Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, and specifically relates to a waste gas treatment device for energy and power engineering. Background Art

[0002] Waste gas purification mainly refers to the work of treating industrial waste gas generated in industrial sites, such as dust particles, flue gas soot, odor gases, and toxic and harmful gases. Common waste gas purifications include factory soot waste gas purification, workshop dust waste gas purification, organic waste gas purification, waste gas odor purification, acid-base waste gas purification, chemical industry waste gas purification, etc. The waste gas discharged from industrial production often has harmful effects on the environment and human health. Before being discharged into the atmosphere, purification measures should be taken to make it meet the requirements of waste gas emission standards. This process is called waste gas purification.

[0003] Traditional waste gas treatment devices for energy and power engineering usually consist of an air inlet, a filtration unit, a treatment unit, and an air outlet, etc. The waste gas enters from the air inlet and first passes through the filtration unit to remove impurities such as particulate matter; then it enters the treatment unit, where organic pollutants are decomposed through heating and the action of a catalyst in the catalytic combustion chamber, or harmful components are absorbed by the washing liquid in the scrubber; finally, the purified gas is discharged from the air outlet to achieve waste gas treatment.

[0004] However, most waste gas treatment devices only use a single-layer filter screen for particulate filtration. Due to the single pore size of the filter screen, it is difficult to intercept particulate pollutants of different particle sizes at the same time. For example, a filter screen with a larger pore size can quickly filter large particulate matter, but has a poor filtering effect on fine dust; while a filter screen with a small pore size can filter fine particles, but is easily blocked by large particles, resulting in a sharp increase in the resistance of waste gas flow. Even if the device is equipped with adsorption materials, it often uses a simple filling method, and the contact area between the adsorption materials and the waste gas is limited, making it difficult to fully adsorb harmful substances such as volatile organic compounds and odor molecules in the waste gas. Moreover, most adsorption materials cannot be reused or are inconvenient to replace. When the adsorption is saturated, if not replaced in time, not only can it no longer purify the waste gas, but it will also cause secondary release of pollutants, resulting in secondary pollution. Most catalytic combustion devices lack effective heat dissipation measures. During long-term operation, the temperature of the reaction bed continuously rises, accelerating the aging and inactivation of the catalyst, shortening the service life of the catalyst, increasing the operating cost, and traditional scrubbers mostly use a single spray head to spray the washing liquid, with a small gas-liquid contact area and a short contact time, resulting in limited absorption effect on the remaining harmful gases and particulate matter in the waste gas. In addition, the liquid droplets of the washing liquid sprayed by the spray head have a large particle size and low mass transfer efficiency, making it difficult to effectively remove fine particles and soluble pollutants, resulting in incomplete waste gas purification. Summary of the Invention

Specific embodiments

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] Please refer to the attached Figure 1 - attached Figure 6, an embodiment of the present invention provides an exhaust gas treatment device for energy and power engineering, including a base 1. A box body 2 is fixedly installed on the upper side of the base 1. An air inlet 3 is fixedly communicated with the front side of the box body 2. A coarse filter screen 5 is arranged inside the box body 2. A fine filter screen 6 is arranged above the coarse filter screen 5. An activated carbon mesh 7 is arranged above the fine filter screen 6. Installation components 8 are arranged on the outer sides of the coarse filter screen 5, the fine filter screen 6, and the activated carbon mesh 7. The installation component 8 includes an installation block 81. The installation block 81 is fixedly connected to the outer sides of the coarse filter screen 5, the fine filter screen 6, and the activated carbon mesh 7. A spring 82 is fixedly connected inside the installation block 81. One side of the spring 82 away from the installation block 81 is fixedly connected to a clamping block 83. A pulling block 85 is fixedly connected to the upper side of the clamping block 83. An installation groove 86 and a clamping groove 84 are arranged inside the box body 2. The installation groove 86 and the clamping groove 84 are communicated. The installation block 81 is slidably connected inside the installation groove 86. The clamping block 83 is clamped with the clamping groove 84. A connecting pipe 13 is fixedly communicated with the right side of the box body 2. An exhaust pipe 20 is fixedly communicated with the right side of the combustion chamber 14. The connecting pipe 13, the combustion chamber 14, and the exhaust pipe 20 are all connected to the scrubbing tower 21 through flanges. An exhaust pipe 24 is fixedly connected to the right side of the scrubbing tower 21. A guardrail 25 is fixedly connected to the upper side of the base 1. The guardrail 25 is arranged on the outer sides of the box body 2, the combustion chamber 14, and the scrubbing tower 21. A pressure sensor 10 is fixedly installed on the inner wall of the box body 2. An alarm 11 is fixedly installed on the front side of the box body 2;

[0036] Specifically, inside the box body 2, the waste gas sequentially passes through the coarse filter screen 5, the fine filter screen 6, and the activated carbon mesh 7, undergoing progressive preliminary purification. The coarse filter screen 5, with its structural design of larger pore diameters, can quickly intercept particulate matters with larger particle sizes such as gravel and wood chips in the waste gas, effectively reducing the load on the subsequent filter units. The fine filter screen 6, relying on its fine mesh structure, precisely captures dust particles with smaller particle sizes, further improving the filtration accuracy to ensure the effective removal of fine solid impurities in the waste gas. The activated carbon mesh 7, with its rich pore structure and strong adsorption performance, can efficiently adsorb harmful substances such as volatile organic compounds and odor molecules in the waste gas. During the installation of the filter screen, the operator slides the installation block 81 smoothly along the installation groove 86. As the installation block 81 advances, the clamping block 83 is gradually compressed by the inner wall of the installation groove 86 and retracts into the installation block 81, compressing the spring 82. When the installation block 81 reaches the designated position, the spring 82 restores its elastic deformation, pushing the clamping block 83 to precisely snap into the card slot 84, realizing the stable installation of the filter screen. During the continuous waste gas filtration process, the pressure sensor 10 installed on the inner wall of the box body 2 is always in a real-time monitoring state, closely monitoring the pressure changes inside the box body 2. As the particulate matters intercepted by the filter screen continuously accumulate, the pores of the filter screen gradually become blocked, resulting in an increase in the resistance to waste gas flow and a corresponding increase in the pressure inside the box body 2. When the pressure value exceeds the pre-set safety threshold, the pressure sensor 10 immediately transmits a signal to the controller 9, and the controller 9 quickly responds, triggering the alarm 11 to emit an audible and visual alarm, using a prominent warning to remind the staff to clean or replace the blocked filter screen in a timely manner.

[0037] Please refer to the attached Figure 2 , a box door 4 is hinged on the upper side of the box body 2, and a fixing component 12 is arranged on the right side of the box door 4. The fixing component 12 includes a first fixing plate 121, and the first fixing plate 121 is fixedly connected to the right side of the box door 4. A second fixing plate 122 is fixedly connected to the right side of the box body 2. An installation bolt 123 is arranged inside the first fixing plate 121 and the second fixing plate 122. A nut 124 is threadedly connected to the lower side of the installation bolt 123. A heating block 19 is fixedly installed on the inner wall of the combustion box 14;

[0038] Specifically, when it is necessary to perform maintenance or replace the filter screen inside the box body 2, the operator rotates the installation bolt 123 to make it pass through the first fixing plate 121 and the second fixing plate 122, and then uses the nut 124 for fastening, thereby realizing the stable fixation and convenient opening of the box door 4. After the box door 4 is opened, the staff pulls the pull block 85, and the pull block 85 drives the clamping block 83 to overcome the elastic force of the spring 82 and disengage from the card slot 84. At this time, the spring 82 is compressed and deformed, and the staff can easily take out the filter screen. Subsequently, the clamping block 83 is re-snapped into a suitable card slot 84, and by adjusting the spacing between the filter screens, the filtration space layout is further optimized, increasing the contact area between the waste gas and the filter screens, thereby improving the overall filtration efficiency.

[0039] Please refer to the appendix Figure 9 - Appendix Figure 10 On the right side of the box body 2, a combustion chamber 14 is provided. Inside the combustion chamber 14, a placement frame 15 is provided. Inside the placement frame 15, three stainless steel meshes 16 are fixedly installed. The placement frame 15 is slidably connected to the right side of the cooling fan 184. A sealing plate 17 is fixedly connected to the front side of the placement frame 15. A heating block 19 is fixedly installed on the inner wall of the combustion chamber 14. A sliding assembly 18 is provided outside the combustion chamber 14. The sliding assembly 18 includes an electric push rod 181. The electric push rod 181 is fixedly installed on the outside of the combustion chamber 14. The telescopic end of the electric push rod 181 is fixedly connected to a connecting block 182. The connecting block 182 is fixedly connected to the sealing plate 17. A fixed seat 183 is fixedly connected to the upper side of the base 1. Three cooling fans 184 are installed inside the fixed seat 183. A slider 185 is fixedly connected to the outside of the placement frame 15. A chute 186 is provided inside the combustion chamber 14. The slider 185 is slidably connected to the inside of the chute 186;

[0040] Specifically, the preliminarily filtered waste gas smoothly enters the combustion chamber 14 through the connecting pipe 13, where more critical catalytic combustion treatment will be carried out. The placement frame 15 provided inside the combustion chamber 14, with the three stainless steel meshes 16 fixedly installed inside it, provides a stable bearing platform for the catalyst. When the catalyst reaches the end of its service life or its activity decreases and needs to be replaced, the operator starts the electric push rod 181. The telescopic end of the electric push rod 181 starts to move, driving the sealing plate 17 and the placement frame 15 to slide smoothly along the chute 186 through the connecting block 182, enabling the placement frame 15 to be conveniently withdrawn from the combustion chamber 14, facilitating the staff to quickly replace the catalyst. At the same time, the three cooling fans 184 installed inside the fixed seat 183 on the base 1 keep running. Through the way of forced convection, the excess heat generated during the operation of the combustion chamber 14 is timely taken away, effectively preventing the combustion chamber 14 from affecting the activity of the catalyst due to excessive temperature and ensuring the safe and stable operation of the equipment. Inside the combustion chamber 14, the heating block 19 plays a key role in heating the waste gas to the optimal ignition temperature of the catalyst. Under this temperature condition, the catalyst can fully exert its catalytic activity, prompting the organic pollutants in the waste gas to undergo a catalytic combustion reaction, efficiently converting these harmful substances into harmless substances such as carbon dioxide and water, and significantly reducing the pollution degree of the waste gas.

[0041] Please refer to the appendix Figure 11, a scrubbing tower 21 is provided on the right side of the combustion chamber 14. A scrubbing assembly 23 is provided inside the scrubbing tower 21. The scrubbing assembly 23 includes a ring water pipe 231 which is fixedly installed at the inner top of the scrubbing tower 21. A water inlet pipe 232 is fixedly connected to the right side of the ring water pipe 231. Atomizing nozzles 233 are fixedly installed on the lower side of the ring water pipe 231. A packing layer 234 is fixedly installed inside the scrubbing tower 21. A drain pipe 235 is fixedly connected to the front side of the scrubbing tower 21. A solenoid valve 236 is fixedly installed on the outer side of the drain pipe 235. A controller 9 is fixedly installed on the front side of the box body 2. The controller 9 is electrically connected to the pressure sensor 10, the alarm 11, the electric push rod 181, the cooling fan 184, the heating block 19 and the solenoid valve 236;

[0042] Specifically, the exhaust gas after catalytic combustion treatment enters the scrubbing tower 21 through the outlet pipe 20 and undergoes the final in-depth purification treatment. Inside the scrubbing tower 21, the exhaust gas is refined. The water inlet pipe 232 continuously transports the scrubbing liquid to the ring water pipe 231. The ring water pipe 231 is fixedly installed at the inner top of the scrubbing tower 21. The atomizing nozzles 233 evenly distributed on its lower side can efficiently atomize the scrubbing liquid into fine misty water droplets. These misty water droplets come into full contact with the exhaust gas, greatly increasing the contact area between the gas and liquid phases. The packing layer 234 fixedly installed inside the scrubbing tower 21 with its unique structural design further extends the contact time between the exhaust gas and the scrubbing liquid, strengthening the mass transfer process. During the scrubbing process, relying on the dual effects of physical absorption and chemical reaction, the scrubbing liquid can effectively absorb the residual harmful gases and the particulate matter that have not been completely removed in the exhaust gas, achieving in-depth purification of the exhaust gas. As the scrubbing process continues, impurities will continuously accumulate in the scrubbing liquid in the scrubbing tower 21, and its purification ability gradually decreases. When the set discharge conditions are reached, the controller 9 issues an instruction to control the solenoid valve 236 to open, and the scrubbing wastewater is smoothly discharged through the drain pipe 235. After multiple treatment processes such as rough filtration, adsorption, catalytic combustion, and scrubbing, the exhaust gas originally containing a large amount of pollutants is finally converted into purified exhaust gas meeting the emission standards and is safely discharged into the atmosphere through the exhaust pipe 24, completing the entire exhaust gas treatment process and achieving effective protection of the environment.

[0043] Working principle: When using this device, the waste gas first enters the box body 2 from the air inlet 3. Inside the box body 2, the waste gas passes through the coarse filter screen 5, the fine filter screen 6 and the activated carbon mesh 7 in sequence for preliminary purification. The coarse filter screen 5 can intercept larger particulate matters in the waste gas and play a role in preliminary filtration; the fine filter screen 6 further filters smaller particulate matters to improve the filtration accuracy; the activated carbon mesh 7, relying on its strong adsorption ability, adsorbs harmful substances in the waste gas, such as volatile organic compounds, etc. When installing the filter screen, slide the installation block 81 along the installation groove 86. During the waste gas filtration process, the pressure sensor 10 on the inner wall of the box body 2 monitors the pressure change inside the box body 2 in real time. As the use time of the filter screen increases, a large amount of particulate matters will accumulate on the filter screen, resulting in the blockage of the filter screen, and then the pressure inside the box body 2 increases. When the pressure exceeds the set threshold, the pressure sensor 10 transmits the signal to the controller 9, and the controller 9 triggers the alarm 11 to give an alarm;

[0044] When it is necessary to repair or replace the filter screen inside the box body 2, rotate the installation bolt 123. The installation bolt 123 passes through the first fixing plate 121 and the second fixing plate 122 and is tightened by the nut 124 to fix the box door 4. When the box door 4 is opened, pull the pull block 85. The pull block 85 pushes the clamping block 83 out of the clamping groove 84, and at the same time the spring 82 is compressed, take out the filter screen, and then snap the clamping block 83 into the specified clamping groove 84 to adjust the spacing between the filter screens and increase the filtration area;

[0045] The waste gas that has been preliminarily filtered enters the combustion chamber 14 through the connecting pipe 13. There is a placement frame 15 inside the combustion chamber 14. Three stainless steel meshes 16 are fixedly installed in the placement frame 15 to carry the catalyst. When it is necessary to replace the catalyst, start the electric push rod 181. When the telescopic end of the electric push rod 181 extends or retracts, it drives the sealing plate 17 and the placement frame 15 to slide in the sliding groove 186 through the connecting block 182, which is convenient to pull out the placement frame 15 from the combustion chamber 14 for replacing the catalyst. At the same time, three heat dissipation fans 184 are installed inside the fixed seat 183 on the base 1. The heat dissipation fans 184 can dissipate heat from the combustion chamber 14 to prevent the temperature of the combustion chamber 14 from being too high and ensure the activity of the catalyst and the safe operation of the equipment. Inside the combustion chamber 14, the heating block 19 heats the waste gas to make the waste gas reach the ignition temperature of the catalyst. Under the action of the catalyst, the organic pollutants in the waste gas undergo a catalytic combustion reaction and are converted into harmless substances such as carbon dioxide and water;

[0046] The exhaust gas after catalytic combustion treatment enters the scrubbing tower 21 through the outlet pipe 20. Inside the scrubbing tower 21, the scrubbing assembly 23 further purifies the exhaust gas. The water inlet pipe 232 conveys the scrubbing liquid to the annular water pipe 231, which is fixedly installed at the inner top of the scrubbing tower 21. The scrubbing liquid is sprayed out in a mist form through the atomizing nozzles 233 and comes into full contact with the exhaust gas. A packing layer 234 is also fixedly installed inside the scrubbing tower 21. The packing layer 234 increases the contact area and contact time between the exhaust gas and the scrubbing liquid, improving the scrubbing effect. During the scrubbing process, the scrubbing liquid can absorb the harmful gases and residual particulate matter in the exhaust gas, further purifying the exhaust gas;

[0047] As the scrubbing process progresses, impurities will gradually accumulate in the scrubbing liquid inside the scrubbing tower 21. When it is necessary to discharge the scrubbing wastewater, the controller 9 controls the solenoid valve 236 to open, and the scrubbing wastewater is discharged through the drain pipe 235. The purified exhaust gas after multi-stage treatment is discharged from the exhaust pipe 24 of the device.

[0048] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
