[0018] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0019] As Figure 1 And Figure 2 As shown in the drawings, according to the embodiments of the present application, a kind of liquid distributor is provided, including distribution groove one 1 and distribution groove two 2 by communication groove 3 communication, the length of distribution groove one 1 is greater than the length of distribution groove two 2;Distribution groove one 1 and distribution groove two 2 are provided with two rows of distribution holes 4 in front and back sides along the up and down direction, and two rows of distribution holes 4 are staggered.

[0020] By setting two rows of distribution holes, the operation flexibility of liquid distributor can be improved, and the staggered distribution holes can make the liquid distribution more uniform;When operating load is in the small load range of 30%-80%, the liquid level in the liquid distributor is located between the lower distribution hole and the upper distribution hole, and the liquid distributor uses only the lower distribution hole to distribute liquid at this time;When operating load is in the large load range of 80%-160%, the liquid level in the liquid distributor is located above the upper distribution hole, and the liquid distributor uses the upper and lower holes to distribute liquid at this time.

[0021] Both the front and rear sides of distribution tank 1 and distribution tank 2 are provided with baffles 5 to guide the liquid distributed from the distribution hole 4; the bottom of the baffles 5 is provided with serrations 6 for guiding the liquid.

[0022] The liquid is sprayed out from the distribution hole 4, sprayed onto the baffle plate 5, flows down along the baffle plate 5, and finally falls along the tip of the serration 6, which is more conducive to the uniform distribution of the liquid.

[0023] The top openings of distribution groove 1, distribution groove 2 and connecting groove 3 are provided, and a reinforcing plate 8 is provided at the top of distribution groove 1 and between distribution groove 1 and distribution groove 2.

[0024] like Figure 3 As shown, this embodiment also provides a packed tower, including a tower body 7, packing and the liquid distributor mentioned above. Multiple liquid distributors are distributed inside the tower body 7. Distribution channel 2 in the same liquid distributor is closer to the inner wall of the tower body 7, and distribution channel 1 is closer to the center of the tower body 7. The packing is located below the liquid distributor.

[0025] The liquid capacity of the distributor is increased by setting up distribution tank one and distribution tank two; the length of distribution tank one is greater than the length of distribution tank two, which allows the distributor to be better integrated with the tower body, making the liquid distribution in the entire tower body more uniform.

[0026] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
