Abstract
The utility model provides a device for controlling outlet temperature of a humidifying tower in a cement plant. The device mainly comprises an atomizing nozzle, a water source, a gas source, a temperature sensor and a control system, wherein the control system regulates the opening degrees of valves of a water path and a gas path automatically by comparing a temperature signal sent back by the temperature sensor with a set value so as to make the atomizing nozzle spray water fog to reduce the gas temperature in the tower, so that the gas temperature at the outlet of the humidifying tower is kept in a set range. The device works fully automatically, can control the gas temperature at the outlet of the humidifying tower accurately to meet the operating requirements of sequent working sections, and is highly automatic and safe and convenient to operate.
Description
Technical field
The utility model relates to the technology of producing cement field, especially relates to conditioning Tower outlet temperature control device in a kind of manufacture of cement.
Background technology
In the cement dry method production technology, primary heater can produce a large amount of high-temperature flue gas, conditioning Tower significant feature on cement production process is dry method kiln kiln tail high-temperature flue gas to be carried out humidification handle, high-temperature dust compares resistance in the reduction waste gas, improve the kiln tail electricity work efficiency of gathering dust, the protection environment reclaims dust, reduces supplies consumption; Reduce temperature, reach subsequent technique equipment operation demand.
As can be seen, the effect of conditioning Tower is more and more important from the design of cement industry in recent years.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 exhaust gas temperature 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 by manual 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 purpose of this utility model is in order to solve the stable control of conditioning Tower outlet temperature in the manufacture of cement, a kind of cement mill conditioning Tower outlet temperature control device to be provided.
A kind of cement mill 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 reserve tank by the running water pipe automatic water-supply, and source of the gas is an air lift pump, or the gas-holder 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 utility model is a conditioning Tower temperature control equipment in a kind of manufacture of cement, and the control principle of this device is:
1.1 the temperature signal at conditioning Tower gas access, outlet position is gathered in data acquisition;
1.2 design temperature is set the design temperature that conditioning Tower gas vent position will reach;
1.3 design temperature is compared with scene temperature, if scene temperature is higher than design temperature, the PLC controller is then opened gas circuit, water route electric gate valve, in conditioning Tower, spray into steam, atomized steam runs into high-temperature flue gas in the tower, moment is changed vapours into, on flue gas particle, and the effect of reach cooling, gathering dust; When if scene temperature is lower than design temperature, then atomizer stops spraying automatically.
The beneficial effects of the utility model are that this installs fully automatic operation, can control the conditioning Tower Outlet Gas Temperature accurately, satisfies the operation needs of follow-up workshop section, automaticity height, handling safety, convenience.
