Abstract
Description
Technical Field
[0001] This utility model relates to the field of cleaning furnace technology, specifically a triethylene glycol cleaning furnace with waste gas treatment. Background Technology
[0002] Triethylene glycol cleaning furnaces are specialized equipment used to clean carbon deposits and residues in polymer processing equipment. They utilize triethylene glycol as a cleaning medium, introducing triethylene glycol-containing vapor or liquid into the equipment to be cleaned under high temperature conditions. Triethylene glycol has excellent dissolving power, especially for polymers, greases, and other organic substances.
[0003] Utility model patent application CN202022426260.9 discloses a triethylene glycol cleaning furnace, including a furnace body. Insulation plates are installed on both sides of the furnace body, and a fixing block is welded to the upper part of the insulation plates. A stud is installed on the top of the fixing block, and a first servo motor is movably connected to the stud. A limit plate is installed on the top of the stud. The beneficial effect of this utility model is that by using a cleaning basket, a transmission rod, a drive gear, and a driven gear, a second servo motor is started. The second servo motor drives the drive gear to rotate, and the drive gear and driven gear cooperate to move the transmission rod up and down, thereby moving the cleaning basket and the components to be cleaned up and down. This allows the triethylene glycol solution to fully contact the chemical fiber components, resulting in a better cleaning effect.
[0004] However, this technical solution lacks waste gas treatment capabilities. Untreated waste gas emitted directly may contain incompletely decomposed or volatilized triethylene glycol and other organic compounds. If these substances enter the atmosphere, they will pollute the air, have a negative impact on the environment, and further exacerbate environmental pollution. Furthermore, if the harmful components in the waste gas are inhaled by operators, they may have adverse effects on human health. Utility Model Content
[0005] The present invention addresses the shortcomings of the prior art by providing a triethylene glycol cleaning furnace with exhaust gas treatment. This solves the problems that existing untreated exhaust gases may contain incompletely decomposed or volatilized triethylene glycol and other organic compounds, which, if released into the atmosphere, will pollute the air and have a negative impact on the environment, further exacerbating environmental pollution. Additionally, if harmful components in the exhaust gas are inhaled by operators, they may have adverse effects on human health.
[0006] Specifically, the water mist sprayed by the treatment components comes into contact with the exhaust gas. Ethanol is a commonly used organic solvent that is completely miscible with water and can also be miscible with triethylene glycol. This allows the triethylene glycol in the exhaust gas to be dissolved and separated, preventing it from being released into the air and polluting the environment. It also prevents the human body from inhaling it and harming their health, thus providing excellent protection for both the air environment and the human body.
[0007] The technical problem to be solved by this utility model is achieved by the following technical solution: A triethylene glycol cleaning furnace with waste gas treatment includes: a cleaning furnace body, a cleaning chamber, a cleaning basket, and a treatment component. The cleaning furnace body has a cleaning chamber inside, and a cleaning basket is provided inside the cleaning chamber. The cleaning furnace body has a treatment component at its outer end. The treatment component includes: a waste gas treatment box, a waste discharge pipe, a gas outlet, a liquid storage tank, a liquid pump, a delivery pipe, and a spray head.
[0008] In a further preferred embodiment, a waste gas treatment box is provided at the outer end of the main body of the cleaning furnace. A waste discharge pipe is installed between the waste gas treatment box and the main body of the cleaning furnace. Multiple air outlets are opened on the waste discharge pipe. A liquid storage tank is installed on the top of the waste gas treatment box. A liquid pump is installed at the bottom of the inside of the liquid storage tank. A delivery pipe connected to the liquid pump is installed at the outer end of the liquid storage tank. The delivery pipe runs through the inside of the waste gas treatment box. Multiple spray heads are installed at the bottom of the delivery pipe.
[0009] In a further preferred embodiment, heating blocks are installed on both sides of the inside of the cleaning chamber, a partition net is installed on the outer periphery of the cleaning basket, and handles are installed on both sides of the top of the cleaning basket.
[0010] In a further preferred embodiment, a sealing cover is rotatably connected to the top of the cleaning chamber via a hinge, and a handle is installed on one side of the top of the sealing cover.
[0011] In a further preferred embodiment, a fixing frame is installed inside the cleaning chamber, and multiple support blocks are installed on the top of the fixing frame.
[0012] In a further preferred embodiment, a drain pipe a is installed at the bottom of the main body of the cleaning furnace, a solenoid valve is installed on the drain pipe a, and a waste discharge pipe is installed at the bottom of the waste gas treatment box.
[0013] In a further preferred embodiment, an exhaust pipe is installed on one side of the top of the waste gas treatment box, and an observation window is provided on the outside of the liquid storage tank.
[0014] Compared with the technical content disclosed in the prior art document (CN202022426260.9) "A Triethylene Glycol Cleaning Furnace", the beneficial effects of this utility model are: (1) By using the waste gas treatment box, waste pipe, gas outlet, liquid storage tank, liquid pump, delivery pipe and spray head together, the sprayed water mist can come into contact with the waste gas. Ethanol is a commonly used organic solvent that is completely miscible with water and can be miscible with triethylene glycol. In this way, the triethylene glycol in the waste gas can be dissolved and separated to prevent it from being discharged into the air and polluting the environment. It can also prevent the human body from inhaling it and harming their health. It provides good protection for both the air environment and the human body. Attached Figure Description

[0026] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the present utility model will be described in detail below with reference to the accompanying drawings and preferred embodiments. It should be noted that the terms "left," "right," "upper," "lower," "top," "bottom," "one side," "provided with," "installed with," "connected with," "top end," "bottom end," "provided with," "open with," "fixed connection," "movable connection," "threaded connection," "clamping," "sleeving," "outer end," "inner end," "external," and "internal" in the following description are only for ease of understanding and description, and are not intended to indicate or imply that the components or structures referred to must have a specific orientation or installation method, and therefore should not be construed as limitations on this utility model.
[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0028] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments. Example
[0029] like Figures 1-5 As shown, a triethylene glycol cleaning furnace with waste gas treatment includes: a cleaning furnace body 1, a cleaning chamber 101, a cleaning basket 102, and a treatment component. The cleaning furnace body 1 has a cleaning chamber 101 inside, and a cleaning basket 102 inside the cleaning chamber 101. The cleaning furnace body 1 has a treatment component at its outer end. The treatment component includes: a waste gas treatment box 3, a waste discharge pipe 301, a gas outlet 302, a liquid storage tank 303, a liquid pump 304, a delivery pipe 305, and a spray head 306.
[0030] Heating blocks 103 are installed on both sides of the inside of the cleaning chamber 101, and a partition net 104 is installed on the outer periphery of the cleaning basket 102. Handles 105 are installed on both sides of the top of the cleaning basket 102. A sealing cover plate 2 is rotatably connected to the top of the cleaning chamber 101 via a hinge, and a handle 201 is installed on one side of the top of the sealing cover plate 2.
[0031] When cleaning parts, place the parts inside the cleaning basket 102, then grasp the handle 105 to lift the cleaning basket 102 and place it into the cleaning chamber 101. Add triethylene glycol solution to the cleaning chamber 101, so that the triethylene glycol solution submerges the cleaning basket 102. Make the handle 105 protrude from the surface of the triethylene glycol solution, so that the cleaning basket 102 can be lifted out of the cleaning chamber 101 by grasping the handle 105.
[0032] After placing the cleaning basket 102 and the parts into the cleaning chamber 101 and adding the triethylene glycol solution, flip the sealing cover 2 to cover the cleaning chamber 101 to seal it and prevent heat loss during the heating of the triethylene glycol solution. At this time, start the heating block 103. After the heating block 103 starts working, it transfers heat to the inside of the cleaning chamber 101, causing the triethylene glycol solution to heat up and have good dissolving ability, which can quickly dissolve and clean the grease on the parts.
[0033] The cleaning chamber 101 is equipped with a fixing frame 4, and multiple support blocks 401 are mounted on the top of the fixing frame 4. When the cleaning basket 102 is placed inside the cleaning chamber 101, the fixing frame 4 and the multiple support blocks 401 can support and place the cleaning basket 102 (e.g., ...). Figure 2 As shown in the figure, ensuring that the cleaning basket 102 and the parts are in full contact with the triethylene glycol solution inside the cleaning chamber 101 helps to improve the cleaning effect on the parts.
[0034] The main body 1 of the cleaning furnace is equipped with a waste gas treatment box 3 at its outer end. A waste discharge pipe 301 is installed between the waste gas treatment box 3 and the main body 1 of the cleaning furnace. Multiple air outlets 302 are opened on the waste discharge pipe 301. A liquid storage tank 303 is installed on the top of the waste gas treatment box 3. A liquid pump 304 is installed at the bottom of the inside of the liquid storage tank 303. A conveying pipe 305 connected to the liquid pump 304 is installed at the outer end of the liquid storage tank 303. The conveying pipe 305 runs through the inside of the waste gas treatment box 3. Multiple spray heads 306 are installed at the bottom of the conveying pipe 305.
[0035] During the process of heating and cleaning parts with a triethylene glycol solution inside the cleaning chamber 101, the triethylene glycol solution generates harmful triethylene glycol waste gas after heating. This waste gas can be introduced into the waste gas treatment box 3 from the waste pipe 301 and discharged into the waste gas treatment box 3 from multiple vent holes 302. Since multiple spray heads 306 are located at the top of the waste pipe 301 and the vent holes 302 (e.g., ...), the multiple spray heads 306 are located at the top of the waste pipe 301 and the vent holes 302 (e.g., ...). Figure 2 As shown in the diagram, the storage tank 303 is equipped with a liquid addition pipe and a sealing cap at the top. The sealing cap is opened, and a solution of water and ethanol organic solvent is added into the storage tank 303 through the liquid addition pipe. The sealing cap is then tightened back onto the top of the liquid addition pipe. At this time, the liquid pump 304 is started to extract the water and ethanol mixture, which is then discharged through the delivery pipe 305 into multiple spray heads 306. Water mist is sprayed from the multiple spray heads 306 onto the waste discharge pipe 301 and the air outlet 302, allowing the sprayed water mist to contact the waste gas. Ethanol is a commonly used organic solvent that is completely miscible with water and can also be miscible with triethylene glycol. This allows the triethylene glycol in the waste gas to be dissolved and separated, preventing it from being released into the air and polluting the environment. It also avoids inhalation by humans, thus providing excellent protection for both the air environment and human health.
[0036] The exhaust gas treatment box 3 has an exhaust pipe 6 installed on one side of its top, and an observation window 601 is provided on the outside of the liquid storage tank 303. After the harmful triethylene glycol waste gas is dissolved and separated inside the exhaust gas treatment box 3, the clean and harmless gas inside the exhaust gas treatment box 3 can be discharged from the exhaust pipe 6. During the use of the liquid storage tank 303, the liquid level inside the liquid storage tank 303 can be observed through the observation window 601 so that it can be added in time for backup, ensuring that the exhaust gas treatment is carried out normally.
[0037] The bottom of the cleaning furnace body 1 is equipped with a drain pipe a5, and a solenoid valve 501 is installed on the drain pipe a5. The bottom of the waste gas treatment box 3 is equipped with a waste discharge pipe 502.
[0038] The used triethylene glycol solution inside the cleaning chamber 101 can be discharged through the drain pipe a5. That is, the solenoid valve 501 is activated and opened. The drain pipe a5 is connected to the inside of the cleaning chamber 101, and the triethylene glycol solution is discharged from the drain pipe a5 to the outside of the cleaning furnace body 1. The waste liquid used to treat the waste gas inside the waste gas treatment box 3 can also be discharged through the waste discharge pipe 502. When the existing drain pipe a5 and waste discharge pipe 502 are in use, a sewage pipe is installed at the bottom and the sewage pipe is connected to the sewage tank. This is common knowledge. The discharged waste liquid can be uniformly discharged into the sewage tank for purification treatment to prevent the waste liquid from polluting the water environment.
[0039] When the exhaust gas treatment box 3 is in use, a control box is installed on the outside of the exhaust gas treatment box 3, and a temperature sensor is installed inside the cleaning chamber 101. The control box is equipped with multiple control buttons and a display screen. When the heating block 103, liquid pump 304, solenoid valve 501 and temperature sensor are in use, the power of the cleaning furnace body 1 and the exhaust gas treatment box 3 is provided by an external power source. The control box is electrically connected to the heating block 103, liquid pump 304, solenoid valve 501 and temperature sensor respectively. The control box can control the heating block 103, liquid pump 304, solenoid valve 501 and temperature sensor to start and stop. The display screen can display the temperature value of the triethylene glycol solution heated inside the cleaning chamber 101, so that the staff can know it. The control program involved in this utility model can be implemented by those skilled in the art based on the same or similar principles in the prior art. This part is not the innovation of this utility model.
[0040] Working principle: When cleaning parts, place the parts inside the cleaning basket 102, then grasp the handle 105 to lift the cleaning basket 102 and place it into the cleaning chamber 101. Add triethylene glycol solution to the cleaning chamber 101, ensuring the triethylene glycol solution submerges the cleaning basket 102. The handle 105 should protrude above the surface of the triethylene glycol solution for easy gripping. After placing the cleaning basket 102 and parts into the cleaning chamber 101 and adding the triethylene glycol solution, flip the sealing cover 2 to seal the cleaning chamber 101, preventing heat loss during the heating of the triethylene glycol solution. At this point, activate the heating block 103. The heating block 103 transfers heat to the cleaning chamber 101, raising the temperature of the triethylene glycol solution and giving it excellent dissolving power to quickly dissolve and clean the grease on the parts.
[0041] During the process of heating and cleaning parts with a triethylene glycol solution inside the cleaning chamber 101, the triethylene glycol solution generates harmful triethylene glycol waste gas after heating. This waste gas can be introduced into the waste gas treatment box 3 from the waste pipe 301 and discharged into the waste gas treatment box 3 from multiple vent holes 302. Since multiple spray heads 306 are located at the top of the waste pipe 301 and the vent holes 302 (e.g., ...), the multiple spray heads 306 are located at the top of the waste pipe 301 and the vent holes 302 (e.g., ...). Figure 2 As shown in the diagram, the storage tank 303 is equipped with a liquid addition pipe and a sealing cap at the top. The sealing cap is opened, and a solution of water and ethanol organic solvent is added into the storage tank 303 through the liquid addition pipe. The sealing cap is then tightened back onto the top of the liquid addition pipe. At this time, the liquid pump 304 is started to extract the water and ethanol mixture, which is then discharged through the delivery pipe 305 into multiple spray heads 306. Water mist is sprayed from the multiple spray heads 306 onto the waste discharge pipe 301 and the air outlet 302, allowing the sprayed water mist to contact the waste gas. Ethanol is a commonly used organic solvent that is completely miscible with water and can also be miscible with triethylene glycol. This allows the triethylene glycol in the waste gas to be dissolved and separated, preventing it from being released into the air and polluting the environment. It also avoids inhalation by humans, thus providing excellent protection for both the air environment and human health.
