Description

Technical Field

[0001] This invention relates to the field of environmental engineering technology, and in particular to an atmospheric desulfurization device for environmental engineering. Background Technology

[0002] With the acceleration of industrialization, flue gas emitted from coal-fired power plants, metallurgy, chemical industries, and other sectors contains large amounts of sulfur dioxide (SO2). If left untreated, this will lead to environmental problems such as acid rain and smog, seriously harming the ecological environment and human health. Therefore, flue gas desulfurization technology has become an important part of environmental protection projects and is widely used in the field of air pollution control.

[0003] Traditional wet desulfurization technologies (such as the limestone-gypsum method) achieve efficient SO2 removal by reacting sulfur-containing flue gas with an alkaline slurry (such as limestone slurry) to generate calcium sulfite, which is then further oxidized into gypsum.

[0004] However, existing desulfurization units still have the following problems in actual operation: Insufficient flue gas pretreatment: Flue gas often contains impurities such as dust and particulate matter. If it enters the desulfurization tower directly, it can easily lead to clogging of the spray layer and slurry contamination, reducing desulfurization efficiency and increasing equipment maintenance costs. Uneven mixing of lime slurry: Traditional stirring methods may lead to uneven mixing of lime powder and water, affecting the reactivity of the slurry and thus reducing the SO2 absorption efficiency. Difficulty in gypsum deposition and cleaning: The gypsum generated by the reaction is easy to deposit at the bottom of the desulfurization tower. If it is not cleaned in time, it may block the discharge port and affect the continuous operation of the equipment. Manual cleaning is labor-intensive and poses safety hazards. Insufficient contact between gas and slurry: The gas-liquid mixing efficiency in some desulfurization towers is low, resulting in SO2 not being fully absorbed and discharged, affecting the desulfurization effect and making it difficult to meet increasingly stringent environmental emission standards. Inconvenient filter replacement: Existing filter devices usually use fixed filters, which are easily clogged by dust after long-term operation. Cleaning or replacement requires stopping the machine for disassembly, affecting production efficiency. Summary of the Invention

[0005] The purpose of this invention is to solve the problem of insufficient flue gas pretreatment in the prior art: flue gas often contains impurities such as dust and particulate matter. If it enters the desulfurization tower directly, it will easily lead to clogging of the spray layer and slurry contamination, reduce desulfurization efficiency, and increase equipment maintenance costs. Existing filtration devices usually use fixed filter screens, which are easily clogged by dust after long-term operation. Cleaning or replacement requires stopping the machine for disassembly, which affects production efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an atmospheric desulfurization device for environmental protection engineering, comprising: a base plate, a support mechanism fixedly installed on the top of the base plate, a desulfurization tower fixedly installed on the top of the support mechanism, a fan fixedly installed on one side of the base plate, a straight pipe fixedly installed at one end of the fan, an air inlet pipe fixedly embedded on the outer surface of the straight pipe, a filter box fixedly installed at one end of the straight pipe, a long pipe fixedly embedded on one side of the filter box, the long pipe being fixedly embedded inside the desulfurization tower, and multiple threaded clamps movably embedded in the inner wall of the filter box.

[0007] The technical effect of adopting the above-mentioned further solution is as follows: First, the fan is started by an external power source, and the gas enters the inside of the straight pipe from the inlet pipe. Under the blowing of the fan, the gas inside the straight pipe quickly enters the inside of the desulfurization tower. At this time, when the gas passes through the filter box, the filter box is equipped with a filter screen to filter the gas, which can reduce the large impurities inside the gas.

[0008] In a preferred embodiment, two sliding grooves are formed on both sides of the inner wall of the filter box, and filter screens are slidably connected inside the multiple sliding grooves. Multiple threaded rods are movably embedded inside the filter screens. A recycling box is slidably connected inside the support mechanism. Two baffles are fixedly installed on the inner wall of the recycling box. A storage plate is detachably connected to the top of the two baffles. A support plate is fixedly installed on the top of the desulfurization tower, and a mixing tank is fixedly installed on the top of the support plate.

[0009] The technical advantage of the above-mentioned further solution is that by rotating the threaded clamp to disengage from the holes on the filter screen surface, the filter screen can be removed and replaced, preventing it from becoming unusable or clogged. After pulling the collection box out from the support mechanism, the storage plate can be lifted from the surface of the baffle to remove the lime paste on its surface. By rotating the threaded clamp to disengage from the holes on the filter screen surface, the filter screen can be removed from the filter box and replaced, preventing excessive buildup on the filter screen surface that could lead to clogging and unusability.

[0010] In a preferred embodiment, a motor is fixedly installed on the top of the mixing tank, a stirring rod is fixedly installed on the output end of the motor, a plurality of stirring blades are fixedly installed on the outer surface of the stirring rod, a rotating disk is fixedly installed on the bottom end of the stirring rod, a discharge hole is opened at the bottom of the rotating disk, the discharge hole rotates on the top of the support disk, and a discharge pipe is fixedly embedded at the bottom of the support disk.

[0011] The technical effect of adopting the above-mentioned further solution is that the motor is started by an external power source, and the motor drives the stirring rod to rotate. At this time, the stirring rod drives the stirring blade to rotate, and the lime powder is poured into the inside of the mixing tank for mixing and blending, making the lime slurry more uniform.

[0012] In a preferred embodiment, a material storage mechanism is fixedly installed on the top of the desulfurization tower, the discharge pipe is fixedly embedded inside the material storage mechanism, a rotating rod is rotatably connected to the inner wall of the desulfurization tower, and a rotating plate is fixedly installed on the outer surface of the rotating rod.

[0013] The technical effect of adopting the above-mentioned further solution is that after stirring, the stirring rod drives the bottom rotating disk to rotate. At this time, the rotating disk rotates once and drives the discharge hole to rotate once. When the discharge hole rotates to be directly above the discharge pipe, the lime slurry inside will intermittently enter the storage mechanism through the discharge pipe, so that the storage mechanism will not be blocked or filled.

[0014] In a preferred embodiment, multiple spray heads are fixedly installed on the top of the inner wall of the base plate, the rotating rod is fixedly installed at the bottom end of the stirring rod, an air outlet pipe is fixedly embedded on the outer surface of the desulfurization tower, a one-way valve is installed inside the air outlet pipe, and multiple water outlet holes are opened on the outer surface of the storage plate.

[0015] The technical effect of adopting the above-mentioned further solution is as follows: the flue gas enters the interior of the desulfurization tower and comes into countercurrent contact with the limestone slurry. It is absorbed by the slurry and generates calcium sulfite, which is further oxidized into gypsum. The gypsum falls onto the surface of the storage plate due to gravity. At the same time, when the stirring rod rotates, it drives the rotating rod to rotate. At this time, the rotating rod drives the rotating plate to rotate inside the desulfurization tower, which makes the fusion efficiency of flue gas and limestone slurry higher. A small amount of slurry will flow into the interior of the recovery box through the water outlet hole. The treated gas is discharged to the outside through the gas outlet pipe.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0017] 1. In this embodiment of the invention, the blower is first started by an external power source. Gas enters the straight pipe from the inlet pipe. Under the blowing of the blower, the gas inside the straight pipe quickly enters the desulfurization tower. At this time, when the gas passes through the filter box, the filter box is equipped with a filter screen to filter the gas, which can reduce the large impurities in the gas. At the same time, the gas enters the desulfurization tower through the long pipe. Simultaneously, the motor is started by an external power source. The motor drives the stirring rod to rotate. At this time, the stirring rod drives the stirring blade to rotate, and the lime powder is poured into the mixing tank for mixing. After mixing, the stirring rod drives the rotating disk at the bottom to rotate. At this time, each rotation of the rotating disk will drive the discharge hole to rotate once. When the discharge hole rotates to be directly above the discharge pipe, the lime slurry inside will intermittently enter the storage mechanism through the discharge pipe, so that the storage mechanism will not be blocked or filled.

[0018] 2. In this embodiment of the invention, after the recycling box is pulled out from the inside of the support mechanism, the storage plate can be lifted from the surface of the baffle, and the lime paste on its upper surface can be removed. By rotating the threaded clamp, it can be disassembled from the hole on the surface of the filter screen. At this time, the filter screen can be removed from the inside of the filter box. After disassembly, it can be replaced to prevent excessive accumulation on the surface of the filter screen, which may cause blockage and render it unusable.

[0019] 3. In this embodiment of the invention, flue gas enters the interior of the desulfurization tower and comes into countercurrent contact with limestone slurry. It is absorbed by the slurry to generate calcium sulfite, which is further oxidized into gypsum. The gypsum falls onto the surface of the storage plate due to gravity. At the same time, when the stirring rod rotates, it drives the rotating rod to rotate. At this time, the rotating rod drives the rotating plate to rotate inside the desulfurization tower, which makes the fusion efficiency of flue gas and limestone slurry higher. A small amount of slurry will flow into the interior of the recovery box through the water outlet. The treated gas is discharged to the outside through the gas outlet pipe. Rotating the one-way valve makes the gas outlet pipe in the closed and open state. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1 to 9 This embodiment provides a technical solution: an atmospheric desulfurization device for environmental protection engineering, comprising: a base plate 101, a support mechanism 115 fixedly installed on the top of the base plate 101, a desulfurization tower 102 fixedly installed on the top of the support mechanism 115, a fan 120 fixedly installed on one side of the base plate 101, a straight pipe 121 fixedly installed at one end of the fan 120, an air inlet pipe 122 fixedly embedded on the outer surface of the straight pipe 121, a filter box 123 fixedly installed at one end of the straight pipe 121, a long pipe 126 fixedly embedded on one side of the filter box 123, the long pipe 126 fixedly embedded inside the desulfurization tower 102, and a plurality of threaded clamps 125 movably embedded in the inner wall of the filter box 123.

[0033] In use, the blower 120 is first started by an external power source. The gas enters the straight pipe 121 from the inlet pipe 122. Under the blowing of the blower 120, the gas inside the straight pipe 121 quickly enters the desulfurization tower 102. When the gas passes through the filter box 123, the filter screen 124 inside the filter box 123 can filter the gas, thereby reducing larger impurities in the gas.

[0034] like Figures 1 to 9As shown, in one embodiment, two sliding grooves 1231 are opened on both sides of the inner wall of the filter box 123. Filter screens 124 are slidably connected inside the multiple sliding grooves 1231. Multiple threaded clamps 125 are movably embedded inside the filter screens 124. A recovery box 116 is slidably connected inside the support mechanism 115. Two baffles 119 are fixedly installed on the inner wall of the recovery box 116. A storage plate 117 is detachably connected to the top of the two baffles 119. A support plate 109 is fixedly installed on the top of the desulfurization tower 102. A mixing tank 103 is fixedly installed on the top of the support plate 109. By rotating the threaded clamps 125, the filter screen 124 can be disassembled from the holes on the surface of the filter screen 124 for replacement to prevent it from becoming unusable or clogged. After pulling the recovery box 116 out of the support mechanism 115, the storage plate 117 can be lifted from the surface of the baffles 119 to remove the lime paste on its upper surface. By rotating the threaded lever 125, the filter screen 124 can be disassembled from the hole on the surface of the filter screen 124. At this time, the filter screen 124 can be removed from the inside of the filter box 123. After disassembly, it can be replaced to prevent excessive accumulation on the surface of the filter screen 124, which may cause blockage and render it unusable.

[0035] like Figures 1 to 9 As shown, in one embodiment, a motor 104 is fixedly installed on the top of the mixing tank 103, a stirring rod 105 is fixedly installed on the output end of the motor 104, a plurality of stirring blades 106 are fixedly installed on the outer surface of the stirring rod 105, a rotating disk 107 is fixedly installed on the bottom end of the stirring rod 105, a discharge hole 108 is opened at the bottom of the rotating disk 107, the discharge hole 108 rotates on the top of the support disk 109, and a discharge pipe 110 is fixedly embedded at the bottom of the support disk 109. The motor 104 is started by an external power source, and the motor 104 drives the stirring rod 105 to rotate. At this time, the stirring rod 105 drives the stirring blades 106 to rotate, and the lime powder is poured into the interior of the mixing tank 103 for mixing and blending, so that the lime slurry is more uniform.

[0036] like Figures 1 to 9 As shown, in one embodiment, a storage mechanism 111 is fixedly installed on the top of the desulfurization tower 102, and a discharge pipe 110 is fixedly embedded inside the storage mechanism 111. A rotating rod 128 is rotatably connected to the inner wall of the desulfurization tower 102, and a rotating plate 112 is fixedly installed on the outer surface of the rotating rod 128. After stirring, the stirring rod 105 drives the rotating disk 107 at the bottom to rotate. At this time, the rotating disk 107 will drive the discharge hole 108 to rotate once for each rotation. When the discharge hole 108 rotates to be directly above the discharge pipe 110, the lime slurry inside it will intermittently enter the storage mechanism 111 through the discharge pipe 110, so that the storage mechanism 111 will not be blocked or filled.

[0037] like Figures 1 to 9As shown, in one embodiment, multiple spray heads 127 are fixedly installed on the top of the inner wall of the base plate 101, a rotating rod 128 is fixedly installed at the bottom end of the stirring rod 105, an exhaust pipe 113 is fixedly embedded on the outer surface of the desulfurization tower 102, a one-way valve 114 is provided inside the exhaust pipe 113, and multiple water outlet holes 118 are opened on the outer surface of the storage plate 117. Flue gas enters the interior of the desulfurization tower 102 and comes into countercurrent contact with limestone slurry. It is absorbed by the slurry and generates calcium sulfite, which is further oxidized into gypsum. The gypsum falls onto the surface of the storage plate 117 due to gravity. At the same time, when the stirring rod 105 rotates, it drives the rotating rod 128 to rotate. At this time, the rotating rod 128 drives the rotating plate 112 to rotate inside the desulfurization tower 102, which makes the efficiency of flue gas and limestone slurry fusion higher. A small amount of slurry will flow into the interior of the recovery box 116 through the water outlet hole 118. The treated gas is discharged to the outside through the exhaust pipe 113.

[0038] Working Principle: During operation, the blower 120 is first started by an external power source. Gas enters the straight pipe 121 through the inlet pipe 122. Driven by the blower 120, the gas in the straight pipe 121 quickly enters the desulfurization tower 102. As the gas passes through the filter box 123, which contains a filter screen 124, it is filtered, reducing larger impurities. Simultaneously, the gas enters the desulfurization tower 102 through the long pipe 126. At the same time, the motor 104 is started by an external power source, driving the stirring rod 105 to rotate. The stirring rod 105 then drives the stirring blades 106 to rotate, adding lime powder into the mixing tank 103 for mixing. After mixing, the stirring rod 105 drives the rotating disc 107 at the bottom to rotate. Each rotation of the rotating disc 107 causes the discharge hole 108 to rotate once. When the discharge hole 108 is directly above the discharge pipe 110, the lime powder inside... The mortar will intermittently enter the storage mechanism 111 through the discharge pipe 110, so that the storage mechanism 111 will not be blocked or filled. The flue gas enters the desulfurization tower 102 and comes into countercurrent contact with the limestone slurry. It is absorbed by the slurry and generates calcium sulfite, which is further oxidized into gypsum. The gypsum falls onto the surface of the storage plate 117 due to gravity. At the same time, when the stirring rod 105 rotates, it drives the rotating rod 128 to rotate. At this time, the rotating rod 128 drives the rotating plate 112 to rotate inside the desulfurization tower 102, so that the flue gas and lime slurry are more efficiently mixed. A small amount of slurry will flow into the recovery box 116 through the water outlet 118. The treated gas is discharged to the outside through the gas outlet pipe 113. Turning the one-way valve 114 makes the gas outlet pipe 113 in a closed and open state. After pulling the recovery box 116 out of the support mechanism 115, the storage plate 117 can be lifted from the surface of the baffle 119 and the lime gypsum on its surface can be removed. By rotating the threaded lever 125, the filter screen 124 can be disassembled from the hole on its surface. At this time, the filter screen 124 can be removed from the inside of the filter box 123. After disassembly, it can be replaced to prevent excessive accumulation on the surface of the filter screen 124, which may cause blockage and render it unusable.
