Description

Technical Field

[0001] The invention belongs to the field of waste gas treatment technology or equipment, and in particular relates to an integrated reducible activated carbon filter cartridge waste gas treatment device. Background Art

[0002] In the field of activated carbon waste gas treatment technology, in order to remove various pollutants such as toxic substances contained in the waste gas, various media are needed to perform filtration treatments such as adsorption and elimination. The general structure is to install the filter media in sequence inside the activated carbon waste gas treatment device, so that the waste gas passes through multiple layers of filter media in sequence. After a period of use, harmful substances will be adsorbed and accumulated on the filter media. Therefore, it is necessary to maintain and clean the media in time to make it work again. The commonly used solution is to remove the filter media for cleaning, maintenance or replacement, but this solution is time-consuming and labor-intensive, and is not conducive to improving the efficiency of activated carbon waste gas treatment. Another option is to introduce catalytic reducing gas into the filter chamber and use the catalytic reducing gas to treat the medium. This treatment method does not require disassembly and replacement of the filter medium, and has a small workload and high efficiency. However, the use of the filter device needs to be suspended during this treatment process. In some cases, such as when the concentration of gas pollutants is high, the filter medium near the air inlet may quickly reach the adsorption limit and need to be cleaned and maintained, while the subsequent filter medium still has a high adsorption capacity. However, in order to ensure the effectiveness of the entire adsorption device, the entire equipment still needs to be suspended for cleaning and maintenance. This process leads to a waste of adsorption resources, reduces the overall performance of the adsorption device, and increases the frequency of cleaning and maintenance. Especially in the process of large-scale or high-frequency activated carbon waste gas treatment projects, it will greatly affect the efficiency of the entire waste gas treatment.

[0003] On the other hand, the existing exhaust gas treatment equipment needs to be equipped with various functional pipes including air inlet pipe, air outlet pipe and catalytic pipe, which means that in addition to the cabinet or tower structure, many pipes need to be connected during the equipment installation process, such as Figure 5As shown, at least the main air inlet pipe 7a, the main air outlet pipe 7b, the branch pipe 7e and the catalytic air inlet pipe 7c, the catalytic air inlet pipe outlet pipe 7d, and the catalytic pipe branch pipe 7f are included. Each pipe needs to be independently connected to each box through a branch pipe. The interlaced arrangement of each pipe is dazzling. The installation design and maintenance of each pipe lead to a high installation and use cost of the exhaust gas treatment equipment. At the same time, corresponding solenoid valves need to be configured between various pipes and the filter box or filter chamber to control the opening and closing of each pipe. Even the simplest catalytic reduction task requires at least 3 to 6 valves to be controlled and operated respectively. When the volume of the catalytic equipment expands and the processing area becomes more and larger, the corresponding valves will also increase rapidly, resulting in a sharp increase in the control program and the required valve action amount when the entire equipment is used. On the one hand, the operation is more difficult, and the requirements for the operator and the operating system are higher. At the same time, the probability of problems is immediately increased, and the stability and effectiveness of the exhaust gas treatment device are greatly reduced, which is not conducive to the continuous and stable progress of the treatment program.

[0021] Compared with the traditional exhaust gas treatment device, the beneficial effects of the present invention are:

[0022] 1. It reduces to the greatest extent the various types of air inlet and outlet pipes that originally needed to be separately configured, processed and installed, especially the branch pipes connecting the main air inlet and outlet with each filter area, reduces most of the valves, makes full use of the characteristics of the shell structure, and uses the shell of each chamber and the external shell to enclose each channel.

[0023] 2. Based on the reduction of pipelines, structural integration, and the internal overall control conversion structure, the amount of valves used is reduced by 2 / 3 compared with traditional exhaust gas treatment devices. Only one solenoid valve is needed to complete the process from air intake and outlet to catalytic reduction in a filtration area, which greatly saves the operating process, simplifies the control conversion system, and also greatly reduces the cost of solenoid valves, power supply and control lines.

[0024] 3. The exhaust gas inlet and outlet ducts and catalytic reduction ducts of the device form a whole with the filter chamber, which reduces redundant ducts and connecting pipes, reduces the air leakage rate of the equipment, and has a small size and compact structure, which effectively improves the efficiency of equipment manufacturing and construction.

The maintenance and cleaning of the filter chamber are also simpler, saving 80% of the operating hours, solving the problems of multiple layers of block activated carbon stacking, which leads to the easy powdering and crushing of the bottom layer of active carbon, gas channel blockage, and secondary head formation. It avoids the problems of multiple layers of block activated carbon stacking, blocked activated carbon pores, and excessive resistance, thereby improving the efficiency of waste gas treatment and reducing labor and resource consumption.

[0026] 5. The present invention can realize synchronous control of a group of diversion chambers and filter chambers connected to the control rod. Each group controlled by different control rods is independently controlled. Each group performs activated carbon waste gas treatment or catalytic maintenance procedures separately or simultaneously. They are isolated from each other and will not interfere with each other. They can be flexibly adjusted according to needs, and the switching operation of the whole process is simple, efficient and low-cost, and can conveniently realize automated processing. At the same time, the structure of the present invention is simple and the principle is concise and easy to understand. It can be flexibly adjusted and set according to the needs of catalytic treatment and actual financial capabilities, and can be flexibly configured in various waste gas treatment scenarios to achieve the best cost-effectiveness.

[0027] 6. Based on the integrated and compact structure equipment, the path length of the exhaust gas in and out of the filter chamber is greatly reduced, and there is no need to pass through a long pipeline. On the one hand, it effectively improves the exhaust gas treatment efficiency and compresses the exhaust gas retention area. On the other hand, it greatly reduces the workload of cleaning and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The technical solution of the present invention is described in detail below with preferred implementation modes.

[0037] like Figure 1 , Figure 2 , Figure 3 As shown, the shell 1 is surrounded by a closed shell plate, and a guide plate 1a is arranged on the upper inner side of the shell. The guide plate 1a and the inner wall and top of the shell form a guide chamber A, and the guide chamber A is provided with a pipe or hole 9a connected to the exhaust gas source or the pre-filter purification equipment; in order to further compress the equipment volume and realize intensive processing, the guide chamber A can be directly connected to the outlet of the pre-filter equipment through the pipe or hole 9a to realize structural integration.

[0038] Two rows of guide holes 1b are provided on the guide plate 1a, and the number of guide holes in each row is set according to actual needs. In this embodiment, there are six guide holes in total, 3×2. The lower part of the guide holes 1b is surrounded by the shell plate to form a diverter chamber B and a filter chamber C in sequence. At the same time, corresponding to the two rows of guide holes, the diverter chamber B and the filter chamber C are divided into two parts, and a catalytic channel area is provided in the middle of the two parts. The diverter chamber and the filter chamber corresponding to the two rows of guide holes are respectively arranged on both sides of the catalytic channel area; the catalytic air inlet channel 3a and the catalytic air outlet channel 3b are provided in the catalytic channel area, the catalytic air inlet channel 3a is arranged near the filter chamber C, and the catalytic air outlet channel 3b is arranged near the diverter chamber B; the catalytic air inlet channel 3a and the catalytic air outlet channel 3b are respectively connected to the external catalytic reduction device.

[0039] According to actual needs, 3a can also be used as an outlet channel, and similarly 3b can be used as an inlet channel, and the catalytic airflow flows in the opposite direction of the aforementioned direction.

[0040] Furthermore, a partition can be installed in the middle of the catalytic channel along the airflow direction to divide the flow guide chamber A into two parts. The partition is used to bear the top of the shell on the one hand, and to guide the flow on the other hand. At the same time, the air inlet 9a is divided into two air inlets, which are respectively connected to the two parts of the flow guide chamber.

[0041] The diversion chamber B is connected with the diversion chamber A through the diversion hole 1b; in the specific implementation, each diversion hole 1b is opposite to and connected with at least one diversion chamber B; each diversion chamber B and the filter chamber C are surrounded by a shell plate, and a filter cartridge mounting hole 1c is provided on the shell plate between the filter chamber C and the diversion chamber B, and an air outlet hole 9b is provided at the bottom of each filter chamber C, and the air outlet holes 9b are gathered into an air outlet channel and connected to the air outlet fan, and the diversion holes 1b corresponding to the upper and lower positions are respectively coaxial with the air outlet holes 9b.

[0042] An air guide cylinder is installed on the inner wall of each flow diversion chamber B and filter chamber C, and the air guide cylinders 4a and 4b in the corresponding flow diversion chamber B and filter chamber C are installed in correspondence with each other. The air guide cylinder is fixed on the inner wall of each chamber facing the catalytic channel area. The air guide cylinder is hollow. The hollow part of the air guide cylinder in the flow diversion chamber B is connected to the catalytic outlet channel 3b, and the hollow part of the air guide cylinder in the filter chamber C is connected to the catalytic inlet channel 3a. The downward end surface of the air guide cylinder is respectively provided with openings.

[0043] like Figure 1 , Figure 4 As shown, the activated carbon waste gas treatment assembly includes a filter cartridge 5a, a solenoid valve 5b, a control rod 5c, and an upper end cover 5d, a middle end cover 5e, and a lower end cover 5f sleeved on the control rod; wherein:

[0044] One end of the filter cartridge 5a is installed in the filter chamber C through the filter cartridge mounting hole 1c. The number of the control rods 5c is the same as the number of the guide holes 1b, and each control rod is respectively inserted into a group of corresponding flow chambers B and filter chambers C, and is coaxially aligned with the corresponding guide holes 1b and air outlet holes 9b and the openings 4c and 4d on the two air guides. At the same time, a through hole 9c is also correspondingly provided on the shell plate provided with the filter cartridge mounting hole. The number of the solenoid valves is the same as the number of the control rods, and one end of each solenoid valve is connected to the control rod and the other end is fixed to the shell, so that the solenoid valve can drive the control rod to move up and down during the switching process.

[0045] On each corresponding control rod, the upper end cover 5d is arranged above the corresponding guide hole, the middle end cover 5e is arranged in the corresponding diversion chamber B and is located below the opening 4d on the air guide cylinder in the diversion chamber B, and the lower end cover 5f is arranged in the corresponding filter chamber C and is located below the opening 4c on the air guide cylinder in the filter chamber C.

[0046] Inside each filter chamber, the installation position of each end cover meets the following requirements:

[0047] In the catalytic reduction process: when the solenoid valve drives the control rod to move downward, the upper end cover 5d closes the upper guide hole 1b, the middle end cover 5e opens the opening 4d on the upper air guide cylinder, and the lower end cover 5f opens the opening 4c on the lower air guide cylinder and closes the lower air outlet hole 9b;

[0048] During the exhaust gas treatment process: when the solenoid valve drives the control rod to move upward, the upper end cover 5d opens the guide hole 1b, the middle end cover 5e closes the opening 4d on the upper air guide cylinder, and the lower end cover 5f opens the lower air outlet hole 1b and closes the opening 4c on the lower air guide cylinder.

[0049] A preferred method is to install multiple filter cartridges 5a in an array in the filter chamber C to improve the filtering effect of the filter chamber. At the same time, the apertures of the corresponding guide holes 1a and 9b are increased, and the end covers 5d, 5e and 5f are enlarged accordingly.

[0050] Preferably, a cylindrical filter cartridge is used, and the surface of the filter cartridge is configured to be pleated. The cylindrical and pleated structure greatly increases the total area of ​​the filter surface and improves the filtering and catalytic reduction capabilities.

[0051] Based on the above structure, the present invention can realize synchronous control of at least one group of diversion chambers B and filter chambers C connected to the control rod, and each group controlled by different control rods is independently controlled. At the same time, each group can perform activated carbon exhaust gas treatment or catalytic maintenance procedures separately or simultaneously, and can be flexibly adjusted according to needs. The specific implementation steps are as follows:

[0052] When activated carbon waste gas treatment is required, one or more solenoid valves are controlled to drive the operating rod to move upward as needed, and the guide chamber A is connected to the corresponding guide chamber B through the guide hole 1b. At this time, the upper and lower air guide tube openings are closed, and the waste gas entering the guide chamber A from the waste gas inlet pipe can only enter the filter cartridge for treatment, and then reach the exhaust fan from the outlet hole 9b to be discharged, completing the activated carbon waste gas treatment procedure.

[0053] When the activated carbon waste gas treatment is completed or the amount of activated carbon waste gas treatment required increases or decreases, the number of filter chambers C in operation can be controlled by opening or closing the solenoid valve, so as to better control the cost and efficiency of activated carbon waste gas treatment;

[0054] When the filter cartridge in a filter chamber C is completely saturated during the activated carbon waste gas treatment process and catalytic reduction is required, the corresponding control lever is driven downward to close the guide hole connected to the guide chamber, and at the same time, the openings on the two air guides are opened to connect the catalytic chamber with the air inlet and outlet of the catalytic channel, so that the catalytic gas output by the catalytic reduction equipment can enter the filter chamber for catalytic reduction, thereby restoring the function of the catalytic chamber.

[0055] In addition to the above structure and principle, according to the actual application and design requirements, the operating lever can also be moved downward to close the activated carbon exhaust gas treatment program and open the catalytic reduction program.

[0056] Furthermore, the activated carbon waste gas treatment device can be simplified, and the filter cartridge can be placed horizontally, thereby eliminating a guide chamber and allowing the airflow to flow directly in and out.

[0057] Based on the above structure, the device can realize flexible waste gas treatment and catalytic reduction process. All filter chambers can be used for activated carbon waste gas treatment; or a single filter chamber C can be used for catalytic reduction, and one or more other filter chambers C can be used for activated carbon waste gas treatment. The switching operation of the entire process is simple, efficient, and low-cost, and can easily realize automated processing. At the same time, the structure of the present invention is simple and the principle is easy to understand. It can be flexibly adjusted and set according to the air volume requirements of catalytic treatment and actual financial capabilities, and can be flexibly configured in various waste gas treatment scenarios to achieve the best cost-effectiveness.

[0058] Based on actual use and operation summary, the present invention also includes the following improvements to the above-mentioned connection structure:

[0059] It is preferred to adopt the symmetrical structural arrangement shown in the figures of this embodiment to realize the intensive and simple volume of the equipment, including arranging the flow guide chambers and the catalyst chambers in an array on both sides of the catalyst channel; the air guide cylinders inside the flow guide chambers and the catalyst chambers are kept at the same height, so that the air guide cylinders located at the top are connected to the catalyst outlet channel at the same time, and the air guide cylinders located at the bottom are connected to the catalyst inlet channel at the same time;

[0060] During the catalytic reduction process, since high-temperature treatment is required, in order to improve energy utilization efficiency and reduce power consumption, insulation cotton is respectively arranged on the outside of the catalytic air inlet channel and the catalytic air outlet channel, as well as on the outside of the diversion chamber and the filter chamber, and even the inner wall of the shell is completely covered with insulation cotton to ensure the temperature of the catalytic reduction gas.

[0061] In order to prevent the filter cartridge from generating fire hazards due to local high temperature during the catalytic reduction process, a fire-fighting component is arranged inside the diversion chamber or the filter chamber. The fire-fighting component includes a water spray pipe 9f and a control device. The water spray pipe is provided with water spray ports facing the inside or outside of the filter cartridge. The control device is used to control the opening or closing of the water spray ports as needed. The control device can be an existing alarm device, a monitoring device, a temperature control device, etc. Its basic purpose is to perform corresponding actions according to fire manifestations such as ambient temperature or smoke.

[0062] In another embodiment, the fire fighting assembly may also be a nitrogen fire fighting assembly.

[0063] It should be pointed out that the above embodiments are only described in a preferred manner and the core main structure thereof, and some conventional and basic structures are not described in detail, but can be reasonably inferred according to the purpose and main mechanism of the present invention, including that there must be pipes or holes on the shell for connecting each channel or hole with an external device, such as a port 9i or a pipe for connecting the air outlet hole 9b with an external air outlet fan, an air outlet fan 9h or a catalytic reduction device separately arranged with the shell or integrally connected with the shell, an auxiliary ventilation port 9g for flushing in dilution gas or other gas, and a window 9j for observing the internal state of the device, etc.

[0064] In particular, according to actual needs, hole 9a can also be used as an outlet channel to connect to subsequent equipment or a fan; 9i can be used as an inlet channel to connect to the previous equipment or an exhaust gas source. Due to the particularity of the inlet and outlet gases, the outlet channel and the inlet channel can also be on the same facade as needed.

[0065] Based on the above structure and procedure, it can also be simplified according to actual needs. When the catalytic reduction process is not required, only the air inlet channel 9a, the guide chamber A, the guide plate, the filter cartridge 5a, the filter chamber C and the air outlet 9i in the above structure can be retained. The simplified device process is: the exhaust gas enters the guide chamber A from 9a, passes through the activated carbon filter cartridge, and is discharged by the air outlet fan after being treated by the activated carbon filter cartridge. Furthermore, multiple simplified devices can be connected in parallel to achieve a modular structure to meet the needs of various working conditions.

[0066] In particular, in the activated carbon waste gas treatment device, the filter cartridge can be placed horizontally, and the guide chamber is eliminated, and the airflow adopts a straight-in and straight-out method.

[0067] The shell structure is arranged in a cubic form in this embodiment, but it can also be arranged in a cylindrical or special-shaped structure to meet the needs of different installation or use environments.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
