Drainage filtering type liquid distributor

Abstract

The invention discloses a drainage filtering type liquid distributor, which comprises a drainage assembly, a liquid inlet pipe, a filtering assembly and a cleaning assembly, wherein the liquid inlet pipe is communicated with a liquid storage tank, a first annular groove body is fixed in the liquid storage tank and is communicated with a liquid outlet hole, a liquid distribution box is rotationallyconnected to the lower part of the liquid storage box and is communicated with the liquid outlet hole, a filtering barrel is located in the liquid outlet hole and extends into the liquid distributionbox, the filtering barrel is provided with an annular boss, the annular boss abuts against the first annular groove body, a second annular groove body is fixed in the liquid distribution box and located below the filtering barrel, and a plurality of first flow distribution components are communicated with the liquid distribution box and located below the liquid distribution box; a first filter screen and a second filter screen are arranged in the filtering barrel up and down; liquid is precipitated, filtered and drained for multiple times; and two moving components slide along with the movingplate to extend into sliding grooves and abut against the annular boss to replace the first filter screen and the second filter screen, and the filtering and draining effect is improved, so that thequality and efficiency of mass transfer contact reaction are improved, and then the quality of a final finished product is improved.

Description

technical field [0001] The invention relates to the technical field of packed tower distributors, in particular to a drainage filter type liquid distributor. Background technique [0002] The packed tower is a mass transfer device in which the packing in the tower is used as a contact member between the gas and liquid phases. The tower body of the packed tower is a vertical cylinder, and the bottom is equipped with a packing support plate. The packing is placed on the support plate in a random pile or a whole way, and a packing pressure plate is installed above the packing to prevent it from being blown by the updraft. The liquid is sprayed onto the filler from the top of the tower through the liquid distributor, and flows down along the surface of the filler. The gas is fed from the bottom of the tower, and after being distributed by the gas distribution device, it flows countercurrently with the liquid and continuously passes through the gap of the packing layer. On the s...

Problems solved by technology

[0004] The purpose of the present invention is to provide a drainage filter type liquid distributor, which aims to solve the problem that the existing liquid distributor only passes through a single filter screen and drainage tube to filter and drain to the filler for mass transfer contact reaction, the mass transfer effect is poor, and then Problems that lead to poor quality of the final product
