The invention provides a tower-type gas-liquid contact equipment even gas distribution device and an application thereof. The device sequentially comprises a tower body, a gas distribution disk, a resistance layer and an air chamber from top to bottom; the gas distribution disk is horizontally arranged on the lower portion of the tower body, vertical pore passages which penetrate through a base body of the gas distribution disk is formed in the base body, circular straight pipes are inserted into the vertical pore passages, and the outer walls of the circular straight pipes and the inner walls of the pore passages are sealed; the resistance layer is composed of two or more hollow cylinders and solid particle filler; the solid particle filler is wrapped with fabric and central cylinder cavities and annular cavities formed through hollow cylinders are filled with the solid particle filler; the air chamber is located in a cone-shaped cavity which is formed in the lower portion of the resistance layer and connected with the tower body. By means of the tower-type gas-liquid contact equipment even gas distribution device, due to the fact that the resistance of the gas chamber is increased, even distribution of bubbles in the cross section of the tower body is achieved, and the diameters of the bubbles are uniform.
