[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0022] Reference Figures 1-3A water supply device for an exhaust gas washing tower comprises a water supply mechanism installed inside a washing tower body 1, the water supply mechanism comprises a limiter 3, a water inlet port 5, an annular pipe 6, a water pipe 7, a toggle shaft 8 and a nozzle 9, the limiter 3 is a plurality of groups fixed around the inside of the washing tower body 1, the annular pipe 6 is movably installed on the plurality of limiters 3, the water inlet port 5 is fixed to the inner wall of the washing tower body 1 through a fixing rod 4, and the water inlet port 5 is connected to a water inlet 10 at the annular pipe 6 through a water pipe 7, the toggle shaft 8 and the nozzle 9 are both a plurality of groups, and are staggeredly installed at the inner circle of the annular pipe 6, and the nozzle 9 is connected to the annular pipe 6;

[0023] A closing cover 2 is provided at the height of the annular tube 6 corresponding to the washing tower body 1, and the height of the annular tube 6 is located at the middle and lower end position of the closing cover 2; the water supply mechanism as a whole is horizontally installed on the inner wall of the washing tower body 1, and the annular tube 6 is located at the lower end position of the closing cover 2. After opening the closing cover 2, the staff has enough space to reach into the washing tower body 1 and rotate the annular tube 6 to adjust the position, and move the nozzle 9 that needs to be replaced to the position of the closing cover 2, which is convenient for the staff to maintain.

[0024] The limiting part 3 includes a limiting block 301, a rubber pad 302 and a ball 303. One side of the limiting block 301 is provided with an arc-shaped opening, and the rubber pad 302 is installed at both ends of the arc-shaped opening of the limiting block 301. There are multiple balls 303 arranged on the inner side of the arc-shaped opening; the annular tube 6 is embedded in the arc-shaped opening of the limiting block 301 and is matched with the arc-shaped opening. The rubber pad 302 can play a protective role. During the movement of the annular tube 6, the rubber pad 302 can wipe off the water stains on the annular tube 6, reduce the contact between the ball 303 and the water stains, and ensure the normal rotation of the ball 303.

[0025] The ball 303 and the rubber pad 302 can be set in contact with the annular tube 6 at the same time; the rubber pad 302 can wipe off the water stains on the annular tube 6, and the ball 303 fits on the annular tube 6. Through the rotation of the ball 303 itself, the friction force on the annular tube 6 is reduced, so that the annular tube 6 can move stably.

[0026] The water inlet port 5 is arranged on the vertical center axis of the annular tube 6; because the water inlet port 5 is connected with the water inlet 10 on the annular tube 6 through the water pipe 7, the external water pump is connected with the water inlet port 5 through an external pipeline, and the purified water is transported from the water inlet port 5 along the water pipe 7 to the annular tube 6, and sprayed through the toggle shaft 8, so as to further purify the exhaust gas inside the washing tower body 1. After long-term use, the nozzle 9 is easy to be blocked, and the annular tube 6 can rotate one circle, so as to facilitate the maintenance of the nozzle 9 by the staff.

[0027] The device can open the closing cover 2, and push the toggle shaft 8 to push the annular tube 6 to rotate on the limiting portion 3, so that the nozzle 9 on the annular tube 6 that needs to be repaired and replaced can be moved to the closing cover 2 and removed. After the repair and replacement is completed, the closing cover 2 can be installed back to the original position.

[0028] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
