Description

Technical Field

[0001] This invention relates to the field of environmental engineering construction technology, specifically to a tail gas treatment box prepared by 4-chlorobenzoyl chloride. Background Technology

[0002] Environmental engineering construction refers to the process of implementing special projects to treat various types of environmental pollution and restore damaged ecological environments through engineering technology and construction operations, based on environmental design schemes and relevant standards and specifications, so as to achieve the goal of pollutant discharge meeting standards and improving ecological functions. In the preparation process of 4-chlorobenzoyl chloride, exhaust gas is generated. If it is directly emitted, it will seriously pollute the environment. Therefore, exhaust gas treatment boxes are needed to pre-treat the exhaust gas.

[0003] For example, patent CN210385486U discloses a tail gas treatment box for chemical plants. This patent facilitates the opening of the tail gas treatment box by using a telescopic sealing ring, a second positioning block, a sealing frame, a first positioning block, a double-headed positioning screw, a second screw sleeve, and a first screw sleeve in conjunction with each other. This makes maintenance of the tail gas treatment box more convenient, solving the problem of inconvenient opening during maintenance, which consumes a lot of time and leads to inconvenience. It greatly simplifies the maintenance of the tail gas treatment box and is worthy of promotion. However, in actual operation, since tail gas usually contains harmful gases, directly separating the box to remove the internal filter screen for maintenance can cause residual harmful gases inside the box to be released directly, polluting the surrounding environment. Summary of the Invention

[0004] The purpose of this invention is to provide a tail gas treatment box prepared by 4-chlorobenzoyl chloride to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a tail gas treatment box for the preparation of 4-chlorobenzoyl chloride, comprising a box body and a first protective component. A cover plate is provided at the center of the top of the box body, and a limiting frame is fixed at the bottom of the cover plate. A filter component is provided inside the limiting frame. A connecting buckle is provided at the top of the box body, and a connecting block is slidably connected inside the connecting buckle. The first protective component is provided at both ends of the limiting frame, and the first protective component includes a pulley seat. The bottom of the connecting block abuts against the pulley seat, and a synchronizing rod is fixed at the bottom of the pulley seat. A compression spring is sleeved on the outer side of the upper end of the synchronizing rod, and a movable sealing plate is provided on the outer side of the middle part of the synchronizing rod. A fixed sealing plate is slidably connected to one side of the movable sealing plate. A second protective component is symmetrically arranged inside the box body, and the structure of the second protective component is consistent with the structure of the first protective component.

[0006] Furthermore, the fixed sealing plate has an L-shaped cross-section and is fixedly connected to the limiting frame.

[0007] Furthermore, the synchronizing rod is slidably connected to the fixed sealing plate, and the movable sealing plates are arranged in an array along the length of the synchronizing rod, with each movable sealing plate corresponding to a fixed sealing plate.

[0008] Furthermore, the filter assembly includes a filter screen, with the filter screen embedded inside one end of the limiting frame, an activated carbon filter plate placed in the center of the limiting frame, and a photocatalytic filter plate disposed inside the other end of the limiting frame.

[0009] Furthermore, a control component is connected to the top center of the cover plate, and the control component includes a handle. The top of the cover plate is provided with a handle, and a rotating seat is placed at the bottom of the handle. The lower two ends of the rotating seat are rotatably connected to a drive plate, and the end of the drive plate is rotatably connected to a slider. The two sides of the slider are rotatably connected to a synchronization plate, and the end of the synchronization plate is rotatably connected to a connecting rod.

[0010] Furthermore, the rotating seat and the cover plate are rotatably connected by a dynamic seal, and the slider is slidably connected to the cover plate.

[0011] Furthermore, the connecting rod is slidably connected to the cover plate, and the connecting rod is fixedly connected to the connecting block.

[0012] Furthermore, a stabilizing component is provided at one end of the handle, and a stop block is abutted against the other side of the handle, and the stop block is fixedly connected to the cover plate. The stabilizing component includes a torsion spring shaft. A torsion spring shaft is installed on the upper side of the handle, and a swing arm is provided on the outer side of the torsion spring shaft. The swing arm is C-shaped, and a lifting sleeve is slidably connected to the lower outer side of the swing arm. A pin is fixed at the bottom of the lifting sleeve, and the pin is slidably connected to the handle. A positioning hole is provided on the top of the cover plate, and there are two positioning holes.

[0013] Furthermore, a detection component is provided on the outside of the cover plate, and the detection component includes a sealing ring. The sealing ring is fitted into the outer end of the bottom surface of the box, and a detection channel is opened at the outer end of the bottom surface of the box. A suction tube is placed inside the detection channel, and one end of the suction tube is connected to a detection box. The detection box is fixedly connected to the cover plate. Waterproof and breathable membranes are placed at the upper and lower ends inside the detection box, and a connecting pipe is connected to the upper side of the detection box. One end of the connecting pipe is connected to an air cylinder, and a piston rod is slidably connected inside the air cylinder. A limiting plate is sleeved on the outer side of one end of the piston rod, and the limiting plate is fixedly connected to the cover plate. A return spring abuts against one side of the limiting plate, and a driving block abuts against one end of the return spring.

[0014] Furthermore, the drive block is fixedly connected to the piston rod, and the drive block abuts against the handle.

[0015] This invention provides a tail gas treatment box prepared from 4-chlorobenzoyl chloride, which has the following beneficial effects:

[0016] 1. This invention enables the simultaneous opening of the movable sealing plates of the first and second protective components by inserting the connecting block into the connecting buckle, allowing exhaust gas to enter. Conversely, when disassembly is required for maintenance to release the lock between the connecting block and the connection port, the compression spring drives the synchronizing rod to automatically reset all movable sealing plates, which then fit tightly against the fixed sealing plates, forming a reliable sealing barrier at both ends of the housing and the limiting frame. This automatic linkage mechanism of "opening upon connection and sealing upon disconnection" fundamentally eliminates the risk of toxic and harmful exhaust gas leaking from the inside of the equipment during disassembly and maintenance, greatly improving the health and safety of operators and environmental compliance.

[0017] 2. By pressing the swing arm and turning the handle, the locking of all connecting buckles and connecting blocks can be released at once, realizing the quick disassembly of the cover plate. This simplifies the traditional tedious step-by-step operation. After releasing the thumb, the swing arm automatically resets and locks under the action of the torsion spring, ensuring the stability of the mechanism and preventing accidental loosening. Installation is also convenient and efficient, effectively improving the overall maintenance efficiency and operation convenience of the equipment.

[0018] 3. When installing the cover plate, rotating the handle to a specific position will cause the drive block to move the piston rod inside the air cylinder, thereby creating a negative pressure in the detection system. If the sealing ring is not sealed tightly, external gas will enter the detection liquid through the detection channel and generate large bubbles or small bubbles will remain for a long time. This enables real-time self-checking of the sealing performance during the installation process, allowing for timely detection and handling of problems, and significantly improving the safety and reliability of the equipment operation.

Detailed Implementation

[0028] Please see Figures 1 to 5The present invention provides a technical solution: a tail gas treatment box for the preparation of 4-chlorobenzoyl chloride, comprising a box body 1 and a first protective component 7. A cover plate 2 is provided at the center of the top of the box body 1, and a limiting frame 3 is fixed at the bottom of the cover plate 2. A filter component 4 is provided inside the limiting frame 3, the filter component 4 including a filter screen plate 401. The filter screen plate 401 is embedded inside one end of the limiting frame 3, and an activated carbon filter plate 402 is placed in the center of the limiting frame 3. A photocatalytic filter plate 403 is provided inside the other end of the limiting frame 3. A connecting buckle 5 is provided at the top of the box body 1, and a connecting block 6 is slidably connected inside the connecting buckle 5. The first protective component 7 is provided at both ends of the limiting frame 3, and the first protective component 7 includes a pulley seat 701 and a connecting block. The bottom of 6 is abutted against a pulley seat 701, and a synchronizing rod 702 is fixed to the bottom of the pulley seat 701. A compression spring 703 is sleeved on the outer side of the upper end of the synchronizing rod 702, and a movable sealing plate 704 is installed on the outer side of the middle part of the synchronizing rod 702. A fixed sealing plate 705 is slidably connected to one side of the movable sealing plate 704. The fixed sealing plate 705 has an L-shaped cross section and is fixedly connected to the limiting frame 3. The synchronizing rod 702 is slidably connected to the fixed sealing plate 705. The movable sealing plates 704 are arranged in an array along the length direction of the synchronizing rod 702, and the movable sealing plates 704 and the fixed sealing plates 705 correspond one-to-one. The second protective component 8 is symmetrically arranged inside the housing 1, and the structure of the second protective component 8 is the same as the structure of the first protective component 7.

[0029] The specific operation is as follows: When treating exhaust gas, the connecting block 6 presses against the pulley seat 701, causing the compression spring 703 to be in a contracted state. At this time, the movable sealing plate 704 can be moved to the side of the fixed sealing plate 705 by the synchronous rod 702, allowing the airflow to pass through the opening formed by the fixed sealing plate 705. Therefore, the exhaust gas can pass through the second protective component 8 and the first protective component 7 and enter the interior of the limiting frame 3. The dust impurities and some harmful gases in the exhaust gas are filtered by the filter screen plate 401, the activated carbon filter plate 402, and the photocatalytic filter plate 403. It is then necessary to remove the limiting frame 3. When maintaining and cleaning the internal filter assembly 4, removing the connecting block 6 from the top of the pulley seat 701 allows space for the synchronous rod 702 to move upwards. At this time, the compression spring 703, through the synchronous rod 702, drives all the movable sealing plates 704 to press tightly against the fixed sealing plate 705 above them, thus simultaneously sealing both ends of the inside of the housing 1 and both ends of the limiting frame 3. This prevents residual exhaust gas inside the housing 1 from directly dispersing and polluting the surrounding environment after the limiting frame 3 is removed. After the limiting frame 3 is moved into the washing pool, the movable sealing plates 704 are opened, allowing water to flow into the interior. The filter assembly 4 is soaked and cleaned. The immersion process neutralizes the acidic corrosive gases (such as HCl and Cl2) adsorbed on the filter media, preventing these harmful gases from being released during filter plate disassembly. This provides a safe basis for subsequent fine maintenance. Then, the bolts on the bottom plate of the limiting frame 3 are removed, and the filter plates are thoroughly cleaned and maintained, improving operational safety. Therefore, when cleaning or replacing the filter media is required, only the entire cover plate 2 assembly needs to be disassembled and replaced first, allowing the equipment to quickly resume operation and greatly shortening maintenance downtime. This is particularly suitable for continuous production conditions. The modules to be replaced... Safe and thorough cleaning and maintenance can be carried out in a dedicated area. In addition, the opening and closing of the first protective component 7 and the second protective component 8 are controlled by the linkage of the connecting block 6. When the connecting block 6 is inserted into the connecting buckle 5, the connecting block 6 can push the compression spring 703 to move down, and the first protective component 7 and the second protective component 8 will be in the open state. When the connecting block 6 is separated from the connecting buckle 5 and the limiting frame 3 is removed, the connecting block 6 will also be separated from the pulley seat 701, and the first protective component 7 and the second protective component 8 will be in the closed state. No additional personnel control is required, which helps to improve the convenience of operation.

[0030] Please see Figures 6 to 7A control component 9 is connected to the center of the top of the cover plate 2. The control component 9 includes a handle 901. The handle 901 is located on the top of the cover plate 2, and a rotating seat 902 is placed at the bottom of the handle 901. A drive plate 903 is rotatably connected to both ends of the lower part of the rotating seat 902, and a slider 904 is rotatably connected to the end of the drive plate 903. The rotating seat 902 and the cover plate 2 are rotatably connected by a dynamic seal, and the slider 904 is slidably connected to the cover plate 2. Synchronizing plates 905 are rotatably connected to both sides of the slider 904, and a connecting rod 906 is rotatably connected to the end of the synchronous plate 905. The connecting rod 906 is slidably connected to the cover plate 2, and the connecting rod 906 is fixedly connected to the connecting block 6. One end of the handle 901 is provided with a stabilizing component 10, and the other end of the handle 901 is abutted against a stop block 11, and the stop block 11 is fixedly connected to the cover plate 2. The stabilizing component 10 includes a torsion spring shaft 1001. The torsion spring shaft 1001 is installed on the upper side of the handle 901, and a swing arm 1002 is provided on the outer side of the torsion spring shaft 1001. The swing arm 1002 is C-shaped, and a lifting sleeve 1003 is slidably connected to the lower outer side of the swing arm 1002. A pin 1004 is fixed at the bottom of the lifting sleeve 1003, and the pin 1004 is slidably connected to the handle 901. The top of the cover plate 2 is provided with a positioning hole 1005, and there are two positioning holes 1005.

[0031] The specific operation is as follows: During the disassembly of cover plate 2, when the operator holds handle 901, they can press the swing arm 1002 with their thumb. At this time, the other end of the swing arm will pull the pin 1004 through the lifting sleeve 1003, moving it out of the positioning hole 1005 below, thus releasing the rotation restriction between handle 901 and cover plate 2. Then, by rotating handle 901, the rotating seat 902 will pull the slider 904 through the drive plate 903, causing it to move towards the rotating seat 902 under the limit of the groove inside the cover plate 2. The slider 904 will also pull the connecting rod 906 through the synchronization plate 905, thereby simultaneously driving all the connecting buckles 5 and connecting blocks 6 to separate. This "one-click decoupling" design simplifies the tedious steps that traditionally require individual operation into a continuous action, significantly shortening the disassembly time of cover plate 2 and greatly improving maintenance efficiency. After the thumb is turned, the torsion spring shaft 1001 will drive the swing arm 1002 to reset, so that the pin 1004 is inserted into another positioning hole 1005, and the adjusted position is quickly locked. This automatic locking mechanism ensures that the handle 901 is fixed in the non-operational state, preventing the mechanism from loosening due to accidental contact, and enhancing the reliability of the equipment. When the handle 901 is turned, it can be quickly limited by the stop block 11, which effectively avoids problems such as misalignment of the hole and one-sided jamming, making the installation process equally smooth and efficient. When installing the cover plate 2, the connecting buckle 5 will first align with the grooves at the four corners of the bottom of the cover plate 2 and pre-fit. Then, press the upper end of the swing arm 1002 and turn the handle 901. Similarly, all the connecting buckles 5 can be inserted into the connecting block 6 at the same time. The entire disassembly and assembly process can be completed with only one hand, thereby improving the convenience of equipment maintenance.

[0032] Please see Figure 1 , Figure 2 and Figure 8 The cover plate 2 is provided with a detection component 12, which includes a sealing ring 1201. The sealing ring 1201 is fitted into the outer end of the bottom surface of the box 1, and a detection channel 1202 is opened at the outer end of the bottom surface of the box 1. A suction tube 1203 is placed inside the detection channel 1202, and one end of the suction tube 1203 is connected to a detection box 1204. The detection box 1204 is fixedly connected to the cover plate 2. Waterproof and breathable membranes 1205 are placed at the upper and lower ends inside the detection box 1204, and the upper side of the detection box 1204 is connected to... A connecting pipe 1206 is connected to an air cylinder 1207 at one end, and a piston rod 1208 is slidably connected inside the air cylinder 1207. A limiting plate 1209 is sleeved on the outer side of one end of the piston rod 1208, and the limiting plate 1209 is fixedly connected to the cover plate 2. A return spring 1210 abuts against one side of the limiting plate 1209, and a driving block 1211 abuts against one end of the return spring 1210. The driving block 1211 is fixedly connected to the piston rod 1208, and the driving block 1211 abuts against the handle 901.

[0033] The specific operation is as follows: During installation, when the cover plate 2 is attached to the housing 1, the sealing performance between them can be enhanced by the two sealing rings 1201 to prevent leakage during exhaust gas treatment. Then, when the handle 901 is turned so that the connecting block 6 is inserted into the connecting buckle 5, one end of the handle 901 will contact the drive block 1211. Subsequently, when the connecting block 6 continues to slide in the connecting buckle 5, the handle 901 will push the drive block 1211, causing it to squeeze the return spring 1210 on the side of the limiting plate 1209, and drive the piston rod 1208 to slide inside the air cylinder 1207. This allows the inside of the detection box 1204 to be drawn into a negative pressure state through the connecting pipe 1206. The inside of the detection box 1204 will then be connected to the inside of the detection channel 1202 through the connecting pipe 1206. Since the sealing ring 1201 is not properly sealed after installation, a large amount of airflow will flow into the detection channel 1202 and enter the lower end of the detection box 1204 through the suction tube 1203. At this time, the waterproof and breathable membrane 1205 contains red transparent detection liquid. When the airflow enters and passes through the detection liquid, it will form large bubbles. After the cover plate 2 is installed, if large bubbles are found to continuously appear in the detection liquid in the detection box 1204 or small bubbles are found to float for a long time, it indicates that the sealing performance of the sealing ring 1201 is not good, so that the sealing ring 1201 can be replaced or maintained in time. This "installation and testing" mechanism transforms the sealing check from a process that requires additional tools and steps into a built-in process that is automatically executed every time the cover plate 2 is installed, ensuring the safe use of the equipment.

[0034] In summary, the exhaust gas treatment box prepared with 4-chlorobenzoyl chloride is used as follows:

[0035] First, during disassembly, close the valves on the relevant pipelines. Then, the operator holds handle 901 and presses the swing arm 1002 with their thumb. At this time, the other end of the swing arm will pull the pin 1004 through the lifting sleeve 1003, moving it out of the positioning hole 1005 below, releasing the rotation restriction between handle 901 and cover plate 2. Then, rotate handle 901, and the rotating seat 902 will pull the slider 904 through the drive plate 903, causing it to move towards the rotating seat 902 under the limit of the groove inside the cover plate 2. The slider 904 will also pull the connecting rod 906 through the synchronization plate 905, thereby simultaneously driving all the connecting buckles 5 and connecting blocks 6 to separate. During this process... By removing the connecting block 6 from the top of the pulley seat 701, space can be provided for the synchronous rod 702 to move upward. At this time, the compression spring 703 drives all the movable sealing plates 704 to press against the fixed sealing plate 705 above them through the synchronous rod 702, which can simultaneously seal the two ends inside the box 1 and the two ends inside the limiting frame 3. When the thumb is released, the torsion spring shaft 1001 will drive the swing arm 1002 to reset, so that the pin 1004 is inserted into another positioning hole 1005, and the position of the handle 901 after adjustment is quickly locked, thereby preventing the exhaust gas remaining inside the box 1 from being directly diffused after the limiting frame 3 is removed, which would pollute the surrounding environment.

[0036] Secondly, when installing the new cover plate 2 assembly, the connecting buckle 5 will first align and pre-fit with the grooves at the four corners of the bottom of the cover plate 2. At the same time, the sealing performance between the cover plate 2 and the box 1 is enhanced by the two sealing rings 1201 to prevent leakage during the exhaust gas treatment process. Then, press the upper end of the swing arm 1002 and turn the handle 901. Similarly, all the connecting buckles 5 can be inserted into the connecting block 6 at the same time. During the process of the connecting block 6 being inserted into the connecting buckle 5, the connecting block 6 can push the compression spring 703 to move down. The movable sealing plate 704 can be controlled to move to the side of the fixed sealing plate 705 through the synchronous rod 702. The first protective component 7 and the second protective component 8 will be in an open state. When the connecting block 6 is separated from the connecting buckle 5 and the limiting frame 3 is removed, the connecting block 6 will be separated from the pulley seat 701. The first protective component 7 and the second protective component 8 will be in a closed state. No additional control by personnel is required, which helps to improve the convenience of operation.

[0037] Then, when the connecting block 6 is inserted into one end of the connecting buckle 5, one end of the handle 901 will contact the drive block 1211. Subsequently, as the connecting block 6 continues to slide within the connecting buckle 5, the handle 901 will push the drive block 1211, causing it to press the reset spring 1210 on the side of the limiting plate 1209, and drive the piston rod 1208 to slide inside the air cylinder 1207. This allows the inside of the detection box 1204 to be drawn into a negative pressure state through the connecting tube 1206, and the inside of the detection box 1204 is connected to the inside of the detection channel 1202 through the connecting tube 1206. Therefore, after installation, if the sealing ring 1201 is not sealed tightly, a large amount of airflow will flow into the detection channel 1202 and enter the lower end of the detection box 1204 through the suction tube 1203. At this time, the waterproof and breathable membrane 1205 contains red transparent detection liquid. When the airflow enters and passes through the detection liquid, it will form bubbles. After the cover plate 2 is installed, if large bubbles are found to continuously appear in the detection liquid in the detection box 1204 or small bubbles are found to float for a long time, it indicates that the sealing performance of the sealing ring 1201 is not good, so that the sealing ring 1201 can be replaced or maintained in time.

[0038] Finally, the valve on the equipment pipeline is opened, and the airflow passes through the opening formed between the fixed sealing plates 705. Therefore, the exhaust gas can pass through the second protective component 8 and the first protective component 7 and enter the interior of the limiting frame 3. The exhaust gas is filtered by the filter screen plate 401, the activated carbon filter plate 402 and the photocatalytic filter plate 403 to remove dust impurities and some harmful gases. After the equipment is working normally, the personnel move the disassembled limiting frame 3 into the water washing tank and then open the movable sealing plate 704 to allow water to soak and clean the internal filter components 4. The water immersion process can neutralize the acidic corrosive gases (such as HCl and Cl2) adsorbed on the filter material, preventing these harmful gases from being released when the filter plates are disassembled. Subsequently, the bolts of the bottom plate of the limiting frame 3 are removed to thoroughly clean and maintain the filter plates, improving the safety of operation.
