Description

Technical Field

[0001] The invention belongs to the technical field of gas purification and treatment, and relates to an industrial waste gas purification and treatment discharge device. Background Art

[0002] During industrial production, waste gas emissions have become a major source of air pollution. With the continuous upgrading of environmental protection policies and increasingly stringent emission standards in my country and around the world, efficiently and stably purifying industrial waste gas to ensure that its emission indicators meet environmental requirements has become a core technical challenge that industrial enterprises urgently need to address.

[0003] In the existing industrial production process, many enterprises will generate a certain amount of harmful waste gas. In the process of harmful waste gas emission, in order to reduce its impact on the environment, the existing treatment method is usually to introduce the waste gas into the purification device through a pipeline, use the filter to intercept and adsorb the impurities in the waste gas, and use the waste gas purification liquid to further treat the gas, and finally discharge the qualified gas into the atmosphere. However, during the continuous operation of the purification device, as the waste gas is continuously sucked into the purification device, the filter equipment in the purification device will gradually accumulate pollutants in the process of separating impurities, causing the filter equipment inside the purification device to be blocked. After the filter equipment is blocked, the purification efficiency will be reduced, and the filter will need to be stopped to replace the filter, which affects the production continuity and is inconvenient to operate.

DETAILED DESCRIPTION

[0027] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the invention can be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and will fully convey the scope of the invention to those skilled in the art.

[0028] An industrial waste gas purification and treatment emission device, such as Figure 1-Figure 5 As shown, it includes a base frame 1, a processing box 2, an air inlet pipe 3, an air outlet pipe 4, a screening mechanism, a processing mechanism and a cleaning mechanism. The upper part of the base frame 1 is connected to the processing box 2, the left side of the processing box 2 is connected to the air inlet pipe 3, and the right side of the processing box 2 is connected to the air outlet pipe 4. A screening mechanism for screening impurities in the exhaust gas and a processing mechanism for purifying the gas are provided in the processing box 2, and a cleaning mechanism for cleaning the screening mechanism is provided between the processing box 2 and the screening mechanism.

[0029] like Figure 2-Figure 4 As shown, the screening mechanism includes an isolation plate 51, a mounting frame 52, a treatment cylinder 53 and an arc-shaped screening plate 54. The isolation plate 51 is connected to the left side of the treatment box 2, and the mounting frame 52 is connected to the right side of the treatment box 2. A plurality of treatment cylinders 53 are evenly spaced between the isolation plate 51 and the mounting frame 52. A plurality of arc-shaped screening plates 54 are evenly spaced on the treatment cylinder 53. The left side of the treatment cylinder 53 passes through the isolation plate 51 and is connected to the left side of the treatment box 2, so that the exhaust gas entering the intake pipe 3 will enter the treatment cylinder 53.

[0030] like Figure 2-Figure 4As shown, the processing mechanism includes an outer cylinder 61, a lower frame 62, an injection pipe 63, a spray pipe 64 and an atomizing nozzle 65. The outer side of the processing cylinder 53 is sleeved with an outer cylinder 61, the left side of the outer cylinder 61 is connected to the isolation plate 51, and the bottom of the outer cylinder 61 is connected to the lower frame 62. The right side of the processing box 2 is evenly spaced from top to bottom with multiple injection pipes 63, and the left side of the injection pipe 63 is evenly spaced with multiple groups of spray pipes 64. Each group of spray pipes 64 is provided with two, and the two spray pipes 64 of each group are respectively connected to the front and rear sides of multiple lower frames 62. The two spray pipes 64 of each group are close to each other on the side where they are evenly spaced and connected with multiple atomizing nozzles 65. The atomizing nozzles 65 extend into the lower frame 62.

[0031] like Figure 5 As shown, the cleaning mechanism includes a cleaning scraper 81, a driving motor 82 and a connecting frame 83. The connecting frame 83 is connected to the left side of the processing cylinder 53, and the cleaning scraper 81 is rotatably connected to the connecting frame 83. The driving motor 82 is installed on the right side of the processing cylinder 53, and the output shaft of the driving motor 82 is connected to the cleaning scraper 81 so that the driving motor 82 can drive the cleaning scraper 81 to rotate.

[0032] When it is necessary to purify industrial waste gas before discharging it, this device can be used. When in use, the industrial waste gas pipeline is connected to the air inlet pipe 3. The industrial waste gas will enter the treatment box 2 through the air inlet pipe 3, and then enter the treatment cylinder 53 through the isolation plate 51. The gas will then be discharged through the arc-shaped screening plate 54. When the gas passes through the arc-shaped screening plate 54, the arc-shaped screening plate 54 can screen the particles in the gas, thereby filtering the gas before discharging it. The discharged gas enters the outer cylinder 61 and is then discharged through the lower frame 62. In this process, waste gas purification liquid can be injected through the liquid injection pipe 63, and the waste gas purification liquid will enter the liquid spray pipe 64, and then be atomized and sprayed into the lower frame 62 through the atomizing nozzle 65. The sprayed waste gas purification liquid and the waste gas The gas reacts to purify the waste gas, and the purified waste gas is discharged through the lower frame 62, and finally discharged through the exhaust pipe 4. During the treatment process, the particles in the waste gas will adhere to the arc-shaped screening plate 54. When there are many attached particles, the driving motor 82 can be controlled to drive the cleaning scraper 81 to rotate. The rotation of the cleaning scraper 81 can scrape off the particles attached to the arc-shaped screening plate 54. The scraped impurities are blown to the right side of the treatment cylinder 53 by the incoming gas, so that the impurities accumulate on the right side of the treatment cylinder 53. In this way, the industrial waste gas can be purified before being discharged, and the arc-shaped screening plate 54 can be automatically cleaned to avoid excessive impurities on the arc-shaped screening plate 54 hindering the operation of the entire device.

[0033] like Figure 3 and Figure 4As shown, it also includes a moisture absorption mechanism, which includes an air outlet frame 71, a partition net 72 and a moisture absorption sponge 73. The bottom of the lower frame 62 is connected to the air outlet frame 71, the upper part of the air outlet frame 71 is connected to the partition net 72, and a moisture absorption sponge 73 is placed on the top of the partition net 72. The moisture absorption sponge 73 can absorb moisture from the gas.

[0034] When the gas is discharged through the lower frame 62, it will be discharged into the air outlet frame 71. When the gas passes through the air outlet frame 71, it will first pass through the hygroscopic sponge 73 and the partition net 72. The moisture in the gas is removed by the hygroscopic sponge 73, and then the gas is discharged to avoid excessive moisture when the gas is discharged, which affects the surrounding environment.

[0035] like Figure 6 and Figure 7 As shown, an impurity collection mechanism is also included, which includes a reduction motor 91, a threaded rod 92, a blocking plate 93, a collection frame 94 and a connecting frame 95. A reduction motor 91 is installed on the left side of the top of the processing box 2, and a threaded rod 92 is connected to the output shaft of the reduction motor 91. A blocking plate 93 is slidably connected to the left side of the isolation plate 51, and the blocking plate 93 can slide up and down along the isolation plate 51. The blocking plate 93 is threadedly engaged with the threaded rod 92, and the blocking plate 93 can slide to block the left side of the processing cylinder 53. A plurality of connecting frames 95 are evenly spaced from top to bottom on the right side of the processing box 2. The connecting frame 95 is connected to the bottom of the processing cylinder 53 close to it, and a collection frame 94 is slidably connected inside the connecting frame 95.

[0036] When the impurities are blown to the right side of the treatment cylinder 53, the impurities will pass through the connecting frame 95 and enter the collecting frame 94. The impurities can be collected through the collecting frame 94. When the impurities in the collecting frame 94 need to be cleaned, the driving motor 82 is controlled to drive the threaded rod 92 to rotate so that the threaded rod 92 blocks the air inlet of the treatment cylinder 53 at the position that needs to be cleaned. Then, the collecting frame 94 corresponding to the treatment cylinder 53 is pulled out, and the impurities inside the collecting frame 94 are dumped. After dumping, the collecting frame 94 is put back, and then the driving motor 82 is controlled to drive the blocking plate 93 to no longer block the air inlet end of the treatment cylinder 53, thereby realizing the function of collecting the processed impurities.

[0037] like Figures 8-10 As shown, it also includes a waste liquid collection mechanism, which includes a reflux frame 101, a reflux pipe 102 and a buoyancy valve 103. The reflux frame 101 is connected to the right side of the base frame 1, and the reflux pipe 102 is connected between the right sides of the bottom of multiple air outlet frames 71. The end of the reflux pipe 102 extends into the reflux frame 101, and the part of the reflux pipe 102 extending into the air outlet frame 71 is provided with a buoyancy valve 103.

[0038] After the hygroscopic sponge 73 absorbs moisture, the water will drip onto the bottom of the air outlet frame 71. As the dripping water gradually increases, the water will drive the buoyancy valve 103 to float up, thereby opening the buoyancy valve 103. At this time, the water will flow back to the reflux frame 101 through the reflux pipe 102, thereby collecting the wastewater generated during the treatment process.

[0039] like Figure 11 As shown, a molecular sieve 11 is also included. The molecular sieve 11 is provided on the right side of the processing box 2. The molecular sieve 11 is used to absorb moisture in the gas, thereby further removing the moisture mixed in the gas.
