A kind of swirl plate column used for producing thiourea

Abstract

The invention discloses a cyclonic plate tower for thiourea production, and belongs to the technical field of thiourea production equipment. The cyclonic plate tower comprises a tower body provided with an induced draft fan at the top, a liquid storage tank placed under the tower body and connected with the tower body. The cyclonic plate tower also comprises a cyclonic plate fixed inside the tower body, a spray nozzle arranged above the cyclonic plate and communicated with the liquid storage tank. The cyclonic plate tower is characterized in that the outer diameter of the cyclonic plate is smaller than the inner diameter of the tower body, and an overflow channel is formed in a cavity between the cyclonic plate and the tower body. The overflow pipes and the overflow grooves with overflow holes are omitted. The cyclonic plate tower is simple in structure, and convenient in installation and maintenance. After the overflow pipe is omitted, the airflow is more stable to avoid the occurrence of turbulence and to ensure that the centrifugal effect of the droplets in the airflow. As the overflow channel is of ring structure, even if some place is blocked by lime nitrogen slurry, the normal production will not be affected, maintenance times is reduced, production efficiency is improved, maintenance cost is saved and maintenance is facilitated.

Description

technical field [0001] The invention belongs to the technical field of chemical equipment and relates to a swirl plate tower, in particular to a swirl plate tower for thiourea production. Background technique [0002] Swirling plate towers are generally used in industrial flue gas desulfurization systems, with structures such as figure 1 As shown, the lower part of the swirl plate tower is a liquid storage tank, and the liquid level above the liquid storage tank is the gas that is passed in. The periphery of the swirl plate in the tower is provided with an annular overflow tank, and an overflow hole is opened on the overflow tank. , there is an overflow pipe connected with the overflow hole under the overflow tank, the outer wall of the overflow tank is fixedly connected with the inner wall of the tower, the upper end of the overflow pipe is connected with the overflow hole to form an overflow channel, and the induced draft at the upper part of the swirl plate tower The opp...
