Description

Technical Field

[0001] The invention belongs to the technical field of brominated epoxy resin production accessories, and in particular relates to a waste gas treatment device and method for brominated epoxy resin. Background Art

[0002] In modern industrial production, with the widespread application of brominated epoxy resin, the pollution problem of organic waste gas generated in its production process has become increasingly prominent. The main component of organic waste gas is toluene, which not only causes certain pollution to the environment, but also poses a potential threat to human health.

[0003] Toluene is a volatile organic compound that is commonly found in the synthesis of brominated epoxy resins. Its high volatility and flammable and explosive properties make it harmful to the surrounding air quality and ecosystem once released into the environment.

[0004] In addition, long-term exposure to toluene may cause a series of health problems, including headaches, dizziness, respiratory diseases and even neurological damage.

[0005] In addition to toluene, a series of other organic waste gas pollutants are also produced, which also have a negative impact on the environment. These include but are not limited to: In addition to toluene, benzene may also be released during the production process. Benzene is a volatile organic compound that is harmful to the environment and human health. Long-term exposure may cause respiratory problems and potential cancer risks.

[0006] In the process of preparing brominated epoxy resins, organic chlorine compounds such as chlorobenzene and bromobenzene are sometimes produced. They are odorous substances that cause odor pollution to the environment and may have an impact on the ecosystem.

[0007] Organic solvents used in the production process, such as acetone and xylene, will evaporate into organic waste gas, causing pollution to the atmospheric environment and may also cause harm to human health.

[0008] Under high temperature conditions, nitrogen oxides may be produced during the production process. These gases are one of the atmospheric pollutants and together with sulfur dioxide, carbon monoxide, etc., constitute typical industrial waste gas.

[0009] In order to reduce the impact of waste gas emissions on the environment and human health, there is an urgent need to develop effective waste gas purification devices and methods to treat toluene waste gas pollution generated in the production of brominated epoxy resins. By treating toluene waste gas, it is ensured that the emitted waste gas meets environmental protection standards to protect the surrounding environment and the health and safety of personnel.

[0010] In summary, how to provide a waste gas treatment device and method that can effectively purify waste gas including toluene generated in the production of brominated epoxy resin is a technical problem that urgently needs to be solved. Summary of the invention

[0013] Furthermore, the activated carbon sampler has upper and lower openings, wherein a cover plate that can be opened and closed is provided at the upper opening, and the activated carbon sample can enter the activated carbon sampler through the open upper opening.

[0014] Furthermore, the activated carbon sampler is arranged on the side wall of the activated carbon bin near the bottom, and the bottom of the activated carbon sampler is not in contact with the bottom of the activated carbon bin; The activated carbon sampler is provided with an auxiliary device, and the auxiliary device can drive the activated carbon particles around the activated carbon sampler to move.

[0015] Furthermore, a sampling component is provided on the activated carbon sampler, and the sampling component is used to collect and transfer the activated carbon sample into the activated carbon sampler having a containing space.

[0016] Furthermore, the sampling assembly includes a hollow extraction tube, which can be selectively connected to the storage structure. In the connected state, the extraction tube can generate inward suction to suck the activated carbon in the activated carbon bin into the extraction tube and transfer it to the activated carbon sampler.

[0017] Furthermore, the extraction tube is configured to be retractable and / or the front end thereof is rotatable.

[0018] Furthermore, a heating sealing plate that can be opened and closed is provided at the lower opening of the activated carbon sampler; the heating sealing plate can close the lower opening of the activated carbon sampler and heat the activated carbon particles in the storage component, or the heating sealing plate can be opened to allow the activated carbon in the activated carbon sampler to fall through the open lower opening.

[0019] Furthermore, the pressure-triggered component is arranged on the cover plate of the upper opening of the aforementioned activated carbon sampler, and / or on the heating sealing plate of the lower opening.

[0020] The present invention provides a method for treating organic waste gas using the waste gas treatment device for brominated epoxy resin described in any one of the above, the method comprising the following steps: The organic waste gas is condensed through a condensation system to precipitate waste liquid; The organic waste gas is adsorbed by the activated carbon placed in the activated carbon bin; during the adsorption process, the activity of the activated carbon is tested by the activated carbon activity verification structure; Based on the detection results, the desorption operation in the activated carbon bin is started accordingly, so that the activated carbon desorbs the organic waste gas.

[0021] Furthermore, the activated carbon activity verification structure includes at least two activated carbon samplers; the number of pressure-triggered components entering the trigger state is monitored and counted; when the number ratio is not lower than a preset threshold, the desorption operation of the activated carbon bin where the activated carbon activity verification structure is located is triggered accordingly.

[0022] Due to the adoption of the above technical solution, the present invention has the following advantages and positive effects compared with the prior art, as an example: Through the condensation system and activated carbon adsorption, the organic waste gas generated in the production process of brominated epoxy resin can be effectively treated to reduce pollution to the environment.

[0023] By setting up an activated carbon activity verification structure in the activated carbon bin, the activity state of the activated carbon can be detected and determined.

DETAILED DESCRIPTION

[0036] The technical solution disclosed in the present invention is described in detail below in conjunction with specific embodiments.

[0037] Techniques and methods known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques and methods should be considered part of the specification. In all examples shown and discussed herein, any specific value should be interpreted as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values.

[0038] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0039] The present invention provides a waste gas treatment device 100 for brominated epoxy resin, comprising a condensation system, such as Figure 6 shown.

[0040] The condensation system is used to condense the organic waste gas generated in the production process of brominated epoxy resin, and includes a first condensation bin 110, a second condensation bin 120 and / or a third condensation bin 130 arranged in sequence along the direction of travel of the organic waste gas.

[0041] First, the organic waste gas enters the first condensation chamber 110 and is cooled to condense part of the waste liquid.

[0042] Then the organic waste gas enters the second condensation chamber 120 to be cooled again, and a part of the waste liquid is precipitated; to ensure the deep cold treatment effect, the waste gas after two condensations enters the third condensation chamber 130 to be cooled to a depth for the third time to precipitate the residual trace waste liquid.

[0043] At least one of the second condensation bin 120 and / or the third condensation bin 130 is provided with an activated carbon bin 200 .

[0044] The activated carbon bin is connected to the second condensation bin 120 and / or the third condensation bin 130 via an air intake pipe 150 .

[0045] The activated carbon bin 200 contains activated carbon particles, which can adsorb the uncondensed organic waste gas in the second condensation bin 120 and / or the third condensation bin 130 through the activated carbon.

[0046] Each of the activated carbon particles is an independent individual. Figure 1A Taking the embodiment in as an example, when a certain number of activated carbon particles are placed in the activated carbon bin 200, the activated carbon particles 10 are piled up at the bottom of the activated carbon bin 200, overlapping and contacting each other to form a certain height.

[0047] Its adsorption efficiency depends on the pore structure and surface area of ​​the activated carbon and the nature of the adsorbed substances. When the activated carbon particles come into contact with organic pollutants in the exhaust gas, these substances are adsorbed on the surface and pores of the activated carbon.

[0048] As the adsorption process progresses, the adsorption sites of activated carbon particles gradually become saturated, and the space on the surface and in the pores of activated carbon is occupied by organic pollutants, making it difficult for new exhaust gas molecules to be adsorbed. In this case, the adsorption efficiency of activated carbon will gradually decrease until it reaches a saturated state and can no longer effectively adsorb pollutants in the exhaust gas.

[0049] An activated carbon activity verification structure 300 is disposed in the activated carbon bin 200 .

[0050] The activated carbon activity verification structure 300 includes an activated carbon sampler 310, such as Figure 1A and 1B shown.

[0051] The shape of the activated carbon sampler 310 is not limited, as long as it has a certain storage space.

[0052] As one of the typical implementations, the activated carbon sampler 310 has upper and lower openings 312 , wherein an openable and closable cover plate 320 is provided at the upper opening 311 , and the activated carbon sample can enter the activated carbon sampler 310 through the opened upper opening 311 .

[0053] The cover plate 320 and the upper opening 311 are connected by rotation, sliding, threading, magnetic connection, etc., so that the cover plate 320 and the upper opening 311 can move relative to each other, thereby realizing the opening and closing of the cover plate 320.

[0054] As one of the typical implementation methods, Figure 2A and 2B As shown, the activated carbon sampler 310 is disposed on the side wall of the activated carbon bin 200 near the bottom, and the bottom of the activated carbon sampler 310 does not contact the bottom of the activated carbon bin 200, and there is a space between the two.

[0055] When activated carbon particles are stacked at the bottom of the activated carbon bin 200 , the activated carbon sampler 310 is surrounded and buried in the activated carbon particles. When the upper opening 311 is in a closed state, the activated carbon particles cannot enter the activated carbon sampler 310 .

[0056] When the cover 320 is opened, the activated carbon particles accumulated above the activated carbon sampler 310 enter the activated carbon sampler 310 through the opened upper opening 311, and the positions of some activated carbon particles in the activated carbon bin 200 are vacant, which will cause the activated carbon particles located around these activated carbon particles to move and automatically fill these vacancies. This position movement phenomenon can improve the uniformity of the collected activated carbon samples.

[0057] When the cover 320 is open, the activated carbon particles gradually fill the inside of the activated carbon sampler 310 until the required sampling amount is reached. After the cover 320 is opened for a preset time, it is closed to prevent the activated carbon particles from further entering. In this way, the activated carbon sampler 310 completes the sampling step of the activated carbon in the activated carbon bin 200.

[0058] The activated carbon particle sample leaves the activated carbon sampler 310 through the lower opening 312 in an open state and enters the activated carbon particles stacked at the bottom of the activated carbon bin 200 .

[0059] In the specific implementation, if the activated carbon sampler 310 is surrounded by activated carbon particles, there is no extra space for the activated carbon particles coming out of the lower opening 312, which may lead to the activated carbon sampling situation where the activated carbon sample cannot leave. In order to ensure that the activated carbon particle sample can smoothly enter the activated carbon particles in the activated carbon bin 200, an auxiliary device 360 ​​is also provided on the activated carbon bin 200, and the auxiliary device 360 ​​can assist the activated carbon sampler 310 in the process of discharging the activated carbon sample.

[0060] The auxiliary device 360 ​​includes an airflow auxiliary component. An airflow guide device is set on the side or bottom of the activated carbon sampler 310. By spraying airflow to the activated carbon particles around the activated carbon sampler 310, the activated carbon particles are prompted to move and make space, thereby assisting the activated carbon sample particles to fall smoothly from the lower opening 312.

[0061] The auxiliary device 360 ​​includes a vibration auxiliary component. The vibration device is installed at the bottom or side of the activated carbon sampler 310 to cause the activated carbon particles in the activated carbon bin 200 to move through vibration.

[0062] Alternatively, the auxiliary device 360 ​​includes a tiltable bracket or base provided on the activated carbon sampler 310, and the tilt angle of the activated carbon sampler 310 is finely adjusted as needed to assist in the discharge of the activated carbon sample.

[0063] During this process, the activated carbon particles leaving the activated carbon sampler 310 interact with the activated carbon particles at the bottom of the activated carbon bin 200, causing slight adjustments and movements in the positions of the particles at the bottom. This continuous change in position reduces the possibility of collecting duplicate activated carbon samples in a single sampling, thereby improving the accuracy and representativeness of the sampling.

[0064] In another embodiment, if Figure 1A , 1B and Figure 3 As shown, the activated carbon sampler 310 is provided with a sampling assembly, and the sampling assembly is used to collect and transfer the activated carbon sample into the activated carbon sampler 310 having a containing space.

[0065] As a typical embodiment, the sampling assembly includes a hollow extraction tube 350, wherein the extraction tube 350 is provided with a gate, for example, so as to selectively communicate with the storage structure.

[0066] The front end of the extraction tube 350 is configured to be able to touch the bottom of the activated carbon bin 200, so as to be able to suck away the activated carbon particles at the bottom. In this embodiment, two sampling assemblies are provided on both sides of the activated carbon sampler 310 to collect the activated carbon particles at the bottom of the activated carbon bin 200 on both sides.

[0067] In the connected state, the extraction tube 350 can generate inward suction, which can be achieved by a vacuum pump, a fan or other exhaust equipment, to generate airflow or negative pressure in the tube, so as to suck the activated carbon in the activated carbon bin 200 into the extraction tube 350 and transfer it to the activated carbon sampler 310.

[0068] Furthermore, if Figure 3 As shown, the extraction tube 350 is configured to be telescopic, for example, a telescopic portion 351 is provided on the extraction tube 350 .

[0069] The extraction tube 350 can extend into the piled activated carbon particles by being extended, or can extend out of the piled activated carbon particles by being shortened, so as to contact the activated carbon particles at different heights in the pile.

[0070] And / or, the front end of the extraction tube 350 can rotate, for example, a rotation shaft 352 is provided between the front end and the non-front end of the extraction tube 350 .

[0071] After the extraction tube 350 extends into the accumulated activated carbon particles, the front end rotates to contact and absorb the activated carbon particles at different positions.

[0072] In addition, the rotation of the front end of the extraction tube can also stir the activated carbon particles, causing the position of the activated carbon particles to change.

[0073] Of course, the method is not limited to the extraction tube 350 mentioned above, and samples can also be collected by sampling components of other structures, such as a mechanical arm or a sampling structure such as a conveyor belt.

[0074] After the step of collecting samples is completed, the cover plate 320 is closed and the carbon sampler is in a closed state.

[0075] Preferably, a heating sealing plate 340 that can be opened and closed is provided at the lower opening 312 of the activated carbon sampler 310. Figure 1A , Figure 2A and Figure 3 shown.

[0076] The heating sealing plate 340 is equivalent to an openable and closable cover plate 320 similar to the upper opening 311 of the activated carbon sampler 310 , and can close or open the lower opening 312 of the activated carbon sampler 310 .

[0077] After the heating sealing plate 340 closes the lower opening 312 of the activated carbon sampler 310 , the activated carbon particles in the activated carbon sampler 310 can be heated.

[0078] At this time, the upper and lower openings 312 of the activated carbon sampler 310 are both in a closed state. After heating, the activated carbon particles desorb gas, the amount of released gas, and the internal temperature will cause the gas pressure in the activated carbon sampler 310 to change.

[0079] The number of activated carbon samples that the activated carbon sampler 310 can accommodate corresponds to the size of the internal content space of the activated carbon sampler 310, that is, the number of activated carbon samples is relatively fixed.

[0080] In the activated carbon adsorption process, when the activated carbon particles are not fully saturated, they still have adsorption capacity, but have not yet reached the limit state. In this case, the amount of gas released by the activated carbon particles after heating may be relatively small, because there are still adsorption sites available inside the particles.

[0081] When activated carbon particles are saturated or close to saturation, their adsorption capacity reaches its limit. At this time, heating the activated carbon particles will cause the adsorbed gas to desorb from the particles, resulting in an increase in the amount of gas discharged. The temperature change after heating will also affect the desorption rate of the gas. Generally, the higher the temperature, the faster the desorption rate.

[0082] Therefore, when the activated carbon particles are saturated or close to saturation, the amount of gas discharged after heating may be larger, because the activated carbon particles have adsorbed a large amount of gas in the saturated state, and these gases will be released after heating.

[0083] Therefore, the activity state of the activated carbon particles can be inferred by monitoring the changes in the internal air pressure of the activated carbon sampler 310. If the internal air pressure of the activated carbon sampler 310 increases significantly after heating, and this change conforms to the preset air pressure change pattern under the saturated state, it can be reasonably inferred that the activated carbon particles are saturated or close to saturation.

[0084] Preferably, if Figure 1A , Figure 2A and Figure 3 As shown, the activated carbon sampler 310 is provided with a pressure-triggered component 330, which is used to enter a trigger state when the air pressure in the activated carbon sampler 310 reaches a preset threshold value, thereby triggering the heating structure (not shown in the figure) provided in the activated carbon bin 200 to perform a heating and desorption operation on the activated carbon.

[0085] When the number of activated carbon samples is relatively fixed, an estimate of the preset threshold is obtained by analyzing factors such as the adsorption saturation state of the activated carbon particles, the amount of gas released after heating, the heating temperature, and design parameters such as the internal volume of the activated carbon sampler 310.

[0086] The pressure-triggered assembly 330 includes a sensor for measuring the internal air pressure of the activated carbon sampler 310 .

[0087] The controller receives the signal from the sensor and is used to send a signal to the heating structure 210 in the activated carbon bin 200 when the sensor detects that the air pressure reaches a preset threshold, triggering the heating structure 210 to heat the activated carbon in the activated carbon bin 200 to desorb the gas.

[0088] Optionally, the pressure-triggered component 330 is disposed on the cover plate 320 of the upper opening 311 of the aforementioned activated carbon sampler 310 and / or on the heating sealing plate 340 of the lower opening 312, as shown in the figure.

[0089] The advantage of this arrangement is that both the cover 320 and the heating seal 340 can change their positions relative to the activated carbon sampler 310. Therefore, it is easier to maintain or replace the pressure-triggered component 330 later when it is arranged on the cover 320 and the heating seal 340 than when it is arranged inside the activated carbon sampler 310.

[0090] The present invention provides a method for treating organic waste gas using the waste gas treatment device 100 for brominated epoxy resin described in any one of the above, the method comprising the following steps: The organic waste gas is condensed through a condensation system to precipitate waste liquid.

[0091] The organic waste gas is adsorbed by the activated carbon placed in the activated carbon bin 200; during the adsorption process, the activity of the activated carbon is detected by the activated carbon activity verification structure 300.

[0092] Based on the detection result, the desorption operation in the activated carbon bin 200 is started accordingly, so that the activated carbon desorbs the organic waste gas.

[0093] Optionally, an exhaust component is provided to transfer the organic waste gas desorbed by the activated carbon during the desorption operation into the aforementioned condensation system to enter the next cycle treatment process.

[0094] In a specific implementation, the activated carbon particles in the activated carbon bin 200 may include three states at the same time, part of which is in an unsaturated state, part of which is in a near-saturated state, and part of which is in a saturated state.

[0095] In such a case, verification of activated carbon activity by a single activated carbon activity verification structure 300 may not be representative.

[0096] Therefore, further, the activated carbon activity verification structure 300 includes at least two activated carbon samplers 310 .

[0097] like Figure 4 As shown, when multiple activated carbon samplers 310 are provided, the multiple activated carbon samplers 310 can share a cover plate 320 and / or a heating sealing plate 340 .

[0098] In this embodiment, if Figure 5 As shown, the activated carbon activity verification structure 300 includes ten activated carbon samplers 310 .

[0099] The states of the pressure-triggered components 330 in the six activated carbon samplers 310 are monitored. If four or more of the ten pressure-triggered components 330 enter the triggered state, which is indicated by shaded circles in the figure, the proportion of the pressure-triggered components 330 entering the triggered state is 40%. The proportion is compared with the preset threshold value. If the preset threshold value is 50%, the desorption operation of the activated carbon bin 200 where the activated carbon activity verification structure 300 is located is not triggered.

[0100] By increasing the number of activated carbon activity verification structures 300 and judging whether to trigger the desorption operation by the proportion of the number of pressure-triggered components 330 in the trigger state, the activity status of the activated carbon particles in the activated carbon bin 200 can be verified more comprehensively and representatively, thereby reducing the possibility of triggering the desorption operation when most of the activated carbon particles are still active, avoiding unnecessary energy waste and achieving energy-saving and environmental protection effects.
