Description

Technical Field

[0001] The present invention relates to the technical field of tail gas treatment systems, and particularly to a drying tail gas treatment system and method containing ammonium sulfate. Background Art

[0002] The drying tail gas containing ammonium sulfate mainly comes from the production process of ammonium sulfate, especially in the drying stage of ammonium sulfate. These tail gases contain ammonium sulfate particles, water vapor, possibly unreacted ammonia, sulfur dioxide, and other gaseous pollutants. Therefore, a corresponding tail gas treatment system is required to treat the drying tail gas containing ammonium sulfate to avoid the impact of the above gaseous pollutants on the external environment.

[0003] When processing, it is necessary to first perform pre-dust removal treatment on the tail gas to remove some impurities in the tail gas, thereby improving the efficiency of subsequent tail gas treatment. The pre-dust removal treatment usually can adopt cyclone dust removal or bag dust removal processes, and then the treated tail gas is introduced into the absorption tower for washing to remove various gaseous pollutants in the tail gas.

[0004] When the existing tail gas treatment system washes the tail gas after the pre-dust treatment is completed, incompletely treated tail gas is usually generated, and these incompletely treated tail gases need to be re-treated through a corresponding circulation system. Most of the existing treatment systems directly introduce these incompletely treated tail gases into the intake port to be mixed with the newly entering tail gas for secondary treatment. However, since the incompletely treated tail gas has undergone the primary washing itself, it does not need to completely repeat the entire process of the primary washing, thus unnecessarily increasing the processing burden of the entire system and resulting in a low overall processing efficiency of the system. Summary of the Invention

[0005] The purpose of the present invention is to provide a drying tail gas treatment system and method containing ammonium sulfate, which can divide the entire treatment system into small treatment units, and then monitor the treatment quality of each treatment unit, so as to better selectively introduce the incompletely treated tail gas, thereby reducing the overall processing burden of the system and improving the overall processing efficiency of the system.

[0006] To achieve the above purpose, the present invention provides a drying tail gas treatment system and method containing ammonium sulfate, including a treatment tank and a moving seat. The moving seat is installed at the bottom of the treatment tank, and a working component is also included.

[0007] The working components include an access channel, an export channel, a gas monitor, a joint component, and a distribution component. The access channel and the export channel are respectively arranged on the front and rear sides of each treatment box. Two adjacent treatment boxes are connected by bolts, connecting the set export channel on the front treatment box to the access channel on the rear treatment box. The gas monitor is installed on each access channel. The joint component is used for the introduction of tail gas and the emission of tail gas after treatment is completed. The distribution component is used to distribute and guide the incompletely treated waste gas according to the actual gas monitoring situation.

[0008] Among them, the joint component includes an introduction frame and a discharge frame. The introduction frame is connected to the access channel of the treatment box on the foremost side, and is used to introduce the generated waste gas into the treatment box on the foremost side. The discharge frame is connected to the export channel of the treatment box on the rearmost side, and is used to export the waste gas after treatment is completed. The gas monitor is also arranged on the discharge frame.

[0009] Among them, the distribution component includes a selection control valve, a transition box, a guiding air pump, a reflux component, and an intake component. The selection control valve is installed at the gas outlet end of the discharge frame. The transition box is connected to the selection control valve, and the gas monitor is installed on the transition box. The guiding air pump is connected to the transition box. The reflux component is connected to the guiding air pump and is used to distribute and guide the incompletely treated waste gas. The intake component is connected to the transition box and is used to introduce external gas to empty the excess incompletely treated waste gas inside.

[0010] Among them, the reflux component includes a connecting row frame, a one-way control valve, and a connecting pipe. The connecting row frame is connected to the guiding air pump. The one-way control valve is installed on each treatment box. The one-way control valve is connected to the connecting row frame through the connecting pipe.

[0011] Among them, the intake component includes a fixed bracket, a movable plug block, and a support spring. The fixed bracket is fixedly installed inside the transition box. The movable plug block is slidably installed on the fixed bracket. The two sides of the support spring are respectively connected to the fixed bracket and the movable plug block.

[0012] Among them, the working components further include a partition board, a dividing baffle, a spraying component, and a liquid discharging component. Two partition boards are fixedly installed inside each treatment box. A plurality of dividing baffles are arranged between the two partition boards. The spraying component is installed on each treatment box and is used to wash the waste gas introduced inside. The liquid discharging component is arranged at the bottom of each treatment box and is used to discharge the accumulated cleaning liquid.

[0013] Among them, the spraying member includes a spraying row support, a conduit support, and a spraying pump. Two spraying row supports are provided inside each treatment tank. One spraying row support is arranged at the inner top of the treatment tank, and the other spraying row support is arranged at the bottom of the partition board. The conduit support is connected to the two spraying row supports and installed on the top of the treatment tank. The spraying pump is connected to the conduit support and installed on the top of the treatment tank.

[0014] Among them, the liquid discharging member includes a partitioned collection frame, a sliding baffle, a floating block, and a discharging frame. The partitioned collection frame is installed at the bottom of the treatment tank. Two independent storage areas are provided inside the partitioned collection frame. The two sliding baffles are respectively slidably installed in the corresponding two storage areas of the partitioned collection frame. Each sliding baffle is fixedly installed with the floating block. The discharging frame is connected to the partitioned collection frame.

[0015] A drying tail gas treatment system and method containing ammonium sulfate according to the present invention form a treatment system composed of a plurality of treatment tanks through the splicing and cooperation of the access channels and the export channels provided in the plurality of treatment tanks. The waste gas is introduced through the access channel of the treatment tank arranged at the frontmost side through the joint member, and then exported from the export channel of the treatment tank at the rearmost side. Then, the gas quality data in each treatment tank is collected through the gas monitor arranged on each access channel. Whether the emission requirements are met is judged by detecting the quality of the finally treated gas. When the emission requirements are met, the gas can be directly discharged, and when the requirements are not met, the quality data of the finally treated gas can be analyzed through the distribution member, so as to introduce the incompletely treated gas into a suitable treatment tank for secondary treatment.

Detailed implementation manners

[0026] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0027] In the description of the present invention, it should be understood that the meaning of "a plurality of" is two or more unless otherwise specifically defined.

[0028] Please refer to Figures 1 to 7, the present invention provides a drying tail gas treatment system and method containing ammonium sulfate: including a treatment tank 101, a moving seat 102 and a working component. The working component includes an access channel 103, an export channel 104, a gas monitor 105, a joint component and a distribution component. The joint component includes an introduction frame 106 and a discharge frame 107. The distribution component includes a selection control valve 201, a transition tank 202, a guiding air pump 203, a reflux component and an intake component. The reflux component includes a connecting row frame 204, a one-way control valve 205 and a connecting pipe 206. The intake component includes a fixed bracket 207, a movable plug 208 and a support spring 209. Through the foregoing solution, it solves the problem that most of the existing treatment systems directly introduce these incompletely treated tail gases into the intake port so as to mix them with the re-entering tail gases for secondary treatment. However, since the incompletely treated tail gases have undergone primary washing, they do not need to completely repeat the entire process of primary washing, thus unnecessarily increasing the treatment burden of the entire system and resulting in a relatively low overall treatment efficiency of the system.

[0029] Further, the moving seat 102 is installed at the bottom of the treatment tank 101. The access channel 103 and the export channel 104 are respectively arranged on the front and rear sides of each treatment tank 101. Two adjacent treatment tanks 101 are connected by bolts to connect the set export channel 104 on the front treatment tank 101 to the access channel 103 arranged on the rear treatment tank 101. The gas monitor 105 is installed on each access channel 103. The joint component is used for introducing tail gas and discharging the treated tail gas, and the distribution component is used for distributing and guiding the incompletely treated waste gas according to the actual gas monitoring situation.

[0030] Specifically, the moving seat 102 is arranged at the bottom of each treatment tank 101. The moving seat 102 consists of a corresponding frame body and four universal wheels arranged at the bottom. By setting the moving seat 102, it is convenient to move a single treatment tank 101. Multiple treatment tanks 101 are connected through the set access channel 103 and the export channel 104. The access channel 103 of the rear treatment tank 101 is adaptively connected to the export channel 104 of the front treatment tank 101, and then fixed by bolts. A corresponding sealing inclined washer is arranged on the outer circle of the export channel 104 in cooperation with the access channel 103 to ensure the stability of the connection of multiple treatment tanks 101;

[0031] The gas monitor 105 is provided on each of the access channels 103. Through the provided gas monitor 105, the quality of the gas exported from each processing tank 101 can be monitored in real time. Before actual operation, the user can also select the corresponding installation quantity of the processing tanks 101 according to the monitoring data of the gas monitors 105 on the multiple processing tanks 101. During actual use, due to the large differences in the quality of the waste gas introduced in various situations, and there are also certain differences in data such as the flow rate of the waste gas export, a processing system composed of a specified number of the processing tanks 101 can be selected for processing. And how to select the appropriate quantity can be determined by the data reflected by the gas monitors 105 on each processing tank 101. Under normal circumstances, when the quantity of the processing tanks 101 and the corresponding processing structures is set too small, the quality of the processed waste gas will be low. At this time, the quantity of the processing tanks 101 and the corresponding processing structures can be appropriately increased. When the quantity of the processing tanks 101 and their corresponding processing structures is large, there will be no significant differences in the gas quality data monitored by the subsequent several processing tanks 101. At this time, the quantity of the processing tanks 101 and the corresponding processing structures can be appropriately reduced, so that the entire processing system can be used more flexibly. Moreover, through the quality monitoring results of the finally discharged waste gas combined with the data monitoring results corresponding to each processing tank 101, they can be matched through the provided corresponding algorithm module, and then the incompletely processed waste gas is introduced into the processing tank 101 with the highest matching degree for secondary processing, rather than directly introducing the incompletely processed waste gas into the initial processing tank 101 for repeated processing. In this way, the processing burden of the front-side processing tanks 101 and the corresponding processing structures can be reasonably shortened, and at the same time, the efficiency of secondary or multiple cycle processing can be accelerated, thereby enhancing the waste gas processing efficiency of the overall system.

[0032] Further, the introduction frame 106 is connected to the access channel 103 of the processing tank 101 arranged at the forefront for introducing the generated waste gas into the processing tank 101 arranged at the forefront; the discharge frame 107 is connected to the export channel 104 of the processing tank 101 arranged at the rearmost for discharging the processed waste gas, and the gas monitor 105 is also provided on the discharge frame 107.

[0033] When this embodiment is in use, the matching structure between the inlet frame 106 and the outlet channel 104 is similar, and the matching structure between the discharge frame 107 and the access channel 103 is similar. So that the inlet frame 106 can be installed on the access channel 103 of the frontmost processing box 101, and the access channel 103 can be installed on the outlet channel 104 of the rearmost processing box 101. The inlet frame 106 is mainly used to introduce the generated waste gas, while the discharge frame 107 is used to discharge the compliant gas after treatment. A corresponding gas monitor 105 is provided on the discharge frame 107 to monitor the quality of the finally treated gas, so as to determine whether the gas meets the discharge standard. It should be noted that the data indicators used can be set according to the actual situation, such as only looking at the sulfur dioxide data indicator or other specified parameters. The subsequent gas quality data detection and the collected data are also of the same type as the corresponding indicator data, so as to facilitate subsequent data matching.

[0034] Furthermore, the selection control valve 201 is installed at the gas outlet end of the discharge frame 107; the transition box 202 is connected to the selection control valve 201, and the gas monitor 105 is installed on the transition box 202; the guiding air pump 203 is connected to the transition box 202; the reflux component is connected to the guiding air pump 203 and is used to shunt and guide the incompletely treated waste gas; the intake component is connected to the transition box 202 and is used to introduce external gas to empty the excess incompletely treated waste gas inside.

[0035] Furthermore, the connecting row frame 204 is connected to the guiding air pump 203; a one-way control valve 205 is installed on each processing box 101; the one-way control valve 205 is connected to the connecting row frame 204 through the connecting pipe 206.

[0036] Furthermore, the fixed bracket 207 is fixedly installed inside the transition box 202; the movable plug 208 is slidably installed on the fixed bracket 207; both sides of the support spring 209 are connected to the fixed bracket 207 and the movable plug 208 respectively.

[0037] When this embodiment is in use, the selection control valve 201 is a three-way control valve. Two interfaces of the selection control valve 201 are respectively connected to the air outlet port of the discharge rack 107 and to the transition box 202. The third interface of the selection control valve 201 needs to be connected to the subsequent gas treatment structure or system according to the actual situation. The transition box 202 is connected to the intake port of the guiding air pump 203. The outlet port of the guiding air pump 203 is connected to the connecting row rack 204. The connecting row rack 204 is provided with a plurality of connectors, so as to be able to be connected to the intake port of the corresponding one-way control valve 205 through the connecting pipe 206. The one-way control valves 205 are arranged in one-to-one correspondence with the treatment boxes 101. The one-way control valves 205 are arranged at the intake ends of the treatment boxes 101. The one-way control valves 205 can introduce the gas inside the connecting row rack 204 into the correspondingly connected treatment boxes 101, and the gas inside the corresponding discharge channels 104 cannot enter the treatment boxes 101 through the one-way control valves 205;

[0038] During the actual working process, the gas monitor 105 arranged on the front side of each treatment box 101 will monitor the quality of the waste gas treated by the treatment box 101 on the front side, and then obtain a relatively stable gas quality data range value. When the gas monitor 105 arranged on the discharge rack 107 monitors that the discharged gas does not meet the preset standard, the selection control valve 201 will guide the gas discharged from the discharge rack 107 into the transition box 202. At the same time, the guiding air pump 203 will also start to work, so as to guide the incompletely treated gas into the transition box 202. Then, the gas monitor 105 arranged on the transition box 202 monitors the value of the introduced incompletely treated gas, and then obtains the specific detection data of the gas that needs to be refluxed. At this time, through the corresponding data processing algorithm set in the control system, the data monitored by the gas monitor 105 arranged on the transition box 202 is matched with the dynamic data range monitored by the gas monitors 105 correspondingly arranged on each treatment box 101, and then the treatment box 101 corresponding to the detection value with a higher matching degree with the detection value of the incompletely treated gas is calculated and determined. Then, the one-way control valve 205 arranged on the treatment box 101 is opened through the corresponding control system, and then the incompletely treated gas is introduced in the corresponding stage;

[0039] The top of the transition box 202 is provided with corresponding air inlet holes, and the movable plug plate is adapted to the corresponding air inlet holes. A corresponding chute is provided inside the movable plug block 208 for cooperating with the protruding column of the fixed bracket 207. The support spring 209 is arranged in the chute of the movable plug block 208. Under normal circumstances, the support spring 209 can squeeze the movable plug block 208 to move upward, thereby blocking the transition box 202. When the air pressure inside the transition box 202 continuously decreases, the external air pressure will press the movable plug block 208 to move downward, thereby opening the top of the transition box 202. In this way, when the discharged gas meets the requirements, the selection control valve 201 will direct the discharged gas to the subsequent treatment system. At this time, the connection relationship between the transition box 202 and the discharge rack 107 will be directly cut off. At this time, there may still be excess untreated gas remaining in the transition box 202. At this time, the guiding air pump 203 will still continue to work to export the gas from the connection row rack 204 and the corresponding one-way control valve 205. In order to completely export the untreated gas inside the transition box 202, the excess untreated gas inside the transition box 202 can be completely exported by borrowing the externally introduced air through the downward movement of the movable plug block 208.

[0040] Preferably, the working assembly provided by the present invention further includes a partition plate 301, a separation baffle 302, a spraying member and a liquid discharging member. The spraying member includes a spraying row rack 303, a conduit bracket 304 and a spraying pump 305. The liquid discharging member includes a separation collection box 401, a sliding baffle 402, a floating block 403 and a discharge rack 404.

[0041] Furthermore, two of the partition plates 301 are fixedly installed in each treatment box 101; a plurality of the separation baffles 302 are arranged between the two partition plates 301; the spraying member is installed on each treatment box 101 for washing the waste gas introduced therein; the liquid discharging member is arranged at the bottom of each treatment box 101 for discharging the accumulated cleaning liquid.

[0042] Furthermore, two of the spraying row racks 303 are provided inside each treatment box 101. One spraying row rack 303 is arranged at the inner top of the treatment box 101, and the other spraying row rack 303 is arranged at the bottom of the partition plate 301; the conduit bracket 304 is connected to the two spraying row racks 303 and is installed on the top of the treatment box 101; the spraying pump 305 is connected to the conduit bracket 304 and is installed on the top of the treatment box 101.

[0043] When this embodiment is in use, the two partition plates 301 divide the interior of the treatment box 101 into an "S"-shaped area, so as to increase the flow distance of the gas and ensure that the gas and the sprayed washing liquid can be fully matched. A plurality of partition baffles 302 are arranged between the two partition plates 301. The arranged partition baffles 302 are mainly used to disrupt the flowing gas, thereby increasing the contact area between the gas and the sprayed washing liquid;

[0044] The washing liquid enters the conduit support 304 through the spray pump 305, and then is sprayed out from the two spray racks 303 provided through the guidance of the conduit support 304. The two spray racks 303 respectively correspond to the two partition plates 301 provided, so as to be able to more fully wash the gas flowing in the area partitioned by the partition plates 301.

[0045] Furthermore, the partition collection box 401 is installed at the bottom of the treatment box 101. Two independent storage areas are provided in the partition collection box 401. The two sliding shutter plates 402 are respectively slidably installed in the two corresponding storage areas of the partition collection box 401; a floating block 403 is fixedly installed on each sliding shutter plate 402; the discharge rack 404 is connected to the partition collection box 401.

[0046] When this embodiment is in use, the partition collection box 401 is provided at the bottom of each treatment box 101. The partition collection box 401 respectively corresponds to the two main spray treatment areas where the treatment box 101 is disassembled. Guide grooves are provided at the bottoms of the two treatment areas where the treatment box 101 performs spraying, so as to be able to collect the sprayed washing liquid through the partition collection box 401. Two independent storage areas are provided inside the partition collection box 401 to prevent the gas from flowing through the partition collection box 401 and ensure that the gas can pass through both sides of each treatment box 101 for spraying and washing;

[0047] A discharge rack 404 is provided on the side of the partitioned collection box 401. Through the provided discharge rack 404, the washing liquid collected in the partitioned collection box 401 can be discharged. Corresponding discharge grooves are provided on the sides of the two collection areas of the partitioned collection box 401, and corresponding sliding shutter plates 402 are provided on each discharge groove for shielding and sealing. A floating block 403 is fixed to the top of the side of each sliding shutter plate 402. When the washing liquid in a specified area of the partitioned collection box 401 is collected to a certain amount, the corresponding floating block 403 will lift the sliding shutter plate 402 under the action of buoyancy, thereby completing the discharge of the excess washing liquid. By adopting such a method, the washing liquid collected in the partitioned collection box 401 can be automatically discharged, and at the same time, it can be avoided that the waste gas in the treatment box 101 is discharged together with the washing liquid when the washing liquid is discharged. Since the sliding shutter plate 402 and the floating block 403 need to collect a certain amount of washing liquid to open the discharge groove in the corresponding area of the partitioned collection box 401, there will always be a certain amount of washing liquid in the corresponding area of the partitioned collection box 401. Therefore, the waste gas in the corresponding treatment box 101 cannot be discharged from the discharge groove of the partitioned collection box 401.

[0048] Please refer to Figure 8 , a method for treating dry tail gas containing ammonium sulfate, using the above-mentioned dry tail gas treatment system containing ammonium sulfate, including the following steps:

[0049] S1: Through the access channels 103 and the export channels 104 provided in multiple treatment boxes 101, they are spliced and matched with each other to form a treatment system composed of multiple treatment boxes 101;

[0050] S2: The waste gas is introduced from the access channel 103 of the treatment box 101 arranged at the frontmost side through the joint member, and then exported from the export channel 104 of the treatment box 101 arranged at the rearmost side. Then, the gas quality data of each treatment box 101 is collected through the gas monitor 105 provided on each access channel 103;

[0051] S3: It is judged whether the requirements for discharge are met by detecting the quality of the finally treated gas. When the requirements for discharge are met, the gas can be directly discharged. If the requirements are not met, the quality data of the finally treated gas can be analyzed through the distribution member, so as to introduce the incompletely treated gas into the appropriate treatment box 101 for secondary treatment.
