[0019] The following will describe in detail the implementation of the present invention with reference to the accompanying drawings and embodiments, so that the process of how the present invention uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0020] In the description of this invention, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention 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. They should not be construed as limiting the specific protection scope of this invention.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature, and in the description of this invention, "a number" means two or more, unless otherwise explicitly specified.

[0022] In this invention, unless otherwise explicitly specified and limited, the terms "assembly," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or 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 this invention according to the specific circumstances.

[0023] It should be understood that, when used in this specification and the appended claims, the terms "comprising" and "including" indicate the presence of the described features, integrals, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or collections thereof.

[0024] It should also be understood that the terminology used in this specification of embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of the invention. As used in this specification of embodiments of the invention and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0025] As shown in the accompanying drawings, a purification tower nozzle includes a nozzle body 2 and a dredging assembly. The nozzle body 2 is provided with a flow channel 7 for liquid to flow through, and one end of the nozzle body 2 is provided with a spray port 1 that communicates with the flow channel 7. The unblocking component is located inside the nozzle body 2. When the spray port 1 is blocked, the pressure in the flow channel 7 increases. Under the action of the increased pressure, the unblocking component is inserted into the spray port 1 to unblock the spray port 1.

[0026] In the above solution, by setting up a dredging component, when the spray nozzle is blocked, the pressure in the flow channel increases. Under the action of the increased pressure, the dredging component is inserted into the spray nozzle to dredge it, thereby effectively preventing the spray nozzle from becoming blocked and ensuring the purification effect on the flue gas.

[0027] In another embodiment of the present invention, the unblocking assembly includes a pressure detection mechanism and an unblocking mechanism. The pressure detection mechanism is used to detect the pressure inside the nozzle body 2. The unblocking mechanism is drivenly connected to the pressure detection mechanism. When the pressure detection mechanism detects an increase in pressure inside the flow channel 7, it drives the unblocking mechanism to unblock the spray nozzle 1. Specifically, the pressure detection mechanism includes a pressure-bearing ring 5 and several detection components. The pressure-bearing ring 5 is disposed inside the flow channel 7. The detection components include a spring 8 and a connecting member. The nozzle body 2 is provided with a movable cavity 9. The spring 8 is disposed inside the movable cavity 9. One end of the connecting member is fixedly connected to the pressure-bearing ring 5, and the other end passes through the movable cavity 9 and is fixedly connected to the spring 8.

[0028] The connecting component includes a connecting rod 6 and a piston head 11. The connecting rod 6 is fixedly connected to the piston head 11. A sealing ring 10 is provided on the outer circumferential surface of the piston head 11. The movable cavity 9 is a cylindrical cavity that matches the shape of the piston head 11.

[0029] It should be noted that, in order to prevent the piston head from compressing the air pressure in the active chamber during its movement, which would cause the air pressure in the active chamber to increase and affect the movement of the piston head, a vent hole 4 is provided in the nozzle body 2. One end of the vent hole 4 is connected to the active chamber 9, and the other end is connected to the outside. When the piston head is running in the active chamber, outside air is drawn into the active chamber through the vent hole or the air pressure in the active chamber is forced out of the active chamber, thereby making the movement of the piston head smoother and preventing the gas pressure in the active chamber from affecting the pressure detection of the pressure detection device.

[0030] In another embodiment of the present invention, the unblocking mechanism includes an unblocking needle 13 and several fixing rods 12. One end of each fixing rod 12 is connected to a pressure detection mechanism, and the other end is connected to the unblocking needle 13. Specifically, to facilitate the insertion of the unblocking needle into the spray nozzle and improve the unblocking effect on the nozzle, the shape of the unblocking needle 13 is designed to match the shape of the spray nozzle 1, and one end is conical.

[0031] To reduce the liquid pressure in the flow channel and allow the unblocking mechanism to reset after the unblocking needle is inserted into the spray nozzle, an auxiliary spray hole is provided on the unblocking needle 13. This auxiliary spray hole provides auxiliary spraying after the unblocking needle 13 is inserted into the spray nozzle 1, and the spray liquid in the flow channel is ejected from the auxiliary spray hole. Specifically, the auxiliary spray hole includes an axial spray hole 14 and a radial through hole 15. The axial spray hole 14 is axially disposed inside the unblocking needle 13, and the radial through hole 15 is radially disposed on the unblocking needle 13 and communicates with the axial spray hole 14.

[0032] In the above scheme, when the spray nozzle is blocked, the pressure in the flow channel increases. The liquid pressure applied to the pressure ring is greater than the elastic force applied by the spring to the piston head. Therefore, under the action of this pressure difference, the support plate drives the unblocking needle to move towards the spray nozzle until the unblocking needle is inserted into the spray nozzle and removes the impurities blocking it. At the same time, after the unblocking needle is inserted into the spray nozzle, the spray liquid in the flow channel is sprayed out from the auxiliary spray hole, thereby reducing the liquid pressure in the flow channel and causing the unblocking mechanism to reset. The unblocking work of the spray nozzle is completed, and the spray nozzle can work normally. Meanwhile, the support plate returns to its original position under the action of the spring. Through the above scheme, the spray nozzle can be unblocked in time when it is blocked, thus ensuring that the spray nozzle can resume operation in a timely manner. At the same time, the unblocking needle can reduce the area of ​​the flow channel at the unblocking needle, thereby increasing the flow velocity of the spray liquid passing through the unblocking needle and improving the atomization effect of the nozzle.

[0033] In another embodiment of the present invention, in order to facilitate the installation of the nozzle, a mounting flange 3 is provided on the nozzle body 2, and the nozzle can be easily installed on the purification tower through the mounting flange.

[0034] The above description only illustrates the preferred embodiments of the present invention and should not be construed as limiting the scope of the claims. The present invention is not limited to the above embodiments, and variations in its specific structure are permitted. All modifications made within the scope of the independent claims of this invention are also within the scope of protection of this invention.
