Description
Technical Field
The invention relates to a temperature-controlled light source device for a photochemical reaction tank, and in addition, the invention also relates to the photochemical reaction tank with the temperature-controlled light source device.
Background
Photochemical reaction technology is widely used in pharmaceutical, sanitary and chemical engineering fields. The light source is used to irradiate the reactant, so that the reactant can produce chemical reaction under the action of light to produce the product, thereby achieving the required purpose. In addition, ultraviolet light is also commonly used to decompose organic compounds in the fluid to achieve the effect of purifying the fluid.
Most of the current methods for performing photochemical reactions are to place reactants in a container and irradiate the reactants with a light source device to make the reactants generate photochemical reactions. In the prior art, even though different light sources can be selected and changed to obtain proper light-emitting wavelength according to various different reaction requirements, the light-emitting beam cannot penetrate through the reactant without limit, so that the irradiation range of the light source is limited, and even research shows that a common light source can only irradiate to the front two centimeters of radius range and cannot penetrate a little far away, so that the reactant cannot be uniformly irradiated, and the reactant cannot be completely reacted.
On the other hand, most chemical reactions require operation in a high temperature environment, such as above one hundred degrees celsius, and relatively, in order to concentrate the wavelength of the emitted light beam, the current light source device mostly adopts an LED light bar, which can only be in a room temperature environment of tens of degrees celsius during operation, and the light intensity may be reduced by, for example, three percent when the temperature is increased by one degree celsius, and once the light source device bears excessive heat energy, the light emitting efficiency is greatly affected, thereby reducing the efficiency of the photochemical reaction of the reactant. On the contrary, if the light source is fully matched with the requirement of light emitting efficiency, the environment is cooled to a temperature of, for example, two or thirty degrees centigrade which is optimal for light emitting, and the specific temperature range required for the chemical reaction of the reactant is damaged, which is not favorable for the photochemical reaction at the room temperature.
Especially, when the light source can only irradiate to the range of two centimeters of radius on average, the light source which is densely distributed is cooled, and the temperature rising effect in the chemical reaction tank is undoubtedly eliminated. The conventional light source device is not specially designed for chemical reaction, and usually only considers the operating temperature requirement of the light source itself, and provides a cooling device to counteract the heat generation of the light source itself, but does not consider the temperature environment required by the chemical reaction, even the light source needs to be heated rather than cooled because the specific chemical reaction belongs to endothermic reaction.
Furthermore, since the reactant or product sometimes deposits on the outer surface of the light source device, even in organic reaction, it may cause growth of algae or moss, and even microorganisms, and reduce the transmittance of the light source device surface or reactant fluid, the conventional chemical reaction tank is not limited by the above-mentioned reaction efficiency, and thus needs to perform reaction for a long time, and lacks a mechanism for flowing the reactant, or needs to flow the reactant repeatedly for many times, so as to comply with the problem of non-uniform reaction in which only the reactant near the light source device can generate photochemical reaction. The shielding of the light source greatly reduces the efficiency of the photochemical reaction tank for processing the reactant.
Therefore, how to solve the problem that the current light source device cannot be heated and cooled intelligently, and improve the structure of the container for placing the reactant, so as to improve the production efficiency and yield of the reactant, is still a direction in which research and improvement are urgently needed.

The structures, proportions, sizes, and other dimensions shown in the drawings and described in the specification are for illustrative purposes only and are not intended to limit the scope of the present invention, which is defined by the following claims.
In each embodiment of the present invention, the light emitting member may be a light emitting member having a far ultraviolet light source, an infrared light source, a white light source or other predetermined wavelength range, the hollow cylindrical housing in each embodiment is made of a material that is transparent to the main light emitting wavelength of the light emitting member, and the predetermined wavelength range of the light emitting member is determined according to the photochemical reaction to be performed by the reactant.

The temperature control tube 12 is located in the hollow cylindrical housing 11 and is conductively connected to the temperature control device 18, the temperature control device 18 includes a temperature control element 14 and a pump 15, the pump 15 can push the temperature control fluid in the temperature control tube 12 to make the temperature control fluid flow in the temperature control tube 12, when the temperature control fluid flows through the temperature control element 14, the temperature control fluid is cooled or heated by the temperature control element 14 to change the temperature, thereby supplying the temperature control fluid with a specific temperature.
In the present embodiment, the circuit substrate 13 is thermally connected to four surfaces of the temperature control tube 12, and each circuit substrate 13 is provided with a plurality of light emitting members 16, and each light emitting member 16 has a main light emitting wavelength in a predetermined wavelength range, such as a light emitting diode, in the present embodiment, the predetermined wavelength range is determined by the photochemical reaction to be performed. In addition, the hollow cylindrical housing 11 is made of a material that is transparent to light in a predetermined wavelength range, and when the power supply 17 supplies power to the circuit substrate 13, the light emitting member 16 irradiates the reactant in a direction penetrating the hollow cylindrical housing 11. The material of the hollow cylindrical shell 11 also has the characteristics of being corrosion-resistant, heat-resistant, cold-resistant and the like, so as to prevent the hollow cylindrical shell 11 from being damaged due to the corrosion of reactants.
Fig. 3 shows a first preferred embodiment of the photochemical reaction tank with the temperature-controlled light source device according to the present invention, which is described in conjunction with the temperature-controlled light source device 10. The photochemical reaction tank 30 includes a reaction tank main body 31, a temperature-controlled light source device 10 and a partition plate 35, wherein the reaction tank main body 31 forms a reaction space 32, an inlet 33 and an outlet 34, the temperature-controlled light source device 10 longitudinally penetrates through the reaction tank main body 31 and is accommodated in the reaction space 32, the partition plate 35 forms a through hole 36 for the hollow cylindrical shell 11 to penetrate through, and is transversely arranged in the reaction space 32 in an up-down staggered manner, so that the reaction space 32 is partitioned to form a flow channel for connecting the inlet 33 and the outlet 34 in a conduction manner. The reactant may continuously flow in through the inlet 33, and after a chemical reaction is generated by illumination, the reactant may flow out through the outlet 34, or the outlet 34 and the inlet 33 may be connected so that the reactant repeatedly circulates in the reaction space 32 until the concentration of the product reaches a desired target.
In this embodiment, after the reactant flows in from the inlet 33, it flows from the left side of the uppermost first layer to the right side, and then flows downward from the right side to the second layer, while the reactant in the second layer flows from the right side to the left side, and then flows downward from the left side to the third layer, and then flows to the outlet 34 in the above manner. The flow path of the reactant inside the photochemical reaction tank 30 is shown by the dotted line in fig. 3, and the inside of the reaction space 32 is partitioned by the partition plate 35, so that the flow path of the reactant is longer, the time for the reactant to be irradiated can be increased, and the reactant can be uniformly irradiated by the temperature-controlled light source device 10.
Of course, although the inlet 33 is disposed above the main body 31, if the inlet is disposed below the main body 31, the reactant can be flowed to the outlet by a motor or a pump.
The light emitting element 16 generates heat energy when it is illuminated, and in this embodiment, the operation temperature of the reaction chamber itself is higher than the operation temperature range of the light emitting element. If the heat energy accumulated in the light emitting member 16 is too much, the life of the light emitting member is shortened and the efficiency of light emission is reduced after an operation limit temperature is exceeded. Therefore, in order to avoid the light emitting element 16 accumulating excessive heat energy, the temperature control device 18 cools down the temperature of the temperature control fluid flowing through the temperature control element 14, and the cooled temperature control fluid can absorb the heat energy emitted by the light emitting element 16 when flowing through the position relative to the circuit substrate 13, thereby reducing the temperature of the light emitting element 16 and avoiding exceeding the operation limit temperature.
However, in order to avoid the temperature control device 18 cooling the luminescent member 16 too much, which would reduce the temperature in the photochemical reaction tank too much, the temperature control fluid is controlled to be near the above-mentioned operation limit temperature, such as within 5 degrees celsius or above 80 degrees celsius, so as to keep the luminescent intensity of the luminescent member 16 and the chemical reaction proceeding smoothly. Thereby, it is ensured that the luminescent member 16 can be kept at, for example, 80 degrees celsius, and even if the temperature of the reactant in the immediate vicinity of the temperature-controlled light source device 10 is slightly lowered to hundreds of degrees celsius, the reactant slightly away from the temperature-controlled light source device 10 can still be kept at the desired chemical reaction temperature. Moreover, as can be easily understood by those skilled in the art, the hollow cylindrical housing 11 itself can be added with an auxiliary temperature control component, even without considering the price factor, a double-layer glass housing is selected, and the middle part is vacuumized and insulated, so as to ensure that the operating temperature of the light emitting element is within the operation limit temperature range, and maintain the internal and external partial temperature difference, so as to minimize the temperature influence on the reaction tank.
The second preferred embodiment of the photochemical reaction tank with the temperature-controlled light source device of the present invention is shown in fig. 4 and 5, and since most of the components are similar to those of the first preferred embodiment, the description of the same parts in this embodiment is omitted, and only the differences will be provided.
The photochemical reaction tank 40 further includes a feedback sensing device 41 and a cleaning device, in this embodiment, the cleaning device is a driver 42 disposed on both sides of the reaction tank main body 47. The feedback sensing device 41 includes a light sensor 43 and a processor 44, the light sensor 43 is used for sensing the light emitted by the light emitting element and transmitted out of the hollow cylindrical shell, converting the light into an electrical signal according to the received light intensity and outputting the electrical signal to the processor 44, after the processor 44 receives the electrical signal, it will determine whether to move the driver 42 according to the light intensity, if the light intensity is weaker, it indicates that too much dirt is accumulated on the outer surface of the hollow cylindrical shell, the light is blocked and cannot be completely radiated outwards, and the driver 42 controls the partition plate 45 to move up and down along the rail 48, so that the dirt such as reactant, product or algae, which is left or accumulated on the outer surface of the hollow cylindrical shell of each temperature control light source device 46 and the inner surface of the reaction tank main body 47.
The driver 42 can also be used to adjust or control the distance between the partitions 45, in this embodiment, six partitions 45 are provided, wherein two partitions 45 have been moved by the driver 42 to the upper and lower parts inside the reaction tank main body 47, respectively, when the reactant needs more irradiation time, the driver 42 can move the partitions 45 above and below downwards and upwards, respectively, and adjust the distance between the remaining partitions 45, so that the flow path of the reactant can be longer, and the irradiation time can be increased.
As shown in fig. 6, a second preferred embodiment of the temperature-controlled light source device 60 in this embodiment includes a hollow cylindrical housing 61, a temperature-controlled fluid (not shown), and a circuit substrate 62. Unlike the previous embodiment, the six-sided circuit boards 62 are disposed on the side surfaces of the column 64, and the temperature control fluid in this embodiment is an insulating and non-conductive liquid, and can directly flow in the hollow cylindrical housing 61 without affecting the operation of the circuit boards 62. Therefore, the heat generated by the light emitting element 63 disposed on the circuit substrate 62 can be quickly and directly conducted to the temperature control fluid for heat dissipation. In another aspect, the temperature control fluid can also be used to raise the temperature of the reactant, and in order to make the light emitting member 63 have better light emitting efficiency, the temperature control fluid is controlled at a control temperature which is not higher than the operation limit temperature of the light emitting member 63 and is close to the proper reaction temperature required by the reactant. In addition, the cleaning device of the photochemical reaction tank can also be the cleaning brush 65 in the embodiment, the cleaning brush 65 is disposed outside the temperature-controlled light source device 60, and by controlling the cleaning brush 65 to move up and down, the outer surface of the hollow cylindrical shell 61 is cleaned, so as to avoid the influence of the accumulated excessive reactant or product on the irradiation of the light.
In a third preferred embodiment of the photochemical reaction tank with a temperature-controlled light source device of the present invention, as shown in fig. 7 and 8, the photochemical reaction tank 70 includes a reaction tank main body 71, a spiral partition 72, and a temperature-controlled light source device 73, wherein the temperature-controlled light source device 73 includes a hollow cylindrical housing 74, a plurality of circuit substrates 75 and a temperature-controlled fluid (not shown), and each circuit substrate 75 is provided with a plurality of light-emitting members 76. A reaction space 77 is formed between the reaction tank main body 71 and the hollow cylindrical shell 74, and a spiral partition 72 is provided inside the reaction space 77, so that the reactant, after entering the reaction space 77, flows spirally toward the other end of the reaction tank main body 71 with the hollow cylindrical shell 74 as an axis. Through the spiral partition 72 structure in this embodiment, the flow path of the reactant can be increased, so that the time for the reactant to be irradiated with light can be increased, and the reactant can be uniformly irradiated with the light emitting member 76.
In this embodiment, the temperature control fluid is also an insulating and non-conductive liquid, and the temperature control fluid can directly flow in the hollow cylindrical housing 74 to take away the heat generated by the light emitting element 76 on the circuit substrate 75 or reversely provide the heat to the light emitting element 76 for heat preservation. In this embodiment, when the reactant is performing an endothermic photochemical reaction, and it is necessary to absorb heat energy to perform the photochemical reaction, the temperature control fluid is heated, so that the temperature control fluid can heat the luminescent member 76 and the reactant when flowing through the position corresponding to the reaction space 77, on one hand, the temperature of the luminescent member 76 is prevented from being lowered below an operation limit temperature of, for example, 20 degrees celsius or less, and on the other hand, the reactant can be irradiated by the luminescent member 16 at the appropriate reaction temperature.
