[0002] An efficient desulfurization and dust removal device is an environmental protection device applied in the industrial production process for treating air pollutants. In order to reduce air pollution and protect the ecological environment and human health, an efficient desulfurization and dust removal device is required at this time.

[0003] The Chinese patent discloses an efficient desulfurization and dust removal device with the publication number of CN208642139U. The technical solution disclosed in this patent document is as follows: It includes a desulfurization tower. The upper end of the desulfurization tower is connected with a flue gas pipeline for discharging flue gas. The structural shape of the flue gas pipeline is S-shaped. The flue gas pipeline is connected with a fan. The fan blows the flue gas into a chimney connected to the fan for discharge.

However, one or more embodiments can also be implemented by those skilled in the art without these specific details.

[0026] As Figures 1 - 5 shown, the high-efficiency desulfurization and dust removal energy-saving equipment includes a desulfurization bin 1, and a desulfurizer recovery mechanism 2 is arranged on the desulfurization bin 1. The desulfurizer recovery mechanism 2 includes a transfer air pipe 22. The transfer air pipe 22 is fixedly connected to the top of the desulfurization bin 1. One end of the transfer air pipe 22 away from the desulfurization bin 1 is fixedly connected to a recovery bin 23. A copper pipe 25 is fixedly installed on the inner wall of the recovery bin 23. The left end of the copper pipe 25 extends to the left side of the recovery bin 23 and is fixedly connected to a shunt pipe 26. The left side of the shunt pipe 26 is fixedly connected to a fan 27. The right end of the copper pipe 25 extends to the right side of the recovery bin 23. A diversion plate 28 is fixedly installed on the inner wall of the recovery bin 23. A pipe groove 281 is formed on the side surface of the diversion plate 28. The middle part of the copper pipe 25 is located in the inner cavity of the pipe groove 281. Square grooves 282 are formed at the top and bottom of the diversion plate 28. A weight reduction groove 283 is formed on the side surface of the diversion plate 28. Through the design of the transfer air pipe 22, the desulfurized flue gas in the desulfurization bin 1 can be guided into the inner cavity of the recovery bin 23 for flow. At the same time, the fan 27 is controlled to work, absorb external air and then transport it through the shunt pipe 26 to the inside of the copper pipe 25 for flow. When the flue gas inside the recovery bin 23 passes through the inner cavity of the pipe groove 281, it can be in full contact with the outer surface of the copper pipe 25, thereby promoting the condensation of the desulfurizer evaporated inside the flue gas on the outer surface of the copper pipe 25, avoiding the problem that the evaporated desulfurizer is discharged with the flue gas, resulting in waste.

[0027] In this embodiment, an extended support arm 21 is fixedly installed on the outer surface of the recovery bin 23. One end of the extended support arm 21 away from the recovery bin 23 is fixedly connected to the outer wall of the desulfurization bin 1. The bottom of the recovery bin 23 is fixedly connected to an expansion bin 24. A valve 241 is fixedly connected to the bottom of the expansion bin 24. An exhaust pipe 242 is fixedly connected to the right side of the expansion bin 24. Support legs 11 are fixedly installed on the outer wall of the desulfurization bin 1. The desulfurizer condensed on the copper pipe 25 will gather at the bottom of the inner cavity of the expansion bin 24 under the action of gravity. Opening the valve 241 can recycle and utilize the desulfurizer, thereby saving the consumption of consumables. Through the design of the weight reduction groove 283, the overall material and weight of the diversion plate 28 are reduced. Through the design of the pipe groove 281 and the square groove 282, the waste gas can be in full contact with the outer surface of the copper pipe 25, improving the sufficiency of condensation collection.

[0028] In this embodiment, an intake pipe 12 is fixedly connected to the front of the desulfurization bin 1. A filter bin 13 is fixedly connected to the middle of the intake pipe 12. Inclined plates 131 are fixedly installed on the inner wall of the filter bin 13. The number of the inclined plates 131 is set to two. A stainless steel filter plate 132 is fixedly installed on the inner wall of the upper inclined plate 131, and a non-woven fabric filter plate 133 is fixedly installed on the inner wall of the lower inclined plate 131. A plug-in cover plate 134 is movably inserted into the front of the filter bin 13. A hollow ring 14 is fixedly installed on the inner wall of the desulfurization bin 1. A connecting pipe 141 is fixedly connected between two adjacent hollow rings 14. An atomizing nozzle 143 is fixedly connected to the inner surface of the hollow ring 14. A desulfurizing agent filling pipe 144 is fixedly connected to the top of the topmost hollow ring 14. The end of the desulfurizing agent filling pipe 144 away from the hollow ring 14 extends to the top of the desulfurization bin 1. Thin rods are fixedly installed on the inner surface of the hollow ring 14, and a middle baffle 142 is fixedly installed at one end of the thin rod away from the inner surface of the hollow ring 14. The output end of an externally connected desulfurizing agent output pump is pre-connected to the end of the desulfurizing agent filling pipe 144. By controlling the externally connected desulfurizing agent output pump to work, desulfurizing agent can be conveyed into the interior of the hollow ring 14. Through the design of the connecting pipe 141, the inner cavities of several hollow rings 14 can be communicated. Then, the desulfurizing agent can be output from the atomizing nozzle 143 to complete the desulfurization treatment of the flue gas. Through the blockage of the middle baffle 142, the flue gas and the desulfurizing agent can be fully contacted to improve the desulfurization effect. An externally connected flue gas output pipe is connected to the top of the intake pipe 12. The flue gas will pass through the inner cavity of the filter bin 13 and enter the desulfurization bin 1. Through the cooperation of the stainless steel filter plate 132 and the non-woven fabric filter plate 133, the filtering and dust removal treatment of the flue gas can be completed. The plug-in cover plate 134 is pulled out from the side of the filter bin 13, and then the filter surfaces of the stainless steel filter plate 132 and the non-woven fabric filter plate 133 can be cleaned.

[0029] The working principle of the high-efficiency desulfurization, dust removal and energy-saving equipment of the present utility model is as follows: An externally connected flue gas output pipe is pre-connected to the top of the intake pipe 12. The flue gas will pass through the inner cavity of the filter bin 13 and enter the desulfurization bin 1. Through the cooperation of the stainless steel filter plate 132 and the non-woven fabric filter plate 133, the filtering and dust removal treatment of the flue gas can be completed. The output end of an externally connected desulfurizing agent output pump is pre-connected to the end of the desulfurizing agent filling pipe 144. By controlling the externally connected desulfurizing agent output pump to work, the desulfurizing agent can be output from the atomizing nozzle 143 to complete the desulfurization treatment of the flue gas. The transfer air pipe 22 can guide the desulfurized flue gas in the desulfurization bin 1 to flow in the inner cavity of the recovery bin 23. At the same time, the fan 27 is controlled to work to absorb external air and then convey it through the shunt pipe 26 to flow inside the copper pipe 25. When the flue gas inside the recovery bin 23 flows through the inner cavity of the pipe groove 281, it can be fully contacted with the outer surface of the copper pipe 25, so as to promote the condensation of the desulfurizing agent evaporated inside the flue gas on the outer surface of the copper pipe 25. During maintenance, the valve 241 is opened to recover and utilize the desulfurizing agent.
