Description

Technical Field

[0001] This invention relates to the field of oil stain prevention and removal technology, and in particular to a quenching oil tank flue gas treatment device. Background Technology

[0002] The quenching process of metal materials in an oil bath generates a large amount of fumes. Direct emission of these fumes into the workshop not only pollutes and damages the equipment, but also harms the health of the workshop workers.

[0003] In existing technologies, quenching oil tank flue gas treatment equipment can collect and centrally treat the flue gas generated during quenching, achieving low-pollution centralized emission of quenching oil tank flue gas. However, most existing related treatment equipment is a single static adsorption cleaning structure, which can only meet the adsorption cleaning and purification treatment of small batches of intermittently generated quenching flue gas. In particular, it is difficult to capture and detect the small amount of oil mist that remains in the flue gas. It is also difficult to judge, detect, and dynamically adjust based on the dynamic fluctuations of the flue gas and the adsorption cleaning status of the static adsorption structure. Consequently, it is difficult to continuously clean and adsorb large quantities of flue gas, affecting the continuous adsorption cleaning and purification treatment of large batches of flue gas. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a quenching oil tank flue gas treatment device. This invention minimizes the content of oil mist in the final emission of flue gas and can also predict the adsorption state of the static adsorption structure, reminding staff to check and replace the static adsorption structure in a timely manner, ensuring that the overall equipment continuously and efficiently adsorbs and treats the flue gas.

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] See attached document Figure 1 -Appendix Figure 9 A quenching oil tank flue gas treatment device includes an adsorption cleaning device, a combustion device 300, and a tail gas emission device 400. The adsorption structure can adsorb and remove most of the oil stains in the flue gas generated by the quenching oil tank, reducing the pollution level of the flue gas emissions. The combustion device 300 can fully combust some incompletely combusted substances in the flue gas, such as carbon monoxide, and can fully combust pollutants in the flue gas that cannot be adsorbed, further reducing the pollution of the flue gas emissions.

[0030] Specifically, the combustion device 300 includes a catalytic combustion chamber 320 at the bottom and a static adsorption chamber 310 at the top. The top of the static adsorption chamber 310 is connected to the bottom of the exhaust gas emission device 400 through a bent pipe. The static adsorption chamber 310 functions similarly to the adsorption structure, both adsorbing residual oil in the flue gas to reduce the amount of oil in the flue gas. The static adsorption structure can be made of adsorption materials such as activated carbon substrate, inorganic porous materials, and polymer porous materials. After the flue gas passes through these materials, the oil mist particles are captured and adsorbed, thus reducing the content of oil mist particles in the flue gas. The static adsorption materials need to be replaced regularly, and the replacement should be determined based on a comprehensive consideration of factors such as the adsorption capacity of the materials, the content of oil mist in the flue gas, and the ambient temperature.

[0031] Specifically, the adsorption cleaning device includes a first cleaning device 100 and a second cleaning device 200 arranged sequentially along the flue gas flow direction. The first cleaning device 100 is a static adsorption structure filled with adsorption material, which needs to be replaced by staff regularly. The second cleaning device 200 is a dynamic adsorption structure. By controlling the directional rotation of the internal structure, the flue gas exhaust gas that has undergone one purification process is driven to flow during the rotation. The flue gas exhaust gas located in the second cleaning device 200 comes into contact with and collides with the internal structure, thereby capturing the oil mist in the flue gas exhaust gas and reducing the smoke content in the flue gas exhaust gas.

[0032] The combustion device 300 is connected in series between the exhaust gas emission device 400 and the second cleaning device 200. The combustion device 300 is located at the end to burn the pollutants that cannot be adsorbed in the flue gas. At the same time, a static adsorption chamber 310 is also provided at the top of the combustion device 300, which can fully adsorb the remaining oil and some pollutants generated by the combustion, so as to minimize the discharge of oil and other pollutants through the exhaust gas emission device 400.

[0033] Specifically, the second cleaning device 200 includes an adsorption tank 210, a drive shaft 250 is rotatably connected inside the adsorption tank 210, and a first cleaning component 230 is fixed on the surface of the drive shaft 250. A drive gear 251 is provided at the bottom of the drive shaft 250. The drive gear 251 rotates to drive the drive shaft 250 and the first cleaning component 230 located in the adsorption tank 210 to rotate synchronously. An air inlet pipe 240 is provided at the bottom of the adsorption tank 210. The flue gas enters the adsorption tank 210 from the air inlet pipe 240 at the bottom, passes through the directional rotating first cleaning component 230 and is discharged from the pipe at the top. During the directional flow, the flue gas comes into contact with and collides with the first cleaning component 230, capturing the oil mist in the flue gas and eliminating the residual oil mist to the greatest extent.

[0034] Specifically, the exhaust emission device 400 includes an emission pipe 410 and a conical shielding component 430 located at the top of the emission pipe 410. A second cleaning component 440 with directional rotation is provided inside the shielding component 430. The second cleaning component 440 has a similar function to the first cleaning component 230. Both collide with the oil mist in the flue gas exhaust gas during directional rotation to capture the oil mist in the final residual part. An annular collection chamber is formed on the inner side of the bottom edge of the shielding component 430. Here, the shielding component 430 is conical with an inclined inner wall. The oil mist captured by the shielding component 430 forms oil droplets that flow downward along the inner wall surface of the shielding component 430. Under the combined action of gravity and centrifugal force, the droplets are thrown into the collection chamber to achieve collection.

[0035] The aforementioned shielding component 430 is fixedly connected to the emission pipe 410 via a connecting workpiece 420. The connecting workpiece 420 includes a connecting ring 421 and a connecting rod 422. Through the above structure, the shielding component 430 is installed on the top of the emission pipe 410, which not only prevents rainwater from entering, but also captures some residual oil mist in the flue gas, thus achieving environmentally friendly emissions.

[0036] Specifically, the shielding assembly 430 includes a shielding cone 431 located at the top, a horizontal first receiving ring 433 fixed at the bottom of the shielding cone 431, and a second receiving ring 432 fixed inside the first receiving ring 433. The shielding cone 431, the first receiving ring 433, and the second receiving ring 432 together form an annular collection chamber. A drain pipe with a built-in opening and closing valve is also provided at the bottom of the first receiving ring 433. Normally, the drain pipe with the opening and closing valve is either closed or open at a low flow rate, allowing oil to gradually collect in the collection chamber. When the oil has collected to a predetermined height, the valve is opened. Oil stains can be discharged through pipes, achieving one-time collection and discharge of oil stains in the collection room. By calculating the time of one collection and discharge, combined with the oil mist content in the flue gas, the state of the above-mentioned adsorption structure can be judged. When the time of one collection and discharge of oil stains is too short, which is less than the set time, it means that the adsorption structure cannot play the intended adsorption effect on oil stains. The relevant adsorption structure needs to be replaced to reduce the burden on the dynamic adsorption structure to treat flue gas. At the same time, it can also achieve real-time feedback to avoid the impact of long-term unqualified flue gas emissions on the surrounding environment.

[0037] An oil detection element 443 is installed at the bottom of the second cleaning component 440, located in the collection chamber. The oil detection element 443 can detect the height parameter of the oil in the collection chamber, and thus determine the oil content in the collection chamber. The oil detection element 443 is telescopically oriented. Under normal conditions, the oil detection element 443 is in an extended state, with its end located at a predetermined position at the bottom, at a certain distance from the bottom of the collection chamber. When the oil height in the collection chamber exceeds the above-mentioned distance after a predetermined oil collection time, the detection structure at the end of the oil detection element 443 can come into contact with the oil in the collection chamber to realize the detection process.

[0038] After the predetermined detection time, once the oil level is determined to be stable at a constant height, the oil detection element 443 is controlled to retract to the inner position. This prevents the oil detection element 443 from continuously contacting the oil in the collection chamber during rotation, avoids the oil in the collection chamber being mechanically agitated and splashed to other locations, ensures the stability of oil collection in the collection chamber, and also prevents the detection structure from continuously interfering with the oil, which could lead to structural damage.

[0039] Furthermore, the oil detection element 443 is electrically connected to the first cleaning component 230. When the oil detection element 443 detects that the oil level in the collection chamber exceeds the threshold, it controls the first cleaning component 230 to enhance its adsorption capacity from the first adsorption state to the second adsorption state. The specific height threshold needs to be comprehensively judged based on factors such as the oil mist content in the flue gas and the size of the bottom cross section of the collection chamber. Through the above method, a dynamic feedback adjustment process is achieved. By enhancing the adsorption capacity of the first cleaning component 230, the oil mist content in the flue gas that finally enters the exhaust gas emission device 400 is reduced, thereby reducing the oil mist content in the final emitted flue gas and achieving the goal of environmentally friendly emissions.

[0040] It should be noted that the aforementioned oil detection element 443 can select resistance detection to detect oil stains in the collection chamber. Both oil and air are highly insulating media, but their resistance values ​​differ; the resistivity of pure oil is typically 10⁻⁶. 12 -10 14 Ω・cm, the resistivity of air purified through multiple oil mist adsorption processes is typically 10 Ω・cm. 16 -10 18 Ω・cm, utilizing the difference in resistance between the two, a detection circuit is used to detect the difference between oil stains and air.

[0041] In summary, through the above structural design, using static adsorption, dynamic adsorption, complete combustion, re-adsorption, and feedback detection, efficient adsorption and cleaning of flue gas can be achieved, minimizing the oil mist content in the emitted flue gas. Simultaneously, the collection chamber and second cleaning component 440 at the emission end can adsorb and collect the remaining small amount of oil mist. Furthermore, the oil level detection element 443 can detect the oil level in the collection chamber, dynamically adjusting the adsorption capacity of the first cleaning component 230 based on the rate of change in oil level, thus minimizing the final oil mist content in the emitted flue gas. Additionally, the adsorption and cleaning status of the static adsorption cleaning structure can be predicted, prompting staff to promptly inspect and replace the static adsorption cleaning structure, ensuring continuous and efficient adsorption and cleaning of the flue gas by the entire equipment.

[0042] Specifically, the first cleaning component 230 includes a positioning ring 231 fixedly connected to the drive shaft 250. An inclined adsorption main plate 232 is fixed to the side wall of the positioning ring 231. A receiving groove is provided on the side wall of the adsorption main plate 232. An adsorption side plate 233 is slidably connected in the receiving groove. A telescopic rod is provided in the receiving groove to control the telescopic movement of the adsorption side plate 233. When the oil detection element 443 detects that the oil level in the collection chamber exceeds the set threshold, the telescopic rod controls the adsorption side plate 233 to extend to increase the adsorption area and improve the adsorption capacity for oil mist. When the oil detection element 443 does not detect that the oil level in the collection chamber exceeds the set threshold, the telescopic rod and the adsorption side plate 233 are in a contracted state. At this time, the adsorption intensity is low, which can also reduce the resistance to the flow of flue gas and improve the processing capacity of flue gas per unit time, thereby achieving efficient treatment of flue gas.

[0043] The adsorption and capture effect of oil mist in flue gas can be improved by increasing the adsorption area as described above. Similarly, the adsorption and capture effect of oil mist in flue gas can also be improved by increasing the rotation speed of the first cleaning component 230. During the directional rotation of the inclined adsorption main plate 232 and adsorption side plate 233, the oil mist is absorbed and captured by the surface. The oil mist also forms large oil droplets on the surface of the adsorption main plate 232, adsorption side plate 233 and other structures. Finally, under the dual action of gravity and centrifugal force, it is thrown onto the inner wall surface of the adsorption tank 210 and flows down the inner wall of the adsorption tank 210, and is collected at the bottom. A collection container or a collection pipe with built-in valve can be set at the bottom of the adsorption tank 210. When the oil pollution height exceeds the predetermined height, the oil pollution can be collected in one go.

[0044] The second cleaning device 200 is used for dynamic adjustment of adsorption cleaning. The main adsorption cleaning relies on the dynamic adjustment of the first cleaning device 100 and the exhaust gas emission device 400. The purpose of the first cleaning component 230 being designed for intermittent adsorption is that when too much oil accumulates in the exhaust gas emission device 400, the adsorption effect of the second cleaning device 200 is improved through dynamic adjustment, thereby slowing down the adsorption of the exhaust gas emission device 400. This allows the staff enough time to handle the discharged oil, and also greatly reduces the emission of oil mist in the exhaust gas, achieving deep cleaning adsorption of the quenching oil tank flue gas. At the same time, it can also judge the adsorption cleaning status of the relevant static adsorption cleaning structure, so that the staff can replace the relevant structure with weak adsorption cleaning capacity in a timely manner, ensuring a long-term stable cleaning adsorption effect of the oil tank flue gas.

[0045] A position control telescopic rod 260 is provided at the bottom of the adsorption tank 210. The position control telescopic rod 260 can control the state of multiple telescopic rods simultaneously, and control multiple adsorption side plates 233 to extend or retract synchronously, thereby achieving synchronous control and improving control efficiency.

[0046] Specifically, the position control telescopic rod 260 includes a position control housing 261, a position control piston 262 is slidably connected inside the position control housing 261, a position control rod 263 is fixedly connected to the bottom of the position control piston 262, the end of the position control rod 263 passes through the position control housing 261 and is slidably connected thereto, a first control chamber 2601 is formed between the upper end of the position control piston 262 and the position control housing 261, a second position control chamber 2602 is formed between the lower end of the position control piston 262 and the position control housing 261, the first control chamber 2601 communicates with the telescopic rod in the receiving groove, the telescopic rod in the receiving groove is an elastic telescopic rod, and the bottom of the position control rod 263 is externally connected to a power source, which can control the position control rod 263 to move up and down, thereby realizing drive control.

[0047] The first control chamber 2601 is connected to the bottom of the drive shaft 250 via a rotating connecting collar 252. The drive shaft 250 and related structures are hollow inside, which can ensure that the control medium flows normally through both the static and dynamic parts.

[0048] By controlling the position control rod 263 and the position control piston 262 to move upward, the first control chamber 2601 gradually decreases in size, allowing the control medium inside to be squeezed into the telescopic rod to control multiple adsorption side plates 233 to extend outward synchronously, thus achieving synchronous drive control. Similarly, by controlling the position control rod 263 and the position control piston 262 to move downward, the first control chamber 2601 gradually increases in size, allowing the control medium inside multiple telescopic rods to be extracted, thus controlling multiple telescopic rods to drive multiple adsorption side plates 233 to contract synchronously, thus achieving an adaptive drive control process.

[0049] The control medium can be either gas or oil, preferably oil, to avoid the gas being compressed and unable to reach the predetermined expansion distance, thus affecting the efficient absorption of the final oil.

[0050] Specifically, the second cleaning component 440 includes an umbrella-shaped adsorption body 442, a control channel 4421 is provided inside the adsorption body 442, and an oil detection element 443 includes a detection piston 4431 that is slidably and sealingly connected to the control channel 4421. A detection rod 4433 is fixed to the side wall of the detection piston 4431. The detection rod 4433 is connected to the control channel 4421 through an elastic element 4432. A detection probe 4434 is fixed to the end of the detection rod 4433. The detection probe 4434 is located in the collection chamber. By reducing the pressure inside the control channel 4421, the adsorption detection piston 4431 is driven to move the detection probe 4434 inward. By increasing the pressure inside the control channel 4421, the detection piston 4431 is pushed to move the detection probe 4434 outward.

[0051] Under normal conditions, by increasing the pressure inside the control channel 4421, the detection piston 4431, detection probe 4434, and other structures are pushed to the outer position, thereby detecting the oil level in the collection chamber. At this time, the detection probe 4434, located at the outermost position, rotates directionally with the adsorption body 442, thereby detecting the oil level at various locations in the collection chamber. When the oil level at each location is detected to continuously exceed the set threshold, the pressure inside the control channel 4421 is reduced. Under the elastic action of the elastic element 4432, the detection piston 4431, detection probe 4434, and other structures can be pushed to move inward and retract to the inner position to avoid contact with the oil and prevent interference.

[0052] Furthermore, a connecting connector 264 is provided on the side wall of the second position control chamber 2602. The connecting connector 264 is connected to the control channel 4421 through a connecting hose. During the descent of the position control piston 262, the second position control chamber 2602 gradually decreases in size, which can squeeze the control medium in the second position control chamber 2602 into the control channel 4421 to push the detection probe 4434 and other related structures to move outward. During the descent of the position control piston 262, the second position control chamber 2602 gradually increases in size, which can draw the control medium entering the control channel 4421 into the second position control chamber 2602 and control the detection probe 4434 and other related structures to contract.

[0053] Through the above structural design, the adsorption side plate 233 and the detection probe 4434 can be synchronously controlled by a single position-controlled telescopic rod 260. When the detection probe 4434 is in the retracted state, it indicates that there is too much oil accumulation in the collection chamber, and the adsorption side plate 233 needs to be extended to increase the treatment effect on the flue gas. When the detection probe 4434 is in the extended state, it indicates that the oil in the collection chamber has not exceeded the set threshold. At this time, the adsorption side plate 233 is controlled to be in the retracted state to reduce the resistance to the flue gas and improve the treatment efficiency of the flue gas per unit time. Through the above structural design, the extension and retraction state of the position-controlled telescopic rod 260 can be adjusted only according to the detected oil content in the collection chamber, which can realize the adaptive adjustment control of the extension and retraction states of the adsorption side plate 233 and the detection probe 4434. The two are adjusted synchronously, which greatly improves the control efficiency and further improves the detection effect of oil and the treatment effect of oil mist in the flue gas.

[0054] Furthermore, it is preferable to configure the control channel 4421 and the oil detection element 443 as two sets, with the detection probes 4434 of the two sets of oil detection elements 443 at different heights. The two sets of detection probes 4434 at different heights can detect oil contaminants at different heights. When the lower-positioned detection probe 4434 of the first set detects oil contaminants at a lower height, it sends a signal to control the adsorption side plate 233 to extend and enhance the treatment of flue gas. Simultaneously, the lower-positioned detection probe 4434... When probe 4434 retracts to its deepest position, the position of the first set of detection probes 4434 is higher than that of the second set of detection probes 4434. Even after the adsorption side plate 233 extends, the oil mist in the exhaust gas still cannot be effectively treated. This indicates that the adsorption life of the static adsorption structure has reached its limit. At this time, the oil mist content in the flue gas continues to rise, forming more oil stains in the collection chamber. The continuous rise of the oil level is detected by the second set of detection probes 4434, triggering an alarm signal and prompting staff to immediately inspect the static adsorption structure to prevent continuous oil mist emission.

[0055] The dual-probe design allows for the detection of oil mist in flue gas based on its short-term or sustained rise. When oil levels rise continuously in the collection chamber, it promptly alerts staff to inspect and replace the relevant static adsorption structure, ensuring environmentally friendly emissions. The dual-probe design, compared to a single probe retracting to different positions, provides more accurate detection and avoids the impact of oil contamination from the first probe affecting subsequent tests. Furthermore, the centrifugal force of the probes during prolonged rapid rotation dissipates oil from their surfaces, preventing long-term oil residue from affecting subsequent detections.

[0056] Furthermore, a first control airbag 265 and a second control airbag 266 are disposed within the second control chamber 2602. The first control airbag 265 and the second control airbag 266 are arranged in a stacked manner. Both the first control airbag 265 and the second control airbag 266 have expansion elasticity, and the expansion elasticity coefficients of the first control airbag 265 and the second control airbag 266 are different. During the compression process, the second control airbag 266 is compressed before the first control airbag 265, and during the expansion process, the first control airbag 265 is expanded before the second control airbag 266. The first control airbag 265 is placed within the first set of lower-positioned detection probes 4434. The control channel 4421 is connected. During the upward movement of the position control piston 262, the first control airbag 265 first expands to extract the control oil in the control channel 4421 corresponding to the first set of lower-position detection probes 4434, and controls the first set of detection probes 4434 to retract to the predetermined position. During the upward movement of the position control piston 262, the first control airbag 265 stops expanding, and the second control airbag 266 begins to expand under its own elasticity, thereby extracting the control oil in the control channel 4421 corresponding to the second set of detection probes 4434, and controlling the second set of detection probes 4434 to retract, so as to avoid contact with the oil stains in the collection chamber.

[0057] The first control airbag 265 and the second control airbag 266 mentioned above can be connected to the corresponding control channel 4421 via separate connecting pipes. A double-layer sleeve rotating connector structure design can be adopted in the positioning shaft 441. The innermost layer and the bottom of the double-layer sleeve are connected to different control channels 4421 respectively, and the innermost layer and the top of the double-layer sleeve are connected to different separate connecting pipes through rotating sealing connectors to realize the conduction control of the control medium.

[0058] Specifically, the second cleaning component 440 also includes a hollow positioning shaft 441. The bottom of the positioning shaft 441 is fixed to the adsorption body 442 and communicates with the control channel 4421. Multiple guide grooves 4422 are opened on the surface of the adsorption body 442. The guide grooves 4422 are through and extend to the bottom edge. The positioning shaft 441 can be driven and controlled by a power source to control the positioning shaft 441 and the adsorption body 442 below to rotate in a directional manner. During the directional rotation, the oil at the bottom of the adsorption body 442 is thrown into the collection tank for centralized collection. It should be noted that the detection probe 4434 is located at a predetermined position on the upper end of the adsorption body 442, and there is a gap between the two. The oil droplets thrown into the collection tank by the adsorption body 442 will not affect the normal detection of the detection probe 4434.

[0059] The aforementioned guide channel 4422 can also play a guiding role, enabling normal and efficient collection of oil droplets.

[0060] Inside the adsorption tank 210, a laser detection element 220 is also provided. At least two sets of laser detection elements 220 are provided, and the two sets of laser detection elements 220 are located on both sides of the first cleaning component 230. The laser detection element 220 can detect the oil mist content in the flue gas at different heights inside the adsorption tank 210. Utilizing the principle of optical diffuse reflection, when the oil mist content in the flue gas is high, the optical diffuse reflection is enhanced, and the optical signal received by the optical receiver changes, thereby realizing the detection of the oil mist content.

[0061] The first cleaning component 230 can be selected as two sets arranged at intervals, and the laser detection element 220 can be selected as three sets arranged at intervals, namely detector 1 221, detector 222 and detector 3 223 from top to bottom. The smoke content at different locations can be detected by the spaced detection elements to determine the instantaneous smoke content and the ability of the first cleaning component 230 to capture oil mist, so as to provide relevant data for staff reference. A protective cover that can be cleaned regularly can be set on the outside of the laser detection element 220 to ensure the stability of the long-term detection effect of the laser detection element 220. The above structure is the prior art and will not be described in detail here.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
