Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0017] Embodiment: Refer to Figures 1-4, a demisting device for a desalination four-effect evaporation chamber with a clogging prevention function in the present utility model, includes a positioning ring plate 1, which facilitates the connection of an L-shaped connecting plate 2 and a connecting frame 4; both sides of the top surface of the positioning ring plate 1 are longitudinally provided with L-shaped connecting plates 2, which facilitate the fixation of the device in the evaporation chamber; both ends of the L-shaped connecting plate 2 are provided with positioning openings, and fixing bolts 3 are arranged in the positioning openings, which facilitate the fixation of the L-shaped connecting plate 2 in the evaporation chamber; and a demisting component is arranged inside the positioning ring plate 1; the demisting component includes a connecting frame 4 arranged inside the positioning ring plate 1, which facilitates the connection of a supporting ring plate 6; the connecting frame 4 and the positioning ring plate 1 are in the same horizontal plane, and an elastic metal mesh 5 is arranged at the lower end of the connecting frame 4, which facilitates the support of a wire mesh 11; the outer side of the elastic metal mesh 5 is fixedly connected with a supporting ring plate 6, which facilitates the connection of the elastic metal mesh 5 and the supporting wire mesh 11.

[0018] In the present utility model, a plurality of equally spaced connecting openings are provided on the top surface of the connecting frame 4, and a fixing screw 7 and an adjusting screw 8 are respectively arranged vertically in the connecting openings, which facilitate the connection of the elastic metal mesh 5 through the fixing screw 7 and the adjustment of the height of the middle part of the elastic metal mesh 5 through the adjusting screw 8 to avoid the clogging of the wire mesh 11; the fixing screw 7 is arranged in the connecting opening provided on the peripheral side of the connecting frame 4, the adjusting screw 8 is arranged in the connecting opening provided in the middle of the top surface of the connecting frame 4, and the lower ends of the fixing screw 7 and the adjusting screw 8 are fixedly connected with the elastic metal mesh 5; an adjusting nut 9 is arranged in the middle of the top surface of the connecting frame 4, which facilitates the fixation of the adjusting screw 8; and a plurality of equally spaced positioning nuts 10 are arranged on the peripheral side of the top surface of the connecting frame 4, which facilitate the positioning of the fixing screw 7; the adjusting nut 9 is threadedly connected with the adjusting screw 8, and the positioning nut 10 is threadedly connected with the fixing screw 7; a wire mesh 11 is arranged between the connecting frame 4 and the elastic metal mesh 5, which facilitates demisting; the top surface of the wire mesh 11 abuts against the bottom surface of the positioning ring plate 1, and the bottom surface of the wire mesh 11 abuts against the top surface of the supporting ring plate 6.

[0019] Working principle: When the present utility model is in use, first place the wire mesh 11 on the top surfaces of the elastic metal mesh 5 and the supporting ring plate 6. At this time, the upper ends of the fixing screw 7 and the adjusting screw 8 penetrate through the wire mesh 11. Then, align the connection ports opened on the connecting frame 4 inside the positioning ring plate 1 with the fixing screw 7 and the adjusting screw 8 and press them down. Then connect the adjusting nut 9 and the positioning nut 10 to the adjusting screw 8 and the fixing screw 7 respectively. After the positioning nut 10 is connected to the fixing screw 7, rotate the adjusting nut 9. Due to the threaded connection between the adjusting nut 9 and the adjusting screw 8, when the adjusting nut 9 rotates, the adjusting screw 8 is controlled to rise. At this time, the middle part of the lower elastic metal mesh 5 will rise, thereby controlling the bottom surface of the wire mesh 11 to sink inward. Then install the device on the upper end of the evaporation chamber through the fixing bolt 3; start the evaporation chamber. The wire mesh 11 intercepts the foam generated by the evaporated liquid. When the foam contacts the wire mesh 11, the foam will turn into liquid. Then, due to the inward depression of the bottom surface of the wire mesh 11, the liquid will flow to the outside of the wire mesh 11 through capillary action and then return to the evaporation chamber, thereby preventing the foam from blocking the wire mesh 11 and avoiding high steam consumption caused by repeated cyclic evaporation.

Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
