Description

Technical Field

[0001] The present invention relates to the technical field of flue gas, and more particularly to a flue gas purification device for environmental protection. Background Art

[0002] Flue gas is a mixture of gas and smoke, and is the main cause of air pollution in residential areas. The composition of flue gas is very complex, including water vapor, sulfur dioxide, etc., and smoke includes fuel ash, coal particles, oil droplets, and high-temperature cracking products, etc. Therefore, the pollution of flue gas to the environment is a complex pollution of multiple poisons.

[0003] The Chinese invention patent with the publication number CN107321100A discloses a flue gas purification device, wherein a middle partition plate is provided in the middle of the purification tower body, a raw flue gas inlet is provided in the lower part of the lower tower body, a purified gas outlet is provided at the top of the upper tower body, a smoke inlet pipe is vertically provided in the middle position of the lower tower body, the lower end of the smoke inlet pipe is connected to the raw flue gas inlet through a bend pipe joint, the upper end of the smoke inlet pipe is arranged near the middle partition plate, a plurality of circulating smoke pipes connecting the upper tower body and the lower tower body are arranged outside the purification tower body, an upper and a lower flue gas fairing are arranged in the purification tower body, and a plurality of spray nozzles are arranged correspondingly. After the flue gas enters the lower tower body of the purification tower, it is recoiled downward to the middle partition plate, and most of the dust particles are filtered out under the combined action of strong water mist flushing and the lower flue gas fairing, and then it is returned to the upper tower body by the circulating smoke pipe, and after multiple water mist flushing and the action of the upper flue gas fairing, the flue gas is thoroughly purified, and finally discharged after the water vapor is removed by the demister. The purification effect is good and the device is energy-saving and environmentally friendly.

[0004] It can be seen that the high-temperature flue gas generated in the current industrial production has a large content of particulate matter, and the filter screen is easily clogged after long-term use, which reduces the filtering effect during use.

DETAILED DESCRIPTION

[0029] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative. The flue gas purification device for environmental protection involved in the present invention is not limited to the various structures recorded in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0030] Reference Figure 1 and Figure 2The present invention provides a flue gas purification device for environmental protection, comprising a shell component 1, a smoke exhaust shell 2 is installed on the top of the shell component 1, a condensation component 3 is installed inside the shell component 1, a support frame 12 is fixedly connected to the top of the condensation component 3, a sprinkler 5 is installed at the bottom of the condensation component 3, a filter component 6 is installed at the bottom of the sprinkler 5 inside the shell component 1, a smoke inlet pipe 7 is installed at the bottom of the filter component 6, one end of the bottom of the smoke inlet pipe 7 extends out of the outside of the shell component 1 and is connected to an external pipeline, a guide cone 8 and a waste discharge component 9 are installed at the bottom of the smoke inlet pipe 7 inside the shell component 1, a cooling component 4 is installed on the side of the shell component 1, and the upper and lower ends of the cooling component 4 are respectively connected to the condensation component 3 and the waste discharge component 9, a transmission component 10 is installed on the front of the shell component 1, and a waste discharge pipe 11 is opened at the bottom of the back of the shell component 1;

[0031] In this embodiment, it should be specifically explained that the cooling component 4 includes a return pipe 401, a cooler 402 is installed on the return pipe 401, a water valve 403 is installed on the side of the cooler 402, and the cooler 402 cools the internal liquid of the return pipe 401. When a large amount of liquid is discharged, external liquid enters the interior of the return pipe 401 through the water valve 403 for replenishment.

[0032] The transmission assembly 10 includes a transmission motor 1001 and a transmission rod 1004. The bottom of the transmission motor 1001 is fixedly connected with a first gear 1002 and a second gear 1003. The upper and lower ends of the transmission rod 1004 are respectively fixedly connected with a spur gear and a bevel gear. The spur gear is meshingly connected with the second gear 1003, and the bevel gear is meshingly connected with the spiral pressure rod 902. During transmission, the transmission motor 1001 drives the first gear 1002 to rotate. Since the first gear 1002 is meshingly connected with the rotating ring 605, the rotation of the first gear 1002 drives the rotating ring 605 to rotate together, and the transmission rod 1004 drives the spiral pressure rod 902 to rotate.

[0033] The main difference between this embodiment and the prior art is that in this embodiment, the filter screen is turned over to achieve self-cleaning of the filter screen, and the filtration effect is stabilized. At the same time, the rotation of the motor is used to achieve the drying of the filter residue and the heat exchange of the gas, specifically, the condensation component 3, the filtering component 6, and the waste discharge component 9;

[0034] The above structure is the main structure of this embodiment, which solves the problem of reduced filtering effect caused by accumulation of filter residue in the filter screen in the current flue gas purification, and also solves the problem of high water content in the discharged filter residue. The sprinkler 5 is an existing structure, and the specific structure and mixing method of the liquid mixing inside the sprinkler 5 are not described in detail in this embodiment.

[0035] Reference Figure 4The condensation component 3 includes a condensation shell 301, and a heat exchange tube 302 is installed inside the condensation shell 301. The upper and lower ends of the heat exchange tube 302 are connected to the outside through the water inlet hole 304 and the water outlet hole 303 respectively. A liquid flow groove 305 is opened on the outside of the bottom of the condensation shell 301. The diameter of the filter hole on the top of the condensation shell 301 is smaller than the bottom and is filled with a desiccant. The sprinkler 5 includes a sprinkler box 501, and a plurality of branch pipes 502 are opened on the side of the sprinkler box 501. A plurality of nozzles 503 are installed at the bottom of the branch pipe 502. The flue gas after desulfurization enters the interior of the condensation component 3. Since the interior of the heat exchange tube 302 is a cooled cooling liquid, the moisture in the gas after cooling through the heat exchange tube 302 condenses on the pipe surface of the heat exchange tube 302, completing the preliminary drying effect.

[0036] In this embodiment, it should be specifically explained that the condensation component 3 not only realizes the preliminary gas drying work, but also effectively reduces the temperature of the gas, so that the exhausted gas can be effectively used in various environments and participate in the gas circulation of the working environment.

[0037] Reference Figure 5-6 The filter assembly 6 includes a filter plate 601, which is composed of a conical surface and surrounding horizontal surfaces. The bottom of the conical surface is provided with a smoke inlet 609 and a smoke outlet 610. The smoke inlet 609 is connected to the smoke inlet pipe 7. The smoke enters the interior of the filter assembly 6 from the smoke inlet pipe 7 and exits from the smoke outlet 610. Discharge, a plurality of large filter holes 602 are provided at the top of the horizontal plane, a filter rod 604 is installed inside the large filter hole 602, a rotating groove 603 is provided on the outer side of the filter plate 601, a rotating ring 605 is installed inside the rotating groove 603, the number of teeth at the bottom of the rotating ring 605 is half the number of teeth of a single filter gear 6043, so that the rotating ring 605 can only drive a single filter rod 604 to rotate each time it passes a single filter rod 604 and can only rotate half a circle, a cleaning bracket 606 is installed on the inner side of the rotating ring 605, a cleaning plate 607 is installed at the bottom of the cleaning bracket 606, a brush is installed at the bottom of the cleaning plate 607, and the cleaning bracket 606 is installed on the upper surface of the conical surface through a positioning block 608.

[0038] In this embodiment, it should be specifically explained that the number of teeth at the bottom of the rotating ring 605 is half the number of teeth of a single filter gear 6043, so that the rotating ring 605 can only drive a single filter rod 604 to rotate and can only rotate half a circle each time it passes a single filter rod 604 during rotation, and after the rotating ring 605 rotates one circle, all the filter rods 604 complete a flip. With the subsequent rotation of the rotating ring 605, the cleaning plate 607 cleans the upper surface of the large filter hole 602, and the bottom brush cleans the filter residue and desulfurization precipitate accumulated on the filter ball 6042.

[0039] Reference Figure 7The filter rod 604 includes a filter connecting rod 6041, to which a plurality of filter balls 6042 are fixedly connected, and filter screens are installed at the upper and lower ends of the filter balls 6042. A filter gear 6043 is fixedly connected to one end of the filter connecting rod 6041, and the filter gear 6043 is meshed with the tooth groove at the bottom of the rotating ring 605. When the bottom tooth groove of the rotating ring 605 passes through the filter gear 6043, the meshing of the tooth groove causes the filter gear 6043 to rotate half a circle to achieve flipping. During the flipping process, the filter residue accumulated at the bottom of the filter ball 6042 will flip to the top.

[0040] In this embodiment, it is necessary to explain in detail that: the filter component 6 divides the upper and lower parts into a filter space and a desulfurization space. The flue gas in the filter space is adsorbed by a large number of water droplets, and part of the particulate matter in the flue gas is directly adsorbed by the water droplets and falls to the guide cone 8. The gas in the desulfurization space is contacted with the gas under the action of the alkaline liquid in the sprinkler 5 spraying downward, thereby achieving a desulfurization effect.

[0041] Reference Figure 8 The waste discharge assembly 9 includes a waste discharge body 901, a spiral pressure rod 902 is installed inside the waste discharge body 901, and the spiral pressure rod 902 includes a spiral rod and a cam 903. A waste removal pipe 906 is opened inside the waste removal pipe 906, and a plurality of secondary pressure rods 904 are installed at the bottom of the cam 903 inside the waste removal pipe 906. A return spring 905 is installed on the outer side of the secondary pressure rod 904. The secondary pressure rod 904 includes an arc-shaped pressure piece and a moving rod. The return spring 905 is installed on the outer side of the moving rod. When the top of the moving rod is subjected to the pressure of the cam 903, the moving rod moves downward, and the arc-shaped pressure piece filters the filter residue. The water generated by the filtering enters the inside of the reflux water tank 9012, and the impurities enter the waste discharge pipe 11 under the continuous action of the plurality of arc-shaped pressure pieces.

[0042] In this embodiment, it should be specifically explained that: under the action of the spiral rod, filter residue continuously enters the interior of the waste removal pipe 906, and a baffle effect is formed between the multiple arc plates so that the liquid cannot be directly discharged to the outside. After the filter residue is filtered, the subsequent part uses gravity to push the front part, so that the front part is effectively discharged, and the subsequent part enters the filter pressing position under the action of gravity.

[0043] Reference Fig. 9The waste discharge body 901 includes a waste discharge body 9011, a reflux water tank 9012 is provided at the bottom of the waste discharge body 9011, a filtering circular groove 9013 is provided at the top of the waste discharge body 9011, and a plurality of guide pipes 9014 are provided on both sides of the filtering circular groove 9013, the other end of the guide pipe 9014 is communicated with the reflux water tank 9012, a spiral pressure rod 902 is installed inside the filtering circular groove 9013, a reflux port 9015 is provided on the side of the waste discharge body 9011, and the two ends of the reflux port 9015 are respectively connected to the reflux water tank 9012 and the reflux pipe 401, and a conical groove is provided on the top of the waste discharge body 901. When the filter residue falls from the guide cone 8, it enters the inside of the filtering circular groove 9013 along the conical groove, and moves to the waste removal pipe 906 under the action of the spiral rod. During the movement, the liquid enters the inside of the reflux water tank 9012 through the guide pipe 9014.

[0044] In this embodiment, it should be specifically explained that: the reflux pipe 401 absorbs the liquid inside the reflux water tank 9012 through the reflux port 9015, and the guide pipe 9014 serves as a passage for the liquid. It has multiple openings at the bottom of the filter circular groove 9013 with a diameter smaller than the diameter for solids to pass through.

[0045] Working principle of the present invention:

[0046] The main problems solved by this embodiment are: utilizing the flipping of the filter to achieve self-cleaning of the filter and stabilize the filtering effect, while utilizing the rotation of the motor to achieve drying of the filter residue and heat exchange with the gas, thereby solving the problem of reduced filtering effect caused by accumulation of filter residue in the current flue gas purification, and solving the problem of high water content in the discharged filter residue.

[0047] The specific steps are as follows:

[0048] First, the high-temperature flue gas is transmitted to the interior through the smoke inlet pipe 7. Since the top of the smoke inlet pipe 7 is connected to the smoke inlet 609, the smoke enters the interior of the filter component 6 from the smoke inlet 609 and is discharged from the smoke outlet 610 to the filter space at the bottom of the filter component 6. The smoke in the filter space is adsorbed by a large number of water droplets. Part of the particles in the smoke are directly adsorbed by the water droplets and fall to the guide cone 8, and the remaining smoke moves upward through the filter component 6 to complete the filtration. During the filtration, the smoke enters the filter ball 6042 inside the large filter hole 602 from the bottom, and is filtered through the filter net on the filter ball 6042. The filtered gas overflows from the top of the filter ball 6042, and the particles in the gas accumulate at the bottom of the filter ball 6042. After the gas overflows from the filter component 6, it moves upward. At this time, the alkaline liquid in the sprinkler 5 is sprayed downward through the nozzle 503, and the sprayed liquid contacts the gas to achieve the desulfurization effect. The precipitate generated by the saturated liquid accumulates on the filter plate 601 together with the liquid. The liquid passes through the filter ball 6042 and moves downward to form water droplets to perform the first step of adsorption on the flue gas and the first step of initial wetting and cleaning of the bottom surface of the filter ball 6042. At the same time, the flue gas after desulfurization enters the interior of the condensation component 3. Since the interior of the heat exchange tube 302 is the cooling liquid after cooling, the moisture in the gas after cooling through the heat exchange tube 302 condenses on the pipe surface of the heat exchange tube 302, completing the initial drying effect. Since the diameter of the filter hole at the top of the condensation shell 301 is smaller than that at the bottom and is filled with desiccant, the desiccant dries the gas for a second time and is discharged to the outside through the smoke exhaust shell 2.

[0049] The transmission motor 1001 is started, and the transmission motor 1001 drives the first gear 1002 to rotate. Since the first gear 1002 is meshed and connected with the rotating ring 605, the rotation of the first gear 1002 drives the rotating ring 605 to rotate together. Since the bottom of the rotating ring 605 is provided with a tooth groove and meshes with the filter gear 6043, when the rotating ring 605 rotates, the rotating ring 605 drives the filter rod 604 to rotate. Since the number of tooth grooves at the bottom of the rotating ring 605 is half the number of teeth of a single filter gear 6043, the rotating ring 605 rotates each time after a single filter gear 6043 passes. When the filter rod 604 rotates, it can only drive a single filter rod 604 to rotate and can only rotate half a circle. At this time, the filter residue accumulated at the bottom of the filter ball 6042 will flip to the top. After the rotating ring 605 rotates one circle, all the filter rods 604 are turned over. At the same time, with the rotation of the rotating ring 605, the cleaning plate 607 cleans the upper surface of the large filter hole 602, and the bottom brush cleans the filter residue and desulfurization precipitate accumulated on the filter ball 6042, so that the filter ball 6042 always maintains a good filtering effect, and the filter hole will not be blocked to affect the filtering effect.

[0050] When the transmission motor 1001 is started, the transmission long rod 1004 drives the spiral pressure rod 902 to rotate. The spiral plate on the surface of the spiral pressure rod 902 performs preliminary treatment on the liquid inside the filter groove 9013, and the solid impurities are transported to the inside of the waste removal pipe 906. During the transportation process, the liquid enters the guide pipe 9014 on both sides and the bottom and flows into the return water tank 9012. The impurities containing water in the waste removal pipe 906 are squeezed by the secondary pressure rod 904 to further reduce the moisture in the impurities. The moisture enters the return water tank 9012 from the bottom of the secondary pressure rod 904. The impurities with reduced moisture are discharged to the outside through the waste discharge pipe 11. The water in the return water tank 9012 is absorbed from the reflux port 9015 by the reflux pipe 401, and is transported to the heat exchange tube 302 through the cooling of the cooler 402 to preliminarily dry the gas.

[0051] The above are only preferred embodiments of the present invention and are 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 in the protection scope of the present invention.
