Problems solved by technology

The control method of the grate cooler in the above-mentioned patent has the following disadvantages: when adjusting the control, only the single variable of pressure is used, and the influence of other factors on the cooling of the clinker is not considered, and the factors that change the pressure are not only There is a thickness of the material layer, so there is still the problem of few factors to be referred to for adjustment and control

Abstract

The invention discloses a cement clinker gate cooler control method, relates to the technical field of cement clinker cooling, and aims to solve the problem of less adjustment reference factors. Specifically, the cement clinker gate cooler control method comprises a basic setting module, a real-time data module, an analog indication module, a confirmation module, a sending module and an executionmodule, wherein the real-time data module comprises data of exhaust gas temperature, material layer thickness, pressure under a gate, gate bed speed, fan capacity, gate plate temperature and clinker temperature; the basic setting module comprises air humidity pressure range, adjusting amplitude and adjustable scaling; and the execution module comprises cooling fan adjustment and transportation speed adjustment. According to the control method, by arranging multiple detection aspects of exhaust gas temperature, material layer thickness, pressure under a gate, clinker temperature and the like, the operating state of the whole equipment is monitored, the reference data is more comprehensive when the equipment is further adjusted, and adjustment can be performed without only depending on the pressure under a gate; and by virtue of the comprehensive operating date, the adjustment and cooling effect of the gate cooler is better.

Description

technical field [0001] The invention relates to the technical field of cement clinker cooling, in particular to a control method for a cement clinker grate cooler. Background technique [0002] The grate cooler is one of the main equipment in the cement clinker firing process in the new dry process cement production line. It is responsible for the rapid cooling of the high-temperature clinker and the recovery of the heat carried by the clinker. The clinker cooling system of the cement kiln requires Maintain a certain material layer thickness in order to obtain stable wind temperature and other process parameters, and meet the rapid cooling of clinker to achieve the purpose of improving product quality. [0003] After retrieval, the Chinese patent application number is CN104896953B, which discloses a control method and system for a cement kiln grate cooler. The method includes the following steps: obtaining basic parameter values, which include cement kiln grate cooler The l...
