Description

Technical Field

[0001] The present invention specifically relates to the technical field of waste gas treatment and purification, and specifically relates to a multiple processing and purification device for industrial waste gas treatment. Background Art

[0002] There are a large number of chemical components in industrial waste gas, the most common of which is sulfur dioxide. Sulfur dioxide is a major air pollutant. When it is discharged into the atmosphere, it will react with water vapor in the atmosphere to produce sulfurous acid, which is then oxidized into sulfuric acid to form acid rain. In order to protect the environment and human health, waste gas containing sulfur dioxide needs to be purified to meet the air pollutant emission standards; Currently, the most widely used desulfurization method is wet desulfurization. This method uses limestone or lime slurry as a desulfurizer. When the exhaust gas enters the absorption tower, the nozzle in the absorption tower sprays limestone slurry downward to react with the limestone slurry.

[0003] However, in practice, people have noticed that the current spray structure usually uses multiple spray layers for coverage, but it can only play a good mixing role on the exhaust gas passing around the spray head, while the exhaust gas that is far away from the spray head has less contact with the desulfurizer after being sprayed out. This causes uneven mixing of the exhaust gas and the desulfurizer, which is likely to affect the subsequent desulfurization treatment effect. Summary of the invention

[0004] The purpose of the present invention is to provide a multi-process purification device for industrial waste gas treatment, which uses a rotatable internal spray structure to ensure that the waste gas and the desulfurizer solution can be evenly contacted, and the filter screen arranged under each nozzle can ensure that the desulfurizer solution and the waste gas are fully mixed, thereby improving the desulfurization effect. To solve the technical problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions: A multi-processing purification device for industrial waste gas treatment, comprising a primary treatment box and a spray tower, wherein a connecting pipe is fixedly connected to the top of the primary treatment box, and the other end of the connecting pipe is fixedly connected to the spray tower, and a liquid outlet pipe and an air inlet pipe are respectively fixedly connected to the side of the primary treatment box away from the connecting pipe; The inner side of the primary treatment box is also fixedly connected with a filter plate, and the inner side of the primary treatment box is also movably connected with a rotary spray rack, and the rotary spray rack is movably connected to the filter plate.

[0006] As a further technical solution of the present invention, the rotating spray rack includes a hollow rotating cylinder, and both ends of the hollow rotating cylinder are integrally provided with a rotating support shaft, wherein the rotating support shaft at the bottom of the hollow rotating cylinder is movably connected to the primary treatment box through a bearing, and the rotating support shaft at the other end passes through the primary treatment box and extends to above the primary treatment box.

[0007] As a further technical solution of the present invention, the hollow rotating cylinder is arranged inside the primary treatment box, and the end of the hollow rotating cylinder passes through the filter plate.

[0009] As a further technical solution of the present invention, each of the rotating arms is movably connected to a protective roller at one end away from the hollow rotating cylinder, and the side of the protective roller is in contact with the inner wall of the primary processing box, while the end of the rotating arm is connected to the inner side of the hollow rotating cylinder.

[0010] As a further technical solution of the present invention, each rotating arm side surface is also fixedly connected with an atomizing nozzle in a rectangular array, and the atomizing nozzle is arranged horizontally, and the atomizing nozzles on the multiple groups of rotating arms are oriented in the same direction.

[0011] As a further technical solution of the present invention, the end of the spray tower is connected to the secondary treatment box on the side through a pipe, and the other end of the secondary treatment box is fixedly connected to an exhaust fan through a pipe, and a smoke exhaust pipe is provided on the side of the exhaust fan, and the outlet of the exhaust fan is connected to the smoke exhaust pipe through a pipe.

The dust collecting filters, deodorizing filters, activated carbon filters and air filter elements are clamped on the inner side of the card plates; an air outlet is opened at the end of the filter box.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention uses a horizontally arranged atomizing nozzle to drive the rotating spray frame to rotate by using a reaction force when spraying the solution, and the rotating spray frame is also provided with a plurality of rotating arms, thereby increasing the contact surface between the exhaust gas and the desulfurization solution, so that the exhaust gas can contact the desulfurizer more evenly, thereby improving the desulfurization effect; In the present invention, the excess desulfurizing agent solution will fall onto the filter screen, and a water film will be formed on the filter screen by the tension of the desulfurizing agent solution.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-10 The embodiment of the present invention provides a multi-process purification device for industrial waste gas treatment, including a primary treatment box 1 and a spray tower 2, wherein a connecting pipe 6 is fixedly connected to the top of the primary treatment box 1, and the other end of the connecting pipe 6 is fixedly connected to the spray tower 2, and a liquid outlet pipe 7 and an air inlet pipe 9 are respectively fixedly connected to the side of the primary treatment box 1 away from the connecting pipe 6; The inner side of the primary treatment box 1 is also fixedly connected with a filter plate 10 , and the inner side of the primary treatment box 1 is also movably connected with a rotary spray rack 8 , and the rotary spray rack 8 is movably connected to the filter plate 10 .

[0028] In this embodiment, the rotating spray rack 8 includes a hollow rotating cylinder 81, and both ends of the hollow rotating cylinder 81 are integrally provided with a rotating support shaft 82, wherein the rotating support shaft 82 at the bottom of the hollow rotating cylinder 81 is movably connected to the primary treatment box 1 through a bearing, and the rotating support shaft 82 at the other end passes through the primary treatment box 1 and extends to the top of the primary treatment box 1.

[0029] Furthermore, the hollow rotating cylinder 81 is arranged inside the primary treatment box 1 , and the end of the hollow rotating cylinder 81 passes through the filter plate 10 .

[0030] More specifically, the outer side of the hollow rotating cylinder 81 is provided with multiple groups of rotating arms 83 in a rectangular array, and the multiple groups of rotating arms 83 are spaced apart from the filter plate 10, and each group of rotating arms 83 is fixedly connected to the outer side of the hollow rotating cylinder 81 in a circular array.

[0031] To be more specific, each of the rotating arms 83 is movably connected to a protective roller 84 at one end away from the hollow rotating cylinder 81, and the side of the protective roller 84 is in contact with the inner wall of the primary processing box 1, while the end of the rotating arm 83 is connected to the inner side of the hollow rotating cylinder 81.

[0032] Furthermore, each of the rotating arms 83 has atomizing nozzles 85 fixedly connected to the side surface in a rectangular array, and the atomizing nozzles 85 are arranged horizontally, and the atomizing nozzles 85 on the multiple groups of rotating arms 83 are oriented in the same direction.

[0033] Furthermore, the end of the spray tower 2 is connected to the secondary treatment box 3 on the side through a pipe, and the other end of the secondary treatment box 3 is fixedly connected to the exhaust fan 4 through a pipe, and a smoke exhaust pipe 5 is provided on the side of the exhaust fan 4, and the outlet of the exhaust fan 4 is connected to the smoke exhaust pipe 5 through a pipe.

[0034] Furthermore, the filter plate 10 includes a support frame 101 fixedly connected to the primary processing box 1 , a filter screen 102 is embedded in each of the support frames 101 , and the hollow rotating cylinder 81 passes through the inner side of the filter screen 102 .

[0035] By adopting the above technical solution, the external feed pump is first connected to the rotating support shaft 82 on the upper part of the hollow rotating cylinder 81 by using a rotating joint, and then the feed pump sends the desulfurizer solution into the hollow rotating cylinder 81 through the rotating support shaft 82, and then the hollow rotating cylinder 81 evenly sends it to the rotating arm 83, and finally it is sprayed out by the atomizing nozzle 85 on the side of the rotating arm 83. Since the atomizing nozzle 85 is horizontally arranged, the reaction force of the atomizing nozzle 85 during the spraying process will push the rotating arm 83 to move, so that the rotating arm 83 rotates with the hollow rotating cylinder 81 as the axis, and the excess desulfurizer solution falls onto the filter 102, forming a water film on the inner side of the filter 102, thereby ensuring sufficient contact between the desulfurizer solution and the exhaust gas.

[0036] Furthermore, the liquid outlet pipe 7 is located below the primary treatment box 1, and the end of the liquid outlet pipe 7 is connected to the inner side of the primary treatment box 1, the air inlet pipe 9 is located above the liquid outlet pipe 7, and the connection between the air inlet pipe 9 and the primary treatment box 1 is located below the filter plate 10.

[0037] More specifically, a feed port is provided in the rotating support shaft 82 disposed above the hollow rotating cylinder 81 , and the desulfurizing agent solution enters the hollow rotating cylinder 81 through the feed port in the rotating support shaft 82 , and is then evenly distributed to the rotating arm 83 by the hollow rotating cylinder 81 .

[0038] Furthermore, the portion of the rotating support shaft 82 on the top of the hollow rotating cylinder 81 extending to the outside of the primary treatment box 1 is fixedly connected with a rotating joint to ensure that the desulfurizing agent solution can be normally supplied while the rotating spray rack 8 rotates.

[0039] In this embodiment, a filter box 11 is placed inside the secondary treatment box 3, and multiple groups of card plates 111 are integrally formed on both sides of the filter box 11. A dust filter 112, a deodorizing filter 113, an activated carbon filter 114 and an air filter element 115 are respectively installed inside the card plates 111 along the air inlet direction. The dust filter 112, the deodorizing filter 113, the activated carbon filter 114 and the air filter element 115 are clamped on the inner side of the card plates 111; an air outlet 116 is opened at the end of the filter box 11.

[0040] The working principle of the present invention is: when in use, the exhaust gas is first introduced from the inner side of the intake pipe 9, and then the external supply pump is connected to the rotating joint above the rotating support shaft 82 through the pipeline to send the desulfurizer solution into the hollow rotating cylinder 81 through the rotating support shaft 8, and then evenly distributed to the rotating arm 83 through the hollow rotating cylinder 81, and finally sprayed out through the atomizing nozzle 85 on the side of the rotating arm 83. Since the atomizing nozzle 85 is arranged horizontally, the reaction force of the atomizing nozzle 85 during the spraying process will push the rotating arm 83 to move, so that the rotating arm 83 rotates with the hollow rotating cylinder 81 as the axis, and the excess desulfurizer solution falls onto the filter screen 102, forming a water film on the inner side of the filter screen 102, ensuring sufficient contact between the desulfurizer solution and the exhaust gas, and ensuring that the exhaust gas and the desulfurizer are easily and evenly mixed, thereby improving the subsequent desulfurization treatment effect.

[0041] Under the action of continuous blowing, the gas treated by the spray tower 2 reaches the secondary treatment box 3 and enters the interior of the filter box 11. The inner gas is squeezed and will pass through the dust filter 112, the deodorizing filter 113, the activated carbon filter 114 and the air filter element 115 in turn, and finally be discharged to the outside through the air outlet 116 at one end of the filter box 11. The dust filter 112, the deodorizing filter 113, the activated carbon filter 114 and the air filter element 115 can fully purify the impurities and odors in the gas. After long-term use, the secondary treatment box 3 can be opened, the filter box 11 can be removed by the pulley at the bottom of the filter box 11, and the dust filter 112, the deodorizing filter 113, the activated carbon filter 114 and the air filter element 115 can be replaced, which is more convenient to use.
