Description
Technical field
The present invention relates to environmental protection equipment technical field, more particularly to a kind of kiln of utilization dry-process rotory kiln production line rotary kiln
Head height temperature radiations heat energy is by CO2Accumulation of energy is the hot supercritical CO of high pressure2Fluid supplies CO2The CO that generating set generates electricity2Energy storage equipment.
Background technology
It is well known that cement is highly energy-consuming high pollution industry, substantial amounts of discarded waste heat is produced in cement production process, both wave
Taking the energy increases carbon emission, also produces thermal pollution to environment, also results in equipment fault.Kiln head cover and bottom such as cement producing line
The region of the grate-cooler being connected is exactly a high-temperature space.Accept to come from rotary kiln in the equipment in the space and continuously unloaded
1250 DEG C~1450 DEG C high temperature chamotte streams, and 1500 DEG C~1700 DEG C of high temperature spoke of coal injection pipe when retreating to outside kilneye burning
Penetrate heat, and bear in the upward stream of hot air rotary kiln and tertiary-air pipe from 200 DEG C~1350 DEG C of high temperature section in grate-cooler
High temperature gas flow wash away so that kiln head cover inwall refractory material is easy to ablation damage；The clinker of head falls in grate-cooler simultaneously
Material area makes a snowman because high temperature often lumps, or even has to stop kiln cleaning caking at high temperature, has both influenceed kiln system operating mode, influence clinker
Yield, cooling quality, also wasting the energy increases carbon emission, and produces thermal pollution to environment.
On the other hand, with the development of CCS technologies, supercritical carbon dioxide electricity generation system is a kind of with supercriticality
Carbon dioxide has been received significant attention for the Brayton Cycle system of working medium, and supercritical carbon dioxide electricity generation system mainly includes heat
Source, high speed turbine, high-speed engine, high-speed compressor, cooler etc., its high-performance heat exchanger are supercritical generating system engineerings
The basis of application, the circulatory mediator in its cyclic process is carbon dioxide.According to China《Cement》（2014.No.9）《Using CO2
The cement afterheat generation system of power cycle》Introduce, Ohio, USA Akron city Echogen companies are preheated using cement plant
The application CO of the waste gas residual heat design that the waste gas residual heat and chamotte cooler of device discharge are extracted2Power cycle afterheat generating system
（That is the thermal source that Bian is generated electricity with the waste gas residual heat of China's cement production enterprise, but working media is different）, Echogen companies can provide at present
EPS100 8MW heat engine systems waste heat exchanger north America region investment up to 2000~25,000,000 dollars, far above the country
The total investment of 8MW double boilers the whole series afterheat generating system（Domestic cement plant preheater discharges the waste heat boiler and clinker of waste gas
Cooler extracts afterheat boiler electricity-generating system gross investment 4000~60,000,000 yuan of waste gas）, and be objectively difficult to
China's discarded waste heat supply temperature of major part quality coal in cement kiln systems is adapted to raw materials and fuel and the big situation of kiln system fluctuation of operating conditions, and it is efficient
Heat exchanger is the basis of supercritical generating system engineering application.Furthermore, China's cement production enterprise has been popularized and has built up preheater discharge
Waste gas residual heat boiler and chamotte cooler extract waste gas residual heat boiler electricity generation system（Water working media）, using identical thermal source and
In the case of identical output, take the system for removing Low investment to change system with high investment, actuality is lacked under national conditions.Obviously,
Because of the waste gas residual heat and the waste gas residual heat of preheater discharge that can only utilize kiln hood to extract, not using in cement production process
The device of other waste heats so that existing CO2Power generation technology is still not suitable for the cement industry of China's national situation.
So far, both at home and abroad there is not yet using 200 DEG C in the kiln hood of rotary kiln~1700 DEG C radiant heat energies directly to super
The research and practice of critical CO2 accumulation of energys, to solve the problems, such as the low-carbon emission reduction of cement production enterprise, realize the CO of cement production enterprise2Trapping and
CO2Generate electricity, in the urgent need to one kind can be using 200 DEG C~1700 DEG C hyperthermia radiation heat energy supply CO in kiln hood2The CO of generating2Accumulation of energy
Device.
The content of the invention
The technical problems to be solved by the invention be to provide it is a kind of can directly using dry-process rotory kiln production line kiln hood
