Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, and more specifically to a device for treating waste gas from metal smelting. Background Technology

[0002] Metal smelting refers to the process of extracting metallic elements from raw ores using various physical and chemical methods. This process typically includes several stages: ore mining, crushing, screening, smelting, and refining. Different metals (such as iron, copper, aluminum, and silver) require different smelting technologies and processes. The waste gases generated during metal smelting mainly include sulfur dioxide (SO2), carbon dioxide (CO2), carbon monoxide (CO), nitrogen oxides (NOx), particulate matter, and some harmful gases such as benzo[a]pyrene and sulfides. If these waste gases are not treated, they will cause air pollution and affect the environment and human health.

[0003] Existing metal smelting waste gas treatment devices, such as the environmentally friendly industrial metal smelting waste gas treatment device disclosed in Chinese invention patent publication number CN114042372 B, include an air inlet, a housing, a spray mechanism, a neutralization mechanism, a wastewater treatment mechanism, an adsorption mechanism, and an air outlet; the housing has an air inlet at one end; a spray mechanism is located on one side of the air inlet; a neutralization mechanism is located on one side of the spray mechanism; a wastewater treatment mechanism is located on one side of the neutralization mechanism; an adsorption mechanism is located on one side of the neutralization mechanism; and an air outlet is located at one end of the adsorption mechanism, which is connected to a centrifugal fan via a pipe.

[0004] However, during operation, it is difficult to cool down the high-temperature flue gas by simply spraying water through the spraying mechanism. This can easily lead to stress corrosion cracking of stainless steel caused by the discharge of high-temperature flue gas, increasing the maintenance cost of the equipment. Moreover, the high-temperature flue gas contains a large amount of heat energy and valuable metal elements. If these are not recycled, it will waste resources and increase the environmental burden. In view of this, we propose a metal smelting waste gas treatment device for cooling down high-temperature flue gas. Summary of the Invention

[0005] The purpose of this invention is to provide a device for treating waste gas from metal smelting, so as to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides a device for treating waste gas from metal smelting, comprising: The device body has a supporting base block at the bottom middle part and a mounting plate at the top, with a supporting block on the top surface of the mounting plate. An adjusting block is installed inside the main body of the device. Multiple adjusting rods are provided inside the adjusting block. A meshing gear is provided on the outer side of one end of the adjusting rod, and an adjusting motor is provided on the other end of the adjusting rod. A mounting block is provided at the bottom end of the adjusting rod. A heat dissipation assembly, comprising a heat dissipation copper plate and a heat dissipation water tank, wherein the heat dissipation copper plate is installed on the inner side of the main body of the device, and the heat dissipation water tank is installed on the top of the main body of the device. A processing block is installed at the bottom of the main body of the device. One end of the processing block is provided with an openable cabinet door, and the top surface of the processing block is provided with a smoke conveying pipe. A stabilizing base is fitted to the bottom of the radiator, and electric push rods are provided at the four corners of the bottom of the stabilizing base. The smoke exhaust assembly includes a smoke exhaust pipe, which is installed on one side of the main body of the device near the edge and is used for detecting the emission of smoke. A water tank top cover is installed on top of the radiator water tank. A water temperature sensor is provided at the top of the water tank top cover, and a detection rod is provided at the bottom of the water temperature sensor.

[0007] In the above technical solution, the support block is fixedly installed in the middle part of the bottom of the device body, the mounting plate is snapped onto the middle part of the top of the device body, the support block is fixedly connected to the mounting plate, the device body can be installed on the inner side of the support block, and the support block provides support and stability. At the same time, the support block at the top of the mounting plate can connect and support the heat dissipation tank.

[0008] In the above technical solution, the adjusting rod is rotatably mounted on the inner side of the adjusting block, the meshing gear is fixedly mounted on the outer side of one end of the adjusting rod, the adjusting motor is fixedly mounted on the other end of the adjusting rod, and the mounting block is fixedly connected to the adjusting rod. When the adjusting motor rotates through the motor output end, it will drive the adjusting rod to rotate simultaneously. Since the wrap angle between the meshing gears matches each other, when the adjusting rod rotates, it will drive the remaining meshing gear at one end of the adjusting rod to rotate simultaneously in one direction, with a rotation angle of 30°. At this time, the mounting block will also drive the heat dissipation copper plate to move, so as to control the heat dissipation and cooling efficiency by controlling the contact area between the heat dissipation copper plate and the flue gas.

[0009] In the above technical solution, further, the heat dissipation assembly includes multiple sets of heat dissipation copper plates, with multiple sets of heat dissipation bends on the inner side of each set of heat dissipation copper plates. Multiple sets of flexible joints are provided on the outer sides of both ends of each set of heat dissipation bends. Multiple sets of drainage copper pipes are provided on the inner side of the other end of each set of flexible joints. Multiple sets of micro water pumps are provided at one end of each set of drainage copper pipes. The multiple sets of heat dissipation bends are fixedly installed on the inner side of the multiple sets of heat dissipation copper plates. The multiple sets of flexible joints are rotatably installed on the outer sides of both ends of the multiple sets of heat dissipation bends. The multiple sets of drainage copper pipes are fixedly installed on the outer sides of the multiple sets of flexible joints. On the other end of the head, multiple sets of miniature water pumps are rotatably installed at one end of multiple sets of drain copper pipes. When the high-temperature flue gas comes into contact with the heat dissipation copper plate, the high temperature in the flue gas will gradually transfer to the heat dissipation copper plate. The multiple sets of miniature water pumps will continuously draw the heat dissipation water into the inside of the drain copper pipes, and then circulate it into the inside of multiple sets of heat dissipation bends through the drain copper pipes. The heat dissipation bends located inside the heat dissipation copper plate will absorb the heat on the heat dissipation copper plate. The water flowing in the heat dissipation bends will carry the heat out and into the inside of the heat dissipation tank.

[0010] In the above technical solution, further, the heat dissipation assembly also includes a heat dissipation tank. Two sets of first copper pipes are provided inside the heat dissipation tank, and two sets of second copper pipes are provided in the middle part of the inner side of the heat dissipation tank. Each of the first and second copper pipes has a circulation bend at one end. A water inlet is opened on the top surface of the circulation bend. An opening / closing valve is provided between the second copper pipe and the circulation bend. Each of the first and second copper pipes has a connecting secondary pipe at its bottom end. A positioning sleeve is provided on the outer side of the bottom end of each of the first and second copper pipes. The first copper pipe is fixedly installed inside the heat dissipation tank, and the second copper pipe is fixedly installed in the middle part of the inner side of the heat dissipation tank. The circulation bend is fixedly connected to the first and second copper pipes. The water inlet is arranged in a linear array on the top surface of the circulation bend. The opening / closing valve is fixedly installed... The device is fixedly installed between the second copper pipe and the circulation bend. The connecting sub-pipe is fixedly connected to the first and second copper pipes. The positioning sleeve is fitted onto the outer side of the bottom end of the first and second copper pipes. During heat dissipation and cooling, the water pump on one side of the heat dissipation tank draws water from the heat dissipation tank into the inner side of the first copper pipe through the water inlet hole on the surface of the circulation bend. When the water reaches the bottom, it enters the inner side of the mounting plate through the connecting sub-pipe. At the same time, it is discharged through the connecting sub-pipe on the other side of the bottom end of the first copper pipe and re-enters the inner side of the first copper pipe for circulation, thereby improving the cooling efficiency of the device. When the temperature of the flue gas is too high, the valve will open, allowing the water pump to draw water from the heat dissipation tank into the inner side of the second copper pipe through the water inlet hole on the surface of the circulation bend, thereby increasing the cooling effect.

[0011] In the above technical solution, the hinged cabinet door is installed in the middle part of one end of the processing block, and the smoke conveying pipe is fixedly installed on the top surface of the processing block near the left end. The cabinet door can be opened, and then the metal copper is placed inside the processing block. The metal copper is smelted by heating it at high temperature inside the processing block. The flue gas generated during the smelting process will enter the inside of the main body of the device through the smoke conveying pipe for treatment.

[0012] In the above technical solution, the electric push rods are further fixedly installed at the four corners of the bottom of the stable base, and there are two sets of electric push rods. When the heat dissipation copper plate is working, the dust and heavy metal dust in the flue gas will adhere to the surface of the heat dissipation copper plate. When cleaning is required, the stable base can be pushed upward by the electric push rods. Since the mounting plate is connected to the stable base through the support block, and the mounting plate is also snapped on the inner top of the device body, when the stable base moves upward, the mounting plate will also move upward, and at the same time, it will drive the heat dissipation copper plate away from the device body, which facilitates the cleaning of the dust and heavy metal dust adhering to the surface of the heat dissipation copper plate.

[0013] In the above technical solution, further, the smoke exhaust assembly includes a smoke exhaust pipe. A stable outer frame is provided on the outer side of the smoke exhaust pipe near its bottom end. A waterproof top block is provided on the outer side of the top end of the smoke exhaust pipe. A temperature sensor is provided on the outer side of the smoke exhaust pipe near the pipe connection. The stable outer frame is fixedly installed on the outer side of the smoke exhaust pipe near its bottom end. The waterproof top block is fixedly installed on the outer side of the top end of the smoke exhaust pipe. The temperature sensor is fixedly installed on the outer side of the smoke exhaust pipe near the pipe connection. The temperature sensor is a NiCrSi-Ni202 (S-type thermocouple), suitable for flue gas detection requiring precise high-temperature measurement. The smoke exhaust pipe can be installed on one side of the device body through the stable outer frame. During flue gas emission, when the circuits composed of different materials (platinum-rhodium alloy and platinum) at both ends of the temperature sensor are at different temperatures, a small voltage will be generated at both ends. The magnitude of this voltage is proportional to the temperature difference. By measuring this thermoelectric potential, the temperature at the measuring end can be accurately calculated, thereby achieving temperature monitoring in high-temperature environments. This facilitates the determination of whether the emitted flue gas temperature is too high, and thus allows for adjustment of the cooling method.

[0014] In the above technical solution, the water temperature sensor is further fixedly installed on the top of the water tank cover, and the detection rod is fixedly connected to the water temperature sensor. The water temperature sensor is an NTC thermistor, model D508-10K, which is suitable for measuring and detecting water temperature between 0°C and ~100°C. The water temperature sensor at the top of the water tank cover can detect the water temperature in the cooling water tank through the NTC thermistor inside the detection rod. When the temperature rises, the electron movement in the material increases, resulting in a decrease in resistance, thereby increasing the current through it, reflecting the temperature change. When the water temperature in the cooling water tank exceeds 80°C, the water tank at the front of the main body of the device will pump out the water from the cooling water tank through a water pump. At the same time, the water tank at the rear of the main body of the device will pump cold water into the cooling water tank through a water pump, so that the cooling efficiency is not affected during operation, and the hot water in the water tank can be collected for secondary use.

[0015] The beneficial effects of this invention are: 1. In this metal smelting waste gas treatment device, when the regulating motor rotates through the motor output end, it will drive the regulating rod to rotate simultaneously. Since the wrap angle between the meshing gears matches each other, when the regulating rod rotates, it will drive the meshing gear at one end of the remaining regulating rod to rotate to the left or right simultaneously through the meshing gear. The rotation angle is 30°. At this time, the mounting block will also drive the heat dissipation copper plate to move, so as to control the heat dissipation and cooling efficiency by controlling the contact area between the heat dissipation copper plate and the flue gas.

[0016] 2. In this metal smelting waste gas treatment device, when the high-temperature flue gas comes into contact with the heat dissipation copper plate, the high temperature in the flue gas will gradually transfer to the heat dissipation copper plate. Multiple sets of micro water pumps will continuously draw heat dissipation water into the inside of the drain copper pipe. Then, the drain copper pipe enters the inside of multiple sets of heat dissipation bends for circulation. The heat dissipation bends located inside the heat dissipation copper plate will absorb the heat on the heat dissipation copper plate. The water flowing in the heat dissipation bends will carry the heat out and into the inside of the heat dissipation water tank.

[0017] 3. In the metal smelting waste gas treatment device, during heat dissipation and cooling, a water pump on one side of the heat dissipation tank draws water from the tank into the inner side of the first copper pipe through an inlet hole on the surface of the circulation bend. The water then flows to the bottom and enters the inner side of the mounting plate through a connecting secondary pipe. Simultaneously, it exits through a connecting secondary pipe on the other side of the bottom of the first copper pipe and re-enters the inner side of the first copper pipe for circulation, thus improving the cooling efficiency of the device. When the flue gas temperature is too high, the valve opens, causing the water pump to draw water from the heat dissipation tank into the inner side of the second copper pipe through an inlet hole on the surface of the circulation bend, further enhancing the cooling effect.

[0018] 4. When the metal smelting waste gas treatment device needs cleaning, the stabilizing base can be pushed upward by an electric push rod. Since the mounting plate is connected to the stabilizing base through the support block, and the mounting plate is also snapped onto the inner top of the main body of the device, when the stabilizing base moves upward, the mounting plate will also move upward, thereby driving the heat dissipation copper plate away from the main body of the device, which facilitates the cleaning of dust and heavy metal fumes adhering to the surface of the heat dissipation copper plate.

[0035] Example 1: Please see Figures 1-10 As shown, this embodiment provides a device for treating waste gas from metal smelting.

[0036] The device includes: a main body 1, with a supporting base block 101 at the middle of its bottom end; a mounting plate 102 at the top of the main body 1, with a supporting block 103 on the top surface of the mounting plate 102; an adjusting block 2, installed inside the main body 1, with multiple adjusting rods 201 on the inner side of the adjusting block 2; a meshing gear 202 on the outer side of one end of each adjusting rod 201; an adjusting motor 203 at the other end of each adjusting rod 201; a mounting block 204 at the bottom end of each adjusting rod 201; and a heat dissipation assembly, including a heat dissipation copper plate 3 and a heat dissipation water tank 7. Furthermore, the heat dissipation copper plate 3 is installed inside the main body 1 of the device, the heat dissipation water tank 7 is installed at the top of the main body 1 of the device, the processing block 4 is installed at the bottom of the main body 1 of the device, one end of the processing block 4 is provided with an opening and closing cabinet door 401, the top surface of the processing block 4 is provided with a smoke conveying pipe 402, the stabilizing base 5 is fitted to the bottom of the heat dissipation water tank 7, the four corners of the bottom of the stabilizing base 5 are provided with electric push rods 501, the smoke exhaust assembly includes a smoke exhaust pipe 6, the smoke exhaust pipe 6 is installed on one side of the main body 1 near the edge, and is used for smoke emission detection, and the water tank top cover. 8. The top cover 8 of the water tank is installed on the top of the heat dissipation water tank 7. A water temperature sensor 801 is provided on the top of the top cover 8. A detection rod 802 is provided at the bottom of the water temperature sensor 801. When cooling is performed, the main body 1 of the device can be installed on the top of the processing block 4 through the support block 101 at the bottom. At the same time, the smoke pipe 402 provided on the top of the processing block 4 can enter the inner side of the main body 1 of the device. Meanwhile, the support block 103 provided on the top of the mounting plate 102 can be connected and fixed to the stable base 5. When the temperature of the flue gas discharged from the exhaust pipe 6 is not high, the adjustment rod 201 can be rotated by adjusting the motor 203. This causes the adjusting rod 201 to rotate to the right by the meshing gear 202, with a rotation angle of 30°. At this time, the heat dissipation copper plate 3 will not block the flue gas, thus accelerating the exhaust speed. When the adjusting rod 201 rotates, it drives the other adjusting rods 201 to rotate to the left by the meshing gear 202, which increases the contact area between the flue gas and the heat dissipation copper plate 3. The heat dissipation bend 301 on the inner side of the heat dissipation copper plate 3 can dissipate heat through the cooling water flowing inside. At the same time, the cooling water that has absorbed heat will enter the inner side of the heat dissipation water tank 7 through the drain copper pipe 303, thereby cooling the flue gas.

[0037] Example 2: This embodiment provides a device for treating waste gas from metal smelting, in addition to the features described in the above embodiment. In addition to the technical solution, it also has the following technical features: The support base 101 is fixedly installed in the middle part of the bottom of the device body 1, and the mounting plate 102 is snapped onto the middle part of the top of the device body 1. The support block 103 is fixedly connected to the mounting plate 102. The device body 1 can be installed on the inner side of the support base 101 and supported and stabilized by the support base 101. At the same time, the support block 103 at the top of the mounting plate 102 can connect and support the heat dissipation tank 7.

[0038] Example 3: This embodiment provides a device for treating waste gas from metal smelting, in addition to the features described in the above embodiment. In addition to the technical solution, it also has the following technical features: The adjusting rod 201 is rotatably mounted on the inner side of the adjusting block 2, and the meshing gear 202 is fixed. The adjusting rod 201 is installed on the outer side of one end, and the adjusting motor 203 is fixedly installed on the other end of the adjusting rod 201. The mounting block 204 is fixedly connected to the adjusting rod 201. When the adjusting motor 203 rotates through its output end, it will drive the adjusting rod 201 to rotate simultaneously. Since the wrap angle between the meshing gears 202 matches each other, when the adjusting rod 201 rotates, it will drive the remaining meshing gear 202 at one end of the adjusting rod 201 to rotate simultaneously in one direction. 3 is a stepper motor. By preset 30°, the motor sends about 17 pulses to achieve a 30° rotation. At the same time, according to the positive sequence of pulses, the motor can rotate to the left or right in a predetermined direction. The control system can realize the forward (right) or reverse (left) movement of the motor by changing the direction or sequence of the pulses, thereby precisely controlling the rotation angle of the motor. At this time, the mounting block 204 will also drive the heat dissipation copper plate 3 to rotate at a 30° angle, so as to control the heat dissipation copper plate 3 and the flue gas contact area to control the heat dissipation and cooling efficiency.

The positioning sleeve 707 is fitted onto the outer side of the bottom end of the first copper pipe 701 and the second copper pipe 702. During heat dissipation and cooling, a water pump on one side of the heat dissipation tank 7 draws water from the heat dissipation tank 7 into the inner side of the first copper pipe 701 through the water inlet 704 on the surface of the circulation bend 703, allowing the water to flow to the bottom end. When the temperature of the flue gas is too high, the valve 705 will open, allowing the water pump to draw water from the cooling water tank 7 through the water inlet hole 704 on the surface of the circulation bend 703 into the inner side of the second copper pipe 702 for circulation, thereby increasing the cooling efficiency of the device. When the temperature of the flue gas is too high, the water pump will draw water from the cooling water tank 7 through the water inlet hole 704 on the surface of the circulation bend 703 into the inner side of the second copper pipe 702 for circulation, thereby increasing the cooling effect.

The flue gas generated during the smelting process will enter the inside of the device body 1 through the smoke conveying pipe 402 for treatment.

[0041] Example 7: This embodiment provides a device for treating waste gas from metal smelting, in addition to the features described in the above embodiment. In addition to the technical solution, it also has the following technical features: Among them, the electric push rods 501 are fixedly installed at the four corners of the bottom of the stable base 5, and there are two sets of electric push rods 501. When the heat dissipation copper plate 3 is working, the dust and heavy metal dust in the flue gas will adhere to the surface of the heat dissipation copper plate 3. When cleaning is required, the stable base 5 can be pushed upward by the electric push rods 501. Since the mounting plate 102 is connected to the stable base 5 through the support block 103, and the mounting plate 102 is snapped on the inner side of the top of the device body 1, when the stable base 5 moves upward, the mounting plate 102 will also move upward, and at the same time drive the heat dissipation copper plate 3 away from the device body 1, which facilitates the cleaning of the dust and heavy metal dust adhering to the surface of the heat dissipation copper plate 3.

[0042] Example 8: This embodiment provides a device for treating waste gas from metal smelting, in addition to the features described in the above embodiment. In addition to the technical solution, it also has the following technical features: The exhaust assembly includes an exhaust pipe 6. A stabilizing frame 601 is provided on the outer side of the exhaust pipe 6 near its bottom end. A waterproof top block 602 is provided on the outer side of the top end of the exhaust pipe 6. A temperature sensor 603 is provided on the outer side of the exhaust pipe 6 near the pipe connection. The stabilizing frame 601 is fixedly installed on the outer side of the exhaust pipe 6 near its bottom end. The waterproof top block 602 is fixedly installed on the outer side of the top end of the exhaust pipe 6. The temperature sensor 603 is a NiCrSi-Ni202 (S-type thermocouple) suitable for flue gas detection requiring high-temperature and accurate measurement. The exhaust pipe 6 can be installed on one side of the main body 1 of the device through the stabilizing frame 601. When flue gas is discharged, when the circuit composed of different materials (platinum-rhodium alloy and platinum) at both ends of the temperature sensor 603 is at different temperatures, a small voltage will be generated at both ends. The magnitude of this voltage is proportional to the temperature difference. By measuring this thermoelectric potential, the temperature at the measuring end can be accurately calculated, thereby enabling temperature monitoring in high-temperature environments. This facilitates the determination of whether the temperature of the exhaust gas is too high, allowing for adjustments to the cooling method.

[0043] Example 9: This embodiment provides a device for treating waste gas from metal smelting, in addition to the features described in the above embodiment. In addition to the technical solution, it also has the following technical features: The water temperature sensor 801 is fixedly installed on the top of the water tank cover 8. The detection rod 802 is fixedly connected to the water temperature sensor 801. The water temperature sensor 801 is an NTC thermistor, model D508-10K, which is suitable for measuring and detecting water temperature between 0°C and ~100°C. The water temperature sensor 801 at the top of the water tank cover 8 can detect the water temperature in the cooling water tank 7 through the NTC thermistor inside the detection rod 802. When the temperature rises, the electron movement in the material increases, resulting in a decrease in resistance value, thereby increasing the current through it, reflecting the temperature change. When the water temperature in the cooling water tank 7 exceeds 80°C, the water tank at the front end of the device body 1 will pump out the water from the cooling water tank through a water pump. At the same time, the water tank at the rear end of the device body 1 will pump cold water into the cooling water tank through a water pump, so that the cooling efficiency is not affected during operation. The hot water in the water tank can be collected for secondary use.
