Flue gas pipeline spraying cooling system

Abstract

The invention relates to a cooling system, in particular to a flue gas pipeline spraying cooling system used for a cement plant. The flue gas pipeline spraying cooling system comprises an integrated pump station, a flue gas pipeline, atomization spray guns, a grouping control box, a speed sensor, temperature sensors, a pressure sensor and connecting pipelines, wherein the flue gas pipeline serves as a cooling carrier, the temperature sensors are arranged at an inlet and an outlet of the flue gas pipeline correspondingly, and the atomization spray guns are fixed on the upper portion of the flue gas pipeline; the integrated pump station is provided with a control unit, an inlet is connected with a clear water pipeline and a compressed air pipeline, and an outlet is connected with an inlet of the group control box; an outlet of the group control box is connected with the atomization spray guns; and the pipelines are adopted for connection of all parts. The flue gas pipeline is used as the cooling carrier, so that the cost is reduced; the atomization spray guns operating with the low pressure are adopted, so that energy saving and consumption reduction are achieved; and adjustment is conducted through an automatic control system, using is convenient, and reliability is high.

Description

technical field [0001] The invention relates to a cooling system, in particular to a flue gas pipeline spray cooling system used in a cement plant. Background technique [0002] The new dry process cement clinker production equipment has been localized and mature, but most of the systems used to cool the flue gas at the kiln tail still use the method of humidifying towers with high-pressure return spray guns. The investment cost of humidifying towers is high, and the use of High-pressure return spray guns require a large number, high pressure during operation, instability, and unstable atomization quality when adjusting the flow rate, and the "wet bottom" phenomenon of the humidifying tower is prone to occur. Some cement plants adopt cooling systems imported from abroad, but the purchase cost is high, and the cost of spare parts is high, which is not conducive to popularization.
