Description

Technical Field

[0001] The present application relates to the technical field of flue gas purification, and in particular to an integrated flue gas purification device. Background Art

[0002] With the acceleration of industrialization and the deepening of urbanization, flue gas pollution is becoming increasingly serious, affecting not only human health but also the environment. Flue gas typically contains large amounts of particulate matter, harmful gases, and odors, such as PM2.5, sulfur dioxide, and nitrogen oxides. These substances harm the human respiratory and cardiovascular systems and exacerbate air pollution. Therefore, efficient and reliable flue gas purification technologies have become a research hotspot in the fields of environmental protection and public health.

[0003] Traditional flue gas purification devices mostly use single filtration or adsorption technologies, such as electrostatic precipitators and wet flue gas desulfurization. While these technologies can purify flue gas to a certain extent, they are limited in removing fine particulate matter and eliminating odors. Furthermore, the equipment is bulky, complex to operate, and has high maintenance costs. Furthermore, traditional purification devices often require regular replacement of filter elements or chemical reagents, which not only increases operating costs but also may cause secondary pollution.

DETAILED DESCRIPTION

[0023] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application are clearly and completely described below. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts also fall within the scope of protection of this application.

[0024] refer to Figures 1 to 4The present application provides an integrated flue gas purification device, comprising: a flue gas collection hood 100, a flue gas inlet pipe 200, a flue gas purification housing 300, and an induced draft fan 400, which are sequentially connected. The induced draft fan 400 sequentially draws flue gas through the flue gas collection hood 100 and the flue gas inlet pipe 200 into the flue gas purification housing 300. The flue gas collection hood 100 can effectively collect flue gas from different directions, ensuring that the flue gas is fully captured and introduced into the flue gas purification housing 300.

[0025] An installation frame 500 is slidingly arranged in the flue gas purification shell 300, and a sliding through hole 301 is opened on its side wall perpendicular to the flue gas flow direction. The sliding direction of the installation frame 500 in the flue gas purification shell 300 is perpendicular to the flow direction of the flue gas; a primary filter screen 501, a particulate matter capture net 502, an odor elimination net 503 and a fine filter screen 504 are arranged in sequence along the flow direction of the flue gas in the installation frame 500, and a push-pull plate 505 matching the sliding through hole 301 is provided on the installation frame 500, and a filter replacement through hole 506 is provided on the top. The inner bottom of the flue gas purification housing 300 may be provided with a slot that mates with the bottom of the mounting frame 500, allowing the mounting frame 500 to slide within the slot. The apertures of the primary filter 501, the particle trap 502, and the fine filter 504 decrease in size. The primary filter 501 intercepts large particles in the flue gas, such as dust and coal slag, thereby reducing the burden on subsequent purification components and extending the service life of the entire purification system. After being filtered by the primary filter 501, the flue gas then passes through the particle trap 502. The particle trap 502 has a higher filtration accuracy and can capture even finer particles in the flue gas, such as harmful particles like PM2.5, further purifying the flue gas. The flue gas then enters the odor elimination filter 503. The odor elimination filter 503 typically contains activated carbon or other adsorbent materials that effectively absorb and eliminate odorous components in the flue gas, such as volatile organic compounds (VOCs). The flue gas passes through the fine filter 504, marking the final stage of the purification process. The fine filter 504 has extremely high filtration efficiency and can intercept tiny particles and bacteria remaining in the flue gas, ensuring that the discharged air meets environmental protection standards.

[0026] The integrated flue gas purification device provided in the present application uses an induced draft fan 400 to draw the flue gas into the flue gas purification shell 300 through the flue gas collection hood 100 and the flue gas inlet pipe 200 in sequence, and uses the primary filter 501, the particle collection net 502, the odor elimination net 503 and the fine filter 504 in the flue gas purification shell 300 to purify the large impurities, particulate matter, odor and fine particles with smaller particles carried in the flue gas step by step, thereby improving the efficiency of flue gas purification and the purity of the purified flue gas, and then the purified flue gas is discharged to avoid it from polluting the environment. In addition, the primary filter 501, the particulate matter collection net 502, the odor elimination net 503 and the fine filter 504 are all arranged in the installation frame 500, and the installation frame 500 is slidably connected to the flue gas purification shell 300. The installation frame 500 can be pulled out of the flue gas purification shell 300 by pulling the push-pull plate 505, which facilitates the replacement of the primary filter 501, the particulate matter collection net 502, the odor elimination net 503 and the fine filter 504 on the installation frame 500, thereby improving the convenience of installation and disassembly of the above-mentioned filters.

[0027] In some embodiments, reference Figure 2 In the present application, sealing rings 507 are respectively provided at both ends of the installation frame 500 close to the direction of smoke flow. The two sealing rings 507 are used to enclose the installation frame 500 and the inner peripheral wall of the smoke purification shell 300 to form a sealed chamber 600, so that the smoke in the sealed chamber 600 passes through the primary filter 501, the particulate matter capture net 502, the odor elimination net 503 and the fine filter 504 on the installation frame 500 for processing, thereby improving the purification efficiency of the smoke.

[0028] In some embodiments, reference Figure 2 and Figure 3 The distance between the two ends of the push-pull plate 505 in the present application along the direction of smoke flow is greater than the distance between the two inner side walls of the sliding through hole 301 along the direction of smoke flow. The smoke purification shell 300 is provided with two mounting grooves 302 respectively located on both sides of the sliding through hole 301 along the direction of smoke flow. The distance between the two opposite inner side walls of the two mounting grooves 302 matches the length of the push-pull plate 505, which facilitates pulling the push-pull plate 505 out of the sliding through hole 301 and the tightness of the installation of the push-pull plate 505 at the sliding through hole 301.

[0029] In addition, vertical sealing strips 700 are respectively provided on the inner side walls of the two mounting grooves 302 opposite to the push-pull plate 505 , so as to ensure the sealing inside the flue gas purification shell and prevent flue gas from overflowing from the connection between the push-pull plate 505 and the sliding through hole 301 .

[0030] In some embodiments, reference Figure 2In the present application, connecting plates 508 are respectively provided on the side walls of the installation frame 500 at both ends along the direction of flue gas flow and opposite to the push-pull plate 505. The two connecting plates 508 are both provided near the bottom of the installation frame 500. Each connecting plate 508 is away from a side wall of the flue gas purification housing 300 and is provided with an elastic member 800 near its bottom end. The end of the elastic member 800 away from the connecting plate 508 is provided on the inner wall of the flue gas purification housing 300 on the side where the sliding through hole 301 is provided. The elastic member 800 can be a compression spring. When the installation frame 500 is pulled out of the flue gas purification housing 300, the connecting plate 508 squeezes the elastic member 800, and the elastic member 800 applies an elastic force in the opposite direction to the connecting plate 508, thereby preventing the installation frame 500 from completely sliding out of the flue gas purification housing 300, thereby improving the stability of the installation frame 500 in the flue gas purification housing 300.

[0031] In some embodiments, reference Figure 2 In this application, the mounting frame 500 is connected to airflow guide cylinders 509 at both ends along the direction of smoke flow. These guide cylinders guide the smoke for even distribution, thereby improving smoke purification efficiency. The distance between the two ends of the airflow guide cylinders 509, each facing away from the mounting frame 500, is smaller than the distance between the two inner sidewalls of the sliding hole 301 along the direction of smoke flow. This facilitates pulling the mounting frame 500 out of the sliding hole 301 to replace the primary filter 501, particulate matter capture net 502, odor elimination net 503, and fine filter 504 located thereon.

[0032] In some embodiments, reference Figure 1 and Figure 2 In the present application, a handle 5051 is provided on the outer wall of the push-pull plate 505. The handle 5051 facilitates pulling the push-pull plate 505 to pull the installation frame 500 out of or push it into the flue gas purification housing 300, thereby improving the convenience of replacing and maintaining the filters in the installation frame 500.

[0033] In some embodiments, reference Figure 2 In the present application, a support block 303 is provided on the inner side wall of the flue gas purification housing 300 relative to the sliding through hole 301. The support block 303 is fixedly connected to the inner wall of the flue gas purification housing 300. The support block 303 is away from the inner side wall of the flue gas purification housing 300 and abuts against the mounting frame 500 to ensure the stability of the mounting frame 500 in the flue gas purification housing 300.

[0034] In some embodiments, reference Figure 1One end of the air outlet of the induced draft fan 400 in the present application is connected to a dustproof box 901 through an air inlet duct 900. The dustproof box 901 prevents the purified air from being re-introduced into external dust, further ensuring the purity of the flue gas discharged from the dustproof box 901.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
