Description

Technical Field

[0001] This invention relates to the relevant technical field, and in particular to a hydrolysis oxidation device for the treatment of organic waste gas. Background Technology

[0002] With the rapid development of industrial manufacturing, the amount of organic waste gas emissions has been increasing year by year. Such waste gas has a complex composition and is highly toxic. If it is directly emitted, it will cause serious pollution to the atmospheric environment and also harm human health. Therefore, the treatment of organic waste gas has become one of the core tasks in the field of environmental protection. At present, the adsorption-desorption-catalytic oxidation process is widely used in the treatment of organic waste gas due to its high treatment efficiency and wide applicability.

[0003] The existing activated carbon placement racks are mostly fixed structures. When replacing activated carbon, the only options are to remove the entire rack or remove the carbon one by one. Removing the entire rack generates a lot of dust, which not only pollutes the operating environment but may also endanger the health of the operators. Removing the carbon one by one is inconvenient for workers to remove the carbon from racks that are located high up, making the operation difficult and inefficient. Summary of the Invention

[0004] The technical problem to be solved by the present invention is the problem raised in the background art, specifically a hydrolysis oxidation device for the treatment of organic waste gas.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows: a hydrolysis oxidation device for treating organic waste gas, comprising an air inlet pipe, a plurality of filter boxes connected by first adsorption valves at equal intervals on the top surface of the air inlet pipe, two door hinges symmetrically on one end of each filter box, a first desorption pipe connected to the lower side of each filter box, a desorption fan connected to one end of the first desorption pipe via a connecting pipe, the output end of the desorption fan connected to the upper side of a catalytic box via a pipe, a plurality of heat exchange plates at equal intervals on the upper side of the inner wall of the catalytic box, a catalytic block in the middle of the inner wall of the catalytic box, a plurality of heating rods arranged in a serpentine pattern at equal intervals on the lower side of the inner wall of the catalytic box, a second desorption pipe connected to the top surface of the catalytic box, a plurality of second desorption valves at equal intervals on one side of the second desorption pipe, the plurality of second desorption valves being connected to the upper side of the plurality of filter boxes respectively, and an air outlet pipe connected to the top surface of each of the plurality of filter boxes via the second adsorption valves;

[0006] The filter box is also equipped with intelligent control components, including an analysis module;

[0007] The analysis module uses a VOCs concentration sensor to detect the VOCs concentration at the inlet and outlet of the filter box in real time. By plotting the curve of the adsorption rate of new activated carbon over time and analyzing the slope change, it determines whether the activated carbon has reached adsorption saturation. At the same time, it records and preprocesses the cumulative adsorption time data to determine its fluctuation range. Based on historical data, the activated carbon is marked as saturated and unsaturated. The current data of unsaturated activated carbon is compared with historical data to calculate the remaining time to reach adsorption saturation. If the time is less than a preset threshold, it is determined that the activated carbon needs to be replaced, and a replacement count is started. Correction coefficients for multiple factors such as temperature, humidity, exhaust gas flow rate, activated carbon particle size, and airflow distribution are introduced. Combined with the actual adsorption efficiency, the true saturation affected by interference is calculated. When the true saturation exceeds the preset threshold, it is determined that the activated carbon needs to be replaced, and a replacement count is started. Then, after the replacement count reaches the threshold, a replacement signal is generated and wirelessly transmitted to remind the staff to replace it in time.

[0008] Preferably, the determination steps for the initial replacement of the analysis module are as follows:

[0009] M1: Calculate the adsorption efficiency based on the VOCs concentration at the inlet and outlet of the filter box; obtain the adsorption rate data during the use of new activated carbon, and plot the data coordinates of each time point in the time-adsorption rate coordinate system and connect them sequentially to calculate the slope of each continuous line segment; when the slope of the connecting line approaches zero, it is determined that the activated carbon has been saturated with adsorption; record the cumulative adsorption time at saturation, and preprocess the time data to obtain the effective fluctuation range of the cumulative adsorption time;

[0010] M2: Retrieve historical data, mark fully saturated activated carbon data as saturated, and mark the remaining activated carbon data as unsaturated; for unsaturated activated carbon, compare its current cumulative adsorption time with historical data: if both data are the same, calculate the remaining time required for saturation based on the saturation time; if the time is less than a preset threshold, it is determined that it needs to be replaced, and the replacement count is incremented by one; otherwise, it continues to be used; if either of the two data is different, calculate the remaining time required for each item separately, take the average value, and then determine whether to replace it based on the threshold.

[0011] Preferably, the determination step for replacing the analysis module again is as follows:

[0012] N1: Introduce correction coefficients for each influencing factor to obtain the corrected adsorption efficiency. Through the corrected adsorption efficiency Derive the true saturation affected by various influencing factors. In true saturation Exceeding the preset saturation threshold When it is determined that the activated carbon at the corresponding position needs to be replaced, the replacement count is incremented by one; the replacement count is counted, and a replacement signal is generated when the replacement count reaches a preset count threshold.

[0013] N2: Then, mark the unsaturated activated carbon that should be replaced according to the statistical replacement count, and calculate the total adsorption saturation data of the unsaturated activated carbon that should be replaced. ,like The system will then transmit the replacement signal via the wireless transmission module of the intelligent control component to the receiving device of the staff, and issue an alert to remind them to replace the activated carbon at the corresponding location in a timely manner. To determine the number of unadsorbed saturated activated carbons that should be replaced.

[0014] Preferably, one end of the air outlet pipe is a flange air outlet, and the other end of the air outlet pipe is a flange cooling pipe interface.

[0015] Preferably, a temperature probe is provided on one side of the upper end of the outer wall of each of the multiple filter boxes.

[0016] Preferably, a fixed frame is fixedly connected to the lower end of the inner wall of the filter box. Two guide rails are symmetrically provided on the top surface of the fixed frame. A bottom frame is slidably installed on the top surface of the fixed frame through the guide rails. A column is provided at each of the four corners of the top surface of the bottom frame. A partition is provided in the middle of the top surface of the bottom frame. Dovetail grooves are symmetrically opened on both sides of the partition. Each pair of adjacent columns forms a group. Multiple mounting frames are slidably installed on each group of columns. A dovetail block is fixedly connected to one side of the mounting frame and slidably installed in the dovetail groove. An installation groove is opened in the middle of the top surface of the mounting frame. Multiple through holes are evenly opened in the bottom surface of the installation groove. Activated carbon is placed in the bottom surface of the installation groove.

[0017] Preferably, two limiting holes are symmetrically opened on the opposite surface of the mounting frame and the box door, and a positioning hole adapted to the limiting holes is opened on the outer wall of the column. A positioning pin is inserted between the limiting holes and the positioning holes, and a through hole is opened on the outer wall of one end of the positioning pin.

[0018] Preferably, two guide strips are symmetrically arranged on both sides of the top surface of the mounting frame. The top surface of the guide strips has a guide groove, and a guide rod is provided in the guide groove. Two sliding hinge seats are symmetrically sleeved on the guide rod. A return spring sleeved on the guide rod is fixed between the opposite surfaces of the two sliding hinge seats. A fixing block for fixing the return spring is provided in the guide groove. A connecting rod is staggered on the hinge shaft of the two sliding hinge seats. The two connecting rods are X-shaped and a rotating pin passes through the intersection. A fixed hinge seat is hinged to the top of each of the two connecting rods. The fixed end of the fixed hinge seat is bolted to the bottom surface of the adjacent mounting frame.

[0019] The beneficial effects of this invention are:

[0020] 1. By using positioning pins to connect with limiting holes and positioning holes, the height of the mounting frame can be adjusted and fixed. Combined with the sliding cooperation of the guide rails between the bottom frame and the fixed frame, and the sliding connection between the mounting frame and the column, the mounting frame can be adjusted individually or in batches without removing the entire frame. This avoids the generation of a large amount of dust when replacing activated carbon, and also facilitates workers' operation of the mounting frame at higher positions, reducing labor intensity and improving maintenance efficiency. Most importantly, after removing the positioning pins, the connecting rod, in conjunction with the elastic force of the return spring, allows the upper mounting frame to descend slowly, preventing direct fall and dust generation, further optimizing the operating environment and protecting the health of operators. The positioning pins connecting with limiting holes and positioning holes ensure stable positioning of the mounting frame. Combined with the sliding guidance of the dovetail block and dovetail groove, this ensures that the mounting frame does not shift during operation, improving adsorption stability. Ultimately, this solves the problems of inconvenient activated carbon replacement and dust generation in existing organic waste gas treatment devices, comprehensively improving the operational stability, waste gas treatment efficiency, and maintenance convenience of the device.

[0021] 2. The analysis module compares historical data and predicts remaining adsorption time, and combines multi-factor correction coefficients to calculate the true saturation close to the actual working conditions, avoiding misjudgment or omission due to fluctuations in working conditions, and improving the accuracy and rationality of activated carbon replacement; it automatically records and preprocesses the cumulative adsorption time data, marks saturated and unsaturated data with historical data, and scientifically calculates the remaining saturation time by comparing the current data with historical trends, realizing a quantitative judgment on the timing of replacement and reducing human error.

A first desorption pipe 4 is connected to the lower side of each filter box 3. A desorption fan 5 is connected to one end of the first desorption pipe 4 via a connecting pipe. The output end of the desorption fan 5 is connected to the upper side of a catalytic chamber 6 via a pipe. Multiple heat exchange plates are equidistantly arranged on the upper part of the inner wall of the catalytic chamber 6. A catalytic block is located in the middle of the inner wall of the catalytic chamber 6. Multiple heating rods arranged in a serpentine pattern are equidistantly arranged on the lower part of the inner wall of the catalytic chamber 6. A second desorption pipe is connected to the top surface of the catalytic chamber 6. Multiple second desorption valves are equidistantly arranged on one side of the second desorption pipe. Two desorption valves are connected to one side of the upper end of multiple filter boxes 3. The top surfaces of multiple filter boxes 3 are all connected to an air outlet pipe 7 through a second adsorption valve. The inlet pipe 1, filter boxes 3, air outlet pipe 7, and catalytic box 6 are made of 304 stainless steel. The use of 304 stainless steel in the inlet pipe 1, filter boxes 3, air outlet pipe 7, and catalytic box 6 makes them corrosion-resistant and wear-resistant, suitable for complex working conditions of organic waste gas treatment, and extends the service life of the equipment. The desorption fan 5 is a centrifugal desorption fan. The centrifugal desorption fan 5 has a large air volume and stable pressure, which can ensure the efficient delivery of desorbed gas. The heating rod is an intelligent temperature-controlled electric heating rod. The intelligent temperature-controlled electric heating rod has a temperature control function, high heating efficiency, and precise temperature control. It can be combined with a temperature probe to achieve catalytic effect. Precise temperature control within chamber 6 prevents excessively high or low temperatures from affecting the catalytic oxidation effect. The heat exchange fins are made of copper, which offers excellent thermal conductivity and improves temperature uniformity within chamber 6. Inlet pipe 1 ensures stable input of organic waste gas, filter box 3 provides installation space for the adsorption components, first adsorption valve 2, second adsorption valve, and second desorption valve allow for flexible switching of airflow paths, desorption fan 5 provides desorption power, chamber 6 provides the oxidation reaction site, and outlet pipe 7 discharges purified gas. These components together form the basic framework of the device, providing core structural support for the entire process of organic waste gas adsorption-desorption-catalytic oxidation-secondary adsorption. One end of outlet pipe 7 is a flange outlet. The other end of the duct 7 is a flange cooling pipe interface; the flange outlet facilitates the detachable connection of the duct 7 to the subsequent discharge pipe, making installation and maintenance convenient; the flange cooling pipe interface can be connected to a cooling medium, enabling flexible control of the purified gas temperature and avoiding safety hazards caused by high-temperature gas emissions; through the above, the connection flexibility of the device and the safety of exhaust gas emissions are improved; temperature probes are installed on one side of the upper part of the outer wall of multiple filter boxes 3; the temperature probes can monitor the temperature changes inside the filter box 3 in real time, and promptly report the temperature status during the desorption stage, avoiding excessive temperature leading to deactivation of activated carbon 11 or equipment damage, and providing data support for temperature control; through the above, the safety and stability of the device operation are improved, ensuring the adsorption and desorption effects.

[0030] In this invention, reference is made to Figures 2 to 4 As shown, a fixed frame is fixed to the lower end of the inner wall of the filter box 3. Two guide rails are symmetrically arranged on the top surface of the fixed frame. A bottom frame is slidably installed on the top surface of the fixed frame through the guide rails. Columns 8 are provided at the four corners of the top surface of the bottom frame. A partition 9 is provided in the middle of the top surface of the bottom frame. Dovetail grooves are symmetrically opened on both sides of the partition 9. Each pair of adjacent columns 8 forms a group. Multiple mounting frames 10 are slidably installed on each group of columns 8. A dovetail block is fixed to one side of the mounting frame 10 and slidably placed in the dovetail groove. An installation groove is opened in the middle of the top surface of the mounting frame 10. Multiple through holes are evenly opened on the bottom surface of the installation groove. Activated carbon 11 is placed on the bottom surface of the installation groove. The guide rails of the fixed frame and the bottom frame slide together to facilitate the overall assembly. The adsorption assembly can be pulled out for maintenance; the column 8 provides sliding support for the mounting frame 10, and the dovetail block and dovetail groove cooperate to ensure the smooth sliding of the mounting frame 10; the mounting groove of the mounting frame 10 provides space for the activated carbon 11, and the through hole facilitates gas flow; through the above, the activated carbon 11 can be conveniently placed and replaced, improving the maintenance convenience of the adsorption assembly; two limiting holes are symmetrically opened on the opposite surface of the mounting frame 10 and the box door, and the outer wall of the column 8 has a positioning hole that matches the limiting hole. A positioning pin 12 passes between the limiting hole and the positioning hole, and a through hole is opened on the outer wall of one end of the positioning pin 12; the positioning pin 12 passes through the limiting hole and the positioning hole, which can make the mounting frame 10 not... The frame is fixed at the same height to adapt to different operational needs; the perforation facilitates the insertion of cotter pins and other components, preventing the positioning pins 12 from falling off and ensuring the positioning stability of the mounting frame 10; through the above, the height of the mounting frame 10 is flexibly adjusted and securely fixed, improving operational convenience and operational stability; two guide strips 13 are symmetrically arranged on both sides of the top surface of the mounting frame 10, and the top surface of the guide strips 13 has guide grooves. Guide rods are provided in the guide grooves, and two sliding hinge seats 14 are symmetrically sleeved on the guide rods. A pull-back spring sleeved on the guide rod is fixed between the opposite surfaces of the two sliding hinge seats 14. A fixing block for fixing the pull-back spring is provided in the guide groove. A connecting rod 15 is offset on the hinge shaft of 14. The two connecting rods 15 are X-shaped and a rotating pin passes through the intersection. The top of each connecting rod 15 is hinged to a fixed hinge seat. The fixed end of the fixed hinge seat is bolted to the bottom surface of the adjacent mounting frame 10. The guide bar 13 and the guide rod provide sliding guidance for the sliding hinge seat 14. The pull spring, in conjunction with the connecting rod 15, realizes the slow descent of the mounting frame 10, preventing the mounting frame 10 from falling directly and generating dust. The X-shaped connecting rod 15 structure improves the transmission stability, and the fixed hinge seat ensures a firm connection. Through the above, the problem of dust generation during the replacement of activated carbon 11 is solved, the operating environment is optimized, and the health of operators is protected.

[0031] The working principle of this invention is as follows: First, the first adsorption valve 2 and the second adsorption valve are opened, and the second desorption valve is closed. Organic waste gas first enters each filter box 3 through the inlet pipe 1. When the waste gas passes through the activated carbon 11 in the mounting frame 10, the organic pollutants are initially adsorbed by the activated carbon 11, completing the first filtration treatment. When the activated carbon 11 in the filter box 3 is saturated, the desorption and catalytic oxidation stage begins. The first adsorption valve 2 and the second adsorption valve corresponding to that filter box 3 are closed, and the corresponding second desorption valve and desorption fan 5 are opened. Simultaneously, the heating rod in the catalytic box 6 is started to preheat the catalytic box 6, and the heat exchange fins improve the temperature uniformity within the box. The desorption fan 5 extracts the high-concentration organic waste gas generated by desorption in the filter box 3 and sends it into the catalytic box 6. Under the catalytic action of the catalyst block, an oxidation reaction occurs, decomposing into harmless carbon dioxide, water, and a small amount of incompletely purified gas, completing the catalytic oxidation treatment. Subsequently, the gas treated by the catalytic box 6 flows back to the unsaturated filter box 3 through the second desorption pipe for secondary adsorption filtration, further removing residual pollutants. After the secondary adsorption of pollutants is completed, the second adsorption valve of the corresponding filter box 3 is opened, and the purified gas is discharged through the flange outlet of the air outlet pipe 7. If it is necessary to adjust the outlet gas temperature, a cooling medium can be connected through the flange cooling pipe interface of the air outlet pipe 7 to achieve tail gas temperature control. When replacing activated carbon 11, the alternating working mode of multiple filter boxes 3 is used to ensure uninterrupted waste gas treatment. Open the door of the target filter box 3, pull out the positioning pin 12, and the upper mounting frame 10 gradually descends under its own gravity, causing the pull-back spring to open. The rod 15 moves synchronously with the descent of the mounting frame 10, causing the mounting frame 10 to move smoothly along the column 8 and the dovetail groove, avoiding direct fall and dust generation. By adjusting the positioning pin 12 and inserting it into the positioning hole and limit hole at different heights, the height of the mounting frame 10 is fixed for replacement and maintenance. After replacement, the bottom frame is pushed to slide along the guide rail of the fixed frame to reset, the positioning pin 12 is inserted to fix it, and the box door is closed to resume operation. The temperature probe on the outer wall of the filter box 3 monitors the temperature inside the box in real time to prevent abnormal temperature from affecting the operation of the equipment or the performance of the activated carbon 11 during desorption.

[0032] Example 2: Refer to Figure 5 As shown, the filter box 3 is also equipped with an intelligent control component, which includes an analysis module and an alarm module;

[0033] The analysis module determines whether the activated carbon has reached adsorption saturation by plotting the curve of the new activated carbon's adsorption rate over time and analyzing its slope. It also records and preprocesses the cumulative adsorption time data to determine its fluctuation range. Based on historical data, the activated carbon is marked as saturated or unsaturated. The current data of unsaturated activated carbon is compared with historical data to calculate the remaining time to reach adsorption saturation. If this time is less than a preset threshold, replacement is required, and a replacement count is initiated. Correction coefficients are introduced for multiple factors such as temperature, humidity, exhaust gas flow rate, activated carbon particle size, and airflow distribution. Combined with the actual adsorption efficiency, the true saturation under interference is calculated. When the true saturation exceeds a preset threshold, the activated carbon needs replacement, and a replacement count is initiated. Once the replacement count reaches the threshold, a replacement signal is generated and wirelessly transmitted to remind staff to replace the activated carbon promptly.

[0034] Online VOCs concentration sensors are installed at the inlet (at the branch of inlet pipe 1) and outlet (at the branch of outlet pipe 7) of each filter box 3 to collect the VOCs concentration at the inlet of filter box 3 in real time during the adsorption process. and export VOCs concentration Record one set of data per second, and take the average value over one minute as the valid data, then the adsorption efficiency is... Acquire the adsorption rate data of the newly activated carbon at the corresponding location during its use, and plot the adsorption rate data at the corresponding time point in a binary coordinate system of time and adsorption rate. Connect adjacent coordinate points and calculate the slope of the connecting lines. When the slope of the connecting lines approaches zero (0-5%), the activated carbon is determined to be saturated. Record the cumulative adsorption time of the activated carbon at the corresponding location when it is saturated, and preprocess the cumulative adsorption time data to obtain the fluctuation range of the cumulative adsorption time.

[0035] Historical data is acquired, including the cumulative adsorption time and adsorption saturation data of activated carbon at corresponding locations. Data for fully saturated activated carbon is marked as saturated, while data for remaining activated carbon is marked as unsaturated. Data for unsaturated activated carbon is retrieved and compared with the corresponding cumulative adsorption time and adsorption saturation data. If both data points are the same, the remaining time required for the activated carbon to reach adsorption saturation is calculated based on the saturation time in a binary coordinate system. If the remaining time is less than a preset threshold, the unsaturated activated carbon should be replaced, and the replacement count is incremented. Otherwise, the unsaturated activated carbon can continue to be used. If the two data points are different, the remaining time is calculated separately for each data point, and the average of the two remaining times is used to determine whether replacement is necessary.

[0036] Preprocessing: The collected data is sorted according to the collection time, and corresponding items collected at the same time are processed. averaging the data and standard deviation The calculation, and the mean obtained from the calculation. and standard deviation Collect data fluctuation range for corresponding items The system is configured to compare the collected data for a given item with its fluctuation range, mark data outside the fluctuation range as outliers, and record the number of outliers. ,like If the collected data is abnormal, the data will be re-tested; if If outliers are removed, the mean of the remaining corresponding test data after outlier removal is calculated. The calculation, and the mean obtained from the calculation. This refers to the corresponding data detected at the corresponding time.

[0037] Under ideal operating conditions with no interference, the relationship between adsorption efficiency and saturation is as follows: ,in For ideal adsorption efficiency, This represents the maximum adsorption efficiency of the new activated carbon. This represents the actual saturation level. Under actual operating conditions, various influencing factors affect the adsorption efficiency; therefore, correction coefficients for each influencing factor are introduced. The corrected adsorption efficiency is... ,in For sensor error, fluctuation range ;

[0038] exhaust gas temperature Correction factor for impact Exhaust gas humidity Correction factor for impact In exhaust gas flow rate When, correction factor In exhaust gas flow rate When, correction factor In exhaust gas flow rate When, correction factor ;Activated carbon particle size Correction factor for impact Airflow distribution Correction factor for impact ;

[0039] This leads to the deduction of the true saturation affected by various influencing factors. , This represents the adsorption efficiency detected in real time; at true saturation. Exceeding the preset saturation threshold When the system determines that the activated carbon at the corresponding location needs to be replaced, the replacement count is incremented by one. The replacement count is tallied, and a replacement signal is generated when the count reaches a preset threshold. Then, the unsaturated activated carbon identified as needing replacement in the count is marked for replacement, and the total adsorption saturation of the unsaturated activated carbon identified as needing replacement is calculated. ,like The system will then transmit the replacement signal via the wireless transmission module of the intelligent control component to the receiving device of the staff, and issue an alert to remind them to replace the activated carbon at the corresponding location in a timely manner. To determine the number of unadsorbed saturated activated carbons that should be replaced.

For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
