The invention relates to the technical field of solar greenhouses, in particular to a solar
greenhouse piping system with ventilation and carbon dioxide supply functions.
As a unique greenhouse structure in China, solar greenhouse is an important facility for
vegetable supply, widely used in northern China. In the actual production of solar
greenhouse, in order to increase the yield, it is necessary to apply more carbon dioxide.
For the needs of dehumidification and cooling, ventilation is also necessary. At present,
the ventilation of solar greenhouse is basically to set a ventilation window on the roof or
back wall so as to cool and dehumidify by introducing outdoor cold air, but the outdoor
temperature is extremely low in winter, especially in Northeast China, even as low as
-30°C. If opening window at this time, the extremely cold air will instantly reach the plant
growth area, causing irreversible chilling or freezing injury to plants, which seriously
affects plant production.
When necessary, the solar greenhouse needs to add carbon dioxide. At present, it often
adopts pipe laying to add carbon dioxide, which requires extra pipelines expenses,
occupies the limited indoor cultivation space of the solar greenhouse and reduces the
space utilization efficiency.
The purpose of the invention is to provide a solar greenhouse piping system which can
not only ventilate the solar greenhouse conveniently, but also provide carbon dioxide for
the solar greenhouse.
The main improvement of the piping system is that the supporting keel of the solar
greenhouse is hollow, and the supporting keel is provided with a plurality of ventholes
communicated with the hollow parts. And the supporting keel is connected with an air
supply device or a carbon dioxide supply device through pipelines.
The keel is a hollow structure with ventholes, which can play the role of a pipeline,
thereby replacing the piping system for supplying carbon dioxide. Therefore, the
invention can directly supply carbon dioxide to the greenhouse through the keel and
realize ventilation by blowing air.
Preferably, these supporting keels are connected in series with each other through
pipelines. With multiple keels are connected in series through pipes, the air can be
transferred to other keels to realize the overall air supply, as long as one keel is connected
with the air supply device or carbon dioxide device.
Preferably, the keels are connected in parallel with each other through pipelines. The
specific mode of parallel connection is that all keels are mutually connected with a main
air pipe at first, and the main air pipe is connected with the air supply device and/or the
carbon dioxide supply device, so that the main air pipe can supply air to all supporting
keels at the same time. By setting the main air pipe, the main air pipe can supply air to all
keels at the same time, which can reduce the loss of air in the transmission process, thereby efficiently utilizing the air provided by the air supply device or the carbon dioxide supply device and saving energy.
Preferably, the ventholes are distributed on the side of the supporting keel opposite to the
crop cultivation area. The venthole is arranged on the side opposite to the crop cultivation
area, so that the air provided by the air supply device or the carbon dioxide supply device
can directly act on crops, which is beneficial to realize the direct action on the crops.
Preferably, the ratio of the diameter of the venthole to the diameter of the hollow keel is
1: 6-15. The diameter of the venthole is related to the required air quantity, the number of
vents and other factors, and the diameter of the venthole can be changed within the above
range when other factors meet the production requirements.
Preferably, the air supply device comprises an intelligent controller, a preheater and an air
blower. The intelligent controller is respectively connected with the preheater and the air
blower. Besides, the air blower, the preheater and the supporting keels are connected in
turn. The intelligent controller can automatically collect the temperature and humidity of
indoor and outdoor air and control the opening or closing of the preheater and air blower
according to the different indoor and outdoor temperatures. If the outdoor air temperature
is too low, the air will be sucked into the preheater by the air blower, heated by the
preheater, and then blown into the greenhouse keels by the air blower. The air will be
released into the greenhouse through these small ventholes, thus cooling and
dehumidifying the greenhouse. If the outdoor temperature can meet the indoor
temperature demand, it will not be heated after being sucked into the preheater by the air
blower but will be blown into the keels again by the air blower to supply air to the
greenhouse.
Preferably, the carbon dioxide supply device comprises an intelligent controller and a
carbon dioxide storage tank which are connected with each other, and the carbon dioxide
storage tank is connected with a supporting keel. The intelligent controller automatically
monitors the concentration of indoor and outdoor carbon dioxide. In the daytime
photosynthesis stage, when the greenhouse carbon dioxide is lower than the set value, it
automatically starts to supply carbon dioxide to the keels with the help of the carbon
dioxide storage tank. The carbon dioxide air flows in the keels and is released to the plant
canopy area through the small holes in the pipeline.
Preferably, the carbon dioxide supply device further comprises a booster pump which is
connected with the intelligent controller. The addition rate of carbon dioxide can be
adjusted by adjusting the pressure.
The intelligent controller used in this application can be obtained through market
purchase and people can also write its own control program according to requirements to
realize relevant control functions. The air blower, preheater and carbon dioxide storage
tank involved in this application can be obtained through market purchase as well.
Preferably, the air supply device and the carbon dioxide supply device share an intelligent
controller, so that one intelligent controller can control two supply systems at the same
time, thereby saving costs.
Preferably, one or more sets of air supply devices or carbon dioxide supply devices are
provided, wherein the number of them can be adjusted according to the size of the
greenhouse or the air demand.
As the most preferred scheme, the piping system of the invention comprises hollow
supporting keels, air supply devices and carbon dioxide supply devices.
The hollow supporting keel is provided with a plurality of ventholes passing through the
hollow parts. Besides, the ventholes are distributed on the side of the support keel
opposite to the crop cultivation area. These supporting keels are connected in series or in
parallel with each other through pipelines.
The air supply device comprises an intelligent controller, a preheater and an air blower.
Wherein, the intelligent controller is respectively connected with the preheater and the air
blower. The air blower is connected with the preheater and the preheater is connected
with supporting keel through pipelines.
The carbon dioxide supply device comprises a carbon dioxide storage tank and a booster
pump, which are both connected with an intelligent controller.
As the preferred implementation mode of the most preferred scheme, the specific
operation mode of the parallel connection is that all supporting keels are connected with a
main air pipe at first, and then the main air pipe is connected with the air supply device or
the carbon dioxide supply device, thereby, the main air pipe can supply air to supporting
keels at the same time.
A second object of the present invention is to introduce carbon dioxide into the solar
greenhouse by utilizing the piping system described in the application, comprising the
following steps.
1) When the level of carbon dioxide in outdoor air is higher than that in indoor air, the
outdoor cold air is supplied into the solar greenhouse through the air supply device and
released into the greenhouse through the keels, so that the carbon dioxide level in the
greenhouse is adjusted to the same level as that of outdoor air.
2) Turning on the carbon dioxide supply device and adjusting the carbon dioxide content
to the required level.
Through the above operation, we can make full use of the carbon dioxide in the
environment, avoid the additional use of carbon dioxide, and reduce the production cost,
especially when the carbon dioxide content is high in the northern winter environment.
The invention aims to protect a solar greenhouse provided with the piping system of the
application.
The piping system provided by the invention has the following beneficial effects.
1) According to the invention, the keel is designed to be hollow and provided with
ventholes, which can replace the carbon dioxide supply system. Therefore, it can not only
provide carbon dioxide or air for the greenhouse, but also play a supporting role of the
keel itself, thereby realizing the multifunction of the keel.
2) According to the invention, the air is heated through the adjustment of the
intelligent controller, so that the temperature of the air input into the greenhouse is
controllable, and the damage to crops caused by low temperature can be avoided.
3) The piping system of the invention has simple structure and low cost and is
beneficial to wide popularization and use.
