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
The present invention relates to the technology of producing cement field, especially relate to conditioning Tower outlet temperature control device in a kind of manufacture of cement.
Background technology
In the cement dry method production technology; Preheater can produce the great amount of high-temperature flue gas, and conditioning Tower significant feature on cement production process is dry method kiln kiln tail high-temperature flue gas to be carried out humidification handle, and high-temperature dust compares resistance in the reduction waste gas; Improve the kiln tail electricity operating efficiency of gathering dust; The protection environment reclaims dust, reduces supplies consumption; Reduce temperature, reach subsequent technique equipment operation demand.
From cement industry design in recent years, can find out that the effect of conditioning Tower is more and more important.Brought into play humidification and also played and go into to grind the hot blast regulating action, according to the needs and the operation conditions of raw material stoving formula Vertical Mill, control conditioning Tower injection flow rate is regulated the conditioning Tower outlet temperature, guarantees that EGT can be between 170 ℃-300 ℃.
The humidification control of conditioning Tower is the big difficult point of one in the cement production process always.At present often through Artificial Control, the workman imports and exports the variation of gas temperature according to conditioning Tower, by rule of thumb, feel to regulate the injection flow rate of conditioning Tower spraying apparatus.The frequent start-stop that has so just caused spraying apparatus, the outlet temperature fluctuation rises and falls big.
Summary of the invention
The objective of the invention is provides a kind of cement plant conditioning Tower outlet temperature control device in order to solve the stable control of conditioning Tower outlet temperature in the manufacture of cement.
A kind of cement plant conditioning Tower outlet temperature control device, form by following each several part:
1. be installed in the atomizing lance of conditioning Tower gas access portion, be used to produce atomized steam;
2. the conditioning Tower spraying system that is connected with above-mentioned atomizing lance water inlet comprises water source and source of the gas;
3. be installed in the temperature sensor at conditioning Tower gas access, outlet position;
4. control the temperature control system of water supply and air feed automatically according to the temperature sensor temperature signal.
Conditioning Tower spraying system recited above comprises water source and source of the gas, and the water source is a storage tank by the running water pipe automatic water-supply, and source of the gas is a pulsometer, or the air accumulator by factory's air feed.
Temperature control system recited above is made up of Temperature Treatment module, analog quantity expansion module, PLC controller and touch-screen; The Temperature Treatment module is connected with the temperature sensor at conditioning Tower gas access, outlet position, and each control end of PLC controller links to each other with water valve with the air valve of above-mentioned conditioning Tower spraying system.
The present invention is a conditioning Tower temperature control equipment in a kind of manufacture of cement, and the control principle of this device is:
