Evil element is enriched in high-temperature area, influences the stability of manufacture of cement.
(3) on hot plate furnace body, dore furnace vertebra portion, uptake flue, smoke-box slope etc. because cooperative disposal waste easily forms knot
The region of skin configures one layer of air bubble, tangential direction annular configuration of the air bubble along flow cross-sectional according to every 1~1.8m.
(4) hot plate furnace body, dore furnace vertebra portion, uptake flue, smoke-box slope castable use anti-strip high strength type
Castable.
(5) kiln tail smoke-box slope increases the configuration of castable anchoring piece according to 150~200% level of encryption, and selection is discarded
Cooler grate plate be welded on the fixed form on anchoring piece as castable construction, increase shock resistance of the slope to bulk blanking
Ability.
In addition, the environmentally friendly disposal process of the step D are as follows:
(1) device is maintained to all transloading equipments of solid waste setting negative pressure, reinforcing sealing is carried out to equipment, it is mating and perfect negative
Air draft pipe is pressed, is collected all on the spot containing peculiar smell, dusty gas, system is centrally disposed by heating and ventilating pipeline feeding.
(2) the similar gas for converging pretreatment workshop containing peculiar smell, dusty gas collected in solid waste transloading equipment leads to
It crosses after heating and ventilating pipeline completes directional collecting, cement kiln is sent into when cement producing line runs well as combustion air incineration disposal,
Matched professional deodoration system, the qualified discharge after disposing then are sent into when cement kiln is stopped transport.
(3) according to the combustion characteristics for entering hot plate furnace material, revolving speed, the ignition temperature, ventilation quantity of hot plate furnace is adjusted, is stablized
Ignition temperature is at 900~1050 DEG C, air-fuel ratio 7.5~9.5,3~20 turn/hour of revolving speed, it is ensured that enters manufacture of cement high-temperature region
The all materials in domain are thermal material, optimize burning condition, realize the abundant decomposition of organic pollutant.
(4) enter the SO of the hot raw material of kiln according to C53、Cl、M2O content detection data, switch bypass leak informaton system.Bypass
The kiln ash of system carries out heavy metal, the analysis test of harmful element access, is dissolved after closing rule as cement grinding mill mixing material.Bypass
The discharge of kiln tail smokestack is imported after the tails dedusting that leaks informaton purification.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
