Description

Technical Field

[0001] This utility model relates to the field of flue gas treatment technology, specifically to an electrified treatment device for mercury-containing flue gas in non-ferrous smelting. Background Technology

[0002] Non-ferrous smelting refers to the production process of separating associated elements from ores, concentrates, secondary resources or other materials to produce non-ferrous metals or their compounds. During the smelting and refining process, mercury-containing flue gas is generated. In order to meet emission standards, mercury-containing flue gas needs to be treated. Therefore, treatment agents are sprayed in purification tanks for treatment.

[0003] However, existing electrification treatment devices for mercury-containing flue gas in non-ferrous smelting still have the following drawbacks during use:

[0004] 1. During flue gas transportation, the flue gas is introduced into the purification tank from the side. As the flue gas flows from bottom to top in the purification tank, its distribution is uneven. Consequently, when the treatment agent is sprayed, the contact between the treatment agent and the flue gas is uneven, reducing the treatment effect of the flue gas.

[0005] 2. The spraying position of the treatment agent in the existing flue gas electrification treatment device is fixed and cannot be adjusted according to the flow speed of the flue gas in the purification tank. When the flue gas flow speed is too fast, the interaction time between the flue gas and the treatment agent will be shortened, and the treatment effect will not be achieved. On the other hand, if the flue gas flow speed is too slow, the long-term interaction between the flue gas and the treatment agent will hinder the normal flow of the flue gas and reduce the efficiency of flue gas treatment. Utility Model Content

[0006] The purpose of this invention is to address the problems of uneven distribution of flue gas within the purification tank, resulting in uneven contact between the treatment agent and the flue gas during spraying, thus reducing the treatment effect, and the inability to adjust the spraying position of the treatment agent according to the flow rate of the flue gas within the purification tank. This leads to situations where the treatment effect is not achieved when the flue gas flow rate is too fast, and the treatment efficiency is reduced when the flow rate is too slow. Therefore, this invention provides an electrified treatment device for mercury-containing flue gas in non-ferrous smelting.

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] An electrified treatment device for mercury-containing flue gas in non-ferrous smelting includes a purification tank. A flue gas inlet is fixedly connected to the left side of the bottom of the purification tank, a flue gas outlet is fixedly connected to the top of the purification tank, a sewage outlet is fixedly connected to the front side of the bottom of the purification tank, an infusion pipe is fixedly connected to the right side of the top of the purification tank, a mounting base is fixedly installed inside the top of the purification tank, a circulation pipe is fixedly connected between the right side of the bottom of the purification tank and the bottom of the infusion pipe, a suction pump is fixedly installed in the middle of the circulation pipe, a threaded pipe is rotatably connected to the bottom of the infusion pipe inside the purification tank, a flow divider is fixedly installed at the bottom of the threaded pipe, spray pipes are evenly fixedly connected to the periphery of the flow divider, a flow collector is fixedly installed inside the middle of the purification tank, and an adjustment component is provided between the inner side of the flow collector and the flow divider.

[0009] Furthermore, the infusion tube is bent vertically downward at the center of the purification tank, and its bottom passes through the center of the mounting base and is fixedly installed at the center of the mounting base.

[0010] Furthermore, the top of the circulation tube is connected to the infusion tube, the bottom of the circulation tube extends into the interior of the purification tank, and the connection between the bottom of the circulation tube and the purification tank is located below the flue gas inlet, so that the liquid level at the bottom of the purification tank does not exceed the flue gas inlet.

[0011] Furthermore, the nozzle and the distributor tube are connected, and nozzles are evenly arranged at the bottom of the nozzle, so that the treatment agent can be evenly sprayed downward through the nozzle and nozzles.

[0012] Furthermore, the hood is shaped like a funnel with the opening gradually decreasing from bottom to top. The hood is located above the connection between the smoke inlet and the purification tank, and the edge of the hood is evenly provided with notches at the connection between the edge of the hood and the inner wall of the purification tank. This allows the flue gas at the inner edge of the purification tank to flow upward normally through the notches, while the flue gas in the middle can flow upward from the middle through the hood.

[0013] Furthermore, the adjustment assembly includes a second mounting base, which is fixedly mounted on the inner side of the flow collector. A rotating shaft is rotatably connected to the center of the second mounting base. A fan blade is fixedly mounted on the bottom end of the rotating shaft. A connecting sleeve is slidably sleeved on the top of the rotating shaft. A spring is fixedly connected between the top end of the rotating shaft and the inner wall of the connecting sleeve. A rotating ring is rotatably connected to the bottom of the first mounting base. A transmission rod is uniformly driven between the top end of the flow divider and the rotating ring. A counterweight is hinged to the periphery of the transmission rod.

[0014] Furthermore, the transmission rods are arranged in pairs and evenly distributed between the diverter cylinder and the rotating ring. One end of each pair of transmission rods is hinged to the top of the diverter cylinder and the bottom of the rotating ring, respectively, and the other end extends outward and is hinged to the counterweight. Therefore, when the counterweight moves outward, the transmission rods can pull the diverter cylinder upward.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model, through the design of the flow collector, enables the flue gas to move upward more evenly in the purification tank. At the same time, the rotation of the fan blades driven by the flue gas flow can drive the flow divider and the spray nozzle to rotate, thereby making the treatment agent spray downward more evenly, so as to ensure uniform contact between the treatment agent and the flue gas and improve the treatment effect of the flue gas.

[0017] 2. This utility model, through the combined design of the flow collector and the adjustment component, allows the flow divider and nozzle to move upward when the flue gas flow speed increases, thus extending the contact distance between the flue gas and the sprayed treatment agent and avoiding poor treatment effect. Conversely, when the flue gas flow speed decreases, the flow divider and nozzle can move downward, shortening the contact distance between the flue gas and the sprayed treatment agent and avoiding obstruction of the upward flow of flue gas, thereby ensuring the efficiency of flue gas treatment.

[0028] An electrified treatment device for mercury-containing flue gas in non-ferrous smelting according to a preferred embodiment of the present invention will be described in detail below, such as Figures 1-4 As shown, an electrified treatment device for mercury-containing flue gas in non-ferrous smelting includes a purification tank 1. A flue gas inlet 2 is fixedly connected to the left side of the bottom of the purification tank 1, a flue gas outlet 3 is fixedly connected to the top of the purification tank 1, a sewage outlet 4 is fixedly connected to the front side of the bottom of the purification tank 1, and an infusion pipe 5 is fixedly connected to the right side of the top of the purification tank 1. An installation base 6 is fixedly installed inside the top of the purification tank 1. The infusion pipe 5 is bent vertically downward at the center of the interior of the purification tank 1, and its bottom passes through the center of the installation base 6 and is fixedly installed at the center of the installation base 6.

[0029] A circulation pipe 7 is fixedly connected between the bottom right side of the purification tank 1 and the bottom of the infusion pipe 5. A suction pump 8 is fixedly installed in the middle of the circulation pipe 7. The top of the circulation pipe 7 is connected to the infusion pipe 5. The bottom of the circulation pipe 7 extends into the interior of the purification tank 1. The connection between the bottom of the circulation pipe 7 and the purification tank 1 is located below the smoke inlet 2, so that the liquid level at the bottom of the purification tank 1 will not exceed the smoke inlet 2.

[0030] The infusion tube 5 is located inside the purification tank 1 and is rotatably connected to the bottom limit of the threaded tube 9. The bottom of the threaded tube 9 is fixedly installed with a diverter cylinder 10. The periphery of the diverter cylinder 10 is uniformly fixedly connected with a spray pipe 11. The spray pipe 11 and the diverter cylinder 10 are connected to each other, and the bottom of the spray pipe 11 is uniformly provided with a nozzle 111, so that the treatment agent can be uniformly sprayed downward through the spray pipe 11 and the nozzle 111.

[0031] A flow collector 12 is fixedly installed inside the middle of the purification tank 1. The flow collector 12 is in the shape of a trumpet with the opening gradually decreasing from bottom to top. The flow collector 12 is located above the connection between the smoke inlet 2 and the purification tank 1. The edge of the flow collector 12 is evenly provided with notches at the connection between it and the inner wall of the purification tank 1, so that the flue gas at the inner edge of the purification tank 1 can flow upward normally through the notches, while the flue gas in the middle can flow upward from the middle through the flow collector 12.

[0032] Furthermore, such as Figures 4-8 As shown, an adjustment assembly 13 is provided between the inner side of the flow collector 12 and the flow divider 10. The adjustment assembly 13 includes a second mounting base 131. The second mounting base 131 is fixedly installed on the inner side of the flow collector 12. A rotating shaft 132 is rotatably connected to the center of the second mounting base 131. A fan blade 133 is fixedly installed at the bottom end of the rotating shaft 132. A connecting sleeve 134 is slidably sleeved at the top of the rotating shaft 132. A spring 135 is fixedly connected between the top end of the rotating shaft 132 and the inner wall of the connecting sleeve 134. A rotating ring 136 is rotatably connected to the bottom of the first mounting base 16. A transmission rod 137 is uniformly connected between the top end of the flow divider 10 and the rotating ring 136. A counterweight 138 is hinged to the outer periphery of the transmission rod 137.

[0033] The transmission rods 137 are arranged in pairs and are evenly distributed between the diverter cylinder 10 and the rotating ring 136. One end of each pair of transmission rods 137 is hinged to the top of the diverter cylinder 10 and the bottom of the rotating ring 136, respectively. The other end extends outward and is hinged to the counterweight block 138. Therefore, when the counterweight block 138 moves outward, the transmission rods 137 can pull the diverter cylinder 10 upward.

[0034] The working principle of this utility model is as follows:

[0035] During flue gas treatment, the flue gas enters the interior of the purification tank 1 through the flue gas inlet 2 and moves upward inside the purification tank 1 under pressure. Then, the treatment agent is introduced into the purification tank 1 through the infusion pipe 5. The treatment agent enters the interior of the diversion cylinder 10 through the infusion pipe 5 and the threaded pipe 9, and flows into the nozzles 11 in the diversion cylinder 10. Finally, it is sprayed downward from the evenly distributed nozzles 111 to treat the flue gas flowing upward in the purification tank 1.

[0036] After the sprayed treatment agent reacts with the flue gas, it falls to the bottom of the purification tank 1. The treated flue gas is discharged through the exhaust port 3 and enters the next treatment unit. The treatment agent that falls to the bottom of the purification tank 1 is then reprocessed and, under the action of the circulation pipe 7 and the suction pump 8, the treatment agent at the bottom is re-extracted into the infusion pipe 5 to achieve recycling.

[0037] During the process of flue gas entering the purification tank 1, the flue gas at the inner edge flows upward normally through the gap at the edge of the hood 12, while the flue gas in the middle flows upward after being concentrated by the hood 12. During the flow, the fan blades 133 can be rotated to concentrate the flue gas and blow it upward, so that the flue gas flows upward more evenly after passing through the hood 12, so that the treatment agent and flue gas are in more uniform contact.

[0038] As the flue gas flows upward through the collector hood 12, it drives the fan blades 133 to rotate, which in turn drives the rotating shaft 132 and the connecting sleeve 134 to rotate. The connecting sleeve 134 then drives the distributor 10 and the nozzle 11 to rotate. During the rotation of the nozzle 11, the treatment agent sprayed from the nozzle 111 comes into better and more uniform contact with the flue gas.

[0039] When the flue gas flow speed increases, the speed at which the fan blade 133 rotates also increases, which in turn drives the flow divider 10 and nozzle 11 to rotate faster. This, in turn, through the action of the transmission rod 137 and in conjunction with the limiting rotation connection of the rotating ring 136 at the bottom of the mounting base 6, drives the counterweight 138 to rotate faster. Consequently, the counterweight 138 moves outward under the action of centrifugal force, and under the action of the transmission rod 137, it pulls the flow divider 10 and nozzle 11 upward. Therefore, when the flue gas flows upward faster, the upward movement of the flow divider 10 and nozzle 11 results in a longer contact distance between the flue gas and the sprayed treatment agent, thus avoiding the phenomenon of poor treatment effect.

[0040] When the flue gas flow speed slows down, the rotation speed of the counterweight 138 also slows down, which reduces the outward centrifugal force on the counterweight 138. As a result, under the restoring force of the spring 135, the connecting sleeve 134 can be pulled downward, which in turn drives the diverter cylinder 10 and the nozzle 11 to move downward. Therefore, when the flue gas flow speed slows down, the downward movement of the diverter cylinder 10 and the nozzle 11 makes the interaction distance between the flue gas and the sprayed treatment agent shorter, avoiding obstruction of the upward flow of the flue gas and ensuring the efficiency of flue gas treatment.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
