Description
Technical Field
[0001] The present invention relates to a greenhouse for cultivating flowers, and more particularly to a temperature and humidity regulation system for a greenhouse for cultivating flowers. Background Art
[0002] Currently, flower cultivation is usually carried out in a greenhouse. Generally, the roof of the greenhouse uses a transparent film to block the cold current from outside and absorb sunlight, thus forming a greenhouse effect inside the greenhouse. However, when there is no sunlight or the sunlight is weak, even if the covering on the roof is thickened, it is still impossible to ensure that the temperature inside the greenhouse is suitable for the growth needs of flowers. This will cause the flowers to be frozen to death under cold climate conditions, making it difficult to continue flower production under cold climate conditions. For this reason, electric wires can be arranged in the greenhouse to generate heat energy by electric heating for the needs of crops. However, arranging electric wires has defects such as a large workload, high energy consumption, inability to be arranged and adjusted arbitrarily, and safety risks. In addition, a dry environment is not suitable for the growth of flowers, and some flowers have relatively high requirements for the dryness and humidity of the environment, which are commonly known as being relatively delicate. In a flower greenhouse, manual operation is usually used to directly spray water on the crops. The work intensity is high, and the water is unevenly received, and the water all falls on the roots and soaks, and the increase in air humidity is not obvious, which is not conducive to the survival and growth of flowers. Using artificial atomization to spray water vapor has an extremely high work intensity, is difficult to industrialize, has low operation efficiency, high crop costs, and high prices.

The air mixing chamber is provided with a homogenization channel that twists and turns to increase the flow and mixing distance of the mist, air, and hot air. The homogenization channel is a spiral pipe or a straight pipe with baffles arranged in a staggered manner on both sides in sequence to make the air flow path serpentine; the spiral pipe is partially or entirely located in the air mixing chamber and is provided with nozzles located outside the air mixing chamber.
[0007] As an improvement to the technical solution of the temperature and humidity regulation system for the flower cultivation greenhouse of the present invention, the output pipe for separating the residual gas is connected to the pipeline between the blower and the air mixing blower and flows in parallel with the input gas.
[0008] As an improvement to the technical solution of the temperature and humidity regulation system for the flower cultivation greenhouse of the present invention, a reforming chamber and a heater arranged around the reforming chamber are provided inside the reformer. The fuel cell is electrically connected to the heater, the liquid pump, the air mixing blower, the blower, and the atomizer respectively.

[0010] As an improvement to the technical solution of the temperature and humidity regulation system for the flower cultivation greenhouse of the present invention, the reformer is electrically connected to an external starting power supply, and the starting power supply is electrically connected to the fuel cell through a charging adapter.
[0011] As an improvement to the technical solution of the temperature and humidity regulation system for the flower cultivation greenhouse of the present invention, the track is a support rail. A raw material tank for containing methanol water and a water tank for containing clean water are fixedly connected in parallel to the chassis of the temperature and humidity regulator. The liquid pump is provided with a suction hose and extends into the raw material tank. Rollers located above the support rail, a traveling motor for driving the chassis and the raw material tank to move are provided at the bottom of the chassis and the raw material tank.

The high-temperature residual gas containing carbon dioxide and water vapor output from the reforming separation, and the low-temperature residual gas output from the fuel cell are input into the gas mixing and air supply device, and then the outside gas is inhaled and adjusted to a suitable temperature, and then output into the greenhouse, thereby increasing the temperature inside the greenhouse; the atomizer generates water vapor to increase the humidity of the greenhouse environment.

Using the atomizer to provide atomized steam and mixing it into the gas mixing and air supply device for sending out together can increase the humidity of the environment inside the greenhouse. Each temperature and humidity regulator is an independent individual and can be arranged at any position according to needs. In areas with a large heat demand, the arrangement density can be larger, so as to provide more heat. Therefore, the adjustment system of this greenhouse can freely scatter and arrange temperature regulators according to needs, thereby saving energy and safely and intelligently adjusting the temperature. The preheating of atomized water and the pre-mixing of the gas to be mixed in the pipe before entering the gas mixing and air supply fan make the mixing more sufficient and tend to be more uniform, and then fully conduct heat exchange, improving the balance of the temperature and humidity of the output air flow.
[0015] Installing the temperature and humidity regulator on the track to slide back and forth can make the heating area in the greenhouse more evenly heated, and the driving motor for the reciprocating sliding action consumes the electric energy generated by the temperature and humidity regulator itself without external power supply.

Detailed implementation manners
[0024] The following further illustrates the detailed implementation manners of the present invention with reference to the drawings.
[0025] As Figures 1 to 3 shown, a temperature and humidity regulation system for a flower cultivation greenhouse of the present invention includes a shed frame located in the flower cultivation greenhouse, and a plurality of temperature and humidity regulators 12 scattered or slidably installed on the shed frame of the greenhouse 11 through a track. The temperature and humidity regulator 12 includes a liquid pump 21 for sucking methanol-water raw materials, a reformer 22 connected to the output port of the liquid pump through a pipeline and used for heating, gasifying and reforming and separating the methanol-water raw materials, a fuel cell 25 for receiving the separated hydrogen through a pipeline, outputting battery exhaust gas and generating electric energy output, a gas mixing air blower 31 for receiving the separated exhaust gas and battery exhaust gas through a pipeline, a fan 33 for injecting external gas into the gas mixing air blower 31 through a pipeline, an atomizer 37 for injecting water vapor into the gas mixing air blower 31 through a pipeline and connected to a water source, a controller 35 electrically connected to the gas mixing air blower 31, the fan 33 and the atomizer 37 respectively, and a temperature and humidity sensor 36 communicatively connected to the controller 35. The output pipe of the separated exhaust gas is provided with a preheating bypass so that at least part of the separated exhaust gas flows through the water tank of the atomizer to preheat water. Refer to Figure 5 、 Figure 6As shown, the high-temperature airflow preheats the water. After the water body is preheated and then atomized, it is more conducive to the temperature uniformity of the fog, overcoming the problems of uneven temperature and humidity of the output airflow. A plurality of temperature and humidity regulators 12 are scattered in the flower cultivation greenhouse, especially in the mushroom crop greenhouse. By reforming and gasifying methanol water and then separating and inputting hydrogen into the fuel cell 25 for power generation for the self-use of the temperature and humidity regulator 12, self-electric heating is realized. The high-temperature residual gas containing carbon dioxide and water vapor output from the reforming separation, and the low-temperature residual gas output from the fuel cell are input into the air mixing and blowing device 31, and then the outside air is inhaled and adjusted to a suitable temperature, and then output into the greenhouse, thereby increasing the temperature inside the greenhouse 11. At the same time, the atomizer 37 uses the electric energy of the fuel cell to pump clear water for atomization to generate water vapor, adjusting the humidity of the greenhouse environment. The randomly attached controller 35 controls the flow rate of the liquid pump 21 and the atomization speed of the atomizer 37 according to the external temperature and humidity data collected by the temperature and humidity sensor 36, thereby controlling the power and heat generation of the reformer 22, realizing stepless speed regulation of the equipment during the process of adjusting the temperature and humidity inside the greenhouse, and keeping the greenhouse 11 at an appropriate temperature and the required humidity environment. At the same time, using the atomizer 37 to directly spray the atomized steam or mix it into the air mixing and blowing device and send it out together can increase the humidity of the environment inside the greenhouse 11.
[0026] Among them, the high-temperature residual gas can be directly sent into the air mixing and blowing device 31, or it can be heat-exchanged with the methanol water raw material in transportation to preheat it, and at the same time, the residual gas is cooled and then sent into the air mixing and blowing device 31. Each temperature and humidity regulator 12 is an independent individual, which can be arranged at any position according to needs. In areas with large heat demand, the arrangement density can be larger, so as to provide more heat. Therefore, the adjustment system of this greenhouse can freely scatter and arrange the temperature and humidity regulators 12 according to needs, thereby saving energy and safely and intelligently adjusting the temperature. Moreover, the gas output for temperature adjustment mainly contains carbon dioxide and water vapor, which is non-toxic and harmless to crops.
[0027] Installing the temperature and humidity regulator 12 on the track 13 to slide back and forth can make the heat reception in the heat-receiving area space of the greenhouse 11 more uniform, and the driving motor 18 for the reciprocating sliding action consumes the electric energy generated by the temperature and humidity regulator 12 itself, without external power supply.
[0028] Preferably, as shown in Figure 4 As shown, a fan 33 is provided between the air mixing and blowing device 31 and the atomizer 37 and is conducted through a duct. The fan 33 has two inlets, which are respectively connected to the atomizer 37 and the outside air. The atomized water vapor generated by the atomizer 37 is sucked into the air mixing and blowing device 31 by the fan 33. At the same time, the other inlet inhales the outside air to mix with the high-temperature gas, and is reduced to a suitable temperature and then transported out, avoiding burning the crops due to the high-temperature output of the hot air, making the temperature adjustment inside the greenhouse 11 softer.
[0029] Preferably, the air-gas mixer has a gas mixing chamber that can be connected to an atomizer and a blower through pipelines. The gas mixing chamber is provided with a homogenization channel that is circuitous and increases the flow and mixing distance of the mist, air, and hot air. The homogenization channel enables sufficient contact between the hot air and the normal-temperature air to generate heat exchange, reducing the temperature difference between them to form a warm air flow with a uniform temperature for output; at the same time, it also equalizes the humidity of the output air flow. The homogenization channel is a spiral tube or a straight-through tube with baffles arranged in a staggered manner on both sides to make the air flow path serpentine. Both methods can extend the air flow path and make the air flow tumble and mix more fully; the spiral tube is partially or entirely located in the gas mixing chamber and is provided with a nozzle outside the gas mixing chamber, so that the gas mixing chamber plays a certain protective role for the spiral tube, and at the same time, the spiral tube located in the gas mixing chamber disturbs the air flow outside the spiral tube.
[0030] Preferably, the output pipe for separating the residual gas is connected to the pipeline between the blower and the air-gas mixer and flows in parallel with the input gas. The two are mixed in a narrow channel, making the mixing more sufficient and more tending to be uniform, and then fully conducting heat exchange.
[0031] Preferably, the reformer 22 is provided with a reforming chamber 23 and a heater 26 arranged around the reforming chamber 23. The fuel cell 25 is electrically connected to the heater 26, the liquid pump 21, the air-gas mixer 31, the blower 33, and the atomizer 37 respectively, realizing self-providing electric energy for machine operation without external power supply. Thus, it can be freely scattered and arranged according to a certain density according to the needs of the area, and can be adjusted at will, and it is very convenient to replace and maintain. The electrical connection is achieved through an electrical conductor for electrical conduction connection.
[0032] Preferably, the air-gas mixer 31 is provided with a heating component 32 electrically connected to the fuel cell 25, which utilizes the excess electric energy for heating and heats the inhaled external natural gas, so that as large a proportion as possible of the electric energy is converted into heat energy, improving the efficiency of heat energy conversion.
[0033] Preferably, the reformer 22 is electrically connected to an external starting power supply 29. The starting power supply 29 is electrically connected to the fuel cell 25 through a charging adapter 28. It stores a certain amount of electric energy usually and can use this power supply to start the reformer 22 when restarting after shutdown, generating separated hydrogen for the fuel cell to use, and then producing electric energy for the reformer to use, realizing its own circular operation.
[0034] Preferably, the track 13 is a supporting rail. The chassis of the temperature and humidity regulator 12 is fixedly connected in parallel with a raw material tank 28 for containing methanol water and a water tank 39 for containing clean water. The clean water is sucked by the atomizer 37 and atomized for output, thereby adjusting the humidity inside the greenhouse 11. The liquid pump 21 is provided with a suction hose 19 and extends into the raw material tank 38 to suck methanol water and supply it to the reformer 22 for reforming and separation, obtaining hydrogen for power generation by the fuel cell 25, and circulating. The chassis and the bottom of the raw material tank 38 are provided with rollers 16 on the upper side of the supporting rail and a traveling motor 18 for driving the chassis and the raw material tank 38 to move. The electricity of the fuel cell 25 is used by the traveling motor 18 to drive the temperature and humidity regulator 12 to reciprocate, so that the temperature and humidity regulation of the regional space can be more balanced, avoiding local long-term heating and local long-term cold, and the humidity increase by atomization is also more uniform. The atomizer 37 is also connected to the water tank 39 through the suction hose 19 to suck clean water.
[0035] Preferably, the track 13 is a suspension rail or a suspension cable. The chassis of the temperature and humidity regulator 12 is hung on the track 13 through a hanger 15 and rollers 16. In addition, a raw material tank 38 for containing methanol water and a water tank 39 for containing clean water are arranged on the ground. The gravity is reduced, thereby reducing the moving resistance of the hanger 15, reducing energy consumption and facilitating the replenishment of raw materials. The liquid pump 21 is connected with a suction hose 19 and the suction port of the suction hose extends into the raw material tank 38. A water pump is provided between the atomizer 37 and the water tank 39 and is connected by a pipeline, and the transportation of raw materials and clean water required for atomization is not hindered during the reciprocating movement.
[0036] Preferably, the hanger 15 is provided with a traveling motor 18 for driving the rollers 16 to rotate, which can more directly drive the hanger 15 to move on the track 13, flexibly and quickly. Driving the rollers 16 to rotate can be more labor-saving and energy-saving. This method can also be used for the supporting rail to drive the temperature and humidity regulator 12 to reciprocate.
[0037] Preferably, referring to Figure 5 As shown, the hanger 15 is fixedly installed with a traveling motor 18. The output shaft of the traveling motor is fixedly provided with two synchronous sprocket wheels 52. The synchronous sprocket wheels 52 are wound around the traction cables in opposite directions. The ends of the traction cables are fixedly connected to the greenhouse frame to make the traction cables taut. The taut traction cables generate a pulling force to drive the motor and the hanger 15 to move, which can be used for the suspension rail and the hanger, and the supporting rail.
[0038] Preferably, the temperature and humidity regulation system for flower cultivation greenhouses further includes a handheld or desktop control console 55. The control console 55 and the controller 35 are respectively provided with signal transmitters to realize mutual signal transmission connection, so that the operation switch and power control of the temperature and humidity regulator 12 can be remotely controlled, and the output power can be adjusted according to the temperature requirement to obtain the corresponding heat output.
[0039] The above-disclosed are only the preferred embodiments of the present invention. Of course, the scope of the rights of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
