Description

Technical Field

[0001] The present invention relates to the technical field of tail gas treatment, and in particular to a tail gas treatment device for chemical equipment. Background Art

[0002] In the process of producing and processing products, enterprises inevitably generate a large amount of waste gas or tail gas emissions. These emissions often contain a large amount of acidic or alkaline substances. If these tail gases are discharged directly into the atmosphere without treatment, they will cause serious air pollution to the surrounding environment of the enterprise. In order to reduce this pollution, most companies will use tail gas adsorption devices to purify the gas. Such measures are intended to ensure that the emitted gases meet the emission standards stipulated by the environmental protection department. However, although existing tail gas adsorption devices can purify these harmful gases to a certain extent, they generally have some problems. Existing activated carbon adsorption devices generally use absorption towers or absorption cans, which have problems such as large footprint, large airflow resistance, low filtration efficiency, etc., and the replacement of activated carbon is extremely troublesome. In particular, the containers or boxes for storing activated carbon are easily damaged and extremely inconvenient to replace.

[0003] A Chinese patent document with authorization publication number CN105363317B discloses an activated carbon adsorption device, comprising a rectangular hollow box, an air inlet pipe connected to one end of the box, and an air outlet pipe connected to the other end of the box. The box is divided into multiple rectangular filter cavities by horizontally arranged plywood. Multiple drawers are slidably arranged in the filter cavity, and a sealed drawer structure is adopted to enable the replacement of activated carbon.

[0004] In current industrial applications, during the operation of the activated carbon adsorption device, the side of the activated carbon brick that first contacts the exhaust gas in the exhaust treatment system, that is, the windward side, often encounters blockage problems. This problem is mainly attributed to several key factors. First, the exhaust gas may contain various particulate matter, such as dust, paint mist, etc. When these particulate matter comes into direct contact with the activated carbon layer, they will quickly accumulate in the pores on the windward side. This physical blockage phenomenon will significantly reduce the adsorption capacity of the activated carbon. Because the pores are blocked, it is difficult for gas molecules to enter the activated carbon for effective adsorption. In addition, the blockage will make it difficult for the airflow to pass smoothly through the activated carbon layer, thereby affecting the efficiency and performance of the entire exhaust treatment system. Summary of the Invention

[0005] The present invention provides an exhaust gas treatment device for chemical equipment, which aims to solve the problem in the related art that when particulate matter contained in the exhaust gas directly contacts the activated carbon layer, these impurities will quickly accumulate in the gaps on the windward side, causing physical blockage.

[0006] An exhaust gas treatment device for chemical equipment includes a box body, wherein the top and bottom ends of the box body are respectively provided with an air outlet and an air inlet. A filter assembly is installed in the box body, and the filter assembly divides the box body into an air inlet cavity and an air outlet cavity. The filter assembly includes:

[0007] The mounting frame is provided with a plurality of inclined diversion channels, the two ends of the diversion channels are respectively connected to the air inlet cavity and the air outlet cavity, and the height of the front end of the diversion channel is smaller than the height of the rear end;

[0008] Multiple groups of carbon frames, each group having at least two carbon frames, and the multiple groups of carbon frames are slidably installed in multiple branch channels, the rear side of the carbon frame is open, and the front side has multiple hollow areas and dense areas evenly distributed vertically. The upper and lower sides of the carbon frame are respectively in contact with the upper and lower walls of the branch channel, and the inner side of the dense area has a baffle arranged in the left and right directions. The carbon bricks in the carbon frame are arranged obliquely and abut against the dense area. A dust collection chamber is formed between two adjacent carbon bricks and the front side wall of the carbon frame. The baffle is located at the bottom of the dust collection chamber, so that a dust collection chamber with an opening located in front of the carbon bricks is formed between the baffle, the dense area, and the carbon bricks;

[0009] A vibration device is installed in the box to shake off the adhered objects on the carbon bricks.

[0010] The effect is that the exhaust gas enters the air intake chamber through the air inlet and then enters the diversion channel. This diversion channel is specially used to guide the flow of gas. Under the guidance of the diversion channel, the gas passes through the carbon bricks in the carbon frame. These carbon bricks have extremely strong adsorption capacity and can effectively adsorb harmful substances in the exhaust gas. After purification by the carbon bricks, it will enter the air outlet chamber. In the air outlet chamber, the gas is finally discharged into the external environment through the air outlet. In order to ensure that the carbon bricks can continue to work efficiently, when too many impurities accumulate on the windward side of the carbon bricks, the vibration device will start and control the box to vibrate. This vibration can effectively strip off the impurities on the windward surface of the activated carbon bricks through the action of inertia, thereby avoiding the blockage problem of carbon bricks. The stripped impurities will fall into the dust collection chamber and then fall on the baffle. Under the guidance of the baffle, these impurities move backward along the top surface of the baffle and finally enter the dust collecting chamber, waiting for subsequent processing.

[0011] Preferably, the box body is provided with a discharge port and an outlet port connected to the branch channel, and baffles are clamped on the discharge port and the outlet port. The outlet port can discharge saturated carbon bricks by pulling out the carbon frame, and then insert the carbon frame for adding new carbon bricks through the discharge port.

[0012] Preferably, a slider is provided on the side of the charcoal frame, and a slide groove cooperating with the slider is provided on the inner side of the baffle. When the slider is located in the slide groove, the baffle is pulled outward to pull out the charcoal frame. When replacing the carbon bricks, the operation is simple and efficient, and the maintenance cost is low.

[0013] Preferably, the branch channel is located at one end of the air inlet cavity and is equipped with an adjustment component for adjusting the air intake volume. When the pressure at the front end of the branch channel is large, the adjustment component reduces the air intake area to prevent the air flow from passing through the carbon bricks quickly, resulting in the inability to fully adsorb the air flow.

[0014] Preferably, the adjustment component includes a vertical rod and a plurality of rotating plates arranged in an array along the vertical direction. Two rotating shafts are provided at the ends of the rotating plates, one of which is rotatably mounted with the box body, and the other is rotatably connected with the vertical rod. A driving component for controlling the movement of the vertical rod is installed in the diversion channel. When the pressure at the front end of the diversion channel is relatively high, the driving component will start and control the vertical rod to rotate. The purpose of this action is to reduce the air inlet area and prevent the airflow from passing through the carbon bricks at too fast a speed, so as to avoid the airflow from being unable to be fully adsorbed. By adjusting the angle of the rotating plate, the speed of the airflow can be reduced, thereby improving the adsorption effect of the carbon bricks.

[0015] Preferably, the driving assembly includes an abutment rod fixedly connected to a vertical rod away from the discharge port, one end of the abutment rod can abut against the front side of the charcoal frame, and an elastic member is connected between the abutment rod and the box body, which is used to apply an elastic force to the vertical rod toward the charcoal frame. When the pressure on the charcoal frame increases, the charcoal frame moves upward along the diversion channel, thereby rotating the rotating plate and reducing the air inlet area.

[0016] When the charcoal frame is pulled out from the discharge port, the abutment rod disengages from the charcoal frame, causing the rotating plate to rotate and close. After the charcoal frame is completely pulled out, the thrust applied by the remaining charcoal frame to the abutment rod is less than the pulling force of the elastic member on the charcoal frame, so that the rotating plate remains in a closed state. In the process of the charcoal frame at the front end of the branch channel being pulled out, the rotary wheel will also disengage from the charcoal frame. At this time, the vertical rod will move in the direction close to the branch channel under the elastic force of the spring. This action causes the rotating plates to overlap in sequence, effectively preventing the airflow from entering the branch channel. When the charcoal frame is completely pulled out, the other charcoal frames will begin to slide downward due to the action of gravity. These charcoal frames will continue to slide down until they are against the rotary wheel. Since the weight of one charcoal frame is reduced at this time, the total weight of the remaining charcoal frames is not enough to overcome the elastic force of the spring, so the abutment rod will not move. In this case, the rotating plates still remain in a state of overlapping with each other. However, when the charcoal frame with replaced charcoal bricks is put into the discharge port, the thrust received by the abutment rod will increase. This increased thrust causes the abutment rod to move away from the diverter channel, thereby driving the vertical rod to rotate. As the vertical rod rotates, the rotating plates also rotate, allowing the airflow to pass through the gaps between the rotating plates and smoothly enter the diverter channel.

[0017] Preferably, the elastic member is a spring.

[0018] Preferably, the charcoal frame consists of a frame body and a movable plate, the movable plate is hinged at the bottom of the frame body, and a fastener is installed between the movable plate and the frame body, the fastener is used to fix the movable plate to ensure that the charcoal frame remains stable during transportation and installation. At the same time, the design of the movable plate allows it to be easily opened when the carbon bricks need to be replaced, simplifying the maintenance process.

[0019] Preferably, when placing the carbon bricks, the front side of the charcoal frame is placed flat, and the carbon bricks are placed side by side against the baffle. After placement, the movable plate is rotated so that it rotates against the carbon bricks, and finally the fasteners fix the movable plate and the frame together. This arrangement makes it easy to place the carbon bricks into the charcoal frame while ensuring that the carbon bricks are tightly arranged.

[0020] By adopting the above technical solution, the beneficial effects of the present invention are:

[0021] 1. When excessive impurities accumulate on the windward side of the activated carbon bricks, the vibration device will start, and by controlling the vibration of the box, the impurities on the windward surface of the activated carbon bricks will be peeled off by inertia to prevent blockage. Then, the impurities will fall into the dust collection chamber and move backward along the top of the baffle under the guidance of the baffle bar, and finally enter the dust collection chamber to prevent the impurities from being blown up again;

[0022] 2. If there is a high pressure condition at the entrance of a specific branch channel, the airflow thrust on the carbon frame will increase. This phenomenon will cause the thrust on the abutment rod to decrease, causing the spring to contract. Subsequently, the vertical rod drives the rotating plates to rotate in the opposite direction, which reduces the gap between the rotating plates. This effectively reduces the airflow speed and maintains the adsorption effect of the carbon bricks. This design mechanism ensures a more uniform distribution of airflow in each branch channel.

[0023] 3. When the charcoal frame is pulled out by the operator, the connection between the rotor and the charcoal frame will be separated. During this separation process, the vertical rod is affected by the spring force and begins to move in the direction of the diversion channel. As the vertical rod moves, the rotating plates will overlap in sequence. This series of actions effectively prevents the entry of external airflow. When the charcoal frame is completely pulled out, the remaining charcoal frame cannot provide enough force to overcome the elastic force of the spring, so the abutment rod will remain in place. The operator can replace the charcoal bricks without stopping the equipment, thereby greatly improving production efficiency. At the same time, this design also avoids the leakage of untreated exhaust gas during the replacement of carbon bricks, ensuring the environmental protection and safety of the production process.

[0033] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0034] like Figure 1-Figure 7 As shown, an exhaust gas treatment device for chemical equipment includes a box body 1, a filter component 2 and a vibration device (not shown in the figure). The filter component 2 is installed in the box body 1, dividing the interior of the box body 1 into an air inlet chamber 14 and an air outlet chamber 15. The top and bottom ends of the box body 1 are respectively provided with an air outlet and an air inlet. The air inlet chamber 14 is connected to the air inlet, and the air outlet chamber 15 is connected to the air outlet. The vibration device is installed in the box body 1. When too many impurities accumulate on the windward surface of the carbon bricks, the vibration device controls the vibration of the box body 1, thereby stripping off the impurities on the windward surface of the activated carbon bricks through inertial force, avoiding blockage and improving adsorption efficiency.

[0035] The filter assembly 2 includes a mounting frame 21, multiple groups of carbon frames 22 and an adjustment assembly 23. The mounting frame 21 is in an inverted shape, so that the air outlet cavity 15 is surrounded by the front, rear and top sides of the air inlet cavity 14. A plurality of inclined diversion channels are provided on the mounting frame 21. The diversion channels are divided into two groups, and the two groups of diversion channels are symmetrically arranged. The diversion channels in each group of diversion channels are evenly distributed in the vertical direction. The front end of the diversion channel is connected to the air inlet cavity 14, and the rear end is connected to the air outlet cavity 15. The height of the front end of the diversion channel is less than the height of the rear end. The carbon frame 22 is located between the diversion channels, so that under the action of gravity, the carbon frame 22 slides along the diversion channel toward the air inlet cavity 14. The adjustment assembly 23 is located at the front end of the diversion channel for adjusting the air intake volume.

[0036] The charcoal frame 22 includes a frame body 221, a movable plate 222 and a fastener 228. The movable plate 222 is hinged at the bottom of the frame body 221. The charcoal frame 22 is adapted to the diverter channel. Therefore, the upper and lower side surfaces of the charcoal frame 22 are in contact with the upper and lower walls of the diverter channel, so that the charcoal frame 22 remains stable during the sliding process. The movable plate 222 can be rotated when replacing the activated carbon bricks in the charcoal frame 22, which is convenient for replacing the carbon bricks. The fastener 228 then fixes the movable plate 222 to ensure that the carbon bricks fit tightly. The rear side of the frame body 221 is open, and a plurality of hollow areas 223 are arranged in an upper and lower array on the front side. The other areas on the front side are dense Solid area 224, air flow cannot pass through dense area 224, and a baffle 225 arranged in the left and right directions is fixedly connected to the dense area 224 between two adjacent hollow areas 223. The top surface of the baffle 225 gradually tilts downward from the front to the rear. Since the carbon bricks in the carbon frame 22 are in an inclined state, one side of the carbon bricks is against the front inner wall of the frame 221, and the abutting position is located in the dense area 224 and below the adjacent baffles. Therefore, a dust collection chamber 226 is formed between the two adjacent carbon bricks and the front side wall of the carbon frame 22, and a dust collecting chamber 227 (such as the dust collecting chamber 227) with an opening located on the front side of the carbon bricks is surrounded by the baffle 225, the dense area 224, and the carbon bricks. Figure 7 As shown in FIG. 2 ), when the airflow passes through the carbon bricks, impurities in the airflow hit the surface of the carbon bricks. Some of the impurities are absorbed by the carbon bricks, while the rest fall into the dust collection chamber 226 due to inertia, then fall on the baffle 225, move backward along the top surface of the baffle 225, and finally enter the dust collection chamber 227, preventing the airflow from blowing up the impurities again.

[0037] When placing the carbon bricks, place the front side of the carbon frame 22 flat on a horizontal surface, and place the carbon bricks side by side against the baffle 225. After placement, rotate the movable plate 222 so that it rotates against the carbon bricks, so that all the carbon bricks fall over, and finally the fastener 228 fixes the movable plate 222 and the frame 221 together.

[0038] A discharge port 11 and an outlet port 12 connected to the branch channel are provided on the box body 1, and a baffle 13 is provided on the discharge port 11 and the outlet port 12. The baffle 13 is connected to the discharge port 11 or the outlet 12 by a snap connection, so that the baffle 13 can be removed from the discharge port 11 or the outlet 12. A slider is provided on the side of the frame body 221, and a slide groove that cooperates with the slider is provided on the inner side of the baffle 13. When the carbon bricks in the branch channel need to be replaced, the baffle 13 on the outlet port 12 is pulled outward to pull out the carbon frame 22 located at the front end of the branch channel, and then the remaining carbon frames 22 slide downward by a distance of one carbon frame 22, so that the carbon frame 22 of the discharge port 11 moves downward to make way for the next carbon frame 22 entering.

[0039] The adjusting assembly 23 includes two fixed rods 231, two vertical rods 232, multiple rotating plates 233 and a driving assembly. The multiple rotating plates 233 are arranged in an array along the vertical direction. Both ends of the rotating plate 233 are fixedly connected to two rotating shafts. The rotating plate 233 is L-shaped. One of the two rotating shafts on the end face is located at the top of the L-shaped surface, and the other is located in the middle. The rotating shafts at the top of the L-shaped surface at both ends of the rotating plate 233 are respectively hinged on the two fixed rods 231. The fixed rod 231 is fixedly installed in the box body 1, and the other rotating shaft in the middle is hinged to the vertical rod 232. The driving assembly is installed at the front end of the diversion channel for controlling the vertical rod 232 to move away from or close to the diversion channel, thereby controlling the rotation of the rotating plate 233. When the pressure at the front end of the diversion channel is large, the driving assembly controls the vertical rod 232 to rotate, thereby reducing the air inlet area to avoid the airflow passing through the carbon bricks quickly, resulting in the inability to fully adsorb the airflow. After the angle of the rotating plate 233 is adjusted, the airflow speed is slowed down and the adsorption effect of the carbon bricks is improved.

[0040] The drive assembly includes an abutment rod 234 and an elastic member 235, one end of the abutment rod 234 is fixedly connected to the vertical rod 232 away from the discharge port 12, and the other end of the abutment rod 234 is rotatably installed with a runner 2341. The elastic member 235 is a spring, and the two ends of the spring are respectively connected to the box body 1 and the abutment rod 234, thereby applying an elastic force toward the direction of the branch channel to the abutment rod 234, so that the runner 2341 can be abutted against the frame body 221. When the carbon frame 22 at the front end of the branch channel is pulled out, the runner 2341 is separated from the carbon frame 22, and the vertical rod 232 moves in the direction close to the branch channel under the elastic force of the spring, thereby causing the rotating plate 233 to overlap in sequence, preventing air from entering the branch channel. When the carbon frame 22 is completely pulled out, the remaining carbon frames 22 slide downward under the action of gravity until the carbon frame 22 abuts against the runner 2341. Due to the reduction of one carbon frame 22 Weight, at this time, the remaining charcoal frame 22 is not enough to overcome the elastic force of the spring to move the abutment rod 234. Therefore, at this time, the rotating plates 233 are still in a mutually overlapping state. After the charcoal frame 22 with replaced carbon bricks is put into the discharge port 11, the thrust received by the abutment rod 234 increases, thereby causing the abutment rod 234 to move in the direction away from the branch channel, causing the vertical rod 232 to drive the rotating plate 233 to rotate, so that the airflow can enter the branch channel through the gap between the rotating plates 233. When the pressure at the front end of the branch channel is large, the airflow thrust received by the charcoal frame 22 increases, thereby reducing the thrust on the abutment rod 234, and the spring contracts, causing the vertical rod 232 to drive the rotating plate 233 to rotate in the opposite direction, thereby reducing the gap between the rotating plates 233, slowing down the airflow speed, and maintaining the carbon brick adsorption effect. This design ensures the uniform distribution of airflow among all branch channels, thereby improving the overall purification efficiency.

[0041] In order to balance the supporting force on the carbon frame 22, an auxiliary support assembly 24 is provided at one end of the front end of the branch channel near the discharge port 12. The auxiliary support assembly 24 includes a support rod 241 and a tension spring 242 arranged along the length direction of the branch channel. The support rod 241 is slidably mounted on the inner wall of the branch channel, and the support rod 241 is provided with an abutment portion that can abut against the front side of the carbon frame 22. The tension spring 242 is connected between the support rod 241 and the box body 1. When the support rod 241 and the abutment rod 234 are not abutting against the carbon frame 22, the two are used to support the plane of the carbon frame 22. The spring and the tension spring 242 are located on the same plane, and have the same elastic coefficient and the same initial elastic force, ensuring that the forces at both ends of the carbon frame 22 are balanced, thereby preventing the carbon frame 22 from tilting or getting stuck. Because the auxiliary support assembly 24 is provided, the elastic coefficient of the spring should be adjusted smaller than the elastic coefficient of the spring when the auxiliary support assembly 24 is not provided, so as to ensure that when the weight of one carbon frame 22 is reduced, the remaining carbon frame 22 is insufficient to overcome the elastic force of the spring to move the abutment rod 234, ensuring that the rotating plates 233 are still in a mutually overlapping state (such as Figure 5As shown), when the carbon frame 22 with replaced carbon bricks is put in, the thrust on the abutment rod 234 increases, causing the spring and the tension spring 242 to deform, thereby causing the abutment rod 234 to move away from the diversion channel, causing the vertical rod 232 to drive the rotating plate 233 to rotate (as shown). Figure 4 shown).

[0042] Working principle:

[0043] During the exhaust gas treatment process, the exhaust gas enters the air inlet chamber 14 through the air inlet, then enters the branch channel through the gap between the rotating plates 233, and then passes through the carbon bricks in the carbon frame 22. The carbon bricks adsorb harmful substances in the exhaust gas, and the purified gas enters the air outlet chamber 15 and is finally discharged through the air outlet. When too many impurities accumulate on the windward side of the carbon bricks, the vibration device controls the vibration of the box body 1, thereby stripping the impurities on the windward surface of the activated carbon bricks through inertial force to avoid blockage. The impurities fall into the dust collection chamber 226, then fall on the baffle 225, move backward along the top surface of the baffle 225, and finally enter the dust collection chamber 227;

[0044] When the pressure at the front end of a certain branch channel is high, the airflow thrust on the carbon frame 22 increases, thereby reducing the thrust on the abutment rod 234. The spring contracts, causing the vertical rod 232 to drive the rotating plate 233 to rotate in the opposite direction, thereby reducing the gap between the rotating plates 233, slowing down the airflow speed, and maintaining the carbon brick adsorption effect. This design can make the airflow more evenly distributed among all the branch channels.

[0045] When the carbon frame 22 at the front end of the branch channel is pulled out, the runner 2341 is separated from the carbon frame 22. Under the elastic force of the spring, the vertical rod 232 moves toward the direction close to the branch channel, so that the rotating plates 233 overlap in sequence to prevent the airflow from entering the branch channel. When the carbon frame 22 is completely pulled out, the remaining carbon frames 22 slide downward under the action of gravity until the carbon frame 22 and the runner 2341 are against each other. Since the weight of one carbon frame 22 is reduced, the remaining carbon frames 22 are not enough to overcome the spring. The elastic force causes the abutment rod 234 to move, so the rotating plates 233 are still in a mutually overlapping state at this time. When the carbon frame 22 with replaced carbon bricks is put into the discharge port 11, the thrust exerted on the abutment rod 234 increases, causing the abutment rod 234 to move away from the diversion channel, so that the vertical rod 232 drives the rotating plate 233 to rotate, so that the air flow can enter the diversion channel through the gap between the rotating plates 233. This design allows the carbon bricks to be replaced without stopping the machine, avoiding the overflow of untreated exhaust gas during replacement.

[0046] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
