The invention discloses a casting-type liquid distributor. The casting-type liquid distributor is composed of a liquid inlet pipe, conical liquid stopping plates and a plurality of liquid distributing plates. A plurality of connecting pieces are arranged between the conical liquid stopping plates and the liquid distributing plates and between all the liquid distributing plates, and are evenly arranged along the circumference, and the conical liquid stopping plates are fixedly connected with all the liquid distributing plates through the connecting pieces; all the liquid distributing plates are circular plates, circular liquid through holes are drilled in the centers of all the liquid distributing plates, all the liquid distributing plates are arranged at intervals from top to bottom, and the diameter of all the liquid distributing plates and the diameter of liquid through holes in the liquid distributing plates are gradually decreased from top to bottom. By means of the casting-type liquid distributor, liquid can be distributed in a horizontal spraying mode through the multiple liquid distributing plates, and can be distributed to form a plurality of paraboloid liquid membranes, liquid distributing is even and large in size, blocking is not prone to being caused and gas-liquid-contacting mass and heat transferring can be achieved.
