to warm up,
When the full frequency of circulating fan 28 rotates, in air stove 20, form negative pressure, air in hothouse 1 is led to circulated air blast pipe 22 through the
Two air inlets 201 enter in air stove 20, and burner 24 is lighted, and heat the air of process, and hot blast is by circulating fan 28
Import indoor hot air pipeline 10, (quantity of air outlet 11 is multiple, it is simple to hot blast by air outlet 11 through hot-blast pipe line 10
Quickly discharge) it is delivered to indoor, it is achieved indoor intensification；When indoor temperature is incremented by, base substrate temperature raises, and base substrate interior humidity is waved
Sending in hothouse 1 space, indoor humidity raises, the now humidity discharging ratio air-valve 33 on humidity discharging airduct 31 and fresh inlet 203
The proportioning valve at place is opened, and moisture-eliminating blower 32 is opened and run, according to moisture fluctuation value and fluctuation speed size, moisture-eliminating blower 32 frequency conversion
Device adjusts frequency automatically, controls rotation speed of fan and proportioning valve openings of sizes.
When only with residual heat from kiln furnace formula heating mode: at (on the second blast pipe) the ratio air-valve 25 on circulation airduct
Ratio at normally off, residual heat from kiln furnace ratio air-valve 25 (the ratio air-valve 25 on the i.e. first blast pipe) and voltage stabilizing air port 27
Air-valve 25 is in automatic control state.When hothouse 1 starts to warm up, circulating fan 28 rotates, and forms negative pressure, by kiln in air stove 20
In hot blast inspiration air stove 20 in waste heat pipe, waste heat hot blast is imported indoor hot air pipeline by air stove 20 by circulating fan 28
10, it is being delivered to indoor through hot-blast pipe line 10 air outlet 11, it is achieved indoor intensification.In temperature-rise period, visited by indoor temperature
Head and set temperature value, according to thermometric instrument ratiometric conversion, system (controls automatically by controlling circulating fan 28 converter numerical value
Circulating fan 28 air quantity) and residual heat from kiln furnace ratio air-valve 25 aperture (controlling hot blast air quantity), thus control circulated air air outlet 11
Hot blast air quantity, prevents indoor overheating problem.System is according to residual heat from kiln furnace ratio air-valve 25 aperture size, coordinated signals voltage stabilizing
Air port 27 ratio air-valve 25 aperture size, makes indoor residual heat from kiln furnace intake equal to voltage stabilizing air port 27 exhaust air rate, it is ensured that at Shi Nei
In pressure constant state.When indoor temperature is incremented by, base substrate temperature raises, and base substrate interior humidity evaporates in hothouse 1 space, indoor
Humidity raises, and now humidity discharging airduct 31 proportioning valve is opened, and moisture-eliminating blower 32 is opened and run, according to moisture fluctuation value and fluctuation speed
Size, moisture-eliminating blower 32 converter adjusts frequency automatically, controls rotation speed of fan and proportioning valve openings of sizes.
When using hybrid heating mode: system is run early stage and used residual heat from kiln furnace intensification operation principle to heat up,
When residual heat from kiln furnace cannot meet indoor temperature demand, temperature elevation system 2 is automatically heated up by residual heat from kiln furnace and is converted to combustion type intensification
Mode.Along with humidity discharging (i.e. arranging outside indoor humidity) in temperature-rise period, indoor are in negative pressure, now residual heat from kiln furnace ratio air-valve 25
And/or the ratio air-valve 25 at new wind airduct is according to humidity discharging opening amount size, automatically adjusts valve area, it is ensured that indoor constant voltage.Cause
The new wind covered during humidity discharging is the hot blast of kiln preheating, therefore can cancel or reduce air stove 20 and again add hot blast
Heat, effectively saves fuel cost and puts into.And newly wind blast pipe 23 designs near burner 24, it is to first pass through burning that new wind fills into
Device 24 heats, and then in importing hothouse 1, can avoid because the new wind imported exists temperature difference with air in hothouse 1, impact
Body drying quality.
This kind of heating mode, early stage first uses residual heat from kiln furnace heating mode principle to run, when indoor temperature and humidity probe detection
To heating rate reduce or temperature value cannot meet hothouse 1 demand time, burner 24 automatic ignition in air stove 20, to kiln
Stove waste heat wind is heated again, improves the temperature of residual heat from kiln furnace wind, it is achieved indoor heating rate and the lifting of temperature value.
Described above illustrate and describes the preferred embodiments of the present invention, as previously mentioned, it should be understood that the present invention not office
Be limited to form disclosed herein, be not to be taken as the eliminating to other embodiments, and can be used for other combinations various, amendment and
Environment, and can be changed by above-mentioned teaching or the technology of association area or knowledge in invention contemplated scope described herein
Dynamic.And the change that those skilled in the art are carried out and change are without departing from the spirit and scope of the present invention, the most all should be appended by the present invention
In scope of the claims.
