Abstract

The invention provides a control device for the temperature at an outlet of a humidifying tower in a cement plant. The control device mainly consists of an atomization nozzle, a water source, a gas source, a temperature sensor and a control system, wherein the control system automatically adjusts the opening degree of a water path valve and a gas circuit valve according to the comparison between the temperature signals transmitted by the temperature sensor and a set value, and the atomization nozzle sprays water mists, so that the temperature of gas in the tower is reduced, and the temperature of gas at the outlet of the humidifying tower is kept in the set range. The device works automatically, can accurately control the temperature of gas at the outlet of the humidifying tower, meets the work demands of the follow-up work sections, and is high in degree of automation and safe and convenient in operation.

Description

technical field [0001] The invention relates to the technical field of cement production, in particular to a temperature control device for the outlet of a humidification tower in cement production. Background technique [0002] In the dry cement production technology, the preheater will generate a large amount of high-temperature flue gas. The main function of the humidification tower in the cement production process is to humidify the high-temperature flue gas at the tail of the dry kiln to reduce the high-temperature dust in the exhaust gas. The specific resistance improves the efficiency of electric dust collection at the kiln tail, protects the environment, recycles dust, and reduces material consumption; lowers the temperature to meet the operation requirements of subsequent process equipment. [0003] It can be seen from the cement process design in recent years that the role of the humidifying tower is becoming more and more important. It plays the role of humidific...
