Description

Technical Field

[0001] The invention relates to the technical field of tail gas treatment equipment, and more specifically to a dust collecting chamber for tail gas of drying compound fertilizer. Background Art

[0002] In the production process of monoammonium phosphate, diammonium phosphate, and compound fertilizer in fertilizer enterprises, natural gas combustion is used to generate hot air, which enters the phosphate fertilizer product dryer to dry the newly produced products and take away the evaporated water to form the so-called tail gas, which is discharged to the back stage for tail gas treatment. However, the tail gas contains a large amount of powdered fertilizer and cannot be discharged directly. According to national environmental protection requirements, PM2.5 and other particles in the exhaust gas must meet the standards before they can be discharged, so the subsequent treatment is also quite complicated. The back stage dust removal includes dust collection chamber dust removal, bag dust removal and electrostatic dust removal processes.

[0003] At present, most commonly used exhaust dust collection chambers require manual replacement of the filter device, and manual replacement often requires the equipment to be stopped to ensure the safety of the operator.

[0020] Specifically, when the staff starts the device, the motor 5 will drive the connecting rod 205 to rotate, and the rotation of the connecting rod 205 will drive the blades 206 to rotate synchronously, so that the exhaust gas entering the outer shell 203 through the connecting port 209 can flow fully, and at the same time, the water inlet 4 will pour cooling water into the water tank 204, and then spray it out from the water nozzle 210, so that the exhaust gas in the outer shell 203 can be fully in contact with the cooling water during the flow, thereby reducing the solid particles in the exhaust gas, and the deflection between each group of blades 206 is inconsistent, so that part of the exhaust gas can continuously float up and down under the action of the blades 206, increasing the floating time of the exhaust gas, when the exhaust gas contacts the cooling water, the temperature of the exhaust gas will decrease, and then the exhaust gas will float downward, so that it can flow to the drying chamber 3 through the connecting pipe 8, and the cooling water that absorbs the solid particles and heat in the exhaust gas will flow to the filter 208, and then flow to the dust collector 118 through the drain port 207.

[0022] See also Figure 6 , Figure 7 and Figure 8The end of the rotating disk 104 away from the gear 102 is fixedly connected to a connecting rod 105, and the end of the connecting rod 105 away from the rotating disk 104 is rotatably connected to a filter plate 109, and the filter plate 109 is fixedly connected to the housing 101. The outer side of the connecting rod 105 is fixedly connected to a partition 106, and both sides of the partition 106 are provided with a rotating rod 112, and the rotating rod 112 is provided with a spline. The rotating rod 112 is located above the filter plate 109 and the rotating rod 112 passes through the rotating disk 104. The rotating rod 112 is far away from the rotating disk 104. A magnet 103 is fixedly connected to one end away from the filter plate 109, and the magnet 103 is movably connected to the rotating disk 104. A threaded rod 115 is fixedly connected to one end of the rotating rod 112 away from the rotating disk 104. The outer side of the threaded rod 115 is threadedly connected to a limiting block 114. The outer side of the rotating rod 112 is movably connected to a connecting rod 107. A plurality of filter blocks 113 are arranged on the outer side of the connecting rod 107. The filter blocks 113 are all on the half side of the connecting rod 107. The filter blocks 113 are made of soft material and are provided with a filter net inside.

[0023] Specifically, the motor 5 drives the connecting rod 1 205 to rotate and drives the gear 2 201 to rotate synchronously. The rotation of the gear 201 drives the gear 102 to rotate synchronously through the belt 111, and the magnet under the gear 102 is attracted to the magnet 103, so that the rotation of the gear 102 drives the magnet 103 to rotate synchronously, thereby driving the filter block 113 on the connecting rod 107 to rotate synchronously, fanning the exhaust gas while fully contacting the exhaust gas, and the filter block 113 will continuously contact the fixed rod 108 while rotating. The beating of the filter block 113 on the fixed rod 108 can effectively reduce the occurrence of solid particles in the exhaust gas adhering to the filter block 113, and the exhaust gas entering the housing 101 through the air inlet 7 will be heated due to the effect of heat.

When the filter block 113 needs to be replaced, the motor 116 is started, and the motor 116 controls the rotating disk 104 to rotate, thereby disconnecting the magnet 103 and the gear 102. When the motor 116 rotates 180 degrees and stops rotating, the new magnet 103 will automatically be attracted to the magnet on the gear 102 under the action of magnetic force, thereby driving the new filter block 113 to perform filtering, and the staff can replace and clean the connecting rod 107 by screwing the limit block 114.

[0024] See also Fig. 9 and Fig.10A slide plate 117 is fixedly connected to the side of the housing 101 away from the motor 5, and a dust collector 118 is fixedly connected to the inside of the slide plate 117.

A dust exhaust pipe 120 is arranged on the inner side of the control switch 119. By arranging the slide plate 117, solid particles in the exhaust gas can fall into the dust collector 118 after passing through the filter plate 109, thereby reducing adhesion to the surface of the slide plate 117.

[0025] See also Fig.10 , Fig.11 and Fig.12 The dust collector 118 includes a protective shell 123 fixedly connected to the slide plate 117, the end of the protective shell 123 away from the shell 101 is rotatably connected to a rotating block 125, the rotating block 125 is located at the center of the protective shell 123, a plurality of scrapers 127 are fixedly connected to the outer side of the rotating block 125, the end of the rotating block 125 away from the shell 101 is rotatably connected to a fixed block 126, a plurality of openings are provided on the fixed block 126, a partition 124 is fixedly connected to the end of the fixed block 126 away from the rotating block 125, the partition 124 is inclined, the partition 124 is slidably connected to the scraper 127 and the partition 124 is fixedly connected to the protective shell 123, the center of the partition 124 is fixedly connected to the dust exhaust pipe 120, the outer side of the protective shell 123 is respectively provided with a water inlet pipe 122 and a drain pipe 121, the water inlet pipe 122 and the drain pipe 121 are both located at the lower end of the partition 124.

[0026] Specifically, the filter block 113 will adsorb the solid particles in the exhaust gas after contacting with the exhaust gas, and after beating the fixed rod 108, the solid particles can pass through the filter plate 109 and fall into the dust collector 118. When the staff needs to recover the solid particles in the dust collector 118, the control switch 119 is started, and the control switch 119 will control the rotating block 125 to rotate. The rotation of the rotating block 125 will drive the scraper 127 to rotate, and then the scraper 127 can scrape the partition 124, so that the solid particles can flow out through the opening on the fixed block 126 to the dust exhaust pipe 120 for discharge, and the cooling water that absorbs the heat of the exhaust gas in the cooling chamber 2 will enter between the partition 124 and the protective shell 123 through the water inlet pipe 122 and then be discharged from the drain pipe 121. When flowing in the partition 124, the solid particles can be heated, so that the solid particles on the partition 124 can be in a dry state, thereby reducing the adhesion of the solid particles.

[0027] See also Fig.13 and Fig.14The drying chamber 3 includes a shell 307 fixedly connected to the cooling chamber 2, a heater 310 is fixedly connected to the inside of the shell 307, a heating block 309 is fixedly connected to the center of the heater 310, a spiral tube 311 is arranged on the outside of the heating block 309, one end of the spiral tube 311 is fixedly connected to the connecting pipe 8, a conical plate 308 is arranged above the heating block 309, the conical plate 308 is fixedly connected to the shell 307, a connecting block 303 is fixedly connected to the shell 307, the connecting block 303 is fixedly connected to the exhaust port 6, a connecting plate 306 is fixedly connected to the lower end of the connecting block 303, and the connecting plate 306 is fixedly connected to the shell 307.

[0028] See also Fig.13 and Fig.14 The center of the connecting disk 306 is rotatably connected with a connecting rod 1 304, and the outer side of the connecting rod 1 304 is fixedly connected with two sets of turntables 305, the turntable 305 is composed of an alternating combination of filter plates and baffle plates, and the filter plates and baffle plates on the two turntables 305 do not overlap, the turntable 305 passes through the exhaust port 6 and is slidably connected to the exhaust port 6, and the end of the connecting rod 1 304 away from the turntable 305 is fixedly connected with a gear 4 301, and the outer side of the gear 4 301 is transmission-connected with a belt 2 302, and the belt 2 302 is transmission-connected with the gear 3 202, and the sliding connection between the turntable 305 and the exhaust port 6 allows the dried exhaust gas to be filtered once through the turntable 305 from the exhaust port 6 and then discharged, and the turntable 305 is driven to rotate by the connecting rod 1 304, which can effectively avoid the phenomenon of poor filtering effect caused by excessive use of the same filter plate.

[0029] Specifically, the exhaust gas after being cooled will move downward, and then flow into the spiral tube 311 through the connecting pipe 8. While the exhaust gas is flowing in the spiral tube 311, the heater 310 will heat the heating block 309 so that the heating block 309 can dry the exhaust gas in the spiral tube 311 by transmission. After being dried, the exhaust gas will move upward, and then flow out of the spiral tube 311, and then enter the exhaust port 6 from the conical plate 308. Since the environment of the conical plate 308 is relatively large, the molecules of the exhaust gas will be more dispersed after entering the conical plate 308, so that the exhaust gas that has not passed through the conical plate 308 will be dried. The fully heated exhaust gas can stay at the conical plate 308 to continue to be heated, while the dry exhaust gas will enter the exhaust port 6. After the exhaust gas enters the exhaust port 6, the rotation of the connecting rod 1 205 will drive the gear 3 202 to rotate synchronously, so that the gear 3 202 can drive the gear 4 301 to rotate through the belt 2 302, and then the turntable 305 can rotate around the connecting rod 1 304, so that the filter plates on the two layers of the turntable 305 can alternately contact the exhaust port 6, so that the dried exhaust gas can be filtered again through the turntable 305 and then discharged.

[0030] Working principle of the present invention: when the staff starts the device, the exhaust gas will enter the dust removal chamber 1 from the air inlet 7, and the start of the motor 5 will drive the connecting rod 1 205 to rotate. The motor 5 drives the connecting rod 1 205 to rotate and drives the gear 2 201 to rotate synchronously. The rotation of the gear 201 will drive the gear 102 to rotate synchronously through the belt 111, and the magnet under the gear 102 will be attracted by the magnet 103, so that the rotation of the gear 102 will drive the magnet 103 to rotate synchronously, and then drive the filter block 113 on the connecting rod 107 to rotate synchronously, fanning the exhaust gas while fully contacting with the exhaust gas, and the filter block 113 will continuously contact with the fixed rod 108 while rotating, through the filter block 11 The beating of the fixing rod 108 can effectively reduce the solid particles in the exhaust gas from adhering to the filter block 113. The exhaust gas entering the housing 101 through the air inlet 7 will move upward due to the effect of heat, and will be cooled to a certain extent after being filtered by the filter block 113, so that part of the exhaust gas will reciprocate up and down in the filter block 113, and the exhaust gas filtered by the filter block 113 will enter the cooling chamber 2 through the connecting port 209. When the filter block 113 needs to be replaced, the motor 116 is started, and the motor 116 controls the rotating disk 104 to rotate, thereby disconnecting the magnet 103 and the gear 102. When the motor 116 rotates 180 degrees, it stops rotating. Under the action of magnetic force, the new magnet 103 will automatically attract the magnet on the gear 102, thereby driving the new filter block 113 to perform filtering, and the staff can replace and clean the connecting rod 107 by screwing the limit block 114, and the filter block 113 will adsorb the solid particles in the exhaust gas after contacting with the exhaust gas, and after beating the fixed rod 108, the solid particles can pass through the filter plate 109 and fall into the dust collector 118. When the staff needs to recycle the solid particles in the dust collector 118, the control switch 119 is started, and the control switch 119 will control the rotating block 125 to rotate, and the rotation of the rotating block 125 will drive the scraper 127 to rotate, and the partition can be reclaimed by the scraper 127. The first baffle 124 is scraped to allow the solid particles to flow out through the opening on the fixed block 126 to the dust exhaust pipe 120 for discharge, and the cooling water that absorbs the heat of the exhaust gas in the cooling chamber 2 will enter between the baffle 124 and the protective shell 123 through the water inlet pipe 122 and be discharged from the drain pipe 121. When flowing in the baffle 124, the solid particles can be heated, so that the solid particles on the baffle 124 can be in a dry state, reducing the adhesion of the solid particles, and the rotation of the connecting rod 1 205 will drive the blades 206 to rotate synchronously, so that the exhaust gas entering the shell 2 203 through the connecting port 209 can flow fully, and at the same time, the water inlet 4 will pour the cooling water into the water tank 204, and then spray it out from the water spray port 210.The exhaust gas from the second shell 203 can fully contact with the cooling water when flowing, thereby reducing the solid particles in the exhaust gas, and the deflection between each group of blades 206 is inconsistent, so that part of the exhaust gas can continuously float up and down under the action of the blades 206, increasing the floating time of the exhaust gas. When the exhaust gas contacts the cooling water, the temperature of the exhaust gas will decrease, thereby causing the exhaust gas to float downward, so that it can flow into the drying chamber 3 through the connecting pipe 8, and the cooling water that absorbs the solid particles and heat in the exhaust gas will flow into the filter screen 208, and then flow into the dust collector 118 through the drain port 207. At the same time, the exhaust gas after cooling will move downward, and then flow into the spiral tube 311 through the connecting pipe 8. When the exhaust gas flows in the spiral tube 311, the heater 310 will heat the heating block 309 so that the heating block 309 can heat the spiral tube 311 by transmission. The tail gas in the exhaust port 6 is dried. After drying, the tail gas moves upward and then flows out of the spiral tube 311, and then enters the exhaust port 6 from the conical plate 308. Since the environment of the conical plate 308 is relatively large, the molecules of the tail gas will be relatively dispersed after entering the conical plate 308, so that the tail gas that has not been fully heated can stay at the conical plate 308 to continue to be heated, and the dry tail gas will enter the exhaust port 6. After the tail gas enters the exhaust port 6, the rotation of the connecting rod 1 205 will drive the gear 3 202 to rotate synchronously, so that the gear 3 202 can drive the gear 4 301 to rotate through the belt 2 302, and then the turntable 305 can rotate around the connecting rod 1 304, so that the filter plates on the two layers of the turntable 305 can alternately contact the exhaust port 6, so that the dried tail gas can be filtered again through the turntable 305 and then discharged.
