[0020] Example 1 As Figures 1-12As shown, the present application provides a glass steel composite washing tower with intelligent monitoring device, which comprises a tower body 10, a grid plate 106 is arranged below the inner wall of the tower body 10, an inlet 101 and a filler placing port 102 are arranged above the grid plate 106 on the outer wall of the tower body 10, a tower top 103 is arranged at the top end of the tower body 10, a liquid level meter 104 and a liquid discharge port 105 are arranged at the bottom of the outer wall of the tower body 10, the liquid discharge port 105 is located at the bottom end of the outer wall of the tower body 10, a valve is arranged in the liquid discharge port 105, and a smoke outlet pipe 30 is arranged at the top end of the tower top 103; a sampling pipe 70 is arranged inside the tower body 10 above the grid plate 106, at least one third liquid guide pipe 703 is arranged on the side wall of the sampling pipe 70, a sample liquid temporary storage box 80 is arranged at the end of the third liquid guide pipe 703 away from the sampling pipe 70, the sample liquid temporary storage box 80 is arranged on the outer wall of the tower body 10, an electric conductivity analyzer 801 is arranged at the end of the sample liquid temporary storage box 80 away from the tower body 10, a detection pipe 802 is arranged at the top of the electric conductivity analyzer 801, an electric conductivity sensor is arranged at the end of the detection pipe 802 away from the electric conductivity analyzer 801, and the electric conductivity sensor is arranged inside the sample liquid temporary storage box 80; a spraying pipe fitting 202 is arranged inside the tower body 10 above the sampling pipe 70, a first liquid guide pipe 201 is arranged on the side wall of the spraying pipe fitting 202, a circulating pump 20 is arranged at the end of the first liquid guide pipe 201 away from the spraying pipe fitting 202, and the circulating pump 20 is arranged at the bottom end of the tower body 10; a demister mounting seat 40 is arranged inside the tower body 10 above the spraying pipe fitting 202, a wire mesh demister 401 is arranged in the demister mounting seat 40, a support block 402 is arranged at the bottom of the demister mounting seat 40, and the support block 402 is used for supporting the wire mesh demister 401; at least two demister fixing assemblies 50 are arranged at the top end of the demister mounting seat 40, a pressing plate 60 is arranged at the top end of the demister fixing assembly 50, and the pressing plate 60 is used for limiting the demister fixing assembly 50 and the wire mesh demister 401; at least one mounting plate 90 is arranged on the inner wall of the tower body 10, a plurality of temperature sensors 902 are arranged on the mounting plate 90, and a temperature display 903 is arranged on the outer wall of the tower body 10.

[0021] The glass fiber reinforced plastic composite washing tower with an intelligent monitoring device of the application has the support block 402 located at the bottom inside the defoamer mounting seat 40, which provides stable support for the wire mesh defoamer 401 and ensures that the wire mesh defoamer 401 will not be displaced during the working process. The defoamer fixing assembly 50 further strengthens the fixing effect of the wire mesh defoamer 401, and the pressing plate 60 further limits the defoamer fixing assembly 50 and the wire mesh defoamer 401 to prevent them from loosening or shaking under the airflow impact of the wire mesh defoamer 401, so as to ensure that the wire mesh defoamer 401 can work stably and prevent the position of the wire mesh defoamer 401 from deviating during use, which in turn causes the effect of removing the foam and liquid drops in the flue gas after washing to decrease. When the flue gas with foam and liquid drops passes through the wire mesh defoamer 401, the foam and liquid drops will be attached to the wire mesh, so as to realize gas-liquid separation and improve the cleanliness of the discharged flue gas. At the same time, the structure design is also convenient for disassembling and maintaining the wire mesh defoamer 401 later. When the wire mesh defoamer 401 needs to be cleaned or replaced, the wire mesh defoamer 401 can be easily taken out through the cooperation of the pressing plate 60 and the defoamer fixing assembly 50, which reduces the maintenance cost and time. When the washing work is carried out inside the tower body 10, the washing liquid will flow into the sample liquid temporary storage box 80 through the sampling pipe 70. The conductivity sensor can detect the conductivity of the washing liquid in the sample liquid temporary storage box 80 and transmit the data to the conductivity analyzer 801. With the progress of the washing process, the pollutant concentration in the washing liquid will gradually increase, and the conductivity will also change accordingly. Through the monitoring of the conductivity, the staff can accurately master the pollution degree of the washing liquid. When the conductivity reaches a certain threshold value, it means that the washing effect of the washing liquid may decrease. At this time, the valve of the liquid discharge port 105 can be opened in time to discharge the seriously polluted circulating liquid, and the circulating liquid is arranged to be replaced, so as to ensure the continuous and efficient operation of the washing tower and avoid affecting the washing effect due to excessive pollution of the washing liquid.The plurality of temperature sensors 902 mounted on the mounting plate 90 of the inner wall of the tower body 10 cooperate with the temperature display 903 of the outer wall of the tower body. The temperature sensors 902 can sense the temperature at different positions in the tower in real time and transmit the temperature data to the temperature display 903. During the washing process, the temperature change in the tower will affect the washing effect. If the temperature is too high, the solubility of some pollutants may change, or the rate of chemical reaction may be affected. Through the temperature display 903, the staff can observe the temperature in the tower in real time and adjust the washing process parameters in a timely manner, such as adjusting the flow and temperature of the circulating liquid, to ensure that the washing process is carried out under the best temperature conditions, improve the washing efficiency and quality. In addition, the plurality of temperature sensors 902 can monitor the temperature at multiple positions in the tower. The staff can comprehensively judge the situation in the tower through the temperature at different points, and then make more accurate judgments. The liquid level meter 104 is mounted at the bottom of the outer wall of the tower body 10. The liquid level meter 104 can display the liquid level of the washing liquid in the tower body 10 in real time. The staff can intuitively understand the inventory of the washing liquid by observing the liquid level meter 104. When the liquid level is too low, the washing liquid can be added in time to avoid affecting the normal progress of the washing work due to insufficient washing liquid. When the liquid level is too high, the washing liquid can be properly discharged through the liquid discharge port 105 to prevent the washing liquid from overflowing the tower body 10 and causing resource waste and environmental pollution. The liquid level is maintained within a reasonable range during the washing process. The grid plate 106 is arranged below the inner wall of the tower body and is used to support the filler layer. The flue gas entering the tower body 10 can be fully contacted with the washing liquid sprayed by the spray pipe 202, which improves the gas-liquid contact area and mass transfer efficiency, and thus enhances the washing effect. It is worth noting that the above-mentioned circulating pump 20, liquid level meter 104, wire mesh demister 401, conductivity analyzer 801, temperature sensor 902 and temperature display 903 can adopt mature models suitable for the field. In addition, the connection circuit thereof is well known to those skilled in the art, and the specific model and connection circuit of the above-mentioned structure are not described in detail.

[0022] Further, in another embodiment, the demister fixing assembly 50 includes a connecting plate 501, a fixed pressing plate 502 and a movable shaft 5023. The connecting plate 501 is fixed to the top end outer wall of the demister mounting seat 40. The fixed pressing plate 502 is mounted in the connecting plate 501. The fixed pressing plate 502 is rotatably connected to the connecting plate 501 through the movable shaft 5023.

[0023] The fixed pressing plate 502 can be flexibly rotated around the movable shaft 5023. When the wire mesh demister 401 needs to be installed, the fixed pressing plate 502 is rotated to tightly fit the edge of the wire mesh demister 401, and then the fixed pressing plate 502 is fixed with the connecting plate 501 through fasteners, so as to stably install the wire mesh demister 401 on the demister mounting seat 40. When disassembling, the fasteners are loosened and the fixed pressing plate 502 is rotated, so that the wire mesh demister 401 can be conveniently removed from the demister mounting seat 40. The structure design not only ensures the stability of the installation of the wire mesh demister 401, but also greatly simplifies the installation and disassembly process of the wire mesh demister 401, facilitates the regular cleaning, maintenance and replacement of the wire mesh demister 401 by the staff, ensures that the wire mesh demister 401 always maintains good demisting effect, and avoids affecting the normal operation of the washing tower due to clogging or damage of the wire mesh demister 401.

[0024] Further, in another embodiment, limit holes 5024 are formed on both sides of the fixed pressing plate 502 close to one end of the connecting plate 501, a limit rod 503 is assembled in the limit hole 5024, a limit rod connecting block 504 is fixed to the outer wall of the limit rod 503 away from the limit hole 5024, a stop block 505 is fixed to the outer wall of the connecting plate 501 away from the fixed pressing plate 502, and the limit rod connecting block 504 is located between the stop block 505 and the connecting plate 501. The limit rod connecting block 504 and the stop block 505 are connected by a plurality of limit springs 506.

[0025] When the staff needs to rotate the fixed pressing plate 502, the limit rod 503 can be pulled away from the fixed pressing plate 502, at which time the limit spring 506 is in a compressed state. Then the fixed pressing plate 502 can be rotated around the movable shaft 5023 until it is tightly fitted with the edge of the wire mesh demister 401. When the fixed pressing plate 502 is tightly fitted with the edge of the wire mesh demister 401, the staff can loosen the limit rod 503, and the limit spring 506 can gradually return to its original state, thereby pushing the limit rod 503 towards the fixed pressing plate 502 until the limit rod 503 is clamped in the limit hole 5024, thereby limiting the fixed pressing plate 502 horizontally, further enhancing the tightness of the fixed pressing plate 502 and the edge of the wire mesh demister 401, avoiding the fixed pressing plate 502 from deviating due to vibration during the operation of the washing tower, and thus improving the overall stability of the wire mesh demister 401 after installation. When the wire mesh demister 401 needs to be disassembled, the limit rod 503 can be pulled out of the limit hole 5024, and the fixed pressing plate 502 can be rotated to complete the disassembly operation of the wire mesh demister 401. The quick fixing and disassembly structure realized by the cooperation of the limit rod 503, the limit hole 5024 and the limit spring 506 greatly simplifies the operation process and reduces the operation difficulty of the staff, making the maintenance work of the wire mesh demister 401 more convenient and efficient, effectively saving maintenance time and labor cost.

[0026] Further, in another embodiment, the pressing plate 60 is provided with at least two pressing blocks 601, and the number of pressing blocks 601 corresponds to the number of demister fixing assemblies 50. The outer wall of the pressing plate 60 is provided with at least two fixing seats 602. The two sides of the fixing pressing plate 502 are provided with pressing grooves 5022. The two sides of the bottom end of the pressing block 601 are provided with clamping blocks 6011. The middle part of the bottom end of the pressing block 601 is provided with a positioning rod 6012. The middle part of the fixing pressing plate 502 is provided with a positioning hole 5021 for accommodating the positioning rod 6012.

[0027] A threaded hole is formed through the fixing seat 602. The pressing plate 60 is fixed on the demister mounting seat 40 through the fixing seat 602 and a bolt. At this time, the pressing plate 60 is attached to the upper surface of the wire mesh demister 401. The pressing block 601 can abut against the top of the demister fixing assembly 50. When the pressing plate 60 is fixed on the demister mounting seat 40 through the bolt on the fixing seat 602, the clamping blocks 6011 on the two sides of the pressing block 601 can be embedded in the pressing grooves 5022 on the two sides of the fixing pressing plate 502, thereby limiting the fixing pressing plate 502 in the vertical direction to prevent displacement. At the same time, the positioning rod 6012 in the middle part of the bottom end of the pressing block 601 is inserted into the positioning hole 5021 in the middle part of the fixing pressing plate 502, thereby further ensuring the accuracy of the alignment of the pressing block 601 and the fixing pressing plate 502. The pressing plate 60 and the demister fixing assembly 50 can form a full-covering limiting and fixing on the top edge of the wire mesh demister 401, thereby further ensuring the working stability and demisting efficiency of the wire mesh demister 401.

[0028] Further, in another embodiment, the top wall of the sampling pipe 70 is provided with at least one set of second liquid guide pipes 701. Each set of second liquid guide pipes 701 is provided with a plurality of second liquid guide pipes 701. The top end of each set of second liquid guide pipes 701 is provided with a sampling seat 702. The inside of the sampling seat 702 is provided with sampling holes 7021 corresponding to the number of second liquid guide pipes 701 in each set.

[0029] During the gas washing process of the washing tower, a certain amount of washing liquid flows from the sampling holes 7021 in the inside of the sampling seat 702 into the second liquid guide pipes 701, and then flows into the sampling pipe 70 through the second liquid guide pipes 701. In addition, the second liquid guide pipes 701 can be arranged in multiple groups at different positions of the sampling pipe 70 according to actual needs. Correspondingly, the sampling seat 702 is also provided with multiple sampling seats 702 according to the number and position of the second liquid guide pipes 701. The arrangement of multiple sampling seats 702 at different positions can realize larger range sampling operation. To some extent, the large range sampling can improve the accuracy of sampling, so that the obtained sample is more representative, thereby providing more reliable data support for subsequent related operations or analysis.

[0030] Further, in another embodiment, the sampling tube 70 is peripherally sleeved with at least one sampling tube sleeve ring 704, and the sampling tube sleeve ring 704 is fixed to the inner wall of the tower body 10.

[0031] The sampling tube sleeve ring 704 can stabilize the installation position of the sampling tube 70 inside the tower body 10, avoiding displacement or shaking of the sampling tube 70 due to vibration or air flow impact during operation of the washing tower. Meanwhile, the fixed connection mode of the sampling tube sleeve ring 704 and the inner wall of the tower body 10 can be selected from welding, bolt connection or buckle connection according to actual installation requirements, to ensure the reliability and stability of the connection. In addition, if the length of the sampling tube 70 is relatively long, multiple sampling tube sleeve rings 704 can be peripherally arranged at intervals, to further enhance the support effect of the sampling tube 70 through the joint action of multiple sleeve rings, preventing the sampling tube 70 from being bent and deformed due to its own gravity or external forces, and ensuring that the sampling tube 70 can stably perform sampling work for a long time.

[0032] Further, in another embodiment, the sample liquid temporary storage tank 80 is provided with a liquid level window 803 near one end of the conductivity analyzer 801, and the sample liquid temporary storage tank 80 is provided with a fourth liquid guide pipe 804 at the bottom end. The fourth liquid guide pipe 804 is provided with a guide pipe 8041 at the end away from the conductivity analyzer 801, and the guide pipe 8041 is connected to the inside of the tower body 10 away from the fourth liquid guide pipe 804. The guide pipe 8041 is provided with a valve inside.

[0033] The operator can directly observe the real-time liquid level height of the sample liquid in the sample liquid temporary storage tank 80 through the liquid level window 803, so as to timely understand the storage condition of the sample liquid and perform corresponding processing. The fourth liquid guide pipe 804 is arranged to guide the sample liquid in the sample liquid temporary storage tank 80 out, and the guide pipe 8041 is connected to the inside of the tower body 10, so that the sample liquid can be returned to the inside of the tower body 10 when needed, realizing the recycling or reprocessing of the sample liquid. The valve inside the guide pipe 8041 controls the flow and cut-off of the sample liquid. When it is needed to discharge the liquid in the sample liquid temporary storage tank 80 or perform a return operation, the valve can be opened. When the sample liquid temporary storage tank 80 is in a sampling and analysis state or needs to keep the internal sample liquid stable, the valve can be closed to ensure the normal work of the sample liquid temporary storage tank 80.

[0034] Further, in another embodiment, the mounting plate 90 is provided with a plurality of mounting holes 901, and the temperature sensor 902 is provided with mounting clamping columns 9021 on both sides near one end of the mounting plate 90. The temperature sensor 902 is assembled on the mounting plate 90 through the mounting clamping columns 9021.

[0035] The threaded hole is arranged on the mounting column 9021, and an operator can use common connecting pieces such as bolts to cooperate with the mounting hole 901, so as to complete installation and fixation of the temperature sensor 902. In addition, the mounting plate 90 is designed with a plurality of mounting holes 901, which are reasonably distributed and sufficient in quantity, so that a worker can select different positions to install the temperature sensor 902 according to actual work requirements, so as to ensure that the temperature sensor 902 can be arranged at different key points inside the tower body 10, thereby realizing monitoring of multiple points of temperature inside the tower body 10, which not only improves the coverage range of temperature detection, but also further guarantees the accuracy and reliability of the temperature detection result.

[0036] Further, in another embodiment, a plurality of first guide plates 301 are arranged at one end of the flue gas outlet pipe 30 close to the tower top 103, and a plurality of second guide plates 302 are arranged at the other end of the flue gas outlet pipe 30 away from the tower top 103.

[0037] The flue gas outlet pipe 30 is designed as an elbow, so that when the flue gas flows in the flue gas outlet pipe 30, the residence time of the flue gas in the flue gas outlet pipe can be effectively prolonged through the turning at the elbow and the guiding action of the first guide plates 301 and the second guide plates 302. At the same time, the first guide plates 301 and the second guide plates 302 can also have a certain buffering and dispersing effect on the flue gas, so as to avoid the direct and rapid discharge of the flue gas, so that the part of liquid carried therein has more opportunities to contact the inner wall of the flue gas outlet pipe 30 or the first guide plates 301 and the second guide plates 302, thereby reducing the occurrence of liquid discharge with flue gas and improving the purification efficiency of the scrubbing tower.

[0038] Working principle: when the glass fiber reinforced plastic composite scrubbing tower with an intelligent monitoring device is running, the flue gas to be treated is introduced into the tower body 10 through the flue gas inlet 10. At this time, the circulating pump 20 is started to deliver the scrubbing liquid at the bottom of the tower body 10 to the spray pipe 202 through the first liquid guide pipe 201. The scrubbing liquid is uniformly sprayed on the filler layer through the spray head on the spray pipe 202 to form a liquid film. The flue gas contacts the liquid film on the surface of the filler layer during the rising process, and the pollutants in the flue gas are absorbed or chemically reacted by the scrubbing liquid to achieve preliminary purification. The preliminarily purified flue gas continues to rise and then enters the wire mesh demister 401. The wire mesh demister 401 can effectively remove the liquid droplets carried in the flue gas to avoid resource waste and secondary pollution caused by the discharge of the liquid droplets with the flue gas. The purified flue gas passes through the flue gas outlet pipe 30, and under the guidance of the first guide plates 301 and the second guide plates 302, the residence time is prolonged, and the liquid droplets are further separated, and finally discharged from the flue gas outlet pipe 30. In this process, the conductivity analyzer 801 monitors the conductivity of the circulating liquid in real time, the temperature sensor 902 monitors the temperature at different positions in the tower, the liquid level meter 104 displays the washing liquid level, and the staff adjusts the process parameters in a timely manner according to these monitoring data to ensure the efficient and stable operation of the washing tower. At the same time, the defoamer fixing assembly 50 and the pressing plate 60 work together to ensure the stable installation of the wire mesh defoamer 401, the sampling pipe 70 and the sample liquid temporary storage box 80 provide convenience for the composition analysis of the washing liquid, and the sampling pipe sleeve ring 704 ensures the stability of the sampling pipe 70. The temperature sensor 902 on the mounting plate 90 realizes multi-point temperature monitoring through reasonable arrangement.
