[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments in this application specification, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection claimed in this application.
[0031] In the description of the embodiments of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0032] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a replaceable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.
[0033] Please see Figure 1 In the first aspect of this application, an outlet flue ash discharge structure is provided, including: an outlet flue 10 and a lower ash pipe 20; the lower ash pipe 20 is connected to the middle part of the outlet flue 10; a first valve 21 is provided on the lower ash pipe 20; the first valve 21 is used to control the opening and closing of the lower ash pipe 20, and can close the lower ash pipe 20 when needed.
[0034] In this design, the two ends of the outlet flue 10 can be connected to the reaction tower and the dust collector, respectively, to transport the reacted fumes to the dust collector for dust removal. During the transport of the fumes through the outlet flue 10, they gradually accumulate at the bottom of the outlet flue 10. By connecting the ash discharge pipe 20 in the middle of the outlet flue 10, the ash deposited at the bottom of the outlet flue 10 can be discharged, preventing blockage of the outlet flue 10.
[0035] In practical applications, the outlet flue 10 is generally set horizontally; in this embodiment, the outlet flue 10 can be set as a downward-recessed V-shape, and correspondingly, the ash discharge pipe 20 is set in the recess of the outlet flue 10, which can effectively discharge the accumulated ash.
[0036] It should be noted that in practical applications, the smoke after dust removal by the dust collector will be discharged through the chimney, and the ash generated by the dust collector will enter the ash conveyor; therefore, the ash discharge pipe 20 in this embodiment can be directly connected to the ash conveyor.
[0037] In practical applications, the ash discharge pipe 20 is set vertically or inclined downwards, which helps the ash material to be discharged through the ash discharge pipe 20.
[0038] In this embodiment, corresponding to the setting of the first valve 21, a material height sensor can be installed in the outlet flue 10; the material height sensor can be an infrared sensor or the like, used to sense the height of the ash material accumulated in the outlet flue 10; when the material height sensor senses that the ash material in the outlet flue 10 has reached a certain height, the first valve 21 is opened.
[0039] In a further improved embodiment, a second valve 22 is also provided on the lower ash pipe 20; the first valve 21 and the second valve 22 are spaced apart along the flow direction of the lower ash pipe 20.
[0040] The following description describes the flow of the gray pipe 20 from top to bottom, with the first valve 21 located above the second valve 22.
[0041] By setting up a first valve 21 and a second valve 22, the problem of excessive ash material clogging the valves can be avoided. Specifically, when there is too much ash material above the first valve 21, the first valve 21 can be closed first, and then the second valve 22 can be opened. At this time, the amount of ash that the second valve 22 needs to discharge is only the amount of ash between the first valve 21 and the second valve 22, thus avoiding the second valve 22 from being blocked. Afterwards, by opening the first valve 21 intermittently, the ash material can be quantitatively or in small amounts transferred to the second valve 22 for discharge.
[0042] In a more specific embodiment, the first valve 21 located at the top is a slide gate valve.
[0043] When ash accumulates at the location of the first valve 21, the ash can be pushed and discharged by the push and pull of the slide valve structure, thereby pushing the accumulated ash and further preventing the first valve 21 and the second valve 22 from becoming blocked.
[0044] Correspondingly, the first valve 21 and the second valve 22 can be electric valves or manual valves, without restriction.
[0045] In one embodiment, it further includes: a feeding hopper 30; the feeding hopper 30 is disposed between the outlet flue 10 and the ash discharge pipe 20; the ash discharge pipe 20 is connected to the outlet flue 10 through the feeding hopper 30.
[0046] The feed hopper 30 is used to collect ash material, which helps to discharge the ash material better.
[0047] As one implementation method, the hopper 30 is a semi-circular hopper, which has good support and helps the ash material slide down.
[0048] Furthermore, the lower ash pipe 20 is covered with an insulation layer.
[0049] Specifically, the inventors discovered that the temperature of the ash material is related to its fluidity. Therefore, covering the outer periphery of the ash discharge pipe 20 with an insulation layer helps maintain the fluidity of the ash material, thereby facilitating better ash discharge.
[0050] A second aspect of this application provides a reaction tower system, including the outlet flue ash discharge structure of any of the above.
[0051] Specifically, such as Figure 2 As shown, the reaction tower structure may include a reaction tower 100, a dust collector 200, and an ash conveyor 300; one end of the outlet flue 10 in the outlet flue ash discharge structure is connected to the reaction tower 100, and the other end is connected to the dust collector 200; the end of the ash discharge pipe 20 in the outlet flue ash discharge structure away from the outlet flue 10 is connected to the ash conveyor 300.
[0052] The end of the ash discharge pipe 20 away from the outlet flue 10 can be connected to the ash conveying pipe 310 of the ash conveyor 300, and scraped into the ash conveyor 300 by the scraper in the ash conveying pipe 310.
[0053] In one embodiment, the reaction tower 100 is provided with a feed inlet and a discharge outlet; the feed inlet is located above the discharge outlet.
[0054] In this embodiment, the smoke entering the reaction tower 100 has an upward flow path structure to ensure that the smoke fully reacts with the deacidification structure in the reaction tower 100.
[0055] The above are merely preferred embodiments of this application and are not intended to limit the present invention. Although the present application has been described in detail with reference to examples, those skilled in the art can still modify the technical solutions described in the foregoing examples or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
