Description

Technical Field

[0001] The invention relates to the technical field of dust removal and desulfurization equipment, in particular to environmentally friendly dust removal and desulfurization equipment. Background Art

[0002] Existing industries generate a large amount of waste gas during the production process. These waste gases contain various harmful components, among which sulfur-containing substances have a great impact on the air. Direct discharge into the atmosphere will seriously affect the atmospheric environment and cause harm to the human body. Therefore, the existing industrial waste gas will be treated by dust removal and desulfurization equipment before being discharged. The existing dust removal and desulfurization equipment is to discharge the gas into the equipment, and then spray liquid through the spray equipment to perform dust removal and desulfurization operations on the gas. However, there are still some problems in the use of the existing dust removal and desulfurization equipment, as follows: When the existing dust removal and desulfurization equipment is in use, a liquid holding area will be formed at the bottom of the equipment, and an exhaust gas inlet is arranged on the top. When the exhaust gas enters this area, the liquid sprayed from the top will be used to settle and collect it, and then it will be pumped out again through the reflux pump and sprayed out from the top for continued circulation. In this way, the dust and impurities mixed in the bottom liquid cannot be separated well, resulting in damage to the circulation pump. At the same time, the increasingly turbid treatment liquid will also gradually reduce its treatment effect, and finally lead to excessive dirt and impurities inside the equipment, requiring frequent shutdown for maintenance, which not only reduces the use efficiency of the equipment, but also cannot guarantee the equipment's treatment effect on the exhaust gas. For this reason, we propose an environmentally friendly dust removal and desulfurization equipment. Summary of the invention

The inner part is driven by the rotation of the stirring wheel 11 at the bottom to rotate the liquid and impurities therein to generate centrifugal force. Under the action of the centrifugal force, the internal liquid and the impurities therein are driven to rotate together and adhere to the inside of the filter ring net 43 on the side, so that the impurities are separated, and the liquid can flow through the filter ring net 43 to the outside of the separation cylinder 2 for subsequent circulation.

[0025] See also Figure 2-7 An environmentally friendly dust removal and desulfurization device includes a collecting assembly 14, which includes a scraping groove 141, a collecting groove 142 is fixedly installed at the bottom end of the scraping groove 141, a telescopic sleeve rod 143 is fixedly installed on one side of the scraping groove 141, a transverse plate 144 is fixedly installed on the end of the telescopic sleeve rod 143, a first spring 145 is fixedly installed on one side of the scraping groove 141, a locking pin rod 146 is inserted and movably installed on the transverse plate 144, and a limited position rotating block 147 is movably installed on the other side of the scraping groove 141; In this embodiment, it should be noted that a straight groove running through the upper and lower ends is provided in the middle of the other side of the scraper groove 141, and the position of the straight groove corresponds to the position of the abutment block 45. The collecting groove 142 is located on the side where the telescopic sleeve 143 is located and is fixedly connected to the lower part of the scraper groove 141, and is connected to the inside of the scraper groove 141. The other end of the first spring 145 is fixedly mounted on the cross plate 144, and a circular groove is provided at the end of the support rod 13. The cross plate 144 is clamped at the end of the support rod 13. The locking pin 146 runs through the cross plate 144 and the circular groove at the end of the support rod 13. The limit switch 147 is a one-way downward limit setting. The rotation limit setting allows the resistance block 45 to resist the side of the limit rotating block 147 during the upward movement, thereby causing the scraping groove 141 to continuously compress the first spring 145 until the resistance block 45 completely moves upward and exceeds the limit rotating block 147, and then rebounds under the action of the first spring 145, so that the edge of the scraping groove 141 can fit the surface of the filter ring net 43, and then the dust and impurities adhering to the surface can be scraped off during the downward movement, thereby achieving the self-cleaning effect of the equipment, and with the help of the storage capacity of the collection groove 142, the maintenance cycle of the equipment can be greatly extended, thereby improving the use efficiency of the equipment.

[0026] See also Figure 2-8An environmentally friendly dust removal and desulfurization device includes an air outlet component 15, the air outlet component 15 includes an air outlet pipe 151, and horizontal positioning plates 152 are fixedly installed on both sides of the air outlet pipe 151. An air outlet groove 153 is opened at the bottom of the air outlet pipe 151, and a movable opening and closing component 154 is movably connected to the horizontal positioning plate 152; In this embodiment, it should be noted that the interior of the air outlet pipe 151 is connected with the interior of the air inlet pipe 12, a groove is provided in the middle of the two horizontal positioning plates 152, and the air outlet pipe 151 is located at the bottom end of the separation cylinder 2 and is arranged in the liquid. In this way, the air pressure generated by the input gas in the air outlet pipe 151 can be used to push the movable opening and closing component 154 to move, thereby opening the air outlet groove 153 so that the gas is sprayed into the liquid retained below, thereby achieving preliminary dust and impurity filtration and separation, improving the gas treatment effect, and when shutdown is required, the movable opening and closing component 154 will automatically close as the gas pressure gradually decreases, thereby avoiding liquid reflux and ensuring the service life of the equipment.

[0027] See also Figure 8-9 An environmentally friendly dust removal and desulfurization device includes a movable opening and closing assembly 154, the movable opening and closing assembly 154 includes a straight plate 1541, a vertical plate 1542 is fixedly installed on one side of the top of the straight plate 1541, a closed end 1543 is evenly fixedly installed on the bottom end of the straight plate 1541, and a second spring 1544 is fixedly installed on one side of the vertical plate 1542; In this embodiment, it should be noted that card slots are provided on both sides of the straight plate 1541, and the card slots are slidably arranged on the horizontal positioning plate 152, and the closed end 1543 is arranged to fit the bottom end of the inside of the air outlet pipe 151 and the coverage range is larger than the air outlet groove 153, and one end of the second spring 1544 is located at the inner end of the air outlet pipe 151 and is fixedly installed. In this way, when the machine is shut down, the elastic force of the second spring 1544 can be used to block the air outlet groove 153 with the closed end 1543, thereby avoiding the reflux of liquid inside the outer cylinder 1 and ensuring the use effect of the air outlet component 15.

[0028] Working principle: gas enters from the air inlet pipe 12 and then enters the inside of the air outlet pipe 151. The increase in air pressure will compress the second spring 1544, which in turn drives the closed end 1543 to open the air outlet groove 153. The gas is ejected from the air outlet groove 153 into the liquid at the bottom end of the outer cylinder 1. The gas flows upward through the liquid discharge. The circulation pump 16 starts to pump the liquid inside the outer cylinder 1 into the circulation pipe 17, and then enters the intermediate ring cylinder 71 and the branch pipe 72, and finally sprays out from the spray head 73. The sprayed water mist will settle the impurity particles in the gas and flow downward to the bottom end of the outer cylinder 1. The external drive motor 5 at the top will also start at the same time to drive the drive rod 6 to rotate, and the drive rod 6 will drive the spray assembly 7 as a whole and the stirring wheel 11 to rotate. The rotation of the stirring wheel 11 will make the liquid as a whole The rotation of the body generates centrifugal force, which causes the dust and impurities therein to continuously accumulate and gather on the surface of the filter ring net 43 under the action of centrifugal force. When the surface of the filter ring net 43 needs to be cleaned, just start the electric telescopic rod 18, the electric telescopic rod 18 drives the filter ring net 43 to move upward, and the resistance block 45 will push the scraper groove 141 to compress the first spring 145 under the action of the limit rotating block 147. When the resistance block 45 completely passes through the limit rotating block 147, the scraper groove 141 rebounds and fits to the surface of the filter ring net 43, and then the filter ring net 43 is driven to move downward through the contraction of the electric telescopic rod 18, so that the scraper groove 141 scrapes the dust and impurities on the surface of the filter ring net 43 and collects them in the collecting groove 142, thereby ensuring the permeability of the filter ring net 43 and realizing the continuous use of the equipment.
