The terms used in this specification in the description of the present utility model are only for the purpose of describing specific embodiments and are not used to limit the present utility model. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0017] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0018] Figure 1 and Figure 2 is a photocatalytic system for chemical liquids provided by an embodiment of the present utility model. As Figure 1 and Figure 2 shown, the photocatalytic system mainly includes: a liquid storage device that stores chemical liquids; a sunlight photocatalytic chamber 10; a simulated photocatalytic chamber 20 and a control equipment room 30

[0019] Among them, at least a part of the sunlight photocatalytic chamber 10 is made of a transparent material, allowing sunlight to pass through and enter the sunlight photocatalytic chamber. A first manifold 11 is fixedly received inside the sunlight photocatalytic chamber 10.

[0020] The first manifold 11 has a first input end 12 and a second input end 13, and is connected to the liquid storage device (for example, a storage tank) through a pipeline, so that the chemical liquid in the liquid storage device can flow into the first manifold 11 and be catalyzed and activated under the action of sunlight.

[0021] Specifically, the sunlight photocatalytic chamber 10 can be composed of a frame and transparent glass, providing sufficient light transmission capacity to allow sunlight to penetrate and enter the interior of the catalytic chamber. Inside the sunlight photocatalytic chamber, a first support 14 for carrying the first manifold box 11 is also provided.

[0022] Among them, the first support 14 can have adjustable horizontal feet. The first manifold box 11 is installed and fixed on the first support 14. Supported by the first support 14, it is spaced from the bottom of the sunlight photocatalytic chamber by a preset distance.

[0023] Specifically, the first manifold box 14 can be a box structure in the shape of a cuboid. It is enclosed by a single layer of high borosilicate glass, which can reduce the loss of light intensity and improve the light efficiency.

[0024] In addition, the first input end 12 and the first output end 13 are arranged along the diagonal of the cuboid first manifold box 14. For example, it is input from the upper left corner and output from the lower right corner. The diagonal arrangement can improve the medium circulation in the manifold box and effectively improve the light uniformity.

[0025] Preferably, the sunlight photocatalytic chamber 10 is also provided with one or more devices such as a fan, a spraying device, and an irradiation sensor to help enrich its functions and improve the photocatalytic efficiency and the convenience of use.

[0026] Among them, the fan can be used to form convective air in the sunlight photocatalytic chamber to prevent overheating in summer. The spraying device can be arranged at a position adjacent to the first manifold box and periodically clean the dust on the outer surface of the first manifold box by spraying. The irradiation sensor can be arranged on the top surface of the sunlight photocatalytic chamber to collect sunlight irradiation sampling data and provide it to the corresponding control device to achieve automatic control of the photocatalytic process.

[0027] The simulated photocatalytic chamber 20 is the part that completes photocatalysis using a simulated light source. Multiple simulated light sources 40 can be arranged inside it as a supplement to sunlight. A second manifold box 21 is also housed and fixed inside the simulated photocatalytic chamber 20.

[0028] Similarly, the second manifold box 21 also has a second input end 22 and a second output end 23, and is also connected to the above liquid storage device through a pipeline. The chemical liquid in the liquid storage device can also be controlled to flow into the second manifold box 21 and be catalyzed and activated under the action of the simulated light source.

[0029] Specifically, the second manifold box 21 is also in the shape of a cuboid and is enclosed by a double layer of high borosilicate glass. The design of the double layer of glass can prevent the influence of external faults on the second manifold box 21 while ensuring sufficient light intensity.

[0030] More specifically, the simulated light source 40 can be set in three groups. One group of the simulated light sources 40 is hoisted above the top of the simulated photocatalytic chamber and irradiates the second manifold 21 from the top surface. The other two groups of simulated light sources 40 are respectively arranged on the opposite sides of the second manifold 21 in the width direction and irradiate the second manifold 21 from the two side surfaces respectively.

[0031] Preferably, in order to ensure the normal and reliable operation of the system equipment, a temperature sensor is arranged on each simulated light source to collect the lamp temperature of the simulated light source, and an appropriate number of temperature sensors can also be arranged in the control equipment room to collect the temperature information of the control equipment room and the control device.

[0032] A series of control devices 31 are arranged and accommodated inside the control equipment room 30. It can be used to control the operation of the simulated light source and the state of the chemical liquid in the first manifold 11 and the second manifold 21.

[0033] Specifically, the above-mentioned control equipment room 30 can be arranged closely to the simulated photocatalytic chamber 20. A part of the partition wall can be shared between the two, and they are separated by a specifically arranged isolation door.

[0034] Among them, the air pressure inside the control equipment room 30 is greater than the air pressure outside the control equipment room. Air enters the inside of the control equipment room 30 from the outside through the filtration and humidification equipment, thereby forming a positive-pressure control equipment room to improve the safety of the equipment.

[0035] Such a positive-pressure control equipment room can maintain a relatively constant temperature and humidity inside the control equipment room, and at the same time provide a working environment for the control device and relevant operators that is not polluted by external dust and peculiar smell. Preferably, an observation window can also be arranged on the isolation door to facilitate the viewing of the equipment and prevent damage to the human body by light.

[0036] Based on the photocatalytic equipment provided by the embodiment of the present invention, the control device can also execute Figure 3 the photocatalytic method shown in the manner to complete the photocatalytic process of the chemical liquid. As Figure 3 shown, the method includes:

[0037] S100. Determine whether the current time belongs to the first scenario or the second scenario according to one or more sampling data.

[0038] Among them, the first scenario is the time when the natural sunlight intensity is greater than the preset value; the second scenario is the time when the natural sunlight intensity is less than the preset value.

[0039] S200. In the first scenario, control the chemical liquid in the liquid storage device to enter the first manifold, and complete the photocatalytic process of the chemical liquid by sunlight.

[0040] S310. When in the second scenario, control the chemical liquid in the liquid storage device to enter the second manifold box.

[0041] S320. When the chemical liquid enters the second manifold box, control the simulation light source to operate in a suitable manner to provide the required simulated sunlight and complete the photocatalytic process of the chemical liquid.

[0042] Preferably, when the photocatalytic irradiation intensity of the chemical liquid cannot be satisfied by the first manifold box, the chemical liquid can also be controlled to enter the second manifold box, and the simulated sunlight provided by the simulation light source supplements the appropriate irradiation intensity.

[0043] The following takes the photocatalytic operation of the butanediol raw material as a specific example to describe in detail the specific implementation manner of the present invention.

[0044] In the subsequent use of the butanediol raw material, chemical reagents need to be added to achieve a corresponding change in the chromaticity value. In the actual use process, a green, environmentally friendly and energy-saving method can be adopted, using sunlight irradiation to realize the photocatalytic reaction, replacing the role of adding chemical reagents, so as to achieve the goals of improving quality, increasing value and efficiency.

[0045] Among them, natural sunlight is used for irradiation on sunny days, and when the solar irradiance is insufficient on cloudy days or at night, it is supplemented by a simulation light source. The combination of the two photocatalytic chambers realizes the purpose of planned production and increasing production and efficiency.

[0046] The above photocatalytic reaction is realized through the following photocatalytic system:

[0047] 1) Liquid storage device:

[0048] The butanediol raw material is stored in the storage tank in the finished product tank area. A solar photocatalytic chamber, a simulation photocatalytic chamber and a control equipment room are arranged at a position close to the finished product tank area. A flow pump can be arranged at the bottom of the storage tank, and connections are established with the first manifold box and the second manifold box in the solar photocatalytic chamber and the simulation photocatalytic chamber respectively through pipelines. The butanediol can be pumped into the solar photocatalytic chamber or the simulation photocatalytic chamber by controlling the flow pump for intelligent production.

[0049] The specific parameters of the storage tank and the circulation pump are as follows: Tank body size: diameter 3200*8500MM (T / T); Tank body volume: 175M3; Pressure: 0.3MPA, operating pressure: atmospheric pressure; Pump type: centrifugal pump; Rated flow: 50M3 / H; Head: 48M; Motor power 15KW; Circulation pump diameter: inlet diameter DN100, outlet diameter DN80; Flow: 50M3 / H.

[0050] 2) Solar photocatalytic chamber:

[0051] On the premise of ensuring the light intensity and the temperature of the appropriate medium properties, the size of the solar photocatalytic chamber should be minimized as much as possible. Its main body adopts a frame-type assembled structure. High-transmittance borosilicate glass is set on the top and embedded in the roof structure members, and the surrounding is an open or semi-closed glass structure.

[0052] Such a structural design can not only prevent water and dust, but also evacuate and cool the room temperature when the temperature is too high in summer, and provide heat preservation for the medium when the temperature is too low in winter.

[0053] The size of the solar photocatalytic chamber can be: 4m * 3m * 2.5m (length * width * height); and the size of the first busbar box can be: 2m * 2m * 1m (length * width * height). The first busbar box is fixed on the first bracket, and the height from the ground is 0.5m.

[0054] 3) Simulated photocatalytic chamber and control equipment room:

[0055] Since the finished product tank area is an explosion-proof area, in order to provide sufficient explosion-proof performance, the equipment room divided into a simulated photocatalytic chamber and a control equipment room can adopt the air circulation form of a positive pressure machine room. A positive pressure machine room means that the air pressure inside the equipment room is greater than that outside the equipment room, and air enters the equipment room from the outside through filtration and humidification equipment, thus ensuring the air quality inside the equipment room.

[0056] The main body of the equipment room adopts a frame-type assembled structure, and rock wool heat insulation plates are assembled and built inside the frame. Two areas, front and back, are set inside the equipment room. The rear area forms a simulated photocatalytic chamber, and the front area forms a control equipment room. The size of the equipment room is: 6.5m * 5.5m * 4m - (length * width * height); the size of the second busbar box is: 2m * 1m * 2m - (length * width * height). The second busbar box is fixed on the second bracket, and the height from the ground is 0.5m.

[0057] Among them, the simulated light source can be divided into three groups for setting. One group of simulated light sources can be set on the upper part of the second busbar box, and the downward lighting method is adopted to output the solar irradiance intensity downward to the medium in the second busbar box.

[0058] One group of simulated light sources is set on each side of the second busbar box. The simulated light source can adopt a two-layer installation structure, and the light distribution area is set by computer simulation, so that the light output by the simulated light source evenly irradiates the side area of the second busbar box, and the light from the two sides can converge to meet the irradiance of the medium.

[0059] For example, within 5 - 8 minutes of sunlight irradiation time, the flow rate of the medium in the busbar box is about 4.17 m³. At this time, calculating 4.17 * 12 = 50.04 m³ / H can meet the production needs, and the light intensity is 1000W / m 2 .

[0060] In the control equipment room formed in the front area, there is an operation area for setting one or more control devices such as a power supply box and an electrical control cabinet. The way of setting the concentrated area of the electrical part can provide protection and appropriate explosion-proof performance.

[0061] An isolation door for heat insulation and radiation isolation is set between the front area and the rear area. To ensure a good temperature environment, an air supply outlet can be set at the bottom of the equipment room, and an exhaust system is set at the top, so that the temperature in the equipment room is constant within the range of 30 - 45 °C. Of course, the simulation photocatalytic chamber and the control equipment room have the function of temperature zoning.

[0062] 4) Simulation light source:

[0063] A set of three groups of simulators for generating simulated sunlight is hoisted at the top. The specific parameters of the simulator are: equipment power: 3 - 5KW * 3 * 1; input voltage: 380V; frequency: 50HZ. The position of the equipment hoisted at the top is: 0.5 - 1 meter (height difference from the second busbar box).

[0064] One set of four groups of simulators for simulating sunlight is installed vertically on both sides. The specific parameters of the simulator are: equipment power: 3 - 5KW * 4 * 2; input voltage: 380V; frequency: 50HZ. The position of the equipment installed vertically is: 0.5 - 1 meter (horizontal distance from the second busbar box).

[0065] Specifically, the relevant equipment configuration of the above simulation light source is: 3 sets of equipment structures; 11 sets of light source box modules; 11 sets of optical modules; 11 trigger modules; 3 sets of electrical cabinets; 11 sets of power supply modules; 1 set of main control cabinet; 1 set of equipment constant temperature system; 1 set of sensor module and 11 sets of light source cooling systems.

[0066] The specific parameters of each group of simulation light sources are as follows: irradiation area: 2m * 2m * 1m cuboid spliced light spot (effective area of the busbar box); spectral matching degree: AM1.5G; radiation spatial uniformity: < ±10%; time instability: < ±2%; radiation intensity: 700 - 1300 W / m 2 ; 2KW - 5KW xenon light source; component temperature control adopts air-cooled method, temperature range 0 - 50 ± 10 °C; thermocouple temperature measurement range 0 - 200 °C, test accuracy ±0.5 °C; irradiance meter measurement range: 0~1800W / m 2 ; switching power supply: 1KW electronic switching power supply combination, output greater than 60V; light source power is adjustable, output range 60 - 100%.

[0067] 5) Control equipment for the simulation light source:

[0068] The electric control cabinet of the control equipment room has the following specific parameters: Power supply type: electronic power supply (EPS control); Power supply characteristics: electronic square wave current power supply, no stroboscopic; Software control: control electric cabinet with an independent industrial control touch screen and microcomputer touch screen interface control; Modulation function: radiation intensity adjustment, parameter display, lamp tube status, over-temperature display; Modulation range: The power of the lamp group and single lamp can be automatically adjusted by software within the range of 60 - 100%.

[0069] During modulation, a radiation intensity of 1000 W / m2 can be initially set for the lamp tube for testing purposes. The initial power point of EPS is usually set at about 80%, so that the lamp tube has a significant upward modulation compensation ability after light intensity attenuation.

[0070] For example, after 1000 hours, the average light intensity of the lamp group attenuates to 900 W / m2, and it can be automatically modulated to a power point of about 90% through the EPS software, and the radiation intensity returns to 1000 W / m2 again.

[0071] 6) Power supply box for power supply:

[0072] In the control equipment room, a set of power supply boxes and control cabinets are arranged on both sides respectively. The specific parameters of the two sets of power supply boxes are as follows: Electric control cabinet power: 3 - 5 KW * 3 * 1 set; 3 - 5 KW * 4 * 2 sets; Input voltage: 380 V; Frequency: 50 HZ; Output voltage: 30 - 42 V / group; Output current: 85 - 130 A / group.

[0073] 7) Electrical system:

[0074] The control cabinet uses a cabinet with a protection level of IP54; the cable inlet of the cabinet uses a protection level above IP54. There is an electrical socket strip inside the cabinet. The protection level is IP20 inside the electrical cabinet and IP65 on site.

[0075] The panel switches of the control cabinet include: main power switch and related buttons, emergency stop button, total stop button, local / remote button, operation start button and other main operation and safety control buttons are independently set and represented by different colors.

[0076] The power wiring adopts international standards: that is, the black wire is the AC380V power supply wire, the blue wire is the DC24V power supply wire, the orange wire is the non - cuttable AC220V power supply wire, and the yellow / green wire is the grounding protection wire.

[0077] Each control cabinet is equipped with a standard three - hole power socket with a capacity of: AC220V, 15A. An operation / maintenance manual placement box is set inside the control cabinet, and at the same time, component number plates corresponding to the drawings are pasted near the electrical components.

[0078] The wire / cable sheath has line number plates or sleeves corresponding to the drawings. The line numbers are machine-printed to ensure clarity and non-fading, and to ensure good grounding of the system and protection of the wires / cables.

[0079] 8) Irradiance sensor:

[0080] Five sets of irradiance sensors can be equipped, with one set installed in the solar photocatalysis chamber, three sets installed on the top of the equipment room, and one set installed inside the equipment room. The main technical parameters of the irradiance sensor are as follows: Sensitivity: 7 - 14 μV / 1w / m-2; Response time: ≤30 seconds (99%); Stability: ±3%; Non-linearity: ±3%; Test range: 0 - 1800W / m 2 .

[0081] The irradiance sensor is a sensor based on the photoelectric principle. Its sensing element uses a high-precision photosensitive element, which has characteristics such as wide-spectrum absorption, high absorption in the full spectral range, and good stability. The irradiance sensor can output an electrical signal proportional to the solar irradiance within the linear range.

[0082] Preferably, a temperature compensation circuit can also be configured to reduce the influence of temperature. In addition, in order to prevent the environment from affecting its performance, two layers of quartz glass covers with a light transmittance of 95% or more, which are ground by optical cold processing and have good photosensitivity, can be added. The surface of the two-layer quartz glass cover is specially treated to prevent dust adsorption and has good thermal stability.

[0083] Through the above-set irradiance sensor, it can quickly respond to changes in irradiance, accurately output signals to the corresponding control devices, and achieve intelligent control.

[0084] 9) Temperature sensor:

[0085] Fourteen sets of temperature sensors can be set. Among the 11 sets of lamps of the simulated light source, one temperature sensor is set for each set, and 4 sets are set in the equipment room. The technical parameters of the temperature sensor are as follows: Sensor temperature range: -50 to 200 °C; Accuracy: ±0.1 °C.

[0086] Specifically, the lamps of the simulated light source use movable armored platinum resistors for acquisition to obtain the surrounding temperature. The equipment room uses fixed platinum resistors for acquisition, and its characteristics of excellent linearity, sensitivity, fast heat transfer, stability, and uniformity can well meet the performance requirements.

[0087] 10) Communication protocol:

[0088] In addition to the equipment room, an additional main control room can be set up. The main control room and the equipment room are connected by optical fiber transmission, providing a DSL communication protocol, and a 485 communication interface is also reserved in the PLC. The main control room provides rich control functions, including: switch equipment buttons; equipment conversion settings; equipment operation settings; irradiance parameter settings; temperature control settings; remote start; smoke alarm settings and reserved monitoring interfaces, etc.

[0093] The above is only the implementation mode of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
