Description
Technical field
The present invention relates to the cement process equipment, especially refer to utilize the waste heat of cement clinker cooler to make water heater, promptly in manufacture of cement, utilized the water heater of grog waste heat as thermal source.
Background technology
The cement cooler is the indispensable important corollary equipment of cement rotary kiln, its purposes is that the high temperature chamotte that rotary kiln draws off is cooled to downstream conveyor, storage vault, and the temperature that can bear of cement grinding mill, simultaneously the high temperature chamotte sensible heat is reclaimed into firing system, improve the thermal efficiency of whole firing system.
The cooling effectiveness of castor formula cooler is the highest in the chamotte cooler form.Many typhoons machine is blown into cold wind in castor formula cooler, through overshoot and conduction heat exchange, clinker temperature drops to 85 ℃ from 1000 ℃ and goes into storage vault, and cooling air then is heated to 900 ℃ from environment temperature and goes into rotary kiln, and cooler air draft exhaust gas flow is 125000Nm
3/ h, delivery temperature is 250 ℃, has surplus heat to utilize.
Along with the China's economy development, energy problem becomes increasingly conspicuous, the invention residue heat water heater, can fully utilize the cement producing line waste heat resource on the one hand, the heat that reclaims high-temperature flue gas makes it to turn waste into wealth, reduce the manufacture of cement cost and improve economic benefit of enterprises, improve the competitiveness of enterprise; Delivery temperature, energy savings be can reduce on the other hand, air pollution and greenhouse effects also can be reduced environment.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of exhaust heat that utilizes chamotte cooler as heating carrier, thermal efficiency height, energy-conservation water heater using waste heat of cement clinker cooling machine, and can save coal-burning boiler.
The present invention solves the problems of the technologies described above the technical scheme of being taked: water heater using waste heat of cement clinker cooling machine of the present invention, control by microcontroller, comprise the magnetic floating-ball fluid level transmitter, temperature controller, boiler, tubing pump and coil pipe, characteristics are: the coil pipe of water heater is installed in the chamotte cooler, coil pipe is connected with boiler with outlet pipe by water inlet pipe, in the water inlet pipe of coil pipe, be serially connected with a tubing pump, the coil pipe of forcing water to circulate through being installed in the chamotte cooler adds hot water gradually, in the outlet pipe of coil pipe, be serially connected with a safety valve, anti-sealing is overheated, and to become steam accidents caused, top one side of boiler connects cold water inlet and cold water entering water electromagnetic valve, the opposite side bottom of boiler connects outlet pipe and hot water effluent's valve, and magnetic floating-ball fluid level transmitter and temperature controller are housed on boiler.
Adopt the magnetic floating-ball fluid level transmitter, this fluid level transmitter is made up of sensor and converter two parts.According to ball float principle and magnetic couplings action principle, when the fluctuation in stage in the boiler, float in the fluid level transmitter main pipe is lifting thereupon also, permanent-magnet steel in the float is delivered to sensor by magnetic coupling, the converter part converts the voltage signal of sensor to standard analog signal output, the microcontroller interface carries out routine processes to detected analog signal, produces required output then.
Temperature controller then becomes electric current output to the detected analog-signal transitions of water temperature measuring device, by the laggard line program control of microcontroller digitized processing, produces required output.
When the boiler water level reaches high water level (apart from 20 centimetres of hot water tank tops), microcontroller can cut off the cold water moisturizing automatically; When the boiler water level near low water level (20 centimetres) apart from boiler bottom, microcontroller then replenishes cold water automatically.When the boiler water temperature reaches 75 ℃, then the tubing pump of coil pipe quits work automatically, stops water circulation heating; When the boiler water temperature is lower than 55 ℃, then (1) when water temperature meets the demands the tubing pump of coil pipe open automatically; (2) the water level tubing pump that is lower than control water level coil pipe quits work automatically and replenishes cold water automatically.
The invention has the beneficial effects as follows:
1, as long as cement rotary kiln runs well, the cement clinker cooler operate as normal, residue heat water heater just can provide a certain amount of hot water, does not need electrical heating or coal-fired heating;
2, comprehensive utilization cement producing line waste heat resource reduces the manufacture of cement cost;
3, reduce delivery temperature, saved coal-burning boiler, energy savings;
4, minimizing is to the air pollution and the greenhouse effects of environment.
