Description

Technical Field

[0001] The present invention relates to the technical field of tail gas treatment, and more particularly to a tail gas treatment device after distillation of a furanol product. Background Art

[0002] Furanol is a colorless liquid that is soluble in organic solvents such as dichloromethane, toluene, alcohol, and ether, but insoluble in water. In the pesticide field, it is mainly used as a dedicated intermediate for the production of the pesticide carbofuran. In the pharmaceutical field, furanol and its derivatives have antibacterial, anti-inflammatory, and antioxidant biological activities and are often used in drug synthesis. During the distillation process, tail gas is generated. This tail gas may contain unreacted raw materials, by-products, solvent vapors, and other volatile organic compounds. Therefore, existing tail gas treatment devices still have problems, as follows: 1. When treating large amounts of tail gas, a single-layer adsorbent has limited adsorption capacity and is prone to saturation. The single-layer adsorbent bears a large load, and the adsorbed pollutants may cause the adsorbent to quickly saturate or degrade. When the adsorbent is saturated, the pollutants in the tail gas cannot be effectively removed, resulting in tail gas emissions failing to meet expected environmental standards. Second, the adsorbent will reach saturation after a period of use and needs to be replaced. Replacing the adsorbent usually requires a period of downtime, which will affect production efficiency. Production interruptions will lead to a decrease in output. Especially in continuous production processes, the downtime when replacing the adsorbent may cause large-scale production stagnation, thereby affecting the overall operation of the factory.

[0003] Therefore, the present invention urgently needs a tail gas treatment device after the distillation of furanol products. Summary of the Invention

All other embodiments obtained by ordinary technicians in this field without making creative work fall within the scope of protection of the present invention.

[0019] Reference Figures 1 to 4 The present invention provides a tail gas treatment device after distillation of a furanol product, comprising an outer frame mechanism 1, an inner mechanism 2, a replacement mechanism 3, and a monitoring mechanism 4. The inner side of the outer frame mechanism 1 is fixedly connected to the side of the inner mechanism 2, the inner side of the inner mechanism 2 is engaged with the side of the replacement mechanism 3, the side of the inner mechanism 2 is fixedly connected to the side of the monitoring mechanism 4, and the side of the monitoring mechanism 4 is connected to the bottom end of the replacement mechanism 3. The internal mechanism 2 includes an internal frame 201 and a cleaning rod 205. The internal frame 201 has a placement groove 202 formed on its inner side. A gear ring 203 is fixedly connected to the inner side of the placement groove 202. The side surface of the internal frame 201 is fixedly connected to the inner side of the external frame mechanism 1. The replacement mechanism 3 includes a first placement frame 31 and a second placement frame 311. The side of the first placement frame 31 is fixedly connected with a fixed tooth 313, and the side of the fixed tooth 313 is engaged with the side of the gear ring 203. A ventilation hole 312 is opened at the bottom end of the first placement frame 31, and the ventilation hole 312 can pass exhaust gas. A certain amount of activated carbon is placed on the inside of the first placement frame 31.

[0020] Among them, the outer frame mechanism 1 includes an outer fixed frame 101 and an upper collecting cover 102, the top of the outer fixed frame 101 is fixedly connected to the bottom end of the upper collecting cover 102, the top of the upper collecting cover 102 is fixedly connected to the air outlet pipe 103, the top of the upper collecting cover 102 is fixedly connected to the bottom end of the replacement mechanism 3, and a feeding port 104 is opened on the side of the outer fixed frame 101, and the inner side of the feeding port 104 is connected to the cabinet door 108, and the side of the cabinet door 108 is connected to the side of the first placement frame 31.

[0021] Among them, the side of the outer fixed frame 101 is fixedly connected to the air intake pipe 105, the top of the upper collecting cover 102 is provided with a sliding groove 106, the inner side of the sliding groove 106 is connected to the side of the replacement mechanism 3, and the side of the air intake pipe 105 is connected to the side of the hydrolysis chamber 107.

[0022] Among them, the side of the cleaning rod 205 is connected to the side of the first placement frame 31, the inner side of the cleaning rod 205 is connected to the rotating rod 206, the top of the rotating rod 206 is fixedly connected to the side of the built-in frame 201, the top of the rotating rod 206 is fixedly connected to the side of the external fixed frame 101, and a movable groove 204 is opened on the side of the built-in frame 201. The side of the movable groove 204 is connected to the side of the first placement frame 31, and the bottom end of the built-in frame 201 divides the bottom end of the external fixed frame 101 into a hydrolysis bin 107.

[0023] The tail gas after distillation is introduced from the air inlet pipe 105, and an aqueous solution is placed in the hydrolysis chamber 107 to absorb the harmful substances dissolved in water in the tail gas. A check valve is provided at the connection between the air inlet pipe 105 and the outer fixed frame 101 to control the liquid in the hydrolysis chamber 107 from flowing out along the air inlet pipe 105. After the tail gas is introduced, since the density of the gas is less than that of water, the tail gas that is insoluble in water continues to rise after passing through the water surface. An inner frame 201 is placed inside the outer fixed frame 101, dividing the space of the outer fixed frame 101 into two parts. The inner side of the inner frame 201 does not contact the tail gas, so the tail gas will continue to rise through the ventilation holes 312 opened at the bottom end of the second placement frame 311, and the activated carbon inside the second placement frame 311 will adsorb the organic matter in the tail gas. A first organic matter sensor 401 is placed above the second placement frame 311 to detect the tail gas passing through its surface. If there is no response, the tail gas continues to rise and is discharged from the air outlet pipe 103. When the first organic matter sensor 401 detects that there are still organic matter in the exhaust gas, it closes the switch and lights up the detection light. However, there is a spare first placement frame 31 above the first organic matter sensor 401 to continue to adsorb the remaining organic matter. When the activated carbon inside the first placement frame 31 is working, the second placement frame 311 is moved by moving the control rod 333 to replace the activated carbon inside the second placement frame 311. The replaced activated carbon can be restored to its activity through chemical or physical means for easy recycling next time. When the second placement frame 311 and the first placement frame 31 move inside the outer fixed frame 101, the moving groove 204 opened on the side of the inner frame 201 provides space for them, but the moving groove 204 is not opened on the other side of the inner frame 201. In order to prevent the exhaust gas from entering the inner side of the inner frame 201 and being discharged into the outside air, when the second placement frame 311 moves to the inner side of the inner frame 201, the other side of the second placement frame 311 is still blocked at the moving groove 204 to prevent the exhaust gas from spreading everywhere. The cleaning rod 205 placed behind the moving groove 204 will wipe the water mist attached to the bottom of the second placement frame 311 when it moves.

[0024] Reference Figures 5 to 8 The side of the second placement frame 311 is fixedly connected to a moving ring 324, the inner side of the moving ring 324 is connected to a moving rod 32, the side of the moving rod 32 is connected to a T-shaped fixed shaft 321, the side of the T-shaped fixed shaft 321 is fixedly connected to the side of the first placement frame 31, a spiral groove 325 is opened on the side of the moving rod 32, the side of the spiral groove 325 is threadedly connected to the inner side of the moving ring 324, and the bottom end of the spiral groove 325 is fixedly connected to a support pad 326.

[0025] Among them, the top of the T-shaped fixed shaft 321 is fixedly connected to the control plate 322, the top of the control plate 322 is fixedly connected to the second support plate 327, the inner side of the second support plate 327 is connected to the control rod 333, the top of the moving rod 32 is connected to the support pad 326, the top of the support pad 326 is fixedly connected to the first support plate 323, the side of the first support plate 323 is connected to the side of the control rod 333, and the side of the control plate 322 is connected to the inner side of the sliding groove 106.

[0026] Among them, the side of the control rod 333 is connected to the guide frame 33, the side of the guide frame 33 is provided with an annular slide groove 331, the inner side of the annular slide groove 331 is connected to the side of the control rod 333, the top of the annular slide groove 331 is provided with a vertical slide groove 332, the bottom end of the guide frame 33 is fixedly connected to the load-bearing rod 334, and the bottom end of the load-bearing rod 334 is fixedly connected to the top of the upper collection cover 102.

[0027] Among them, the monitoring mechanism 4 includes a first organic matter sensor 401 and a second organic matter sensor 402. The side of the first organic matter sensor 401 is fixedly connected to a support rod 403, and the side of the support rod 403 is fixedly connected to the inner side of the outer fixed frame 101. The fixation of the second organic matter sensor 402 is similar to that of the first organic matter sensor 401.

[0028] When the second placement frame 311 is moved to the inside of the built-in frame 201 to replace the activated carbon, the exhaust gas is adsorbed by the first placement frame 31 for organic matter. The movement of the second placement frame 311 and the first placement frame 31 is achieved by the control rod 333. When the control rod 333 moves the moving rod 32 up and down, the second support plate 327 at the top of the control plate 322 is equivalent to the fulcrum of the lever, so the control plate 322 will not move up and down with the moving rod 32. Similarly, the support pads 326 at the top of the moving rod 32 are socketed, so when the control plate 322 rotates, it will not drive the moving rod 32 to rotate, and the movement between the second placement frame 311 and the first placement frame 31 does not interfere with each other.

[0029] The working principle of the present invention is as follows: when the exhaust gas to be treated is injected into the inner side of the outer fixed frame 101 from the air inlet pipe 105, an inner frame 201 is placed on the inner side of the outer fixed frame 101 to divide it into a hydrolysis chamber 107 and the inner area of ​​the inner frame 201, and an aqueous solution is placed in the hydrolysis chamber 107 to dissolve the water-soluble impurities in the exhaust gas. When the exhaust gas comes out of the hydrolysis chamber 107 and reaches the second placement frame 311, activated carbon is placed on the inner side of the second placement frame 311 to adsorb and treat the organic matter in the exhaust gas. After being absorbed by the second placement frame 311 and the first placement frame 31, the exhaust gas is discharged through the outlet pipe 103 to the gas detection device for emission standard detection.

[0030] A first organic matter sensor 401 is placed between the second placement frame 311 and the first placement frame 31 to detect whether the adsorption force of the activated carbon inside the second placement frame 311 has reached saturation. When the first organic matter sensor 401 above the second placement frame 311 detects organic matter, it will close the switch and light up the alarm light. After the light is on, the moving rod 32 can be manipulated to move the second placement frame 311. Through the up and down movement of the moving rod 32, the spiral groove 325 on the side of the moving rod 32 is threadedly connected to the moving ring 324, so the moving rod 32 The movement drives the rotation of the movable ring 324, and the second placement frame 311 fixed on the side of the movable ring 324 can be moved to the inside of the internal frame 201. When the second placement frame 311 is moved and fixed, the cabinet door 108 on the side of the feeding port 104 is opened, and the activated carbon inside the second placement frame 311 is replaced. The outer fixed frame 101 is then sealed again, and the movable rod 32 is moved back to its original position, and the second placement frame 311 is reset. When the second placement frame 311 works again, the first organic matter sensor 401 automatically disconnects the power supply and turns off the alarm light after detecting no organic matter. When the second placement frame 311 is replacing the built-in activated carbon, the first placement frame 31 is used to adsorb the subsequent exhaust gas. When the first organic matter sensor 401 and the second organic matter sensor 402 simultaneously detect organic matter and turn on the alarm light, the air intake function of the intake pipe 105 will be stopped, and the activated carbon inside the first placement frame 31 and the second placement frame 311 needs to be replaced. The first placement frame 31 and the second placement frame 311 are moved by controlling the control rod 333. When the control rod 333 slides inside the annular slide groove 331, it drives the T-shaped fixed shaft 321 fixed at the bottom end of the control plate 322 to rotate on the side of the moving rod 32. The support pad 326 fixed at the bottom end of the first support plate 323 is sleeved with the moving rod 32, so the rotation of the first support plate 323 will not drive the moving rod 32 to rotate, so the movement of the first placement frame 31 and the second placement frame 311 does not affect each other. Therefore, when the control rod 333 slides inside the annular groove 331, the first placement frame 31 rotates inside the outer fixed frame 101, and the fixed teeth 313 on the side of the first placement frame 31 engage with the gear ring 203 from the side, moving the first placement frame 31 to the inside of the built-in frame 201 to replace the activated carbon, and the control rod 333 slides up and down on the inside of the vertical groove 332, driving the moving rod 32 to move up and down, so that the second placement frame 311 rotates to the inside of the built-in frame 201. A moving groove 204 that matches the height of the first placement frame 31 is opened on the side of the built-in frame 201, so the side of the second placement frame 311 can also be a sealed door at the built-in frame 201.

[0031] When the second placement frame 311 and the first placement frame 31 are moved to the inner side of the built-in frame 201, a cleaning rod 205 is placed on the side of the moving groove 204. The second placement frame 311 rolls on the side of the cleaning rod 205 to wipe off the impurities adsorbed on the bottom of the second placement frame 311 to prevent secondary pollution to the exhaust gas treatment. Similarly, the item is also placed on the bottom of the first placement frame 31 when it enters and exits the moving groove 204 for cleaning.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
