Quenching device with air taking structure and design method of air taking structure

Abstract

The invention relates to a quenching device with an air taking structure and a design method of the air taking structure. The quenching device comprises a quenching chamber and an air taking chamber; the quenching chamber comprises a volute-shaped shell, an air inlet pipe, an air outlet pipe and a blast pipe; the air inlet pipe and the air outlet pipe are located on the two sides of the circle center of the shell and fixedly connected with the shell; the blast pipe and the shell are tangent and fixedly connected; an air inlet is formed in the air taking chamber, and the end, away from the air inlet, of the air taking chamber is fixedly connected with a connecting pipe; and the air inlet of the air taking chamber is connected with a smoke chamber of a cement kiln, and the connecting pipe is connected with the air inlet pipe. The design method comprises the following steps of S1, arranging a table; S2, calculating an average particle size index; and S3, carrying out a simulation experiment. The quenching device has the effect of improving the dechlorination efficiency.

Description

technical field [0001] The application relates to the technical field of cement production equipment, in particular to a quenching device with an air intake structure and a design method for the air intake structure. Background technique [0002] In the cement production process, the raw materials contain highly volatile components such as alkali, sulfur, and chlorine. These highly volatile components will cause skinning and blockage during the production process, thereby affecting the normal operation of the cement kiln system. Therefore, in the process of cement production In the process, the bypass ventilation process must be adopted to solve the skinning and blockage in the system. Bypass venting process refers to releasing part of the kiln gas at the kiln tail smoke chamber to destroy the circulation of the above-mentioned high volatile components in the system, thereby effectively reducing the content of alkali, chlorine and sulfur in the clinker, thereby preventing th...

Problems solved by technology

[0005] In view of the above-mentioned related technologies, the inventor believes that the bypass windproof system of the cement kiln is not efficient in capturing small particles in the raw meal during the process of discharging the kiln gas, and most of the chloride ions in the kiln gas will be attached to the The surface of the raw meal, so the inability to capture small particles will affect the specific surface area, resulting in a very low discharge rate of chloride ions
