Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of flue gas treatment, in particular to a flue gas treatment device of an industrial boiler. BACKGROUND

[0002] Industrial boilers are important heat power equipment, and the flue gas generated by combustion contains particulate matter (dust), sulfur oxides (SOx), nitrogen oxides (NOx) and other pollutants. In order to meet the increasingly stringent environmental emission standards, a flue gas treatment device needs to be used to filter and treat the flue gas generated by the industrial boiler.

[0003] The existing flue gas treatment is divided into bag filter treatment and spray treatment. In the spray treatment process, the liquid is generally sprayed and mixed with the flue gas to remove the impurities in the flue gas. Due to the influence of the spray method and the flue gas distribution, the liquid and the flue gas are not uniformly mixed. In the mixed area, part of the flue gas (especially the flue gas in the center of the flow field) not only fails to effectively contact the liquid droplets, but also forms "air flow short circuit". The dust and SO2 pollutants in these flue gases almost directly penetrate the absorption tower without treatment, resulting in an increase in outlet concentration and difficulty in meeting the ultra-low emission requirements. In order to ensure that the whole meets the standard, the system cannot be over-sprayed with a reaction agent (such as an alkaline absorbent). In the well-mixed area, the excess reaction agent is wasted, and in the poorly mixed area, the reaction agent is insufficient, resulting in a large increase in the consumption of the agent and an increase in the operating cost.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0037] In this embodiment, as shown in Figure 4 The water curtain processing mechanism includes annular plate 610 and protection ring 604, annular plate 610 is located below spray head 7, annular groove 611 is formed in the outer surface of annular plate 610, slide plate 612 is symmetrically and slidably connected inside annular groove 611, slide plate 612 is fixedly connected to the inner side wall of processing box 2, drainage groove 614 is formed in the upper end surface of annular plate 610, water storage barrel 607 is fixedly connected to the center of the upper end surface of annular plate 610, water storage barrel 607 is located directly below spray head 7, water outlet 613 is formed in the outer surface of water storage barrel 607, the number of water outlet 613 is the same as that of drainage groove 614, and water outlet 613 corresponds to drainage groove 614, the liquid inside water storage barrel 607 flows uniformly into drainage groove 614 formed in the upper end surface of annular plate 610 through water outlet 613.

[0038] In this embodiment, as shown in Figure 3 The outer surface of water storage barrel 607 is fixedly connected with annular rack 608, one side of annular rack 608 is meshingly connected with transmission gear 609, drive shaft 603 is fixedly connected to the upper end of transmission gear 609, drive shaft 603 is rotatably connected to processing box 2, one end of drive shaft 603 penetrating processing box 2 is fixedly connected with drive motor 601, drive motor 601 is fixedly connected with support frame 602, support frame 602 is fixedly connected to the upper end of processing box 2, when drive motor 601 is turned on to drive drive shaft 603 to rotate, transmission gear 609 connected to the lower end of drive shaft 603 rotates, and transmission gear 609 drives water storage barrel 607 to rotate by meshing with annular rack 608, thereby forming centrifugal force.

[0039] In this embodiment, as shown in Figure 2 And Figure 3As shown, the ring gear 608 and the transmission gear 609 are located inside the protective ring 604, the protective ring 604 is sleeved on the outer surface of the water storage barrel 607, the upper end surface of the protective ring 604 is symmetrically and fixedly connected with the support plate 605, and the support plate 605 is fixedly connected to the inner top of the treatment box 2. The protective ring 604 can protect the ring gear 608 and the transmission gear 609, avoid the influence of water vapor and flue gas in the treatment box 2 on the ring gear 608 and the transmission gear 609, and prolong the service life of the ring gear 608 and the transmission gear 609.

[0040] In this embodiment, as shown in the figure, Figure 3 As shown, the lower end surface of the annular plate 610 is fixedly connected with the fan blades 606 at equal intervals, and when the annular plate 610 rotates, the fan blades 606 can be driven to rotate synchronously, so that the fan blades 606 form an air current to blow the flue gas to flow upward along the inner wall of the treatment box 2.

[0041] In the prior art, due to the influence of the spraying mode and the distribution of flue gas, the mixture of liquid and flue gas is not uniform, and in the area where the mixture is not uniform, part of the flue gas (especially the flue gas in the center of the flow field) not only fails to contact the liquid droplets effectively, but also forms "air flow short circuit", and the dust and SO2 pollutants in these flue gases almost directly penetrate the absorption tower without treatment, resulting in an increase in outlet concentration and difficulty in meeting the ultra-low emission requirement. Moreover, in order to ensure that the whole meets the standard, the system cannot spray too much reaction agent (such as alkaline absorbent), and in the area where the mixture is good, the excess reaction agent is wasted, and in the area where the mixture is poor, the reaction agent is insufficient, resulting in a large increase in the consumption of reagents and an increase in operating costs. Compared with the prior art, the centrifugal force can form an annular water curtain in the treatment box 2, so that the flue gas passes through the water curtain during the rising process, and the flue gas is filtered. Not only can the randomness and unevenness of the flue gas flow be completely broken, but also all the flue gas must follow the preset optimal path to contact the liquid droplets fully and efficiently, which fundamentally eliminates the phenomenon that part of the flue gas escapes without treatment, so that every flue gas can meet the requirement of deep purification, thereby ensuring that the emission concentration meets and is better than the most stringent ultra-low emission standard. Moreover, the annular water curtain realizes "full and uniform" treatment of the flue gas, completely eliminates the reagent distribution dilemma of "local excess and local deficiency" in the traditional technology, and there is no need to spray too much to make up for the uneven mixture, thereby greatly reducing the main operating cost from the source, realizing precise and economical pollutant removal.

[0042] Wherein, through the setting of the water storage bucket 607 and the water outlet 613, liquid can be uniformly delivered into each drainage groove 614 opened on the upper end face of the annular plate 610 during the formation of the annular water curtain, not only improving the stability and consistency of the water quality of the entire flue gas treatment system, providing the most core hardware guarantee for realizing stable and standard ultra-low emission, but also making the operation and regulation of the entire system more simple and accurate, laying a solid foundation for forming a perfect annular water curtain with uniform thickness, stable flow and no weak links, thereby building an extremely reliable and uniform purification defense line.

[0043] In other aspects, the embodiment also provides a flue gas filtering and anti-blocking mechanism for facilitating the circulation of flue gas, as shown in Figure 2 、 Figure 5 Figure 7 The flue gas filtering and anti-blocking mechanism comprises a filter plate 801 fixedly connected to the inside of the treatment box 2, the filter plate 801 being located above the annular plate 610 and sleeved on the outer surface of the water storage bucket 607.

[0044] In the embodiment, as shown in Figure 6 , the upper end face of the filter plate 801 is symmetrically provided with a beating plate 804, the upper end face of the beating plate 804 is fixedly connected with an elastic telescopic column 806 at the center, the outer surface of the elastic telescopic column 806 is slidingly connected with a connecting plate 805, and the connecting plate 805 is fixedly connected to the outer surface of the water storage bucket 607, so that when the elastic telescopic column 806 slides up and down on the outer surface of the connecting plate 805, the beating plate 804 will knock the upper end face of the filter plate 801.

[0045] In the embodiment, as shown in Figure 5 and Figure 6 , the upper end of the elastic telescopic column 806 is fixedly connected with a linkage column 807, a fixed ring 802 is arranged between the two linkage columns 807, the fixed ring 802 is fixedly connected to the lower end of the protective ring 604, a corrugated groove 803 is opened on the outer surface of the fixed ring 802, and the linkage column 807 is slidingly connected in the corrugated groove 803, so that when the elastic telescopic column 806 drives the linkage column 807 to rotate, under the influence of the corrugated groove 803, the linkage column 807 will reciprocate up and down on the connecting plate 805 synchronously during the annular movement of the elastic telescopic column 806.

[0046] In the embodiment, as shown in Figure 6 and Figure 7 ​As shown, the elastic telescopic column 806 includes a hollow column 8061 and an extension column 8062, the extension column 8062 is slidingly connected to the hollow column 8061, the hollow column 8061 is slidingly connected to the connecting plate 805, the extension column 8062 is fixedly connected to the upper end surface of the beating plate 804, a spring 8063 is fixedly connected between the extension column 8062 and the inside of the hollow column 8061, when the hollow column 8061 pushes the extension column 8062 to descend, and the extension column 8062 cannot descend, it will slide into the hollow column 8061, and the spring 8063 is extruded.

[0047] Compared with the prior art, the water curtain formed by rotation by centrifugal force can filter flue gas, and at the same time, the formed water curtain can flush the filter plate 801. Through the continuous flushing of the water curtain, the dust, sticky pollutants and reaction crystals accumulated on the filter plate 801 can be peeled off and removed in real time and continuously. This fundamentally eliminates the problems of filter channel blockage, airflow resistance increase and purification efficiency decrease caused by dirt accumulation. Moreover, the rotating water curtain synchronously undertakes the dual missions of filtering and self-cleaning, forms a perfect internal environmental protection closed loop, and completely eliminates the factor of forced shutdown for processing due to filter plate 801 blockage.

[0048] The working process and principle involved in the above embodiment are as follows:

[0049] It should be noted that the water pipe 5 is connected to the water tank at the end away from the spray head 7, and liquid is pumped from the inside of the water tank through the water pipe 5 and sprayed out from the spray head 7;

[0050] When the worker needs to treat the boiler flue gas, first through the air inlet 3, the flue gas is discharged to the inside of the treatment box 2, first the liquid in the water tank is extracted by the water pump, is transported to the spray head 7 through the water pipe 5, is sprayed from the spray head 7, and the liquid sprayed from the spray head 7 is collected by the water storage bucket 607 below, at this time the driving motor 601 is opened, the driving shaft 603 is rotated, the transmission gear 609 connected to the lower end of the driving shaft 603 is rotated, the side of the transmission gear 609 is engaged and connected with the annular rack 608, the annular rack 608 is fixedly connected to the outer surface of the water storage bucket 607, the water storage bucket 607 is fixedly connected to the upper end surface of the annular plate 610, and the annular plate 610 is rotatably connected to the inside of the treatment box 2 through the annular groove 611 formed in the outer surface and the sliding plate 612 slidably connected in the annular groove 611, therefore, with the rotation of the transmission gear 609, the annular rack 608 is driven to rotate the water storage bucket 607 by the engagement of the transmission gear 609 and the annular rack 608, so that the annular plate 610 connected to the lower end of the water storage bucket 607 rotates synchronously, in the process of rotating the water storage bucket 607, the liquid in the water storage bucket 607 will flow into the drainage groove 614 formed in the upper end surface of the annular plate 610 through the centrifugal force and the water outlet 613 formed in the outer surface of the water storage bucket 607, and with the rotation of the annular plate 610, the liquid in the drainage groove 614 is rotated to form a circular distribution, so that the liquid forms a circular water curtain in the treatment box 2, at this time the flue gas rises in the treatment box 2 and passes through the water curtain for filtering, not only can completely break the randomness and unevenness of the flue gas flow, force all flue gas to follow the preset best path and liquid drops to fully and efficiently contact, which fundamentally eliminates the phenomenon that part of the flue gas escapes without treatment, so that every flue gas can meet the requirement of deep purification, thereby ensuring that the emission concentration is stable and reaches and exceeds the most stringent ultra-low emission standard, and the annular water curtain realizes "full and uniform" treatment of the flue gas, completely eliminates the drug distribution dilemma of "local excess and local deficiency" in the traditional technology, and there is no need to spray excessively to make up for uneven mixing, which greatly reduces the main operating cost from the source, realizes accurate and economical pollutant removal;

[0051] Wherein, by setting the water storage bucket 607 and the water outlet 613, the liquid can be uniformly delivered to each drainage groove 614 formed in the upper end surface of the annular plate 610 during the formation of the annular water curtain, not only improving the stability and consistency of the water quality of the entire flue gas treatment system, providing the most core hardware guarantee for realizing stable and standard ultra-low emission, but also making the operation and regulation of the entire system more simple and accurate, laying a solid foundation for forming a perfect annular water curtain with uniform thickness, stable flow and no weak link, thereby building a reliable and uniform purification defense line;

[0052] After the formation of the annular water curtain, the water curtain will contact the inner side wall of the treatment box 2, flow downward along the inner side wall of the treatment box 2, and clean the impurities attached to the inner side wall of the treatment box 2. During the process of rotating the annular plate 610 to form a liquid annular water curtain through the guide groove 614, the annular plate 610 is fixedly connected with the fan blades 606 at the lower end surface of the annular plate 610, so that the annular plate 610 drives the fan blades 606 to rotate synchronously, forming an airflow in the treatment box 2, blowing the flue gas entering the treatment box 2 to the inner side wall of the treatment box 2 to rise, and the rotating fan blades 606 generate an axisymmetric airflow field, thereby continuously blowing the flue gas from the central area to the inner wall water curtain area, completely eliminating the vortex dead angle and short-circuit flow formed by the traditional spraying, and ensuring that every flue gas cannot escape from the most sufficient collision, cutting and fusion with the water curtain, further improving the treatment effect of the flue gas;

[0053] After the flue gas passes through the water curtain, it will contact the filter plate 801 arranged above the annular plate 610, and pass through the filter plate 801 for filtering, so that the filter plate 801 performs secondary filtering on the flue gas. Since the filter plate 801 is arranged above the annular plate 610, during the process of rotating the annular plate 610 to form a water curtain, the water curtain will synchronously flush the lower end surface of the filter plate 801. Through the continuous flushing of the water curtain, the dust, sticky pollutants and reaction crystals accumulated on the filter plate 801 can be peeled off and removed in real time and continuously, which fundamentally eliminates the problems of filter channel blockage, airflow resistance increase and purification efficiency decrease caused by dirt accumulation. Moreover, the rotating water curtain synchronously assumes the dual missions of filtering and self-cleaning, forming a perfect internal environmental protection closed loop, and completely eliminating the factor of forced shutdown for treatment due to the blockage of the filter plate 801;

[0054] During the rotation of the water storage bucket 607, the water storage bucket 607 drives the symmetrical connection plate 805 on the outer surface to rotate synchronously. Since the hollow column 8061 is slidably connected on the connection plate 805, and the extension column 8062 is slidably connected at the lower end of the hollow column 8061 and is fixedly connected to the upper end surface of the beating plate 804, the beating plate 804 can be driven to rotate synchronously by the hollow column 8061 and the extension column 8062 during the rotation of the connection plate 805 following the water storage bucket 607. At this time, since the hollow column 8061 is connected to the linkage column 807 at the upper end, and the linkage column 807 is slidably connected in the corrugated groove 803 on the outer surface of the fixed ring 802, the linkage column 807 can be driven to rotate synchronously with the hollow column 8061 during the rotation of the connection plate 805, so that the linkage column 807 slides in the corrugated groove 803, and the hollow column 8061 reciprocates on the connection plate 805. During the upward movement of the hollow column 8061, the hollow column 8061 drives the beating plate 804 to move upward away from the filter plate 801 through the extension column 8062. Conversely, when the hollow column 8061 moves downward, the beating plate 804 is driven to move downward and hit the upper end surface of the filter plate 801 through the extension column 8062. When the beating plate 804 and the filter plate 801 are in contact, the beating plate 804 will push the extension column 8062 to slide into the hollow column 8061 as the hollow column 8061 continues to move downward, so as to extrude the spring 8063 connected between the extension column 8062 and the hollow column 8061. Thus, the beating plate 804 can be driven to hit the upper side of the filter plate 801 during the rotation of the water curtain, so as to knock off the blockages attached to the lower end surface of the filter plate 801. The water flow is responsible for dissolving and removing loose pollutants, and the mechanical beating is focused on breaking and knocking off stubborn blockages that are firmly adhered and hard to be removed. The synergistic effect not only realizes the deep cleaning of the filter plate 801 from the surface to the micro pores, so as to fundamentally solve the blockage problem, but also generates strong shock waves through periodic beating, which can effectively destroy the structural force inside the pollutants, so as to make them loose and peeled.
