This requires a spraying device for secondary treatment. However, the spraying amount of the spraying device is fixed and cannot be adjusted according to the discharge amount of the tail gas, which will cause excessive water mist and unnecessary consumption, and too little water mist will affect the efficiency of tail gas treatment.

Detailed implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] The present invention provides an adjustable pyrometallurgical precious metal refining spraying device as Figures 1-6 shown, including: Gas treatment box body 100; Smelting furnace 200, and the harmful gases generated during the smelting process of the smelting furnace 200 are transported to the inside of the gas treatment box body 100; Spraying assembly 300, which is installed inside the gas treatment box body 100 and is used to spray liquid (such as water or chemical reagent) on the harmful gases; Knocking assembly 400, which is installed inside the gas treatment box body 100 and drives the spraying assembly 300 to open the spray when rotating; Fan 500, which is installed at the exhaust port of the gas treatment box body 100 and is driven to rotate when exhausting; First pulley 600, which is coaxially fixed with the fan 500 and drives the knocking assembly 400 to rotate when the fan 500 rotates; Filtering device 700, which is installed between the spraying assembly 300 and the gas treatment box body 100; An exhaust passage 110 is fixedly installed at the top of the gas treatment box body 100, and the exhaust passage 110 is sleeved outside the fan 500 and the first pulley 600. A pressure valve 120 is installed on the exhaust passage 110, and the pressure valve 120 is located below the fan 500. A positioning frame plate 140 for supporting the fan 500 and the first pulley 600 is installed inside the exhaust passage 110.

[0024] Among them, sufficient liquid is added to the inside of the gas treatment box body 100, and the water pump is started. Under the action of the water pump, the liquid relies on the pipeline to pass through the filtering device 700 and is transported to the inside of the spraying assembly 300, and is sprayed out through the spraying assembly 300. When the gas enters the inside of the gas treatment box body 100, it enters the liquid, and then passes through the liquid into the upper half of the gas treatment box body 100, and contacts and condenses with the liquid sprayed out by the spraying assembly 300, and the pressure inside the gas treatment box body 100 is increased, so that the pressure valve 120 is opened, and the gas is discharged through the exhaust passage 110. When discharging, it pushes the fan 500 to rotate, so that the fan 500 drives the first pulley 600 to rotate, and the first pulley 600 drives the knocking assembly 400 to push the spraying assembly 300, so that the spraying assembly 300 is opened, and the faster the rotation speed of the fan 500, the greater the spraying amount of the spraying assembly 300, and vice versa.

[0025] Among them, through the setting of the fan 500, it rotates under the push when the gas is discharged, and cooperates with the first pulley 600 when rotating, so that the first pulley 600 rotates, and drives the knocking assembly 400 when rotating, so that the knocking assembly 400 pushes the spraying assembly 300, so that the spraying assembly 300 is opened. At the same time, the opening degree of the spraying assembly 300 is proportional to the discharge range of the gas.

[0026] Relying on the setting of the exhaust passage 110 to ensure the normal installation of the pressure valve 120, and at the same time ensure the stability of the fan 500, so that the gas can normally push the fan 500 to rotate when discharging.

[0027] Relying on the setting of the positioning frame plate 140 to ensure the normal installation of the fan 500 and the first pulley 600, and avoid the deviation of the first pulley 600 and the fan 500 under the action of external force.

[0028] In some embodiments of the present invention, the spraying assembly 300 includes: A housing 310, and the housing 310 is detachably fixed inside the gas treatment box body 100; A sealing plate 320, the sealing plate 320 is rotatably installed inside the housing 310. Sealing gaskets are arranged around the sealing plate 320, and are hermetically arranged with the housing 310 to prevent liquid from discharging from the distance-limiting through hole 312. A force-bearing plate 340, and the force-bearing plate 340 extends to the outside of the housing 310 The power storage component 330 includes: A blocking plate 331, wherein the blocking plate 331 is fixed to the outer side of the housing 310; A spring 332, the spring 332 is fixed on the blocking plate 331 and contacts one side of the force-bearing plate 340; A plurality of atomizing nozzles 311 in a circular array are fixedly mounted on the bottom of the housing 310. The housing 310 is provided with a distance limiting through hole 312 for the force-bearing plate 340 to pass through, so as to allow the force-bearing plate 340 to pass through and limit its range of motion; The sealing plate 320 is provided with a plurality of flow guide holes 321 in a circular array, and the flow guide holes 321 correspond to the atomizing nozzle 311. When the flow guide holes 321 are misaligned with the atomizing nozzle 311, the liquid flow is blocked and the spraying stops. The other side of the force-bearing plate 340 is bonded with an air bag 322 in contact with the extrusion head 410, which can buffer the impact force and protect the force-bearing plate 340 and the sealing plate 320 from damage.

[0029] Among them, when the force-bearing plate 340 is squeezed by the knocking assembly 400, it will drive the sealing plate 320 to rotate, so that the guide hole 321 on the sealing plate 320 corresponds to the atomizing nozzle 311, and the liquid will enter the interior of the atomizing nozzle 311 through the guide hole 321 and be sprayed out through the atomizing nozzle 311. At the same time, when the force-bearing plate 340 rotates, the spring 332 will be squeezed to compress and accumulate force. After the force-bearing plate 340 is offset by the knocking assembly 400, the elastic force of the spring 332 will be released, so that the spring 332 pushes the force-bearing plate 340 and the sealing plate 320 to rotate and reset.

[0030] The setting of the shell 310 ensures the normal installation and use of the blocking plate 320 and the atomizing nozzle 311, and at the same time ensures that the shell 310 will not be deflected under the action of external force.

[0031] The blocking plate 331 is arranged to ensure the normal installation and fixation of the spring 332, and the spring 332 can store force normally when it is under pressure. At the same time, when the force plate 340 and the knocking assembly 400 are offset, the elastic force of the spring 332 will be released, and the blocking plate 320 will be pushed to rotate and reset, and the atomizing nozzle 311 will be blocked.

[0032] The provision of the airbag 322 can reduce the collision force between the force-bearing plate 340 and the striking assembly 400, thereby preventing the force-bearing plate 340 and the striking assembly 400 from breaking after long-term use.

[0033] In some embodiments of the present invention, the striking assembly 400 includes: The extrusion head 410 squeezes the force-bearing plate 340 when rotating, so that the force-bearing plate 340 drives the blocking plate 320 to rotate and adjust to a spraying state; A rotating shaft 420, which is rotatably mounted inside the gas processing box 100, extends upward to the outside of the gas processing box 100, and is fixedly connected to the extrusion head 410; A second pulley 430, the second pulley 430 is fixed to the outside of the rotating shaft 420 and is drivingly connected to the first pulley 600; A receiving plate 130 for supporting the rotating shaft 420 is fixedly installed inside the gas processing box 100 .

[0034] When the first pulley 600 rotates, the second pulley 430 will be driven to rotate through the belt, so that the second pulley 430 drives the rotating shaft 420 to rotate, and the rotating shaft 420 drives the extrusion head 410 to rotate. When the extrusion head 410 rotates, it will contact the force plate 340 and squeeze the force plate 340 to rotate. After the force plate 340 rotates a certain angle, the force plate 340 will be staggered with the extrusion head 410.

[0035] Among them, the spraying amount of the spray component 300 is adjusted according to the gas discharge speed through the coordinated setting of the force plate 340 and the extrusion head 410, so that the spraying amount of the spray component 300 is adjusted according to the exhaust gas discharge amount, avoiding too little water mist at the spraying point affecting the efficiency of exhaust gas treatment, and too much water mist sprayed causing unnecessary consumption.

[0036] The setting of the rotating shaft 420 ensures the normal installation and use of the second pulley 430 and the extrusion head 410, and enables the second pulley 430 to drive the extrusion head 410 to rotate normally, so that the extrusion head 410 is released from the force plate 340, and the force plate 340 is pushed to rotate, and the contact position components are reduced during rotation.

[0037] The receiving plate 130 is used to support the rotating shaft 420 and ensure the stability of the rotating shaft 420 when it rotates under force.

[0038] In some embodiments of the present invention, the filtering device 700 comprises: Filter housing 710; A filter screen 720, the filter screen 720 is detachably fixed inside the filter housing 710; An activated carbon plate 730 , which is detachably fixed inside the filter housing 710 and located above the filter screen 720 ; The filter housing 710 , the gas processing box 100 and the housing 310 are connected via a water conduit 800 .

[0039] The filter housing 710 is provided to ensure that the filter screen 720 and the activated carbon plate 730 are properly installed and fixed. The filter screen 720 and the activated carbon plate 730 are arranged in coordination to filter the flowing liquid and avoid clogging of the atomizing nozzle 311 .

[0040] Working method of the present invention: Sufficient liquid is added to the interior of the gas treatment box 100, and the tail gas generated by the smelting furnace 200 is directed to the interior of the gas treatment box 100. A one-way valve is provided in the pipeline connecting the smelting furnace 200 and the gas treatment box 100 to prevent the liquid from flowing back to the interior of the smelting furnace 200 under the action of pressure, and the liquid enters the interior of the gas treatment box 100 for the first treatment, and enters above the water level inside the gas treatment box 100, and the air pressure inside the gas treatment box 100 is increased, and the pressure valve 120 is opened. The greater the tail gas generated by the smelting furnace 200, the greater the air pressure inside the gas treatment box 100, and the greater the blowing force on the fan 500, and it is discharged through the exhaust channel 110; When the gas is discharged, the fan 500 is blown to rotate, so that the fan 500 drives the first pulley 600 and the second pulley 430 to rotate, so that the second pulley 430 drives the extrusion head 410 to contact the airbag 322, and pushes the blocking plate 320 and the force plate 340 to rotate, so that the guide hole 321 corresponds to the atomizing nozzle 311, and the liquid is sprayed out. At the same time, when the force plate 340 rotates, the spring 332 is squeezed, so that the spring 332 is compressed and stored, and after the extrusion head 410 and the airbag 322 are offset, the force plate 340 and the blocking plate 320 are pushed to reset to block the atomizing nozzle 311; When the water pump is started, the water pump will transport the liquid in the gas treatment box 100 to the inside of the shell 310 and spray it out through the atomizing nozzle 311, and the liquid will be filtered by the filtering device 700 during the transportation process.

[0041] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.
