Description
Technical field
The present invention relates to cement production process field, particularly relate to a kind of natural gas and dry kiln systemSystem.
Background technology
In present cement production process, most NSP rotary kilns heat up and adopt diesel oilAs fuel, and operating process mostly is Artificial Control, cannot realize automation. Diesel oil dries kilnConcrete operations flow process is:
When kiln furnitures are during for ignition condition, patrol and examine work by scene and light a torch, stretched into burnerHead. Open diesel pump, while forming flame before kiln, manual adjustments oil return valve, controls before kilnFlame intensity of fire. In the time of fray-out of flame, again carry out same program. Whole temperature-rise period is wantedAsk scene to patrol and examine and carve flame in observation kiln man-hour, with the intensification interruption that prevents that fray-out of flame from causing.
There is following shortcoming in aforesaid operations:
1, intensification overall process require to have patrol officer's moment pays close attention in kiln flame situation also andTime regulate diesel oil quantity delivered, operate comparatively loaded down with trivial details. And owing to there being malleation in kiln, easily makeBecome to see that fiery personnel are scalded by high-temperature material, exist potential safety hazard.
2, diesel oil consumption too much can cause unnecessary diesel oil to splash to refractory brick surface, causes fire-resistantBrick corrodes, and has shortened the service life of refractory brick. Therefore in temperature-rise period, see that firer will be withTime regulate diesel oil quantity delivered according to flame combustion situation.
3, diesel oil is oils, after burning, can produce nitrogen oxide, carbon monoxide,Carbon dioxide, aldehydes, can produce a large amount of black smokes when imperfect combustion, in black smoke, has without combustionBurn mist of oil, carbon granules, some high boiling heterocycle and aromatic hydrocarbon substance, and have carcinogenic substance produce as:3,4-BaP. This can cause great pollution to environment, and owing to producing carcinogen pairHuman body causes certain infringement.
The invention provides a kind of natural gas rotary kiln being heated taking natural gas as fuelDry kiln system, because natural gas belongs to clean energy resource, in combustion process, only produce water, titanium dioxideCarbon, can not pollute environment, and has realized flame detection, igniting, flame-out safety guarantorProtect and the automatic control of the technology such as safety fuel fast shut-off, really realize the nothing of kiln temperature rise periodPeople's operation. And owing to not needing personnel to see the operation such as fire and adjusting in temperature-rise period, noBut alleviate personnel's labour intensity, also avoided the scald danger causing near kilneye because of personnelDanger.
Summary of the invention
